2009 HUMMER H3 parking brake

Jump Starting
If the vehicle’s battery has run
down, you may want to use another
vehicle and some jumper cables
to start your vehicle. Be sure to use
the following steps to do it safely.
{CAUTION
Batteries can hurt you. They can
be dangerous because:
They contain acid that can
burn you.
They contain gas that can
explode or ignite.
They contain enough
electricity to burn you.
If you do not follow these steps
exactly, some or all of these
things can hurt you.Notice:Ignoring these steps
could result in costly damage to
the vehicle that would not be
covered by the warranty.
Trying to start the vehicle by
pushing or pulling it will not work,
and it could damage the 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 you have a
four-wheel-drive vehicle,
be sure the transfer case is
not in Neutral.

TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identication code. Any time
you replace one or more of the
TPMS sensors or rotate the
vehicle’s tires, the identication
codes 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 let 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 one minute to match
the rst tire/wheel position,
and ve minutes overall, to match
all four tire/wheel positions. If it
takes longer than one minute, 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
procedure is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to
ON/RUN with the engine off.
3. Turn the exterior lamp switch
from AUTO to OFF four times
within three seconds. A double
horn chirp will sound and
the TPMS low tire warning light
starts ashing. The double
horn chirp and ashing TPMS
warning light indicates the
TPMS matching process has
started. The TPMS warning
light should continue ashingthroughout the matching
procedure. The LOW TIRE
message displays on the Driver
Information Center (DIC).
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 10 seconds, then stop and
listen for a single horn chirp.
The single horn chirp should
sound within 15 seconds,
conrming that the sensor
identication code has been
matched to this tire and wheel
position. If you do not hear
the conrming single horn chirp,
turn the ignition switch to
LOCK and start over beginning
with Step 2.
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.
5-56 Service and Appearance Care

If a Tire Goes Flat
It is unusual for a tire to blowout
while you are driving, especially if
you maintain your vehicle’s tires
properly. If air 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
creates 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 you
would 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.
{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.
If a tire goes at, the next part
shows how to use the jacking
equipment to change a at tire
safely.
Changing a Flat Tire
If a tire goes at, avoid further tire
and wheel damage by driving
slowly to a level place. Turn on
your 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).
