{Warning
Unlocked doors can be dangerous.
.Passengers, especially children,
can easily open the doors and

overcome by extreme heat and
can suffer permanent injuries or
even death from heat stroke.
Always lock the vehicle whenever
leaving it.
.Outsiders can easily enter
through an unlocked door when
you slow down or stop the

DRIVING AND OPERATING 215
Brake Fluid
For track events and competitive
driving, it is recommended that the
brake fluid be replaced with a high
performance brake fluid that has a dry
boiling point greater than 279 °C
(534 °F). After conversion to the high
performance brake fluid, follow the
brake fluid service recommendations
outlined by the fluid manufacturer. Do
not use silicone or DOT-5 brake fluids.
Check the fluid level before each
competitive driving event.
Brake Fade Warning Assist
The Brake Fade Warning Assist
system monitors the performance of
the brake system. If the system
detects brake fade, or if the brake
fluid is near the boiling point, the
driver will be alerted.
Stage 1 :The Driver Information
Center (DIC) displays a “Reduce
Braking to Avoid Overheating”
message and brake pedal effort and
travel is increased. When the message
displays, the driver should decrease
brake pedal pressure. Stage 2 :
The Driver Information
Center (DIC) displays a “Brakes
Overheated Service Now ”message that
the brake fluid temperature is
excessive and is about to boil. The
system increases brake pedal effort
and travel, and will also limit vehicle
speed. 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
To prepare the brake system for track
events and racing, complete the
appropriate high performance brake
burnishing procedure described below.
New brake pads must be burnished
before racing or other competitive
driving.
Caution
These procedures are specific to the
V-Series with performance brake
linings package. This procedure
should not be run on other models
as damage may result.
Caution
The new vehicle break-in period
should be completed before
performing the brake burnishing
procedure or damage may occur to
the powertrain/engine. See New
Vehicle Break-In 0223.
When performed as instructed, this
procedure will not damage the brakes.
During the burnishing procedure, the
brake pads will smoke and produce an
odor. The braking force and pedal
travel may increase. After the
procedure is complete, the brake pads
may appear white at the rotor contact.
Run this procedure in a safe manner
and in compliance with all local and
state ordinances/laws regarding motor
vehicle operation. Run this procedure
only on dry pavement.

DRIVING AND OPERATING 223
Starting and Operating
New Vehicle Break-In
Follow these recommended guidelines
during the first 2 400 km (1,500 mi) of
driving this vehicle. Parts have a
break-in period and performance will
be better in the long run.
For the first 2 400 km (1,500 mi):
.Avoid full throttle starts and abrupt
stops.
.Do not exceed 4000 engine rpm.
.Avoid driving at any one constant
speed, fast or slow.
.Avoid downshifting to brake or slow
the vehicle when the engine speed
will exceed 4000 rpm.
.Do not let the engine labor. Never
lug the engine in high gear at low
speeds.
.Do not participate in track events,
sport driving schools, or similar
activities during this break-in
period.
.Check engine oil with every
refueling and add if necessary. Oil
and fuel consumption may be
higher than normal during the first
2 400 km (1,500 mi).
.To break in new tires, drive at
moderate speeds and avoid hard
cornering for the first
300 km (200 mi). New tires do not
have maximum traction and may
tend to slip.
.New brake linings also need a
break-in period. Avoid making hard
stops during the first
300 km (200 mi). This is
recommended every time brake
linings are replaced.
Composite Materials
This vehicle may be equipped with
parts containing carbon fiber,
sheet-molding compound, or other
composite materials. Dealer-installed
accessories may also contain
composite materials.
{Warning
Exposed edges of parts containing
carbon fiber and other composite
materials can be sharp. Contact
with these parts could result in
injury. Use caution to avoid
contacting these parts, including
when washing the vehicle. If the
parts are damaged, replace the
parts promptly with replacements
from your dealer.
{Warning
Rocker extensions may break under
pressure, resulting in property
damage or injury. Do not stand on
the rocker extension or use it as
a step.
{Warning
Rear end spoilers may break under
pressure, resulting in property
damage or injury. Do not push the
vehicle by the spoiler or use the
spoiler as a handle.
