Tire Terminology and Definitions
Air Pressure:The amount of air inside the tire
pressing outward on each square inch of the tire.
Air pressure is expressed in pounds per square
inch (psi) or kilopascal (kPa).
Accessory Weight:This means the combined
weight of optional accessories. Some examples of
optional accessories are, automatic transmission,
power steering, power brakes, power windows,
power seats, and air conditioning.
Aspect Ratio:The relationship of a tire's height
to its width.
Belt:A rubber coated layer of cords that is
located 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.
Bias Ply Tire:A pneumatic tire in which the plies
are laid at alternate angles less than 90 degrees
to the centerline of the tread.
Cold Tire Pressure:The amount of air pressure
in a tire, measured in pounds per square inch (psi)
or kilopascals (kPa) before a tire has built up heat
from driving. SeeInflation - Tire Pressureon
page 7!65.
Curb Weight:The weight of a motor vehicle with
standard and optional equipment including the
maximum capacity of fuel, oil, and coolant, but
without passengers and cargo.
DOT Markings:A code molded into the sidewall
of a tire signifying that the tire is in compliance
with the U.S. Department of Transportation (DOT)
motor vehicle safety standards. The DOT code
includes the Tire Identification Number (TIN), an
alphanumeric designator which can also identify
the tire manufacturer, production plant, brand, and
date of production.
GVWR:Gross Vehicle Weight Rating. See
Loading the Vehicleon page 6!32.
GAWR FRT:Gross Axle Weight Rating for the
front axle. SeeLoading the Vehicleon page 6!32.
GAWR RR:Gross Axle Weight Rating for the rear
axle. SeeLoading the Vehicleon page 6!32.

Inflation - Tire Pressure
If your vehicle is a Two-mode Hybrid, see the
Two-mode Hybrid manual for more information.
Tires need the correct amount of air pressure to
operate effectively.
Notice:Do not let anyone tell you that
under!inflation or over!inflation is all right.
It is not. If your tires do not have enough air
(under!inflation), you can get the following:
.Too much flexing
.Too much heat
.Tire overloading
.Premature or irregular wear
.Poor handling
.Reduced fuel economy
If your tires have too much air (over!inflation),
you can get the following:
.Unusual wear
.Poor handling
.Rough ride
.Needless damage from road hazards
A vehicle specific Tire and Loading Information
label is attached to your vehicle. This label shows
your vehicle's original equipment tires and the
correct inflation pressures for your tires when they
are cold. The recommended cold tire inflation
pressure, shown on the label, is the minimum
amount of air pressure needed to support your
vehicle's maximum load carrying capacity.
For additional information regarding how much
weight your vehicle can carry, and an example of
the Tire and Loading Information label, see
Loading the Vehicleon page 6!32. How you load
your vehicle affects vehicle handling and ride
comfort. Never load your vehicle with more weight
than it was designed to carry.
When to Check
Check your tires once a month or more.
Do not forget to check the pressure of the spare
tire. SeeSpare Tireon page 7!98for additional
information.

Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radioand sensor technology to check tire pressure levels.The TPMS sensors monitor the air pressure in yourvehicle's tires and transmit tire pressure readings to areceiver located in the vehicle.
Each tire, including the spare (if provided), should bechecked monthly when cold and inflated to the inflationpressure recommended by the vehicle manufactureron the vehicle placard or tire inflation pressure label.(If your vehicle has tires of a different size than the sizeindicated on the vehicle placard or tire inflation pressurelabel, you should determine the proper tire inflationpressure for those tires.)
As an added safety feature, your vehicle has beenequipped with a tire pressure monitoring system(TPMS) that illuminates a low tire pressure telltale whenone or more of your tires is significantly under!inflated.
Accordingly, when the low tire pressure telltaleilluminates, you should stop and check your tires assoon as possible, and inflate them to the properpressure. Driving on a significantly under!inflated tirecauses the tire to overheat and can lead to tire failure.Under!inflation also reduces fuel efficiency and tiretread life, and may affect the vehicle's handling andstopping ability.
Please note that the TPMS is not a substitute for propertire maintenance, and it is the driver's responsibility tomaintain correct tire pressure, even if under!inflationhas not reached the level to trigger illumination of theTPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMSmalfunction indicator to indicate when the system isnot operating properly. The TPMS malfunction indicatoris combined with the low tire pressure telltale. Whenthe system detects a malfunction, the telltale will flashfor approximately one minute and then remaincontinuously illuminated. This sequence will continueupon subsequent vehicle start!ups as long as themalfunction exists.
When the malfunction indicator is illuminated, thesystem may not be able to detect or signal low tirepressure as intended. TPMS malfunctions may occurfor a variety of reasons, including the installation ofreplacement or alternate tires or wheels on the vehiclethat prevent the TPMS from functioning properly.Always check the TPMS malfunction telltale afterreplacing one or more tires or wheels on your vehicle toensure that the replacement or alternate tires andwheels allow the TPMS to continue to function properly.

First Engine Oil Change After Every
80 000 km/50,000 Miles
.Engine air cleaner filter replacement. SeeEngineAir Cleaner/Filter on page 7!22.
.Automatic transmission fluid and filter change(severe service) for vehicles mainly driven in heavycity traffic in hot weather, in hilly or mountainousterrain, when frequently towing a trailer, or used fortaxi, police, or delivery service. SeeAutomaticTransmission Fluid on page 7!24.
.Four!wheel drive only: Transfer case fluid change(severe service) for vehicles mainly driven whenfrequently towing a trailer, or used for taxi, police,or delivery service. Check vent hose at transfercase for kinks and proper installation. Check to besure vent hose is unobstructed, clear, and free of
debris. During any maintenance, if a power washeris used to clean mud and dirt from the underbody,care should be taken to not directly spray thetransfer case output seals. High pressure watercan overcome the seals and contaminate thetransfer case fluid. Contaminated fluid willdecrease the life of the transfer case and shouldbe replaced.
.Evaporative control system inspection. Check allfuel and vapor lines and hoses for proper hook!up,routing, and condition. Check that the purge valve,if the vehicle has one, works properly. Replace asneeded.An Emission Control Service. The U.S.Environmental Protection Agency or the CaliforniaAir Resources Board has determined that thefailure to perform this maintenance item will notnullify the emission warranty or limit recall liabilityprior to the completion of the vehicle's useful life.We, however, urge that all recommendedmaintenance services be performed at theindicated intervals and the maintenance berecorded.
