When moving the seats forward and rearward or returning a rear-reclined seatback to its
upright position, make sure you hold onto the seatback with your hand while operating. If
the seatback is not held, the seat will move suddenly and could cause injury.
 When inserting your hand under the seat to clean the cabin or pick up something you
dropped under the seat, be careful not to hurt yourself. If you contact the moving parts of
the seat rail or seat frame, it could result in injury.
NOTE
When returning a rear seat to its original position, place the seat belt in its normal
position. Verify that the seat belt pulls out and retracts.
(Power Seat)
The seat-bottom power adjustment is operated by motors. Avoid extended operation
because excessive use can damage the motors.
To prevent the battery from running down, avoid using the power adjustment when the
engine is stopped. The adjuster uses a large amount of electrical power.
Do not use the switch to make more than one adjustment at a time.
When getting in and out of the vehicle, your foot could accidentally contact the seat height
adjustment lever and cause the seat to lower.
Adjust the seat to obtain the correct driving position.

Door Locks
WARNING
Always take all children and pets with you
or leave a responsible person with them:
Leaving a child or a pet unattended in a
parked vehicle is dangerous. In hot
weather, temperatures inside a vehicle can
become high enough to cause brain
damage or even death.
Do not leave the key in your vehicle with
children and keep them in a place where
your children will not find or play with
them:
Leaving children in a vehicle with the key is
dangerous. This could result in someone
being badly injured or even killed.
Keep all doors locked when driving:
Unlocked doors in a moving vehicle are
dangerous. Passengers can fall out if a
door is accidentally opened and can more
easily be thrown out in an accident.
Always close all the windows and
moonroof, lock the doors and the liftgate
and take the key with you when leaving
your vehicle unattended:
Leaving your vehicle unlocked is dangerous
as children could lock themselves in a hot
vehicle, which could result in death. Also, a
vehicle left unlocked becomes an easy
target for thieves and intruders.
After closing the doors and the liftgate,
always verify that they are securely closed:
Doors and the liftgate not securely closed
are dangerous, if the vehicle is driven with
a door and the liftgate not securely closed,
the door and the liftgate could open
unexpectedly resulting in an accident.
Always confirm the safety around the
vehicle before opening a door and the
liftgate:
Suddenly opening a door and the liftgate is
dangerous. A passing vehicle or a
pedestrian could be hit and cause an
accident.
CAUTION
 Always confirm the conditions around
the vehicle before opening/closing the
doors and the liftgate and use caution
during strong winds or when parked on
an incline. Not being aware of the
conditions around the vehicle is
dangerous because fingers could get
caught in the door and the liftgate or a
passing pedestrian could be hit, resulting
in an unexpected accident or injury.
NOTE
Always stop the engine and lock the
doors. In addition, to prevent theft of
valuables, do not leave them inside the
cabin.
If the key is left in the following areas
and you leave the vehicle, the doors may
be locked depending on the radio wave
conditions even if the key is left in the
vehicle.

Be careful when opening/closing the
liftgate during strong winds. If a strong
gust blows against the liftgate, it could
close suddenly resulting in injury.
 Fully open the liftgate and make sure
that it stays open. If the liftgate is only
opened partially, it could slam shut by
vibration or wind gusts resulting in
injury.
 When loading or unloading luggage in
the luggage compartment, turn off the
engine. Otherwise, you could get burned
by the heat of the exhaust gas.
 Be careful not to apply excessive force to
the damper stay on the liftgate such as
by putting your hand on the stay.
Otherwise, the damper stay may bend
and
affect the liftgate operation.
Damper stay
