seats, safety belts, the airbag
sensing and diagnostic module,
steering wheel, instrument panel,
roof-rail airbag modules, ceiling
headliner or pillar garnish trim,
overhead console, front sensors,
side impact sensors, rollover
sensor module, or airbag wiring
can affect the operation of the
airbag system.
In addition, the vehicle has a
passenger sensing system for the
right front passenger position,
which includes sensors that are
part of the passenger seat.
The passenger sensing system
may not operate properly if the
original seat trim is replaced with
non-GM covers, upholstery or
trim, or with GM covers,
upholstery or trim designed for a
different vehicle. Any object, such
as an aftermarket seat heater or a
comfort enhancing pad or device,
installed under or on top of theseat fabric, could also interfere
with the operation of the
passenger sensing system.
This could either prevent proper
deployment of the passenger
airbag(s) or prevent the
passenger sensing system from
properly turning off the passenger
airbag(s). SeePassenger
Sensing System on page 1-54.

Features and Controls 2-51

Automatic Headlamp
System
When it is dark enough outside,
the automatic headlamp system
will turn on after the transmission
has been shifted from P (Park) to
D (Drive). The headlamps, taillamps,
sidemarker, parking lamps, roof
marker lamps, and the instrument
panel lights turn on at normal
brightness. The radio lights will
become dimmer when the
headlights are off compared to
when the headlights are on.
The vehicle has a light sensor
located on the top of the instrument
panel. Do not cover the sensor,
or the system will be on whenever
the ignition is on.
The system can turn on the
headlamps when driving in a parking
garage, through a tunnel or when
there is overcast weather. This
is normal.There is a delay in the transition
between the daytime and nighttime
operation of the Daytime Running
Lamps (DRL) and the automatic
headlamp system so that driving
under bridges or bright overhead
street lights does not affect the
system. The DRL and automatic
headlamp system will only be
affected when the light sensor
detects a change in lighting lasting
longer than the delay.
If the vehicle is started in a dark
garage, the automatic headlamp
system will come on immediately.
Once the vehicle leaves the garage,
it will take about one minute for
the automatic headlamp system to
change to DRL if it is light
outside. During that delay, the
instrument panel cluster may not be
as bright as usual. Make sure the
instrument panel brightness
control is in the full bright position.
SeeInstrument Panel Brightness on
page 3-15.
Off-Road Lamps
The off-road lamps, if the vehicle
has them, provide auxiliary lighting
when the vehicle is used off
road. These lamps are not intended
to be used in place of existing
vehicle lighting. The lamps are not
to be used on any public street
or highway and are to be covered
when not in use. Check your
state and local laws before installing
or using any auxiliary lighting. In
some states it may be necessary to
remove the roof lamps when
operating the vehicle on the
highway.
