WARNING
Tire Under-Inflation:
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.
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.
qChecking 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 or other
irregularities.

NOTE
Warm tires normally exceed recommended pressures. Don't release air from warm tires
to adjust the pressure.
Under-inflation can cause serious failures and accidents.
Over-inflation can produce a harsh ride and the greater possibility of damage from road
hazards.
qGlossary of Terms
Tire Placard:A label indicating the OE tire sizes, recommended inflation pressure, and

information about the tire brand and manufacturing plant, tire size, and date of
manufacture.
Inflation Pressure:A measure of the amount of air in a tire.
kPa:Kilopascal, the metric 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 the vehicle.
Vehicle Load Limit:The maximum value of the combined weight of occupants and cargo.
Bead Area of the Tire:Area of the tire next to the rim.
Sidewall Area of the Tire:Area between the bead area and the tread.
Tread Area of the Tire:Area on the perimeter of the tire that contacts the road when it's
mounted on the vehicle.
Seating capacitymeans the total allowable number of vehicle occupants. Seating capacity
is described on the tire label.
Production options weightis the combined weight of installed regular production options
weighing over 2.3 kilograms in excess of the standard items which they replace, and not

Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to wear abnormally. Here are
some important maintenance points:
qTire Inflation Pressure
Inspect all tire pressure monthly (including the spare) when the tires are cold. Maintain
recommended pressures for the best ride, top handling, and minimum tire wear. Use the
pressures specified on the vehicle tire information placard or tire label for optimum service.
qTire Rotation
To equalize tread wear, rotate the tires every 12,000 km (7,500 miles) or sooner if irregular
wear develops. During rotation, inspect them for correct balance.
Forward
Inspect the tires for uneven wear and damage. Abnormal wear is usually caused by one or a
combination of the following:
lIncorrect tire pressure
lImproper wheel alignment
lOut-of-balance wheel
lSevere braking
After rotation, inflate all tire pressures to specification (page 10-6) and inspect the lug nuts
for tightness.

CAUTION
Rotate unidirectional tires and radial tires that have an asymmetrical tread pattern or
studs only from front to rear, not from side to side. Tire performance will be weakened if
rotated from side to side.
(With limited-slip differential)
Don't use the following:
lTires not of the designated size
lTires of different sizes or types at the same time
lTires not sufficiently inflated
If these instructions aren't followed, the rotation of the left and right wheels will be
different and will thus apply a constant load on the limited-slip differential.
This will cause a malfunction.
qReplacing a Tire
WARNING
Worn Tires:
Driving with worn tires is dangerous. Reduced braking, steering, and traction could
result in an accident. Always use tires that are in good condition.
If a tire wears evenly, a wear indicator will appear as a solid band across the tread. Replace
the tire when this happens.

Worn tread
You should replace it before the band is across the entire tread.

qSafety Practices
The way you drive has a great deal to do with your tire mileage and safety. So cultivate
good driving habits for your own benefit.
lObserve posted speed limits
lAvoid fast starts, stops and turns
lAvoid potholes and objects on the road
lDo no run over curbs or hit the tire against the curb when parking
CAUTION
If you feel a sudden vibration or ride disturbance while driving or you suspect your tire
or vehicle has been damaged, immediately reduce your speed. Drive with caution until
you can safely pull off the road. Stop and inspect the tire for damage. If the tire is under-
inflated or damaged, deflate it, remove the tire and rim and replace it with your spare
tire. If you cannot detect a cause, have the vehicle towed to the nearest vehicle or tire
dealer to have the vehicle inspected.

Vehicle Loading
This section will guide you in the proper loading of your vehicle and/or trailer, to keep
your loaded vehicle weight within its design rating capability, with or without a trailer.
Properly loading your vehicle will provide maximum return of vehicle design performance.
Before loading your vehicle, familiarize yourself with the following terms for determining
your vehicle's weight ratings, with or without a trailer, from the vehicle's Safety
Certification Label and Tire and Load Information Label:
WARNING
Overloaded Vehicle:
Overloading a vehicle is dangerous. The results of overloading can have serious
consequences in terms of passenger safety. Too much weight on a vehicle's suspension
system can cause spring or shock absorber failure, brake failure, handling or steering
problems, irregular tire wear, tire failure or other damage.
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 Weightis the weight of your new vehicle when you picked it up from your
dealer plus any aftermarket equipment.
PAYLOAD
Payloadis the combined 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 COMBINED
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.

SAMPLE
CARGO
Cargo Weightincludes all weight added to the Base Curb Weight, including cargo and
optional equipment. When towing, trailer tongue load or king pin weight is also part of
cargo weight.
The cargo weight limit decreases depending on the number of vehicle occupants. The cargo
weight limit can be calculated by subtracting the total weight of the vehicle occupants from
the“combined weight of occupants and cargo should never exceed”value on the tire label.
