SAFETY FEATURES
Four-Wheel Anti-Lock Brake System (ABS)
The Four-Wheel Anti-Lock Brake System (ABS) is designed
to aid the driver in maintaining vehicle control under
adverse braking conditions. The system operates with a
separate computer to modulate hydraulic pressure, to
prevent wheel lock-up and to help avoid skidding on
slippery surfaces.
The system's pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
The ABS includes an amber ABS Warning Light. When the
light is illuminated, the ABS is not functioning. The system
reverts to standard non-anti-lock brakes. Turning the igni-
tion OFF and ON again may reset the ABS if the fault
detected was only momentary.
WARNING!
• The ABS contains sophisticated electronic equipment that may be susceptible to interference caused by
improperly installed or high output radio transmitting
equipment. This interference can cause possible loss of
anti-lock braking capability. Installation of such equip -
ment should be performed by qualified professionals.
• Pumping of the Anti-Lock Brakes will diminish their effectiveness and may lead to a collision. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.
• The ABS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking
or steering efficiency beyond that afforded by the
condition of the vehicle brakes and tires or the traction
afforded.

100 SAFETY
ESC Activation/Malfunction Indicator Light And ESC
OFF Indicator Light The ESC Activation/Malfunction Indicator Light in
the instrument cluster will come on when the igni -
tion switch is turned to the MAR (ON/RUN) posi -
tion for four seconds. 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 (km) at speeds greater
than 30 mph (48 km/h), see an authorized dealer as soon as
possible to have the problem diagnosed and corrected.
The ESC Activation/Malfunction Indicator Light (located in
the instrument cluster) starts to flash as soon as the tires lose
traction and the ESC system becomes active. The ESC Activa
-
tion/Malfunction Indicator Light also flashes when TCS is
active. If the ESC Activation/Malfunction Indicator 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.
NOTE:
• The ESC Activation/Malfunction Indicator Light and the ESC OFF Indicator Light come on momentarily each time
the ignition switch is turned ON.
• Each time the ignition is turned ON, the ESC system will be ON even if it was turned off previously.
The ESC OFF Indicator Light indicates the Electronic
Stability Control (ESC) is partially off.
• Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteristics
of your vehicle, and may negatively affect the perfor -
mance of the ESC system. Changes to the steering
system, suspension, braking system, tire type and size
or wheel size may adversely affect ESC performance.
Improperly inflated and unevenly worn tires may also
degrade ESC performance. Any vehicle modification or
poor vehicle maintenance that reduces the effective -
ness of the ESC system can increase the risk of loss of
vehicle control, vehicle rollover, personal injury and
death.

SAFETY 105
Base SystemThis is the TPMS warning indicator located in the
instrument cluster.
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure levels.
Sensors, mounted to each wheel as part of the valve stem,
transmit tire pressure readings to the Receiver Module.
NOTE:
It is particularly important for you to check the tire pressure
in all of the tires on your vehicle regularly and to maintain
the proper pressure.
The TPMS consists of the following components:
• Receiver Module
• Four Tire Pressure Monitoring sensors
• Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring System Warning Light will
illuminate in the instrument cluster, an audible chime will be
activated, and the “Check tire pressure” text message will
display when one or more of the four active road tire pres -
sures are low. Should this occur, you should stop as soon as possible, check the inflation pressure of each tire on your
vehicle, and inflate each tire to the vehicle’s recommended
cold placard pressure value. The system will automatically
update and the Tire Pressure Monitoring Light will extin
-
guish once the updated tire pressures have been received.
The vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) to receive this information.
Check TPMS Warnings
The Tire Pressure Monitoring Warning Light will flash on
and off for 75 seconds and remain on solid when a system
fault is detected, an audible chime will be activated and a
proper text message will be displayed. If the ignition key is
cycled, this sequence will repeat providing the system fault
still exists. The Tire Pressure Monitoring Warning Light will
turn off when the fault condition no longer exists. A system
fault can occur with any of the following scenarios:
1. Jamming due to electronic devices or driving next to facil -
ities emitting the same radio frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.

190 STARTING AND OPERATING
(Continued)
WARNING!
• Make certain that the load is secured in the trailer and will not shift during travel. When trailering cargo that
is not fully secured, dynamic load shifts can occur that
may be difficult for the driver to control. You could lose
control of your vehicle and have a collision.
• When hauling cargo or towing a trailer, do not overload your vehicle or trailer. Overloading can cause a loss of
control, poor performance or damage to brakes, axle,
engine, transmission, steering, suspension, chassis
structure or tires.
• Safety chains must always be used between your vehicle and trailer. Always connect the chains to the
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.
• Vehicles with trailers should not be parked on a grade.When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle transmission in PARK. For
four-wheel drive vehicles, make sure the transfer case
is not in NEUTRAL. Always, block or "chock" the
trailer wheels.
• GCWR must not be exceeded.
• Total weight must be distributed between the tow vehicle and the trailer such that the following four
ratings are not exceeded:
• GVWR
• GTW
• GAWR
• Tongue weight rating for the trailer hitch utilized.
