Emergency liftgate safety release
ONX4050026
Your vehicle is equipped with the
emergency liftgate safety release lever
located on the bottom of the liftgate.
When someone is inadvertently locked
in the luggage compartment, the liftgate
can be opened by moving the lever in the
direction of the arrow and pushing the
liftgate open.
WARNING
• For emergencies, be fully aware
of the location of the emergency
liftgate safety release lever in the
vehicle and how to open the liftgate
if you are accidentally locked in the
luggage compartment.
• No one should be allowed to occupy
the luggage compartment of the
vehicle at any time. The luggage
compartment is a very dangerous
location in the event of a crash.
• Use the release lever for
emergencies only. Use with extreme
caution, especially while the vehicle
is in motion.
Power liftgate (if equipped)
The power liftgate open/close button
automatically opens and closes the
liftgate.
Before using the power liftgate
The power liftgate operates when the
gear is in P (Park) with the Engine Start/
Stop button in the ON position. However,
the liftgate will operate regardless of the
gear position when the engine is off.
For safety, before attempting to open or
close the liftgate, make sure the vehicle
is in P (Park).
WARNING
• Never leave children unattended
in your vehicle. Children might
operate the power liftgate. Doing so
could result in injury to themselves
or others, and could damage the
vehicle.
• Make sure there are no people or
objects around the liftgate before
operating the power liftgate. Wait
until the liftgate is opened fully and
stopped before loading or unloading
cargo or passengers from the
vehicle.
NOTICE
Do not close or open the power
liftgate manually. This may cause
damage to the power liftgate. If it is
necessary to close or open the power
liftgate manually when the battery is
discharged or disconnected, do not
apply excessive force.

Automatic reverse
ONX4050030
During power opening and closing if the
power liftgate is blocked by an object or
part of the body, the power liftgate will
detect the resistance.
• If the resistance is detected while
opening the liftgate, it will stop and
move in the opposite direction.
• If the resistance is detected while
closing the liftgate, it will stop and
move in the opposite direction.
However, if the resistance is weak such
as from an object that is thin or soft, or
the liftgate is near the latched position,
the automatic stop and reversal may not
detect the resistance. If the automatic
reversal feature operates continuously
more than twice during opening or
closing operation, the power liftgate may
stop at that position. At this time, close
the liftgate manually and operate the
liftgate automatically again.
WARNING
Never intentionally place any object
or part of your body in the path of
the power liftgate to make sure the
automatic reverse function operates.
NOTICE
Do not put heavy objects on the power
liftgate before you operate the power
liftgate. Additional weight may damage
the operation of the system.
Non-operating conditions of the
power liftgate
• The power liftgate does not open
when the vehicle is in motion.
The chime will sound if you drive
over 2mph (3km/h) with the
liftgate opened. Stop your vehicle
immediately at a safe place and check
if your liftgate is opened.
• Operating the power liftgate more
than 5 times continuously could
cause damage to the operating motor.
If this occurs, the power liftgate
system enters into thermal protection
mode to prevent the motor from
overheating. In thermal protection
mode, the power liftgate will not
operate. If any of the power liftgate
buttons are pressed to try to open the
liftgate, the chime will sound 3 times
but the liftgate will not operate.
Allow the power liftgate system
to cool for about 1 minute before
operating the system again.
• The power liftgate can be operated
when the engine is not running.
However the power liftgate operation
consumes large amounts of vehicle
electric power. To prevent the battery
from being discharged, do not
operate it excessively e.g.: more than
approximately 10 times repeatedly.
• To prevent the battery from being
discharged, do not leave the power
liftgate in the open position for a long
lime.
• When jacking up the vehicle to
change a tire or repair the vehicle, do
not operate the power liftgate. This
could cause the power liftgate to
operate improperly.
• In cold and wet climates, the power
liftgate may not work properly due to
freezing conditions.

WARNING
Automotive fuel is highly flammable
and explosive. Failure to follow these
guidelines may result in SERIOUS
INJURY or DEATH:
• Read and follow all warnings posted
at the gas station.
• Before refueling, note the location
of the Emergency Fuel Shut-Off, if
available, at the gas station.
• Before touching the fuel nozzle, you
should eliminate the potential build-
up of static electricity by touching
a metal part of the vehicle, a safe
distance away from the fuel filler
neck, nozzle, or other gas source,
with your bare hand.
• Do not use mobile phones while
refueling. Electric current and/or
electronic interference from cellular
phones can potentially ignite fuel
vapors and cause a fire. •
Do not get back into a vehicle
once you have begun refueling.
You can generate a buildup of
static electricity by touching,
rubbing or sliding against any item
or fabric capable of producing
static electricity. Static electricity
discharge can ignite fuel vapors
causing a fire. If you must re-enter
the vehicle, you should once again
eliminate potentially dangerous
static electricity discharge by
touching a metal part of the vehicle,
away from the fuel filler neck, nozzle
or other fuel source, with your bare
hand.
• When using an approved portable
fuel container, be sure to place the
container on the ground prior to
refueling. Static electricity discharge
from the container can ignite fuel
vapors causing a fire.
Once refueling has begun, contact
between your bare hand and the
vehicle should be maintained until
the filling is complete.
• Use only approved portable plastic
fuel containers designed to carry and
store fuel.
• When refueling, always shift the
gear to the P (Park) position, set
the parking brake, and press the
Engine Start/Stop button to the
OFF position. Sparks produced by
electrical components related to the
engine can ignite fuel vapors causing
a fire.
• Do not use matches or a lighter and
do not smoke or leave a lit cigarette
in your vehicle while at a gas station,
especially during refueling.
• Do not over-fill or top-off your
vehicle tank, which can cause fuel
spillage.
