This device complies with RSS-210
of Industry Canada. Operation is
subject to the following two
conditions:
1. This device may not cause
interference.
2. This device must accept any
interference received, including
interference that may cause
undesired operation of the
device.
Changes or modi cations to this
system by other than an authorized
service facility could void
authorization to use this equipment.
Theft-Deterrent Feature
THEFTLOCK®is designed to
discourage theft of the vehicle’s radio
by learning a portion of the Vehicle
Identi cation Number (VIN). The
radio does not operate and LOCKED
displays if the radio is stolen or
moved to a different vehicle.When the when the ignition is in the
off position, a blinking red light on
the upper left side of the radio
indicates that THEFTLOCK
®
is armed.
Radio Reception
Frequency interference and static
can occur during normal radio
reception if items such as cell phone
chargers, vehicle convenience
accessories, and external electronic
devices are plugged into the
accessory power outlet. If there is
interference or static, unplug the item
from the accessory power outlet.
AM
The range for most AM stations is
greater than for FM, especially
at night. The longer range can cause
station frequencies to interfere
with each other. For better radio
reception, most AM radio stations
boost the power levels during
the day, and then reduce these
levels during the night. Static
can also occur when things likestorms and power lines interfere
with radio reception. When this
happens, try reducing the treble on
the radio.
FM Stereo
FM signals only reach about
10 to 40 miles (16 to 65 km).
Although the radio has a built-in
electronic circuit that automatically
works to reduce interference,
some static can occur, especially
around tall buildings or hills, causing
the sound to fade in and out.
XM™ Satellite Radio Service
XM Satellite Radio Service gives
digital radio reception from
coast-to-coast in the 48 contiguous
United States, and in Canada.
Just as with FM, tall buildings or hills
can interfere with satellite radio
signals, causing the sound to fade
in and out. In addition, traveling
or standing under heavy foliage,
bridges, garages, or tunnels
may cause loss of the XM signal for
a period of time.

Braking in Emergencies
ABS allows the driver to steer
and brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Brake Assist
This vehicle has a Brake Assist
feature designed to assist the driver
in stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied
the brake pedal in an attempt to
quickly stop or slow down the
vehicle. The stability system
hydraulic brake control module
increases brake pressure at each
corner of the vehicle until the
ABS activates. Minor brake pedal
pulsations or pedal movement
during this time is normal and the
driver should continue to applythe brake pedal as the driving
situation dictates The Brake Assist
feature will automatically disengage
when the brake pedal is released
or brake pedal pressure is quickly
decreased.
StabiliTrak®System
The vehicle has a vehicle stability
enhancement system called
StabiliTrak. It is an advanced
computer controlled system that
assists the driver with directional
control of the vehicle in difficult
driving conditions.
StabiliTrak activates when the
computer senses a discrepancy
between the intended path and the
direction the vehicle is actually
traveling. StabiliTrak selectively
applies braking pressure at any one
of the vehicle’s brakes to assist
the driver with keeping the vehicle
on the intended path.
When the vehicle is started and
begins to move, the system
performs several diagnostic checksto insure there are no problems.
The system may be heard or
felt while it is working. This is normal
and does not mean there is a
problem with the vehicle.
If cruise control is being used when
StabiliTrak activates, the cruise
control automatically disengages.
The cruise control can be
re-engaged when road conditions
allow. SeeCruise Control on
page 3-9.
If there is a problem detected with
StabiliTrak, a SERVICE STAB
SYS message displays on the Driver
Information Center (DIC). See
DIC Warnings and Messages on
page 3-37for more information.
When this message is displayed, the
system is not working. Adjust your
driving accordingly.
StabiliTrak comes on automatically
whenever the vehicle is started
and resets itself at each ignition
cycle. However, when the transfer
case is placed in Four-Wheel-Low
Lock mode, StabiliTrak is
4-6 Driving Your Vehicle
Page 190 of 382
Adjust your driving accordingly. See
DIC Warnings and Messages on
page 3-37for more information.
It is recommended to leave
the system on for normal driving
conditions, but it may be necessary
to turn the system off if the
vehicle is stuck in sand, mud, ice, or
snow, and it is necessary to
“rock” the vehicle to attempt to free
it. SeeIf Your Vehicle is Stuck
in Sand, Mud, Ice, or Snow
on page 4-33for more information.
To turn the system off, press and
release the TCS/StabiliTrak
®button.When TCS has been turned off, this
light comes on steady and TRAC
OFF appears on the DIC. This light
ashes when TCS is active.
Press and release the
TCS/StabiliTrak button again to turn
the system back on. The TRAC
OFF message then goes off. TCS
automatically comes on whenever
the vehicle is started and resets
itself at each ignition cycle.
Adding non-dealer/non-retailer
accessories can affect the vehicle’s
performance. SeeAccessories
and Modifications on page 5-3.
Locking Rear Axle
For vehicles with this feature,
additional traction can be obtained
from the rear wheels when
traveling in off-road situations such
as mud, snow, sand, steep hills
and uneven terrain.
The button used to turn this feature
on or off is located on the
instrument panel.
To lock the rear axle, do the
following:
1. Place the transfer case in the
4LO Lock mode. This is the
only mode which will allow
the rear axle to lock. See
Full-Time Four-Wheel Drive on
page 2-24for more information
regarding the transfer case
and 4LO Lock mode.

Driving in Water
{CAUTION
Driving through rushing water can
be dangerous. Deep water can
sweep your vehicle downstream
and you and your passengers
could drown. If it is only shallow
water, it can still wash away the
ground from under your tires, and
you could lose traction and roll
the vehicle over. Do not drive
through rushing water.
Heavy rain can mean ash ooding,
and ood waters demand extreme
caution.Find out how deep the water is
before driving through it. Do not
try it if it is deep enough to cover
the wheel hubs, axles, or exhaust
pipe — you probably will not get
through. Deep water can damage the
axle and other vehicle parts. The
vehicle is capable of depths up to
20 inches (50 cm). Know how to
judge whether the water is deeper
than this before proceeding into it.
If the water is not too deep, drive
slowly through it. At faster speeds,
water splashes on the ignition
system and the vehicle can stall.
Stalling can also occur if you get the
tailpipe under water. If the tailpipe
is under water, you will never
be able to start the engine. When
going through water, remember that
when the brakes get wet, it might
take longer to stop. SeeDriving
in Rain and on Wet Roads on
page 4-29.
After Off-Road Driving
Remove any brush or debris that
has collected on the underbody,
chassis, or under the hood. These
accumulations can be a re hazard.
After operation in mud or sand,
have the brake linings cleaned and
checked. These substances can
cause glazing and uneven braking.
Check the engine and oil coolers
for mud accumulation. Thoroughly
and carefully clean these devices to
allow proper cooling. Check the
body structure, steering, suspension,
wheels, tires, and exhaust system
for damage and check the fuel lines
and cooling system for any
leakage.
The vehicle requires more frequent
service due to off-road use.
Refer to the Maintenance Schedule
for additional information.

{CAUTION
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. The brakes will have
to do all the work of slowing down
and they could get so hot that
they would not work well. You
would then have poor braking or
even none going down a hill. You
could crash. Always have the
engine running and the vehicle in
gear when going downhill.
Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in your
own lane.
Top of hills: Be alert — something
could be in your lane (stalled car,
accident).
Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
SeeOff-Road Driving on page 4-13
for information about driving
off-road.
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or grip.
Wet ice can occur at about 32°F
(0°C) when freezing rain begins to
fall, resulting in even less traction.
Avoid driving on wet ice or in
freezing rain until roads can be
treated with salt or sand.
Drive with caution, whatever the
condition. Accelerate gently
so traction is not lost. Accelerating
too quickly causes the wheelsto spin and makes the surface
under the tires slick, so there is even
less traction.
Try not to break the fragile traction. If
you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.
TheTraction Control System (TCS)
on page 4-7improves the ability
to accelerate on slippery roads, but
slow down and adjust your driving
to the road conditions. When driving
through deep snow, turn off the
traction control system to help
maintain vehicle motion at lower
speeds.
TheAntilock Brake System (ABS)
on page 4-5improves vehicle
stability during hard stops on a
slippery roads, but apply the brakes
sooner than when on dry pavement.

Use the following procedure to tow
the vehicle:
1. Put the transmission in P (Park)
for an automatic transmission or
in 1 (First) for a manual
transmission.
2. Turn the engine off, but leave the
ignition in ACC/ACCESSORY.
3. Firmly set the parking brake.
4. Securely attach the vehicle being
towed to the tow vehicle.
{CAUTION
Shifting a full-time
four-wheel-drive vehicle’s
transfer case into N (Neutral)
can cause the vehicle to roll
even if the automatic transmission
is in P (Park) or the manual
transmission is in any gear. You
or others could be injured. Make
sure the parking brake is rmly
set before the transfer case is
shifted to N (Neutral).5. Shift the transfer case to
N (Neutral). SeeFull-Time
Four-Wheel Drive on page 2-24
for the proper procedure to
select the N (Neutral) position for
the vehicle.
6. Release the parking brake only
after the vehicle being towed is
rmly attached to the tow vehicle.
7. Make sure the ignition is in
ACC/ACCESSORY.
When towing the vehicle for
extended periods of time, start the
vehicle as often as possible to
prevent battery drain. This should
only be done when the tow
vehicle is parked.
After towing, see “Shifting Out of
NEUTRAL” underFull-Time
Four-Wheel Drive on page 2-24.
Dolly Towing
Notice:Dolly towing the vehicle
will damage drivetrain
components. Do not dolly tow the
vehicle.
The vehicle cannot be dolly towed.
If the vehicle must be towed
behind another vehicle, use the
dinghy towing procedure explained
previously.

When the system has calculated
that oil life has been diminished,
it indicates that an oil change
is necessary. A CHANGE OIL
message comes on. SeeDIC
Warnings and Messages on
page 3-37. Change the oil as soon
as possible within the next
600 miles (1 000 km). It is possible
that, if driving under the best
conditions, the oil life system might
not indicate that an oil change is
necessary for over a year. However,
the engine oil and lter must be
changed at least once a year and
at this time the system must be
reset. Your dealer/retailer has
trained people who will perform this
work using genuine parts and reset
the system. It is also important
to check the oil regularly and keep it
at the proper level.
If the system is ever reset
accidentally, the oil must be
changed at 3,000 miles (5 000 km)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.How to Reset the Engine Oil
Life System
The Engine Oil Life System
calculates when to change the
engine oil and lter based on vehicle
use. Whenever the oil is changed,
reset the system so it can calculate
when the next oil change is required.
If a situation occurs where the oil is
changed prior to a CHANGE OIL
message being turned on, reset the
system.
To reset the Engine Oil Life system:
1. With the engine off, turn the
ignition to ON/RUN.
2. Press and release the stem in
the lower center of the
instrument cluster until the OIL
LIFE message is displayed.
3. Once the alternating OIL LIFE
and RESET messages appear,
press and hold the stem until
several beeps sound. This
con rms that the oil life system
has been reset.
4. Turn the key to LOCK/OFF.If the CHANGE OIL message
comes back on when the vehicle is
started, the engine oil life system
has not reset. Repeat the procedure.
SeeDIC Warnings and Messages
on page 3-37.
What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer’s warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your own
oil, be sure to drain all the oil from the
lter before disposal. Never dispose
of oil by putting it in the trash, pouring
it on the ground, into sewers, or into
streams or bodies of water. Recycle
it by taking it to a place that collects
used oil.
