the first detent position, the radio display and PRNDL

known as “parade” mode. The rest
of the I/P
illumination will stay
in the maximum dimming state
(full brilliance dimming). Turning the wheel up one
more detent will activate the interior dome light circuit
(with slightly higher effort).
The dome lights cannot be turned
on by depressing the
dome light switch button, located below the parWhead
lamp switch knob. This switch is a dome lamp off
switch and will only interrupt inputs from the door jamb
switches, inhibiting interior light operation when
depressed. It will not inhibit the light function from
the
I/P dimmer switch.

you to enter or exit your
vehicle with the lights staying on for about
20 seconds
after the door
is closed or ignition is cycled.

A tone will sound when your headlamps are turned on
and your ignition is in OFF, LOCK or ACCESSORY.

Daytime Running Lamps (If Equipped)
Daytime Running Lamps (Dm) can make it easier for
others
to see the front of your vehicle during the day.
DRL can be helpful
in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset.
The DRL system will make your headlamps come on at
a reduced brightness when:
The ignition is on,
The headlamp switch is off, and
0 The parking brake is released.
If your vehicle was first sold, when new,
in Canada,
your headlamps will come on at reduced brightness.
If your vehicle was first sold, when new, in the United
States, your vehicle may be equipped with DRL.
If your
vehicle has DRL, you
will see the the DRL indicator light
on your instrument panel and your low-beam
headlamps will come on at reduced brightness.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won’t be
on.
Your instrument panel won’t be lit up either.
When it begins to get dark, your
DRL indicator light is a
reminder to
turn your headlamp switch on. The other lamps
that come on
with your headlamps will also come on.
When
you turn off the headlamp switch, the regular
lamps will go
off, and your headlamps will change to
the reduced brightness of DRL.
To idle your vehicle with the engine on and the DRL off,
set the parking brake. The DRL will stay off until you
release
the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Dome Lamps
The dome lamps will come on when you open the doors.
You can also turn the dome lamps on by rotating the
thumb wheel, located next to the headlamp knob, all
the way up
to the second notch. In this position, the
dome lamps will remain
on whether the doors are
opened or closed.
