2007 GMC ACADIA brake

Shifting Out of Park (P)
Your vehicle has an automatic transmission shift
lock control system. You have to apply your
regular brake rst and then press the shift lever
button before you can shift from PARK (P).
SeeAutomatic Transmission Operation on
page 129.
If you cannot shift out of PARK (P), ease pressure
on the shift lever and push the shift lever all the
way into PARK (P) as you maintain brake
application. Then press the shift lever button and
move the shift lever into the gear you wish.
Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot
exhaust parts under your vehicle and
ignite. Do not park over papers, leaves,
dry grass, or other things that can burn.

Running the Engine While Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust
into your vehicle. See the earlier caution
underEngine Exhaust on page 138.
Also, idling in a closed-in place can let
deadly carbon monoxide (CO) into your
vehicle even if the climate control fan is at
the highest setting. One place this can
happen is a garage. Exhaust — with
CO — can come in easily. NEVER park in
a garage with the engine running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 356.
{CAUTION:
It can be dangerous to get out of your
vehicle if the shift lever is not fully in
PARK (P) with the parking brake rmly
set. Your vehicle can roll. Do not leave
your vehicle when the engine is running
unless you have to. If you have left the
engine running, the vehicle can move
suddenly. You or others could be injured.
To be sure your vehicle will not move,
even when you are on fairly level ground,
always set the parking brake and move
the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on
page 135.
If you are pulling a trailer, seeTowing a Trailer on
page 371.

Floor Mats
There is a grommet in the driver side oor mat
that attaches to a hook on the oor of the vehicle.
This allows the mat to remain in position under
your feet and out of reach of the accelerator and
brake pedal. To remove the oor mat, pull the
mat towards the rear of the vehicle until the
grommet can be removed from the hook.
Make sure that the driver side oor mat is properly
placed on the oor so that it does not block the
movement of the accelerator and brake pedal.
Luggage Carrier
{CAUTION:
If you try to carry something on top of
your vehicle that is longer or wider than
the luggage carrier — like paneling,
plywood, a mattress and so forth — the
wind can catch it as you drive along. This
can cause you to lose control. What you
are carrying could be violently torn off,
and this could cause you or other drivers
to have a collision, and of course damage
your vehicle. You may be able to carry
something like this inside. But, never
carry something longer or wider than the
luggage carrier on top of your vehicle.

Cruise Control
With cruise control, you can maintain a speed
of about 25 mph (40 km/h) or more without
keeping your foot on the accelerator. This can
really help on long trips. Cruise control does not
work at speeds below about 25 mph (40 km/h).
When you apply your brakes, cruise control
is turned off.
{CAUTION:
Cruise control can be dangerous where
you cannot drive safely at a steady speed.
So, do not use your cruise control on
winding roads or in heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could
lose control. Do not use cruise control
on slippery roads.The cruise control
buttons are located
on left side of the
steering wheel.T(On/Off):Press this button to turn cruise
control on and off. The indicator comes on when
cruise control is on.
+ RES (Resume/Accelerate):Press this button
to make the vehicle accelerate or resume to
a previously set speed.
SET–:Press this button to set the speed or make
the vehicle decelerate.
[(Cancel):Press this button to cancel cruise
control.
180

Setting Cruise Control
Cruise control will not work if your parking brake
is set, or if the master cylinder brake uid
level is low.
The cruise control light on the instrument panel
cluster comes on after the cruise control has
been set to the desired speed.
{CAUTION:
If you leave your cruise control on when
you are not using cruise, you might hit a
button and go into cruise when you do not
want to. You could be startled and even
lose control. Keep the cruise control switch
off until you want to use cruise control.
1. Press the cruise control on/off button.
2. Get up to the speed desired.
3. Press and release the SET– button located
on the steering wheel.
4. Take your foot off the accelerator.
Resuming a Set Speed
Suppose you set your cruise control at a desired
speed and then you apply the brake. This
shuts off the cruise control. But you do not need
to reset it.
Once you are driving about 25 mph (40 km/h) or
more, press the +RES button on your steering
wheel. The vehicle will go back to the previously
chosen speed and stay there.
Increasing Speed While Using
Cruise Control
To increase the cruise speed while using cruise
control:
Press and hold the +RES button on the
steering wheel until you reach the desired
speed, then release it.
To increase vehicle speed in small increments,
press the +RES button.
181

Reducing Speed While Using
Cruise Control
To reduce your speed while using cruise control:
Press and hold the SET– button on the
steering wheel until you reach the lower speed
desired, then release it.
To slow down in very small amounts, press
the SET– button on the steering wheel
briey. Each time this is done, the vehicle will
go about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to increase vehicle
speed. When you take your foot off the pedal,
your vehicle will slow down to the previously set
cruise speed.
Using Cruise Control on Hills
How well your cruise control will work on hills
depends upon the vehicle speed, load, and the
steepness of the hills. When going up steep hills,
you might have to step on the accelerator pedal
to maintain the vehicle speed. When going
downhill, you might have to brake or shift to a
lower gear to keep the vehicle speed down.
Of course, applying the brake turns off the cruise
control. Many drivers nd this to be too much
trouble and do not use cruise control on steep hills.
Ending Cruise Control
There are three ways to end cruise control:
Step lightly on the brake pedal.
Press the[(cancel) button on the steering
wheel.
Press theT(on/off) button on the steering
wheel.
Erasing Speed Memory
The cruise control set speed memory is erased by
turning off the cruise control or the ignition.
182

The system does not work at a reverse speed
greater than 5 mph (8 km/h). To remind you of this,
the red light on the rear display will ash.
To disable URPA, seeDIC Operation and Displays
(With DIC Buttons) on page 233andDIC
Operations and Displays (Without DIC Buttons)
on page 239.
URPA automatically turns back on each time
the vehicle is started.
How the System Works when Backing
If the shift lever is in REVERSE (R), URPA
detects objects close to the rear bumper. The
rst time an object is detected a single beep will
sound. If an object is detected at a REVERSE (R)
speed between 0 mph (0 km/h) and 5 mph
(8 km/h), the following describes what will occur
based on your distance to a detected object
located behind the vehicle:
At distances between 40 inches (1 m) and 8 ft
(2.5 m), a single amber light will come on.
At distances between 23 inches (0.6 m) and
40 inches (1 m), both amber lights will be on.
At distances between 12 inches (0.3 m) and
23 inches (0.6 m), all three lights (amber/
amber/red) will be on.
At distances less than 12 inches (0.3 m), a
beeping sound will repeat for a short time and
all three lights (amber/amber/red) will ash.
When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a
temporary condition, the message PARK ASSIST
OFF will display on the DIC screen and a red
light will come on the URPA display when the shift
lever is moved into REVERSE (R). This occurs
under the following conditions:
The parking brake pedal is depressed.
A trailer was attached to your vehicle, or a
bicycle or an object was hanging out of
your trunk during your last drive when you
turned off the vehicle. If the attached objects
are removed from your vehicle before the start
of your next drive, the system will return to
normal operation unless an object is detected
when the vehicle is shifted into REVERSE (R).
