Universal Home Remote System See Radio Frequency Statement on page 8‑18 for information regarding Part 15 of the Federal Communications Commission (FCC) Rules and RSS-210/211 of Industry and Science Canada. Universal Home Remote System Operation (With Three Round LED)


This vehicle may have the Universal Home Remote System. If there are three round Light Emitting Diode (LED) indicator lights above the Universal Home Remote buttons, follow the instructions below.


This system provides a way to replace up to three remote control transmitters used to activate devices such as garage door openers, security systems, and home automation devices. Do not use this system with any garage door opener that does not have the stop and reverse feature. This includes any garage door opener model manufactured before April 1, 1982. Read the instructions completely before attempting to program the transmitter. Because of the steps involved, it may be helpful to have another person assist with programming the transmitter. Be sure to keep the original remote control transmitter for use in other vehicles, as well as, for future programming. Only the original remote control transmitter is needed for Fixed Code programming. The programmed buttons should be erased when the vehicle is sold or the lease ends. See “Erasing Universal Home Remote Buttons” later in this section. Park the vehicle outside of the garage when programming a garage door. Be sure that people and objects are clear of the garage door or gate that is being programmed.

garage door should move, confirming that programming is successful and complete.


To program another Rolling Code device such as an additional garage door opener, a security device, or home automation device, repeat Steps 1 through 5, choosing a different function button in Step 3 than what was used for the garage door opener.


If these instructions do not work, the garage door opener is probably a Fixed Code unit. Follow the Programming instructions that follow for a Fixed Code garage door opener. Programming Universal Home Remote — Fixed Code For questions or help programming the Universal Home Remote System, call 1-866-572-2728 or go to learcar2u.com. Most garage door openers sold before 1996 are Fixed Code units. Programming a garage door opener involves time-sensitive actions, so read the entire procedure before starting. Otherwise, the device will time out and the procedure will have to be repeated.


3-71


To program up to three devices:


The garage door opener receiver (motor head unit) could also have a row of dip switches that can be used when programming the Universal Home Remote. If the total number of switches on the motor head and hand held transmitter are different, or if the dip switch settings are different, use the dip switch settings on the motor head unit to program the Universal Home Remote. The motor head dip switch settings can also be used when the original hand held transmitter is not available.


1. To verify that the garage door opener is a Fixed Code unit, remove the battery cover on the hand held transmitter supplied by the manufacturer of the garage door opener motor. If there are a row of dip switches similar to the graphic above, the garage door opener is a Fixed Code unit. If you do not see a row of dip switches, return to the previous section for Programming Universal Home Remote – Rolling Code. Your hand held transmitter can have between eight to 12 dip switches depending on the brand of transmitter.


3-72


Example of Eight Dip Switches with Two Positions


2. Write down the eight to 12 switch settings from left


to right as follows: . When a switch is in the up position, write “Left.” . When a switch is in the down position, write


“Right.” If a switch is set between the up and down position, write “Middle.” The switch settings written down in Step 2 now become the button strokes to be entered into the Universal Home Remote in Step 4. Be sure to enter the switch settings written down in Step 2, in order from left to right, into the Universal Home Remote, when completing Step 4.


3. From inside your vehicle, first firmly press all three buttons at the same time for about three seconds. Release the buttons to put the Universal Home Remote into programming mode.

Roof Rack System


{ WARNING:


If something is carried on top of the vehicle that is longer or wider than the roof rack— like paneling, plywood, or a mattress— the wind can catch it while the vehicle is being driven. The item being carried could be violently torn off, and this could cause a collision, and damage the vehicle. Never carry something longer or wider than the roof rack on top of the vehicle unless using a GM Certified accessory carrier.


For vehicles with a roof rack, the rack can be used to load items. For roof racks that do not have crossrails included, GM Certified crossrails can be purchased as an accessory. See your dealer/retailer for additional information. Notice: Loading cargo on the roof rack that weighs more than 91 kg (200 lbs) or hangs over the rear or sides of the vehicle may damage the vehicle. Load cargo so that it rests evenly between the crossrails, making sure to fasten cargo securely.


To prevent damage or loss of cargo when driving, check to make sure crossrails and cargo are securely fastened. Loading cargo on the roof rack will make the vehicle’s center of gravity higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or abrupt maneuvers, otherwise it may result in loss of control. If driving for a long distance, on rough roads, or at high speeds, occasionally stop the vehicle to make sure the cargo remains in its place. Do not exceed the maximum vehicle capacity when loading the vehicle. For more information on vehicle capacity and loading, see Loading the Vehicle on page 5‑29 .


If small heavy objects are placed on the roof, cut a piece of 3/8 inch plywood to fit inside the crossrails and siderails to spread the load. Tie the plywood to the siderail supports. Tie the load and secure it to the crossrails or the siderail supports. Use the crossrails only to keep the load from sliding. To move a crossrail, lift the release lever up, on both sides of the rail. Then slide the crossrail to the desired position balancing the force side to side. Press the release lever down on both sides of the rail, down to tighten it. Try to slide the crossrail back and forth slightly to make sure it is tight.


3-77


.


To carry long items, move the crossrails as far apart as possible. Tie the load to the crossrails and the siderails or siderail supports. Also tie the load to the bumpers, but do not tie the load so tightly that the crossrails or siderails are damaged.


. After moving a crossrail, be sure it is securely


locked into the siderail.


A Center High-Mounted Stoplamp (CHMSL) is located above the rear window glass. Make sure items loaded on the roof of the vehicle do not block or damage the CHMSL. Rear Seat Armrest Vehicles with a rear seat armrest have two cupholders. Pull the armrest down from the rear seatback to access the cupholders. Cargo Management System For vehicles with a cargo management system, it is located in the bed of the truck. The system contains three rails located on the front and sides of the bed. The system has four adjustable cargo tie-downs, that can be placed on the upper and lower slides of the rail.


3-78


To adjust a tie-down, pull the locator pin out and move the tie-down to another location making sure the locator pin lines up with a locator hole on the rail. The tie-down pin may not be installed correctly if the pin does not line up, turn it over and reinstall. The tie-down will not move when the pin is completely installed. The maximum load for each rail is 500 lbs (227 kg). The rails are notched at each end which allows the tie-downs to be removed and placed on another rail. To remove, pull the locator pin out and slide the tie-down to the end of the rail and pull back.


To remove or install cargo tie-downs at the front of the bed, slide the corner cap towards the center of the bed to expose the rail notches. To remove the corner cap, pull either edge away from the rail. To remove the system, loosen the toggle bolts on each rail until they can be removed from the bed of the truck. To replace the system, place the toggle bolts and rails into their original locations and tighten them to a torque setting of 12.5 ft lbs (17 Y). If the system is removed to install a bed liner, make sure there is no bed liner material in the installation points. Notice: If cargo is tied down using the horizontal slots on the top of the pickup box, the box could be damaged. Using the horizontal slots on the top of the pickup box for tie-down locations may cause damage to the pickup box and would not be covered by the vehicle warranty. Only use the tie-down loops if the vehicle does not have the cargo management system.


Sunroof On vehicle with a power sliding sunroof, the ignition needs to be turned to RUN, or the Retained Accessory Power (RAP) must be activated to open or close the sunroof. When RAP is active, the sunroof will work for 10 minutes after the ignition is turned off, or until the driver's door is opened. See Retained Accessory Power (RAP) on page 3‑23 for more information. Do not leave the sunroof open for long periods of time while the vehicle is not in use. Debris can collect in the tracks and damage the sunroof operation and plug the water draining system. Extended Cab

Daytime Running Lamps (DRL) Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. Fully functional daytime running lamps are required on all vehicles first sold in Canada. The DRL system comes on when the following conditions are met:


The ignition is on. The exterior lamps control is in AUTO. The engine is running. The light sensor determines it is daytime.


When the DRL system is on, only the DRL lamps are on. The taillamps, sidemarker, instrument panel lights, and other lamps will not be on. When it begins to get dark, the automatic headlamp system switches from DRL to the headlamps. To turn off the DRL lamps, turn the exterior lamps control to the OFF position and then release. For vehicles first sold in Canada, the transmission must be in the P (Park) position, before the DRL lamps can be turned off.


4-12


Automatic Headlamp System When it is dark enough outside, the automatic headlamp system turns on the headlamps at the normal brightness, along with the taillamps, sidemarker, parking lamps, and the instrument panel lights. The radio lights will also be dim. To turn off the automatic headlamp system, turn the exterior lamps switch to the off position and then release it. For vehicles first sold in Canada, the transmission must be in the P (Park) position, before the automatic headlamp system can be turned off. The vehicle has a light sensor located on the top of the instrument panel in the defroster grille that regulates when the automatic headlamps turn on. Do not cover the sensor or the headlamps will come on whenever the ignition is on. The system may also turn on the headlamps when driving through a parking garage or heavy overcast weather. This is normal. There is a delay in the transition between the daytime and nighttime operation of the Daytime Running Lamps (DRL) and the automatic headlamp systems so that driving under bridges or bright overhead street lights does not affect the system. The DRL and automatic headlamp system is only affected when the light sensor detects a change in lighting lasting longer than the delay.


If the vehicle is started in a dark garage, the automatic headlamp system comes on immediately. Once the vehicle leaves the garage, it takes approximately one minute for the automatic headlamp system to change to DRL if it is bright enough outside. During that delay, the instrument panel cluster may not be as bright as usual. Make sure the instrument panel brightness control is in the full bright position. See Instrument Panel Brightness on page 4‑14. To idle the vehicle with the automatic headlamp system off, turn the control to the off position. The headlamps will also stay on after you exit the vehicle. This feature can be programmed using the Driver Information Center (DIC), if equipped. See DIC Vehicle Customization (With DIC Buttons) on page 4‑73 . If the vehicle is not equipped with DIC buttons, exit lighting is automatic. When it is dark enough outside, the exterior lamps remain on for 30 seconds after the ignition is moved from ON/RUN to LOCK/OFF. For vehicles without a radio, the instrument panel light remains on for 30 seconds with the driver's door closed. For vehicles with a radio, the instrument panel light remains on for 10 minutes with the driver's door closed. See Retained Accessory Power (RAP) on page 3‑23. The regular headlamp system can be turned on when needed.


Puddle Lamps If the vehicle has puddle lamps, they come on when the unlock button on the Remote Keyless Entry (RKE) Transmitter is pressed. The lamps time out or turn off once the engine is started. Fog Lamps For vehicles with fog lamps, the control is located next to the exterior lamps control on the instrument panel, to the left of the steering column. The ignition must be in the ON/RUN position for the fog lamps to come on. # (Fog Lamps): Press to turn the fog lamps on or off. A light will come on in the instrument panel cluster. When the fog lamps are turned on, the parking lamps automatically turn on. When the headlamps are changed to high-beam, the fog lamps also go off. When the high-beam headlamps are turned off, the fog lamps will come on again. Some localities have laws that require the headlamps to be on along with the fog lamps.

Electric Power Management The vehicle has Electric Power Management (EPM) that estimates the battery's temperature and state of charge. It then adjusts the voltage for best performance and extended life of the battery. When the battery's state of charge is low, the voltage is raised slightly to quickly bring the charge back up. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gage or a voltage display on the Driver Information Center (DIC), you may see the voltage move up or down. This is normal. If there is a problem, an alert will be displayed. The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads. A high electrical load occurs when several of the following are on, such as: headlamps, high beams, fog lamps, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets.


EPM works to prevent excessive discharge of the battery. It does this by balancing the generator's output and the vehicle's electrical needs. It can increase engine idle speed to generate more power, whenever needed. It can temporarily reduce the power demands of some accessories. Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, a Driver Information Center (DIC) message might be displayed, such as BATTERY SAVER ACTIVE, BATTERY VOLTAGE LOW, or LOW BATTERY. If this message is displayed, it is recommended that the driver reduce the electrical loads as much as possible. See DIC Warnings and Messages on page 4‑63 . Battery Run-Down Protection This feature shuts off the dome and reading lamps, if they are left on for more than 10 minutes after the ignition is turned off. The cargo lamp shuts off after 20 minutes. This prevents the battery from running down.


4-16


Accessory Power Outlet(s) Accessory power outlets can be used to connect auxiliary electrical equipment, such as a cellular telephone. The vehicle may have two accessory power outlets located below the climate control system, or may have one accessory power outlet and one cigarette lighter. The cigarette lighter is designed to fit only in the receptacle closest to the driver. There may be another accessory power outlet in the rear cargo area. If the vehicle has a floor console, there is an accessory power outlet inside the storage bin and one on the rear of the floor console. To use an accessory power outlet, remove the protective cap. When not in use, always cover the accessory power outlet with the protective cap. Notice: Leaving electrical equipment plugged in for an extended period of time while the vehicle is off will drain the battery. Power is always supplied to the outlets. Always unplug electrical equipment when not in use and do not plug in equipment that exceeds the maximum 20 ampere rating.


Certain power accessory plugs may not be compatible to the accessory power outlet and could result in blown vehicle or adapter fuses. If you experience a problem, see your dealer/retailer for additional information on the accessory power plugs. The accessory power outlets are powered, even when the ignition is in LOCK/OFF. Continuing to use power outlets while the ignition is in LOCK/OFF may cause the vehicle's battery to run down. Notice: Adding any electrical equipment to the vehicle can damage it or keep other components from working as they should. The repairs would not be covered by the vehicle warranty. Do not use equipment exceeding maximum amperage rating of 20 amperes. Check with your dealer/retailer before adding electrical equipment. When adding electrical equipment, be sure to follow the proper installation instructions included with the equipment. Notice: Improper use of the power outlet can cause damage not covered by the vehicle warranty. Do not hang any type of accessory or accessory bracket from the plug because the power outlets are designed for accessory power plugs only.

0 (Defrost): This mode removes fog or frost from the windshield more quickly. Air is directed to the windshield and side window vents, with some directed to the floor vents. In this mode, the system automatically forces outside air into the vehicle and runs the air conditioning compressor unless the outside temperature is close to freezing. The recirculation mode cannot be selected while in the defrost mode. The passenger temperature control cannot be activated while in defrost mode. If the PASS button is pressed, the button indicator flashes three times and will not work. If the passenger temperature buttons are adjusted, the driver temperature indicator changes. The passenger temperature will not be displayed. If vent, bi-level, or floor mode is selected again, the climate control system displays the previous temperature settings. Do not drive the vehicle until all the windows are clear. # (Air Conditioning): Press to turn the air conditioning (A/C) compressor on and off. An indicator light comes on to show that the air conditioning is on.


If this button is pressed when the air conditioning compressor is unavailable due to outside conditions, the indicator flashes three times and then turns off. If the air conditioning is on and the outside temperature drops below a temperature which is too cool for air conditioning to be effective, the air conditioning light turns off to show that the air conditioning mode has been canceled. On hot days, open the windows long enough to let hot inside air escape. This helps to reduce the time it takes for the vehicle to cool down. It also helps the system to operate more efficiently. The air conditioning system removes moisture from the air, so a small amount of water might drip under the vehicle while idling or after turning off the engine. This is normal. @ (Recirculation): Press to turn the recirculation mode on. An indicator light comes on to show that the recirculation is on. This mode recirculates and helps to quickly cool the air inside the vehicle. It can be used to help prevent outside air and odors from entering the vehicle.


4-25


The recirculation mode cannot be used with floor, defog, or defrost modes. If recirculation is selected with one of those modes, the indicator light flashes three times and then turns off. The air conditioning compressor also comes on when this mode is activated. While in recirculation mode the windows may fog when the weather is cold and damp. To clear the fog, select either the defog or defrost mode and increase the fan speed. The recirculation mode can be turned off by pressing the outside air button, or by turning off the ignition. ; (Outside Air): Press to turn the outside air mode on. An indicator light on the button comes on to show that outside is on. When selected, air from outside the vehicle circulates throughout the vehicle. The outside air mode can be used with all modes, but it cannot be used with the recirculation mode.


Rear Window Defogger The rear window defogger uses a warming grid to remove fog from the rear window. < (Rear Window Defogger): For vehicles with this feature, press to turn the defogger on or off. It automatically turns off several minutes after it has been activated. The defogger can also be turned off by turning the engine off. Do not drive the vehicle until all the windows are clear. Notice: Do not use a razor blade or sharp object to clear the inside rear window. Do not adhere anything to the defogger grid lines in the rear glass. These actions may damage the rear defogger. Repairs would not be covered by your warranty. Heated Mirror : For vehicles with heated outside rearview mirrors, the mirrors heat to help clear fog or frost from the surface of the mirror when the rear window defog button is pressed. See Outside Power Mirrors on page 3‑57.

Sensors


The solar sensor, located in the defrost grille, in the middle of the instrument panel, monitors the solar heat. Do not cover the solar sensor or the system will not work properly.


The interior temperature sensor, located in the headliner, measures the temperature of the air inside the vehicle.


There is also an exterior temperature sensor located behind the front grille. This sensor reads the outside air temperature and helps maintain the temperature inside the vehicle. Any cover on the front of the vehicle could cause a false reading in the displayed temperature. The climate control system uses the information from these sensors to maintain your comfort setting by adjusting the outlet temperature, fan speed, and the air delivery mode. The system may also supply cooler air to the side of the vehicle facing the sun. The recirculation mode will also be used as needed to maintain cool outlet temperatures.


4-27


Outlet Adjustment Use the air outlets located in the center and on the side of the instrument panel to direct the airflow. Use the thumbwheels near the air outlets to open or close off the airflow. Operation Tips . Clear away any ice, snow, or leaves from air inlets


at the base of the windshield that could block the flow of air into the vehicle.


. Keep the path under the front seats clear of


objects to help circulate the air inside of the vehicle more effectively.


. Use of non‐GM approved hood deflectors can


adversely affect the performance of the system. Check with your dealer/retailer before adding equipment to the outside of the vehicle.


Warning Lights, Gages, and Indicators Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to the warning lights and gages could prevent injury. Warning lights come on when there might be or there is a problem with one of the vehicle's functions. Some warning lights come on briefly when the engine is started to indicate they are working. Gages can indicate when there might be or there is a problem with one of the vehicle's functions. Often gages and warning lights work together to indicate a problem with the vehicle. When one of the warning lights comes on and stays on while driving, or when one of the gages shows there could be a problem, check the section that explains what to do. Follow this manual's advice. Waiting to do repairs can be costly and even dangerous.

Charging System Light


Voltmeter Gage


This light comes on briefly when the ignition key is turned to START, but the engine is not running, as a check to show it is working.


For vehicles with a voltmeter gage, this gage indicates the battery voltage when the ignition is turned on.


If it does not, have the vehicle serviced by your dealer/retailer. The light should go out once the engine starts. If it stays on, or comes on while driving, there could be a problem with the charging system. A charging system message in the Driver Information Center (DIC) can also appear. See DIC Warnings and Messages on page 4‑63 for more information. This light could indicate that there are problems with a generator drive belt, or that there is an electrical problem. Have it checked right away. If the vehicle must be driven a short distance with the light on, turn off accessories, such as the radio and air conditioner.


When the ignition is on, this gage indicates the battery voltage. When the engine is running, this gage shows the condition of the charging system. The gage can transition from a higher to lower or a lower to higher reading. This is normal. If the vehicle is operating outside the normal operating range, the charging system light comes on. See Charging System Light on page 4‑36 for more information. The voltmeter gage may also read lower when in fuel economy mode. This is normal.


4-36


Readings outside the normal operating range can also occur when a large number of electrical accessories are operating in the vehicle and the engine is left idling for an extended period. This condition is normal since the charging system is not able to provide full power at engine idle. As engine speeds are increased, this condition should correct itself as higher engine speeds allow the charging system to create maximum power. The vehicle can only be driven for a short time with the readings outside the normal operating range. If the vehicle must be driven, turn off all accessories, such as the radio and air conditioner. Readings outside the normal operating range indicate a possible problem in the electrical system. Have the vehicle serviced as soon as possible.


Brake System Warning Light With the ignition on, the brake system warning light comes on when the parking brake is set. If the vehicle is driven with the parking brake engaged, a chime sounds when the vehicle speed is greater than 5 mph (8 km/h). The vehicle's hydraulic brake system is divided into two parts. If one part is not working, the other part can still work and stop the vehicle. For good braking, both parts need to be working well. If the warning light comes on and a chime sounds there could be a brake problem. Have the brake system inspected right away. This light can also come on due to low brake fluid. See Brakes on page 6‑39 for more information.


4-37


If the light comes on while driving, pull off the road and stop carefully. The pedal might be harder to push or might go closer to the floor. It can take longer to stop. If the light is still on, have the vehicle towed for service. See Towing Your Vehicle on page 5‑43. Antilock Brake System (ABS) Warning Light


For vehicles with the Antilock Brake System (ABS), this light comes on briefly when the engine is started.


If it does not, have the vehicle serviced by your dealer/ retailer. If the system is working normally the indicator light then goes off.


United States


Canada


This light comes on briefly when the ignition key is turned to ON/RUN. If it does not come on then, have it fixed so it is ready to warn if there is a problem.


{ WARNING:


The brake system might not be working properly if the brake system warning light is on. Driving with the brake system warning light on can lead to a crash. If the light is still on after the vehicle has been pulled off the road and carefully stopped, have the vehicle towed for service.


4-38


If the ABS light stays on, turn the ignition off. If the light comes on while driving, stop as soon as it is safely possible and turn the ignition off. Then start the engine again to reset the system. If the ABS light stays on, or comes on again while driving, the vehicle needs service. If the regular brake system warning light is not on, the vehicle still has brakes, but not antilock brakes. If the regular brake system warning light is also on, the vehicle does not have antilock brakes and there is a problem with the regular brakes. See Brake System Warning Light on page 4‑37. For vehicles with a Driver Information Center (DIC), see DIC Warnings and Messages on page 4‑63 for all brake related DIC messages.


StabiliTrak® Indicator Light


For vehicles with the StabiliTrak® system, this light comes on briefly while starting the engine.


If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light then goes off. If the light comes on and stays on while driving, there could be a problem with the StabiliTrak® system and the vehicle might need service. When this warning light is on, the StabiliTrak® system is off and does not limit wheel spin. The light flashes if the system is active and is working to assist the driver with directional control of the vehicle in difficult driving conditions. See StabiliTrak® System on page 5‑6 for more information.

Engine Coolant Temperature Gage


Tire Pressure Light


For vehicles with a tire pressure monitoring system, this light comes on briefly when the engine is started. It provides information about tire pressures and the Tire Pressure Monitoring System. When the Light is On Steady This indicates that one or more of the tires is significantly underinflated. A tire pressure message in the Driver Information Center (DIC), can accompany the light. See Driver Information Center (DIC) on page 4‑49 for more information. Stop and check the tires as soon as it is safe to do so. If underinflated, inflate to the proper pressure. See Inflation - Tire Pressure on page 6‑72
for more information.


United States


Canada


This gage shows the engine coolant temperature. It also provides an indicator of how hard the vehicle is working. During a majority of the operation, the gage will read 210°F (100°C) or less. If the vehicle is pulling a load or going up hills, it is normal for the temperature to fluctuate and go over the 235°F (113°C) mark. However, if the gage reaches the 260°F (125°C) mark, it indicates that the cooling system is working beyond its capacity. See Engine Overheating on page 6‑34.


4-40


When the Light Flashes First and Then is On Steady This indicates that there may be a problem with the Tire Pressure Monitor System. The light flashes for about a minute and stays on steady for the remainder of the ignition cycle. This sequence repeats with every ignition cycle. See Tire Pressure Monitor Operation on page 6‑76 for more information. Malfunction Indicator Lamp Check Engine Light A computer system called OBD II (On-Board Diagnostics-Second Generation) monitors operation of the fuel, ignition, and emission control systems. It ensures that emissions are at acceptable levels for the life of the vehicle, helping to produce a cleaner environment.


This light should come on when the ignition is on, but the engine is not running, as a check to show it is working. If it does not, have the vehicle serviced by your dealer/retailer.


If the check engine light comes on and stays on, while the engine is running, this indicates that there is an OBD II problem and service is required. Malfunctions often are indicated by the system before any problem is apparent. Being aware of the light can prevent more serious damage to the vehicle. This system assists the service technician in correctly diagnosing any malfunction. Notice: If the vehicle is continually driven with this light on, after a while, the emission controls might not work as well, the vehicle's fuel economy might not be as good, and the engine might not run as smoothly. This could lead to costly repairs that might not be covered by the vehicle warranty.


4-41


If the light continues to flash, when it is safe to do so, stop the vehicle. Find a safe place to park the vehicle. Turn the key off, wait at least 10 seconds, and restart the engine. If the light is still flashing, follow the previous steps and see your dealer/retailer for service as soon as possible. Light On Steady : An emission control system malfunction has been detected on the vehicle. Diagnosis and service might be required. An emission system malfunction might be corrected by doing the following:


. Make sure the fuel cap is fully installed. See Filling


the Tank on page 6‑11 . The diagnostic system can determine if the fuel cap has been left off or improperly installed. A loose or missing fuel cap allows fuel to evaporate into the atmosphere. A few driving trips with the cap properly installed should turn the light off.


Notice: Modifications made to the engine, transmission, exhaust, intake, or fuel system of the vehicle or the replacement of the original tires with other than those of the same Tire Performance Criteria (TPC) can affect the vehicle's emission controls and can cause this light to come on. Modifications to these systems could lead to costly repairs not covered by the vehicle warranty. This could also result in a failure to pass a required Emission Inspection/Maintenance test. See Accessories and Modifications on page 6‑4. This light comes on during a malfunction in one of two ways: Light Flashing : A misfire condition has been detected. A misfire increases vehicle emissions and could
