Check engine

Your vehicle is equipped with a computer that monitors the engine’s emission control system. This system is commonly known as the On Board Diagnostics System (OBD

CHECK

ENGINE

Instrumentation

II). This OBD II system protects the environment by ensuring that your vehicle continues to meet government emission standards. The OBD II system also assists the service technician in properly servicing your vehicle.

The Check Engine indicator light illuminates when the ignition is first turned to the ON position to check the bulb. If it comes on after the engine is started, one of the engine’s emission control systems may be malfunctioning. The light may illuminate without a driveability concern being noted. The vehicle will usually be drivable and will not require towing.

What you should do if the check engine light illuminates

Light turns on solid:

This means that the OBD II system has detected a malfunction. Temporary malfunctions may cause your Check Engine light to

illuminate. Examples are:

1. The vehicle has run out of fuel. (The engine may misfire or run poorly.)

2. Poor fuel quality or water in the fuel.

3. The fuel cap may not have been properly installed and securely tightened.

These temporary malfunctions can be corrected by filling the fuel tank with good quality fuel and/or properly installing and securely tightening the gas cap. After three driving cycles without these or any other temporary malfunctions present, the Check Engine light should turn off. (A driving cycle consists of a cold engine startup followed by mixed city/highway driving.) No additional vehicle service is required.

If the Check Engine light remains on, have your vehicle serviced at the first available opportunity.

Light is blinking:

Engine misfire is occurring which could damage your catalytic converter. You should drive in a moderate fashion (avoid heavy acceleration and deceleration) and have your vehicle serviced at the first available opportunity.

Instrumentation

Under engine misfire conditions, excessive exhaust temperatures could damage the catalytic converter, the fuel system, interior

floor coverings or other vehicle components, possibly causing a fire.

Air bag readiness

Momentarily illuminates when the ignition is turned ON. If the light fails to illuminate, continues to flash or remains on, have the system serviced immediately.

Safety belt

Momentarily illuminates when the ignition is turned to the ON position to remind you to fasten your safety belts. For more information, refer to the Seating and safety restraints chapter.

Brake system warning (if equipped)

Momentarily illuminates when the ignition is turned to the ON position and the engine is off. If brake warning lamp does not illuminate at this time, seek service immediately. Also illuminates when the parking brake is engaged. Illumination after releasing the parking brake indicates low brake fluid level and the brake system should be inspected immediately.

AIR

BAG

BRAKE

Anti-lock brake system (ABS) (If equipped)

Momentarily illuminates when the ignition is turned on and the engine is off. If the light does not illuminate momentarily at start up, remains on or continues to flash, the ABS needs to be serviced. With the ABS light on, the anti-lock brake system is disabled and normal braking is still effective unless the brake warning light also remains illuminated with parking brake released.

ABS

Instrumentation

Turn signal

Illuminates when the left or right turn signal or the hazard lights are turned on. If one or both of the indicators stay on continuously or flash faster, check for a burned-out turn signal bulb. Refer to Exterior bulbs in the Maintenance and care chapter.

High beams

Illuminates when the high beam headlamps are turned on.

Charging system

Illuminates when the ignition is turned to the ON position and the engine is off. The light also illuminates when the battery is not charging properly, requiring electrical system service.

Engine oil pressure (if equipped)

Illuminates when the oil pressure falls below the normal range. Stop the vehicle as soon as safely possible and switch off the engine immediately. Check the oil level and add oil if needed. Refer to Engine oil in the Maintenance and Care chapter.

This lamp also illuminates when the ignition is turned to ON and the engine is off.

Instrumentation

Engine coolant temperature

Illuminates when the engine coolant temperature is high. Stop the vehicle as soon as safely possible, switch off the engine and let it cool.

Never remove the coolant recovery cap while the

engine is running or hot.

Refer to Engine coolant in the Maintenance and care chapter. If light stays on or continues to turn on after the vehicle warms up, have your vehicle serviced.

This light also illuminates briefly when the ignition key is turned to ON.

Air suspension (if equipped)

This light tells you if the air suspension needs repair or if the air suspension switch is OFF. For information on the air suspension system, refer to the Driving chapter.

O/D off

Illuminates when the transmission control switch has been pushed. When the light is on, the transmission does not shift into overdrive. If the light does not come on when the transmission control switch is depressed or if the light flashes when you are driving, have your vehicle serviced.

Remember to turn the ignition OFF when refueling your vehicle. Otherwise, the display will not show the addition of fuel for a few miles. At least 9.5 liters (2.5 gallons) of fuel must be added for the fuel gauge to immediately show the new fuel level.

The DTE function will flash for 5 seconds and sound a tone for 1 second when you have approximately:

• 80 km (50 miles) left before you run out of fuel

• 40 km (25 miles)

• 16 km (10 miles)

The message center will remain in the DTE function until the SELECT control is pressed to change functions.

Displayed DTE will not be equal to AVG ECON multiplied by the FUEL REMAIN value. DTE is calculated using a method that considers the fuel economy of the last 800 km (500 miles) driven.

If “CO” or “CS” is displayed, there is a problem with the fuel indication system and you should contact your dealer for service as soon as possible.

AVG ECON (average fuel economy)

Select this function to display your average fuel economy in liters/100 km or miles/gallon.

If you calculate your average fuel economy by dividing miles traveled by gallons used, your figure may be different than displayed for the following reasons:

• your vehicle was not perfectly level during fill-up

• differences in the automatic shut-off points on the fuel pumps at

service stations

• variations in top-off procedure from one fill-up to another

The air conditioning compressor will operate in all modes except VENT and FLR. However, the air conditioning will only function if the outside temperature is about 10°C (50°F) or above.

Since the air conditioner removes considerable moisture from the air during operation, it is normal if clear water drips on the ground under the air conditioner drain while the system is working and even after you have stopped the vehicle.

Controls and features

Under normal conditions, your vehicle’s climate control system should be left in any position other than MAX A/C or OFF when the vehicle is parked. This allows the vehicle to “breathe” through the outside air inlet duct.

• MAX A/C-Uses recirculated air to cool the vehicle. MAX A/C is noisier than NORM A/C but more economical and will cool the inside of the vehicle faster. Airflow will be from the instrument panel registers. This mode can also be used to prevent undesirable odors from entering the vehicle.

• NORM A/C-Uses outside air to cool the vehicle. It is quieter than MAX A/C but not as economical. Airflow will be from the instrument panel registers.

• VENT-Distributes outside air through the instrument panel registers. However, the air will not be cooled below the outside temperature because the air conditioning does not operate in this mode.

• OFF-Outside air is shut out and the fan will not operate. For short periods of time only, use this mode to prevent undesirable odors from entering the vehicle.

• FLR -Allows for maximum heating by distributing outside air through the floor ducts. However, the air will not be cooled below the outside temperature because the air conditioning does not operate in this mode.

• MIX -Distributes outside air through the windshield defroster ducts and the floor ducts. Heating and air conditioning capabilities are provided in this mode. For added customer comfort, when the temperature control knob is anywhere in between the full hot and full cold positions, the air distributed through the floor ducts will be slightly warmer than the air sent to the windshield defroster ducts. If the temperature is about 10°C (50°F) or higher, the air conditioner will automatically dehumidify the air to prevent fogging.

windshield from fogging. After a few minutes, select any desired position.

Controls and features

• To prevent humidity buildup inside the vehicle, don’t drive with the climate control system in the OFF position.

• Don’t put objects under the front seat that will interfere with the airflow to the back seats.

• Remove any snow, ice or leaves from the air intake area (at the bottom of the windshield).

• If your vehicle has been parked with the windows closed during hot weather, the air conditioner will do a much faster job of cooling if you drive for two or three minutes with the windows open. This will force most of the hot, stale air out of the vehicle. Then operate your air conditioner as you would normally.

• When placing objects on top of your instrument panel, be careful to not place them over the defroster outlets. These objects can block airflow and reduce your ability to see through your windshield. Also, avoid placing small objects on top of your instrument panel. These objects can fall down into the defroster outlets and block airflow and possibly damage your climate control system.

Automatic operation

Press AUTOMATIC and select the desired temperature. The selected temperature and the word AUTO will appear in the display window. The EATC system will either heat or cool to achieve the selected temperature. The system will automatically determine fan speed, airflow location and if fresh outside air or recirculated air is required. Fan speed remains automatic unless the fan speed thumbwheel is turned.

When in AUTOMATIC and weather conditions require heat, air will be sent to the floor. However, if the engine is not warm enough to provide heat, the fan will be at a low speed and the air will be directed to the windshield. In 3½ minutes or less, the fan speed will start to increase and the airflow location will change to the floor area.

If unusual conditions exist (i.e.-window fogging, etc.), the manual override controls allow you to select airflow locations and the fan control allows you to adjust fan speed as necessary.
