2007 BUICK LACROSSE lock

To disconnect the jumper cables from both
vehicles, do the following:
1. Disconnect the black negative (−) cable from
the vehicle that had the dead battery.
2. Disconnect the black negative (−) cable from
the vehicle with the good battery.
3. Disconnect the red positive (+) cable from the
vehicle with the good battery.
4. Disconnect the red positive (+) cable from the
other vehicle.
5. Return the fuse block cover to its original
position.
Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim has been preset at the factory
and should need no further adjustment
However, If the vehicle is damaged in an accident,
the headlamp aim may be affected and adjustment
may be necessary.
If oncoming vehicles ash their high beams at
you, this may also mean the vertical aim needs to
be adjusted.It is recommended that the vehicle is taken to your
dealer for service if the headlamps need to be
re-aimed. It is possible however, to re-aim
the headlamps as described in the following
procedure.
The vehicle should be properly prepared as follows:
The vehicle should be placed so the headlamps
are 25 ft. (7.6 m) from a light colored wall.
The vehicle must have all four tires on a
perfectly level surface which is level all the way
to the wall.
The vehicle should be placed so it is
perpendicular to the wall.
The vehicle should not have any snow, ice or
mud on it.
The vehicle should be fully assembled and all
other work stopped while headlamp aiming is
being done.
The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs
(75 kg) on the driver’s seat.
Tires should be properly inated.

4. At the wall measure from the ground
upward (A) to the recorded distance
from Step 3 and mark it.
Notice:Do not cover a headlamp to improve
beam cut-off when aiming. Covering a
headlamp may cause excessive heat build-up
which may cause damage to the headlamp.
5. Draw or tape a horizontal line (B) on the wall
the width of the vehicle at the height of the
mark in Step 4.6. Turn on the low-beam headlamps and place a
piece of cardboard or equivalent in front of the
headlamp not being adjusted. Do not place
directly on the headlamp. This allows only the
beam of light from the headlamp being
adjusted to be seen on the at surface.
7. Locate the vertical headlamp aiming screws,
which are under the hood near each headlamp
assembly.
The adjustment screw can be turned with a
6 mm male hex.
8. Turn the vertical aiming screw until the
headlamp beam is aimed to the horizontal tape
line. Turn it clockwise or counterclockwise to
raise or lower the angle of the beam.

page 349for more information.
2. Locate the high-beam headlamp bulb socket.
3. Remove the access cover from behind the
bulb being replaced.
4. Turn the bulb socket counterclockwise and
pull it from the headlamp assembly.
5. Holding the base of the socket, pull the old
bulb from the socket.
6. Replace with a new bulb.
7. Reverse Steps 2 through 4 to reinstall.
Front Turn Signal and Parking
Lamps
To replace a front turn signal/parking lamp bulb in
the front fascia, do the following:
1. Locate the front turn signal/parking bulb
socket by reaching behind the front bumper.
2. Turn the bulb socket counterclockwise and
pull it out of the assembly.
3. Holding the base of the socket, pull the old
bulb from the socket.
4. Push the new bulb into the socket.

License Plate Lamp
To replace one of these bulbs, do the following:
1. Remove the two screws holding each of
the license plate lamps to the fascia.
2. Turn and pull the license plate lamp forward
through the fascia opening.

TPMS Sensor Identication Codes
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
for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. When increasing the tire’s
pressure, do not exceed the maximum ination
pressure indicated on the tire’s sidewall.
You have two minutes to match each tire and
wheel position. If it takes longer than two minutes
to match any tire and wheel position, the
matching process stops and you need to
start over.The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to 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 the
TPMS sensor matching process can begin.
4. Start with the driver side front tire.
5. Remove the valve cap from the tire’s valve
stem. Activate the TPMS sensor by increasing
or decreasing the tire’s air pressure for
10 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 the
tire/wheel position. To decrease the tire’s
air-pressure use the pointed end of the valve
cap, a pencil-style air pressure gage, or a key.

Different Size Tires and Wheels
If you add wheels or tires that are a different
size than your original equipment wheels and
tires, this may affect the way your vehicle
performs, including its braking, ride and handling
characteristics, stability, and resistance to
rollover. Additionally, if your vehicle has electronic
systems such as, anti-lock brakes, traction
control, and electronic stability control, the
performance of these systems can be affected.{CAUTION:
If you add different sized wheels, your
vehicle may not provide an acceptable
level of performance and safety if tires
not recommended for those wheels are
selected. You may increase the chance
that you will crash and suffer serious
injury. Only use GM specic wheel and
tire systems developed for your vehicle,
and have them properly installed by a
GM certied technician.
SeeBuying New Tires on page 418and
Accessories and Modications on page 341for
additional information.

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 vehicle’s hazard warning ashers. SeeHazard
Warning Flashers on page 150for more
information.
{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 PARK (P).
CAUTION: (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 your vehicle has a at tire, use the following
example as a guide to assist you in the placement
of wheel blocks.
