norm due to variations in driving
habits, service practices and
differences in road
characteristics and climate.
Traction
The traction grades, from
highest to lowest, are AA, A, B,
and C. Those grades represent
the tire's ability to stop on wet
pavement as measured under
controlled conditions on
specified government test
surfaces of asphalt and
concrete. A tire marked C may
have poor traction performance.
Warning: The traction grade
assigned to this tire is based on
straight-ahead braking traction
tests, and does not include
acceleration, cornering,
hydroplaning, or peak traction
characteristics.
Temperature
The temperature grades are A
(the highest), B, and C,
representing the tire's resistanceto the generation of heat and its
ability to dissipate heat when
tested under controlled
conditions on a specified indoor
laboratory test wheel. Sustained
high temperature can cause the
material of the tire to degenerate
and reduce tire life, and
excessive temperature can lead
to sudden tire failure. The grade
C corresponds to a level of
performance which all
passenger car tires must meet
under the Federal Motor Safety
Standard No. 109. Grades B and
A represent higher levels of
performance on the laboratory
test wheel than the minimum
required by law. Warning: The
temperature grade for this tire is
established for a tire that is
properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
buildup and possible tire failure.Wheel Alignment and Tire
Balance
The tires and wheels were aligned
and balanced at the factory to
provide the longest tire life and best
overall performance. Adjustments to
wheel alignment and tire balancing
are not necessary on a regular
basis. Consider an alignment check
if there is unusual tire wear or the
vehicle is significantly pulling to one
side or the other. Some slight pull to
the left or right, depending on the
crown of the road and/or other road
surface variations such as troughs
or ruts, is normal. If the vehicle is
vibrating when driving on a smooth
road, the tires and wheels may need
to be rebalanced. See your dealer
for proper diagnosis.
Wheel Replacement
Replace any wheel that is bent,
cracked, or badly rusted or
corroded. If wheel nuts keep coming
loose, the wheel, wheel bolts, and
wheel nuts should be replaced.
If the wheel leaks air, replace it.

only. Cables should not be
installed on the spare tire or on
the optional 19-inch tire.
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires
are maintained properly. SeeTires
0 231. If air goes out of a tire, it is
much more likely to leak out slowly.
But if there ever is a blowout, here
are a few tips about what to expect
and what to do:
If a front tire fails, the flat tire
creates a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the
steering wheel firmly. Steer to
maintain lane position, and then
gently brake to a stop, well off the
road, if possible.
A rear blowout, particularly on a
curve, acts much like a skid and
may require the same correction as
used in a skid. Stop pressing the
accelerator pedal and steer to straighten the vehicle. It may be
very bumpy and noisy. Gently brake
to a stop, well off the road,
if possible.
{Warning
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
underinflated or flat may cause a
blowout and a serious crash.
Never attempt to re-inflate a tire
that has been driven on while
severely underinflated or flat.
Have your dealer or an authorized
tire service center repair or
replace the flat tire as soon as
possible.
{Warning
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the
appropriate safety equipment and

training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could
be badly injured or killed if the
vehicle slips off the jack. If a jack
is provided with the vehicle, only
use it for changing a flat tire.
If a tire goes flat, avoid further tire
and wheel damage by driving slowly
to a level place, well off the road,
if possible. Turn on the hazard
warning flashers. See Hazard
Warning Flashers 0132.
{Warning
Changing a tire can be
dangerous. The vehicle can slip
off the jack and roll over or fall
causing injury or death. Find a
level place to change the tire. To
help prevent the vehicle from
moving:

2. The vehicles should be closeenough for the jumper cables
to reach, but the vehicles
should not be touching.
Touching could cause
grounding and possible
electrical system damage.
Put both vehicles in P (Park)
and set the parking brake
firmly.
3. Unplug accessories plugged into the cigarette lighter or the
accessory power outlet. Turn
off the radio and all lamps that
are not needed. Turn off the
ignition on both vehicles.
4. Locate the positive (+) and negative (−) terminals on both
vehicles. Some vehicles have
remote jump starting terminals.
{Warning
An electric fan can start up even
when the engine is not running
and can injure you. Keep hands,
clothing, and tools away from any
underhood electric fan. 5. The remote positive (+)
terminal (1) is located on the
underhood fuse block, on the
driver side. Lift the red cap to
uncover the terminal.
The remote negative (−)
terminal (2) is a stud behind
the metal tab stamped with
GND (−) near the driver side
strut tower.
6. The jumper cables should be in good working condition with no
loose or missing insulation.
The vehicles could be
damaged if they are not.
7. Connect the red positive (+) cable to the positive (+)
terminal on the vehicle with the
dead battery. Use a remote
positive (+) terminal if the
vehicle has one.
8. Do not let the other end touch metal. Connect it to the
positive (+) terminal of the
good battery. Use a remote
positive (+) terminal if the
vehicle has one. 9. Connect the black negative (−)
cable to the negative (−)
terminal of the good battery.
Use a remote negative (−)
terminal if the vehicle has one.
Do not let the other end touch
anything until the next step.
The other end of the negative
(−) cable does not go to the
dead battery. It goes to a
heavy, unpainted metal engine
part or to a remote negative (−)
terminal on the vehicle with the
dead battery.
10. Connect the other end of the negative (−) cable away from
the dead battery, but not near
engine parts that move.
11. Start the vehicle with the good battery and run the engine.
12. Press the unlock symbol on the Remote Keyless Entry (RKE)
transmitter to disarm the
security system, if equipped.
13. Try to start the vehicle that had the dead battery. If it will not
start after a few tries, it needs
service.

Caution
If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.
Always connect and remove the
jumper cables in the correct order,
making sure that the cables do
not touch each other or other
metal.
Jumper Cable Removal
Reverse the sequence exactly when
removing the jumper cables.
After starting the disabled vehicle
and removing the jumper cables,
allow it to idle for several minutes.
Towing the Vehicle
Caution
Incorrectly towing a disabled
vehicle may cause damage. The
damage would not be covered by
the vehicle warranty.
Do not lash or hook to
suspension components. Use the
proper straps around the tires to
secure the vehicle.
Have the vehicle towed on a flatbed
car carrier. A wheel lift tow truck
could damage the vehicle.
Consult your dealer or a
professional towing service if the
disabled vehicle must be towed.
Recreational Vehicle
Towing
Recreational vehicle towing means
towing the vehicle behind another
vehicle –such as behind a motor
home. The two most common types
of recreational vehicle towing are known as dinghy towing and dolly
towing. Dinghy towing is towing the
vehicle with all four wheels on the
ground. Dolly towing is towing the
vehicle with two wheels on the
ground and two wheels up on a
device known as a dolly.
Here are some important things to
consider before recreational vehicle
towing:
.
The towing capacity of the
towing vehicle. Be sure to read
the tow vehicle manufacturer's
recommendations.
. How far the vehicle will be
towed. Some vehicles have
restrictions on how far and how
long they can tow.
. The proper towing equipment.
See your dealer or trailering
professional for additional advice
and equipment
recommendations.
. If the vehicle is ready to be
towed. Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed.
