WARNING: Handling Halogen Bulbs: When a halogen bulb
breaks, it is dangerous. These bulbs contain pressurized gas. If
one is broken, it will explode and serious injuries could be
caused by the flying glass. If the glass portion of the bulb is
touched with bare hands, body oil could cause the bulb to
overheat and explode when lit. Never touch the glass portion of
the bulb with your bare hands and always wear eye protection
when handling or working around halogen bulbs.

WARNING: Children and Halogen Bulbs: Playing with a halogen
bulb is dangerous. Serious injuries could be caused by dropping
a halogen bulb or breaking in some other way. Always keep
halogen bulbs out of the reach of children.
To remove the headlamp bulb: 1. Make sure headlamp switch is in OFF position, then open the hood.
2. Reach behind the lamp assembly for access and disconnect the electrical connector.
3. Locate the bulb retaining ring behind the headlamp assembly.
4. Remove the bulb retaining ring by turning it counterclockwise
and remove the old bulb by
gently pulling it straight back
out of the lamp assembly. Keep
the retaining ring to retain the
new bulb.
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 hands could cause the bulb
to break the next time the headlamps are operated. Always wear
safety glasses while handling bulbs.
NOTE: If the bulb is accidentally touched, it should be cleaned with
rubbing alcohol before being used. 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 “stop.”
3. Install the electrical connector into the plastic base until it snaps, locking it into position.
4. 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.

hood.
2. Remove the screw from lamp assembly.

Driving while you tow
When towing a trailer:
• Keep your speed no faster than 70 mph (112 km/h) during the first
500 miles (800 km) of towing a trailer, and don’t make full throttle
starts.
• Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
• Consult your local motor vehicle speed regulations for towing a trailer.
• To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to the
Driving with a 5–speed automatic transmission section in the
Driving chapter.)
• Under extreme conditions with large frontal trailers, high outside
temperatures and highway speeds, the coolant gauge may indicate
higher than normal coolant temperatures. If this occurs, reduce speed
until the coolant temperature returns to the normal range. Refer to
Engine coolant temperature gauge in theInstrument Cluster
chapter.

When starting a fuel-injected engine, don’t press the accelerator before
or during starting. Only use the accelerator when you have difficulty
starting the engine. For more information on starting the vehicle, refer to
Starting the enginein this chapter.
WARNING: Extended idling at high engine speeds can produce
very high temperatures in the engine and exhaust system,
creating the risk of fire or other damage.
WARNING: Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.
WARNING: Do not start your vehicle in a closed garage or in
other enclosed areas. Exhaust fumes can be toxic. Always open
the garage door before you start the engine. See Guarding
against exhaust fumes in this chapter for more instructions.
WARNING: If you smell exhaust fumes inside your vehicle,
have your dealer inspect your vehicle immediately. Do not drive
if you smell exhaust fumes.
Important safety precautions
When the engine starts, the idle RPM runs faster to warm the engine. If
the engine idle speed does not slow down automatically, have the vehicle
checked.
Before starting the vehicle: 1. Make sure all occupants buckle their seat belts. For more information on seat belts and their proper usage, refer to the
Seating and Safety Restraints chapter.
2. Make sure the headlamps and electrical accessories are off.
