If you start your vehicle in a dark garage, the automatic

headlamp system will come on immediately. Once

you leave the garage, it will take approximately

one minute for the automatic headlamp system to

change to DRL if it is bright enough outside. During that

delay, your instrument panel cluster may not be as

bright as usual. Make sure your instrument panel

brightness control is in the full bright position. See

“Instrument Panel Brightness Control” under

Interior

Lamps on page 3-19

To idle your vehicle with the automatic headlamp

system off, turn the control to the off position.

You may be able to turn off your Automatic Headlamp

System. See “Daytime Running Lamps (DRL)” later

in this section for more information.

As with any vehicle, you should turn on the regular

headlamp system when you need them.

Lamps On Reminder

A reminder chime will sound when your headlamps or

parking lamps are manually turned on and your ignition is

off, in LOCK, ACCESSORY, or your door is open. To

disable the chime, turn the light off then back on.

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. Fully functional

daytime running lamps are required on all vehicles

ﬁrst sold in Canada.

The DRL system will come on when the following

conditions are met:

• The ignition is on

• The exterior lamps control is in AUTO

• The automatic transmission is not in PARK (P)

• The light sensor determines it is daytime

When the DRL system is on, only your DRL lamps will

be on. The taillamps, sidemarker and other lamps

won’t be on. The instrument panel won’t be lit up either.

When it begins to get dark, the automatic headlamp

system will switch from DRL to the headlamps or the last

chosen headlamp setting that was used.

When you turn the headlamp switch off, the headlamps

will go off, and your DRL lamps will illuminate,

provided it is not dark outside.
