D
“D” is the tire construction symbol. D
indicates “diagonal ply construction”.
16
“16” is the wheel rim diameter in
inches.
90
“90” is the Load Index. This two-or
three-digit number indicates how
much weight each tire can support.
M
“M” is the speed rating. The speed
rating denotes the maximum speed for
which the use of the tire is rated.
Letter Rating Speed Rating
M 81 mph
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 9-7.
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 ma ximum weight the
vehicle can carry.
Tire Identification Number (TIN): A
number on the sidewall of each tire

WARNING
Do not tow a trailer with this vehicle:
Towing a trailer with this vehicle is
dangerous because it has not been
designed to tow a trailer and doing so
will
affect the drive system which could
result in vehicle damage.
This section will guide you in the
proper loading of your vehicle, to keep
your loaded vehicle weight within its
design rating capability. 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, 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 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
