To drive your vehicle with the DRL off, turn off the
Twilight Sentinel
®
and manually turn on the parking
lamps or fog lamps (if equipped).
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Fog Lamps
If your vehicle has fog lamps, use them for better vision
in foggy or misty conditions.
The fog lamp button is
located to the left of the
steering wheel on the
instrument panel.
When you press the fog lamp button, a fog lamp symbol
in the button and the fog lamp light on the instrument
panel cluster will come on to indicate that the fog lamps
and the parking lamps are on.
Press the button again to turn them off.
If you turn on the high-beam headlamps, the fog lamps
will turn off. They’ll turn back on again when you
switch to low-beam headlamps.
When the Twilight Sentinel
®
is on and the fog lamps are
turned on, the fog lamps, headlamps and parking
lamps will remain on.
The ignition must be on for the fog lamps to operate.
Cornering Lamps
The cornering lamps come on when the headlamps or
parking lamps are on and you signal a turn with the
multifunction lever. They provide more light for cornering.
Twilight Sentinel
®
This lever is located next
to the exterior lamp
control. It automatically
turns the lamps on and off
by sensing how dark it
is outside.
