Wiper Activated Headlamps
This feature activates the headlamps and parking
lamps after the windshield wipers have been in
use for approximately 15 seconds and deactivates
and returns to ambient lighting conditions
15 seconds after the wipers are turned off.
If the exterior lamp control has been turned off or
is in the parking lamp position while the wiper
control is active in any position, the HEADLAMPS
SUGGESTED message appears on the Driver
Information Center (DIC). SeeDIC Warnings and
Messages on page 214.
When the ignition is turned off, the wiper-activated
headlamps will immediately turn off.
Headlamps on Reminder
A warning chime will sound if the exterior lamp
control is left on in either the headlamp or parking
lamp position and the driver’s door is opened
with the ignition off.
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. Fully functional daytime running lamps
are required on all vehicles rst sold in Canada.
The DRL system will make the front turn signal
lamps come on when the following conditions
are met:
It is still daylight and the ignition is on.
The exterior lamp control is in the
AUTO position.
The transmission is not in PARK (P) or
the parking brake is off.
The parking brake is off or the vehicle
speed is greater than 8 mph (13 km/h).
When DRL are on, only the front turn signal lamps
will be on. No other exterior lamps such as the
parking lamps, taillamps, etc. will be on when the
DRL are being used. Your instrument panel
will not be lit up either.

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the other
part can still work and stop you. For good
braking, though, you need both parts working well.
This light should come on when you start the
engine. If it does not come on then, have it xed
so it will be ready to warn you if there is a problem.
If this warning light stays on after you start the
engine, the parking brake may still be set or
there could be a brake problem. Refer to
Parking Brake on page 102to see if it is set.
If the parking brake is not set, have your brake
system inspected right away.If the light comes on while you are driving and you
have a CHECK BRAKE FLUID message showing
on the DIC, pull off the road and stop carefully.
You may notice that the pedal is harder to push or
the pedal may go closer to the oor. It may take
longer to stop. If the light is still on, have the
vehicle towed for service. SeeTowing Your
Vehicle on page 315andDIC Warnings and
Messages on page 214for more information.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.United StatesCanada
