Spare Tire
Compact Spare Tire
Your vehicle may have a compact spare tire.
Although the compact spare tire was fully inated
when the vehicle was new, it can lose air after
a time. Check the ination pressure regularly. It
should be 60 psi (420 kPa).
438

After installing the compact spare on the vehicle,
stop as soon as possible and make sure the
spare tire is correctly inated. The compact spare
is made to perform well at speeds up to 65 mph
(105 km/h) for distances up to 3,000 miles
(5 000 km), so you can nish your trip and have
the full-size tire repaired or replaced at your
convenience. Of course, it is best to replace the
spare with a full-size tire as soon as possible. The
spare tire will last longer and be in good shape
in case it is needed again.
Notice:When the compact spare is installed,
do not take your vehicle through an automatic
car wash with guide rails. The compact
spare can get caught on the rails. That can
damage the tire and wheel, and maybe
other parts of your vehicle.
Do not use the compact spare on other vehicles.
And do not mix the compact spare tire or
wheel with other wheels or tires. They will not t.
Keep the spare tire and its wheel together.
Notice:Tire chains will not t your compact
spare. Using them can damage your vehicle
and can damage the chains too. Do not use tire
chains on your compact spare.Spare Tire
Your vehicle may have a spare tire, which, when
new, was fully inated. A spare tire may lose
air over time, so check its ination pressure
regularly. SeeInation - Tire Pressure on
page 411andLoading Your Vehicle on page 333
for information regarding proper tire ination
and loading your vehicle. For instructions on how
to remove, install or store a spare tire, see
Removing the Flat Tire and Installing the Spare
Tire on page 431.
After installing the spare tire on your vehicle, you
should stop as soon as possible and make
sure the spare is correctly inated. Have the
damaged or at road tire repaired or replaced as
soon as you can and installed back onto your
vehicle. This way, a spare tire will be available in
case you need it again.
Your vehicle may have a different size spare tire
than the road tire originally installed on your
vehicle. This spare tire was developed for use on
your vehicle, so it is all right to drive on it.
If your vehicle has a spare tire that does not
match your vehicle’s original road tires and wheels
in size and type, do not include the spare in the
tire rotation.

further details.
Notice:It is important to check the engine oil
regularly and keep it at the proper level.
Failure to keep the engine oil at the proper
level can cause damage to the engine not
covered by your warranty.
Engine Coolant Level Check
Check the engine coolant level and add
DEX-COOL®coolant mixture if necessary. See
Engine Coolant on page 374for further details.
Windshield Washer Fluid Level Check
Check the windshield washer uid level in
the windshield washer uid reservoir and add the
proper uid if necessary.
At Least Once a Month
Tire Ination Check
Inspect your vehicle’s tires and make sure they
are inated to the correct pressures. Do not forget
to check the spare tire. SeeInation - Tire
Pressure on page 411. Check to make sure the
spare tire is stored securely. SeeChanging a Flat
Tire on page 428.
Tire Wear Inspection
Tire rotation may be required for high mileage
highway drivers prior to the Engine Oil Life System
service notication. Check the tires for wear
and, if necessary, rotate the tires. SeeTire
Inspection and Rotation on page 418.
