Lighting Features
Entry Lighting
Some exterior lamps and most of the
interior lights turn on briefly at night,
or in areas of limited lighting when
K
is pressed on the Remote Keyless
Entry (RKE) transmitter. SeeRemote
Keyless Entry (RKE) System Operation
0 29. When the driver door is opened,
all control lights, Driver Information
Center (DIC) lights, and door pocket
lights turn on. After about 30 seconds
the exterior lamps turn off, then the
remaining interior lights dim to off.
Entry lighting can be disabled
manually by changing the ignition out
of the OFF position, or by pressing
Q
on the RKE transmitter.
This feature can be changed. See
“Vehicle Locator Lights” underVehicle
Personalization 0157. Entry Lighting with Approach
Detection
If equipped with approach detection,
the entry lighting feature will
automatically turn on when the RKE
transmitter is detected within
approximately 2 m (6 ft) of the vehicle.
If the vehicle has remained parked for
an extended period of time with no
RKE transmitter use or Keyless Access
operation, approach detection will be
disabled. To reactivate, press any
button on the RKE transmitter or
open and close all vehicle doors to
re-enable the entry lighting feature on
approach.
Approach detection will not work if:
.
The vehicle battery is low.
. The ignition is on or in ACC/
ACCESSORY.
. Entry lighting is set to Off. See
“Vehicle Locator Lights” under
Vehicle Personalization 0157. Approach detection will not work with
a single RKE transmitter if:
.
The RKE transmitter is left within
a 5 m (16 ft) range of the vehicle
for several minutes
. The RKE transmitter is left inside
the vehicle and all the doors are
closed
To help maximize transmitter battery
life, do not store the transmitter
within 5 m (16 ft) of the vehicle.
Exit Lighting
Some exterior lamps and interior
lights come on at night, or in areas
with limited lighting, when the driver
door is opened after the ignition is
turned off. The dome lamp comes on
after the ignition is turned off. The
exterior lamps and dome lamp remain
on for a set amount of time, then
automatically turn off.
The exterior lamps turn off

lamp control off.
This feature can be changed. See
Vehicle Personalization 0157.

DRIVING AND OPERATING 201
.Do not participate in track events,
sport driving schools, or similar
activities during this break-in
period.
. Check engine oil with every
refueling and add if necessary. Oil
and fuel consumption may be
higher than normal during the
first 2 400 km (1,500 mi).
. To break in new tires, drive at
moderate speeds and avoid hard
cornering for the first
300 km (200 mi). New tires do not
have maximum traction and may
tend to slip.
. New brake linings also need a
break–in period. Avoid making
hard stops during the first
300 km (200 mi). This is
recommended every time brake
linings are replaced.Ignition Positions
The vehicle has an electronic keyless
ignition with pushbutton start.
The Remote Keyless Entry (RKE)
transmitter must be in the vehicle for
the system to operate. If the
pushbutton start is not working, the
vehicle may be near a strong radio
antenna signal causing interference to
the Keyless Access system. See Remote
Keyless Entry (RKE) System Operation
0 29.
To shift out of P (Park), the ignition
must be on and the brake pedal must
be applied. Stopping the Engine/OFF (No
Indicator Lights) :
When the vehicle
is stopped, press ENGINE START/
STOP once to turn the engine off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory Power
(RAP) 0206.
If the vehicle is in R (Reverse),
D (Drive), or M (Manual Mode), the
vehicle will shift to P (Park), the
ignition will turn off, and RAP will
remain active.
If the vehicle is in N (Neutral), the
ignition will return to ACC/
ACCESSORY and display the message
SHIFT TO PARK in the Driver
Information Center (DIC). When the
vehicle is shifted into P (Park), the
ignition will turn off.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake and
steering systems and disable the
airbags.

DRIVING AND OPERATING 203
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped.
Caution
If you add electrical parts or
accessories, you could change the
way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty. See
Add-On Electrical Equipment0287.
Starting Procedure 1. With the Keyless Access system, the Remote Keyless Entry (RKE)
transmitter must be in the
vehicle. Press ENGINE START/
STOP with the brake pedal
applied. When the engine begins
cranking, let go of the button. The idle speed will go down as
the engine gets warm. Do not
race the engine immediately
after starting it.
If the RKE transmitter is not in
the vehicle, if there is
interference, or if the RKE
battery is low, a Driver
Information Center (DIC) will
display a message. See
Remote
Keyless Entry (RKE) System
Operation 029.
Caution
Cranking the engine for long
periods of time, by returning the
ignition to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down. 2. If the engine does not start after
five to 10 seconds, especially in
very cold weather (below −18 °C
or 0 °F), it could be flooded with
too much gasoline. Try pushing
the accelerator pedal all the way
to the floor and holding it there
as you press ENGINE START/
STOP. Wait at least 15 seconds
between each try, to allow the
cranking motor to cool down.
When the engine starts, release
the accelerator. If the vehicle
starts briefly but then stops
again, do the same thing. This
clears the extra gasoline from the
engine. Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Stop/Start System
If equipped, the Stop/Start system will
shut off the engine to help conserve
fuel. It has components designed for
the increased number of starts.

covered by the vehicle warranty.
Damage to vehicle components
resulting from modifications or the
installation or use of non-GM certified
parts, including control module or
software modifications, is not covered
under the terms of the vehicle
warranty and may affect remaining

complement and function with other
systems on the vehicle. See your
dealer to accessorize the vehicle using
genuine GM Accessories installed by a
dealer technician.
