{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

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.

Shifting Into Park
(Mechanical Shifter)
1. Hold the brake pedal down and setthe parking brake. See Electric
Parking Brake 0254.
2. Move the shift lever into P (Park) by holding in the button on the
shift lever and pushing the shift
lever all the way toward the front
of the vehicle.
3. Turn the ignition off.
Leaving the Vehicle with the
Engine Running
{Warning
It can be dangerous to leave the
vehicle with the engine running.
It could overheat and catch fire.
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle can
move suddenly. You or others could
be injured. To be sure the vehicle
will not move, even when you are
on fairly level ground, always set
the parking brake and move the
shift lever to P (Park). See Shifting
Into Park (Mechanical Shifter) 0238
or
Shifting Into Park (Electronic Shifter)
0 239. If you are towing a trailer,
see Driving Characteristics and
Towing Tips 0315. If you have to leave the vehicle with
the engine running, be sure the
vehicle is in P (Park) and the parking
brake is set before you leave it. After
you have moved the shift lever into
P (Park), hold the regular brake pedal
down. Then, see if you can move the
shift lever away from P (Park) without
first pressing the button.
If you can, it means that the shift
lever was not fully locked in P (Park).
Torque Lock
Torque lock is when the weight of the
vehicle puts too much force on the
parking pawl in the transmission. This
happens when parking on a hill and
shifting the transmission into P (Park)
is not done properly and then it is
difficult to shift out of P (Park). To
prevent torque lock, set the parking
brake and then shift into P (Park). To
find out how, see
“Shifting Into Park”
listed previously.
If torque lock does occur, your vehicle
may need to be pushed uphill by
another vehicle to relieve the parking
pawl pressure, so you can shift out of
P (Park).

accelerator pedal when accelerating
from a stop. Also, fully release the
accelerator pedal during gear
changes. This will allow the clutch
to cool and should prevent further
clutch slip while the clutch pedal is
fully released. If this message
displays repeatedly, see your dealer.
Repeated clutch slip could cause
permanent damage.
Caution
The message TRANSMISSION IS
HOT —SLOW DOWN displays and
a chime sounds if the manual
transmission fluid is hot and
vehicle speed is high. Driving with
the manual transmission fluid

on it. Add washer fluid until the tank
is full. SeeEngine Compartment
Overview 0326 for reservoir location.
Caution
.Do not use washer fluid that
contains any type of water
repellent coating. This can cause
the wiper blades to chatter
or skip.
.Do not use engine coolant
(antifreeze) in the windshield
washer. It can damage the
windshield washer system and
paint.
.Do not mix water with
ready-to-use washer fluid. Water

expansion if freezing occurs,
which could damage the tank if
it is completely full.
Brakes
Disc brake linings, except J57 V-Series
Blackwing with carbon ceramic brakes,
have built-in wear indicators that
make a high-pitched warning sound
when the brake linings are worn and
new linings are needed. The sound
can come and go or can be heard all
the time when the vehicle is moving,
except when applying the brake pedal
firmly. The V-Series Blackwing has
electronic pad wear sensors. See Brake
Pad Life System (If Equipped) 0346
{Warning
The brake wear warning sound
means that soon the brakes will not
work well. That could lead to a
crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Caution
Continuing to drive with worn-out
brake linings could result in costly
brake repairs.
Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake linings for wear and
evenly tighten wheel nuts in the
proper sequence to torque
specifications. See Capacities and
Specifications 0424.
Brake linings should be replaced as
complete axle sets.
Brake Squeal and Brake Dust
Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied, clearing up
following several applies. This does
not mean something is wrong with
the brakes.
Vehicles equipped with high
performance brake systems provide
superior fade resistance, but will
produce increased brake squeal and
