10 mph (16 km/h).
Electronic Sway Bar Disconnect — If
Equipped
Your vehicle may be equipped with an elec -
tronic disconnecting stabilizer/sway bar. This
system allows greater front suspension travel
in off-road situations. This system is controlled by the SWAY BAR
switch located on the instrument panel (to
the right of the steering column).
SWAY BAR Switch
Push the SWAY BAR switch to activate the
system. Push the switch again to deactivate
the system. The “Sway Bar Indicator Light”
(located in the instrument cluster) will illu -
minate when the bar is disconnected. The
“Sway Bar Indicator Light” will flash during
activation transition, or when activation
conditions are not met. The stabilizer/sway
bar should remain in on-road mode during
normal driving conditions. To disconnect the stabilizer/sway bar, shift to
either 4H or 4L and push the SWAY BAR
switch to obtain the off-road position. Refer
to “Four-Wheel Drive Operation” in this
section for further information. The “Sway
Bar Indicator Light” will flash until the stabi
-
lizer/sway bar has been fully disconnected.
WARNING!
Ensure the stabilizer/sway bar is
reconnected before driving on hard
surfaced roads or at speeds above 18 mph
(29 km/h); a disconnected stabilizer/sway
bar may contribute to the loss of vehicle
control, which could result in serious
injury. Under certain circumstances, the
front stabilizer/sway bar enhances vehicle
stability and assists with vehicle control.
The system monitors vehicle speed and
will attempt to reconnect the stabilizer/
sway bar at speeds over 18 mph (29 km/
h). This is indicated by a flashing or solid
“Sway Bar Indicator Light.” Once vehicle
speed is reduced below 14 mph (22 km/
h), the system will once again attempt to
return to off-road mode.

FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand
or snow, it can often be moved using a
rocking motion. Turn the steering wheel right
and left to clear the area around the front
wheels. For vehicles with automatic trans-
mission, push and hold the lock button on
the gear selector. Then, shift back and forth
between DRIVE (D) and REVERSE (R), while
gently pressing the accelerator. Use the least
amount of accelerator pedal pressure that
will maintain the rocking motion, without
spinning the wheels or racing the engine.
NOTE:
For vehicles with automatic transmission:
Shifts between DRIVE and REVERSE can
only be achieved at wheel speeds of
5 mph (8 km/h) or less. Whenever the
transmission remains in NEUTRAL (N) for
more than two seconds, you must press
the brake pedal to engage DRIVE or
REVERSE.
Push the “ESC OFF” switch, to place the
Electronic Stability Control (ESC) system
in “Partial Off” mode, before rocking the
vehicle. Refer to “Electronic Brake Control
System” in “Safety” in your Owner’s Manual for further details. Once the
vehicle has been freed, push the “ESC
OFF” switch again to restore “ESC On”
mode.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause damage, or even failure,
of the axle and tires. A tire could explode
and injure someone. Do not spin your
vehicle's wheels faster than 30 mph
(48 km/h) or for longer than 30 seconds
continuously without stopping when you
are stuck and do not let anyone near a
spinning wheel, no matter what the speed.
CAUTION!
Racing the engine or spinning the wheels
may lead to transmission overheating
and failure. Allow the engine to idle with
the transmission in NEUTRAL for at
least one minute after every five
rocking-motion cycles. This will mini
-
mize overheating and reduce the risk of
clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
When “rocking” a stuck vehicle by
shifting between DRIVE/SECOND GEAR
and REVERSE, do not spin the wheels
faster than 15 mph (24 km/h), or drive -
train damage may result.
Revving the engine or spinning the
wheels too fast may lead to transmission
overheating and failure. It can also
damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service. If the transmission and drivetrain are oper-
able, disabled vehicles may also be towed as described under “Recreational Towing” in the “Starting And Operating” section.

Proper towing or lifting equipment is required to
prevent damage to your vehicle. Use only tow bars
and other equipment designed for this purpose,
following equipment manufacturer’s instructions.
Use of safety chains is mandatory. Attach a tow
bar or other towing device to main structural
members of the vehicle, not to bumpers or associ -
ated brackets. State and local laws regarding vehi -
cles under tow must be observed.

If you must use the accessories (wipers,
defrosters, etc.) while being towed, the igni -
tion must be in the ON/RUN position, not the
ACC position. If the vehicle's battery is discharged, refer to
“Manual Park Release” in this chapter for
instructions on shifting the automatic trans
-
mission out of PARK in order to move the
vehicle.

SERVICING AND MAINTENANCE
236
(Continued)
NOTE:
Wheel Valve Stem must be replaced as well
when installing new tires due to wear and
tear in existing tires.
Keep dismounted tires in a cool, dry place
with as little exposure to light as possible.
Protect tires from contact with oil, grease,
and gasoline.
Replacement Tires
The tires on your new vehicle provide a
balance of many characteristics. They should
be inspected regularly for wear and correct
cold tire inflation pressures. The manufac-
turer strongly recommends that you use tires
equivalent to the originals in size, quality
and performance when replacement is
needed. Refer to the paragraph on “Tread
Wear Indicators” in this section. Refer to the
Tire and Loading Information placard or the
Vehicle Certification Label for the size desig -
nation of your tire. The Load Index and
Speed Symbol for your tire will be found on
the original equipment tire sidewall.
It is recommended to replace the two front
tires or two rear tires as a pair. Replacing just
one tire can seriously affect your vehicle’s handling. If you ever replace a wheel, make
sure that the wheel’s specifications match
those of the original wheels.
It is recommended you contact an authorized
tire dealer or original equipment dealer with
any questions you may have on tire specifica
-
tions or capability. Failure to use equivalent
replacement tires may adversely affect the
safety, handling, and ride of your vehicle. WARNING!
Do not use a tire, wheel size, load rating,
or speed rating other than that specified
for your vehicle. Some combinations of
unapproved tires and wheels may change
suspension dimensions and performance
characteristics, resulting 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 a collision resulting in
serious injury or death. Use only the tire
and wheel sizes with load ratings
approved for your vehicle.
Never use a tire with a smaller load index
or capacity, other than what was origi -
nally 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 a collision.
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.
