WARNING
When you return the rear seatback to
its upright position after being folded
down:
Be careful not to damage the seat belt
webbing or buckle. Do not allow the
seat belt webbing or buckle to get
caught or pinched in the rear seat.
Ensure that the seatback is completely
locked into its upright position by
pushing on the top of the seatback.
Otherwise, in an accident or sudden
stop, the seat could fold down and
allow cargo to enter the passenger
compartment, which could result in
serious injury or death.
NOTICE

[When returning the rear seatbacks
to the upright position, remember to
return the rear shoulder belts to their
proper position.

[Routing the seat belt webbing
through the rear seat belt guides will
help keep the seat belts from being
trapped behind or under the seats.
WARNING
Cargo
Cargo should always be secured to
prevent it from being thrown about the
vehicle in a collision and causing injury
to the vehicle occupants. Do not place
objects in the rear seats, since they
cannot be properly secured and may hit
the front seat occupants in a collision.
WARNING
Cargo loading
Make sure the engine is off, the
Automatic transmission/Dual clutch
transmission is in N (Neutral) or the
Manual transmission is in R (Reverse)
or the 1st gear, and the parking brake is
securely applied whenever loading or
unloading cargo. Failure to take these
steps may allow the vehicle to move if
the shift lever is inadvertently moved to
another position.

the vehicle is moving.
WARNING
Do not leave children or animals
unattended in your vehicle. An enclosed
vehicle can become extremely hot,
causing death or serious injury to
unattended children or animals who
cannot escape the vehicle.
Children might operate features of the
vehicle that could injure them, or they
could encounter other harm, possibly
from someone gaining entry to the
vehicle.
WARNING
Always secure your vehicle
Leaving your vehicle unlocked can
allow theft or entry into the vehicle.
To secure your vehicle, whilst
depressing the brake, move the shift
lever to the N (Neutral) position (for
Automatic transmission/Dual clutch
transmission) or the first gear or R
(Reverse, for Manual transmission),
engage the parking brake, and place

position, close all windows, lock all
doors, and always take the key with
you.
WARNING
If you stay in the vehicle for a long time
whilst the weather is very hot or cold,
there are risks of injuries or danger to
life. Do not lock the vehicle from the
outside when someone is in the vehicle.
WARNING
Opening a door when something is
approaching may cause damage or
injury. Be careful when opening doors
and watch for vehicles, motorcycles,
bicycles or pedestrians approaching
the vehicle in the path of the door.
Deadlocks (if equipped)
Some vehicles are equipped with a
deadlock system. Deadlocks prevent
opening of a door from either inside
or outside the vehicle once the dead-
locks have been activated providing
an additional measure of vehicle
security.
To lock the vehicle using the dead-
lock function, the doors must be
locked by using the remote key or
smart key. To unlock the vehicle, the
transmitter or smart key must be used
again.
WARNING
Do not lock the doors with the
remote key or the smart key with
anybody left in the vehicle. The
passenger in the vehicle cannot
unlock the doors with the door
lock button. For example, if the
door is locked with the remote key,
the passenger in the vehicle can-
not unlock the door without the
transmitter.

[Do not get back into a vehicle
once you have begun refuelling.
You can generate a build-up of
static electricity by touching,
rubbing or sliding against any item
or fabric capable of producing
static electricity. Static electricity
discharge can ignite fuel vapours
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 petrol source, with your bare
hand.

[When refuelling, always move the
shift lever to the N (Neutral, for
Automatic transmission/Dual clutch
transmission) or the first gear or R
(Reverse, for Manual transmission)
position, set the parking brake,
and place the ignition switch to the

by electrical components related to
the engine can ignite fuel vapours
causing a fire.

[When using an approved portable
fuel container, be sure to place
the container on the ground prior
to refuelling. Static electricity
discharge from the container can
ignite fuel vapours causing a fire.
Once refuelling 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 petrol.
[Do not use matches or a lighter and
do not smoke or leave a lit cigarette
in your vehicle whilst at a gas station,
especially during refuelling.

[Do not over-fill or top-off your
vehicle tank, which can cause petrol
spillage.

[If a fire breaks out during refuelling,
leave the vicinity of the vehicle, and
immediately contact the manager
of the gas station and then contact
WKHORFDOILUHGHSDUWPHQW)ROORZDQ\
safety instructions they provide.

[If pressurized fuel sprays out, it can
cover your clothes or skin and thus
subject you to the risk of fire and
burns. Always remove the fuel cap
carefully and slowly. If the cap is
venting fuel or if you hear a hissing
sound, wait until the condition stops
before completely removing the cap.

[Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident.

IGNITION SWITCH
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, whilst 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.
Key ignition switch (if equipped)
OIB054010
WARNING

[NEVER turn the ignition switch to
the LOCK or ACC position whilst
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 lever
is in the 1st gear when the vehicle
is parked on an uphill and in
R(Reverse) on a downhill (for manual
transmission vehicle), or P (Park, for
automatic transmission/dual clutch
transmission vehicle) position, apply
the parking brake, and turn the
ignition switch to the LOCK position.
Unexpected vehicle movement may
occur if these precautions are not
followed.
NOTICE
Never use aftermarket keyhole covers.
This may generate start-up failure due
to communication failure.
