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 engineis running, this indicates apowertrain or four-wheel drivefault. If it flashes when you are driving,immediately reduce the vehicle speed.Avoid heavy acceleration and deceleration,and have your vehicle checked as soon aspossible.
If both lamps illuminate when the engineis running, stop your vehicle as soon as itis safe 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 filtersharmful pollutants from the exhaust gas.
CATALYTIC CONVERTER
PRECAUTIONS
WARNING: Do not park, idle ordrive your vehicle on dry grass or otherdry ground cover. The emission systemheats up the engine compartment andexhaust system, creating the risk of fire.
WARNING: The normal operatingtemperature of the exhaust system isvery high. Never work around or attemptto repair any part of the exhaust systemuntil it has cooled. Use special care whenworking around the catalytic converter.The catalytic converter heats up to a veryhigh temperature after only a shortperiod of engine operation and stays hotafter the engine is switched off.
WARNING: Exhaust leaks mayresult in entry of harmful and potentiallylethal fumes into the passengercompartment. If you smell exhaustfumes inside your vehicle, have yourvehicle inspected immediately. Do notdrive if you smell exhaust 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 the Vehicle (page 330).
•Use the correct fuel. See Fuel andRefueling (page 179).
•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.

BRAKE SHIFT INTERLOCK
WHAT IS BRAKE SHIFTINTERLOCK
Brake shift interlock allows you to shiftyour vehicle out of park (P) in the event ofan electrical malfunction or emergency.
BRAKE SHIFT INTERLOCKPRECAUTIONS
WARNING: Do not drive yourvehicle until you verify that thestoplamps are working.
WARNING: When doing thisprocedure, you need to take thetransmission out of park (P) whichmeans your vehicle can roll freely. Toavoid unwanted vehicle movement,apply the parking brake prior to doingthis procedure. Use wheel chocks ifappropriate.
WARNING: If the parking brake isfully released, but the brake warninglamp remains illuminated, the brakesmay not be working properly. Have yourvehicle checked as soon as possible.

BRAKE PRECAUTIONS
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when leaving a car wash ordriving from standing water to dry thebrakes.
Note:Depending on applicable laws andregulations in the country where your vehiclewas originally built, the stoplamps couldflash during heavy braking. The hazardwarning flashers could also turn on whenyour vehicle comes to a stop.
ANTI-LOCK BRAKING SYSTEM
ANTI-LOCK BRAKING SYSTEMLIMITATIONS
The anti-lock braking system does noteliminate the risk of crash when:
•You drive too closely to the vehicle infront of you.
•Your vehicle is hydroplaning.
•You take corners too fast.
•The road surface is poor.
Note: If the system activates, the brakepedal could pulse and travel further.Maintain pressure on the brake pedal.
BRAKE OVER ACCELERATOR
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Move the transmission to park (P),switch the engine off and apply the parkingbrake. Inspect the accelerator pedal forany interference. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.

WHAT IS TRACTION CONTROL
The traction control system helps to avoiddrive wheel spin and loss of traction.
HOW DOES TRACTION
CONTROL WORK
If your wheels begin to spin, the loss oftraction can compromise steering controland stability of the vehicle. The tractioncontrol system applies the brakes toindividual wheels and when needed,reduces engine power at the same time toincrease traction.
SWITCHING TRACTION
CONTROL ON AND OFF
WARNING: Operating your vehiclewith the traction control disabled couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
The system turns on each time you switchthe ignition on.
If your vehicle is stuck in mud or snow,switching traction control off may bebeneficial as this allows the wheels to spin.
Switching the System Off
The switch for the stability andtraction control system is on theinstrument panel.
When you switch the system off, amessage and an illuminated icon appearon the instrument cluster.
Use the switch again to return the tractioncontrol system to normal operation.
Note:When you switch traction control off,stability control remains fully active.
Note:When you place your vehicle intofour-wheel drive low (4L), the tractioncontrol disables. Traction control resumeswhen you put your vehicle back intotwo-wheel drive or four-wheel drive high(4H).
Note:For additional information on thetraction and stability control systems. SeeStability Control (page 219).
