BULB REPLACEMENT
Headlamp Condensation
The headlamps are vented to equalize pressure. When moist air enters
the headlamp(s) through the vents, there is a possibility that
condensation can occur. This condensation is normal and will clear
within 45 minutes of headlamp operation.
Using the right bulbs
Replacement bulbs are specified in the chart below. Headlamp bulbs
must be marked with an authorized “D.O.T.” for North America and an
“E” for Europe to ensure lamp performance, light brightness and pattern
and safe visibility. The correct bulbs will not damage the lamp assembly
or void the lamp assembly warranty and will provide quality bulb burn
time.

Automatic dimming rear view mirror (if equipped)
Your vehicle may be equipped with
an inside rear view mirror which has
an auto-dimming function. The
electronic day/night mirror will
change from the normal (high
reflective) state to the non-glare
(darkened) state when bright lights (glare) reach the mirror. When the
mirror detects bright light from behind the vehicle, it will automatically
adjust (darken) to minimize glare.
The mirror will automatically return to the normal state whenever the
vehicle is placed in R (Reverse) (when the mirror is on) to ensure a
bright clear view when backing up.
Do not block the sensors on the front and back of the inside rear
view mirror since this may impair proper mirror performance.
Do not clean the housing or glass of any mirror with harsh
abrasives, fuel or other petroleum-based cleaning products.
