person using remote start to have the
vehicle in view. Check local
regulations for any requirements.

extended by another 15 minutes,
if during the first 15 minutes
Steps 1 and 2 are repeated while the
engine is still running. An extension
can be requested 30 seconds after
starting. This provides a total of
30 minutes.
The remote start can only be
extended once.
When the remote start is extended,
the second 15-minute period is added
on to the first 15 minutes for a total
of 30 minutes.
A maximum of two remote starts, or a
remote start with an extension, are
allowed between ignition cycles.
The ignition must be turned on and
then off before the remote start
procedure can be used again.

vehicle.
.The vehicle is not off.
.The hood is not closed.
.The hazard warning flashers are on.
.There is an emission control system
malfunction.
.The engine coolant temperature is
too high.
.The oil pressure is low.
.Two remote vehicle starts or a start
with an extension have already

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.
.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 (Continued)

.Presslon the bottom of the
liftgate next to the pull cup to close.
Press any liftgate button, or the touch
pad, or
bon the RKE transmitter
while the liftgate is moving to stop it.
Pressing any liftgate button again or
pressing
btwice quickly on the RKE
transmitter restarts the operation in
the reverse direction. Pressing the
touch pad on the liftgate handle will
restart the motion, but only in the
opening direction.
Caution
Manually forcing the liftgate to
open or close during a power cycle
can damage the vehicle. Allow the
power cycle to complete.
The power liftgate may be temporarily
disabled under extreme low
temperatures, or after repeated power
cycling over a short period of time.
If this occurs, the liftgate can still be
operated manually.
If the vehicle is shifted out of P (Park)
while the power function is in
progress, the liftgate will continue to
completion. If the vehicle is
accelerated before the liftgate has
completed moving, the liftgate may
stop or reverse direction. Check for
Driver Information Center (DIC)
messages and make sure the liftgate is
closed and latched before driving.
Falling Liftgate Detection
If the power liftgate automatically
closes after a power opening cycle, it
indicates that the system is reacting
to excess weight on the liftgate or a
possible support strut failure. A repetitive chime will sound while
the falling liftgate detection feature is
operating. Remove any excess weight.
If the liftgate continues to
automatically close after opening, see
your dealer for service before using
the power liftgate.
Interfering with the power liftgate
motion or manually closing the
liftgate too quickly after power
opening may resemble a support strut
failure. This could also activate the
falling liftgate detection feature. Allow
the liftgate to complete its operation
and wait a few seconds before
manually closing the liftgate.
Obstacle Detection Features
If the liftgate encounters an obstacle
during a power open or close cycle,
the liftgate will automatically reverse
direction and move a short distance
away from the obstacle. After
removing the obstruction, the power
liftgate operation can be used again.
If the liftgate encounters multiple
obstacles on the same power cycle,
the power function will deactivate.
After removing the obstructions,

transmitter away from the rear
bumper detection area or turn the
liftgate mode to OFF when cleaning
or working near the rear bumper to
avoid accidental opening.
.Do not sweep your foot side to side.
.Do not keep your foot under the
bumper; the liftgate will not
activate.

disabled under some conditions.
If the liftgate does not respond to
the kick, open or close the liftgate
by another method or start the
vehicle. The feature will be
re-enabled.
