service BUICK LACROSSE 2007 Owner's Manual

To read this information, special equipment is
needed and access to the vehicle or the device
that stores the data is required. GM will not access
information about a crash event or share it with
others other than:
with the consent of the vehicle owner or, if the
vehicle is leased, with the consent of the
lessee,
in response to an official request of police or
similar government office,
as part of GM’s defense of litigation through
the discovery process, or
as required by law.
In addition, once GM collects or receives data,
GM may:
use the data for GM research needs,
make it available for research where
appropriate condentiality is to be maintained
and need is shown, or
share summary data which is not tied to a
specic vehicle with non-GM organizations
for research purposes.Others, such as law enforcement, may have
access to the special equipment that can read the
information if they have access to the vehicle
or the device that stores the data.
If your vehicle has OnStar
®, please check the
OnStar®subscription service agreement or manual
for information on its operations and data collection.
Collision Damage Repair
If your vehicle is involved in a collision and it is
damaged, have the damage repaired by a qualied
technician using the proper equipment and quality
replacement parts. Poorly performed collision
repairs will diminish your vehicle’s resale value, and
safety performance can be compromised in
subsequent collisions.
Collision Parts
Genuine GM Collision parts are new parts made
with the same materials and construction methods
as the parts with which your vehicle was originally
built. Genuine GM Collision parts are your best
choice to assure that your vehicle’s designed
appearance, durability, and safety are preserved.
The use of Genuine GM parts can help maintain
your GM New Vehicle Warranty.

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 an Accident Occurs
Here is what to do if you are involved in an
accident.
Try to relax and then check to make sure you
are all right. If you are uninjured, make sure that
no one else in your vehicle, or the other vehicle,
is injured.
If there has been an injury, call 911 for help. Do
not leave the scene of an accident until all
matters have been taken care of. Move your
vehicle only if its position puts you in danger or
you are instructed to move it by a police officer.
Give only the necessary and requested
information to police and other parties involved
in the accident. Do not discuss your personal
condition, mental frame of mind, or anything
unrelated to the accident. This will help guard
against post-accident legal action.
If you need roadside assistance, call GM
Roadside Assistance. SeeRoadside
Assistance Program on page 484for more
information.
If your vehicle cannot be driven, know where
the towing service will be taking it. Get a card
from the tow truck operator or write down the
driver’s name, the service’s name, and the
phone number.
Remove any valuables from your vehicle before
it is towed away. Make sure this includes your
insurance information and registration if you
keep these items in your vehicle.
Gather the important information you will need
from the other driver. Things like name,
address, phone number, driver’s license
number, vehicle license plate, vehicle make,
model and model year, Vehicle Identication
Number (VIN), insurance company and policy
number, and a general description of the
damage to the other vehicle.
