Belt:Arubbercoatedlayerof
cords between the plies and the
tread. Cords may be made from
steel or other reinforcing
materials.
Bead:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim.

in which the plies are laid at
alternate angles less than
90 degrees to the centerline of
the tread.

amount of air pressure in a tire,
measured in kPa (kilopascal)
or psi (pounds per square inch)
before a tire has built up heat
from driving. SeeTire
Pressure0260.

Vehicle Capacity Weight:The
number of designated seating
positions multiplied by
68 kg (150 lb) plus the rated
cargo load. SeeVehicle Load
Limits0171.
Vehicle Maximum Load on the
Tire:Load on an individual tire
due to curb weight, accessory
weight, occupant weight, and

Vehicle Placard:Alabel
permanently attached to a
vehicle showing the vehicle
capacity weight and the original
equipment tire size and
recommended inflation pressure.
See“Tire and Loading
Information Label”underVehicle
Load Limits0171.
Tire Pressure
Tires need the correct amount of
air pressure to operate
effectively.
Caution
Neither tire underinflation nor
overinflation is good.
Underinflated tires, or tires
that do not have enough air,
can result in:
.Tire overloading and
overheating which could
lead to a blowout.
.Premature or
irregular wear.
.Poor handling.
.Reduced fuel economy.
Overinflated tires, or tires that
have too much air, can
result in:
.Unusual wear.
(Continued)
Caution (Continued)
.Poor handling.
.Rough ride.
.Needless damage from
road hazards.
The Tire and Loading
Information label on the vehicle
indicates the original equipment
tires and the correct cold tire
inflation pressures. The
recommended pressure is the
minimum air pressure needed to
support the vehicle's maximum
load carrying capacity.
For additional information
regarding how much weight the
vehicle can carry, and an
example of the Tire and Loading
Information label, seeVehicle
Load Limits0171.Howthe
vehicle is loaded affects vehicle
handling and ride comfort. Never

lead to tire failure. Under-inflationalso reduces fuel efficiency and tiretread life, and may affect thevehicle's handling and stoppingability.
Please note that the TPMS is not asubstitute for proper tiremaintenance, and it is the driver'sresponsibility to maintain correct tirepressure, even if under-inflation hasnot reached the level to triggerillumination of the TPMS low tirepressure telltale.
Yo u r v e h i c l e h a s a l s o b e e nequipped with a TPMS malfunctionindicator to indicate when thesystem is not operating properly.The TPMS malfunction indicator iscombined with the low tire pressuretelltale. When the system detects amalfunction, the telltale will flash forapproximately one minute and thenremain continuously illuminated.This sequence will continue uponsubsequent vehicle start-ups aslong as the malfunction exists.
When the malfunction indicator isilluminated, the system may not beable to detect or signal low tire
pressure as intended. TPMSmalfunctions may occur for a varietyof reasons, including the installationof replacement or alternate tires orwheels on the vehicle that preventthe TPMS from functioning properly.Always check the TPMS malfunctiontelltale after replacing one or moretires or wheels on your vehicle toensure that the replacement oralternate tires and wheels allow theTPMS to continue to functionproperly.
SeeTire Pressure MonitorOperation0262.
SeeRadio FrequencyStatement0322.
Tire Pressure Monitor
Operation
This vehicle may have a TirePressure Monitor System (TPMS).The TPMS is designed to warn thedriver when a low tire pressurecondition exists. TPMS sensors aremounted onto each tire and wheelassembly, excluding the spare tireand wheel assembly. The TPMSsensors monitor the air pressure in
the tires and transmit the tirepressure readings to a receiverlocated in the vehicle.
When a low tire pressure conditionis detected, the TPMS illuminatesthe low tire pressure warning lightlocated on the instrument cluster.If the warning light comes on, stopas soon as possible and inflate thetires to the recommended pressureshown on the Tire and LoadingInformation label. SeeVehicle LoadLimits0171.
AmessagetocheckthepressureinaspecifictiredisplaysintheDriverInformation Center (DIC). The lowtire pressure warning light and theDIC warning message come on ateach ignition cycle until the tires areinflated to the correct inflationpressure. If the vehicle has DICbuttons, tire pressure levels can beviewed. For additional information

290 Vehicle Care
Lamp covers are made of plastic,and some have a UV protectivecoating. Do not clean or wipe themwhile they are dry.
Do not use any of the following onlamp covers:
.Abrasive or caustic agents.
.Washer fluids and other cleaningagents in higher concentrationsthan suggested by themanufacturer.
.Solvents, alcohols, fuels,or other harsh cleaners.
.Ice scrapers or other hard items.
.Aftermarket appearance caps orcovers while the lamps areilluminated, due to excessiveheat generated.
Caution
Failure to clean lamps properly
can cause damage to the lamp
cover that would not be covered
by the vehicle warranty.
Caution
Using wax on low gloss black
finish stripes can increase the
gloss level and create a
non-uniform finish. Clean low
gloss stripes with soap and
water only.
Air Intakes
Clear debris from the air intakes,between the hood and windshieldwhen washing the vehicle.
Windshield and Wiper Blades
Clean the outside of the windshieldwith glass cleaner.
Clean rubber blades using a lint-freecloth or paper towel soaked withwindshield washer fluid or a milddetergent. Wash the windshieldthoroughly when cleaning theblades. Bugs, road grime, sap, andabuildupofvehiclewash/waxtreatments may cause wiperstreaking.
Replace the wiper blades if they areworn or damaged. Damage can becaused by extreme dustyconditions, sand, salt, heat, sun,snow, and ice.
Weatherstrips
Apply Dielectric silicone grease onweatherstrips to make them lastlonger, seal better, and not stick orsqueak. Lubricate weatherstrips atleast once a year. Hot, dry climatesmay require more frequentapplication. Black marks fromrubber material on painted surfacescan be removed by rubbing with aclean cloth. SeeRecommendedFluids and Lubricants0305.
Tires
Use a stiff brush with tire cleaner toclean the tires.
Caution
Using petroleum-based tire
dressing products on the vehicle
may damage the paint finish and/

292 Vehicle Care
Body Component Lubrication
Lubricate all key lock cylinders,hood hinges, liftgate hinges, and thefuel door hinge unless thecomponents are plastic. Applyingsilicone grease on weatherstripswith a clean cloth will make themlast longer, seal better, and not stickor squeak.
Underbody Maintenance
At least twice a year, spring and fall,use plain water to flush dirt anddebris from the vehicle's underbody.Yo u r d e a l e r o r a n u n d e r b o d y c a rwashing system can do this. If notremoved, rust and corrosion candevelop.
Do not directly power wash thetransfer case and/or front/rear axleoutput seals. High pressure watercan overcome the seals andcontaminate the fluid. Contaminatedfluid will decrease the life of thetransfer case and/or axles andshould be replaced.
Sheet Metal Damage
If the vehicle is damaged andrequires sheet metal repair orreplacement, make sure the bodyrepair shop applies anti-corrosionmaterial to parts repaired orreplaced to restore corrosionprotection.
Original manufacturer replacementparts will provide the corrosionprotection while maintaining thevehicle warranty.
Finish Damage
Quickly repair minor chips andscratches with touch-up materialsavailable from your dealer to avoidcorrosion. Larger areas of finishdamage can be corrected in yourdealer's body and paint shop.
Chemical Paint Spotting
Airborne pollutants can fall uponand attack painted vehicle surfacescausing blotchy, ring-shapeddiscolorations, and small, irregulardark spots etched into the paintsurface. See“Finish Care”previously in this section.
Interior Care
To p r e v e n t d i r t p a r t i c l e a b r a s i o n s ,regularly clean the vehicle's interior.Immediately remove any soils.Newspapers or dark garments cantransfer color to the vehicle’sinterior.
Use a soft bristle brush to removedust from knobs and crevices on theinstrument cluster. Using a mildsoap solution, immediately removehand lotions, sunscreen, and insectrepellent from all interior surfaces orpermanent damage may result.
Use cleaners specifically designedfor the surfaces being cleaned toprevent permanent damage. Applycleaners directly to the cleaningcloth. Do not spray cleaners on anyswitches or controls. Removecleaners quickly.
Before using cleaners, read andfollow to all safety instructions onthe label. While cleaning the interior,open the doors and windows to getproper ventilation.
