INSPECTING THE TIRE FOR
WEAR

E142546

When the tread is worn down to
one sixteenth of an inch (2 mm),
tires must be replaced to help
prevent your vehicle from skidding
and hydroplaning. Built-in
treadwear indicators, or wear bars,
which look like narrow strips of
smooth rubber across the tread
will appear on the tire when the
tread is worn down to one
sixteenth of an inch (2 mm).

When the tire tread wears down
to the same height as these wear
bars, the tire is worn out and must
be replaced.

The tires should also be balanced
periodically. An unbalanced tire
and wheel assembly may result in
irregular tire wear.

Periodically inspect the tire treads
for uneven or excessive wear and
remove objects such as stones,
nails or glass that may be wedged
in the tread grooves.

INSPECTING THE TIRE FOR
DAMAGE

Inspect the tire sidewalls for
cracking, cuts, bruises and other
signs of damage or excessive
wear. If internal damage to the tire
is suspected, have the tire
dismounted and inspected in case
it needs to be repaired or replaced.
For your safety, tires that are
damaged or show signs of
excessive wear should not be used
because they are more likely to
blow out or fail.

Periodically inspect the tire treads
and sidewalls for damage, such
as bulges in the tread or sidewalls,
cracks in the tread groove and
separation in the tread or sidewall.

If damage is observed or
suspected, have the tire inspected
by a tire professional.

Safety Practices

WARNING:

If your vehicle

is stuck in snow, mud or sand, do
not rapidly spin the tires;
spinning the tires can tear the
tire and cause an explosion. A
tire can explode in as little as
three to five seconds.

WARNING:

Do not spin the

wheels at over 34 mph
(55 km/h). The tires may fail and
injure a passenger or bystander.

Tire Care

Highway Hazards

No matter how carefully you drive,
there is always the possibility that
you could eventually have a flat
tire on the highway. Drive slowly
to the closest safe area out of
traffic. This could further damage
the flat tire, but your safety is
more important.

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
tires for damage. If a tire is
under-inflated or damaged,
deflate it, remove the wheel and
replace it with your spare tire and

wheel. If you cannot detect a
cause, have the vehicle towed to
the nearest repair facility or tire
dealer to have the vehicle
inspected.

Tire and Wheel Alignment

A bad jolt from hitting a curb or
pothole can cause the front end
of your vehicle to become
misaligned or cause damage to
your tires. If your vehicle seems to
pull to one side when you are
driving, the wheels could be out of
alignment. Have an authorized
dealer check the wheel alignment
periodically.

Wheel misalignment in the front
or the rear can cause uneven and
rapid treadwear of your tires and
should be corrected by an
authorized dealer.

INSPECTING THE WHEEL
VALVE STEMS

Check the valve stems for holes,
cracks, or cuts that could permit
air leakage.

TIRE ROTATION

WARNING:

If the tire label

shows different tire pressures for
the front and rear tires and the
vehicle has a tire pressure
monitoring system, then you
need to update the settings for
the system sensors. Always
perform the system reset
procedure after tire rotation. If
you do not reset the system, it
may not provide a low tire
pressure warning when
necessary.

Note:

If your tires show uneven

wear ask an authorized dealer to
check for and correct any wheel
misalignment, tire imbalance or
mechanical problem involved
before tire rotation.

Note:

After having your tires

rotated, inflation pressure must be
checked and adjusted to the
vehicle requirements.

389

Tire Care

Rotating your tires at the
recommended interval, as
indicated in the scheduled
maintenance chapter, will help
your tires wear more evenly,
providing better tire performance
and longer tire life.

For the best tire life, a five tire
rotation is recommended that
includes the matching spare tire
mounted on the back of the
vehicle. This rotation requires a
forced re-learning of your tire
pressure monitor system sensors
by your vehicle, and should be
performed by an authorized dealer
or a service center to ensure the
tire pressure monitor system will
provide proper warning at all
times. When performing the tire

rotation yourself, a four tire
rotation is recommended, without
using the spare tire in the rotation,
so that no tire pressure monitor
system sensor re-learn is required.
If a five tire rotation is performed
without a tire pressure monitor
system sensor re-learn, the
system may not provide a low tire
pressure warning when necessary.

Keep in mind that a spare tire that
is not used in the tire rotation
should only be used temporarily
in the event of a flat tire, not as a
permanent replacement. The
spare tire should always be
replaced if it exceeds 6 years of
age, regardless of whether it is
part of the tire rotation.

four-wheel drive vehicles with four
tire rotation, front tires at left of

Sometimes irregular tire wear can
be corrected by rotating the tires.

Tire Care

WHAT IS THE TIRE PRESSURE
MONITORING SYSTEM

The tire pressure monitoring
system measures the vehicle's
tire pressures. A warning lamp

illuminates if one or more tires are
significantly underinflated or if there is a
system malfunction.

TIRE PRESSURE MONITORING
SYSTEM OVERVIEW

WARNING:

If the tire pressure

monitor sensor becomes damaged it
may not function.

WARNING:

Under-inflation is the

most common cause of tire failures and
may result in severe tire 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 also may result in
unnecessary tire stress, irregular wear,
loss of vehicle control and accidents. A
tire can lose up to half of its air pressure
and not appear to be flat!

WARNING:

To determine the

required pressure(s) for your vehicle, see
the Safety Compliance Certification
Label (on the door hinge pillar,
door-latch post or the door edge that
meets the door-latch post, next to the
driver seat) or the Tire Label on the
B-Pillar or the edge of the driver door.

Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure
recommended by the vehicle manufacturer
on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of
a different size than the size indicated on
the vehicle placard or tire inflation pressure
label, you should determine the proper tire
inflation pressure for those tires).

As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on a
significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the
vehicle’s handling and stopping ability.

Please note that the TPMS is not a
substitute for proper tire maintenance, and
it is the driver’s responsibility to maintain
correct tire pressure, even if under-inflation
has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.

Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence
will continue upon subsequent vehicle
start-ups as long as the malfunction exists.

391

Tire Pressure Monitoring System

When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.

TIRE PRESSURE MONITORING
SYSTEM PRECAUTIONS

WARNING:

The tire pressure

monitoring system is not a substitute for
manually checking tire pressures. You
should periodically check tire pressures
using a pressure gauge. Failure to
correctly maintain tire pressures could
increase the risk of tire failure, loss of
control, vehicle rollover and personal
injury.

WARNING:

Do not use the tire

pressure displayed in the information
display as a tire pressure gauge. Failure
to follow this instruction could result in
personal injury or death.

Note:

The use of tire sealants can damage

the tire pressure monitoring system.

TIRE PRESSURE MONITORING
SYSTEM LIMITATIONS

When the outside temperature drops
significantly, the tire pressure could
decrease and activate the low tire pressure
warning lamp.

The warning lamp could also illuminate
when you use a spare wheel, or tire sealant
from the inflator kit.

Note:

Regularly checking the vehicle tire

pressures can reduce the possibility for the
warning lamp to illuminate due to outside
air temperature changes.

Note:

After you inflate the tires to the

recommended pressure it could take up to
two minutes of driving over 20 mph
(32 km/h) for the warning indicator to turn
off.

CHANGING A FLAT TIRE

Note:

You should only use tire sealants in

roadside emergencies as they may cause
damage to the tire pressure monitoring
system sensor.

Note:

The tire pressure monitoring system

indicator light illuminates when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.

If you get a flat tire when driving, do not
apply the brake heavily. Instead, gradually
decrease your speed, hold the steering
wheel firmly, and slowly move to a safe
place on the side of the road.

Have your flat serviced by an authorized
dealer in order to prevent damage to the
tire pressure monitoring system sensors.
Replace the spare tire with a road tire as
soon as possible. During repairing or
replacing of the flat tire, have the
authorized dealer inspect the tire pressure
monitoring system sensor for damage.
