Radio Reception
Unplug electronic devices from the
accessory power outlets if there is
interference or static in the radio.
FM
FM signals only reach about 16 to
65 km (10 to 40 mi). Although the
radio has a built-in electronic circuit
that automatically works to reduce
interference, some static can occur,
especially around tall buildings or
hills, causing the sound to fade in
and out.
AM
The range for most AM stations is
greater than for FM, especially at
night. The longer range can cause
station frequencies to interfere with
each other. Static can also occur when
things like storms and power lines
interfere with radio reception. When
this happens, try reducing the treble
on the radio.

214 DRIVING AND OPERATING
{Warning
Prior to each track event and again
before returning to public roads,
tighten the wheel nuts with a
torque wrench to the proper torque
specification. Wheel nuts that are
improperly or incorrectly tightened
can cause the wheels to become
loose or come off, resulting in a
crash. SeeCapacities and
Specifications 0424 for wheel nut
torque specifications.
Caution
Low oil levels can damage the
engine. If using the vehicle for
competitive driving, the engine may
use more oil than it would with
normal use. Check the oil level
often during competitive driving.
Competitive Driving Mode can be
selected. See Driver Mode Control
0 258.
Seat Belts
Lap-Shoulder Belt
If equipped, the driver seat belt has an
Automatic Locking Retractor (ALR).
This feature is useful in performance
driving scenarios where the driver
wants to be held in the seat more
tightly to take advantage of the
aggressive bolstering of the seat.
1. Move the seat 8-10 cm (3-4 in) rearward from the normal driving
position.
2. Pull the driver shoulder belt out as far as it will go, until it stops, to set
the lock. While holding the
shoulder belt in this position,
buckle the belt.
When the shoulder belt is released,
the retractor will make a ratchet
sound when it retracts. When the
retractor lock is set, the belt can be
tightened but not pulled out of the
retractor.
3. Adjust the belt, and then move the seat forward 8-10 cm (3-4 in) to
the desired driving position. This will secure the belt. The belt fit
should be tight, but not
uncomfortable.
To unlatch the belt, press the
button on the buckle. The belt
should return to its stowed
position.
Axle Fluid
Axles must have 2 400 km (1,500 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 your dealer
for the correct fluid.
Caution
During a first time track or racing
event, high axle temperatures can
occur. Damage could be caused to
the axle and would not be covered
by the vehicle warranty. Do not

3. Repeat the first two steps 20consecutive times, this should take
about five minutes.
4. After completing the 20 stops, cool the brakes by driving for 8 km
(5 mi) at 100 km/h (60 mph).
Alternative Closed Course Brake
Burnishing Procedure
This brake burnish procedure should
only be run on vehicles with a 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. 1. Start track lapping at lower speeds and lower braking efforts for
three minutes of driving. Allow for
increased braking distances due to
reduced brake output.
2. After Step 1, increase speed and braking effort for the next six
minutes of lapping, gradually
ending up at 90% effort. Continue to allow for increased braking
distance due to reduced brake
output.
3. Cool the brakes by lapping with minimal light braking for six
minutes.
As with all high performance brake
systems, some amount of brake squeal
is normal.
Suspension
Track Prep —Camber Set
To achieve the maximum camber
setting for track use, follow this
procedure prior to the final track
alignment.
1. Remove the Upper Radiator Baffle and both front shock tower braces.
2. Remove the strut rebound stop.

Tire Inflation Pressure
Guidelines
Tire inflation pressures affect vehicle
handling and tire life, and should be
adjusted for various types of tracks/
courses.
Inspect the tires prior to every track/
course session. Track/course driving
will reduce the tire tread life.
To maximize tire life, drive 800 km
(500 mi) prior to racetrack driving or
complete the minimum track running
that will increase the tire pressures by
35 kPa (5 psi). After this, immediately
let the tires cool to cold pressures.
Tire Inflation Pressure High Speed
See Tire Pressure for High-Speed
Operation 0371.
Tire Inflation Pressure for Track
Driving
For driving on a race course, if your
vehicle is equipped with 255/35ZR18
(94Y) and 275/35ZR18 (99Y) tires, set
cold (stationary) tire pressures to
30 psi. During track sessions, set the pressures at 35 to 38 psi for hot tire
pressures. If pressures exceed 38 psi,
bleed pressures down to 35 to 38 psi.
Return the tires to the recommended
cold tire inflation pressure when track
driving has ended.
Driving and Operating
{Warning
Operating the vehicle at high speeds
can be dangerous. Improper tire
inflation pressure can put
additional strain on the tires and
can cause a sudden failure. Make
sure the tires are in excellent
condition, and use the correct cold
tire inflation pressure for the
vehicle load and track/course.
{Warning
Tracks/courses put high loads on
tires operating at high speed, which
can lead to tire failure if not
inflated properly. Always limit
vehicle cargo to the driver plus one
passenger with no additional cargo.

might need to be towed out. If the
vehicle does need to be towed out, see
Towing the Vehicle (Electronic Shifter)
0393 or
Towing the Vehicle (Mechanical Shifter)
0 395.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can carry.
This weight is called the vehicle
capacity weight and includes the
weight of all occupants, cargo, and
all nonfactory-installed options.
Two labels on the vehicle may
show how much weight it may
properly carry: the Tire and
Loading Information label and the
Certification label.
{Warning
Do not load the vehicle any
heavier than the Gross Vehicle
Weight Rating (GVWR),
or either the maximum front or
rear Gross Axle Weight Rating
(Continued)
Warning (Continued)
(GAWR). This can cause
systems to break and change
the way the vehicle handles.
This could cause loss of control
and a crash. Overloading can
also reduce stopping
performance, damage the tires,
and shorten the life of the
vehicle.
Tire and Loading Information
Label
Label Example
A vehicle-specific Tire and
Loading Information label is
attached to the vehicle's center
pillar (B-pillar). The Tire and
Loading Information label shows
the number of occupant seating
positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.
The Tire and Loading Information
label also shows the tire size of
the original equipment tires (3)
and the recommended cold tire
inflation pressures (4). For more
information on tires and inflation
see Tires 0363 and
Tire Pressure 0370.
There is also important loading
information on the Certification
label. It may show the Gross
Vehicle Weight Rating (GVWR)
and the Gross Axle Weight Rating
(GAWR) for the front and rear
axle. See “Certification Label” later
in this section.
