Treadwear Indicators:Narrow
bands, sometimes called wear
bars, that show across the tread
of a tire when only 1.6 mm (1/
16 in) of tread remains. See
When It Is Time for New Tires
0316.
UTQGS (Uniform Tire Quality
Grading Standards):Atire
information system that provides
consumers with ratings for a
tire's traction, temperature, and
treadwear. Ratings are
determined by tire
manufacturers using
government testing procedures.
The ratings are molded into the
sidewall of the tire. SeeUniform
Tire Quality Grading0319.
Vehicle Capacity Weight:The
number of designated seating
positions multiplied by
68 kg (150 lb) plus the rated
cargo load. SeeVehicle Load
Limits0226.
Vehicle Maximum Load on the
Tire:Load on an individual tire
due to curb weight, accessory
weight, occupant weight, and
cargo weight.
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 Limits0226.
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.
.Poor handling.
.Rough ride.
.Needless damage from
road hazards.

Vehicle Care 311
Vehicles with 245/40ZR19 98Y and275/35ZR19 100Y tires are capableof high speed use.
Make sure front tires of size 245/40ZR19 98Y are inflated to 310 kPa(45 psi) before operating the vehicleat speeds of 160 km/h (100 mph) orhigher.
Make sure rear tires of size 275/35ZR19 100Y are inflated to340 kPa (50 psi) before operatingthe vehicle at speeds of 160 km/h(100 mph) or higher.
Return the tires to therecommended cold tire inflationpressure when high-speed drivinghas ended. SeeVehicle Load Limits0226andTire Pressure0309.
Tire Pressure Monitor
System
The Tire Pressure Monitor System(TPMS) uses radio and sensortechnology to check tire pressurelevels. The TPMS sensors monitorthe air pressure in your tires andtransmit tire pressure readings to areceiver located in the vehicle.
Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflated tothe inflation pressure recommendedby the vehicle manufacturer on thevehicle placard or tire inflationpressure label. (If your vehicle hastires of a different size than the sizeindicated on the vehicle placard ortire inflation pressure label, youshould determine the proper tireinflation pressure for those tires.)
As an added safety feature, yourvehicle has been equipped with atire pressure monitoring system(TPMS) that illuminates a low tirepressure telltale when one or moreof your tires is significantlyunder-inflated.
Accordingly, when the low tirepressure telltale illuminates, youshould stop and check your tires assoon as possible, and inflate themto the proper pressure. Driving on asignificantly under-inflated tirecauses the tire to overheat and canlead to tire failure. Under-inflationalso reduces fuel efficiency and tire
tread 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 tirepressure as intended. TPMSmalfunctions may occur for a variety

340 Vehicle Care
Protecting Exterior Bright MetalMoldings
Caution
Failure to clean and protect the
bright metal moldings can result
in a hazy white finish or pitting.
This damage would not be
covered by the vehicle warranty.
The bright metal moldings on thevehicle are aluminum, chrome orstainless steel. To prevent damagealways follow these cleaninginstructions:
.Be sure the molding is cool tothe touch before applying anycleaning solution.
.Use only approved cleaningsolutions for aluminum, chromeor stainless steel. Somecleaners are highly acidic orcontain alkaline substances andcan damage the moldings.
.Always dilute a concentratedcleaner according to themanufacturer’sinstructions.
.Do not use cleaners that are notintended for automotive use.
.Use a nonabrasive wax on thevehicle after washing to protectand extend the molding finish.
Cleaning Exterior Lamps/
Lenses, Emblems, Decals, and
Stripes
Use only lukewarm or cold water, asoft cloth, and a car washing soapto clean exterior lamps, lenses,emblems, decals, and stripes.Follow instructions under "Washingthe Vehicle" previously in thissection.
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.

brushes. Damage could occur
and the repairs would not be
covered by the vehicle warranty.
Door Drain Holes
.Clear dirt and other foreignmaterials from the drain holes atthe bottom of the door panelswhich could trap water inside thepanels.
.Clean clogged drain holes.
.Avoid scratching the finish.
Brake System
Visually inspect brake lines andhoses for proper hook-up, binding,leaks, cracks, chafing, etc. Inspectdisc brake pads for wear and rotorsfor surface condition. Inspect drumbrake linings/shoes for wear orcracks. Inspect other brake parts,including drums, wheel cylinders,calipers, parking brake, mastercylinder, brake fluid reservoir,vacuum pipes, electric vacuumpump including bracket and venthose, if equipped.
Steering, Suspension, and
Chassis Components
Visually inspect steering,suspension, and chassiscomponents for damaged, loose,or missing parts or signs of wear atleast once a year.
Inspect power steering for properhook-up, binding, leaks, cracks,chafing, etc.
Visually check constant velocity jointboots and axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders,hood hinges, liftgate hinges, steelfuel door hinge, decklid springbushings, and power assist stephinges, unless the components areplastic. Applying silicone grease onweatherstrips with a clean cloth willmake them last longer, seal better,and not stick or squeak.
Underbody Maintenance
At least twice a year, spring and fall,use plain water to flush anycorrosive materials from theunderbody. Take care to thoroughlyclean any areas where mud andother debris can collect.
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.
