Changing a Flat Tire
NOTE
If the following occurs while driving, it
could indicate a flat tire.
Steering becomes difficult.
The vehicle begins to vibrate
excessively.
The vehicle pulls in one direction.
If you have a flat tire, drive slowly to a
level spot that is well off the road and out
of the way of traffic to change the tire.
Stopping in traffic or on the shoulder of a
busy road is dangerous.
WA R N I N G
Be sure to follow the directions for
changing a tire:
Changing a tire is dangerous if not done
properly. The vehicle can slip off the jack
and seriously injure someone.
No person should place any portion of their
body under a vehicle that is supported by a
jack.
Never allow anyone inside a vehicle
supported by a jack:
Allowing someone to remain in a vehicle
supported by a jack is dangerous. The
occupant could cause the vehicle to fall
resulting in serious injury.
NOTE
Make sure the jack is well lubricated
before using it.

unnecessary electrical loads in both
vehicles.
4. Connect the jumper cables in the exact
sequence as in the illustration.
Connect one end of a cable to the
positive terminal on the discharged
battery (1).
Attach the other e nd to the positive
terminal on the booster battery (2).
Connect one end of the other cable
to the negative terminal of the
booster battery (3).
Connect the other end to the ground
point indicated in the illustration
away from the discharged battery
(4).
5. Start the engine of the booster vehicle
and run it a few minutes. Then start the
engine of the other vehicle.

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.

▼ Replacing a Tire
WA R N I N G
Always use tires that are in good condition:
Driving with worn tires is dangerous. Reduced braking, steering, and traction could result in
an accident.
If a tire wears evenly, a wear i
ndicator will appear as a solid band across the tread.
Replace the tire when this happens.
New tread Tread wear indicator
Worn tread
You should replace the tire before the band crosses the entire tread.
(With tire pressure monitoring system)
After adjusting the tire pressur e, initialization of the tire pressure monitoring system is
necessary to make the system operate normally.
Refer to Tire Pressure Monitorin g System Initialization on page 4-148.
NOTE
Tires degrade over time, even when they are not being used on the road. It is recommended
that tires generally be replaced when they are 6 years or older. Heat caused by hot climates
or frequent high load ing conditions can accelerate the aging proc ess. You should replace
the spare tire when you replace the other road tires due to the aging of the spare tire. The
period in which the tire was manufactured (both week and year) is indicated by a 4-digit
number.
Refer to Tire Labeling on page 8-25.

WA R N I N G
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 desi gn rating capability. Properly lo ading your vehicle will provide
maximum return of vehicle design performance. Before loading yo ur vehicle, familiarize
yourself with the following terms for determining your vehicle' s weight ratings, from the
vehicle's Safety Certification La bel and Tire and Load Information Label:
WA R N I N G
Overloaded Vehicle:
Overloading a vehicle is danger ous. 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 th e vehicle's weight ratings from the vehicle's
Safety Certification and Tire and Load Information labels.
