FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Note:Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.

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.
Temporary spare tire information
Your vehicle may have a temporary or full-size 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.
If you 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.
Roadside Emergencies
166

When driving with the temporary spare tiredo not:
²exceed 80 km/h (50 mph) under any circumstances
²load the vehicle beyond maximum vehicle load rating listed on the
Safety Compliance Label
²tow a trailer
²use tire chains
²drive through an automatic car wash, because of the vehicle's reduced
ground clearance
²try to repair the temporary spare tire or remove it from its wheel
²use the wheel for any other type of vehicle
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.
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),
turn engine OFF and block the
diagonally opposite wheel.
