reducing the need to look away from the
road. The information appears as an
image toward the front of the vehicle.
The information displayed by the HUD
may include the speedometer reading,
RPM reading, transmission position,
outside air temperature, high-beam
headlamps and turn signal indicators, a
brief display of the current radio station
or CD track, and Turn-by-Turn
Navigation information (if equipped).
The following HUD controls are located
on the instrument panel to the right of
the steering wheel:
(Off): To turn off the HUD image,
rotate the dimming knob fully
counterclockwise.
Brightness: Rotate the dimming knob
clockwise to brighten and counterclock-
wise to dim the HUD image.
(Up) (Down):Press the up or
down arrow to adjust the position of the
HUD image on the windshield. (It cannot
be adjusted side-to-side.)

Getting to Know Your Acadia22
PERFORMANCE & MAINTENANCE
Refueling the Vehicle
To open the fuel door, press the center
of the rear edge of the door and it will
pop open slightly. Pull the door to open
it fully.
When closing the fuel door, press the
center of the rear edge of the door until
it is flush with the side of the vehicle.
See Section 5 of your Owner Manual.
Automatic Transmission
Operation
The automatic transmission has an
Electronic Range Select mode that
enables the driver to select the top-gear
limit desired for
the current driving
conditions, such
as when driving
on downhill
grades. This pro-
vides engine brak-
ing and reduces
brake wear.
StabiliTrak®– Stability Control
System
StabiliTrak is an advanced computer-
controlled vehicle stability and traction
enhancement system that assists with
directional control of the vehicle in
difficult driving conditions. It turns on
automatically every time you start your
vehicle.
To limit wheelspin and help maintain
directional control, you should always
leave the system on. However, if your
vehicle becomes stuck and rocking the
vehicle is required,
the system should be
turned off.
To turn off the traction
control part of the
system, press the
(Traction Control) button located on the
center console in front of the shift lever.
When the system is turned off, the
Traction Control light will illuminate.
See Section 4 of your Owner Manual.
To use this feature, move the shift lever
to the Low (L) range position and select
a lower or higher driving gear using the
+ / – button on the side of the shift lever.
The display on the instrument panel clus-
ter will show the current gear selection.
The transmission will be limited to the
gear selected and lower gears. Gears
higher than the gear selected will not be
available.
If current vehicle speed is too high or
too low for the requested gear, the shift
will not occur.
See Section 2 of your Owner Manual.
Canceling a Remote Start
If you wish to turn off the engine instead
of driving after a remote start, perform
one of the following functions:
• Press and hold the (Remote Start)
button until the parking lamps turn off.
• Press and release the Hazard
Warning Flashers button. Press it
again to turn off the flashers.
• Turn the key in the ignition switch to
the On position and then off.
See Section 2 of your Owner Manual.

The Tow/Haul mode (if equipped) assists

the frequency of transmission shifts and
improves the control of vehicle speed.
To turn on this feature,

Haul) button located on
the center console in
front of the shift lever.
Press it again to turn off the feature.
See Section 4 of your Owner Manual.
reappear if the tire pressure has not
been corrected.
During cooler conditions, the low tire
pressure warning light may appear when
the vehicle is first started and then turn
off as you start to drive. This could be
an early indicator that your tire pres-
sures are getting low and the tires need
to be inflated to the proper pressure.
See Section 5 of your Owner Manual.

Trailer Towing
Tire Pressure Monitor
The Tire Pressure Monitor alerts you
when a significant reduction in pressure
occurs in one or more of your vehicle’s
tires by illuminating the (Low Tire
Pressure) warning light on the instru-
ment panel. The low tire pressure
warning light will remain on until you
correct the tire pressure.
A CHECK TIRE PRESSURE message
may appear on the DIC.
Correcting the Tire Pressure
When the low tire pressure warning light
illuminates, you must inflate the tire to
the proper tire pressure (just as you
must refuel the vehicle when the low
fuel warning light illuminates). The Tire
and Loading Information label, located
on the center pillar below the driver’s
door latch, shows the correct tire
pressure for the tires when they’re cold.
“Cold” means your vehicle has been
sitting for at least three hours or driven
no more than one mile.
You can temporarily remove the DIC
message by acknowledging it with your
DIC controls. However, at the next
vehicle start-up, the DIC message will
Note:The Tire Pressure Monitor can alert
you about low tire pressure, but it doesn’t
replace normal monthly tire maintenance.
