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.
LOCATING THE BRAKE FLUID
RESERVOIR

WARNING: Do not use dieselengine exhaust braking when the roadsurface is slippery. Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle.
USING THE DIESEL ENGINE
EXHAUST BRAKE
This feature increases engine braking athigher engine speeds to provide bettergrade descent control with less brake andtransmission wear and tear.
Note:Use this when driving downhill andcarrying heavy loads or trailering.
Benefits of engine braking are:
•Lower brake temperature.
•Reduced brake fade.
•Longer brake life.
•Improved driving and trailering control.
Press the button on the switchbank next to the audio unit toswitch the system on or off.
There are two engine brake modes, manualand automatic.
The following conditions must be met touse exhaust brake:
•Your vehicle is in a forward gear.
•The engine speed is above 1300 RPM.
•Your foot is off the accelerator.
You can use this feature with tow/haul orprogressive range selection to providefurther increased engine braking. Thetransmission upshifts to prevent the enginefrom entering the red zone on thetachometer.
Manual Engine Braking
1.Press the button to switch on manualengine braking.
2.Release the accelerator pedal tomaximize engine braking.
3.Apply the brakes. The transmissiondownshifts to lower gears.
Note:The engine braking feature onlyfunctions when you release the accelerator.
Note:You can shift the transmission tolower gears with progressive range selectionor manual shifting independent of pressingthe brakes.
Note:You can also use manual enginebraking with cruise control to improve gradedescent control.
Note:If your vehicle has adaptive cruisecontrol, the speed control system uses theselected engine brake mode, transmissiongears, and brakes to maintain the set speedand distance to the vehicle being followed.

WHAT IS REVERSE BRAKE
ASSIST
Reverse brake assist is designed to reduceimpact damage or assist in avoiding acollision while in reverse (R). Using sensorson the rear of the vehicle, it can detect apossible collision and apply the brakes. Iffull braking occurs, the system attemptsto stop the vehicle a safe distance fromthe obstacle.
HOW DOES REVERSE BRAKE
ASSIST WORK
Reverse brake assist functions when inreverse (R) and traveling at a speed of1–7 mph (2–12 km/h).
If the system detects an obstacle behindyour vehicle, it provides a warning throughthe rear parking aid or cross traffic alertsystem.
