2. Put a vehicle with an automatictransmission in Park (P), a manual
transmission in Reverse (R) or 1,
and turn off the engine.
3. Turn on the hazard warning flasher.
4. Have passengers get out of the vehicle and away from the vehicle
and traffic.
5. Remove any luggage, the jack, tools, and spare tire (page 7-3).
6. Block the wheel diagonally opposite the flat tire. When
blocking a wheel, place a tire block
both in front and behind the tire.
NOTE
When blocking a tire, use rocks or
wood blocks of sufficient size if
possible to hold the tire in place.
▼Removing a Flat Tire
WARNING
When jacking-up a vehicle, always
shift the shift lever to 1st or R position
(manual transmission vehicle) or shift
the selector lever to P position
(automatic transmission vehicle),
apply the parking brake, and place
wheel blocks in the position
diagonally opposed to the jack:
Changing a flat tire without using
wheel blocks is dangerous because the
vehicle may move and fall off the jack
even with the shift lever in 1st or R
position, or the selector lever is in P
position, which could result in an
accident.
1. If your vehicle is equipped with a
wheel cover, pry off the wheel
cover with the beveled end of the
jack lever.

NOTE
Force the end of the jack lever
firmly between wheel and cover, or
removal will be difficult.

Tire Labeling
▼Tire Labeling
Federal law requires tire manufacturers
to place standardized information on
the sidewall of all tires. This
information identifies and describes
the fundamental characteristics of the
tire and also provides a tire
identification
number for safety
standard certification and in case of a
recall.

Tread Wear, Traction and Temperature
Grades
Trea d wea r : The tread wear grade is a
comparative rating based on the wear
rate of the tire when tested under
controlled conditions on a specified
government test course. For example,
a tire graded 150 would wear one and
one-half (1 1/2) times as well on the
government course as a tire graded
100.
Tra c t i o n : The traction grades, from
highest to lowest are AA, A, B, and C.
The grades represent the tire's ability
to stop on wet pavement as measured
under controlled conditions on
specified government te
st surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
Temperature: The temperature grades
are A (the highest), B and C,
representing the tire's resistance to the
generation of heat and its ability to
dissipate heat when tested under
controlled conditions on a specified
indoor laboratory test wheel.
Snow Tires
In some heavy snow areas, local
governments may require true snow
tires, those with very deeply cut tread.
These tires should only be used in pairs
or placed on all four wheels. Make
sure you purchase snow tires that are
the same size and construction type as
the other tires on your vehicle.
SAFETY WARNING
The following safety warning appears
on the tire's sidewall.

Location of the Tire Label(Placard)
▼Location of the Tire Label (Placard)
You will find the tire label containing
tire
inflation pressure by tire size and
other important information on the
driver's side B-pillar or on the edge of
the driver's door frame.

SAMPLE
▼ Recommended Tire Inflation
Pressure
On the tire label you will find the
recommended tire
inflation pressure in
both kPa and psi for the tires installed
as original equipment on the vehicle. It
is very important that the inflation
pressure of the tires on your vehicle is
maintained at the recommended
pressure. You should check the tire
pressure regularly to insure that the
proper inflation pressure is maintained.
Refer to Tires on page 9-8.
NOTE
Tire pressures listed on the vehicle
placard or tire information label
indicate the recommended cold tire
inflation pressure, measured when the
tires are cold, after the vehicle has
been parked for at least 3 hours. As
you drive, the temperature in the tire
warms up, increasing the tire pressure.
WARNING
Always check the tire inflation
pressures on a regular basis according
to the recommended tire inflation
pressure on the tire label and in
conjunction with the information in
this owner's manual:
Driving your vehicle with
under-inflated tires is dangerous.
Under-inflation is the most common
cause of failures in any kind of tire and
may result in severe cracking , tread
separation or “blowout”, with
unexpected loss of vehicle control and
increased risk of injury. Under-inflation
increases sidewall flexing and rolling
resistance, resulting in heat buildup
and internal damage to the tire. It
results in unnecessary tire stress,
irregular wear, loss of control and
accidents. A tire can lose up to half of
its air pressure and not appear to be
flat!
It is impossible to determine whether
or not tires are properly inflated just by
looking at them.
▼ Checking Tire Pressure
1. When you check the air pressure,
make sure the tires are cold
―meaning they are not hot from
driving even a mile.
2. Remove the cap from the valve on
one tire.
3. Firmly press a tire gauge onto the valve.
4. Add air to achieve recommended air pressure.
5. If you overfill the tire, release air by pushing on the metal stem in the
center of the valve. Then recheck
the pressure with your tire gauge.
6. Replace the valve cap.
7. Repeat with each tire, including the spare.

NOTE
Some spare tires require higher
inflation pressure.
8. Visually inspect the tires to make sure there are no nails or other
objects embedded that could poke
a hole in the tire and cause an air
leak.
9. Check the sidewalls to make sure there are no gouges, cuts, bulges,
cracks or other irregularities.
▼Glossary of Terms
Tire Placard:
A label indicating the OE
tire sizes, recommended inflation
pressure, and the maximum weight the
vehicle can carry.

amount of air in a tire.
kPa: Kilopascal, the metric unit for air
pressure.
psi: Pounds per square inch, the
English unit for air pressure.
B-pillar: The structural member at the
side of the vehicle behind the front
door.
Original Equipment (OE): Describes
components originally equipped on

Overloading makes a vehicle harder to
drive and control. It also increases the
distance required for stopping. In cases
of serious overloading, brakes can fail
completely, particularly on steep
grades. The load a tire will carry safely
is a combination of the size of the tire,
its load range, and corresponding
inflation pressure.
Never overload the vehicle and always
observe the vehicle's weight ratings
from the vehicle's Safety Certification
and Tire and Load Information labels.Base Curb Weight is the weight of the
vehicle including a full tank of fuel
and all standard equipment. It does
not include passengers, cargo, or
optional equipment.

Vehicle Curb Weight is the weight of
your new vehicle when you picked it
up from your dealer plus any
aftermarket equipment.

PAY LOA D
Pay l o a d is the combination weight of
cargo and passengers that the vehicle
is designed to carry. The maximum
payload for your vehicle can be found
on the Tire and Load Information label
on the driver's door frame or door
pillar. Look for “THE COMBINATION
WEIGHT OF OCCUPANTS AND
CARGO SHOULD NEVER EXCEED XXX
kg or XXX lbs” for your maximum
payload. The payload listed on the tire
label is the maximum payload for the
vehicle as built by the assembly plant.
If any aftermarket or dealer installed
equipment has been installed on the
vehicle, the weight of the equipment
must be subtracted from the payload
listed on the tire label in order to be
accurate.
