2009 GMC ACADIA parking brake

Notice:Ignoring these steps
could result in costly damage to
your vehicle that would not
be covered by your warranty.
Trying to start your vehicle
by pushing or pulling it will
not work, and it could damage
your vehicle.
1. Check the other vehicle. It must
have a 12-volt battery with a
negative ground system.
Notice:If the other vehicle’s
system is not a 12-volt system
with a negative ground, both
vehicles can be damaged. Only
use vehicles with 12-volt systems
with negative grounds to jump
start your vehicle.2. Get the vehicles close enough so
the jumper cables can reach, but
be sure the vehicles are not
touching each other. If they are, it
could cause a ground connection
you do not want. You would not
be able to start your vehicle, and
the bad grounding could damage
the electrical systems.
To avoid the possibility of the
vehicles rolling, set the parking
brake rmly on both vehicles
involved in the jump start
procedure. Put an automatic
transmission in P (Park) or a
manual transmission in Neutral
before setting the parking brake.
If one of the vehicles is a
four-wheel-drive vehicle, be sure
the transfer case is not in Neutral.Notice:If you leave the radio
or other accessories on during
the jump starting procedure,
they could be damaged. The
repairs would not be covered
by the warranty. Always turn off
the radio and other accessories
when jump starting the vehicle.
3. Turn off the ignition on both
vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter or the accessory
power outlets. Turn off the radio
and all lamps that are not needed.
This will avoid sparks and help
save both batteries. And it could
save the radio!

TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identication code. Any time
you rotate your vehicle’s tires or
replace one or more of the TPMS
sensors, the identication codes will
need to be matched to the new
tire/wheel position. The sensors are
matched to the tire/wheel positions
in the following order: driver side
front tire, passenger side front tire,
passenger side rear tire, and
driver side rear tire using a TPMS
diagnostic tool. See your dealer/
retailer for service.
The TPMS sensors can also be
matched to each tire/wheel position
by increasing or decreasing the
tire’s air pressure. If increasing the
tire’s air pressure, do not exceed
the maximum ination pressure
indicated on the tire’s sidewall.
To decrease air-pressure out of a
tire you can use the pointed end of
the valve cap, a pencil-style air
pressure gage, or a key.You have two minutes to match
the rst tire/wheel position, and
ve minutes overall to match
all four tire/wheel positions. If it
takes longer than two minutes, to
match the rst tire and wheel, or
more than ve minutes to match all
four tire and wheel positions the
matching process stops and you
need to start over.
The TPMS sensor matching process
is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to
ON/RUN with the engine off.
3. Press the Remote Keyless
Entry (RKE) transmitter’s LOCK
and UNLOCK buttons at the
same time for approximately
ve seconds. The horn sounds
twice to signal the receiver
is in relearn mode and TIRE
LEARNING ACTIVE message
displays on the DIC screen.
4. Start with the driver side front tire.5. Remove the valve cap from the
valve cap stem. Activate the
TPMS sensor by increasing or
decreasing the tire’s air pressure
for ve seconds, or until a horn
chirp sounds. The horn chirp,
which may take up to 30 seconds
to sound, conrms that the sensor
identication code has been
matched to this tire and wheel
position.
6. Proceed to the passenger
side front tire, and repeat
the procedure in Step 5.
7. Proceed to the passenger
side rear tire, and repeat
the procedure in Step 5.
8. Proceed to the driver side rear
tire, and repeat the procedure in
Step 5. The horn sounds two
times to indicate the sensor
identication code has been
matched to the driver side rear
tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARNING
ACTIVE message on the DIC
display screen goes off.

If a Tire Goes Flat
It is unusual for a tire to blowout
while you are driving, especially
if you maintain the tires properly.
SeeTires on page 5-35.Ifair
goes out of a tire, It is much more
likely to leak out slowly. But if
you should ever have a blowout,
here are a few tips about what
to expect and what to do:
If a front tire fails, the at tire will
create a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the
steering wheel rmly. Steer to
maintain lane position, and then
gently brake to a stop well out of
the traffic lane.
A rear blowout, particularly on a
curve, acts much like a skid and may
require the same correction youwould use in a skid. In any rear
blowout, remove your foot from the
accelerator pedal. Get the vehicle
under control by steering the way
you want the vehicle to go. It may be
very bumpy and noisy, but you can
still steer. Gently brake to a stop, well
off the road if possible.
If a tire goes at, avoid further tire
and wheel damage by driving slowly
to a level place and stopping.
1. Turn on the hazard warning
ashers. SeeHazard Warning
Flashers on page 3-5.
2. Park the vehicle. Set the parking
brake rmly and put the shift
lever in P (Park).
3. Turn off the engine.
4. Inspect the at tire.{CAUTION
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the appropriate
safety equipment and training. If a
jack is provided with the vehicle, it
is designed only for changing a
at tire. If it is used for anything
else, you or others could be badly
injured or killed if the vehicle slips
off the jack. If a jack is provided
with the vehicle, only use it for
changing a at tire.
This vehicle may come with a jack
and spare tire or a tire sealant
and compressor kit. To use the jack
and spare tire, seeChanging a
Flat Tire on page 5-69. To use the
tire sealant and compressor kit,
seeTire Sealant and Compressor
Kit on page 5-56.
Service and Appearance Care 5-55

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.
Removing the Spare Tire
and Tools
The tools needed to remove the
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.

Maintenance Footnotes
(a)
Visually inspect brake lines and
hoses for proper hook-up, binding,
leaks, cracks, chafing, etc. Inspect
disc brake pads for wear and rotors
for surface condition. Inspect other
brake parts, including calipers,
parking brake, etc. Check parking
brake adjustment.
(b) Visually inspect front and rear
suspension and steering system for
damaged, loose, or missing parts or
signs of wear. Inspect power steering
lines and hoses for proper hook-up,
