PANEL DIMMER CONTROL
Use to adjust the brightness of the
instrument panel and all applicable
switches in the vehicle during
headlamp and parklamp operation.
Move the control to the full upright
position, past detent, to turn on the
interior lamps.
Move the control to the full down
position, past detent, to prevent the
interior lights from illuminating
when the doors are opened.
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.
VERTICAL AIM ADJUSTMENT
1. Park the vehicle on a level surface approximately 7.6 meters (25 feet)
from a vertical wall or screen directly in front of it.
• (1) Eight feet
• (2) Center height of lamp to ground
• (3) Twenty-five feet
• (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 a 2.4 meter (8
foot) horizontal reference line on
the vertical wall or screen at this
height (a piece of masking tape
works well).
3. Turn on the low beam headlamps
to illuminate the wall or screen and open the hood. Cover one of the
headlamps so no light hits the wall.

Front and second row safety belt height adjustment
Your vehicle has safety belt height
adjustments for the driver, right
front passenger and second row
outboard passengers. Adjust the
height of the shoulder belt so the
belt rests across the middle of your
shoulder.
To lower the shoulder belt height,
push the button and slide the height
adjuster down. To raise the height
of the shoulder belt, push the
button and slide the height adjuster
up. Pull down on the height adjuster
to make sure it is locked in place.
Position the safety belt
height adjusters so that the
belt rests across the middle of
your shoulder. Failure to adjust
the safety belt properly could
reduce the effectiveness of the
seat belt and increase the risk of
injury in a collision.
Safety belt warning light and indicator chime
The safety belt warning light illuminates in the instrument cluster and a
chime sounds to remind the occupants to fasten their safety belts.

(Overdrive) for 10 seconds, then return the gearshift lever to P (Park)
and release the brake. With the ignition still in the ON position, and all
doors closed, allow the vehicle to stand (without passengers) for several
minutes so that it can level.
2. Turn the air suspension (if equipped) control to OFF.
3. Measure the height of a reference point on the front and rear bumpers
at the center of the vehicle.
4. Attach the trailer to the vehicle and adjust the hitch equalizers so that
the front bumper height is within 0 – 13 mm (0.5 in) of the reference
point. After proper adjustment, the rear bumper should be no higher
than in Step 3.
5. Turn the air suspension (if equipped) control to ON.
Note: Adjusting an equalizing hitch so the rear bumper of the vehicle is
higher than it was unloaded will defeat the function of the load
equalizing hitch and may cause unpredictable handling.
Safety chains
Always connect the trailer ’ s safety chains to the frame or hook retainers
of the vehicle hitch. To connect the trailer ’ s safety chains, cross the
chains under the trailer tongue and allow slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer ’ s
specifications. The trailer brakes must meet local and Federal
regulations.
Do not connect a trailer ’ s hydraulic brake system directly to your
vehicle ’ s brake system. Your vehicle may not have enough
braking power and your chances of having a collision greatly increase.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. See your
dealer or trailer rental agency for proper instructions and equipment for
hooking up trailer lamps.
