Steering
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.
See your dealer if there is a
problem.
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, power
assist may be reduced.
Normal use of the power steering
assist should return when the
system cools down.
See specific vehicle steering
messages underService Vehicle
Messages 0129. 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.
. The 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 gostraight down the roadway.
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three
control systems:
.Braking Skid —wheels are not
rolling.
. Steering or Cornering Skid —
too much speed or steering in a
curve causes tires to slip and
lose cornering force.
. Acceleration Skid —too much
throttle causes the driving
wheels to spin.
Defensive drivers avoid most skids
by taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible.
If the vehicle starts to slide, follow
these suggestions:
. Ease your foot off the
accelerator pedal and steer the
way you want the vehicle to go. The vehicle may straighten out.
Be ready for a second skid if it
occurs.
. Slow down and adjust your
driving according to weather
conditions. Stopping distance
can be longer and vehicle
control can be affected when
traction is reduced by water,
snow, ice, gravel, or other
material on the road. Learn to
recognize warning clues —such
as enough water, ice, or packed
snow on the road to make a
mirrored surface —and slow
down when you have any doubt.
. Try to avoid sudden steering,
acceleration, or braking,
including reducing vehicle speed
by shifting to a lower gear. Any
sudden changes could cause
the tires to slide.
Remember: Antilock brakes help
avoid only the braking skid.

Caution
During a first time track or racing
event, high rear axle
temperatures can occur. Damage
could be caused to the rear axle
and would not be covered by the
vehicle warranty. Do not drive as
long or as fast the first time the
vehicle is driven on the track or
raced.
Axles must have 885 km (500 mi)
before being used in track driving.
The rear axle fluid temperatures
may be higher than when driving in
severe conditions. Drain and refill
with new fluid after the first racing or
competitive driving event, and then
after every 24 hours of racing or
competitive driving. See

General Information
If reduced performance is
experienced during track events or
competitive driving, turning off the
A/C will help to improve engine
performance.
Maintain a mixture of 40%
DEX-COOL coolant and 60% clean,
drinkable water to optimize engine
performance.
The front license plate bracket or
aero panel should be removed for
track events and competitive driving
to improve engine performance.
Rotor Cooling Ring, If
Equipped
The following installation procedure
is for the Z51 Performance
Package, and is only if the vehicle is
equipped with front dual cast brake
rotors along with the supplied brake
cooling ring kit. See your dealer for
information.
If the vehicle has the Z51
Performance Package and
equipped with a one piece brake
rotor, a cooling ring is not required.
Caution
Do not leave rotor cooling rings
installed after a track event, as
this can cause corrosion with
long-term use. Rotor cooling rings
are for track use only. Track
driving without the rotor cooling
rings may result in brake
pedal fade.
Installation: 1. Remove the front wheels.
2. Cut three 150 mm (6 in) lengths of safety wire specified
to T304 Stainless Steel,
0.041 in nominal diameter, not
included.
3. Form each into a U shape with a 20 mm (0.75 in) flat area in
the center of the wire.
4. Place the rotor ring in the gap between the rotor brake plate
and rotor hat, with the holes on
each side of the rotor spoke on
the outboard side of the rotor.
5. Place the U-shaped wirethrough the holes in the rotor
cooling ring.
6. Bring the ends of the wire tight around the corresponding rotor
spoke.
7. Twist the safety wire into six to eight twists per 2.54 cm (1 in).
8. Bend the twisted wire so it is flush with the inside of the rotor
ring to prevent contact with the
caliper or brake hoses.
9. Verify that the rotor rings and safety wire do not contact any
other components.

10. Reinstall the wheel using thespecific wheel nut torque. See
Capacities and
Specifications 0321.
If additional brake cooling is
required, the grille mesh in the lower
corners of the front grille in front of
the brake duct can be removed.
This is not reversible, and a
replacement grille will not be
covered by the vehicle warranty.
If this is done, it is recommended
that the gap between the fascia and
the cooling duct be taped over.
Brake Burnishing
New brake pads must be burnished
before racing or other competitive
driving.
Caution
Performing the brake burnish
procedure on a base brake
system can result in brake
damage.
Caution
The new vehicle break-in period
should be completed before
performing the brake burnish
procedure, otherwise damage
may occur to the powertrain/
engine. See New Vehicle
Break-In 0181.
Caution
Brake pedal fade will occur during
any track burnish procedure and
can cause brake pedal travel and
force to increase. This could
extend stopping distance until the
brakes are fully burnished.
When this procedure is performed
as instructed, it will not damage the
brakes. The brake pads will smoke
and produce an odor. The braking
force and pedal travel may increase.
After the procedure, the brake pads
may appear white at the rotor
contact. Perform this procedure only on dry
pavement, in a safe manner, and in
compliance with all local and state
ordinances/laws regarding motor
vehicle operation.
Brake Burnish Procedure (Z51
Performance Package, Grand
Sport without Z07, and Z06
without Z07 Performance Package
or Z06 without J57 Ceramic
Brakes)
1. Apply the brakes 25 times starting at 100 km/h (60 mph) to
50 km/h (30 mph) while

Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep-standing or flowing water.
{Warning
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water
can build up under the vehicle's
tires so they actually ride on the
water. This can happen if the road is
