Service
All vehicles have a label underhood that
identifies the refrigerant used in the vehicle.
The refrigerant system should only be
serviced by trained and certified technicians.
The air conditioning evaporator should never
be repaired or replaced by one from a
salvage vehicle. It should only be replaced
by a new evaporator to ensure proper and
safe operation.
During service, all refrigerants should be
reclaimed with proper equipment. Venting
refrigerants directly to the atmosphere is
harmful to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite, or other
health-based concerns.
The air conditioning system requires periodic
maintenance. See Maintenance Schedule
0 293.

178 Driving and Operating
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 assist is used for an extended
period of time while the vehicle is not
moving, power assist may be reduced.
If the steering wheel is turned until it
reaches the maximum rotation and is held
at that position for an extended period of
time, power steering 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.
Dynamic Rack Travel
If equipped with Magnetic Ride Control,
Dynamic Rack Travel (DRT) is a steering
system feature which enhances driving by
providing additional maximum steering
wheel rotation to allow a tighter turning
radius during low speed driving conditions.
If the vehicle speed increases or if the
suspension encounters significant wheel
travel, such as a driveway, while at
maximum steering rotation, DRT may gently
push the steering back a small amount to
prevent the front tires from contacting the
vehicle. This is normal operation. There is no
customer interface or display for this
feature. DRT is not available when in
Track Mode.
Curve Tips
.Take curves at a reasonable speed.
.Reduce speed before entering a curve.
.Maintain a reasonable and 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.

182 Driving and Operating
The driver should immediately start a cool
down lap if on the track. If this message
displays, take the vehicle to be serviced at
your dealer.
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-In0190.
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 Burnishing Procedure
This brake burnish procedure should only be
run on vehicles with the J55 Z51 factory
equipped brake system.
1. Apply the brakes 25 times starting at 100 km/h (60 mph) to 50 km/h (30 mph)
while decelerating at 0.4 g. This is a
medium brake application. Drive for at
least 1 km (0.6 mi) between applying the
brakes. This first step may be skipped if
there are more than 320 km (200 mi) on
the brake pads.
2. Apply the brakes 25 times starting at 100 km/h (60 mph) to 25 km/h (15 mph)
while decelerating at 0.8 g. This is a hard
brake application without activating the
Antilock Brake System (ABS). Drive for at least 1 km (0.6 mi) between applications.
Depending on conditions, some increase
in brake pedal travel and brake pedal
force may be experienced.
3. Cool down: Drive at 100 km/h (60 mph) for approximately 15 km (10 mi) without
using the brakes.
4. Apply the brakes 25 times from 100 km/h (60 mph) to 50 km/h (30 mph)
while decelerating at 0.4 g. This is a
medium brake application. Drive for at
least 1 km (0.6 mi) between applications.
As with all high performance brake systems,
some amount of brake squeal is normal.
Alternative Closed Course Brake Burnishing
Procedure
This brake burnish procedure should only be
run on vehicles with the J55 Z51 factory
equipped brake system.
This procedure should only be run on a
track and only on dry pavement. Brake
pedal fade will occur during this track
burnish procedure and can cause brake pedal
travel and force to increase. This could
extend stopping distance until the brakes
are fully burnished.
