Automatic Headlamps
If the vehicle is equipped with a rain-light sensor and
the headlamp switch is in the 'A' position, the low
beam headlamps and all exterior lamps activate
when the outside light decreases to a pre-set level.
See Fig. 4.5.
Some vehicles may have a feature that automatically
turns on the headlamps if the windshield wipers are
on and the vehicle is moving faster than 10 mph (16
km/h). At speeds from 10 to 40 mph (16 to 64 km/h),
cycling the headlamp switch turns the headlamps off.

the turn signal lever is pushed away from the driver
in the high-beam position. See
When a vehicle approaches from the opposite
direction, the high-beam headlamps deactivate and
the low-beam headlamps activate. The high-beam
headlamps activate again when there are no vehicles
approaching from the opposite direction.
Auxiliary High Beam Lamps
If present, auxiliary high-beam lamps are located in
the front bumper. To activate the auxiliary high beam
lamps, press the upper part of the dash switch. The
auxiliary high beam lamps illuminate only when the
high-beam headlamps are on. They switch off
temporarily when the low-beam headlamps are on,
until the high beams are on again. Press the upper
half of the switch to deactivate the auxiliary high
beam lamps. See Fig. 4.6.

released. The DRL turn off when the engine falls
below 400 rpm, the parking brake is applied, or the
headlamps are turned on.
Daytime running lamps are mandatory for vehicles
domiciled in Canada. Vehicles domiciled in any other
location may have an optional override switch. See
Fig. 4.6, ref. 3. This is a momentary switch that
enables the driver to deactivate the DRL.
Fog Lamps

conditions. The marker lamps or headlamps must be
on in order to turn the fog lamps on. Pull the
headlamp switch outward to activate the fog lamps.

and trailer, as well as the turn signal indicators in the
ICU, flash simultaneously when the hazard lamps are
activated.
Marker Lamps
To turn the marker lamps on, turn the headlamp
switch clockwise past the off position. See
