appear in the DIC. Press up or
down on the PTM switch to
scroll through the options and
make a selection. To exit PTM,
select INACTIVE in the PTM
menu, turn off PTM in the
V-Mode configuration page,
or press the ESC switch once.
Selecting PTM states may

Launch Control
If equipped, Launch Control is

Driving Mode and PTM to
allow high levels of vehicle
acceleration in a straight line.
Launch Control is a form of
traction control that manages
tire spin while launching the
vehicle. This feature is
intended for use during closed
course race events where
consistent zero to
60 and quarter mile times are
desirable. Launch Control is only
available when the following
criteria are met:
.Competitive Driving Mode is
selected or any of the PTM
modes are selected. The
traction off light comes on in
the instrument cluster and
the appropriate DIC
message displays.
.The vehicle is not moving.
.The steering wheel is
pointing straight.
Automatic Transmissions
.The brake pedal is firmly
pressed to the floor,
equivalent to a panic brake
event.
.The accelerator pedal is
rapidly applied to wide open
throttle. If the vehicle rolls
due to wide open throttle,
release the throttle, press
the brake pedal more firmly,
and reapply the accelerator
to wide open throttle.

462 Vehicle Care
Caution
To avoid surface damage on
wheels and wheel trim, do
not use strong soaps,
chemicals, abrasive polishes,
cleaners, or brushes. Use
only GM approved cleaners.
Do not drive the vehicle
through an automatic car
wash that uses silicon
carbide tire/wheel cleaning
brushes. Damage could
occur and the repairs would
not be covered by the
vehicle warranty.
Brake System
Visually inspect brake lines
and hoses for proper hook-up,
binding, leaks, cracks, chafing,
etc. Inspect disc brake pads
for wear and rotors for
surface condition. Inspect
brake linings/shoes for wear
or cracks. Inspect all other
brake parts.
Steering, Suspension, and
Chassis Components
Visually inspect steering,
suspension, and chassis
components for damaged,
loose, or missing parts or signs
of wear at least once a year.
Inspect power steering for
proper attachment,
connections, binding, leaks,
cracks, chafing, etc.
Visually check constant
velocity joint boots and axle
seals for leaks.
Body Component
Lubrication
Lubricate all key lock cylinders,
hood hinges, liftgate hinges,
and the steel fuel door hinges,
unless the components are
plastic. Applying silicone
grease on weatherstrips with
a clean cloth will make them
last longer, seal better, and
not stick or squeak.
Underbody Maintenance
Every six months, use plain
water to flush any corrosive
materials from the underbody.
Take care to thoroughly clean
any areas where mud and
other debris can collect.
Do not directly power wash
the transfer case and/or
front/rear axle output seals.
High pressure water can
overcome the seals and
contaminate the fluid.
Contaminated fluid will
decrease the life of the
transfer case and/or axles and
should be replaced.
Sheet Metal Damage
If the vehicle is damaged and
requires sheet metal repair or
replacement, make sure the
body repair shop applies
anti-corrosion material to
parts repaired or replaced to
restore corrosion protection.
