BULB REPLACEMENT
High Intensity Discharge Headlights (HID) Ð If
Equipped
The headlights are a type of high voltage discharge tube.
High voltage can remain in the circuit even with the
headlight switch off and the key removed.Because of
this, you should not attempt to service a headlight bulb
yourself. If a headlight bulb fails, take your vehicle to
an authorized dealer for service.
WARNING!
A transient high tension occurs at the bulb sockets of
High Intensity Discharge (HID) headlights when the
headlight switch is turned ON. It may cause serious
electrical shock or electrocution if not serviced prop-
erly. See your authorized dealer for service.
NOTE:On vehicles equipped with High Intensity Dis-
charge Headlights (HID), when the headlights are turned
on, there is a blue hue to the lights. This diminishes and
becomes more white after approximately 10 seconds, as
the system charges.

438 MAINTAINING YOUR VEHICLE

²Change your engine oil more often if you drive your
vehicle off-road for an extended period of time.
²Under no circumstances should oil change intervals
exceed 6,000 miles (10,000 km) or 6 months, whichever
comes first.
Your dealer will reset the oil change indicator message
after completing the scheduled oil change. If this sched-
uled oil change is performed by someone other than your
dealer the message can be reset by referring to the steps
described under ªOil Change Requiredº in ªUse Factory
Settingsº of the EVIC section in this manual.
At Each Stop for Fuel
²Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
²Check the windshield washer solvent and add if
required.
Once a Month
²Check tire pressure and look for unusual wear or
damage.
²Inspect the battery and clean and tighten the terminals
as required.
²Check the fluid levels of coolant reservoir, brake
master cylinder, power steering and transmission and
add as needed.
²Check all lights and other electrical items for correct
operation.
