TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the “Tire Pressure
Low - Add Air” warning appears in the
vehicle information display, one or more of
your tires is significantly under-inflated.
The TPMS will activate only when the
vehicle is driven at speeds above 16 MPH
(25 km/h). Also, this system may not
detect a sudden drop in tire pressure (for
example a flat tire while driving).
For more details, see “Low tire pressure
warning light” (P.2-15),“Tire Pressure Mon-
itoring System (TPMS)” (P.5-4) and“Tire
Pressure Monitoring System (TPMS)” (P.6-
3).
Tire inflation pressure
Check the pressure of the tires
(including the spare) often and al- ways prior to long distance trips. The
recommended tire pressure specifi-
cations are shown on the Tire and
Loading Information label under the
“Cold Tire Pressure”
heading. The
Tire and Loading Information label is
affixed to the driver side center pillar.
Tire pressures should be checked
regularly because:
.Most tires naturally lose air over time.
.Tires can lose air suddenly whendriven over potholes or other
objects or if the vehicle strikes a
curb while parking.
The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle
has been parked for 3 or more hours,
or driven less than 1 mile (1.6 km) at
moderate speeds.
TPMS with Tire Inflation Indicator
provides visual and audible signals
outside the vehicle for inflating the
tires to the recommended COLD tire pressure. (See
“TPMS with Tire Infla-
tion Indicator” (P.5-7) about the
TPMS with Tire Inflation Indicator.)
Incorrect tire pressure, including
under inflation, may adversely affect
tire life and vehicle handling.
WARNING
. Improperly inflated tires can fail
suddenly and cause an accident.
. The Gross Vehicle Weight rating
(GVWR) is located on the F.M.V.S.
S./C.M.V.S.S. label. The vehicle
weight capacity is indicated on
the Tire and Loading Information
label. Do not load your vehicle
beyond this capacity. Overloading
your vehicle may result in reduced
tire life, unsafe operating condi-
tions due to premature tire failure,
or unfavorable handling character-
istics and could also lead to a
serious accident. Loading beyond
the specified capacity may also

result in failure of other vehicle
components.
. Before taking a long trip, or
whenever you heavily load your
vehicle, use a tire pressure gauge
to ensure that the tire pressures
are at the specified level.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information ”(US) or “Tire
Safety Information ”(Canada) in
the Warranty Information Booklet.

Tire wear and damage
WARNING
.Tires should be periodically in-
spected for wear, cracking, bul-
ging or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found,
the tire(s) should be replaced. .
The original tires have built-in
tread wear indicators. When wear
indicators are visible, the tire(s)
should be replaced.
. Tires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician, because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information ”(US) or “Tire
Safety Information ”(Canada) in
the Warranty Information Booklet.Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. (See
“Specifications” (P.9-8) for recommended
types and sizes of tires and wheels.)
WARNING
. The use of tires other than those
recommended or the mixed use of tires
of different brands, construction (bias,
bias-belted, radial or run-flat), or tread
patterns can adversely affect the ride,
braking, handling, ground clearance,
body-to-tire clearance, tire chain clear-
ance, speedometer calibration, head-
light aim and bumper height. Some of
these effects may lead to accidents and
could result in serious personal injury.
. For Two-Wheel Drive (2WD) models, if
your vehicle was originally equipped
with 4 tires that were the same size
and you are only replacing 2 of the 4
tires, install the new tires on the rear
axle. Placing new tires on the front axle
may cause loss of vehicle control in
some driving conditions and cause an
accident and personal injury.
. If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimension.
Wheels of a different off-set could cause
premature tire wear, degrade vehicle
handling characteristics and/or interfer-

TERMS
It is important to familiarize yourself
with the following terms before
loading your vehicle:
.Curb Weight (actual weight of yourvehicle) - vehicle weight includ-
ing: standard and optional equip-
ment, fluids, emergency tools,
and spare tire assembly. This weight
does not include passen-
gers and cargo.
.GVW (Gross Vehicle Weight) - curb weight plus the combined weight
of passengers and cargo.
.GVWR (Gross Vehicle Weight Rat-ing) - maximum total combined
weight of the unloaded vehicle,
passengers, luggage, hitch, trailer
tongue load and any other op-
tional equipment. This informa-
tion is located on the F.M.V.S.S./
C.M.V.S.S. label.
.GAWR (Gross Axle Weight Rating) -maximum weight (load) limit spe-
cified for the front or rear axle.
This information is located on the
F.M.V.S.S./C.M.V.S.S. label.
.GCWR (Gross Combined WeightRating) - The maximum total
weight rating of the vehicle, pas-
sengers, cargo, and trailer.
.Vehicle Capacity Weight, Loadlimit, Total load capacity - max-
imum total weight limit specified of the load (passengers and car-
go) for the vehicle. This is the
maximum combined weight of
occupants and cargo that can be
loaded into the vehicle. If the
vehicle is used to tow a trailer,
the trailer tongue weight must be
included as part of the cargo load.
This information is located on the
Tire and Loading Information la-
bel.
.Cargo capacity - permissible
weight of cargo, the weight of
total occupants weight subtracted
from the load limit.
VEHICLE LOADING INFORMATION

STI0365
VEHICLE LOAD CAPACITY
Do not exceed the load limit of your
vehicle shown as“The combined
weight of occupants and cargo” on
the Tire and Loading Information
label. Do not exceed the number of
occupants shown as “Seating Capa-
city” on the Tire and Loading In-
formation label.
To get “the combined weight of
occupants and cargo” , add the
weight of all occupants, then add the total luggage weight. Examples
are shown in the illustration.
Steps for determining correct load
limit
1.Locate the statement
“The com-
bined weight of occupants and
cargo should never exceed XXX kg
or XXX lbs” on your vehicle’ s
placard.
2.Determine the combined weight of
the driver and passengers that
will be riding in your vehicle.
3.Subtract the combined weight of
the driver and passengers from
XXX kg or XXX lbs.
4.The resulting figure equals the
available amount of cargo and
luggage load capacity. For exam-
ple, if the XXX amount equals
1400 lbs. and there will be five
150 lb. passengers in your vehi-
cle, the amount of available cargo
and luggage load capacity is 650
lbs. (1400 −750 (5 x 150) = 650
lbs or 640 −340 (5 x 70) = 300
kg.)
5.Determine the combined weight of
luggage and cargo being loaded
on the vehicle. That weight may
not safely exceed the available
cargo and luggage load capacity
calculated in Step 4.
6.If your vehicle will be towing a
trailer, load from your trailer will
be transferred to your vehicle.
Consult this manual to determine
how this reduces the available
Technical and consumer information9-17

9-18Technical and consumer information
cargo and luggage load capacity
of your vehicle.
Before driving a loaded vehicle,
confirm that you do not exceed the
Gross Vehicle Weight Rating (GVWR)
or the Gross Axle Weight Rating
(GAWR) for your vehicle. (See “Mea-
surement of weights” (P.9-18).)
Also check tires for proper inflation
pressures. See the Tire and Loading
Information label.
LOADING TIPS
.The GVW must not exceed GVWR or GAWR as specified on the F.M.V.
S.S./C.M.V.S.S. certification label.
.Do not load the front and rear axle
to the GAWR. Doing so will exceed
the GVWR.
WARNING
.Properly secure all cargo to help
prevent it from sliding or shifting.
Do not place cargo higher than the seatbacks. In a sudden stop or
collision, unsecured cargo could
cause personal injury.
.Do not load your vehicle any
heavier than the GVWR or the
maximum front and rear GAWRs.
If you do, parts of your vehicle can
break, tire damage could occur, or
it can change the way your vehicle
handles. This could result in loss
of control and cause personal
injury.
.Overloading could not only short-
en the life of your vehicle and the
tires, but also could lead to
hazardous vehicle handling and
long braking distance. This may
cause a premature tire malfunc-
tion, which could result in a
serious accident and personal in-
jury. Failures caused by overload-
ing are not covered by the
vehicle’s warranty.
MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight
shifts that could affect the balance of
your vehicle. When the vehicle is
loaded, drive to a scale and weigh
the front and the rear wheels sepa-
rately to determine axle loads. In-
dividual axle loads should not
exceed either of the gross axle
weight ratings (GAWR). The total of
the axle loads should not exceed the
gross vehicle weight rating (GVWR).
These ratings are given on the
vehicle certification label. If weight
ratings are exceeded, move or re-
move items to bring all weights
below the ratings.
