Operating Four-Wheel Drive witha Spare or Worn Tires
Your four-wheel drive system is notintended to provide full function with tiresthat have different levels of wear or witha dissimilar spare tire. Incorrect use offour-wheel drive with such tires can causesystem damage.
If there is a difference in the level of wearamong tires on the vehicle or if you installa dissimilar spare tire on the vehicle, do notuse 4WD High or 4WD Low (if equipped)other than to get your vehicle unstuck.After getting your vehicle unstuck, shift to2H by performing the following steps:
1.Come to a stop on a flat, horizontalsurface
2.Shift the transmission to park (P) forautomatic transmissions and neutral(N) for manual transmissions.
3.Switch to two-wheel drive mode.
4.Shift the transmission to reverse (R).
5.Shift the transmission to drive (D) forautomatic transmissions and to firstgear for manual transmissions. Thisensures the transfer case system is nottrapped in place.
Mechanical Shift Blocking
On four-wheel drive vehicles with amechanically locked four-wheel drive highmode, the transfer case distributes torqueto the front wheels by mechanicallyinterlocking the front and rear driveshaftstogether. Various external factors affectshifting performance of this type of systemincluding, but not limited to:
•Vehicle acceleration.
•Dissimilar tire sizes.
•Steering input.
If the system detects a mechanical shiftblockage at speed after you selecttwo-wheel drive high, the message "4x4Unable to Disengage See Manual", coulddisplay momentarily. If this messagedisplays, one or more of the followingactions can relieve the mechanical shiftblock:
•Momentary acceleration.
•Momentary braking.
•Bringing the vehicle to a stop.
•Shifting the transmission to neutral andback to drive.
•Shifting the transmission to reverseand back to drive.
•Driving the vehicle around a tight turnat a slow speed.
SWITCHING FOUR-WHEEL
DRIVE ON AND OFF
A vehicle that comes with four-wheel drive,when selected, has the ability to use allfour wheels to power itself. This increasestraction, which may enable you to safelydrive over terrain and road conditions thata conventional two-wheel drive vehiclecannot.
On some four-wheel drive models, theinitial shift from two-wheel drive tofour-wheel drive while the vehicle ismoving can cause a momentary clunk andratcheting sound. These sounds are normalas the front drivetrain comes up to speedand are not cause for concern.

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.

We recommend the use of a wheel lift anddollies or flatbed equipment to tow yourvehicle. Vehicle damage could occur iftowed incorrectly, or by any other means.
Front-wheel and rear-wheel drive vehiclesmust have their designated drive wheelsoff the ground regardless of towingdirection. Use tow dollies to preventdamage to the transmission.
All-wheel or four-wheel drive vehiclesrequire that all wheels be off the groundusing a wheel lift and dollies or flatbedequipment. This prevents damage to thetransmission and drive system.
Note:You need to switch on the ignition tounlock the steering.
Note:Make sure you check the steeringcolumn before towing. It could lock if thebattery is dead.
FAIL-SAFE COOLING
WHAT IS FAIL-SAFE COOLING
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs due tooverheating.
The fail-safe distance depends on outsidetemperature, vehicle load and terrain.
HOW DOES FAIL-SAFE COOLINGWORK
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs, your vehicle stilloperates, however:
•Engine power is limited.
•The air conditioning system turns off.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan re-start the engine.
Note:Have your vehicle checked as soonas possible to minimize engine damage.
DRIVING WHEN FAIL-SAFE MODEIS ACTIVATED
WARNING: Fail-safe mode is foruse during emergencies only. Operateyour vehicle in fail-safe mode only aslong as necessary to bring your vehicleto rest in a safe location and seekimmediate repairs. When in fail-safemode, your vehicle will have limitedpower, will not be able to maintainhigh-speed operation, and maycompletely shut down without warning,potentially losing engine power, powersteering assist, and power brake assist,which may increase the possibility of acrash resulting in serious injury.
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes 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.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
