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.

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 461).

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.

ELECTRIC POWER STEERING
HOW DOES ELECTRIC POWERSTEERING WORK
The electric power steering system assiststhe brake system to help operateadvanced stability control and accidentavoidance systems.
If your vehicle loses electrical power ordetects a concern when you are driving thesystem switches off and you retain normalsteering function. Additionally, wheneverthe battery is disconnected or a newbattery is installed, you must drive yourvehicle a short distance before the systemrelearns the strategy and reactivates allsystems.
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.

Muddy waters can reduce the coolingsystem effectiveness by depositing debrisinto the radiator.
Extra care must be taken crossing any typeof water. Do not drive into water unlessnecessary. You should only drive throughareas that are designated and approved.
High currents even in shallow water canwash the dirt out from around your tires orpush your vehicle across slippery rocks orsurfaces.
Never attempt to cross flowing water thatis deeper than your vehicles groundclearance. Even in low currents yourvehicles body surface area can be pusheddownstream and out of control.
Do not cross any body of water that is fastflowing and rising, wait for the flow rate toreduce.
Determine exit points that are downstreamof your entry point to allow for drifting.
If there are other vehicles ahead, wait untilthey’ve left the water. Unsettled water canmake a safe passage more challenging.
Know your vehicle’s abilities and be ableto recover it if something goes wrong.
Keep the doors fully closed during a watercrossing.
Vehicles used to traverse water regularlyshould be periodically inspected for signsof water ingestion in all of the vehicle'sfluids. If water is found inside your vehiclefluids, service your vehicle or see anauthorized dealer.
After driving through water and as soon asit is safe to do so, check the brakes, horn,lights, and steering wheel to make sureeverything is still in working order.
Avoid Getting High-Centered
Always keep available ground clearancein mind and pick a route that minimizes therisk of catching the underside of the vehicleon an obstacle and getting high-centered.
Freeing A Stuck Vehicle
WARNING: Do not spin the wheelsat over 34 mph (55 km/h). The tires mayfail and injure a passenger or bystander.
Recovery hooks are mounted to thevehicle's structure and are used to pull outthe vehicle from a surface or location whenstuck. Recover your vehicle using varioustowing apparatus attached to yourrecovery hook such as winch, open hook,or strap.
Note:Do not use recovery hooks torecreationally tow your vehicle. SeeRecreationally Towing Your Vehicle (page338).
If your vehicle gets stuck in mud or snow,you may rock it out by shifting betweenforward and reverse gears, stoppingbetween shifts in a steady pattern. Pressthe accelerator in each gear.
Note: Do not rock your vehicle if the engineis not at normal operating temperaturedamage to the transmission may occur.
Note:Do not rock your vehicle for morethan a minute damage to the transmissionand tires may occur or the engine mayoverheat.
If you are unable to free your vehicle callroadside assistance. See RoadsideAssistance (page 328).
