Headlamps on Reminder
A warning chime will sound if the vehicle’s ignition is
off and the driver’s door is opened when the exterior
lamp control is left on in either the headlamp or
parking lamp position.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) 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. Daytime running
lamps are required to function at all times on all
vehicles rst sold in Canada.
A light sensor on top of the instrument panel makes
the DRL work, so be sure it is not covered.
The DRL system will make the low-beam headlamps
come on at reduced brightness when the following
conditions are met:
The ignition is on.
The exterior lamps control is off.
The parking brake is released.
While the DRL are on, only the vehicle’s low-beam
headlamps will be on at reduced brightness. The turn
signal, taillamps, sidemarker and other lamps will not be
on. The instrument panel cluster will not be lit up either.

Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left on
after the ignition has been turned to off, the exterior
lamps will turn off after about 10 minutes. This protects
the battery from being drained.
Use the exterior lamp control to turn the lamps back on,
if they are still needed.
Interior Lamps
The interior lamps can be controlled, or automatically
turn on or off under certain conditions. They are
explained in the following text.

panel lights.
The interior lamps

steering column.
Turn the control to adjust the brightness of the
instrument panel lights.

When a door is opened, the courtesy lamps will
automatically come on. These lamps will also come on
when the interior lamps control is fully turned clockwise.
