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. See
When It Is Time for New Tires on
page 5-51.
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 testing
procedures. The ratings are
molded into the sidewall of the
tire. SeeUniform Tire Quality
Grading on page 5-54.Vehicle Capacity Weight
:The
number of designated seating
positions multiplied by 150 lbs
(68 kg) plus the rated cargo load.
SeeLoading the Vehicle on
page 4-18.
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 in ation pressure.
See “Tire and Loading
Information Label” under

page 4-18.
In ation - 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
A vehicle speci c Tire and
Loading Information label is
attached to your vehicle.

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 in ated to the
in ation pressure recommended by
the vehicle manufacturer on the
vehicle placard or tire in ation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire in ation pressure label, you
should determine the proper tire
in ation 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 signi cantly under-in ated.Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and in ate them to
the proper pressure. Driving on a
signi cantly under-in ated tire
causes the tire to overheat and can
lead to tire failure. Under-in ation
also reduces fuel efficiency and tire
tread life, and may affect the
vehicle’s handling and stopping
ability.
Please note that the TPMS is not
a substitute for proper tire
maintenance, and it is the driver’s
responsibility to maintain correct
tire pressure, even if under-in ation
has not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been
equipped with a TPMS malfunction
indicator to indicate when the
system is not operating properly.
The TPMS malfunction indicator
is combined with the low tire
pressure telltale. When thesystem detects a malfunction, the
telltale will ash for approximately
one minute and then remain
continuously illuminated. This
sequence will continue upon
subsequent vehicle start-ups as
long as the malfunction exists.
When the malfunction indicator is
illuminated, the system may
not be able to detect or signal low
tire pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires
or wheels on the vehicle that prevent
the TPMS from functioning
properly. Always check the TPMS
malfunction telltale after replacing
one or more tires or wheels on your
vehicle to ensure that the
replacement or alternate tires and
wheels allow the TPMS to continue
to function properly.

See Engine Coolant on page 5-20
for what to use. Inspect hoses. Clean
radiator, condenser, pressure cap,
and filler neck. Pressure test the
cooling system and pressure cap.
(j)A fluid loss in any vehicle system
could indicate a problem. Have
the system inspected and repaired
and the fluid level checked. Add
fluid if needed.
(k)Or every 12 months, whichever
occurs first. If driving regularly
under dusty conditions, the filter may
require replacement more often.
(l)If driving regularly under dusty
conditions, inspect the filter at each
engine oil change.
(m)Visually inspect belt for fraying,
excessive cracks, or obvious
damage. Replace belt if necessary.
(n)Vehicles using DOT-4 brake
fluid only: Drain, flush, and
refill brake hydraulic system at a
regular maintenance service (IorII)
every two years. This service can
be complex; you should haveyour dealer/retailer perform this
service. See Brakes on page 5-25
andRecommended Fluids and
Lubricants on page 6-11.
Owner Checks and
Services
These owner checks and services
should be performed at the intervals
speci ed to help ensure vehicle
safety, dependability, and emission
control performance. Your dealer/
retailer can assist with these checks
and services.
Be sure any necessary repairs are
completed at once. Whenever
any uids or lubricants are added to
the vehicle, make sure they are
the proper ones, as shown in
Recommended Fluids and
Lubricants on page 6-11.
At Each Fuel Fill
It is important to perform these
underhood checks at each fuel fill.
Engine Oil Level Check
Notice:It is important to check
the engine oil regularly and
keep it at the proper level. Failure
to keep the engine oil at the
proper level can cause damage to
the engine not covered by the
vehicle warranty.
Check the engine oil level and add
the proper oil if necessary. See
Engine Oil on page 5-11.
Engine Coolant Level Check
Check the engine coolant level
and add DEX-COOL®coolant
mixture if necessary. SeeEngine
Coolant on page 5-20.
