Infants and Young Children
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes
the need, for everyone, to use safety restraints. In fact,
the law in every state in the United States and in
every Canadian province says children up to some age
must be restrained while in a vehicle.{CAUTION:
Children can be seriously injured or strangled if a
shoulder belt is wrapped around their neck and
the safety belt continues to tighten. Never leave
children unattended in a vehicle and never allow
children to play with the safety belts.
Airbags plus lap-shoulder belts offer protection for
adults and older children, but not for young children and
infants. Neither the vehicle’s safety belt system nor
its airbag system is designed for them. Every time
infants and young children ride in vehicles, they should
have the protection provided by appropriate child
restraints.
Children who are not restrained properly can strike
other people, or can be thrown out of the vehicle.

Manual Operation of Power Liftgate
To change the liftgate to manual operation, press the
switch on the overhead console to the OFF position.
With the power liftgate disabled and all of the doors
unlocked, the liftgate can be manually opened and
closed.
To open the liftgate, press the touchpad on the handle
on the outside of the liftgate, and lift the gate open.
To close the liftgate, use the pull cup to lower the liftgate
and close. The liftgate latch will power close. Always
close the liftgate before driving.
If the RKE button or the power close button on the liftgate
is pressed while power operation is disabled, the lights
will ash three times, but the liftgate will not move.
It is not recommended that you drive with the liftgate
open, however, if you must drive with the liftgate open,
the liftgate should be set to manual operation by
pressing the OFF switch on the center console.
The liftgate has an electric latch. If the battery is
disconnected or has low voltage, the liftgate will not
open. The liftgate will resume operation when the battery
is reconnected and charged.
If the battery is properly connected with adequate
voltage, the switch is not disabled, and the liftgate still will
not function, your vehicle should be taken to a dealer/
retailer for service.
Power Assist Steps
Your vehicle may have power assist steps.
The power assist steps automatically extend from
beneath the vehicle on the side in which the door has
been opened. Once the door is closed, the assist steps
automatically move back under the vehicle after a
brief delay. The vehicle must not be moving for the
assist steps to extend or retract.
The switch used to disable
the power assist steps is
located on the center
console below the climate
control system.
The assist steps cannot be disabled in the extended
position.

Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts, let go
of the key. The idle speed will go down as the engine
gets warm. Do not race the engine immediately after
starting it. Operate the engine and transmission
gently to allow the oil to warm up and lubricate all
moving parts.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is turned
to the START position, and then released when the
engine begins cranking, the engine will continue
cranking for a few seconds or until the vehicle starts.
If the engine does not start and the key is held in
START for many seconds, cranking will be stopped
after 15 seconds to prevent cranking motor damage.
To prevent gear damage, this system also prevents
cranking if the engine is already running. Engine
cranking can be stopped by turning the ignition
switch to the ACC/ACCESSORY or LOCK/OFF
position.
Notice:Cranking the engine for long periods of
time, by returning the key 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 5-10 seconds,
especially in very cold weather (below 0°F or−18°C),
it could be ooded with too much gasoline.
Try pushing the accelerator pedal all the way to
the oor and holding it there as you hold the key in
START for up to a maximum of 15 seconds. Wait
at least 15 seconds between each try, to allow the
cranking motor to cool down. When the engine starts,
let go of the key and accelerator. If the vehicle starts
briey 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.
Notice:The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, the
engine might not perform properly. Any resulting
damage would not be covered by the vehicle
warranty.

When the System Does Not Seem To
Work Properly
The rear vision camera system might not work properly
or display a clear image if:
The RVC is turned off. See “Turning the Rear
Camera System On or Off” earlier in this section.
It is dark.
The sun or the beam of headlights is shining
directly into the camera lens.
Ice, snow, mud, or anything else builds up on the
camera lens. Clean the lens, rinse it with water,
and wipe it with a soft cloth.
The back of the vehicle is in an accident, the
position and mounting angle of the camera
can change or the camera can be affected. Be sure
to have the camera and its position and mounting
angle checked at your dealer/retailer.
There are extreme temperature changes.The rear vision camera system display in the rearview
mirror may turn off or not appear as expected due to
one of the following conditions. If this occurs the
left indicator light on the mirror will ash.
A slow ash may indicate a loss of video signal, or
no video signal present during the reverse cycle.
A fast ash may indicate that the display has
been on for the maximum allowable time during
a reverse cycle, or the display has reached an
Over Temperature limit.
The fast ash conditions are used to protect the
video device from high temperature conditions.
Once conditions return to normal the device will
reset and the green indicator will stop ashing.
During any of these fault conditions, the display will be
blank and the indicator will continue to ash as long
as the vehicle is in R (Reverse) or until the conditions
return to normal.
Pressing and holding
zwhen the left indicator light is
ashing will turn off the video display along with the
left indicator light.

OnStar service at any particular time or place. Some
examples are damage to important parts of the vehicle
in a crash, hills, tall buildings, tunnels, weather or
wireless phone network congestion.
Your Responsibility

There is a delay in the transition between the daytime and
nighttime operation of the Daytime Running Lamps (DRL)
and the automatic headlamp systems so that driving
under bridges or bright overhead street lights does not
affect the system. The DRL and automatic headlamp
system is only affected when the light sensor detects a
change in lighting lasting longer than the delay.
If the vehicle is started in a dark garage, the automatic
headlamp system will come on immediately. Once
the vehicle leaves the garage, it takes approximately
one minute for the automatic headlamp system to
change to DRL if it is bright enough outside. During that
delay, the instrument panel cluster may not be as
bright as usual. Make sure the instrument panel
brightness control is in the full bright position. See
Instrument Panel Brightness on page 3-18.
To idle the vehicle with the automatic headlamp system
off, turn the control to the off position.
The headlamps will also stay on after you exit the
vehicle. This feature can be programmed using the
Driver Information Center (DIC). SeeDIC Vehicle
Customization (With DIC Buttons) on page 3-74.
The regular headlamp system can be turned on when
needed.Fog Lamps
For vehicles with fog lamps, the control is located next
to the exterior lamps control on the instrument panel,
to the left of the steering column.
The ignition must be in the ON/RUN position for the fog
lamps to come on.
#(Fog Lamps):Press to turn the fog lamps on or off.
A light will come on in the instrument panel cluster.
When the fog lamps are turned on, the parking lamps
automatically turn on.
When the headlamps are changed to high-beam, the
fog lamps also go off. When the high-beam headlamps
are turned off, the fog lamps will come on again.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
