Onvehicles with no original equipment floorcovering insulation, do not carry passengersin a manner that permits prolonged skincontact with the metal floor. Failure to followthese instructions may result in fire orpersonal injury.
U.S. federal laws and certain state lawsprohibit removing or rendering inoperativeemission control system components. Similarfederal or provincial laws may apply inCanada. We do not approve of any vehiclemodification without first determiningapplicable laws.
Tampering with emissions controlsystems including related sensorsor the Diesel Exhaust Fluid systemcan result in reduced engine power and theillumination of the service engine soon light.
Tampering With a Noise ControlSystem
Federal laws prohibit the following acts:
•Removal or rendering inoperative by anyperson other than for purposes ofmaintenance.
•Repair or replacement of any device orelement of the design incorporated intoa new vehicle for the purpose of noisecontrol prior to its sale or delivery to theultimate purchaser or while it is in use.
•The use of the vehicle after any personremoves or renders inoperative anydevice or element of the design.
The U.S. Environmental Protection Agencymay presume to constitute tampering asfollows:
•Removal of hood blanket, fender apronabsorbers, fender apron barriers,underbody noise shields or acousticallyabsorptive material.
•Tampering or rendering inoperative theengine speed governor, to allow enginespeed to exceed manufacturerspecifications.
If the engine does not start, runs rough,experiences a decrease in engineperformance, experiences excess fuelconsumption or produces excessive exhaustsmoke, check for the following:

CATALYTIC CONVERTER
WARNINGS
Do not park, idle or drive your vehicleon dry grass or other dry ground cover.The emission system heats up the enginecompartment and exhaust system, creatingthe risk of fire.
The normal operating temperature ofthe exhaust system is very high. Neverwork around or attempt to repair any part ofthe exhaust system until it has cooled. Usespecial care when working around thecatalytic converter. The catalytic converterheats up to a very high temperature afteronly a short period of engine operation andstays hot after the engine is switched off.
Exhaust leaks may result in entry ofharmful and potentially lethal fumesinto the passenger compartment. If you smellexhaust fumes inside your vehicle, have yourvehicle inspected immediately. Do not driveif you smell exhaust fumes.
Your vehicle has various emission controlcomponents and a catalytic converter thatenables it to comply with applicable exhaustemission standards.
To make sure that the catalytic converter andother emission control components continueto work properly:
•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 276).
•Use only the specified fuel listed.
•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:Resulting component damage maynot be covered by the vehicle Warranty.

Engine Emission Control

HILL START ASSIST
WARNINGS
The system does not replace theparking brake. When you leave yourvehicle, always apply the parking brake.Failure to leave your vehicle securely parkedmay lead to a crash or injury. See ElectricParking Brake (page 200).
You must remain in your vehicle whenthe system turns on. At all times, youare responsible for controlling your vehicle,supervising the system and intervening, ifrequired. Failure to take care may result inthe loss of control of your vehicle, seriouspersonal injury or death.
The system will turn off if a malfunctionis apparent or if you rev the engineexcessively. Failure to take care may resultin the loss of control of your vehicle, seriouspersonal injury or death.
The system makes it easier to pull awaywhen your vehicle is on a slope without theneed to use the parking brake.
When the system is active, your vehicleremains stationary on the slope for two tothree seconds after you release the brakepedal. This allows time to move your footfrom the brake to the accelerator pedal. Thesystem releases the brakes automaticallyonce the engine has developed sufficienttorque to prevent your vehicle from rollingdown the slope. This is an advantage whenpulling away on a slope, for example from acar park ramp, traffic lights or when reversinguphill into a parking space.
Note:The system only functions when youbring your vehicle to a complete standstill inan uphill gear (for example, drive (D) whenfacing uphill or reverse (R) when facingdownhill).
Note:There is no warning light to indicatethe system is either on or off.
Using Hill Start Assist
1. Press the brake pedal to bring yourvehicle to a complete standstill. Keep thebrake pedal pressed.
2. If the sensors detect that your vehicle ison a slope, the system activatesautomatically.
3. When you remove your foot from thebrake pedal, your vehicle remains on theslope without rolling away for about twoto three seconds. This hold timeautomatically extends if you are in theprocess of driving off.
4. Drive off in the normal manner. Thesystem releases the brakes automatically.
Note:When you remove your foot from thebrake pedal and press the pedal again whenthe system is active, you will experiencesignificantly reduced brake pedal travel. Thisis normal.

PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involving brakingsystem, aftermarket roof racks,suspension, steering system, tireconstruction and wheel and tire size maychange the handling characteristics of yourvehicle and may adversely affect theperformance of the electronic stability controlsystem. In addition, installing any stereoloudspeakers may interfere with andadversely affect the electronic stabilitycontrol system. Install any aftermarket stereoloudspeaker as far as possible from the frontcenter console, the tunnel, and the frontseats in order to minimize the risk ofinterfering with the electronic stability controlsensors. Reducing the effectiveness of theelectronic stability control system could leadto an increased risk of loss of vehicle control,vehicle rollover, personal injury and death.
WARNINGS
Remember that even advancedtechnology cannot defy the laws ofphysics. It’s always possible to lose controlof a vehicle due to inappropriate driver inputfor the conditions. Aggressive driving on anyroad condition can cause you to lose controlof your vehicle increasing the risk of personalinjury or property damage. Activation of theelectronic stability control system is anindication that at least some of the tires haveexceeded their ability to grip the road; thiscould reduce the operator’s ability to controlthe vehicle potentially resulting in a loss ofvehicle control, vehicle rollover, personalinjury and death. If your electronic stabilitycontrol system activates, SLOW DOWN.
The system automatically turns on each timeyou switch the ignition on.
If a fault occurs in either the stability controlor the traction control system, you mayexperience the following conditions:
•The stability and traction control lightilluminates steadily.
•The stability control and traction controlsystems do not enhance your vehicle'sability to maintain traction of the wheels.
If a driving condition activates either thestability control or the traction control systemyou may experience the following conditions:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
•A vibration in the brake pedal.
•The brake pedal is stiffer than usual.
•If the driving condition is severe and yourfoot is not on the brake, the brake pedalmay move as the system applies higherbrake force.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:

The system may not detect objectswith surfaces that absorb reflection.Always drive with due care and attention.Failure to take care may result in a crash.
Traffic control systems, inclementweather, air brakes, external motorsand fans may affect the correct operation ofthe sensing system.This may cause reducedperformance or false alerts.
The system may not detect small ormoving objects, particularly those closeto the ground.
Note:If your vehicle is equipped withMyKey™, the sensing system cannot beturned off when a MyKey™ is present. SeePrinciple of Operation (page 65).
Note:Keep the sensors, located on thebumper or fascia, free from snow, ice andlarge accumulations of dirt. If the sensorsare covered, the system’s accuracy can beaffected. Do not clean the sensors with sharpobjects.
Note:If your vehicle sustains damage to thebumper or fascia, leaving it misaligned orbent, the sensing zone may be alteredcausing inaccurate measurement ofobstacles or false alerts.
Note:Certain add-on devices installedaround the bumper or fascia may createfalse alerts. For example, large trailerhitches, bike or surfboard racks, license platebrackets, bumper covers or any other devicethat may block the normal detection zoneof the system. Remove the add-on device toprevent false alerts.
Note:When a trailer is connected to yourvehicle, the rear parking aid may detect thetrailer and therefore provide an alert. Disablethe rear parking aid when a trailer isconnected to prevent the alert.
The sensing system warns the driver ofobstacles within a certain range of yourvehicle. The system turns on automaticallywhenever you switch the ignition on.
The system can be switched off through theinformation display menu or from the pop-upmessage that appears once you shift thetransmission into reverse (R). See GeneralInformation (page 118).
If a fault is present in the system, a warningmessage appears in the information display.See Information Messages (page 125).
REAR PARKING AID
The rear sensors are only active when thetransmission is in reverse (R). As your vehiclemoves closer to the obstacle, the rate of theaudible warning increases. When theobstacle is less than 12 in (30 cm) away, thewarning sounds continuously. If the systemdetects a stationary or receding objectfarther than 12 in (30 cm) from the corners ofthe bumper, the tone sounds for only threeseconds. Once the system detects an objectapproaching, the warning sounds again.
