Use the following procedure to prepare your vehicle for recreational towing.
WARNING!
You or others could be injured or killed if you leave the vehicle unattended with the
transfer case in the NEUTRAL (N) position without first fully engaging the parking
brake. The transfer case NEUTRAL (N) position disengages both the front and
rear drive shaft from the powertrain, and will allow the vehicle to roll, even if the
automatic transmission is in PARK (or manual transmission is in gear). The
parking brake should always be applied when the driver is not in the vehicle.
CAUTION!
It is necessary to follow these steps to be certain that the transfer case is fully in
NEUTRAL (N) before recreational towing to prevent damage to internal parts.

INSTRUMENT CLUSTER WARNING LIGHTS
-ElectronicStabilityControl(ESC)Activation/MalfunctionIndicatorLight
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 Offswitch.
-TirePressureMonitoringSystem(TPMS)Light
Each tire, including the spare (if provided), should be checked monthly when cold
and inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure
monitoring system (TPMS) that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability.
WHAT TO DO IN EMERGENCIES
105

IF THE LIGHT STARTS FLASHING INDICATING A LOW TIRE PRESSURE, ADJUST THE AIR
PRESSURE IN THE LOW TIRE TO THE AIR PRESSURE SHOWN ON THE VEHICLE PLACARD OR
TIRE INFLATION PRESSURE LABEL LOCATED ON THE DRIVER'S DOOR.
NOTE:
AFTER INFLATION, THE VEHICLE MAY NEED TO BE DRIVEN FOR 20 MINUTES
BEFORE THE FLASHING LIGHT WILL TURN OFF.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is
the driver’s responsibility to maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to 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 upon
subsequent vehicle start-ups as long as the malfunction exists. When the malfunc-
tion 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 malfunc-
tion 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. After-
market 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.
WHAT TO DO IN EMERGENCIES
106

- Engine Temperature Warning Light
This light warns of an overheated engine condition.
If the light turns on and a warning chime sounds while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the temperature reading does not return to normal,
turn the engine off immediately.
We recommend that you do not operate the vehicle or engine damage will occur. Have
the vehicle serviced immediately.
WARNING!
A hot engine cooling system is dangerous. You or others could be badly burned by
steam or boiling coolant.
- Brake Warning Light
This light monitors various brake functions, including brake fluid level and parking
brake application. If the brake light turns on it may indicate that the parking brake is
applied, that the brake fluid level is low, or that there is a problem with the anti-lock
brake system reservoir.
If the light remains on when the parking brake has been disengaged, and the fluid
level is at the full mark on the master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the Brake Booster has been
detected by the Anti-Lock Brake System (ABS)/Electronic Stability Control (ESC)
system. In this case, the light will remain on until the condition has been corrected.
If the problem is related to the brake booster, the ABS pump will run when applying
the brake and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capacity in the event of a failure to
a portion of the hydraulic system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on when the brake fluid level
in the master cylinder has dropped below a specified level. The light will remain on
until the cause is corrected.
Vehicles equipped with the Anti-Lock Brake System (ABS), are also equipped with
Electronic Brake Force Distribution (EBD). In the event of an EBD failure, the Brake
Warning Light will turn on along with the ABS Light. Immediate repair to the ABS
system is required.
Operation of the Brake Warning Light can be checked by turning the ignition switch
from the OFF position to the ON/RUN position. The light should illuminate for
approximately two seconds. The light should then turn off unless the parking brake
is applied or a brake fault is detected. If the light does not illuminate, have the light
inspected by an authorized dealer.
WHAT TO DO IN EMERGENCIES
107

The light also will turn on when the parking brake is applied with the ignition switch
in the ON/RUN position.
NOTE:
This light shows only that the parking brake is applied. It does not show the degree
of brake application.
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.
- 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 ) OFF Activation/Malfunction Warning Light
If the ESC OFF warning light comes on continuously with the engine running, a
malfunction has been detected.
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.
-ChargingSystemLight
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 while driving, stop
the vehicle and shut off the engine as soon as possible. A chime will sound when this
light turns on.
We recommend you do not operate the vehicle or engine damage will occur. Have the
vehicle serviced immediately.
