Ending Cruise Control
There are four ways to turn off the cruise control:
·Step lightly on the brake pedal,
·move the cruise control switch to off, or
·shift the transmission to NEUTRAL (N).
·If your vehicle has the Stabilitrakžfeature, cruise
control will turn off if road conditions cause
Stabilitrak
žto activate.

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
ªInstrument Panel Brightness Controlº 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 ªDaytime Running Lamps (DRL)º 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
®rst 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.
