2008 GMC ACADIA park assist

To use the retro-active reset feature, press and hold
the trip odometer reset stem for at least four seconds.
The trip odometer will display the number of miles (mi)
or kilometers (km) driven since the ignition was last
turned on and the vehicle was moving. Once the
vehicle begins moving, the trip odometer will accumulate
mileage. For example, if the vehicle was driven
5 miles (8 km) before it is started again, and then
the retro-active reset feature is activated, the display
will show 5 miles (8 km). As the vehicle begins moving,
the display will then increase to 5.1 miles (8.2 km),
5.2 miles (8.4 km), etc.
If the retro-active reset feature is activated after
the vehicle is started, but before it begins moving,
the display will show the number of miles (mi) or
kilometers (km) that were driven during the last
ignition cycle.
OIL LIFE
To access this display, the vehicle must be in PARK (P).
Press the trip odometer reset stem until OIL LIFE
REMAINING displays. This display shows an estimate
of the oil’s remaining useful life. If you see 99% OIL LIFE
REMAINING on the display, that means 99% of the
current oil life remains. The engine oil life system
will alert you to change the oil on a schedule consistent
with your driving conditions.When the remaining oil life is low, the CHANGE
ENGINE OIL SOON message will appear on the
display. See “CHANGE ENGINE OIL SOON” under
DIC Warnings and Messages on page 3-66. You should
change the oil as soon as you can. SeeEngine Oil
on page 5-15. In addition to the engine oil life system
monitoring the oil life, additional maintenance is
recommended in the Maintenance Schedule in this
manual. SeeScheduled Maintenance on page 6-4
for more information.
Remember, you must reset the OIL LIFE display
yourself after each oil change. It will not reset itself.
Also, be careful not to reset the OIL LIFE display
accidentally at any time other than when the oil has
just been changed. It cannot be reset accurately until
the next oil change. To reset the engine oil life system,
seeEngine Oil Life System on page 5-18.

display, press and hold the trip odometer reset stem
to select between ON or OFF. If you choose ON,
the system will be turned on. If you choose OFF,
the system will be turned off. The URPA system
automatically turns back on after each vehicle start.

system serviced by your dealer/retailer if you notice
a drop in heating and air conditioning efficiency.
3-71

SERVICE AIR BAG
This message displays if there is a problem with the
airbag system. Have your dealer/retailer inspect

steer the vehicle increases or feels heavier, but you
will still be able to steer the vehicle. Have your vehicle
serviced by your dealer/retailer immediately.
3-72

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 5-88
for more information.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Variable Effort Steering
If your vehicle has this steering system, the system
continuously adjusts the effort you feel when steering at
all vehicle speeds. It provides ease when parking,
yet a rm, solid feel at highway speeds.
Steering Tips
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here is why:
Experienced driver or beginner, each of us is subject to
the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when
you turn the front wheels. If there is no traction, inertia
will keep the vehicle going in the same direction. If
you have ever tried to steer a vehicle on wet ice, you
will understand this.
The traction you can get in a curve depends on the
condition of the tires and the road surface, the angle at
which the curve is banked, and your speed. While
you are in a curve, speed is the one factor you
can control.
Suppose you are steering through a sharp curve.
Then you suddenly accelerate. Both control
systems — steering and acceleration — have to do their
work where the tires meet the road. Adding the
sudden acceleration can demand too much of those
places. You can lose control. SeeStabiliTrak
®System
on page 4-6.
What should you do if this ever happens? Ease up on
the accelerator pedal, steer the vehicle the way you
want it to go, and slow down.
