WARNING!
• Leaving the Electronic or Adaptive Speed Control system on whennot in use is dangerous. You could accidentally set the system or
cause it to go faster than you want. You could lose control and have
a collision. Always leave the Electronic or Adaptive Speed Control
system off when you are not using it.
• Electronic Speed Control can be dangerous where the system cannot maintain a constant speed. Your vehicle could go too fast for
the conditions, and you could lose control. A collision could be the
result. Do not use Electronic Speed Control in heavy traffic or on
roads that are winding, icy, snow-covered or slippery.
• Adaptive Cruise Control (ACC) is a convenience system. It is not a substitute for active driving involvement. Pay attention to road,
traffic, and weather conditions, vehicle speed, distance to the
vehicle ahead; and, brake operation to ensure safe operation of the
vehicle under all road conditions. Your attention is al ways required
while driving to maintain safe control of your vehicle. Failure to
follow these warnings can result in a collision or serious personal
injury.
The ACC system:
• Does not react to pedestrians, oncoming vehicles, and stationary objects (i.e., a stopped vehicle in a traffic jam or a disabled vehicle).
• Cannot take street, traffic, and weather conditions into account, and may be limited upon adverse sight distance conditions.
• Does not predict the lane curvature or the movement of preceding vehicles and will not compensate for such changes.
• Does not always fully recognize complex driving conditions, which
can result in wrong or missing distance warnings.
• May not detect a vehicle ahead when strong light (for example, sunrise or sunset) is directly shining on the front of the vehicle.
• Can only apply a maximum of 25% of the vehicle’s braking capability, and will not bring the vehicle to a complete stop.
You should switch off the ACC system:
• When driving in fog, heavy rain, heavy snow, sleet, heavy traffic, and complex driving situations (i.e., in highway construction zones).
• When entering a turn lane or highway off ramp; when driving on roads that are winding, icy, snow-covered, slippery, or have steep
uphill or downhill slopes; and when towing a trailer.
• When circumstances do not allow safe driving at a constant speed.
• Failure to follow these warnings can result in a collision.

Shifting Procedures
4WD HI To 4WD LOW• With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the ignition switch in the ON/RUN position or the engine running, shift the
transmission into NEUTRAL, and press the “4WD LOW” button once on
the transfer case switch. The “4WD LOW” indicator light in the
instrument cluster will begin to flash and remain on solid when the shift
is complete.
4WD LOW To 4WD HI • With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the ignition switch in the ON/RUN position or the engine running, shift the
transmission into NEUTRAL, and press the “4WD LOW” button once on
the transfer case switch. The “4WD LOW” indicator light in the
instrument cluster will flash and turn off when the shift is complete.
NOTE:
• If the shift conditions/interlocks are not met, or a transfer case motor temperature protection exists, a “For 4x4 Low Slow Below 5 MPH or 8 KPH
Put Trans in N Press 4 Low” message will flash on the Electronic Vehicle
Information Center (EVIC).
• Shifting into or out of 4WD LOW is possible with the vehicle completely stopped; however, d ifficulty may occur due to the mating clutch teeth not
being properly aligned. Several attempts may be required for clutch teeth
alignment and shift completion to occur. The preferred method is with the
vehicle rolling 0 to 3 mph (0 to 5 km/h). If the vehicle is moving faster than
3 mph (5 km/h), the transfer case will not allow the shift.
NEUTRAL Shift Procedure
• Turn the ignition switch to the ON/RUN position, engine off.
• Vehicle stopped, with foot on brake.
• Place the transmission into NEUTRAL.
• Press and hold the NEUTRAL button located near the 4WD mode control knob with a pen or similar object for four seconds. The indicator light will
begin to flash indicating the shift is in progress. The light will stop
blinking (stay on solid) when the NEUTRAL shift is complete. A “4WD
SYSTEM IN NEUTRAL” message will display on the Electronic Vehicle
Information Center (EVIC).
• Repeat these Steps to shift out of NEUTRAL.
OFF-ROAD CAPABILITIES
85

• For vehicles with Keyless Enter-N-Go™, remove the Keyless Enter-N-Go™button and use the Key Fob to complete this procedure.
• Turn the ignition switch to the ON/RUN position, but do not start the engine.
• Press and hold the brake pedal and shift the transmission into NEUTRAL.
• Using a ballpoint pen or similar object, press and hold the recessed transfer case N (Neutral) button for four seconds, until the light next to
the N symbol starts to blink, indicating shift in progress. The light will
stop blinking (stay on solid) when the shift to N (Neutral) is complete. A
“FOUR WHEEL DRIVE SYSTEM IN NEUTRAL” message will display on
the EVIC (Electronic Vehicle Information Center).
• Start the engine and shift the transmission into REVERSE.
• Release the brake pedal for five seconds and ensure that there is no vehicle movement.
• Turn the engine off and firmly apply the parking brake.
• Shift the transmission into PARK and remove the Key Fob.
• Attach the vehicle to the tow vehicle using a suitable tow bar and release the parking brake.
NOTE: Vehicles equipped with Quadra-Lift™ must be lowered to the “Park”
(lowest) level, and have automatic leveling disabled, before tying them down
(from the body) on a trailer or a flatbed truck. Refer to “Quadra-Lift™” in
“Off-Road Capabilities” for more information. If the vehicle cannot be
lowered to the “Park” level (for example, engine will not run), tie-downs must
be fastened to the axles (not the body). Failure to follow these instructions
may cause fault codes to be set and/or loss of proper tie-down tension.
CAUTION!
• Towing with the rear wheels on the ground will cause severe transmission damage. Damage from improper towing is not covered
under the New Vehicle Limited Warranty.
• Front or rear wheel lifts should not be used. Internal damage to the transmission or transfer case will occur if a front or rear wheel lift is
used when recreational towing.
• It is necessary to follow these steps to be certain that the transfer case is fully in NEUTRAL before recreational towing to prevent
damage to internal parts.
UTILITY
91

• Your vehicle has also been equipped with a TPMS malfunction indicatorto indicate when the system is not operating properly. The TPMS
malfunction indicator is combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously illuminated. This
sequence will continue each time the vehicle is restarted as long as the
malfunction exists.
• When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the installation of
replacement or alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS malfunction
telltale after replacing one or more tires or wheels on your vehicle, to
ensure that the replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
NOTE: Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C)
of air temperature change. Keep this in mind when checking tire pressure
inside a garage, especially in the Winter. Example: If garage temperature is
68°F (20°C) and the outside temperature is 32°F (0°C), then the cold tire
inflation pressure should be increased by 3 psi (21 kPa), which equals 1 psi
(7 kPa) for every 12°F (7°C) for this outside temperature condition.
CAUTION!
The TPMS has been optimized for the original equipment tires and
wheels. TPMS pressures and warning have been established for the
tire size equipped on your vehicle. Undesirable system operation or
sensor damage may result when using replacement equipment that is
not of the same size, type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or balance beads if
your vehicle is equipped with a TPMS, as damage to the sensors may
result.
BRAKE- Brake Warning Light
• The Brake Warning light illuminates when there is either a system malfunction or the parking brake is applied. If the light is on and the
parking brake is not applied, it indicates a possible brake hydraulic
malfunction, brake booster problem or an Anti-Lock Brake System
problem.
• Please have your vehicle serviced immediately.
WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the
brake system may have failed. It will take longer to stop the vehicle.
You could have a collision. Have the vehicle checked immediately.
WHAT TO DO IN EMERGENCIES
98

- Malfunction Indicator Light (MIL)
• Certain conditions, such as a loose or missing gas cap, poor fuel quality,etc., may illuminate the MIL after engine start. The vehicle should be
serviced if the light stays on through several typical driving cycles. In
most situations, the vehicle will drive normally and not require towing.
• If the MIL flashes when the engine is running, serious conditions may exist that could lead to immediate loss of power or severe catalytic
converter damage. We recommend you do not operate the vehicle. Have
the vehicle serviced immediately.
- Electronic Stability Control (ESC) Activation/MalfunctionIndicator Light
• If the “ESC Activation/Malfunction Indicator Light” comes on
continuously with the engine running, a malfunction has been detected
in the ESC system. If this light remains on after several ignition cycles,
and the vehicle has been driven several miles (kilometers) at speeds
greater than 30 mph (48 km/h), we recommend you drive to the nearest
service center and have the vehicle serviced immediately.
• The “ESC Activation/Malfunction Indicator Light” starts to flash as soon as the tires lose traction and the ESC system becomes active. If the light
begins to flash during acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your speed and driving to
the prevailing road conditions. The light also flashes when TCS is active.
To improve the vehicle's traction when starting off in deep snow, sand or
gravel, it may be desirable to switch the ESC system to Partial Off mode
by momentarily pressing the ESC Off
switch located below the
climate controls, on the switch panel.
- Charging System Light
• This light shows the status of the electrical charging system. If the charging system light remains on, it means that the vehicle is
experiencing a problem with the charging system.
• We recommend you do not continue driving if the charging system light is on. Have the vehicle serviced immediately.
- Oil Pressure Warning Light
• This light indicates low engine oil pressure. If the light turns on whiledriving, stop the vehicle and shut off the engine as soon as possible. A
chime will sound for four minutes when this light turns on.
• We recommend you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.
- Anti-Lock Brake (ABS) Light
• This light monitors the Anti-Lock Brake System (ABS).
• If the light is not on during starting, stays on, or turns on while driving,we recommend you drive to the nearest service center and have the
vehicle serviced immediately.
WHAT TO DO IN EMERGENCIES

- Electronic Throttle Control (ETC) Light
• This light informs you of a problem with the Electronic Throttle Control(ETC) system.
• If a problem is detected, the light will come on while the engine is running. Cycle the ignition key when the vehicle has completely stopped
and the shift lever is placed in the PARK position; the light should turn
off.
• If the light remains lit with the engine running, your vehicle will usually be drivable; however, see an authorized service center i mmediately. If the
light is flashing when the engine is running, immediate service is required
and you may experience reduced performance, an elevated/rough idle or
engine stall and your vehicle may require towing.
- Air Bag Warning Light
• If the light is not on during starting, stays on, or turns on while driving, have the vehicle serviced by an authorized service center immediately.
Fuel Cap/Loose Gas Cap Message
• If a “gas cap” message (shown as Check Gascap) appears, tighten thegas cap until a “clicking” sound is heard.
• If the message continues to appear for more than three days after tightening the gas cap, have the vehicle serviced by an authorized
service center immediately.
