and StabiliTrak/ESC OFF lightgwill
come on in the instrument cluster.
TCS does not limit wheel spin, the
Electronic Limited-Slip Differential
(eLSD) allows increased vehicle agility,
and more effort is required to turn the
steering wheel. See “Limited-Slip Axle
(V-Series Only)” later in this section.
Adjust your driving accordingly.
Press
Yagain, or turn the ignition to
ACC/ACCESSORY and restart the

Caution
When traction control is turned off,
or Competitive Driving Mode is
active, it is possible to lose traction.
Performance Traction
Management (V-Series Only)
Performance Traction Management
(PTM) integrates the Traction Control,
StabiliTrak/Electronic Stability Control (ESC), and Magnetic Ride Control
systems to provide improved and
consistent performance when
cornering. The amount of available
engine power is based on the mode
selected, track conditions, driver skill,
and the radius of each corner.
This light is on when the vehicle is in
the PTM mode.
To select this optional handling mode,
the vehicle mode must be Track. Then
quickly press
Yon the steering
wheel two times. PERF TRAC 1 - WET
ACTIVE HANDLING ON displays in
the DIC.
When PTM is active, the up and down
buttons will no longer change Drive
Modes, but instead change PTM
modes. To select a mode while in PTM, press
the Driver Mode Control/PTM buttons
on the center console.
To experience the performance benefit
of this system, after entering a curve
and at the point where normal
acceleration occurs, fully push the
accelerator pedal. The PTM system
will modify the level of engine power
for a smooth and consistent
corner exit.
The PTM system contains five modes.
These modes are selected by pressing
the Driver Mode Control/PTM buttons
on the center console. Scroll up or
down through modes 1-5 by pressing
the MODE up and down button. The
following is a DIC display description
and the recommended usage of
each mode:

VEHICLE CARE 321
Caution
Chrome wheels and chrome wheel
trim may be damaged if the vehicle
is not washed after driving on roads
that have been sprayed with
magnesium chloride or calcium
chloride. These are used on roads
for conditions such as dust and ice.
Always wash the chrome with soap
and water after exposure.
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 silicone 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 drum 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 hinge, unless the
components are plastic. Applying
silicone grease on weatherstrips with aclean cloth will make them last
longer, seal better, and not stick or
squeak.
Underbody Maintenance
At least twice a year, spring and fall,
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.

SERVICE AND MAINTENANCE 335
.To avoid break-down or failure to
start the vehicle, maintain a
battery with full cranking power.
. Trained dealer technicians have
the diagnostic equipment to test
the battery and ensure that the
connections and cables are
corrosion-free.
Belts
. Belts may need replacing if they
squeak or show signs of cracking
or splitting.
. Trained dealer technicians have
access to tools and equipment to
inspect the belts and recommend
adjustment or replacement when
necessary.
Brakes
Brakes stop the vehicle and are crucial
to safe driving.
. Signs of brake wear may include
chirping, grinding, or squealing
noises, or difficulty stopping. .
Trained dealer technicians have
access to tools and equipment to
inspect the brakes and recommend
quality parts engineered for the
vehicle.
Fluids
Proper fluid levels and approved fluids
protect the vehicle’s systems and
components. See Recommended Fluids
and Lubricants 0337 for GM approved
fluids.
. Engine oil and windshield washer
fluid levels should be checked at
every fuel fill.
. Instrument cluster lights may
come on to indicate that fluids
may be low and need to be filled.
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 stopping
distance, or uneven tire wear.
. As part of the multi-point
inspection, trained dealer
technicians can visually inspect
the shocks and struts for signs of
