2009 GMC ACADIA park assist

Before Leaving on a
Long Trip
To prepare your vehicle for a long
trip, consider having it serviced
by your dealer/retailer before
departing.
Things to check on your own
include:
Windshield Washer Fluid:
Reservoir full? Windows
clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All
levels checked?
Lamps:Do they all work and are
lenses clean?
Tires:Are treads good? Are tires
inated to recommended
pressure?
Weather and Maps:Safe to
travel? Have up-to-date maps?
Highway Hypnosis
Always be alert and pay attention
to your surroundings while driving.
If you become tired or sleepy,
nd a safe place to park your
vehicle and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.
Keep your eyes moving — scan
the road ahead and to the sides.
Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on at or rolling terrain. Tips for
driving in these conditions include:
Keep the vehicle serviced
and in good shape.
Check all uid levels and brakes,
tires, cooling system, and
transmission.
Going down steep or long hills,
shift to a lower gear.
{CAUTION
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.

Tow/Haul Mode
Tow/Haul is a feature that assists
when pulling a heavy trailer or
a large or heavy load. The purpose
of the Tow/Haul mode is to:
Reduce the frequency and
improve the predictability of
transmission shifts when pulling
a heavy trailer or a large or
heavy load.
Provide the same solid shift feel
when pulling a heavy trailer or a
large or heavy load as when
the vehicle is unloaded.
Improve control of vehicle speed
while requiring less throttle pedal
activity when pulling a heavy
trailer or a large or heavy load.
Increase the charging system
voltage to assist in recharging
a battery installed in a trailer.Press this button located on the
console to turn on and turn off the
Tow/Haul mode.
The Tow/Haul light on the
instrument panel will come on to
indicate that Tow/Haul mode
has been selected.
Tow/Haul may be turned off by
pressing the button again, at which
time the indicator light on the
instrument panel will turn off. The
vehicle will automatically turn
off Tow/Haul every time it is started.
Tow/Haul is designed to be most
effective when the vehicle and
trailer combined weight is at
least 75 percent of the vehicle’s
Gross Combined Weight Rating
(GCWR). See Weight of the Trailerearlier in this section. Tow/Haul is
most useful under the following
driving conditions:
When pulling a heavy trailer or a
large or heavy load through
rolling terrain.
When pulling a heavy trailer or a
large or heavy load in stop and
go traffic.
When pulling a heavy trailer or a
large or heavy load in busy
parking lots where improved low
speed control of the vehicle is
desired.
Operating the vehicle in Tow/Haul
when lightly loaded or with no trailer
at all will not cause damage.
However, there is no benet to the
selection of Tow/Haul when the
vehicle is unloaded. Such a selection
when unloaded may result in
unpleasant engine and transmission
driving characteristics and reduced
fuel economy. Tow/Haul is
recommended only when pulling a
heavy trailer or a large or heavy load.

9. If the coolant level inside the
radiator ller neck is low, add
more of the proper DEX-COOL
coolant mixture through the
ller neck until the level is back
up to the base of the ller
neck. Replace the pressure cap.
Be sure to secure it tightly.
Notice:If the pressure cap is
not tightly installed, coolant loss
and possible engine damage
may occur. Be sure the cap is
properly and tightly secured.
Engine Overheating
The vehicle has several indicators
to warn of engine overheating.
There is an engine coolant
temperature gage on the instrument
panel cluster. SeeEngine Coolant
Temperature Gage on page 3-40.The vehicle may also display
an ENGINE OVERHEATED
IDLE ENGINE and ENGINE
OVERHEATED STOP ENGINE
message in the Driver Information
Center (DIC). SeeDIC Warnings
and Messages on page 3-56.
You may decide not to lift the hood
when this warning appears, but
instead get service help right away.
SeeRoadside Assistance Program
on page 7-6.
If you do decide to lift the hood,
make sure the vehicle is parked
on a level surface
Then check to see if the engine
cooling fans are running. If the
engine is overheating, both fans
should be running. If they are
not, do not continue to run the
engine and have the vehicle
serviced.Notice:Engine damage from
running the engine without
coolant is not covered by the
warranty.
Notice:If the engine catches re
while driving with no coolant, the
vehicle can be badly damaged.
The costly repairs would not be
covered by the vehicle warranty.
SeeOverheated Engine Protection
Operating Mode on page 5-23for
information on driving to a safe
place in an emergency.

Changing a Flat Tire
If a tire goes at, avoid further
tire and wheel damage by driving
slowly to a level place. Turn on
the hazard warning ashers.
SeeHazard Warning Flashers
on page 3-5.
{CAUTION
Changing a tire can be
dangerous. The vehicle can slip
off the jack and roll over or fall
on you or other people. You and
they could be badly injured or
even killed. Find a level place to
change your tire. To help prevent
the vehicle from moving:
1. Set the parking brake rmly.
2. Put the shift lever in
P (Park).
(Continued)
CAUTION (Continued)
3. Turn off the engine and do
not restart while the vehicle
is raised.
4. Do not allow passengers to
remain in the vehicle.
To be even more certain the
vehicle will not move, you should
put blocks at the front and rear of
the tire farthest away from the
one being changed. That would
be the tire, on the other side, at
the opposite end of the vehicle.
When the vehicle has a at tire (B),
use the following example as a
guide to assist you in the placement
of wheel blocks (A).A. Wheel Block
B. Flat Tire
The following information explains
how to use the jack and change
a tire.

spare tire are located in the storage
compartment on the driver side,
at the rear of the vehicle.
1. Open the jack storage
compartment by pulling on
the latch tab, located toward
the rear of the vehicle, and
pulling the cover off.
