Tire and Loading Information
Label
A vehicle specic Tire and
Loading Information label is
attached to the vehicle’s center
pillar (B-pillar). With the driver’s
door open, you will nd the
label attached near the door
lock post. The Tire and Loading
Information label shows thenumber of occupant seating
positions (A), and the maximum
vehicle capacity weight (B) in
kilograms and pounds.
The Tire and Loading
Information label also shows
the tire size of the original
equipment tires (C) and the
recommended cold tire ination
pressures (D). For more
information on tires and ination
seeTires on page 9-39and
Inflation - Tire Pressure on
page 9-46.
There is also important loading
information on the Certication
label. It tells you the Gross
Vehicle Weight Rating (GVWR)
and the Gross Axle Weight
Rating (GAWR) for the front and
rear axle. See “Certication
Label” later in this section.Steps for Determining Correct
Load Limit
1.Locate the statement
“The combined weight
of occupants and cargo
should never exceed XXX kg
or XXX lbs” on your vehicle
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 gure equals
the available amount of
cargo and luggage load
capacity. For example,
if the “XXX” amount equals
1400 lbs and there will
be ve 150 lb passengers in
your vehicle, the amount
of available cargo and
luggage load capacity is
650 lbs (1400−750
(5 x 150) = 650 lbs).

Filling the Tank
{CAUTION
Fuel vapor burns violently and
a fuel re can cause bad
injuries. To help avoid injuries
to you and others, read and
follow all the instructions on
the pump island. Turn off your

Do not smoke if you are near
fuel or refueling your vehicle.
Do not use cellular phones.
Keep sparks, ames, and
smoking materials away from
fuel. Do not leave the fuel pump
unattended when refueling your
vehicle. This is against the law
in some places. Do not re-enter
the vehicle while pumping fuel.
Keep children away from the

you open the fuel cap too
quickly. If you spill fuel and
then something ignites it, you
could be badly burned. This
spray can happen if your tank
is nearly full, and is more likely
in hot weather. Open the fuel

fuse. If the motor overheats due
to heavy snow, etc., the wiper
will stop until the motor cools. If the
overload is caused by some
electrical problem, have it xed.
Power Windows and
Other Power Options
Circuit breakers in the fuse block
protect the power windows and
other power accessories. When the
current load is too heavy, the
circuit breaker opens and closes,

tire that has unseated from
the wheel. SeeRoadside Assistance
Program on page 12-6.
Do not remove any objects that
have penetrated the tire.
1. Place the tire sealant and
compressor kit on the ground and
unwrap the sealant/air hose (E)
from the side of the compressor.
2. Remove the air compressor
accessory plug (B) from the unit.
Do not plug the plug in yet.
3. Turn the tire valve stem cap
counterclockwise to remove.
4. Attach the sealant/air hose (E)
onto the tire valve stem. Turn
it clockwise until tight.5. Make sure the sealant and
compressor kit on/off switch (A) is

(e)Make sure the safety belt
reminder light and safety belt
assemblies are working properly.
Look for any other loose or
damaged safety belt system parts. If
you see anything that might keep
a safety belt system from doing
its job, have it repaired. Have any
torn or frayed safety belts replaced.
Also see Airbag System Check
on page 1-31.
(f)Lubricate all key lock cylinders,
door hinges and latches, hood
hinges and latches and trunk lid
hinges and latches. More frequent
lubrication may be required
when exposed to a corrosive
environment. Applying silicone
grease on weatherstrips with a clean
cloth will make them last longer,
seal better, and not stick or squeak.
(g)Visually inspect belt for fraying,
excessive cracks, or obvious
damage. Replace belt if necessary.(h)Change automatic transmission
fluid and filter if the vehicle is
mainly driven under one or more of
these conditions:
In heavy city traffic where the
outside temperature regularly
reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer
towing.
Uses such as found in taxi,
police, or delivery service.
(i)Drain, flush, and refill cooling
system. This service can be
complex; you should have your
dealer/retailer perform this service.
See Engine Coolant on page 9-13 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)If you drive regularly under dusty
conditions, inspect the filter at
each engine oil change.
(l)If you drive regularly under dusty
conditions, the filter may require
replacement more often.
(m)Drain, flush, and refill brake
hydraulic system at a regular service
interval (IorII) every two years.
This service can be complex;
you should have your dealer/retailer
perform this service. See Brakes
on page 9-24.
