Headlamp Aiming
Front Headlamp Aiming
Headlamp aim has been preset and should
need no further adjustment.
If the vehicle is damaged in a crash, the
headlamp aim may be affected.
If adjustment to the headlamps is necessary,
see your dealer.
Bulb Replacement
Switch off the ignition and switch off the
relevant switch or close the doors. Only hold
a new bulb at the base! Do not touch the
bulb glass with bare hands.
For any bulb-changing procedure not listed
in this section, contact your dealer.
After driving in heavy rain or washing, some
exterior lamp lenses could appear frosty.
This condition is caused by the temperature
difference between the lamp inside and
outside. This is similar to the condensation
on your windows inside your vehicle during
the rain and doesn't indicate a problem with
your vehicle.
If the water leaks into the light bulb
circuitry, have the vehicle checked, we
recommend an authorized repairer.
Caution
Do not replace incandescent bulbs with
aftermarket LED replacement bulbs. This
can cause damage to the vehicle electrical
system.

tightened. See
“Wheel Nut Torque”
under Capacities and Specifications
0 329, and “Removing the Flat Tire and
Installing the Spare Tire” underTire
Changing 0297.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose after
time. The wheel could come off and
cause a crash. When changing a
wheel, remove any rust or dirt from
places where the wheel attaches to
the vehicle. In an emergency, a cloth
or a paper towel can be used;
however, use a scraper or wire brush
later to remove all rust or dirt.
Lightly coat the inner diameter of the
wheel hub opening with wheel bearing
grease after a wheel change or tire
rotation to prevent corrosion or rust
build-up.
{Warning
Do not apply grease to the wheel
mounting surface, wheel conical
seats, or the wheel nuts or bolts.
Grease applied to these areas could
cause a wheel to become loose or
come off, resulting in a crash.
When It Is Time for New Tires
Factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road
conditions affect the wear rate of the tires.
Treadwear indicators are one way to tell
when it is time for new tires. Treadwear
indicators appear when the tires have only

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 or used.
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 or to help GM improve
safety or features. 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.
