Sidewall
The portion of a tire between thetread and the bead.
Speed Rating
An alphanumeric code assigned to a
tire indicating the maximum speed at

Traction
The friction between the tire and the
road surface. The amount of grip pro-vided.
Tread
The portion of a tire that comes intocontact with the road.
Treadwear Indicators
Narrow bands, sometimes called

Exterior care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warningand caution statements that appearon the label.
Protecting your vehicle's finish
When using high-pressure wash-
ers, make sure to maintain suffi-
cient distance from the vehicle.
Insufficient clearance or excessivepressure can lead to component
damage or water penetration.
Do not spray the camera, sensors or its surrounding area directly with
a high pressure washer. Shock
applied from high pressure water
may cause the device to not oper-
ate normally.
Do not bring the nozzle tip close to boots (rubber or plastic covers)or
connectors as they may be dam-
aged if they come into contact with
high pressure water.
Do not use any high-pressure noz- zles, which induce either one-direct
water stream or water swirling.
Protecting your vehicle's finish
Washing
To help protect your vehicle’s finish
from rust and deterioration, wash itthoroughly and frequently at least
once a month with lukewarm or cold
water.
If you use your vehicle for off-road
driving, you should wash it after each
off-road trip. Pay special attention to
the removal of any accumulation of
salt, dirt, mud, and other foreign
materials. Make sure the drain holes
in the lower edges of the doors and
rocker panels are kept clear andclean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar
deposits can damage your vehicle’s
finish if not removed immediately.
Even prompt washing with plain
water may not completely remove all
these deposits. A mild soap, safe for
use on painted surfaces, should beused. After washing, rinse the vehicle thor-
oughly with lukewarm or cold water.
Do not allow soap to dry on the fin-ish.
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water before getting on the
road. If braking performance is
impaired, dry the brakes by
applying them lightly while
maintaining a slow forwardspeed.

Maintenance
Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may
collect on the underbody. If these
materials are not removed, acceler-
ated rusting can occur on underbody
parts such as the fuel lines, frame,
floor pan and exhaust system, even
though they have been treated with
rust protection.
Thoroughly flush the vehicle under-
body and wheel openings with luke-
warm or cold water once a month,
after off-road driving and at the end
of each winter. Pay special attentionto these areas because it is difficult
to see all the mud and dirt. It will do
more harm than good to wet down
the road grime without removing it.
The lower edges of doors, rocker
panels, and frame members have
drain holes that should not be
allowed to clog with dirt; trapped
water in these areas can cause rust-ing.
Aluminum wheel maintenance
The aluminum wheels are coated
with a clear protective finish.
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water. If braking performance
is impaired, dry the brakes by
applying them lightly while
maintaining a slow forwardspeed.WARNING
Do not use abrasive cleaner,
polishing compound, solvent,
or wire brushes on aluminumwheels.
Clean the wheel when it has cooled.
Use only a mild soap or neu-
tral detergent, and rinse thor-
oughly with water. Also, cleanthe wheels after driving on
salted roads.
Do not wash the wheels with high-speed car wash brushes.
Do not use any cleaners con- taining acid or alkaline deter-
gents.
