208 Driving and Operating Leaving the Vehicle with the
Engine Running
{ WarningIt can be dangerous to leave the
vehicle with the engine running.
It could overheat and catch fire.
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 0 207 .
If you are towing a trailer, see
Driving Characteristics and
Towing Tips 0 255 . If you have to leave the vehicle with
the engine running, the vehicle must
be in P (Park) and the parking brake
set. After shifting into P (Park), try to
move the shift lever out without first
pushing the button on the shift lever.
If you can, the shift lever was not
fully locked into 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, the
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so you
can shift out of P (Park). Shifting out of Park This vehicle is equipped with an
electronic shift lock release system.
The shift lock release is designed to
prevent movement of the shift lever
out of P (Park), unless the ignition is
in ON/RUN and the brake pedal is
applied.
The shift lock release is always
functional except in the case of an
uncharged or low voltage (less than
9 volt) battery.
If the vehicle has an uncharged
battery or a battery with low voltage,
try charging or jump starting the
battery. See Jump Starting - North
America 0 327 for more information.

stuck, do not spin the tires. When
stopping on a hill, use the brakes
to hold the vehicle in place.
While in Sport Mode, the vehicle
monitors driving behavior and
automatically enables performance
shift features when spirited driving is
detected. These features maintain
lower transmission gears to
increase available engine braking
and improve acceleration response.
The vehicle will exit these features
and return to normal operation after
a short period when no spirited
driving is detected. See Driver Mode
Control 0 219 . Manual Mode Tap Shift
CautionDriving with the engine at a high
rpm without upshifting while using

Tips 0 255 . Brake Assist This vehicle has a brake assist
feature designed to assist the driver
in stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle. The
stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.
Minor brake pedal pulsation or
pedal movement during this time is
normal and the driver should
continue to apply the brake pedal as
the driving situation dictates. The
brake assist feature will
automatically disengage when the
brake pedal is released or brake
pedal pressure is quickly
decreased. Hill Start Assist (HSA) HSA may automatically activate
when the vehicle is stopped on a hill
and Automatic Vehicle Hold (AVH)
is not enabled. This feature is
designed to prevent the vehicle from
rolling, either forward or rearward,
during vehicle drive off. During the
transition from releasing the brake
pedal to accelerating to drive off on
a hill, HSA holds the braking
pressure to prevent rolling. HSA will
not activate if the vehicle is in a
drive gear and facing downhill or if
the vehicle is facing uphill and in
R (Reverse).
