Obstacle Detection Features
If the hood encounters an obstacle during a
power open or close cycle, the hood will
automatically reverse direction and move a
short distance away from the obstacle. After
removing the obstruction, the power hood
operation can be used again.
If the vehicle is locked while the hood is
closing and an obstacle is encountered that
prevents the hood from completely closing,
the horn will sound an alert that the hood
did not close.
Falling Hood Detection
If the power hood encounters excess weight
or a possible mechanical failure, a repetitive
chime will sound and the hood will close
automatically after a power opening cycle.
Interfering with the power hood motion or
manually closing the hood too quickly may
activate the falling hood detection feature.
Allow the hood to complete its operation
and wait a few seconds before manually
closing the hood.
If the hood continues to automatically close
after opening, see your dealer for service
before using the power hood.
Operating the Hood when there is no
Electrical Power
The manual release cable should only be
used for service and/or emergency use, such
as loss of vehicle electrical power. Do not
store any cargo in the area near the hood
release cable.
To open the hood:
1. Firmly pull the hood release cable twice
to release the hood. It is on the lower
left side of the instrument panel.
3. Go to the front of the vehicle and lift
the hood to the desired height.
To close the hood:
1. Before closing the hood, make sure all
cargo is properly stowed and does not
go above or across the hood seal.
2. Pull the hood down until it is secured in
the latch.
3. Check to make sure the hood is latched
completely. Push down on the hood to
latch if it does not latch completely.
Repeat this step with additional force if
necessary.
When the hood is not latched, a message
will display on the Driver Information Center
(DIC) and the vehicle will not be able to
shift out of park. To override this function,
press and hold the shift button and brake
pedal until the DIC message shifter unlock
complete is displayed. The vehicle s speed
will be limited to 42 km/h (26 mph) when
the hood is not completely closed.
If the vehicle has lost power, and the hood
is open when the power is restored, the
power hood and power closing latch will not
operate. To allow powered hood operation
again, the hood must be manually closed
and fully latched.
