Information
If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break the
ice and release the door. Do not pry on the
door. If necessary, spray around the door
with an approved deicer fluid (do not use
radiator antifreeze) or move the vehicle to a warm place and allow the ice to melt. Closing the fuel filler door
1. To install the fuel tank cap, turn it clockwise until it “clicks” one time.
2. Close the fuel filler door until it is latched securely.
WARNING
Gasoline 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 Gasoline 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 cellular 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 gasoline 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 gasoline.
• When refueling, always move the
shift button to the P (Park) position
set the parking brake, and place
the ignition switch to the LOCK/
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 gasoline spillage.

à Press the moving forward/backward
button again after checking the
distance from the vehicles if the
vehicle didn’t move after pressing
and holding the smart key button for about 5 seconds.

à Under cold weather, take enough time
before pressing the moving forward/
backward button of the smart key
after turning on the vehicle remotely.
It may take more time until the vehicle
moves.

à When Remote Moving Forward is
ready by the above No. (1) method,
the vehicle recognizes the condition
as exit. After confirming the
surroundings within 4 m (13 ft.), it
allows to operate the steering wheel
up to the conditions ahead.

à When Remote Moving Forward is
ready by the above No. (2) method,
the vehicle recognizes the condition
as entering to the parking space.
According to the front condition, it
immediately allows the vehicle to
enter to the parking space and line
up with the steering wheel control.
However, the function performance
can be degraded up to the shape or
position of the surrounding objects.

à If you select the remote moving
backward, both of the No. (1) and (2)
methods make the vehicle go straight
after lining up.

à While Remote Moving Forward/
Backward assist is operating, the
brake light turns on.
ODN8A059249
3. Remote Moving Forward/Backward Complete
When the vehicle reaches the desired position, Remote Moving Forward/
Backward is completed as follows:
(1) If the driver enters the vehicle with the smart key, Remote Moving
Forward/Backward is completed. In
this case, the vehicle stays on.
(2) If the driver pushes Remote control button of the smart key, Remote
Moving Forward/Backward is
completed. In this case, the vehicle
stays off.

à The parking complete sound (frequent
beep) is generated.

à When the Remote Moving Forward/
Backward assist is complete, the
gear in P (Park) and Electronic
Parking Brake (EPB) are engaged
automatically.
WARNING
Always be careful of unexpected
approach of the other vehicles or
pedestrians during operation.
While the remote moving forward
function works, the vehicle is controlled
by the steering wheel control so that
the obstacles in the blind spots cannot
be detected.
Always check for obstacles around your
vehicle to prevent the accidents.

Key Ignition Switch (if equipped)
WARNING
To reduce the risk of SERIOUS INJURY or
DEATH, take the following precautions: • NEVER allow children or any person
who is unfamiliar with the vehicle to
touch the ignition switch or related
parts. Unexpected and sudden
vehicle movement can occur.
• NEVER reach through the steering
wheel for the ignition switch, or any
other control, while the vehicle is in
motion. The presence of your hand
or arm in this area may cause a loss
of vehicle control resulting in an
accident.
OAE056172L
Whenever the front door is opened, the
ignition switch will illuminate, provided
the ignition switch is not in the ON
position. The light will go off immediately
when the ignition switch is turned on or
go off after about 30 seconds when the door is closed. (if equipped)
WARNING
NEVER turn the ignition switch to the
LOCK or ACC position while the vehicle
is in motion except in an emergency.
This will result in the engine turning
off and loss of power assist for the
steering and brake systems. This may
lead to loss of directional control and
braking function, which could cause an
accident.
Before leaving the driver's seat, always
make sure the shift button is in P (Park)
position, apply the parking brake,
and turn ignition switch to the LOCK position.
Unexpected vehicle movement may
occur if these precautions are not
followed.
