property are located near the
vehicle.
Caution
Attempting to shift when the drive
wheels are spinning and do not
have traction may cause damage to
the transmission. Damage caused
by misuse of the vehicle is not
covered by the vehicle warranty. Do
not attempt to shift when the drive
wheels do not have traction.
Line Lock allows for locking the front
brakes independently of the rear
brakes. This allows the rear tires to
spin when the throttle is applied.
To enter Line Lock, all of these
conditions must be met:
.The vehicle must be in Track Mode.
.Performance Traction Management
(PTM) Mode must be enabled.
.The steering wheel must be straight.
.The driver door must be closed.

go of the button and the
accelerator. If the vehicle starts
briefly but then stops again, do the
same thing. This clears the extra
gasoline from the engine. Do not
race the engine immediately after
starting it. Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Stopping the Engine
If the vehicle has an automatic
transmission, move the shift lever to
P (Park) and press and hold ENGINE
START/STOP on the instrument panel,
until the engine shuts off. If the shift
lever is not in P (Park), the engine
shuts off and the ignition goes to
ACC/ACCESSORY. The DIC displays
SHIFT TO PARK. Once the shift lever
is moved to P (Park), the vehicle
turns off.

feature causes the engine to shut
off while the vehicle is still on. Do
not exit the vehicle before shifting
to P (Park). The vehicle may restart
and move unexpectedly. Always
shift to P (Park), and then turn the
ignition off before exiting the
vehicle.
