Line Lock, which could cause
injury to persons or property
located nearby. Only use
Line Lock on a closed track
where there is a large clear
(Continued)
Warning (Continued)
area around all sides of the
vehicle. Be ready to apply
the brakes immediately if the
vehicle begins to move. Do
not use Line Lock in an area
that is accessible to the
public or where people or
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.
.The vehicle must be in D

transmission or 1 (First) gear
for a manual transmission.
.The parking brake must not
be engaged.
.The vehicle must be stopped
on level ground. The

268 Driving and Operating
The vehicle may have an
electric steering column lock.
The lock is activated when the
vehicle is switched to OFF and
the driver door is opened.
A sound may be heard as the
lock actuates or releases. The
steering column lock may not
release with the wheels
turned off center. If this
happens, the vehicle may not
start. Move the steering wheel
from left to right while
attempting to start the
vehicle. If this does not work,
the vehicle needs service.
Do not turn the engine off
when the vehicle is moving.
This will cause a loss of power
assist in the brake and
steering systems and disable
the airbags.
If the vehicle must be shut off
in an emergency:1. Brake using a firm and steady pressure. Do not
pump the brakes
repeatedly. This may deplete power assist,
requiring increased brake
pedal force.
2. Shift the vehicle to N (Neutral). This can be
done while the vehicle is
moving. After shifting to
N (Neutral), firmly apply the
brakes and steer the
vehicle to a safe location.
3. Come to a complete stop. Shift to P (Park) with an
automatic transmission,
or Neutral with a manual
transmission. Turn the
ignition off.
4. Set the parking brake. See Electric Parking Brake
0288.
{Warning
Turning off the vehicle while
moving may cause loss of
power assist in the brake
and steering systems and
disable the airbags. While
driving, only shut the vehicle
off in an emergency. If the vehicle cannot be pulled
over, and must be shut off
while driving, press and hold
ENGINE START/STOP for
longer than two seconds,
or press twice within
five seconds.

270 Driving and Operating
If the remote key is not in
the vehicle, if there is
interference, or if the
remote key battery is low,
a Driver Information
Center (DIC) message will
display. See Remote Key
Operation09.
Caution
Cranking the engine for long
periods of time, by pressing
ENGINE START/STOP
immediately after cranking
has ended, can overheat and
damage the cranking motor,
and drain the battery. Wait
at least 15 seconds between
each try, to let the cranking
motor cool down.
2. If the engine does not start after five to 10 seconds,
especially in very cold
weather (below −18 °C or
0 °F), it could be flooded
with too much gasoline.
Try pushing the
accelerator pedal all the
way to the floor and hold it there, then press ENGINE
START/STOP for up to a
maximum of 15 seconds.
Wait at least 15 seconds
between each try, to allow
the cranking motor to cool
down. When the engine
starts, let 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 accessory
mode. The DIC displays SHIFT
TO PARK. Once the shift lever
is moved to P (Park), the
vehicle turns off.
If the vehicle has a manual
transmission, before getting
out of the vehicle, shift to
1 (First) or R (Reverse) and
apply the parking brake. Then
turn off the ignition off by
pressing ENGINE START/
STOP and release the clutch
pedal when the engine has
stopped.
If the remote key is not
detected inside the vehicle
when it is turned off the DIC
displays a message.
Stop/Start System
If equipped, the Stop/Start
system will shut off the engine
to help conserve fuel. It has
components designed for the
increased number of starts.

Parking over Things
That Burn
{Warning
Things that can burn could
touch hot exhaust parts
under the vehicle and ignite.
Do not park over papers,
leaves, dry grass, or other
things that can burn.
Active Fuel
Management
This vehicle's engine may be
equipped with Active Fuel
Management, which allows the
engine to operate on either all
of its cylinders, or in reduced
cylinder operation mode,
depending on the driving
conditions.
When less power is required,
such as cruising at a constant
vehicle speed, the system will
operate in reduced cylinder
operation mode, allowing the
vehicle to achieve better fueleconomy. When greater
power demands are required,
such as accelerating from a
stop, passing, or merging onto
a freeway, the system will
maintain full-cylinder
operation.
If the vehicle has an Active
Fuel Management indicator,
see Driver Information Center
(DIC) for more information on
using this display.
Extended Parking
It is best not to park with the
vehicle running. If the vehicle is
left running, be sure it will not
move and there is adequate
ventilation.
See Shifting Into Park
0273
and
Engine Exhaust 0276.
If the vehicle is left parked and
running with the remote key
outside the vehicle, it will
continue to run for up to
15 minutes.
