or gravel conditions and more wheel spin than ESP
would normally allow is required to gain traction. To
turn ESP on again, momentarily depress theESP Control
Switch. This will restore the normal “ESP On” mode of
operation.NOTE:To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand, or
gravel, it may be desirable to switch to the “Partial Off”
mode by pressing the ESP switch. Once the situation
requiring ESP to be switched to the “Partial Off” mode is
overcome, turn ESP back on by momentarily depressing
the “ESP Control Switch”. This may be done while the
vehicle is in motion.
Full Off (4WD Models Only)
This mode is intended for off-highway or off-road use
when ESP stability features could inhibit vehicle maneu-
verability due to trail conditions. This mode is entered by
depressing and holding the “ESP Control Switch” for 5
seconds when the vehicle is stopped and the engine is
running. After 5 seconds, the “ESP/TCS Indicator Light”
will illuminate, and theESP OFFmessage will appear in
the Electronic Vehicle Information Center (EVIC). Refer
to “Electronic Vehicle Information Center (EVIC)” in
Section 4 of this manual.

Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
TIRE CHAINS
Certain models have sufficient tire-to-body clearance to
allow use of tire chains.Install chains on rear tires only.
Follow these recommendations to guard against damage
and excessive tire and chain wear:
•Do not install tire chains or traction devices on ve-
hicles with larger than P235/65R17 size tires. Tires
larger than this may not provide sufficient body
clearance with chains or other traction devices.
•Use SAE class “S” tire chains or traction devices only.
•Follow tire chain manufacturer’s instructions for
mounting chains.
•Install chains snugly and tighten after 1/2 mile (1 km)
of driving.
•Do notexceed 35 mph (56 km/h), unless otherwise
specified by the chain manufacturer.
•Drive cautiously, avoiding large bumps, potholes and
extreme driving maneuvers.
TIRE ROTATION RECOMMENDATIONS
Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, handling,
and braking functions. For these reasons, they wear at
unequal rates, and develop irregular wear patterns.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with
aggressive tread designs such as those on On/Off Road
type tires. Rotation will increase tread life, help to main-
tain mud, snow, and wet traction levels, and contribute to
a smooth, quiet ride.
