Exterior Lamp Controls
The exterior lamp control is on the
instrument panel to the left of the steering
wheel.
There are four positions:
O : Turns off the automatic headlamps and
Daytime Running Lamps (DRL). Turn the
headlamp control to
O again to turn the
automatic headlamps or DRL back on.
For vehicles first sold in Canada, the off
position will only work when the vehicle is
shifted into P (Park).
AUTO : Automatically turns on the
headlamps, parking lamps, taillamps,
instrument panel lights, roof marker lamps
(if equipped), and license plate lamps.
; : Turns on the parking lamps including
all lamps, except the headlamps.
2 : Turns on the headlamps with the
parking lamps and instrument panel lights.
When the headlamps are turned on while
the vehicle is on, the headlamps turn off
automatically 10 minutes after the ignition
is turned off. When the headlamps are
turned on while the vehicle is off, the
headlamps will stay on for 10 minutes
before turning off to prevent the battery
from being drained. Turn the headlamp
control off and then back to the headlamp
on position to make the headlamps stay on
for an additional 10 minutes.
To keep the lamps on for more than
10 minutes, the ignition must be on or in
ACC/ACCESSORY.
IntelliBeam System
If equipped, this system turns the vehicle's
high-beam headlamps on and off according
to surrounding traffic conditions.
