Daytime Running
Lamps (DRL)
DRL can make it easier for others to
see the front of your vehicle during
the day. Fully functional DRL are
required on all vehicles first sold in
Canada.
The DRL system turns on the
low-beam headlamps at a reduced
brightness. For vehicles with High
Intensity Discharge (HID)
headlamps, there is a dedicated DRL. The DRL will come on when
all of the following conditions
are met:
.
The ignition is on.
. The exterior lamp control is
in AUTO.
. The light sensor determines it is
daytime.
. The vehicle is not in P (Park).
When the DRL are on, the taillamps,
sidemarker lamps, instrument panel
lights, and other lamps will not
be on.
The DRL turn off when the
headlamps are turned to
Oor the
ignition is off. For vehicles first sold
in Canada, the DRL can only be
turned off when the transmission is
in P (Park).
This vehicle may have a DRL
disabling function. When the DRL
are on and a turn signal is activated,
the DRL on that side will be off until
the turn signal goes off.

Automatic Headlamp
System
When the exterior lamp control is
set to AUTO and it is dark enough
outside, the headlamps come on
automatically.
There is a light sensor on top of the
instrument panel. Do not cover the
sensor, otherwise the headlamps
will come on when they are not
needed.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it
is light outside when the vehicle
leaves the garage, there is a slight
delay before the automatic
headlamp system changes to the
DRL. During that delay, the
instrument cluster may not be as
bright as usual. Make sure the
instrument panel brightness control
is in the full bright position. See
Instrument Panel Illumination
Control
0128.
When it is bright enough outside,
the headlamps will turn off or may
change to Daytime Running
Lamps (DRL).
The automatic headlamp system
turns off when the exterior lamp
control is turned toOor the ignition
is off.
Lights On with Wipers
If the windshield wipers are
activated in daylight with the engine
on, and the exterior lamp control is
in AUTO, the headlamps, parking
lamps, and other exterior lamps come on. The transition time for the
lamps coming on varies based on
wiper speed. When the wipers are
not operating, these lamps turn off.
Move the exterior lamp control to
P

change is completed. If the lever is
briefly pressed and released, the
turn signal flashes three times.
The turn and lane-change signal
can be turned off manually by
moving the lever back to its original
position.If after signaling a turn or lane
change, the arrow flashes rapidly or
does not come on, a signal bulb
may be burned out.
Have any burned out bulbs
replaced. If a bulb is not burned out,
check the fuse. See

Manual Mode
Driver Shift Control (DSC)
To use this feature, if equipped:1. Move the shift lever from D (Drive) rearward to
M (Manual Mode).
While driving in Manual Mode,
the transmission will remain in
the driver selected gear. When
coming to a stop in the manual
position, the vehicle will
automatically shift into
1 (First) gear.
2. Using the button on the shift lever, press the + (plus) end of
the button to upshift, or press
the−(minus) end of the button
to downshift.
The Driver Information Center (DIC)
in the instrument cluster will change
from the currently displayed
message to the letter “M,”for
Manual position, and a number
indicating the requested gear. While using the DSC feature the
transmission will have firmer shifting
and sportier performance. You can
use this for sport driving or when
climbing hills to stay in gear longer
or to downshift for more power or
engine braking.
The transmission will only allow you
to shift into gears appropriate for the
vehicle speed and engine
revolutions per minute (rpm):
.
The transmission will not allow
shifting to the next higher gear if
the vehicle speed or engine rpm
is too low.
. The transmission will not allow
shifting to the next lower gear if
the vehicle speed or engine rpm
is too high.
Second Gear Start Feature
When accelerating the vehicle from
a stop in snowy and icy conditions,
you may want to shift into
2 (Second) gear. A higher gear
allows you to gain more traction on
slippery surfaces. With the DSC feature, the vehicle
can be set to pull away in
2 (Second) gear.
1. Move the shift lever from D (Drive) to M (Manual Mode).
2. With the vehicle stopped, press the + (plus) end of the button to
select 2 (Second) gear. The
vehicle will start from a stop
position in 2 (Second) gear.
3. Once moving, select the desired drive gear.

164 Driving and Operating
vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used and
TCS or StabiliTrak/ESC begins to
limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow.
SeeIf the Vehicle Is Stuck 0147
and “Turning the Systems Off and
On” later in this section.
The indicator light for both systems
is in the instrument cluster. This
light will:
.
Flash when TCS is limiting
wheel spin.
. Flash when StabiliTrak/ESC is
activated.
. Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC), and
dcomes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly.
If
dcomes on and stays on:
1. Stop the vehicle. 2. Turn the engine off and wait
15 seconds.
3. Start the engine.
Drive the vehicle. If
dcomes on
and stays on, the vehicle may need
more time to diagnose the problem.
If the condition persists, see your
dealer.
Turning the Systems Off
and On
The button for TCS and StabiliTrak/
ESC is on the center console,
behind the shift lever.
Caution
Do not repeatedly brake or
accelerate heavily when TCS is
off. The vehicle driveline could be
damaged.

Cruise Control
With cruise control, you can
maintain a speed of about 40 km/h
(25 mph) or more without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
If equipped with the Traction Control
System (TCS), the system may
begin to limit wheel spin while you
are using cruise control. If this
happens, the cruise control will automatically disengage. See
Traction Control/Electronic Stability
Control
0163. If a collision alert
occurs when cruise control is
activated, cruise control is
disengaged. See Forward Collision
Alert (FCA) System 0178. When
road conditions allow you to safely
use it again, the cruise control can
be turned back on.
If the brakes are applied, the cruise
control disengages.
