the vehicle is not moving.
To adjust the seat position:
1. Pull the handle under the front of the seat cushion.
2. Slide the seat to the desired position and release the handle.
3. Try to move the seat back and forth to be sure it is locked in

3-8 Seats and Restraints
Reclining Seatbacks
{WARNING
Sitting in a reclined position when
the vehicle is in motion can be
dangerous. Even when buckled
up, the safety belts cannot do
their job when reclined like this.(Continued)
WARNING (Continued)
The shoulder belt cannot do its
job because it will not be against
your body. Instead, it will be in
front of you. In a crash, you could
go into it, receiving neck or other
injuries.
The lap belt cannot do its job
either. In a crash, the belt could
go up over your abdomen.
The belt forces would be there,
not at your pelvic bones. This
could cause serious internal
injuries.
For proper protection when the
vehicle is in motion, have the
seatback upright. Then sit well
back in the seat and wear the
safety belt properly.
Manual Reclining Seatbacks
{WARNING
You can lose control of the
vehicle if you try to adjust a
manual driver seat while the
vehicle is moving. The sudden
movement could startle and
confuse you, or make you push
a pedal when you do not want to.
Adjust the driver seat only when
the vehicle is not moving.
{WARNING
If either seatback is not locked, it
could move forward in a sudden
stop or crash. That could cause
injury to the person sitting there.
Always push and pull on the
seatbacks to be sure they are
locked.

5-8 Instruments and Controls
Remove the cover to access and
replace when not in use.
Certain electrical accessories
may not be compatible with the
accessory power outlets and could
overload vehicle or adapter fuses.
If there is a problem, see your
dealer.
When adding electrical equipment,
be sure to follow the installation
instructions included with the
equipment. SeeAdd-On Electrical
Equipment on page 9‑62.
Notice: Hanging heavy
equipment from the power
outlet can cause damage not
covered by the vehicle warranty.
The power outlets are designed
for accessory power plugs only,
such as cell phone charge cords. Power Outlet 110 Volt Alternating
Current
The vehicle may have a power
outlet that can be used to plug
in electrical equipment with a
maximum limit of 150 watts.
The power outlet is located on the
rear of the center console.An indicator light on the outlet
comes on when in use. The light
comes on when the ignition is in
ON/RUN and equipment requiring
less than 150 watts is plugged into
the outlet, and no system fault is
detected.
If you try to connect equipment
using more than 150 watts or
a system fault is detected, the
equipment may operate for a
short period and turn itself off.
A protection circuit shuts off the
power supply and the indicator
light turns off. To reset the circuit,
unplug the item and plug it back
in or turn the Remote Accessory
Power (RAP) off and then back on.

5-32 Instruments and Controls
All formats will show the turn-by-turn
navigation information and provide
details about the next driving
maneuver to be made. When
you near your destination, the
HUD will display a distance bar
that will empty the closer you get
to your destination. All navigation
information is provided to the HUD
by the navigation radio or OnStar
®
service, for vehicles that have these
features.
English Shown, Metric Similar
The HUD image displayed on
the windshield will automatically
dim and brighten to compensate
for outside lighting. However, the
HUD brightness control can still
be adjusted as needed. The HUD image can temporarily
light up depending on the angle
and position of the sunlight on the
HUD display. This is normal and
will change when the angle of
the sunlight on the HUD display
changes.
Polarized sunglasses could make
the HUD image harder to see.
Care of the HUD
Clean the inside of the windshield
as needed to remove any dirt or film
that could reduce the sharpness or
clarity of the HUD image.
To clean the HUD lens, use a soft,
clean cloth that has household glass
cleaner sprayed on it. Wipe the
HUD lens gently, then dry it. Do not
spray cleaner directly on the lens
because the cleaner could leak into
the unit.
If You Cannot See the HUD
Image When the Ignition Is On
.Is anything covering the
HUD lens?
.Is the HUD dimmer setting bright
enough?
.Is the HUD image adjusted to
the proper height?
.Are you wearing polarized
sunglasses?
.Still no HUD image? Check the
fuse in the instrument panel fuse
block. See
Instrument Panel
Fuse Block on page 10‑42.
If the HUD Image Is Not Clear
.Is the HUD image too bright?
.Are the windshield and HUD
lens clean?
If the HUD image is not correct,
contact your dealer.
Keep in mind that the windshield is
part of the HUD system.

6-4 Lighting
Adaptive Forward
Lighting (AFL)
The Adaptive Forward Lighting
System (AFL) pivots the headlamps
horizontally to provide greater
road illumination while turning.
To enable AFL, set the exterior
lamp switch to the AUTO position.
Moving the switch out of the AUTO
position deactivates the system.
AFL operates when the vehicle
speed is greater than 3 km/h
(2 mph). AFL does not operate
when the transmission is in
R (Reverse). AFL is not immediately
operable after starting the vehicle;
driving a short distance is required
to calibrate the AFL. SeeExterior
Lamp Controls on page 6‑1.
Hazard Warning Flashers
|
Hazard Warning Flasher:
Press this button located on the
instrument panel below the climate
control system, to make the front
and rear turn signal lamps flash
on and off. Press again to turn the
flashers off.
The hazard warning flashers turn on
automatically if the airbags deploy.
Turn and Lane-Change
Signals
Move the lever all the way up or
down to signal a turn. An arrow on the instrument panel
cluster flashes in the direction of the
turn or lane change.
Raise or lower the lever until the
arrow starts to flash to signal a lane
change. Hold it there until the lane
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
might be burned out.
Have the bulbs replaced. If the bulb
is not burned out, check the fuse.
See
Fuses and Circuit Breakers on
page 10‑39.

Driving and Operating 9-23
2. If the engine does not start after5‐10 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 hold the key in START,
or press the START button, 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 or button, and 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.Engine Heater
The engine coolant heater,
if available, can help in cold weather
conditions at or below −18°C (0°F)
for easier starting and better fuel
economy during engine warm-up.
Plug in the coolant heater at least
four hours before starting the
vehicle. An internal thermostat in
the plug-end of the cord will prevent
engine coolant heater operation at
temperatures above −18°C (0°F).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
V6 Engine
The electrical cord is located
on the driver side of the
engine compartment, between
the fender and the engine
compartment fuse block on
vehicles with a six cylinder
engine.
