Electric Power Steering
The vehicle has electric power
steering. It does not have power
steering fluid. Regular maintenance is
not required.
If power steering assist is lost due to a
system malfunction, the vehicle can
be steered, but may require increased
effort.
If the steering wheel is turned until it
reaches the end of its travel and is
held against that position for an
extended period of time, power
steering assist may be reduced.
If the steering assist is used for an
extended period of time while the
vehicle is not moving, power assist
may be reduced.
Normal use of the power steering
assist should return when the system
cools down.
See your dealer if there is a problem.
Curve Tips
.Take curves at a reasonable speed.
.Reduce speed before entering a
curve.
.Maintain a reasonable steady speed
through the curve.
.Wait until the vehicle is out of the
curve before accelerating gently into
the straightaway.
Steering in Emergencies
.There are some situations when
steering around a problem may be
more effective than braking.
.Holding both sides of the steering
wheel allows you to turn
180 degrees without removing
a hand.
.Antilock Brake System (ABS) allows
steering while braking.
Off-Road Recovery
The vehicle's right wheels can drop off
the edge of a road onto the shoulder
while driving. Follow these tips:1. Ease off the accelerator and then, if there is nothing in the way, steer
the vehicle so that it straddles the
edge of the pavement.
2. Turn the steering wheel about one-eighth of a turn, until the right
front tire contacts the
pavement edge.
3. Turn the steering wheel to go straight down the roadway.

Launch Control
If equipped, Launch Control is
available within Competitive 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.
Launch Control will initially limit
engine speed as you rapidly apply the
accelerator pedal to wide open
throttle. Allow the engine rpm to
stabilize. A smooth, quick release of
the brake pedal, while maintaining the
fully pressed accelerator pedal, will
manage wheel slip.
After the vehicle is launched, the
system continues in Competitive
Driving Mode or PTM.
Competitive Driving Mode, PTM, and
Launch Control are systems designed
for a closed course race track and not
intended for public roads. The systems
are not intended to compensate for
lack of driver experience or familiarity
with the race track.Limited-Slip Differential
If equipped, the Electronic
Limited-Slip Differential (eLSD) is
automatically activated. eLSD actively
monitors vehicle sensors and driver
inputs to determine the amount of
change for the conditions. With eLSD,
the vehicle has:
.Enhanced high-speed control.
.Improved traction through corners,
allowing more acceleration.
.More precise steering.
.Increased vehicle agility.
.Integration with StabiliTrak/
Electronic Stability Control (ESC).
For vehicles with eLSD, driven under
severe conditions, the rear axle fluid
should be changed. See Competitive
Driving Mode 0265 and
Maintenance Schedule 0410.

{Warning
Do not touch heater or radiator
hoses, or other engine parts. They
can be very hot and can burn you.
Do not run the engine if there is a
leak; all coolant could leak out.
That could cause an engine fire and
can burn you. Fix any leak before
driving the vehicle.
Caution
Do not use anything other than a
mix of DEX-COOL coolant that
meets GM Standard GMW3420 and
clean, drinkable water. Anything
else can cause damage to the
engine cooling system and the
vehicle, which would not be covered
by the vehicle warranty.
Engine Coolant
The cooling system in the vehicle is
filled with DEX-COOL engine coolant.
SeeMaintenance Schedule 0410 and
Recommended Fluids and Lubricants
0 420. The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating, see
Engine Overheating
0347.
What to Use
{Warning
Do not touch heater or radiator
hoses, or other engine parts. They
can be very hot and can burn you.
Do not run the engine if there is a
leak; all coolant could leak out.
That could cause an engine fire and
can burn you. Fix any leak before
driving the vehicle.
Use a 50/50 mixture of clean
drinkable water and DEX-COOL
coolant. This mixture:
.Gives freezing protection down to
−37 °C (−34 °F), outside temperature.
.Gives boiling protection up to
129 °C (265 °F), engine temperature.
.Protects against rust and corrosion.
.Will not damage aluminum parts.
.Helps keep the proper engine
temperature.
Caution
Do not use anything other than a
mix of DEX-COOL coolant that
meets GM Standard GMW3420 and
clean, drinkable water. Anything
else can cause damage to the
engine cooling system and the
vehicle, which would not be covered
by the vehicle warranty.
Never dispose of engine coolant by
putting it in the trash, pouring it on
the ground, or into sewers, streams,
or bodies of water. Have the coolant
changed by an authorized service
center, familiar with legal
requirements regarding used coolant
disposal. This will help protect the
environment and your health.
Checking Coolant
The vehicle must be on a level surface
when checking the coolant level.
It is normal to see coolant moving in
the upper coolant hose return line
when the engine is running. It is also
normal to see bubbles entering the
surge tank through the small hose.

brake dust on the wheels and calipers
as compared to standard brake linings.
This is normal.
To help reduce squeal, high
performance brake pads are treated
with an anti-squeal paste that may
need to be reapplied periodically as
part of normal vehicle maintenance.
The anti-squeal paste will dissipate
over time. Also, the use of wheel
cleaners or power washers directly on
the brake calipers may remove the
anti-squeal paste from the brake pads.
It may be necessary to reapply the
anti-squeal paste if it is removed
during cleaning.
If brake squeal is excessive, the
anti-squeal paste should be reapplied.
The anti-squeal paste should always
be reapplied whenever the brake pads
are removed or replaced. See your
dealer for service.
Brake Pedal Travel
See your dealer if the brake pedal does
not return to normal height, or if
there is a rapid increase in pedal
travel. This could be a sign that brake
service may be required.
Replacing Brake System Parts
Always replace brake system parts
with new, approved replacement parts.
If this is not done, the brakes may not
work properly. The braking
performance can change in many
ways if the wrong brake parts are
installed or if parts are improperly
installed.
The Brake Fade Warning Assist
system is designed for use with the
factory-installed brake pads or GM
approved replacement pads. If the
brake pads on the vehicle need to be
replaced, use GM-approved brake
pads. If this is not done, the brake
fade warning system may not function
properly.
High Performance Brake Lining
Car Wash and Extended
Parking Care
If equipped with high performance
brake components, binding or
clunking may be noticeable after
extended parking or in cold weather
when the brakes have been wet, such
as when driving in the rain or after a
car wash. The clunking is normal forbrakes with high performance brake
linings and does not affect the
operation of the brakes. When driving,
normal braking will allow for the
brakes to feel smooth and the
clunking to go away. If the vehicle is
washed before overnight parking or
long term storage, drive it and apply
the brakes several times to thoroughly
dry the brakes.
Brake Rotor Wear (V-Series
Blackwing With J57 Carbon
Ceramic Rotors)
The V-Series Blackwing with J57 has
carbon ceramic brake rotors. The
rotors should be visually inspected
whenever the brake pads are replaced.
Carbon ceramic brake rotors also need
to be weighed before brake pads are
replaced to confirm that the rotor
mass is greater than the wear-out
mass printed on the rotor. The rotor
can be reused if the weight of the
rotor is above the mass limit. Carbon
ceramic brake rotors inspection and
weighing methods can be found in the
service manual.
