•Rotate fully to the right (past detent) to turn on interior lamps.
•Rotate to the left position (past detent) to turn off the interior lamps
and will also disable the illuminated entry feature.
Note:If the battery is disconnected, discharged, or a new battery is
installed, the dimmer switch requires re-calibration. Rotate the dimmer
switch from the full dim position to the full Dome/ON position to reset.
This will ensure that your displays are visible under all lighting
conditions.
At dusk and dawn, the LEDs are illuminated at six times the normal
intensity to enhance contrast and visibility. The system automatically
“dims down” as ambient light reaches the dash-mounted sensor.
The interior control lights dim progressively in four steps until they
reach nighttime operating levels. At all illumination levels, the lights can
be dimmed using the thumbwheel on the instrument panel.
AIMING THE HEADLAMPS
The headlamps on your vehicle are properly aimed at the assembly plant.
If your vehicle has been in an accident the alignment of your headlamps
should be checked by your authorized dealer.
Vertical aim adjustment
Before aim adjustment, disable the air suspension system. Refer to
Messagecenter in theDriver Controlschapter.
1. Park the vehicle directly in front of a wall or screen on a level surface,
approximately 25 feet (7.6 meters) away.
•(1) 8 feet (2.4 meters)
•(2) Center height of lamp to
ground
•(3) 25 feet (7.6 meters)
•(4) Horizontal reference line
2. Measure the height from the
center of your headlamp (indicated
by a 3.0 mm circle on the lens) to
the ground and mark an 8 foot
(2.4 meter) horizontal reference line
on the vertical wall or screen at this height (a piece of masking tape
works well).

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 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 interior rear view mirror
Your vehicle is equipped with an interior 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.
Without voice activated
Navigation System
With voice activated Navigation
System
The mirror will automatically return to the normal state whenever the
vehicle is placed in R (Reverse) to ensure a bright clear view when
backing up.
Do not block the sensors on the front and back of the interior
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.
Note:If equipped with a Reverse Camera System, a video image will
display in the mirror when the vehicle is put in (R) reverse. Refer to
