Lamps On Reminder
If you turn off the ignition and open the driver’s
door while leaving the lamps on, you will hear a
warning chime.
Daytime Running Lamps
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.
The DRL system will make your high - beam headlamps
come on at a reduced brightness when:
D the ignition is on,
D the headlamp switch is in OFF or you have turned on
your parking lamps,
D the light sensor detects daytime light,
D the parking brake is released and
D the shift lever is not in PARK (P).
When the DRL system is on, the taillamps, sidemarker
lamps, park lamps and instrument panel lights will not
be illuminated.
The DRL system will remain off any time your vehicle
is in PARK (P) or the parking brake is engaged and the
vehicle speed is less than 3 mph (1.9 km/h).
As with any vehicle, you should turn on the regular
headlamp system when you need it.
