WARNING!
Speed Control can be dangerous where the system
can’t maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose
control. An accident could be the result. Don’t use
Speed Control in heavy traffic or on roads that are
winding, icy, snow-covered, or slippery.
To Accelerate For Passing
Depress the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Speed Control On Hills
NOTE:The speed control system maintains speed up
and down hills. A slight speed change on moderate hills
is normal.
On steep hills a greater speed loss or gain may occur so
it may be preferable to drive without speed control.
ANTI-LOCK BRAKE SYSTEM (ABS) — IF
EQUIPPED
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lockup and
help avoid skidding on slippery surfaces during braking.

Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system functions similar to
a limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESP are in
either the “Partial Off” or “Full Off” modes. Refer to
“Electronic Stability Program (ESP)” in this Section of this
manual.
Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver ’s steering wheel input and the
speed of the vehicle. When ERM determines that the rate
of change of the steering wheel angle and vehicles speed
are sufficient to potentially cause wheel lift, it applies the
brake of the appropriate wheel and may also reduce
engine power to lessen the chance that wheel lift will
occur. ERM will only intervene during very severe or
evasive driving maneuvers.
ERM can only reduce the chance of wheel lift occurring
during severe or evasive driving maneuvers. It can not
prevent wheel lift due to other factors such as road
conditions, leaving the roadway or striking objects or
other vehicles.

30. Electronic Stability Program (ESP) Indicator Light
The malfunction light for the ESP is combined
with BAS. The yellow “ESP/BAS Warning
Light” comes on when the ignition switch is
turned to the ON position. They should go out
with the engine running. If the “ESP/BAS Warning
Light” comes on continuously with the engine running, a
malfunction has been detected in either the ESP or the
BAS 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), see
your authorized dealer as soon as possible.
31. 4WD! Warning Light
This light monitors the 4-Wheel Drive (4WD)
system. The light will come on, for a bulb
check, when the ignition key is turned to the
ON position and may stay on for as long as
three seconds.When lit solid:There is an 4WD system fault. 4WD
performance will be at a reduced level. Service the 4WD
system soon.
When blinking:The 4WD system is temporarily dis-
abled due to overload condition.
32. Electronic Vehicle Information Center Display — If
Equipped
When the appropriate conditions exist, this display
shows the Electronic Vehicle Information Center (EVIC)
messages.
33. Electronic Vehicle Information Center (EVIC)
Button — If Equipped
Pushing this button, will change the display to the
choices available for EVIC.

TWO TYPES OF SIGNALS
There are two basic types of radio signals: AM or
Amplitude Modulation, in which the transmitted sound
causes the amplitude, or height, of the radio waves to
vary; and FM or Frequency Modulation, in which the
frequency of the wave is varied to carry the sound.
AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.
NOTE:The radio, steering wheel radio controls (if
equipped), and six-disc CD/DVD changer (if equipped)will remain active for up to 10 minutes after the ignition
switch has been turned OFF. Opening a vehicle front
door will cancel this feature.
ELECTRONIC DIGITAL CLOCK
The clock and radio each use the display panel built into
the radio. A digital readout shows the frequency and/or
time in hours and minutes (depending on your radio
model), whenever the ignition switch is in the ON or
ACC position.
When the ignition switch is in the OFF position, or when
the radio frequency is being displayed, timekeeping is
accurately maintained.
On the AM/FM/CD (6-disc) radio, the time button
alternates the location of the time and frequency on the
display. On the AM/FM/CD (single-disc) radio, only one
of the two, time or frequency, is displayed.

The Basics of Off-Road Driving
You will encounter many types of terrain driving off-
road. You should be familiar with the terrain and area
before proceeding. There are many types of surface
conditions: hard packed dirt, gravel, rocks, grass, sand,
mud, snow and ice. Every surface has a different effect on
your vehicle’s steering, handling and traction. Control-
ling your vehicle is one of the keys to successful off-road
driving, so always keep a firm grip on the steering wheel
and maintain a good driving posture. Avoid sudden
accelerations, turns or braking. In most cases there are no
road signs, posted speed limits or signal lights. Therefore
you will need to use your own good judgment on what is
safe and what isn’t. When on a trail you should always be
looking ahead for surface obstacles and changes in
terrain. The key is to plan your future driving route while
remembering what you are currently driving over.CAUTION!
Never park your vehicle over dry grass or other
combustible materials. The heat from your vehicle
exhaust system could cause a fire.
WARNING!
Always wear your seat belt and firmly tie down
cargo. Unsecured cargo can become projectiles in an
off-road situation.

feel confident with the vehicle and your abilities. You
should always climb hills straight up and down. Never
attempt to climb a hill on an angle.
•Before Climbing A Steep Hill– As you approach a
hill consider its grade or steepness. Determine if it is
too steep. Look to see what the traction is on the hill
side trail. Is the trail straight up and down? What is on
top and the other side? Are there ruts, rocks, branches
or other obstacles on the path? Can you safely recover
the vehicle if something goes wrong? If everything
looks good and you feel confident, then you should
use low (L Off-Road) with the 4WD LOCK engaged
and proceed with caution maintaining your momen-
tum as you climb the hill
•Driving Up Hill– Once you have determined your
ability to proceed and have shifted into the appropri-
ate gear, line your vehicle up for the straightest
possible run. Accelerate with an easy constant throttleand apply more power as you start up the hill. Do not
race forward into a steep grade, the abrupt change of
grade could cause you to lose control. If the front end
begins to bounce, ease off the throttle slightly to bring
all four tires back on the ground. As you approach the
crest of the hill ease off the throttle and slowly proceed
over the top. If the wheels start to slip as you approach
the crest of a hill, ease off the accelerator and maintain
headway by turning the steering wheel no more than
a 1/4 turn quickly back and forth. This will provide a
freshbiteinto the surface and will usually provide
enough traction to complete the climb. If you do not
make it to the top, place the vehicle in REVERSE and
back straight down the grade using engine resistance
along with the vehicle brakes.

WARNING!
DO NOT use a tire, wheel size or rating other than
that specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspension
dimensions and performance characteristics, result-
ing in changes to steering, handling, and braking of
your vehicle. This can cause unpredictable handling
and stress to steering and suspension components.
You could lose control and have an accident resulting
in serious injury or death. Use only the tire and
wheel sizes with load ratings approved for your
vehicle.
WARNING!
•NEVER use a tire with a smaller load index or
capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load
index could result in tire overloading and failure.
You could lose control and have an accident.
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer
readings.

•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System — If Equipped
This 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 lev-
els. 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 Telltale Light
The Tire Pressure Monitoring Telltale Light will illumi-
nate in the instrument cluster, and an audible chime will
be activated when one or more of the four active road tire
pressures 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 Monitor-
ing Light will extinguish once the updated tire pressures
have been received. The vehicle may need to be driven
for up to 10 minutes above 15 mph (25 km/h) to receive
this information.
