2009 GMC ACADIA trunk

Liftgate
{CAUTION
Exhaust gases may enter the
vehicle if it is driven with the
liftgate, trunk/hatch open, or with
any objects that pass through the
seal between the body and the
trunk/hatch or liftgate. Engine
exhaust contains Carbon
Monoxide (CO) which cannot be
seen or smelled. It can cause
unconsciousness and even death.
If the vehicle must be driven with
the liftgate, or trunk/hatch open:
Close all of the windows.
Fully open the air outlets on
or under the instrument
panel.
(Continued)
CAUTION (Continued)
Adjust the Climate Control
system to a setting that
brings in only outside air and
set the fan speed to the
highest setting. See Climate
Control System in the Index.
If the vehicle is equipped with
a power liftgate, disable the
power liftgate function.
For more information about
carbon monoxide, seeEngine
Exhaust on page 2-30.
If the vehicle has a power liftgate,
seePower Liftgate on page 2-11.
To unlock the liftgate, use the power
door lock switch or press the door
unlock button on the Remote
Keyless Entry (RKE) transmitter
twice. SeeRemote Keyless Entry
(RKE) System Operation on
page 2-3.To open the liftgate, press the
touchpad on the underside of the
liftgate handle. The vehicle must be
in P (Park) to open the liftgate.
To close the liftgate, use the pull cup
or pull strap as an aid.
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
and has adequate voltage, and
the liftgate still will not function, the
vehicle should be taken to a
dealership/retailer for service.

in P (Park) to use the power feature.
The taillamps will ash and a
chime will sound when the power
liftgate is used.
{CAUTION
You or others could be injured if
caught in the path of the power
liftgate. Make sure there is no one
in the way of the liftgate as it is
opening and closing.
Notice:If you open the liftgate
without checking for overhead
obstructions such as a garage
door, you could damage the
liftgate or the liftgate glass.
Always check to make sure the
area above and behind the liftgate
is clear before opening it.
The power liftgate can be
power opened and closed in the
following ways:

Features and Controls 2-11

If the vehicle has a voltmeter gage
or a voltage display on the Driver
Information Center (DIC), you
may see the voltage move up or
down. This is normal. If there
is a problem, an alert will be
displayed.
The battery can be discharged at
idle if the electrical loads are
very high. This is true for all
vehicles. This is because the
generator (alternator) may not be
spinning fast enough at idle to
produce all the power that is needed
for very high electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, fog
lamps, rear window defogger,
climate control fan at high speed,
heated seats, engine cooling
fans, trailer loads, and loads
plugged into accessory power
outlets.EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator’s
output and the vehicle’s electrical
needs. It can increase engine
idle speed to generate more power,
whenever needed. It can temporarily
reduce the power demands of
some accessories.
Normally, these actions occur in
steps or levels, without being
noticeable. In rare cases at the
highest levels of corrective action,
this action may be noticeable
to the driver. If so, a Driver
Information Center (DIC) message
might be displayed, such as
BATTERY SAVER ACTIVE,
BATTERY VOLTAGE LOW, or
LOW BATTERY. If this message is
displayed, it is recommended
that the driver reduce the electrical
loads as much as possible. See
DIC Warnings and Messages
on page 3-56.Battery Run-Down
Protection
This feature helps prevent the
battery from being drained, if the
interior courtesy lamps, reading/map
lamps, visor vanity lamps or trunk
lamp are accidentally left on.
If any of these lamps are left on,
they automatically turn off after
10 minutes, if the ignition is off.
The lamps will not come back on
again until one of the following
occurs:
The ignition is turned on.
The exterior lamps control is
turned off, then on again.
The headlamps will timeout after
10 minutes, if they are manually
turned on before the ignition is off.
3-16 Instrument Panel

This would allow fuel to
evaporate into the atmosphere.
SeeMalfunction Indicator Lamp
on page 3-41.
If the vehicle has a Driver
Information Center (DIC), the
TIGHTEN GAS CAP message
displays if the fuel cap is not
properly installed.
{CAUTION
If a re starts while you are
refueling, do not remove the
nozzle. Shut off the ow of fuel
by shutting off the pump or by
notifying the station attendant.
Leave the area immediately.
Notice:If you need a new fuel
cap, be sure to get the right type.
Your dealer/ retailer can get one
for you. If you get the wrong type,
it might not t properly. This can
cause the malfunction indicator
lamp to light and can damage the
fuel tank and emissions system.
SeeMalfunction Indicator Lamp
on page 3-41.
Filling a Portable Fuel
Container
{CAUTION
Never ll a portable fuel container
while it is in the vehicle. Static
electricity discharge from the
container can ignite the fuel
vapor. You can be badly burned
and the vehicle damaged if this
occurs. To help avoid injury to
you and others:
Dispense fuel only into
approved containers.
Do not ll a container while it
is inside a vehicle, in a
vehicle’s trunk, pickup bed, or
on any surface other than the
ground.
(Continued)
CAUTION (Continued)
Bring the ll nozzle in contact
with the inside of the ll
opening before operating the
nozzle. Contact should be
maintained until the lling is
complete.
Do not smoke while
pumping fuel.
Do not use a cellular phone
while pumping fuel.
