Note:The engine block heater is mosteffective when outdoor temperatures arebelow 0°F (-18°C). We recommend the useof engine block heater to improve enginecold start performance.
USING THE ENGINE BLOCK HEATER
Make sure the receptacle terminals are cleanand dry prior to use. Clean them with a drycloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hours ofenergy per hour of use. The system does nothave a thermostat. It achieves maximumtemperature after approximately three hoursof operation. Using the engine block heaterlonger than three hours does not improvesystem performance and unnecessarily useselectricity.

If it flashes, engine misfire could beoccurring. Increased exhaust gastemperatures could damage the catalyticconverter or other vehicle components.Avoid heavy acceleration and deceleration,and have your vehicle checked as soon aspossible.
Powertrain Warning Lamp
If it illuminates when the engine isrunning, this indicates a powertrainor four-wheel drive fault. If itflashes when you are driving, immediatelyreduce the vehicle speed. Avoid heavyacceleration and deceleration, and have yourvehicle checked as soon as possible.
If both lamps illuminate when the engine isrunning, stop your vehicle as soon as it issafe to do so. Continuing to drive yourvehicle could cause reduced power or theengine to stop. Switch the ignition off andattempt to restart the engine. Have yourvehicle checked as soon as possible.

WHAT IS THE CATALYTIC
CONVERTER
The catalytic converter is part of yourvehicle's emissions system and filters harmfulpollutants from the exhaust gas.
CATALYTIC CONVERTER
PRECAUTIONS
WARNING: Do not park, idle or driveyour vehicle on dry grass or other dryground cover. The emission system heatsup the engine compartment and exhaustsystem, creating the risk of fire.
WARNING: The normal operatingtemperature of the exhaust system is veryhigh. Never work around or attempt torepair any part of the exhaust system untilit has cooled. Use special care whenworking around the catalytic converter.The catalytic converter heats up to a veryhigh temperature after only a short periodof engine operation and stays hot after theengine is switched off.
WARNING: Exhaust leaks may resultin entry of harmful and potentially lethalfumes into the passenger compartment. Ifyou smell exhaust fumes inside yourvehicle, have your vehicle inspectedimmediately. Do not drive if you smellexhaust fumes.
To avoid damaging the catalytic converter:
•Do not crank the engine for more than10 seconds at a time.
•Do not run the engine with a spark pluglead disconnected.
•Do not push-start or tow-start yourvehicle. Use booster cables. See JumpStarting Precautions (page 318).
•Use the correct fuel. See Fuel andRefueling (page 203).
•Do not switch the ignition off when yourvehicle is moving.
•Avoid running out of fuel.
•Have the items listed in scheduledmaintenance information performedaccording to the specified schedule.
Note:Do not make any unauthorizedchanges to your vehicle or engine. By law,vehicle owners and anyone whomanufactures, repairs, or services a fleet ofvehicles are not permitted to intentionallyremove an emission control device orprevent it from working.

BRAKES – TROUBLESHOOTING
BRAKES – WARNING LAMPS
WARNING: Driving your vehicle withthe warning lamp on is dangerous. Asignificant decrease in brakingperformance may occur. It may take youlonger to stop your vehicle. Have yourvehicle checked as soon as possible.Driving extended distances with theparking brake engaged can cause brakefailure and the risk of personal injury.
If the ABS indicator illuminateswhen you are driving, this indicatesa malfunction. Your vehiclecontinues to have normal braking withoutthe anti-lock braking system function. Seean authorized dealer.
It also momentarily illuminates when youswitch the ignition on to confirm the lamp isfunctional. If it does not illuminate when youswitch the ignition on, or begins to flash atany time, have the system checked by anauthorized dealer.
The brake indicator momentarilyilluminates when you switch theignition on to confirm the lamp isfunctional. It may also illuminate when youapply the parking brake and the ignition ison.
