wheel drive with vehicle stability assist (VSA), but does not have the advantages of SH-AWD. Have your vehicle checked by a dealer as soon as possible.

If the SH-AWD indicator on the instrument panel stays on, and the ‘‘CHECK SH-AWD SYSTEM’’ message also appears on the multi- information display, there is problem with the SH-AWD system.

If the SH-AWD indicator blinks while driving, it indicates the differential temperature is too high. You will also see an ‘‘SH-AWD DIFF TEMP. HIGH’’ message on the multi- information display. If this happens, pull to the side of the road when it is safe, shift to Park, and let the engine idle until the indicator goes out. If the indicator does not go out, take your vehicle to a dealer to have it checked.

Parking

Always use the parking brake when you park your vehicle. Make sure the parking brake is set firmly, or your vehicle may roll if it is parked on an incline. Set the parking brake before you put the transmission in Park. This keeps the vehicle from moving and putting pressure on the parking mechanism in the transmission.

Parking Tips ● Make sure the moonroof and the

windows are closed.

● Turn off the lights. ● Place any packages, valuables, etc. in the cargo area or take them with you.

● Lock the doors and the tailgate.

● Never park over dry leaves, tall

grass, or other flammable materials. The hot three way catalytic converter could cause these materials to catch on fire.

● If the vehicle is facing uphill, turn

the front wheels away from the curb.

● If the vehicle is facing downhill, turn the front wheels toward the curb.

● Check the indicator on the

instrument panel to verify that the security system is set.

● Make sure the parking brake is

fully released before driving away. Driving with the parking brake partially set can overheat or damage the rear brakes.

Your vehicle is equipped with a tire pressure monitoring system (TPMS) that turns on every time you start the engine and monitors the pressure in your tires while driving. Each tire has its own pressure sensor. If the air pressure of a tire becomes significantly low, the sensor in that tire immediately sends a signal that causes the low tire pressure/TPMS indicator in the instrument panel to come on. If this happens, you will see which tire is losing pressure on the multi- information display along with a ‘‘CHECK TIRE PRESSURE’’ message.

Tire Pressure Monitoring System (TPMS)

Low Tire Pressure/ TPMS Indicator

When the low tire pressure/TPMS indicator is on, one or more of your tires is significantly underinflated. You should stop and check your tires as soon as possible, and inflate them to the proper pressure as indicated on the vehicle's tire information placard. It is possible that the pressures shown on the multi-information display and the pressures you manually measure are slightly different. If the difference is significant or you cannot make the low tire pressure/ TPMS indicator and message on the multi-information display go out after inflating the tires to the specified values, have your dealer check the system as soon as possible.

If you think you can safely drive a short distance to a service station, proceed slowly to the station, then inflate the tire to the recommended pressure. If the tire is flat, or if the tire pressure is too low to continue driving, replace the tire with the compact spare tire (see page 547). Driving on a significantly under- inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Because tire pressure varies by temperature and other conditions, the low tire pressure/TPMS indicator may come on unexpectedly.

CONTINUED 451

Tire Pressure Monitoring System (TPMS)

Tire Pressure Monitor

Although your tire pressure is monitored, you must manually check the tire pressures monthly. Each tire, including the spare, should be checked monthly when the vehicle is cold, and set to the recommended inflation pressure as specified on the vehicle placard and in the owner's manual (see page 537).

To select the tire pressure monitor, press the INFO button several times with the ignition switch in the ON (II) position. You will see the above display on the multi-information display when all tire pressures are normal.

For example, if you check and fill your tires in a warm area, then drive in extremely cold weather, the tire pressure will be lower than measured and could be underinflated and cause the low tire pressure/ TPMS indicator to come on. Or, if you check and adjust your tire pressure in cooler conditions, and drive into extremely hot conditions, the tire may become overinflated. However, the low tire pressure/ TPMS indicator will not come on if the tires are overinflated. Refer to page 536 for tire inflation guidelines. If there is a problem with the TPMS, this indicator begins to flash. It stops flashing after approximately 1
minute, then stays on. You will also see a ‘‘CHECK TPMS SYSTEM’’ message on the multi-information display (see page 87).

To see the inflation pressures of all four tires, press the SEL/RESET button. The display changes as shown above.

Each tire pressure is shown in PSI (U.S. models) or in kPa (Canadian models).

This shows that front left tire is losing pressure.

Each tire has its own pressure sensor. If the air pressure of a tire becomes significantly low, the sensor in that tire immediately sends a signal that causes the low tire pressure/TPMS indicator in the instrument panel to come on. If this happens, you will see which tire is losing pressure on the multi- information display along with a ‘‘CHECK TIRE PRESSURE’’ message.

CONTINUED 453

Tire Pressure Monitoring System (TPMS)

TPMS System Failure

If any of the tires has low pressure, the tire pressure monitor also shows the above message to warn you about the low tire pressure when you select the display by pressing the INFO button several times. Following this display, press the SEL/RESET button to see each tire pressure. When you continue driving after installing the spare tire, you will also see this message on the multi- information display.

If there is a problem with the TPMS, the tire pressure monitor shows a ‘‘SYSTEM FUNCTION ERROR’’ message and the tire pressure readings are not displayed. If this happens, you will first see a system warning message ‘‘CHECK TPMS SYSTEM’’ on the multi-information display.

If there is a problem with the TPMS, you will see the above message on the multi-information display. If you see this message, the system is off and is not monitoring the tire pressures. Have the system checked by your dealer as soon as possible. Also, the low tire pressure/TPMS indicator begins to flash, then stays on (see page 451).

454

Tire Pressure Monitoring System (TPMS)

After the flat tire is replaced with the spare tire, the low tire pressure/ TPMS indicator stays on while driving. After several miles (kilometers) driving, this indicator begins to flash, then stays on again. You will also see a ‘‘CHECK TPMS SYSTEM’’ message on the multi- information display. This is normal; the system cannot monitor the spare tire pressure. Manually check the spare tire pressure to be sure it is correct.

This indicator and the warning message on the multi-information display will go off, after several miles (kilometers) driving, when the spare tire is replaced with the specified regular tire equipped with the tire pressure monitor sensor. Each wheel is equipped with a tire pressure sensor mounted inside the tire behind the valve stem. You must use TPMS specific wheels. It is recommended that you always have your tires serviced by your dealer or a qualified technician. Never use a puncture-repairing agent in a flat tire. If used, you will have to replace the tire pressure sensor. Have the flat tire repaired by your dealer as soon as possible.

If the low tire pressure/TPMS indicator comes on, or the multi- information display shows a ‘‘CHECK TPMS SYSTEM’’ message, the VSA system automatically turns on even when the VSA system is turned off by pressing the VSA OFF switch (see page 470). If this happens, you cannot turn the VSA system off by pressing the VSA OFF switch again. When you restart the vehicle with the compact spare tire, the TPMS system message will also be displayed on the multi-information display after several miles (kilometers) driving. Changing a Tire with TPMS If you have a flat tire, the low tire pressure/TPMS and tire monitor indicators will come on. Replace the indicated flat tire with the compact spare tire (see page 547).

Braking System Your vehicle is equipped with disc brakes at all four wheels. A power assist helps reduce the effort needed on the brake pedal. The emergency brake assist system increases the stopping force when you depress the brake pedal hard in an emergency situation. The anti-lock brake system (ABS) helps you retain steering control when braking very hard. Resting your foot on the pedal keeps the brakes applied lightly, builds up heat, and reduces their effectiveness and reduces brake pad life. In addition, fuel economy can be reduced. It also keeps your brake lights on all the time, confusing drivers behind you.

Constant application of the brakes when going down a long hill builds up heat and reduces their effectiveness. Use the engine to assist the brakes by taking your foot off the accelerator and downshifting to a lower gear. Check the brakes after driving through deep water. Apply the brakes moderately to see if they feel normal. If not, apply them gently and frequently until they do. Be extra cautious in your driving.

456

Braking System, Anti-lock Brakes (ABS)

Braking System Design The hydraulic system that operates the brakes has two separate circuits. Each circuit works diagonally across the vehicle (the left-front brake is connected with the right-rear brake, etc.). If one circuit should develop a problem, you will still have braking at two wheels. Brake Wear Indicators All four brakes have audible brake wear indicators. If the brake pads need replacing, you will hear a distinctive, metallic screeching sound when you apply the brake pedal. If you do not have the brake pads replaced, they will screech all the time. It is normal for the brakes to occasionally squeal or squeak when you apply them.

Anti-lock Brakes (ABS) The anti-lock brake system (ABS) helps prevent the wheels from locking up, and helps you retain steering control by pumping the brakes rapidly, much faster than a person can do it. The electronic brake distribution (EBD) system, which is part of the ABS, also balances the front-to-rear braking distribution according to vehicle loading. Youshouldneverpumpthebrakepedal. Let the ABS work for you by always keeping firm, steady pressure on the brake pedal. This is sometimes referred to as ‘‘stomp and steer.’’

You will feel a pulsation in the brake pedal when the ABS activates, and may hear some noise. This is normal: it is the ABS rapidly pumping the brakes. On dry pavement, you will need to press on the brake pedal very hard before the ABS activates. However, you may feel the ABS activate immediately if you are trying to stop on snow or ice.

CONTINUED 457

Anti-lock Brakes (ABS)

ABS Indicator

If this indicator comes on, the anti- lock function of the braking system has shut down. The brakes still work like a conventional system, but without anti-lock. You should have your dealer inspect your vehicle as soon as possible. You will also see a ‘‘CHECK ABS SYSTEM’’ message on the multi- information display (see page 87). If the indicator comes on while driving, test the brakes as instructed on page 560.

If the ABS indicator and the brake system indicator come on together, and the parking brake is fully released, the EBD system may also be shut down. Test your brakes as instructed on page 560. If the brakes feel normal, drive slowly and have your vehicle repaired by your dealer as soon as possible. Avoid sudden hard braking which could cause the rear wheels to lock up and possibly lead to a loss of control. The VSA indicator will come on along with the ABS indicator.

Important Safety Reminders ABS does not reduce the time or distance it takes to stop the vehicle. It only helps with steering control during braking. ABS will not prevent a skid that results from changing direction abruptly, such as trying to take a corner too fast or making a sudden lane change. Always drive at a safe speed for the road and weather conditions. ABS cannot prevent a loss of stability. Always steer moderately when you are braking hard. Severe or sharp steering wheel movement can still cause your vehicle to veer into oncoming traffic or off the road. A vehicle with ABS may require a longer distance to stop on loose or uneven surfaces, such as gravel or snow, than a vehicle without anti- lock.

Overview Ifequipped The collision mitigation braking systemTM (CMBSTM) can assist you when there is a possibility of your vehicle hitting the vehicle in front of you. It is designed to reduce the speed of your vehicle before an unavoidable collision occurs and, if possible, to alert you to a potential collision while there is time to prevent it. Here is a brief description of what the CMBS can do: ● When your speed is above 10 mph

(15 km/h), the CMBS radar sensor in the front grille can sense a vehicle ahead of you. When your vehicle gets too close to the vehicle ahead of you, the system may activate a warning beep, causing automatic application of the brakes, and causing the e- pretensioners to tighten the front seat belts (see page 24).

Collision Mitigation Braking System™ (CMBS™)

RADAR SENSOR

● The CMBS does not activate if the speed difference between the two vehicles is less than 10 mph (15
km/h). CMBS may also not activate if you turn the steering wheel to avoid the collision.

When the CMBS activates, the brake lights also come on.

BRAKE SEAT BELT ACTUATOR e-PRETENSIONERS The CMBS consists of a radar sensor in the front grille, a brake actuator in the engine compartment, an indicator on the instrument panel, seat belt e-pretensioners on the front seats, and an on/off switch on the dashboard.

Collision Mitigation Braking System™ (CMBS™)

Radar Sensor

BOLTS (Do not tamper)

Always keep the radar sensor cover clean. If it gets dirty, clean it with water or a mild detergent. Never use chemical solvents or polishing powder. There are three bolts on the sides of the radar sensor. Do not tamper with these bolts, or you may cause the system to malfunction.

RADAR SENSOR COVER The radar sensor is located under the Acura emblem in the front grille. If the radar sensor cover is covered with mud, dirt, dead leaves, wet snow, etc., or if you put a sticker on it, the CMBS will automatically shut off, and the CMBS indicator on the instrument panel will come on. You will also see a ‘‘CHECK CMBS RADAR SENSOR’’ message on the multi-information display for about 5
seconds.

460

Do not allow anything to impact the radar sensor or the radar sensor cover. If either of these parts receives a strong impact, turn off the system by pressing the CMBS off switch, and have your vehicle checked by a dealer. If the front grille ever needs to be repaired, consult a dealer first. If the radar sensor cover or the radar sensor ever needs to be removed, take your vehicle to a dealer.

When the CMBS is on, the radar sensor constantly scans for vehicles ahead of you. This means that driving on a road with a few or no vehicles could cause a CHECK CMBS RADAR SENSOR message to appear on the multi- information display. This is normal and not a cause for concern.

The radar sensor may not always scan as intended. Here are two examples: ● Your vehicle is tilted because of a

heavy load in the rear or from modifications to the suspension. Do not overload your vehicle (see Carrying Cargo on page 430), and do not make any modifications to the suspension (see Accessories and Modifications on page 428).

● The tires are not correctly

maintained. Always make sure the tire pressures are correct (see page 536), and that the tires are the correct size and in good condition (see Tires on page 536).

Collision Mitigation Braking System™ (CMBS™)

Collision Alarm

If the system senses a likely collision with a vehicle or object ahead of you, it alerts you with an audible and a visual alarm.

The audible alarm is a constant beeping sound; the visual alert is an amber colored BRAKE message that flashes on the multi-information display. If these alarms come on, take the appropriate means to prevent a collision (apply the brakes, change lanes, etc.).

Important Safety Reminder The main purpose of the CMBS is to reduce the severity of injuries caused by an unavoidable collision. While the CMBS may help to alert you and minimize the severity of a collision, it may not activate in every dangerous situation. Even with the CMBS, it is still your responsibility to operate the brake pedal and steering wheel appropriately, according to the driving conditions.

YOUR VEHICLE

SIGN, POLE, etc.

Because of the road condition (curved, winding, etc.) or the state of your vehicle (turning angle, lane position, etc.), CMBS can sometimes mistake a stationary object (light pole, traffic sign, etc.) as a vehicle ahead of you and temporarily operate. This is normal.

468

Vehicle Stability Assist (VSA®), aka Electronic Stability Control (ESC), System

The vehicle stability assist (VSA) system helps to stabilize the vehicle during cornering if the vehicle turns more or less than desired. It also assists you in maintaining traction while accelerating on loose or slippery road surfaces. It does this by regulating the engine's output and by selectively applying the brakes. When VSA activates, you may notice that the engine does not respond to the accelerator in the same way it does at other times. There may also be some noise from the VSA hydraulic system. You will also see the VSA system indicator blink. The VSA system cannot enhance the vehicle's driving stability in all situations and does not control your vehicle's entire braking system. It is still your responsibility to drive and corner at reasonable speeds and to leave a sufficient margin of safety.

VSA Off Indicator

When VSA is off, the VSA off indicator comes on as reminder.

Vehicle Stability Assist (VSA) System Indicator

When VSA activates, you will see the VSA system indicator blink. If this indicator comes on while driving, pull to the side of the road when it is safe, and turn off the engine. Reset the system by restarting the engine. If the VSA system indicator stays on or comes back on while driving, have the VSA system inspected by your dealer. NOTE: The main function of the VSA system is generally known as Electronic Stability Control (ESC). The system also includes a traction control function.

If the indicator does not come on when the ignition switch is turned to the ON (II) position, there may be a problem with the VSA system. Have your dealer inspect your vehicle as soon as possible.

CONTINUED 469

Vehicle Stability Assist (VSA®), aka Electronic Stability Control (ESC), System

You will also see a ‘‘CHECK VSA SYSTEM’’ message on the multi- information display if there is a problem with the VSA system. If the low tire pressure/TPMS indicator comes on, or the multi- information display shows a ‘‘CHECK TPMS SYSTEM’’ message with the indicator flashing (see page 454), the VSA system automatically turns on even if the VSA system is turned off by pressing the VSA OFF switch. If this case, you cannot turn the VSA system off by pressing the VSA OFF switch again. Without VSA, your vehicle will have normal braking and cornering ability, but it will not have VSA traction and stability enhancement.

470

VSA Off Switch

This switch is under the driver's side vent. To turn the VSA system on and off, press and hold it until you hear a beep. When VSA is off, the VSA off indicator comes on as a reminder. Press and hold the switch again. It turns the system back on. With the VSA off, the trailer stability assist function is also turned off (see page 494).

VSA is turned on every time you start the engine, even if you turned it off the last time you drove the vehicle. In certain unusual conditions when your vehicle gets stuck in shallow mud or fresh snow, it may be easier to free it with the VSA temporarily switched off. When the VSA system is off, the traction control system is also off. You should only attempt to free your vehicle with the VSA off if you are not able to free it when the VSA is on. Immediately after freeing your vehicle, be sure to switch the VSA on again. We do not recommend driving your vehicle with the VSA and traction control systems switched off.

Vehicle Stability Assist (VSA®), aka Electronic Stability Control (ESC), System

VSA and Tire Sizes Driving with varying tire or wheel sizes may cause the VSA to malfunction. When replacing tires, make sure they are of the same size and type as your original tires (see page 541). If you install winter tires, make sure they are the same size as those that were originally supplied with your vehicle. Exercise the same caution during winter driving as you would if your vehicle was not equipped with VSA.

Hill Start Assist Your vehicle is equipped with a hill start assist feature to help prevent the vehicle from rolling on steep inclines as you move your foot from the brake pedal to the accelerator. This feature starts operating a few seconds after you are in any drive gear position (when faced uphill) or in reverse (when faced downhill). This feature requires that the vehicle has come to a complete stop before it can work. Hill start assist may not hold a heavily loaded vehicle, such as when your vehicle is connected to a trailer, or prevent your vehicle from rolling downhill on a very steep or slippery slope.

471

Blind Spot Information System (BSI)

U.S.AdvancePackage,Advance PackagewithEntertainment,and CanadianElitePackagemodels The blind spot information system (BSI) is designed to assist you when you are changing lanes.

If the system detects vehicles in adjacent lanes, it automatically illuminates the appropriate indicator to provide assistance when you change lanes. It is not a substitute for visual confirmation that it is safe to change lanes.

472

Failure to visually confirm that it is safe to change lanes before doing so may result in a crash and serious injury or death. Do not rely only on the blind spot information system when changing lanes. Always look in your mirrors, to either side of your vehicle, and behind you for other vehicles before changing lanes.

Blind Spot Information System (BSI)

BSI Operation

ALERT ZONE

A: Approximately 1.6 ft. (0.5m) B: Approximately 10 ft. (3m) C: Approximately 10 ft. (3m) BSI is designed to detect vehicles in specified alert zones adjacent to your vehicle, particularly in harder to see areas commonly known as ‘‘blind spots.’’

When BSI detects a vehicle in an alert zone, a BSI alert indicator comes on near the corresponding outside rearview mirror. While your vehicle is moving forward at a speed between 6 mph (10 km/h) and 100 mph (160 km/h), the BSI alert indicator comes on under either of the following conditions: ● Another vehicle overtakes you,

entering the alert zone from behind, at a speed that differs from your vehicle's speed by no more than 31
mph (50 km/h).

● You pass a vehicle at a speed that

differs from that vehicle's speed by no more than 12 mph (20 km/h). The indicator comes on approximately 2 seconds after the vehicle enters the alert zone.

The system will not alert you to all vehicles in blind spot zones (such as vehicles you have just passed which you should already be aware of) unless it remains in the alert zone for approximately 2 or more seconds. While the system is on, BSI is active whenever the shift lever is in the D or S position.

Blind Spot Information System (BSI)

Important Precautions Like all assistance systems, BSI has limitations. Over-reliance on BSI may result in a collision. Always look in your mirrors, to either side of your vehicle, and behind you for other vehicles before changing lanes.

The system should be turned off when towing a trailer. Due to the added mass and resulting changes in radar coverage, the system cannot operate as intended, and detection of the trailer itself by the radar sensors may cause the BSI alert indicators to illuminate.

Limitations The BSI alert indicators may not illuminate under the following circumstances: ● The speed difference between

your vehicle and a vehicle approaching from behind is greater than 31 mph (50 km/h). ● A vehicle is parked in a side lane. ● The speed difference between

your vehicle and the vehicle you are passing is greater than 6 mph (10 km/h).

● An object not detected by the radar sensors approaches or passes your vehicle.

476

BSI may be adversely affected under the following circumstances: ● When objects such as guard rails,

poles, trees, etc., are detected.

● When an object that doesn't reflect

radio waves well, such as a motorcycle, is in the alert zone.

● A vehicle is behind or approaching

your vehicle while on a curved road.

● When towing a trailer. ● A vehicle is moving from a far lane

to the adjacent lane.

● The system picks up external

electrical interference.

● The rear bumper has been

deformed, or improperly repaired.

Blind Spot Information System (BSI), Active Damper System

Active Damper System Ifequipped The active damper system is always on, constantly adjusting your vehicle's dampers to the best settings for current road conditions along with vehicle speed and handling inputs.

The system uses electrically controlled dampers to enhance handling precision, vehicle composure, tire to road adhesion and rough road ride comfort isolation. The system reacts to inputs from various electronic sensors to give exactly the right amount of suspension damping to provide optimal ride comfort and handling.

Active Damper System Indicator

If there is a problem with the active damper system, the active damper system shuts down and the active damper system indicator on the instrument panel comes on.

If you see this warning indicator and message, have your vehicle checked at your dealer as soon as possible. In this case, your vehicle still has the normal damper function, but it will not have the active damper function.

You will also see the ‘‘CHECK ADS SYSTEM’’ message appear on the multi-information display.

Your vehicle has been designed primarily to carry passengers and their cargo. You can also use it to tow a trailer if you carefully observe the load limits, use the proper equipment, and follow the guidelines in this section. If your vehicle is equipped with the blind spot information system (BSI), do not use it when towing a trailer. For more information see page 478. Break-InPeriod Avoid towing a trailer during your vehicle's first 600 miles (1,000 km) (see page 420). Be sure to read the Off-Highway Driving Guidelines section on page 496 if you plan to tow off paved surfaces.

Towing a Trailer

Your vehicle is equipped with a trailer stability assist to help stabilize the vehicle/trailer combination by reducing the vehicle speed. For more information, see page 494.

Load Limit

Exceeding any load limit or improperly loading your vehicle and trailer can cause a crash in which you can be seriously hurt or killed.

Check the loading of your vehicle and trailer carefully before starting to drive.

TotalTrailerWeight The maximum allowable weight of the trailer and everything in or on it depends on the number of occupants in your vehicle and the type of trailer being towed (see page 486). Towing a trailer that is too heavy can seriously affect your vehicle's handling and performance. It can also damage the engine and drivetrain.

CONTINUED 483

Towing a Trailer

TongueLoad The weight that the tongue of a fully loaded trailer puts on the hitch should be 5 to 15 percent of the total trailer weight for boat trailers, and 8
to 15 percent of total trailer weight for all other trailers. (See page 486
for limits for your towing situation). Too much tongue load reduces front- tire traction and steering control. Too little tongue load can make the trailer unstable and cause it to sway.

484

Gross Vehicle Weight Rating (GVWR) － The maximum allowable weight of the vehicle, all occupants, all accessories, all cargo and the tongue load is 5,952 lbs (2,700 kg). Gross Axle Weight Ratings (GAWR) － The maximum allowable weight of the vehicle, all occupants, all accessories, all cargo, and the tongue load must not exceed 2,888
lbs (1,310 kg) on the front axle, and 3,175 lbs (1,440 kg) on the rear axle. Gross Combined Weight Rating (GCWR) － The maximum allowable weight of the fully loaded vehicle and trailer is 10,053 lbs (4,560 kg) with the proper hitch. The GCWR must be reduced 2 percent for every 1,000
feet (305 meters) of elevation.

Estimating Loads The best way to confirm that all loads are within limits is to check them at a public scale. For public scales in your area, check your local phone book, or contact your trailer dealer or rental agency for assistance. To help ensure a safe drive to a scale, or if you cannot get to a public scale, we recommend that you estimate your total trailer weight and tongue load as described. ToEstimatetheTotalTrailerWeight Add the weight of your trailer (as quoted by the manufacturer) with everything in or on the trailer. Then check the tables on page 486 to make sure you do not exceed the limit for your conditions.

ToEstimatetheTongueLoad 1. Park the vehicle on level ground. 2. Measure and record the distance from the ground to the bottom of the trailer hitch.

3. Connect the fully loaded trailer to

the hitch.

4. Measure again from the ground to the same spot on the bottom of the hitch.

5. Subtract the second measurement from the first measurement, then refer to the following table.

Checking Loads To accurately check your loads at the public scale, the vehicle and trailer should be fully loaded, and all occupants should stay in the vehicle while the attendant watches the scale.

1. Check the front gross axle weight.

Limit: 2,888 lbs (1,310 kg)

Towing a Trailer

2. Check the gross vehicle weight.

Limit: 5,952 lbs (2,700 kg)

3. Check the rear gross axle weight.

Limit: 3,175 lbs (1,440 kg)

4. If you cannot weigh the rear axle

directly, you can calculate the rear gross axle weight by subtracting the weight in step 1 from the weight in step 2. Limit: 3,064 lbs (1,390 kg)

5. Check the gross combined weight.

Limit: 10,053 lbs (4,560 kg) Remember, maximum gross combined weight should be decreased 2% for every 1,000 feet (305 meters) of elevation.

6. Check the weight of the hitched trailer. Write this number down.

7. Check the weight of the unhitched

trailer. Limit: See page 486.

8. Calculate the tongue load. Subtract

the weight in step 6 from the weight in step 7. Limit: See page 486. Recommended: see page 483. Range: 5-15% for boat trailers 8-15% for other trailers

Towing Equipment and Accessories Towing generally requires a variety of supplemental equipment. To ensure the best quality, we recommend that you purchase Acura equipment whenever possible. Your dealer offers a trailer package that includes a hitch, a ball mount, and a wiring harness. Discuss any additional needs with your trailer sales or rental agency, and make sure all equipment is properly installed, maintained, and also meets state, federal, province, and local regulations.

488

Hitch We strongly recommend that you have your dealer install a class 3
hitch. Using non-Acura equipment may result in serious damage to your vehicle. Read the trailer manufacturer's instructions, and select the appropriate draw bar for the height of the trailer you will be towing. WeightDistributingHitch A weight distributing hitch is not recommended for use with your vehicle, as an improperly adjusted weight distributing hitch may reduce handling, stability, and braking performance.

TrailerBrakes Acura recommends that any trailer with a total trailer weight of 1,000 lbs (450 kg) or more has its own brakes. There are two common types of trailer brakes: surge and electric. Surge brakes are common for boat trailers, since the brakes will get wet. If you choose electric brakes, be sure they are electronically actuated. Do not attempt to tap into your vehicle's hydraulic system. No matter how successful it may seem, any attempt to attach trailer brakes to your vehicle's hydraulic system will lower braking effectiveness and create a potential hazard. See your trailer dealer or rental agency for more information on installing electric brakes.

Towing a Trailer

A 4-pin gray connector is available as an option at your dealer. This connector has all of the circuits required to install most electric trailer brake controllers. A jumper harness to adapt your electric trailer brake controller to the vehicle is included with the optional Acura Genuine trailer hitch kit. To obtain a connector and a trailer hitch kit, see your dealer. Have a qualified mechanic install your trailer brake controller following the trailer brake controller manufacturer's instructions. Failure to properly install the trailer brake controller may increase the distance it takes for you to stop your vehicle when towing a trailer.

SpareTires When towing a trailer, we recommend that you carry a full-size spare wheel and tire for your vehicle and trailer. See page 541 for proper tire size, page 547 for how to store a full size wheel and tire, and page 547
for information on changing a flat tire. Remember to unhitch the trailer before changing a flat. Ask your trailer sales or rental agency where and how to store the trailer's spare tire.

SafetyChains Always use safety chains when you tow a trailer. Make sure the chains are secured to the trailer and hitch, and that they cross under the tongue and can catch the trailer if it becomes unhitched. Leave enough slack to allow the trailer to turn corners easily, but do not let the chains drag on the ground. SwayControl This device is recommended if your trailer tends to sway. Your trailer maker can tell you what kind of sway control you need and how to install it. TrailerMirrors Many states and provinces require special exterior mirrors when towing a trailer. Even if they don't, you should install special mirrors if you cannot clearly see behind you, or if the trailer creates a blind spot.

TAILLIGHTS

Trailer lights and equipment must comply with federal, state, province, and local regulations. Check trailer light requirements for the areas where you plan to tow, and use only equipment designed for your vehicle. Your vehicle is equipped with a connector to install an optional trailer lighting connector that mates with your vehicle. You can get this optional connector from your dealer.

Refer to the above illustration for wiring information. We recommend that you have your dealer install an Acura wiring harness and converter. This harness has been designed for your vehicle.

Towing a Trailer

If you use a non-Acura trailer lighting harness and converter, you can get the mating connector and pins that mate with the connector in your vehicle from your dealer. Since lighting and wiring vary with trailer type and brand, you should also have a qualified mechanic install a suitable connector between the vehicle and the trailer.

● The lights and brakes on your

vehicle and the trailer are working properly.

● Your vehicle tires and spare are in

good condition and properly inflated.

● The trailer tires and spare are in

good condition and inflated as recommended by the trailer maker.

Driving Safely With a Trailer The added weight, length, and height of a trailer will affect your vehicle's handling and performance, so driving with a trailer requires some special driving skills and techniques. For your safety and the safety of others, take time to practice driving maneuvers before heading for the open road, and follow the guidelines in this section.

Towing a Trailer

Pre-Tow Checklist When preparing to tow, and before driving away, be sure to check the following: ● The vehicle has been properly

serviced, and the suspension and the cooling system are in good operating condition.

● The trailer has been properly

serviced and is in good condition.

● All weights and loads are within

limits.

● The hitch, safety chains, and any

other attachments are secure.

● All items on and in the trailer are properly secured and cannot shift while you drive.

TowingSpeedsandGears Drive slower than normal in all driving situations, and obey posted speed limits for vehicles with trailers. Use the D position when towing a trailer on level roads. See ‘‘Drivingon Hills’’ for additional gear information. When towing a fixed-sided trailer (e. g., camper), do not exceed 55 mph (88 km/h). At higher speeds, the trailer may sway or affect vehicle handling.

If the automatic transmission fluid temperature increases and exceeds the specified limit, the A/T temperature indicator comes on (see page 70). You will also see a ‘‘A/T TEMP HIGH’’ message on the multi- information display. MakingTurnsandBraking Make turns more slowly and wider than normal. The trailer tracks a smaller arc than your vehicle, and it can hit or run over something the vehicle misses. Allow more time and distance for braking. Do not brake or turn suddenly as this could cause the trailer to jackknife or turn over.

Towing a Trailer

DrivingonHills When climbing hills, closely watch your temperature gauge. If it nears the red (Hot) mark, turn the air conditioning off, reduce speed and, if necessary, pull to the side of the road to let the engine cool. If you must stop when facing uphill, use the foot brake or parking brake. Do not try to hold the vehicle in place by pressing on the accelerator, as this can cause the automatic transmission to overheat. When driving down hills, reduce your speed and shift down to S position, or use the paddle shifters to lower gear (3, or 2) in the S position. When towing a trailer, do not ‘‘ride’’ the brakes, and remember, it takes longer to slow down and stop when towing a trailer.

Towing a Trailer, Trailer Stability Assist

RetrievingaBoat If the vehicle tires slip when retrieving a boat from the water, keep the transmission in the D position and do not use the sequential sport shift mode. This prevents the transmission damage. Towing Your Vehicle Your vehicle is not designed to be towed behind a motor home. If your vehicle needs to be towed in an emergency, see page 568.

Trailer Stability Assist Your vehicle is equipped with trailer stability assist function. This function works on the same sensors as the vehicle stability assist (VSA) system. This function helps to stabilize the vehicle/trailer combination when the trailer severely sways or oscillates. For more information on the VSA system, see page 469. If the function detects vehicle/trailer instability, it checks if the swaying is caused by the trailer, and if the trailer swaying or oscillation is increasing. The vehicle/trailer combination is more affected by crosswinds, buffeting, and improper tongue load. These conditions can make the trailer unstable, and cause it to sway.

HandlingCrosswindsandBuffeting Crosswinds and air turbulence caused by passing trucks can disrupt your steering and cause the trailer to sway. When being passed by a large vehicle, keep a constant speed, and steer straight ahead. Do not try to make quick steering or braking corrections. BackingUp Always drive slowly and have someone guide you when backing up. Grip the bottomof the steering wheel, then turn the wheel to the left to get the trailer to move to the left. Turn the wheel to the right to move the trailer to the right. Parking Follow all normal precautions when parking, including putting the transmission in Park and firmly setting the parking brake. Also, place wheel chocks at each of the trailer's tires.

494

Under these conditions, trailer stability assist begins to stabilize the vehicle/trailer combination by reducing the vehicle speed. The control unit sends signals to selectively apply the brakes and regulate the engine output. The brake lights of your vehicle will be turned on automatically by the system even if you do not keep the pressure on the brake pedal. When the brakes are applied, the trailer's brake lights come on along with the vehicle brake lights. When the trailer stability assist activates, you will see the VSA system indicator blink. There may also be some noise from the VSA hydraulic system.

Trailer stability assist cannot prevent a loss of control. Always reduce the vehicle speed and steer firmly. Do not brake suddenly or make quick steering motion. It could cause the trailer to jackknife or turn over and the system becomes ineffective. Trailer stability assist cannot prevent swaying that can occur in crosswinds and in normal and emergency driving maneuvers. It helps only to stabilize the vehicle/trailer combination in these conditions, after the oscillation becomes severe. Trailer stability assist will also be ineffective while driving at high speed or towing a trailer with a high center of gravity. Always obey the recommended speed limits for towing a trailer, see page 493.

Trailer Stability Assist

Trailer Stability Assist Failure

The control unit monitors the VSA circuitry and the braking system. If there is a problem with the brake lighting system, the trailer stability assist function shuts down and the ‘‘CHECK TRAILER STABILITY ASSIST’’ message appears on the multi-information display. If you see this message, have your vehicle checked at your dealer as
