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.

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
0423.
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

runs faster than the idle
speed. This keeps the battery
charged to restart the vehicle
and to signal for help with the
headlamps. Do this as little as
possible, to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle
when stuck in sand, mud, ice,
or snow.
The Traction Control System
(TCS) can often help to free a
stuck vehicle. See Traction
Control/Electronic Stability
Control0290.
If TCS cannot free the vehicle,
turn TCS off and use the
rocking method. See “Rocking
the Vehicle to Get it Out”
following.
{Warning
If the vehicle's tires spin at
high speed, they can
explode, and you or others

could be injured. The vehicle
can overheat, causing an
engine compartment fire or
other damage. Spin the
wheels as little as possible
and avoid going above
56 km/h (35 mph).
Rocking the Vehicle to Get
it Out
Turn the steering wheel left
and right to clear the area
around the front wheels. Turn
off any traction system. Shift
back and forth between
R (Reverse) and a low forward
gear, spinning the wheels as
little as possible. To prevent
transmission wear, wait until
the wheels stop spinning
before shifting gears. Release
the accelerator pedal while
shifting, and press lightly on
the accelerator pedal when
the transmission is in gear.
Slowly spinning the wheels in
the forward and reverse directions causes a rocking
motion that could free the
vehicle. If that does not get
the vehicle out after a few
tries, it might need to be
towed out. If the vehicle does
need to be towed out, see

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

should never exceed
XXX kg or XXX lbs." on
your vehicle’s placard.
2.Determine the combined
weight of the driver and
passengers that will be
riding in your vehicle.
3.Subtract the combined
weight of the driver and
passengers from
XXX kg or XXX lbs.
4.The resulting figure
equals the available
amount of cargo and
luggage load capacity.
For example, if the
"XXX" amount equals
1400 lbs. and there will
be five 150 lb
passengers in your
vehicle, the amount of
available cargo and
luggage load capacity is
650 lbs. (1400-750 (5 x
150) = 650 lbs.)
5.Determine the combined
weight of luggage and
cargo being loaded on
the vehicle. That weight
may not safely exceed
the available cargo and
luggage load capacity
calculated in Step 4.
6.If your vehicle will be
towing a trailer, load
from your trailer will be
transferred to your
vehicle. Consult this
manual to determine
how this reduces the
available cargo and
luggage load capacity of
your vehicle.”

268 Driving and Operating
Warning (Continued)
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)
0267 or
Shifting Into Park (Electronic
Shifter) 0268. If you are
towing a trailer, see Driving
Characteristics and Towing
Tips 0358. 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).
