cruise control GMC ACADIA 2007 Owner's Manual

When you shift from DRIVE (D) to LOW (L), the
transmission will shift to a pre-determined
lower gear range. The highest gear available for
this pre-determined range is displayed next to
the L in the DIC. SeeDriver Information Center
(DIC) on page 232andDIC Operation and
Displays (With DIC Buttons) on page 233orDIC
Operation and Displays (Without DIC Buttons)
on page 239for more information. The number
displayed in the DIC is the highest gear that
the transmission will be allowed to operate in.
However, your vehicle can automatically shift to
lower gears as required by various driving
conditions. This means that all gears below that
number are available. For example, when
FOURTH (4) is shown next to the L, FIRST (1)
through FOURTH (4) gears are automatically
shifted by the vehicle. You cannot shift into
FIFTH (5) until the plus (+) button is used or you
shift back into DRIVE (D) mode.While in LOW (L), the transmission will prevent
shifting to a lower gear range if the engine speed
is too high for the gear range you are trying to
select. You have a brief period of time to slow the
vehicle speed. If vehicle speed is not reduced
within the timeframe allowed, the lower gear range
attempted will not be available. The highest
possible gear that is allowed for that engine speed
will display next to the L in the DIC. Try again
to slow the vehicle speed and press the minus (−)
button to the desired lower gear range.
Automatic Engine Grade braking is not available
when the ERS is active. It is available in
DRIVE (D) for both normal and Tow/Haul mode.
While using the ERS, cruise control and the
tow/haul mode can be used. SeeTow/Haul Mode
on page 133for more information.

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.

CRUISE SET TO XXX
This message displays whenever the cruise control
is set. SeeCruise Control on page 180for more
information.
DRIVER DOOR OPEN
This message displays and a chime sounds if the
driver’s door is not fully closed and the vehicle
is in a drive gear. Stop and turn off the vehicle,
check the door for obstructions, and close the door
again. Check to see if the message still appears
on the DIC.
ENGINE HOT A/C (Air Conditioning) OFF
This message displays when the engine coolant
becomes hotter than the normal operating
temperature. SeeEngine Coolant Temperature
Gage on page 225. To avoid added strain on
a hot engine, the air conditioning compressor
automatically turns off. When the coolant
temperature returns to normal, the air conditioning
compressor turns back on. You can continue to
drive your vehicle.
If this message continues to appear, have the
system repaired by your dealer/retailer as soon
as possible to avoid damage to the engine.
ENGINE OIL LOW ADD OIL
If your vehicle has an oil level sensor, this
message displays if the oil level in the vehicle
is low. Check the oil level and correct it as
necessary. You may need to let the vehicle cool
or warm up and cycle the ignition to be sure
this message clears. SeeEngine Oil on page 397
for additional information.
ENGINE OVERHEATED IDLE ENGINE
Notice:If you drive your vehicle while the
engine is overheating, severe engine damage
may occur. If an overheat warning appears
on the instrument panel cluster and/or
DIC, stop the vehicle as soon as possible.
Do not increase the engine speed above
normal idling speed. SeeEngine Overheating
on page 410for more information.
This message displays when the engine coolant
temperature is too hot. Stop and allow the vehicle
to idle until it cools down. SeeEngine Coolant
Temperature Gage on page 225.
SeeOverheated Engine Protection Operating
Mode on page 412for information on driving to
a safe place in an emergency.

The traction control system may activate on
dry or rough roads or under conditions such as
heavy acceleration while turning or abrupt
upshifts/downshifts of the transmission.
When this happens, you may notice a reduction
in acceleration, or may hear a noise or vibration.
This is normal.
If your vehicle is in cruise control when the system
activates, the StabiliTrak
®light will ash and the
cruise control will automatically disengage.
When road conditions allow you to use cruise
again, you may re-engage the cruise control.
SeeCruise Control on page 180.
StabiliTrak
®may also turn off automatically if it
determines that a problem exists with the system.
If the problem does not clear itself after restarting
the vehicle, you should see your dealer/retailer
for service.
All-Wheel Drive (AWD) System
If your vehicle has this feature, engine power is
sent to all four wheels when extra traction is
needed. This is like four-wheel drive, but there
is no separate lever or switch to engage or
disengage the front axle. It is fully automatic, and
adjusts itself as needed for road conditions.
When using a compact spare tire on your AWD
equipped vehicle, the AWD system automatically
detects the presence of the compact spare
and the AWD is disabled. To restore the AWD
operation and prevent excessive wear on
the clutch in your AWD system, replace the
compact spare with a full-size tire as soon as
possible. SeeCompact Spare Tire on page 477
for more information.
