2010 BUICK LACROSSE airbag

8-60 Driving and Operating
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the
safety chains under the tongue of
the trailer to help prevent the tongue
from contacting the road if it
becomes separated from the hitch.
Leave enough slack so the rig can
turn. Never allow safety chains to
drag on the ground.
Trailer Brakes
Does the trailer have its own
brakes? Be sure to read and follow
the instructions for the trailer brakes
so they are installed, adjusted and
maintained properly.
Because the vehicle has antilock
brakes, do not tap into the vehicle's
brake system. If this is done, both
brake systems will not work well,
or at all.
Conversions and
Add-Ons
Add-On Electrical
Equipment
Notice:Do not add anything
electrical to the vehicle unless
you check with your dealer/
retailer first. Some electrical
equipment can damage the
vehicle and the damage would
not be covered by the vehicle's
warranty. Some add-on electrical
equipment can keep other
components from working as
they should.
Add-on equipment can drain the
vehicle battery, even if the vehicle is
not operating.
The vehicle has an airbag system.
Before attempting to add anything
electrical to the vehicle, see
Servicing the Airbag-Equipped
Vehicle
on page 2‑37and Adding
Equipment to the Airbag-Equipped
Vehicle on page 2‑38.

California Perchlorate
Materials Requirements
Certain types of automotive
applications, such as airbag
initiators, seat belt pretensioners,
and lithium batteries contained in
remote keyless transmitters, may
contain perchlorate materials.
Special handling may be necessary.
For additional information, see
www.dtsc.ca.gov/hazardouswaste/
perchlorate.
Accessories and
Modifications
Adding non-dealer/non-retailer
accessories to the vehicle can affect
vehicle performance and safety,
including such things as airbags,
braking, stability, ride and handling,
emissions systems, aerodynamics,
durability, and electronic systems
like antilock brakes, traction control,
and stability control. Some of these
accessories could even cause
malfunction or damage not covered
by the vehicle warranty.
Damage to vehicle components
resulting from the installation or use
of non-GM certified parts, including
control module modifications, are
not covered under the terms of the
vehicle warranty and may affect
remaining warranty coverage for
affected parts.GM Accessories are designed to
complement and function with other
systems on the vehicle. Your GM
dealer/retailer can accessorize the
vehicle using genuine GM
Accessories. When you go to your
GM dealer/retailer and ask for GM
Accessories, you will know that
GM-trained and supported service
technicians will perform the work
using genuine GM Accessories.

Doing Your Own
Service Work
{WARNING
You can be injured and the
vehicle could be damaged if you
try to do service work on a vehicle
without knowing enough about it.
.Be sure you have
sufficient knowledge,
experience, the proper
replacement parts, and tools
before attempting any vehicle
maintenance task.(Continued)
WARNING (Continued)
.Be sure to use the proper
nuts, bolts, and other
fasteners. English and metric
fasteners can be easily
confused. If the wrong
fasteners are used, parts can
later break or fall off. You
could be hurt.
If doing some of your own service
work, use the proper service
manual. It tells you much more
about how to service the vehicle
than this manual can. To order the
proper service manual, see Service
Publications Ordering Information
on
page 12‑12. This vehicle has an airbag system.
Before attempting to do your own
service work, see
Airbag System
Check on page 2‑39.
Keep a record with all parts receipts
and list the mileage and the date of
any service work performed. See
Maintenance Records
on
page 10‑10.

Vehicle Care 9-63
Vehicles that have a tire
pressure monitoring system
could give an inaccurate
low-pressure warning if non-TPC
Spec rated tires are installed on
your vehicle. Non-TPC Spec
rated tires may give a
low-pressure warning that is
higher or lower than the proper
warning level you would get with
TPC Spec rated tires. SeeTire
Pressure Monitor System
on
page 9‑54
.
Your vehicle's original
equipment tires are listed on the
Tire and Loading Information
Label. See Vehicle Load Limits
on page 8‑12, for more
information about the Tire and
Loading Information Label and
its location on your vehicle.
Different Size Tires and
Wheels
If you add wheels or tires that are a
different size than your original
equipment wheels and tires, this
could 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, rollover airbags, traction
control, and electronic stability
control, the performance of these
systems can be affected.
{WARNING
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
specific wheel and tire systems
developed for your vehicle, and
have them properly installed by a
GM certified technician.
See Buying New Tires
on
page 9‑61and Accessories and
Modificationson page 9‑3for
additional information.

Customer Information 12-11
any vehicle failure related to such
parts are not covered by that
warranty.
Repair Facility
We recommend that you choose a
collision repair facility that meets
your needs before you ever need
collision repairs. Your dealer/retailer
may have a collision repair center
with GM-trained technicians and
state of the art equipment, or be
able to recommend a collision repair
center that has GM-trained
technicians and comparable
equipment.
Insuring Your Vehicle
Protect your investment in your GM
vehicle with comprehensive and
collision insurance coverage. There
are significant differences in the
quality of coverage afforded by
various insurance policy terms.
Many insurance policies provide
reduced protection to your GM
vehicle by limiting compensation for
damage repairs by usingaftermarket collision parts. Some
insurance companies will not
specify aftermarket collision parts.
When purchasing insurance, we
recommend that you assure your
vehicle will be repaired with GM
original equipment collision parts.
If such insurance coverage is not
available from your current
insurance carrier, consider switching
to another insurance carrier.
If your vehicle is leased, the leasing
company may require you to have
insurance that assures repairs with
Genuine GM Original Equipment
Manufacturer (OEM) parts or
Genuine Manufacturer replacement
parts. Read your lease carefully, as
you may be charged at the end of
your lease for poor quality repairs.
If a Crash Occurs
If there has been an injury, call
emergency services for help. Do not
leave the scene of a crash until all
matters have been taken care of.
Move the vehicle only if its position
puts you in danger, or you are
instructed to move it by a police
officer.
Give only the necessary information
to police and other parties involved
in the crash.
For emergency towing see

Gather the following information:
.Driver's name, address, phone
number
.Driver's license number
.Owner's name, address, phone
number
.Vehicle license plate
.Vehicle make, model and
model year
.Vehicle Identification
Number (VIN)
.Insurance company and policy
number
.General description of the
damage to the other vehicle

12-12 Customer Information
Choose a reputable repair facility
that uses quality replacement parts.

section.

Will You See After an Airbag
Inflates? on page 2‑30.
Managing the Vehicle Damage
Repair Process
In the event that your vehicle
requires damage repairs, GM
recommends that you take an active
role in its repair. If you have a
pre-determined repair facility of
choice, take your vehicle there,
or have it towed there. Specify to
the facility that any required
replacement collision parts be
original equipment parts, either new
Genuine GM parts or recycled
original GM parts. Remember,
recycled parts will not be covered by
your GM vehicle warranty. Insurance pays the bill for the repair,
but you must live with the repair.
Depending on your policy limits,
your insurance company may
initially value the repair using
aftermarket parts. Discuss this with
your repair professional, and insist
on Genuine GM parts. Remember if
your vehicle is leased you may be
obligated to have the vehicle
repaired with Genuine GM parts,
even if your insurance coverage
does not pay the full cost.
If another party's insurance
company is paying for the repairs,
you are not obligated to accept a
repair valuation based on that
insurance company's collision policy
repair limits, as you have no
contractual limits with that company.
In such cases, you can have control
of the repair and parts choices as
long as cost stays within reasonable
limits.
