too high.
.The oil pressure is low.
.The 30 minutes of engine run time
have been used.
.The vehicle is not in P (Park).
Door Locks
{Warning
Unlocked doors can be dangerous.
.Passengers, especially children,
can easily open the doors and
fall out of a moving vehicle. The
doors can be unlocked and
opened while the vehicle is
moving. The chance of being
thrown out of the vehicle in a
crash is increased if the doors are
not locked. So, all passengers
should wear seat belts properly
and the doors should be locked
whenever the vehicle is driven.(Continued)
Warning (Continued)
.Young children who get into
unlocked vehicles may be unable
to get out. A child can be
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
vehicle. Locking the doors can
help prevent this from
happening.
Always take your remote key with you
when exiting the vehicle to prevent
being locked out. To lock or unlock
the doors from outside the vehicle:
.PressQorKon the remote key.
See Remote Keyless Entry (RKE)
System Operation 07.
.Use the mechanical key in the
driver door. The key lock cylinder is
covered with a cap. See
“Driver Door Key Lock Cylinder
Access (In Case of Dead Battery)”
later in this section.
To lock or unlock the doors from
inside the vehicle:
.PressQorKon the power door
lock switch.
.Pull the front door handle once to
open the door. Pull the rear door
handle once to unlock and once
more to open the door.

214 DRIVING AND OPERATING
The front, if equipped with AWD, and
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. SeeRecommended
Fluids and Lubricants 0392.
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
drive as long or as fast the first
time the vehicle is driven on the
track or raced.
Engine Oil
Check the oil level often during track
events and competitive driving and
keep the oil level at or near the
upper mark.
Fuel
Use premium unleaded gasoline with
a posted octane rating of 93 at a track
event. Unleaded gasoline with a
posted octane rating of 91 may be
used, but performance will be
degraded. See Prohibited Fuels 0298.
Automatic Transmission Fluid
Have the transmission fluid set to the
track specific oil level prior to track
usage. Transmission fluid should be
changed after every 15 hours of track
usage. Any transmission level set or
change should be performed at your
dealer.
Brakes
Brake cooling can be improved if the
front brake disc splash shield and
front tire deflector are removed.
Removing the shield will require that
the suspension bushings and wheel
speed sensor wires visible to the brake
disc be protected with insulated
thermal wrapping.
Caution
Removing the splash shield can
degrade wet braking performance,
as well as introduce brake pedal
pulsation, due to brake disc
exposure to road debris. Only
remove the front brake disc splash
shield and front tire deflector when
driving in track events.
Brake Pad Wear Sensors
(V-Series Only)
If equipped, the brake pad wear
sensors need to be removed from the
brake calipers prior to any track or
racing event. The original sensors can
be reinstalled if significant brake pad
wear is not observed. The sensor
should not extend beyond the brake
pad surface at the rotor contact.
If this condition is observed, the brake
pad life system needs to be disabled
until a new set of brake pads and
sensors are installed and the system
reset.
