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 a crash when:
•You drive too close to the vehicle infront of you.
•Your vehicle is hydroplaning.
•You take corners too fast.
•The road surface is poor.
BRAKE OVER ACCELERATOR
If your accelerator pedal becomes stuckor trapped:
•Apply steady and firm pressure to thebrake pedal to slow the vehicle andreduce power.
•Bring your vehicle to a complete stopand place it in park (P).
•Switch the power off.
•Apply the parking brake.
Inspect the accelerator pedal for anyinterference. If none are found and thecondition persists, have your vehiclechecked as soon as possible. If yourvehicle has to be towed, we recommendthat you contact a professional towingservice.
LOCATING THE BRAKE FLUID
RESERVOIR
See Under Hood Overview (page 325).
CHECKING THE BRAKE FLUID
WARNING: Do not use any fluidother than the recommended brake fluidas this will reduce brake efficiency. Useof incorrect fluid could result in the lossof vehicle control, serious personal injuryor death.
WARNING: Only use brake fluidfrom a sealed container. Contaminationwith dirt, water, petroleum products orother materials may result in brakesystem damage or failure. Failure toadhere to this warning could result in theloss of vehicle control, serious personalinjury or death.
WARNING: Do not allow the fluidto touch your skin or eyes. If thishappens, rinse the affected areasimmediately with plenty of water andcontact your physician.
WARNING: The brake systemcould be affected if the brake fluid levelis below the MIN mark or above the MAXmark on the brake fluid reservoir.

1.Park your vehicle on a level surface.
2.Look at the brake fluid reservoir to seewhere the brake fluid level is relativeto the MIN and the MAX marks on thereservoir.
Note:To avoid fluid contamination, thereservoir cap must remain in place and fullytight, unless you are adding fluid.
Only use fluid that meets ourspecifications. See Capacities andSpecifications (page 366).

TROUBLESHOOTING
BRAKES – WARNING LAMPS
WARNING: Driving your vehiclewith the warning lamp on is dangerous.A significant 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, thisindicates a malfunction. Yourvehicle continues to have normal brakingwithout the anti-lock braking systemfunction. See an authorized dealer.
It also momentarily illuminates when youswitch the ignition on to confirm the lampis functional. If it does not illuminate whenyou switch the ignition on, or begins toflash at any time, have the system checkedby an authorized dealer.
The brake indicator momentarilyilluminates when you switch theignition on to confirm the lampis functional. It may also illuminate whenyou apply the parking brake and theignition is on. If it illuminates when yourvehicle is moving, make sure the parkingbrake is disengaged. If the parking brakeis disengaged, this indicates low brake fluidlevel or a brake system fault. See anauthorized dealer.

ELECTRIC POWER STEERING
ELECTRIC POWER STEERINGPRECAUTIONS
WARNING: The electric powersteering system has diagnostic checksthat continuously monitor the system. Ifa fault is detected, a message displaysin the information display. Stop yourvehicle as soon as it is safe to do so.Switch the vehicle off. After at least 10seconds, switch the vehicle on andwatch the information display for asteering system warning message. If asteering system warning messagereturns, have the system checked assoon as possible.
WARNING: If the system detectsan error, you may not feel a difference inthe steering, however a serious conditionmay exist. Have your vehicle checked assoon as possible. Failure to do so mayresult in loss of steering control.
Adapt your speed and driving behavioraccording to reduced steering assist.
Extreme continuous steering may increasethe effort to steer. This occurs to preventinternal overheating and damage to thesteering system. If this occurs, you will notlose the ability to steer your vehiclemanually nor will it cause damage to thesystem. Normal steering and driving allowsthe system to cool down and steeringassist returns to normal.
Note:There is no fluid reservoir to check orfill.
ELECTRIC POWER STEERINGADAPTIVE STEERING
Adaptive Learning (If Equipped)
Adaptive learning helps correct roadirregularities and improves overall handlingand steering. It communicates with thebrake system to help operate advancedstability control and crash avoidancesystems.
Note:When the battery is disconnected ora new battery is installed, you must driveyour vehicle a short distance before thesystem relearns the strategy and reactivatesall systems.
Steering Tips
If the steering wanders or pulls, check for:
•An improperly inflated tire.
•Uneven tire wear.
•Loose or worn suspensioncomponents.
•Improper vehicle alignment.
Note:A high crown in the road or highcrosswinds could also make the steeringwander or pull.

Note:Some of these components areunderneath the luggage compartment coverand cannot be seen unless the cover isremoved. See Installing and Removingthe Luggage Compartment Cover (page297).
CHECKING THE COOLANT
WARNING: Do not remove thecoolant reservoir cap when the vehicleis on or the cooling system is hot. Wait10 minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
WARNING: Do not put coolant inthe windshield washer reservoir. Ifsprayed on the windshield, coolant couldmake it difficult to see through thewindshield.
WARNING: Do not add coolantfurther than the MAX mark.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Your vehicle has a battery cooling systemand a motor electrical cooling system. SeeUnder Hood Overview (page 325). Theluggage compartment covers need to beremoved in order to access the reservoirs.See Installing and Removing theLuggage Compartment Cover (page 297).
When the electric motor is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 410).
Maintain coolant concentration within48% to 50%, which equates to a freezepoint between -29–-35°F (-34–-37°C).Check coolant concentration using arefractometer. We do not recommend theuse of hydrometers or coolant test stripsfor measuring coolant concentration.
Adding Coolant
It is very important to use predilutedcoolant approved to the correctspecification in order to avoid plugging thesmall passageways in the electric motorcooling system. See Cooling SystemCapacity and Specification (page 366).
Do not mix different colors or types ofcoolant in your vehicle. Mixing of coolantsor using an incorrect coolant may harm theelectric motor or cooling systemcomponents and may cause damage thatthe vehicle warranty may not cover.
Note:Automotive fluids are notinterchangeable.
Note:Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the electricmotor cooling or heating systems.
