Lights
PANEL DIMMER CONTROL
Use to adjust the brightness of the
instrument panel when exterior
lights are on.
• Rotate the thumbwheel from left
to right to brighten the
instrument panel.
• Rotate the thumbwheel from right
to left to dim the instrument
panel.
• 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 to disable the illuminated entry feature. When the control is in the
far left position, it acts as a dome lamp defeat/override.
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.
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
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).
