11-10 Service and Maintenance
Hoses
Hoses transport fluids and should
be regularly inspected to ensure
that there are no cracks or leaks.
With a multi-point inspection, your
dealer can inspect the hoses and
advise if replacement is needed.
Lamps
Properly working headlamps,
taillamps, and brake lamps are
important to see and be seen on
the road.
.Signs that the headlamps need
attention include dimming, failure
to light, cracking, or damage.
The brake lamps need to be
checked periodically to ensure
that they light when braking.
.With a multi-point inspection,
your dealer can check the lamps
and note any concerns.Shocks and Struts
Shocks and struts help aid in control
for a smoother ride.
.Signs of wear may include
steering wheel vibration, bounce/
sway while braking, longer

Warranty service can generally be
completed while you wait. However,
if you are unable to wait, GM helps
to minimize inconvenience by
providing several transportation
options. Depending on the
circumstances, your dealer can offer
one of the following:

warranty repairs, and public

your dealer's shuttle service, the
expense must be supported byoriginal receipts and can only be up
to the maximum amount allowed by

for U.S. customers, should you
arrange transportation through a
friend or relative, limited
reimbursement for reasonable fuel
expenses may be available. Claim
amounts should reflect actual costs
and be supported by original
receipts. See your dealer for
information regarding the allowance
amounts for reimbursement of fuel
or other transportation costs.

Your dealer may arrange to provide
you with a courtesy rental vehicle or
reimburse you for a rental vehicle
that you obtain if the vehicle is kept
for an overnight warranty repair.
Rental reimbursement will be limited
and must be supported by original
receipts. This requires that you sign
and complete a rental agreement
and meet state/provincial, local, and
rental vehicle provider requirements.
Requirements vary and may include
minimum age requirements,insurance coverage, credit card, etc.

charges and may also be

fees, excessive mileage, or rental
usage beyond the completion of the

like vehicle as a courtesy rental.

Vehicle Data
Recording and
Privacy
The vehicle has a number of
computers that record information
about the vehicle’s performance and
how it is driven. For example, the
vehicle uses computer modules to
monitor and control engine and
transmission performance, to
monitor the conditions for airbag
deployment and deploy them in a
crash, and, if equipped, to provide
antilock braking to help the driver
control the vehicle. These modules
may store data to help the dealer
technician service the vehicle.
Some modules may also store data
about how the vehicle is operated,
such as rate of fuel consumption or
average speed. These modules may
retain personal preferences, such as
radio presets, seat positions, and
temperature settings.
