Maintenance and care
206

Do not replace your tires with ªhigh performanceº tires or larger
size tires.
Failure to follow these precautions may adversely affect the
handling of the vehicle and make it easier for the driver to lose
control and roll over.
Tires that are larger or smaller than your vehicle's original tires may also
affect the accuracy of your speedometer.
SNOW TIRES AND CHAINS
Driving too fast for conditions creates the possibility of loss of
vehicle control. Driving at very high speeds for extended periods
of time may result in damage to vehicle components.
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
The tires on your vehicle have all weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains. If you need to use snow tires and chains, it is
recommended that steel wheels are used of the same size and
specifications as those originally installed.
Follow these guidelines when using snow tires and chains:
²Do not use tire chains on aluminum wheels. Chains may chip the
wheels.
²Use only SAE Class S chains.
²Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
²Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
²If possible, avoid fully loading your vehicle.
²Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.

5. Remove the bulb retaining ring by
rotating it counterclockwise (when
viewed from the rear) to free it
from the bulb socket, and slide the
ring off the plastic base. Keep the
ring to retain the new bulb.
6. Without turning, remove the old
bulb by gently pulling it straight
back out of the lamp assembly.
To install the new bulb:
Handle a halogen headlamp bulb carefully and keep out of
children's reach. Grasp the bulb only by its plastic base and do
not touch the glass. The oil from your hand could cause the bulb to
break the next time the headlamps are operated.
1. With the flat side of the bulb's plastic base facing upward, insert the
glass end of the bulb into the lamp assembly. You may need to turn the
bulb left or right to align the grooves in the plastic base with the tabs in
the lamp assembly. When the grooves are aligned, push the bulb into the
lamp assembly until the plastic base contacts the rear of the lamp
assembly.
2. Install the bulb retaining ring over the plastic base until it contacts the
rear of the socket by rotating clockwise until you feel a ªstop.º
3. Install the electrical connector into the plastic base until it snaps,
locking it into position.
4. Install the headlamp on vehicle, push rearward and secure with two
retainer pins.
5. Install the cover with two screws (if equipped).
6. Turn the headlamps on and make sure they work properly. If the
headlamp was correctly aligned before you changed the bulb, you should
not need to align it again.
