DRIVING THROUGH WATER
WARNING
Do not drive through flowing or deepwater as you may lose control of yourvehicle.
Note:Driving through standing water cancause vehicle damage.
Note:Engine damage can occur if waterenters the air filter.
Before driving through standing water,check the depth. Never drive through waterthat is higher than the bottom of the frontrocker area of your vehicle.
When driving through standing water, drivevery slowly and do not stop your vehicle.Your brake performance and traction maybe limited. After driving through water andas soon as it is safe to do so:
•Lightly press the brake pedal to dry thebrakes and to check that they work.
•Check that the horn works.
•Check that the exterior lights work.
•Turn the steering wheel to check thatthe steering power assist works.
FLOOR MATS
WARNINGS
Always use floor mats that aredesigned to fit the foot well of yourvehicle. Only use floor mats thatleave the pedal area unobstructed. Onlyuse floor mats that are firmly secured toretention posts so that they cannot slip outof position and interfere with the pedalsor impair safe operation of your vehicle inother ways.
Pedals that cannot move freely cancause loss of vehicle control andincrease the risk of serious personalinjury.
Always make sure that the floormats are properly attached to theretention posts in the carpet that aresupplied with your vehicle. Floor mats mustbe properly secured to both retention poststo make sure mats do not shift out ofposition.
Never place floor mats or any othercovering in the vehicle foot well thatcannot be properly secured toprevent them from moving and interferingwith the pedals or the ability to control thevehicle.
Never place floor mats or any othercovering on top of already installedfloor mats. Floor mats should alwaysrest on top of vehicle carpeting surface andnot another floor mat or other covering.Additional floor mats or any other coveringwill reduce the pedal clearance andpotentially interfere with pedal operation.

If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a longor steep grade in high ambienttemperatures.
At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
You may notice a reduction in vehiclespeed caused by reduced engine power inorder to manage the engine coolanttemperature. Your vehicle may enter thismode if certain high-temperature andhigh-load conditions take place. Theamount of speed reduction depends onvehicle loading, grade and ambienttemperature. If this occurs, there is no needto pull off the road. You can continue todrive your vehicle.
The air conditioning may automaticallyturn on and off during severe operatingconditions to protect the engine fromoverheating. When the coolanttemperature decreases to the normaloperating temperature, the air conditioningturns on.
If the coolant temperature gauge movesfully into the red zone, or if the coolanttemperature warning or service enginesoon messages appear in your informationdisplay, do the following:
1. Pull off the road as soon as safelypossible and shift the transmission intopark (P).
2. Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. Afterseveral minutes, if the temperaturedoes not drop, follow the remainingsteps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4. If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5. If the coolant level is normal, restartthe engine and continue.
