If your vehicle has this option, it has a theft-deterrent
alarm system. Once armed, the system will sound the
horn and flash the parking lamps if the vehicle is
broken into.
Shock Sensor
Coupe Convertible
The shock sensor is what triggers the alarm when it
detects a blow to your vehicle. It
is located over the
right rear wheelhouse near the spare
tire in the hatch
area. There are two levels of alarms via the shock
sensor: Two horn blasts and parking lamp flashes for
non-threatening blows to the vehicle and
a full two
minute alarm for harder blows to the vehicle. Its
sensitivity can be adjusted if more or less sensitivity is
desired. (Note: If sensitivity is increased too much,
it
may give false alarms caused by gusts of wind or other
natural events that may shake the vehicle).
To adjust, remove the label covering the adjustment
knob on the sensor and adjust as desired. Turn clockwise
to increase sensitivity and turn counterclockwise to decrease sensitivity. The shock sensor
is ignored by the
alarm system when the ignition is on, when the hatch is
open, when the alarm is disarmed, when it is customized
to be ignored and for five seconds after
the horn sounds
an alarm or chirp. The shock sensor is ignored after
triggering three full alarms until the system is rearmed.

LOW
TRAC
This light will come on
when your traction control
system is limiting wheel
spin. See “Low Traction
Light” in the Index.
You
may feel or hear the system
working, but this is normal.
TCS
OFF
When the system is on,
this warning light will
come on to let you how
if
there’s a problem with your
traction control. system.
See “Traction Control
System Warning Light”
in the Index.
The traction control system may operate on dry roads
under some conditions, and you may notice a reduction
in acceleration when this happens. This is normal and
doesn’t mean there’s a problem with your vehicle.
Examples of these conditions include a hard acceleration
in
a turn, or an abrupt upshift or downshift. Also, when
the compact spare tire is on
the rear axle, the traction
control system will cycle and limit acceleration for about
the first 15 seconds of driving after each engine start.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
re-engage the cruise control. (See “Cruise Control’’ in
the Index.)
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle.
To limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off
if you ever need to. (You
should turn the system off if your vehicle ever gets stuck
in sand, mud,
ice or snow. See “Rocking Your Vehicle”
in the Index.)

On convertible models, you must also remove the
convertible top protection panel. It’s
at the upper back of
the trunk. Turn the two screw knobs under the trunk
edge
a quarter turn left (counterclockwise) to remove
the panel.

rear area behind the trim panel.
First you must remove the close-out panel. See

jack under the vehicle. There
is a notch
in the vehicle’s rocker flange
on the coupe model.
Raise the jack head until
it fits firmly into the notch
nearest the flat tire.
On convertible models, place
the jack in a
similar location.

to replace them, be sure to get new
GM original
equipment wheel nuts.
Stop somewhere as
soon as you can and have the
1 nuts tightened with a torque wrench to 100 lb-ft
(140 N.m).

brake pulsation and rotor damage.
To avoid
expensive brake repairs, evenly tighten the
wheel
nuts in the proper sequence and to the proper
torque specification.
