CHANGING THE TIRES
If you get a flat tire while 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.
The use of tire sealants is not recommended and
may compromise the integrity of your tires. The use
of tire sealants may also affect your tire pressure
monitoring system (if equipped).
Temporary spare tire information
Your vehicle may have a temporary spare tire. The
temporary spare tire for your vehicle is labeled as
such. It is smaller than a regular tire and is designed
for emergency use only. Replace this tire with a
full-size tire as soon as possible.
Roadside Emergencies
165

Ifyou use the temporary spare tire
continuously or do not follow these
precautions, the tire could fail, causing you to lose
control of the vehicle, possibly injuring yourself or
others.
When driving with the temporary spare tiredo not:
•use more than one temporary spare tire at a time
•exceed 80 km/h (50 mph) or drive further than 3
200 km (2 000 miles) total under any
circumstances
•load the vehicle beyond maximum vehicle load
rating listed on the tire pressure label on the
inside of the glove compartment door
•tow a trailer
•use tire chains
•drive through an automatic car wash, because of
the vehicle’s reduced ground clearance
•try to repair the temporary spare tire or remove it
from its wheel
•use the wheel for any other type of vehicle
Use of a temporary spare tire at any one wheel
location can lead to impairment of the following:
•handling, stability and braking performance
•comfort and noise
•ground clearance and parking at curbs
•Winter driving capability
Tire change procedure
To prevent the vehicle from moving when
you change a tire, be sure the parking brake
is set, then block (in both directions) the wheel
that is diagonally opposite (other side and end of
the vehicle) to the tire being changed.
Roadside Emergencies
166

If the vehicle slips off the jack, you or
someone else could be seriously injured.
1. Park on a level
surface, activate hazard
flashers and set
parking brake.
2. Place gearshift lever
in P (Park) or R (manual transmission), turn engine
OFF, and block the diagonally opposite wheel.
3. Remove the spare
tire, jack and lug
wrench.
4. Remove the center
ornament (if equipped)
from the wheel. Loosen
each wheel lug nut
one-half turn
counterclockwise but
do not remove them
until the wheel is
raised off the ground.
Roadside Emergencies
167

5. Put the jack in the
jack notch next to the
tire you are changing.
Turn the jack handle
clockwise until the
wheel is completely off
the ground.
Never use the rear
differential as a
jacking point.
To lessen the
risk of personal
injury, do not put any
part of your body
under the vehicle
while changing a tire.
Do not start the
engine when your
vehicle is on the jack.
The jack is only
meant for changing
the tire.
6. Remove the lug nuts with the lug wrench.
7. Replace the flat tire with the spare tire, making
sure the valve stem is facing outward. Reinstall lug
nuts until the wheel is snug against the hub. Do not
fully tighten the lug nuts until the wheel has been
lowered.
If you are using the temporary tire, the lug nut
washers will not appear to be flush with the rim.
This is normal only when using the temporary spare
tire.
8. Lower the wheel by turning the jack handle
counterclockwise.
