Warning (Continued)
perform these procedures
properly could cause
malfunction, potentially
resulting in death, personal
injury, or damage to the
vehicle or property. Do not
attempt to perform these
adjustments or procedures
unless properly qualified.
{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. See Capacities
and Specifications0480 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 0292.
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.

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(Continued)
Warning (Continued)
cargo to the driver plus one
passenger with no additional
cargo.
{Warning
Track/course loads wear
tires both on the tread and
internal to the tire. When
driven in track/course
conditions, even if tread is
not worn down to the
treadwear indicator, tires
must be replaced after the
equivalent of two tanks of
fuel or approximately 160 km
(100 mi).
