inflation pressures needed to obtain the gross weight capacity of the vehicle. This is called Gross Vehicle Weight Rating (GVWR). The GVWR includes the weight of the vehicle, all occupants, fuel, and cargo. The Certification/Tire label also tells you the maximum weights for the front and rear axles, called Gross Axle Weight Rating (GAWR). To find out the actual loads on the front and rear axles, you need to go to a weigh station and weigh the vehicle.

Your dealer can help you with this. Be sure to spread out the load equally on both sides of the center line. Never exceed the GVWR for the vehicle, or the GAWR for either the front or rear axle. If the vehicle is carrying a heavy load, it should be spread out. See “Steps for Determining Correct Load Limit” earlier in this section.

{ WARNING

Do not load the vehicle any heavier than the Gross Vehicle Weight Rating (GVWR), or either the maximum front or rear Gross Axle Weight Rating (GAWR). If you do, parts on the vehicle can break, and it can change the way the vehicle handles. These could cause you to lose control and crash. Also, overloading can shorten the life of the vehicle.

Your warranty does not cover parts or components that fail because of overloading.

Driving and Operating

The label will help you decide how much cargo and installed equipment your truck can carry. Using heavier suspension components to get added durability might not change your weight ratings. Ask your dealer to help you load your vehicle the right way. If you put things inside your vehicle – like suitcases, tools, packages, or anything else – they will go as fast as the vehicle goes. If you have to stop or turn quickly, or if there is a crash, they will keep going.

{ WARNING

Things you put inside the vehicle can strike and injure people in a sudden stop or turn, or in a crash.

. Put things in the cargo

area of the vehicle. In the cargo area, put them as far forward as you can. Try to spread the weight evenly.

. Never stack heavier

things, like suitcases, inside the vehicle so that some of them are above the tops of the seats.

(Continued)

WARNING (Continued)

. Do not leave an

unsecured child restraint in the vehicle.

. When you carry something

inside the vehicle, secure it whenever you can.

. Do not leave a seat folded down unless you need to.

Starting and Operating

New Vehicle Break-In Notice: The vehicle does not need an elaborate break-in. But it will perform better in the long run if you follow these guidelines:

. Do not drive at any one

constant speed, fast or slow, for the first 805 km (500 miles). Do not make full-throttle starts. Avoid downshifting to brake or slow the vehicle.

. During the first 1 000 km

(600 miles), avoid using more than moderate acceleration in lower gears and avoid vehicle speeds above 110 km/h (68 mph).

. Between the first 1 000 km

(600 miles) and 5 000 km (3,000 miles), heavy acceleration in lower gears can be used. Vehicle speeds above 110 km/h (68 mph) should be limited to five minutes per use.

Driving and Operating

8-17

. Avoid making hard stops for the first 322 km (200 miles) or so. During this time the new brake linings are not yet broken in. Hard stops with new linings can mean premature wear and earlier replacement. Follow this breaking-in guideline every time you get new brake linings.

. Do not tow a trailer during

break-in. See Driving Characteristics and Towing Tips on page 8‑52 for the trailer towing capabilities of your vehicle and more information.

Following break‐in, engine speed and load can be gradually increased.

Adjustable Throttle and Brake Pedal If the vehicle has this feature, the position of the throttle and brake pedals can be adjusted.

Adjust the throttle and brake pedals while the vehicle is in P (Park) without pressing on the pedals. The pedals cannot be adjusted while the vehicle is in R (Reverse) or when cruise control is engaged. The throttle and brake pedals can also be adjusted while driving.

Ignition Positions

The switch used to adjust the pedals is located on the right side of the steering column, below the wiper stalk. Pull the switch toward you to move the pedals further from the floor, or push the switch away from you to move the pedals closer to the floor.

The vehicle has an electronic keyless ignition with push‐button start.

Pressing the button cycles it through three modes, ACC/ACCESSORY, ON/RUN/START and STOPPING THE ENGINE/OFF. If the push-button start is not working, the vehicle may be near a strong radio antenna signal causing interference to the keyless entry system. See Driver Information Center (DIC) on page 4‑29 for more information. To shift out of P (Park), the vehicle must be in ACC/ACCESSORY or ON/RUN mode and the brake pedal must be applied. STOPPING THE ENGINE/OFF (No LED Lights): When the vehicle is stopped, press the engine START/STOP button once to turn the engine off. If the vehicle is in P (Park), the ignition will turn OFF, and Retained Accessory Power (RAP) will remain active. See Retained Accessory Power (RAP) on page 8‑20 for more information.

Cadillac SRX Owner Manual - 2010

8-19

The ignition will switch from ACC/ACCESSORY to OFF after five minutes to prevent battery run down. ON/RUN/START (Green LED Light): This mode is for driving and starting. With the ignition off, and the brake pedal applied, pressing the button once will place the ignition system in ON/RUN/START. Once engine cranking begins, release the button. Engine cranking will continue until the engine starts. See Starting the Gasoline Engine on page 8‑20 for more information. The ignition will then remain in ON/RUN.

If the vehicle is not in P (Park), the ignition will return to ACC/ ACCESSORY and display the message SHIFT TO PARK in the Driver Information Center (DIC). See Driver Information Center (DIC) on page 4‑29 for more information. When the vehicle is shifted into P (Park), the ignition system will switch to OFF. Do not turn the engine off when the vehicle is moving. This will cause a loss of power assist in the brake and steering systems and disable the airbags. In an emergency: 1. Brake using a firm and steady

pressure. Do not pump the brakes repeatedly. This may deplete power assist, requiring increased brake pedal force.

2. Shift the vehicle to N (Neutral).

This can be done while the vehicle is moving. After shifting to N (Neutral), firmly apply the brakes and steer the vehicle to a safe location.

3. Come to a complete stop, shift to P (Park), and turn the ignition to LOCK/OFF. On vehicles with an automatic transmission, the shift lever must be in P (Park) to turn the ignition switch to the LOCK/OFF position.

4. Set the parking brake. See

Parking Brake on page 8‑31

ACC/ACCESSORY (Amber LED Light): This mode allows you to use some electrical accessories when the engine is off. With the ignition off, pressing the button one time without the brake pedal applied, will place the ignition system in ACC/ACCESSORY.

Retained Accessory Power (RAP) These vehicle accessories can be used for up to 10 minutes after the engine is turned off: . Audio System . Power Windows . Sunroof (if equipped) . Power outlets under the climate control system, inside the center floor console, and on the rear of the center floor console.

Power to the audio system will continue to operate for up to 10 minutes or until the driver door is opened. Power to the power windows, sunroof and outlets under the climate control system, inside the center floor console, and on the rear of the center floor console will continue to operate for up to 10 minutes or until any door is opened.

All these features will work when the vehicle is in ON/RUN/START.

Starting the Gasoline Engine Place the transmission in the proper gear by moving the shift lever to P (Park) or N (Neutral). To restart the engine when the vehicle is already moving, use N (Neutral). Notice: Do not try to shift to P (Park) if the vehicle is moving. If you do, you could damage the transmission. Shift to P (Park) only when the vehicle is stopped. The keyless access transmitter must be inside the vehicle for the ignition to work. Cell phone chargers can interfere with the operation of the Keyless Access System. Battery chargers should not be plugged in when starting or turning off the engine.

To start the vehicle:

Starting Procedure 1. With the brake pedal applied,

press the START button located on the instrument panel. See Ignition Positions on page 8‑18.

2. When the engine begins

cranking, let go of the button and the engine cranks automatically until it starts. If the transmitter is not in the vehicle or something is interfering with the transmitter, the Driver Information Center (DIC) will display No Remote Detected. See Driver Information Center (DIC) on page 4‑29 for more information. If the battery in the keyless access transmitter needs replacing, the DIC displays Replace Battery In Remote Key. The vehicle can still be driven. See Remote Keyless Entry (RKE) System Operation on page 1‑3 for more information.

immediately after starting it. Operate the engine and transmission gently until the oil warms up and lubricates all moving parts. If the engine does not start and no DIC message is displayed, wait 15 seconds before trying again to let the cranking motor cool down. If the engine does not start after 5-10 seconds, especially in very cold weather (below −18°C or 0°F), it could be flooded with too much gasoline. Try pushing the accelerator pedal all the way to the floor while cranking for up to 15 seconds.

Notice: Cranking the engine for long periods of time, by pressing the START button immediately after cranking has ended, can overheat and damage the cranking motor, and drain the battery. Wait at least 15 seconds between each try, to allow the cranking motor to cool down. When the engine starts, let go of the accelerator. If the vehicle starts briefly but then stops again, do the same thing. This clears the extra gasoline from the engine. The vehicle has a Computer-Controlled Cranking System. This feature assists in starting the engine and protects components. Once cranking has been initiated, the engine continues

cranking for a few seconds or until the vehicle starts. If the engine does not start, cranking automatically stops after 15 seconds to prevent cranking motor damage. To prevent gear damage, this system also prevents cranking if the engine is already running. Notice: The engine is designed to work with the electronics in the vehicle. If you add electrical parts or accessories, you could change the way the engine operates. Before adding electrical equipment, check with your dealer. If you do not, the engine might not perform properly. Any resulting damage would not be covered by the vehicle warranty.

Engine Heater The engine coolant heater, if available, can help in cold weather conditions at or below −18°C (0°F) for easier starting and better fuel economy during engine warm-up. Plug in the coolant heater at least four hours before starting the vehicle. An internal thermostat in the plug-end of the cord will prevent engine coolant heater operation at temperatures above −18°C (0°F). To Use The Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the

electrical cord. The cord is located near the air cleaner.

3. Plug it into a normal, grounded

110-volt AC outlet.

{ WARNING Plugging the cord into an ungrounded outlet could cause an electrical shock. Also, the wrong kind of extension cord could overheat and cause a fire. You could be seriously injured. Plug the cord into a properly grounded three-prong 110-volt AC outlet. If the cord will not reach, use a heavy-duty three-prong extension cord rated for at least 15 amps.

4. Before starting the engine, be

sure to unplug and store the cord as it was before to keep it away from moving engine parts. If you do not it could be damaged.

The length of time the heater should remain plugged in depends on several factors. Ask a dealer in the area where you will be parking the vehicle for the best advice on this.

Shifting Into Park { WARNING

It can be dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, use the steps that follow.

1. Hold the brake pedal down and

set the parking brake. See Parking Brake on page 8‑31 for more information. 2. Move the shift lever into P (Park) by pushing the lever all the way toward the front of the vehicle.

Leaving the Vehicle With the Engine Running

{ WARNING

It can be dangerous to leave the vehicle with the engine running. The vehicle could move suddenly if the shift lever is not fully in P (Park) with the parking brake firmly set. And, if you leave the vehicle with the engine running, it could overheat and even catch fire. You or others could be injured. Do not leave the vehicle with the engine running.

If you have to leave the vehicle with the engine running, be sure the vehicle is in P (Park) and the parking brake is firmly set before you leave it. After you have moved the shift lever into P (Park), hold down the regular brake pedal.

See if you can move the shift lever away from P (Park) without first pulling it toward you. If you can, it means that the shift lever was not fully locked into P (Park). Torque Lock Torque lock is when the weight of the vehicle puts too much force on the parking pawl in the transmission. This happens when parking on a hill and shifting the transmission into P (Park) is not done properly and then it is difficult to shift out of P (Park). To prevent torque lock, set the parking brake and then shift into P (Park). To find out how, see "Shifting Into P (Park)" listed previously. If torque lock does occur, your vehicle may need to be pushed uphill by another vehicle to relieve the parking pawl pressure, so you can shift out of P (Park).

Shifting Out of Park This vehicle is equipped with an electronic shift lock release system. The shift lock release is designed to prevent movement of the shift lever out of P (Park), unless the ignition is in ON/RUN or ACC/ACCESSORY and the brake pedal is applied. The shift lock release is always functional except in the case of an uncharged or low voltage (less than 9 volt) battery. If the vehicle has an uncharged battery or a battery with low voltage, try charging or jump starting the battery. See Jump Starting on page 9‑101. To shift out of P (Park): 1. Apply the brake pedal. 2. Press the shift lever button. 3. Move the shift lever to the

desired position.

{ WARNING

Things that can burn could touch hot exhaust parts under the vehicle and ignite. Do not park over papers, leaves, dry grass, or other things that can burn.

Engine Exhaust { WARNING

Engine exhaust contains Carbon Monoxide (CO) which cannot be seen or smelled. Exposure to CO can cause unconsciousness and even death. Exhaust may enter the vehicle if:

. The vehicle idles in areas

with poor ventilation (parking garages, tunnels, deep snow that may block underbody airflow or tail pipes).

. The exhaust smells or

sounds strange or different.

. The exhaust system leaks

due to corrosion or damage.

(Continued)

WARNING (Continued)

. The vehicle’s exhaust system has been modified, damaged or improperly repaired.

. There are holes or openings

in the vehicle body from damage or after-market modifications that are not completely sealed.

If unusual fumes are detected or if it is suspected that exhaust is coming into the vehicle:

. Drive it only with the windows

completely down.

. Have the vehicle repaired

immediately.

Never park the vehicle with the engine running in an enclosed area such as a garage or a building that has no fresh air ventilation.

Driving and Operating

Make sure the shift lever is fully in P (Park) before starting the engine. The vehicle has an automatic transmission shift lock control system. You must fully apply the regular brakes first and then press the shift lever button before you can shift from P (Park) when the ignition is in ON/RUN. If you cannot shift out of P (Park), ease pressure on the shift lever and push the shift lever all the way into P (Park) as you maintain brake application. Then press the shift lever button and move the shift lever into another gear. See Shifting Out of Park on page 8‑23 .

Notice: Shifting to R (Reverse) while the vehicle is moving forward could damage the transmission. The repairs would not be covered by the vehicle warranty. Shift to R (Reverse) only after the vehicle is stopped. R (Reverse): Use this gear to back up. At low vehicle speeds, R (Reverse) can be used to rock the vehicle back and forth to get out of snow, ice, or sand without damaging your transmission. See If the Vehicle is Stuck on page 8‑11 for additional information.

P (Park): This position locks the front wheels. It is the best position to use when you start the engine because the vehicle cannot move easily.

{ WARNING

It is dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll. Do not leave the vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to P (Park). See Shifting Into Park on page 8‑22 .

Downshifting the transmission in slippery road conditions could result in skidding, see Skidding under Loss of Control on page 8‑6. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place.

N (Neutral): In this position, the engine does not connect with the wheels. To restart when the vehicle is already moving, use N (Neutral) only. You can also use N (Neutral) when the vehicle is being towed.

{ WARNING

Shifting into a drive gear while the engine is running at high speed is dangerous. Unless your foot is firmly on the brake pedal, the vehicle could move very rapidly. You could lose control and hit people or objects. Do not shift into a drive gear while the engine is running at high speed.

Notice: Shifting out of P (Park) or N (Neutral) with the engine running at high speed may damage the transmission. The repairs would not be covered by the vehicle warranty. Be sure the engine is not running at high speed when shifting the vehicle. D (Drive): This position is for normal driving. It provides the best fuel economy. If you need more power for passing, and you are: . Going less than 35 mph

(55 km/h), push the accelerator pedal about halfway down.

. Going about 35 mph (55 km/h)

or more, push the accelerator all the way down. The transmission will shift down to a lower gear and have more power.

Driving and Operating

An S will be displayed in the DIC. Within Sport Mode there is a further performance feature called Performance Mode Lift Foot (PMLF) Mode. The feature is activated automatically when sports oriented driving is detected, based on cornering and on/off throttle application. PMLF allows the transmission to hold the current gear instead of upshifting when the throttle is lifted.

2. To enter M (Manual Mode), press

the shift lever forward to upshift or rearward to downshift. An M will be displayed in the DIC.

Manual Mode

Driver Shift Control (DSC) Notice: If you drive the vehicle at high RPMs without upshifting while using Driver Shift Control (DSC), you could damage the vehicle. Always upshift when necessary while using DSC. Driver Shift Control (DSC) allows you to shift an automatic transmission similar to a manual transmission. To use the DSC feature: 1. Move the shift lever to the left

from D (Drive) to M (Manual Mode). If you do not move the shift lever forward or rearward, the vehicle will be in Sport Mode. When you are in Sport Mode the vehicle will still shift automatically. The transmission may remain in a gear longer than it would in the normal driving mode based on braking, throttle input, and vehicle lateral acceleration.

The tachometer display on the instrument panel cluster will show which gear the vehicle is in. The number indicates the requested gear range when moving the shift lever forward or rearward. See Tachometer on page 4‑15 for more information. While using the DSC feature, the vehicle will have firmer, quicker shifting. You can use this for sport driving or when climbing or descending hills, to stay in gear longer, or to down shift for more power or engine braking.

Cadillac SRX Owner Manual - 2010

Black plate (29,1)

Driving and Operating

8-29

When fuel economy mode is on: The transmission will upshift sooner, and downshift later. The torque converter will lock–up sooner, and stay on longer. The gas pedal will be less sensitive. The vehicle's computers will more aggressively shut off fuel to the engine under deceleration.

The transmission will only allow you to shift into gears appropriate for the vehicle speed and engine Revolutions Per Minute (RPM). The transmission will not automatically shift to the next lower gear if the engine RPM is too high, nor to the next higher gear when the maximum engine RPM is reached. If shifting is prevented for any reason, the currently selected gear will flash multiple times, indicating that the transmission has not shifted gears. While in the DSC mode, the transmission will automatically downshift when the vehicle comes to a stop. This will allow for more power during take-off. When accelerating the vehicle from a stop in snowy and icy conditions, you may want to shift into second gear. A higher gear ratio allows you to gain more traction on slippery surfaces.

Fuel Economy Mode The vehicle may have a fuel economy mode. When engaged, fuel economy mode can improve the vehicle's fuel economy.

Pressing the eco button by the shift lever will engage fuel economy mode. When activated, the eco light in the instrument cluster will come on. See Fuel Economy Light on page 4‑27 . Pressing the button a second time will turn fuel economy mode off.

Driving and Operating

Drive Systems

Brakes

All-Wheel Drive Vehicles with this feature always send engine power to all four wheels. It is fully automatic, and adjusts itself as needed for road conditions. When using a compact spare tire on an AWD vehicle, the system automatically detects the compact spare and disables AWD. To restore AWD operation and prevent excessive wear on the system, replace the compact spare with a full-size tire as soon as possible. See Compact Spare Tire on page 9‑100 for more information.

Antilock Brake System (ABS) This vehicle has the Antilock Brake System (ABS), an advanced electronic braking system that helps prevent a braking skid. When the engine is started and the vehicle begins to drive away, ABS checks itself. A momentary motor or clicking noise might be heard while this test is going on, and it might even be noticed that the brake pedal moves a little. This is normal.

If driving safely on a wet road and it becomes necessary to slam on the brakes and continue braking to avoid a sudden obstacle, a computer senses that the wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each wheel. ABS can change the brake pressure to each wheel, as required, faster than any driver could. This can help the driver steer around the obstacle while braking hard. As the brakes are applied, the computer keeps receiving updates on wheel speed and controls braking pressure accordingly.

If there is a problem with ABS, this warning light stays on. See Antilock Brake System (ABS) Warning Light on page 4‑24 .

Cadillac SRX Owner Manual - 2010

Black plate (31,1)

Remember: ABS does not change the time needed to get a foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, there will not be enough time to apply the brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even with ABS. Using ABS Do not pump the brakes. Just hold the brake pedal down firmly and let ABS work. You might hear the ABS pump or motor operating and feel the brake pedal pulsate, but this is normal. Braking in Emergencies ABS allows the driver to steer and brake at the same time. In many emergencies, steering can help more than even the very best braking.

Parking Brake

Driving and Operating

8-31

The system has a Park Brake Status light and a Park Brake Warning light. See Brake System Warning Light on page 4‑23 . There are also three Driver Information Center (DIC) messages. See Driver Information Center (DIC) on page 4‑29 for more information. In case of insufficient electrical power, the EPB cannot be applied or released. Before leaving the vehicle, check the park brake status lamp to insure the park brake is applied.

The vehicle has an Electric Parking Brake (EPB). The switch for the EPB is in the center console. The EPB can always be activated, even if the ignition is OFF. To avoid draining the battery, do not cycle the EPB too often without the engine running. The EPB can be left applied while the vehicle is parked.

Cadillac SRX Owner Manual - 2010

Black plate (32,1)

8-32

Driving and Operating

EPB Apply The EPB can be applied any time the vehicle is stopped. The EPB is applied by momentarily lifting up on the EPB switch. Once fully applied, the park brake status light will be on. While the brake is being applied, the status lamp will flash until full apply is reached. If the light does not come on, or remains flashing, you need to have the vehicle serviced. Do not drive the vehicle if the park brake status light is flashing. See your dealer. See Brake System Warning Light on page 4‑23 for more information. If the EPB is applied while the vehicle is in motion, a chime will sound, and the DIC message “Release Park Brake” will be displayed. The vehicle will decelerate as long as the switch is held in the up position. Releasing the EPB switch during the deceleration will release the parking brake. If the switch is held in the up position until the vehicle comes to a stop, the EPB will remain applied.

If the park brake status light flashes continuously, the EPB is only partially applied or released, or there is a problem with the EPB. The DIC message “Service Parking Brake” will be displayed. If this light flashes continuously, release the EPB, and attempt to apply it again. If this light continues to flash, do not drive the vehicle. See your dealer. If the park brake warning light is on, the EPB has detected an error in another system and is operating with reduced functionality. To apply the EPB when this light is on, lift up on the EPB switch and hold it in the up position. Full application of the parking brake by the EPB system may take a longer period of time than normal when this light is on. Continue to hold the switch until the park brake status light remains on. If the park brake warning light is on, see your dealer. If the EPB fails to apply, the rear wheels should be blocked to prevent vehicle movement.

EPB Release To release the EPB, place the ignition in the ON/RUN position, apply and hold the brake pedal, and push down momentarily on the EPB switch. If you attempt to release the EPB without the brake pedal applied, a chime will sound, and the DIC message “Step On Brake to Release Park Brake” will be displayed. The EPB is released when the park brake status light is off. If the park brake warning light is on, the EPB has detected an error in another system and is operating with reduced functionality. To release the EPB when this light is on, push down on the EPB switch and hold it in the down position.

Cadillac SRX Owner Manual - 2010

Black plate (33,1)

EPB release may take a longer period of time than normal when this light is on. Continue to hold the switch until the park brake status light is off. If the light is on, see your dealer. Notice: Driving with the parking brake on can overheat the brake system and cause premature wear or damage to brake system parts. Make sure that the parking brake is fully released and the brake warning light is off before driving. Automatic EPB Release The EPB will automatically release if the vehicle is running, placed into gear and an attempt is made to drive away. Avoid rapid acceleration when the EPB is applied, to preserve park brake lining life. If you are towing a trailer and parking on a hill, see Driving Characteristics and Towing Tips on page 8‑52 for more information.

Brake Assist This vehicle has a brake assist feature designed to assist the driver in stopping or decreasing vehicle speed in emergency driving conditions. This feature uses the stability system hydraulic brake control module to supplement the power brake system under conditions where the driver has quickly and forcefully applied the brake pedal in an attempt to quickly stop or slow down the vehicle. The stability system hydraulic brake control module increases brake pressure at each corner of the vehicle until the ABS activates. Minor brake pedal pulsation or pedal movement during this time is normal and the driver should continue to apply the brake pedal as the driving situation dictates. The brake assist feature will automatically disengage when the brake pedal is released or brake pedal pressure is quickly decreased.

Driving and Operating

8-33

Hill Start Assist (HSA) This vehicle has a Hill Start Assist (HSA) feature, which may be useful when the vehicle is stopped on a grade. This feature is designed to prevent the vehicle from rolling, either forward or rearward, during vehicle drive off. After driver completely stops and holds the vehicle in a complete standstill on a grade, HSA will be automatically activated. During the transition period between when the driver releases the brake pedal and starts to accelerate to drive off on a grade, HSA holds the braking pressure to ensure that there is no rolling back. The brakes will automatically release when the accelerator pedal is applied within the two second window. It will not activate if the vehicle is in a drive gear and facing downhill or if the vehicle is facing uphill and in R (Reverse).

Traction Control System (TCS) The vehicle may have a Traction Control System (TCS) that limits wheel spin. On a front-wheel-drive vehicle, the system operates if it senses that one or both of the front wheels are spinning or beginning to lose traction. On an All-Wheel-Drive (AWD) vehicle, the system will operate if it senses that any of the wheels are spinning or beginning to lose traction. When this happens, the system brakes the spinning wheel(s) and/or reduces engine power to limit wheel spin. The system may be heard or felt while it is working, but this is normal.

TCS automatically comes on whenever the vehicle is started. To limit wheel spin, especially in slippery road conditions, the system should always be left on. But, TCS can be turned off if needed.

TCS/StabiliTrak Light d flashes to indicate that the traction control system is active. If there is a problem detected with TCS, “Service Traction Control” is displayed on the Driver Information Center (DIC). See Ride Control System Messages on page 4‑38 .

When this message is displayed and d comes on and stays on, the vehicle is safe to drive but the system is not operational. Driving should be adjusted accordingly. If d comes on and stays on, reset the system by: 1. Stopping the vehicle. 2. Turning the engine off and

waiting 15 seconds. 3. Starting the engine. If d still comes on and stays on, the vehicle needs service.

Driving should be adjusted accordingly. Press and release d again to turn the system back on. When TCS is turned off on AWD vehicles, the system may still make noise. This is normal and necessary with AWD hardware. It may be necessary to turn the system off if the vehicle gets stuck in sand, mud or snow and rocking the vehicle is required. See If the Vehicle is Stuck on page 8‑11 for more information. See also Winter Driving on page 8‑9 for information on using TCS when driving in snowy or icy conditions. Adding non‐GM accessories can affect the vehicle's performance. See Accessories and Modifications on page 9‑3 for more information.

StabiliTrak® System The vehicle may have a vehicle stability enhancement system called StabiliTrak. It is an advanced computer controlled system that assists with directional control of the vehicle in difficult driving conditions. StabiliTrak activates when the computer senses a difference between the intended path and the direction the vehicle is actually traveling. StabiliTrak selectively applies braking pressure at any one of the vehicle's brakes to help steer the vehicle in the intended direction. StabiliTrak comes on automatically whenever the vehicle is started. To assist with directional control of the vehicle, the system should always be left on.

Notice: Do not repeatedly brake or accelerate heavily when TCS is off. The vehicle's driveline could be damaged.

Limited-Slip Rear Axle Vehicles with a limited-slip rear axle can give more traction on snow, mud, ice, sand, or gravel. When traction is low, this feature allows the drive wheel with the most traction to move the vehicle. The limited-slip rear axle also gives the driver enhanced control when cornering hard or completing a maneuver, such as a lane change.

Selective Ride Control The vehicle may have a ride control system called Selective Ride Control. The setting can be changed at any time. Based on road conditions, steering wheel angle and the vehicle speed, the system automatically adjusts to provide the best handling while providing a smooth ride. The Tour and Sport modes will feel similar on a smooth road.

To switch from TOUR to SPORT mode, move the shift lever to the left while the transmission is in D (Drive) TOUR: Use for normal city and highway driving. This setting provides a smooth, soft ride. SPORT: Use where road conditions or personal preference demand more control. This setting provides more “feel”, or response to road conditions through increased steering effort and suspension control. Transmission shift points and shift firmness are also enhanced. See Manual Mode on page 8‑28 in Automatic Transmission. If there is a problem detected with Selective Ride Control, “Service Suspension System” displays on the Driver Information Center (DIC). See Ride Control System Messages on page 4‑38 . Driving should be adjusted accordingly.

Cruise Control

{ WARNING

Cruise control can be dangerous where you cannot drive safely at a steady speed. So, do not use the cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads.

With cruise control, a speed of about 40 km/h (25 mph) or more can be maintained without keeping your foot on the accelerator. Cruise control does not work at speeds below about 40 km/h (25 mph). If the brakes are applied, the cruise control shuts off.

If the vehicle has the StabiliTrak® system and begins to limit wheel spin while using cruise control, the cruise control automatically disengages. See StabiliTrak® System on page 8‑35 or Traction Control System (TCS) on page 8‑34 . When road conditions allow the cruise control to be safely used, you can apply the cruise control again.

Cruise Control

The cruise control buttons are located on the left side of the steering wheel.

T (On/Off): Press to turn the system on and off. + RES (Resume/Accelerate): Press briefly to make the vehicle resume to a previously set speed or press and hold to accelerate. −SET (Set/Coast): Press to set the speed and activate cruise control or make the vehicle decelerate. [ (Cancel): Press to disengage cruise control without erasing the set speed from memory.

Setting Cruise Control If the cruise button is on when not in use, it could get bumped and go into cruise when not desired. Keep the cruise control switch off when cruise is not being used.

The cruise control light on the instrument panel cluster comes on after the cruise control has been set to the desired speed. 1. Press T. 2. Get up to the desired speed. 3. Press and release the −SET

button located on the steering wheel.

4. Take your foot off the

accelerator.

Resuming a Set Speed If the cruise control is set at a desired speed and then the brakes are applied, the cruise control is disengaged without erasing the set speed from memory. Once the vehicle speed reaches about 40 km/h (25 mph) or more, press the +RES button on the steering wheel. The vehicle returns to the previous set speed and stays there.

Object Detection Systems

Ultrasonic Parking Assist For vehicles with the Ultrasonic Front and Rear Parking Assist (UFRPA) system, it assists the driver with parking and avoiding objects. UFRPA operates at speeds less than 8 km/h (5 mph), and the sensors on the front and rear bumper detect objects up to 1.2 m (4 ft) in front of the vehicle and 2.5 m (8 ft) behind the vehicle, and at least 25.4 cm (10 in) off the ground.

{ WARNING

The Ultrasonic Front and Rear Park Assist (UFRPA) system does not replace driver vision. It cannot detect:

. objects that are below the

bumper, underneath the vehicle, or if they are too close or far from the vehicle

. children, pedestrians,

bicyclists, or pets.

If you do not use proper care before moving forward and while backing; vehicle damage, injury, or death could occur. Even with UFRPA, always check in front of the vehicle before moving forward and behind the vehicle before backing up. While moving forward and backing, be sure to look for objects and check the vehicle's mirrors.

How the System Works When the vehicle is shifted into R (Reverse) the front and rear sensors are automatically turned on, after the vehicle is shifted out of R (Reverse), the rear sensors are turned off and the front sensors stay on until the vehicle is above a certain speed. The front sensors may also be turned on by pressing the park assist button located next to the shift lever without shifting into R (Reverse) while the vehicle is traveling at a low speed. See “Turning the System On and Off” later in this section. When the vehicle is in N (Neutral), the system may be active. If the vehicle is in a car wash, the sensors may detect objects in the car wash. See “Turning the System On and Off” later in this section to turn the system off.

Cadillac SRX Owner Manual - 2010

High-toned beeps heard from the front speakers are for objects detected near the front bumper. Low-toned beeps heard from the rear speakers are for objects detected near the rear bumper. When an object is detected, high or low‐tone beeps are heard. As the vehicle gets closer to an object, the time between the beeps becomes shorter. When the distance is less than 30 cm (11.8 in), beeping is continuous. The distance may be less during warmer or humid weather. PARK ASSIST OFF displays on the Driver Information Center (DIC) to indicate that UFRPA is off. The message disappears after a short period of time.

When the System Does Not Seem to Work Properly If UFRPA does not turn on due to a temporary condition, the message PARK ASSIST OFF displays on the DIC, and the light on the park assist button turns off. This can occur under the following conditions:

The ultrasonic sensors are not clean. Keep the vehicle's bumpers free of mud, dirt, snow, ice and slush. For cleaning instructions, see Exterior Care on page 9‑109.

. A trailer was attached to the

vehicle, or an object was hanging out of the liftgate during the last drive cycle. Once the attached object is removed, UFRPA will return to normal operation.

If an object is attached to the front of the vehicle.

. A tow bar is attached to the

vehicle. The vehicle's bumper is damaged. Take the vehicle to your dealer to repair the system.

. Other conditions may affect

system performance, such as vibrations from a jackhammer or the compression of air brakes on a very large truck.

Fuel Use of the recommended fuel is an important part of the proper maintenance of this vehicle. To help keep the engine clean and maintain optimum vehicle performance, we recommend the use of gasoline advertised as TOP TIER Detergent Gasoline. Look for the TOP TIER label on the fuel pump to ensure gasoline meets enhanced detergency standards developed by auto companies. A list of marketers providing TOP TIER Detergent Gasoline can be found at www.toptiergas.com.

When the System Does Not Seem To Work Properly The rear vision camera system may not work properly or display a clear image if:

The RVC is turned off. See “Turning the Rear Camera System On or Off” earlier in this section. It is dark. The sun or the beam of headlights is shining directly into the camera lens. Ice, snow, mud, or anything else builds up on the camera lens. Clean the lens, rinse it with water, and wipe it with a soft cloth. The back of the vehicle is in an accident, the position and mounting angle of the camera can change or the camera can be affected. Be sure to have the camera and its position and mounting angle checked at your dealer.

The 8th digit of the Vehicle Identification Number (VIN) shows the code letter or number that identifies the vehicle's engine.

The VIN is at the top left of the instrument panel. See Vehicle Identification Number (VIN) on page 11‑1 .

Recommended Fuel If the vehicle has the 3.0L V6 engine (VIN Code Y), use regular unleaded gasoline with a posted octane rating of 87 or higher. If the octane rating is less than 87, an audible knocking noise, commonly referred to as spark knock, might be heard when driving. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. If heavy knocking is heard when using gasoline rated at 87 octane or higher, the engine needs service.

If the vehicle has the 2.8L V6 engine (VIN Code 4), use premium unleaded gasoline with a posted octane rating of 91 or higher. For best performance, use premium unleaded gasoline with a posted octane rating of 93. In an emergency, you can use regular unleaded gasoline with an octane rating of 87 or higher. If 87 octane fuel is used, do not perform any aggressive driving maneuvers such as wide open throttle applications. You might also hear audible spark knock during acceleration. Refill the tank with premium fuel as soon as possible to avoid damaging the engine. If heavy knocking is heard when using gasoline rated at 91octane or higher, the engine needs service.

Gasoline Specifications At a minimum, gasoline should meet ASTM specification D 4814
in the United States or CAN/ CGSB‐3.5 or 3.511 in Canada. Some gasolines contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). We recommend against the use of gasolines containing MMT. See Fuel Additives on page 8‑48 for additional information.

Fuels in Foreign Countries If you plan on driving in another country outside the United States or Canada, the proper fuel might be hard to find. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel would not be covered by the vehicle warranty. To check the fuel availability, ask an auto club, or contact a major oil company that does business in the country where you will be driving.

California Fuel Requirements If the vehicle is certified to meet California Emissions Standards, it is designed to operate on fuels that meet California specifications. See the underhood emission control label. If this fuel is not available in states adopting California emissions standards, the vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance might be affected. The malfunction indicator lamp could turn on and the vehicle might fail a smog‐check test. See Malfunction Indicator Lamp on page 4‑20 . If this occurs, return to your authorized dealer for diagnosis. If it is determined that the condition is caused by the type of fuel used, repairs might not be covered by the vehicle warranty.

Fuel Additives To provide cleaner air, all gasolines in the United States are now required to contain additives that help prevent engine and fuel system deposits from forming, allowing the emission control system to work properly. In most cases, nothing should have to be added to the fuel. However, some gasolines contain only the minimum amount of additive required to meet U.S. Environmental Protection Agency regulations. To help keep fuel injectors and intake valves clean, or if the vehicle experiences problems due to dirty injectors or valves, look for gasoline that is advertised as TOP TIER Detergent Gasoline. Look for the TOP TIER label on the fuel pump to ensure gasoline meets enhanced detergency standards developed by the auto companies. A list of marketers providing TOP TIER Detergent Gasoline can be found at www.toptiergas.com.

However, E85 (85% ethanol) and other fuels containing more than 10% ethanol must not be used in vehicles that were not designed for those fuels. Notice: This vehicle was not designed for fuel that contains methanol. Do not use fuel containing methanol. It can corrode metal parts in the fuel system and also damage plastic and rubber parts. That damage would not be covered under the vehicle warranty.

Some gasolines that are not reformulated for low emissions can contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. We recommend against the use of such gasolines. Fuels containing MMT can reduce the life of spark plugs and the performance of the emission control system could be affected. The malfunction indicator lamp might turn on. If this occurs, return to your dealer for service.

For customers who do not use TOP TIER Detergent Gasoline regularly, one bottle of GM Fuel System Treatment PLUS, added to the fuel tank at every engine oil change, can help clean deposits from fuel injectors and intake valves. GM Fuel System Treatment PLUS is the only gasoline additive recommended by General Motors. It is available at your dealer. Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines might be available in your area. We recommend that you use these gasolines, if they comply with the specifications described earlier.
