2009 BUICK LACROSSE spare tire location

The vehicle should be:
Placed so the headlamps are 25 ft. (7.6 m) from a
light colored wall.
On a perfectly level surface which is level all the
way to the wall.
Be placed so it is at a right angle to the wall.
Clear of any snow, ice or mud on it.
Be fully assembled, with the tires properly inated
and all other work stopped while headlamp aiming
is being done.
Be normally loaded with a full tank of fuel, with the
spare tire in its proper location, and one person or
160 lbs (75 kg) on the driver seat.
Headlamp aiming is done with the vehicle’s low-beam
headlamps. The high-beam headlamps will be correctly
aimed if the low-beam headlamps are aimed properly.
Locate the vertical headlamp aiming screws under
the hood near the headlamps.The adjustment screw can be turned with a 6 mm
male hex.

Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor System
(TPMS). The TPMS is designed to warn the driver when
a low tire pressure condition exists. TPMS sensors are
mounted onto each tire and wheel assembly, excluding
the spare tire and wheel assembly. The TPMS sensors
monitor the air pressure in the vehicle’s tires and
transmits the tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure
condition is detected, the
TPMS illuminates the low
tire pressure warning light
located on the instrument
panel cluster.
If your vehicle has the uplevel Driver Information
Center (DIC), a warning message to check the pressure
in a specic tire displays at the same time the low tire
pressure warning light comes on. The low tire pressure
warning light and the DIC warning message come on at
each ignition cycle until the tires are inated to the correct
ination pressure. Vehicles that have the uplevel DICbuttons can also check tire pressure levels by pressing
the gages button. For additional information and details
about the DIC operation and displays seeDIC Operation
and Displays on page 3-48andDIC Warnings and
Messages on page 3-56
The low tire pressure warning light may come on in
cool weather when the vehicle is rst started, and then
turn off as you start to drive. This could be an early
indicator that the air pressure in the tire(s) are getting
low and need to be inated to the proper pressure.
A Tire and Loading Information label, attached to
your vehicle, shows the size of your vehicle’s original
equipment tires and the correct ination pressure for
your vehicle’s tires when they are cold. SeeLoading the
Vehicle on page 4-20, for an example of the Tire and
Loading Information label and its location on your vehicle.
Also seeInflation - Tire Pressure on page 5-61.
Your vehicle’s TPMS system can warn you about a low
tire pressure condition but it does not replace normal
tire maintenance. SeeTire Inspection and Rotation
on page 5-67andTires on page 5-54.
Notice:Liquid tire sealants could damage the Tire
Pressure Monitor System (TPMS) sensors. Sensor
damage caused by using a tire sealant is not covered
by your warranty. Do not use liquid tire sealants.

You need new tires if any of the following statements
are true:
You can see the indicators at three or more places
around the tire.
You can see cord or fabric showing through the
tire’s rubber.
The tread or sidewall is cracked, cut, or snagged
deep enough to show cord or fabric.
The tire has a bump, bulge, or split.
The tire has a puncture, cut, or other damage that
cannot be repaired well because of the size or
location of the damage.
The rubber in tires degrades over time, even if they are
not being used. This is also true for the spare tire, if your
vehicle has one. Multiple conditions affect how fast this
aging takes place, including temperatures, loading
conditions, and ination pressure maintenance. With
proper care and maintenance tires will typically wear out
before they degrade due to age. If you are unsure about
the need to replace your tires as they get older, consult
the tire manufacturer for more information.
Buying New Tires
GM has developed and matched specic tires for
your vehicle. The original equipment tires installed
on your vehicle, when it was new, were designed
to meet General Motors Tire Performance Criteria
Specication (TPC Spec) system rating. If you need
replacement tires, GM strongly recommends that
you get tires with the same TPC Spec rating. This
way, your vehicle will continue to have tires that are
designed to give the same performance and vehicle
safety, during normal use, as the original tires.
GM’s exclusive TPC Spec system considers
over a dozen critical specications that impact the
overall performance of your vehicle, including brake
system performance, ride and handling, traction
control, and tire pressure monitoring performance.
GM’s TPC Spec number is molded onto the tire’s
sidewall near the tire size. If the tires have an
all-season tread design, the TPC Spec number
will be followed by an MS for mud and snow. See
Tire Sidewall Labeling on page 5-55for additional
information.

{CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
{CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even make
the vehicle fall. To help avoid personal injury and
vehicle damage, be sure to t the jack lift head into
the proper location before raising the vehicle.
4. Put the compact spare tire near you.5. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle far enough off the
ground for the compact spare tire to t under the
vehicle.
6. Remove all wheel nuts and take off the at tire.

Storing a Flat or Spare Tire and
Tools (Base Model)
{CAUTION:
Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or collision, loose
equipment could strike someone. Store all these
in the proper place.
After the compact spare tire has been installed on the
vehicle, store the at tire in the trunk.
When storing a full-size tire, use the extension with
the extension protector, located in the foam holder,
to help avoid wheel surface damage.To store a full-size tire:
1. Install the tools in their original location in the trunk
area and secure.
2. Place the tire valve stem facing down and the
protector/guide placed through a wheel bolt hole.
3. Remove the protector and attach the retainer
securely.
4. Store the cover as far forward as possible.
When storing a compact spare tire in the trunk, put the
protector back in the foam holder.
The compact spare is for temporary use only. Replace
the compact spare tire with a full-size tire as soon as you
can. SeeCompact Spare Tire on page 5-89. Use this as
a guide for storing the compact spare tire and tools.
