• Park Mode (Lowers the vehicle approximately 1.5 in (38 mm) –This position lowers the vehicle for easier passenger entry and
exit. Press the “Down” button once from NRH while the vehicle
speed is below 25 mph (40 km/h). Once the vehicle speed
goes below 15 mph (24 km/h) the vehicle height will begin to
lower. The Indicator lamp on the “Down” button will be
illuminated when the vehicle is in Park Mode.
WARNING!
• You or others could be injured if you leave the vehicle unattendedwith the transfer case in the N (Neutral) position without first fully
engaging the parking brake. The transfer case N (Neutral) position
disengages both the front and rear driveshafts from the powertrain
and will allow the vehicle to move regardless of the transmission
position. The parking brake should always be applied when the
driver is not in the vehicle.
• The air suspension system uses a high pressure volume of air to operate the system. To avoid personal injury or damage to the
system, see your authorized dealer for service.
Hill Start Assist/Hill Descent Control
• The Hill Start Assist system assists the driver when starting a vehiclefrom a stop on a hill.
• The Hill Descent Control system maintains vehicle speed while descending hills during off-road driving situations and is available in
4WD HIGH range and 4WD LOW range.
• Refer to your Owner's Manual on the DVD for further details.

• 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.

- 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.
Oil Change IndicatorMessage
• If an “oil change” message (shown as Oil Change Required) appears and a single chime sounds, it is time for your next required oil change.
Resetting The Light After Servicing
Vehicles Equipped With Keyless Enter-N-Go™ • Without pressing the brake pedal, push the ENGINE START/STOP button and cycle the ignition to the ON/RUN position (Do not start the engine.)
• Fully depress the accelerator pedal, slowly, three times within 10 seconds.
• Without pressing the brake pedal, push the ENGINE START/STOP button once to return the ignition to the OFF/LOCK position.
Vehicles Not Equipped With Keyless Enter-N-Go™
• Turn the ignition switch to the ON/RUN position (Do not start the engine.)
• Fully depress the accelerator pedal, slowly, three times within 10 seconds.
