Speed Rating:An alphanumeric
code assigned to a tire indicating
the maximum speed at which a
tire can operate.
Traction
:The friction between
the tire and the road surface.
The amount of grip provided.
Tread
:The portion of a tire that
comes into contact with the road.
Treadwear Indicators
:Narrow
bands, sometimes called wear
bars, that show across the tread
of a tire when only 1/16 inch
(1.6 mm) of tread remains.
SeeWhen It Is Time for New
Tires on page 9-62.
UTQGS (Uniform Tire Quality
Grading Standards)
:A tire
information system that provides
consumers with ratings for a
tire’s traction, temperature,
and treadwear. Ratings are
determined by tire manufacturers
using government testingprocedures. The ratings are
molded into the sidewall of the
tire. SeeUniform Tire Quality
Grading on page 9-65.
Vehicle Capacity Weight
:The number of designated
seating positions multiplied by
150 lbs (68 kg) plus the rated
cargo load. SeeVehicle Load
Limits on page 8-12.
Vehicle Maximum Load on the
Tire
:Load on an individual tire
due to curb weight, accessory
weight, occupant weight, and
cargo weight.
Vehicle Placard
:A label
permanently attached to a
vehicle showing the vehicle’s
capacity weight and the original
equipment tire size and
recommended inflation pressure.
See “Tire and Loading
Information Label” underVehicle
Load Limits on page 8-12.
Tire Pressure
Tires need the correct amount
of air pressure to operate
effectively.
Notice:Do not let anyone
tell you that under-in ation or
over-in ation is all right. It is
not. If your tires do not have
enough air (under-in ation),
you can get the following:
Too much exing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air
(over-in ation), you can get
the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road
hazards
9-54 Vehicle Care

Tire Pressure for
High-Speed Operation
{WARNING
Driving at high speeds, 100 mph
(160 km/h) or higher, puts an
additional strain on tires. Sustained
high-speed driving causes
excessive heat build up and
can cause sudden tire failure.
You could have a crash and you
or others could be killed. Some
high-speed rated tires require
inflation pressure adjustment for
high speed operation. When speed
limits and road conditions are such
that a vehicle can be driven at high
speeds, make sure the tires are
rated for high speed operation, in
excellent condition, and set to the
correct cold tire inflation pressure
for the vehicle load.Vehicles with 245/45ZR20 103Y,
P245/50ZR19 104W and
275/40ZR20 106Y size tires,
have tires capable of high speed
use. Make sure the tires are inflated
to the recommended cold inflation
pressures before operating the
vehicle at speeds over 100 mph
(160 km/h). SeeVehicle Load Limits
on page 8-12andTire Pressure on
page 9-54.
Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your vehicle’s tires
and transmit tire pressure readings
to a receiver located in the vehicle.
Each tire, including the spare
(if provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on thevehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, you
should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS) that illuminates a low tire
pressure telltale when one or
more of your tires is significantly
under-inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them
to the proper pressure. Driving on
a significantly under-inflated tire
causes the tire to overheat and can
lead to tire failure. Under-inflation
also reduces fuel efficiency and
tire tread life, and may affect the
vehicle’s handling and stopping
ability.
9-56 Vehicle Care

Windshield and Wiper Blades
Clean the outside of the windshield
with glass cleaner.
Clean the rubber blades using a lint
free cloth or paper towel soaked with
windshield washer fluid or a mild
detergent. Wash the windshield
thoroughly when cleaning the blades.
Bugs, road grime, sap, and a buildup
of vehicle wash/wax treatments may
cause wiper streaking. Replace the
wiper blades if they are worn or
damaged.
Wipers can be damaged by:
•Extreme dusty conditions
•Sand and salt
•Heat and sun
•Snow and ice, without proper
removal
Tires
Use a stiff brush with tire cleaner to
clean the tires.
Notice:Using petroleum-based
tire dressing products on the
vehicle may damage the paint
nish and/or tires. When applying
a tire dressing, always wipe off
any overspray from all painted
surfaces on the vehicle.
Sheet Metal Damage
If the vehicle is damaged and
requires sheet metal repair or
replacement, make sure the body
repair shop applies anti-corrosion
material to parts repaired or
replaced to restore corrosion
protection.
Original manufacturer replacement
parts will provide the corrosion
protection while maintaining
the vehicle warranty.
Finish Damage
Any stone chips, fractures or deep
scratches in the finish should be
repaired right away. Bare metal will
corrode quickly and may develop into
major repair expense.
Minor chips and scratches can be
repaired with touch-up materials
available from your dealer/retailer.
Larger areas of finish damage can be
corrected in your dealer’s/retailer’s
body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow
removal and dust control can collect
on the underbody. If these are not
removed, corrosion and rust can
develop on the underbody parts such
as fuel lines, frame, floor pan, and
exhaust system even though they
have corrosion protection.

General Information
Notice:Maintenance
intervals, checks, inspections,
recommended uids, and
lubricants are necessary to
keep this vehicle in good
working condition. Damage
caused by failure to follow
scheduled maintenance might
not be covered by the vehicle
warranty.
Proper vehicle maintenance helps to
keep the vehicle in good working
condition, improves fuel economy,
and reduces vehicle emissions
for better air quality.
Because of all the different ways
people use vehicles, maintenance
needs vary. The vehicle might need
more frequent checks and services.
Please read the information under
Scheduled Maintenance. To keep
the vehicle in good condition, see
your dealer/retailer.The maintenance schedule is for
vehicles that:•carry passengers and cargo
within recommended limits on
the Tire and Loading Information
label. SeeVehicle Load Limits
on page 8-12.
•are driven on reasonable road
surfaces within legal driving
limits.
•use the recommended fuel.
