466 SERVICING AND MAINTENANCE
(Continued)Tire Rotation Recommendations
Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, driving, and
braking functions. For these reasons, they wear at unequal
rates.
These effects can be reduced by timely rotation of tires. The
benefits of rotation are especially worthwhile with aggres -
sive tread designs such as those on On/Off Road type tires.
Rotation will increase tread life, help to maintain mud, snow,
and wet traction levels, and contribute to a smooth, quiet
ride.WARNING!
Using tires of different size and type (M+S, Snow)
between front and rear axles can cause unpredictable
handling. You could lose control and have a collision.
CAUTION!
To avoid damage to your vehicle or tires, observe the
following precautions:
• Because of restricted traction device clearance between
tires and other suspension components, it is important
that only traction devices in good condition are used.
Broken devices can cause serious damage. Stop the
vehicle immediately if noise occurs that could indicate
device breakage. Remove the damaged parts of the
device before further use.
• Install device as tightly as possible and then retighten
after driving about ½ mile (0.8 km).
• Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns and large
bumps, especially with a loaded vehicle.
• Do not drive for a prolonged period on dry pavement. • Observe the traction device manufacturer’s instruc -
tions on the method of installation, operating speed,
and conditions for use. Always use the suggested oper -
ating speed of the device manufacturer’s if it is less
than 30 mph (48 km/h).
• Do not use traction devices on a compact spare tire. CAUTION! (Continued)

SERVICING AND MAINTENANCE 467
Refer to the “Maintenance Plan” for the proper maintenance
intervals. More frequent rotation is permissible if desired.
The reasons for any rapid or unusual wear should be
corrected prior to rotation being performed.
Tire Rotation
NOTE:
On Canadian vehicles only, if your vehicle is equipped with
All-Season type tires on the front and On/Off Road type tires
mounted on the rear, do not use a front to back rotation
pattern. Instead, rotate your tires side to side at the recom -
mended intervals. Dual Rear Wheels
Tire Rotation
The tires used on dual wheel assemblies should be matched
for wear to prevent overloading one tire in a set. To check if
tires are even, lay a straight edge across all four tires. The
straight edge should touch all the tires. 7

Torque Specifications
**Use only your authorized dealer recommended lug nuts/
bolts and clean or remove any dirt or oil before tightening.
Inspect the wheel mounting surface prior to mounting the
tire and remove any corrosion or loose particles.
NOTE:
Dual wheels are flat mounted, center piloted. The lug nuts
are a two-piece assembly. When the tires are being rotated or
replaced, clean these lug nuts and add two drops of oil at the
interface between the hex and the washer. Ensure that the
socket is fully engaged on the lug nut/bolt (do not insert it
half way). Oil Interface Location
Do not oil wheel studs. For chrome wheels, do not substitute
with chrome plated wheel nuts.Lug Nut/Bolt

gation or audio screen appears again. When the vehicle is shifted out of REVERSE (with camera delay turned ON), the rear
view image with dynamic grid lines will be displayed for up to ten seconds after shifting out of REVERSE unless the forward
vehicle speed exceeds 8 mph (12 km/h), the transmission is shifted into PARK or the ignition is switched to the OFF position.
