Never attach two child-restraint
systems to the same ISOFIX/LATCH*1
lower anchor:
Attaching two child-restraint systems
to the same ISOFIX/LATCH
*1 lower
anchor is dangerous. In a collision, one
anchor may not be strong enough to
hold two child-restraint system
attachments, and it may break, causing
serious injury or death. If you use the
seat position for another child-restraint
system when an outboard ISOFIX/
LATCH
*1 position is occupied, use the
center seat belts instead, and the
tether if tether-equipped.
Make sure the child-restraint system is
properly secured:
An unsecured child-restraint system is
dangerous. In a sudden stop or a
collision it could move causing serious
injury or death to the child or other
occupants. Follow the child-restraint
system manufacturer's instructions on
belt routing to secure the seat just as
you would with a child in it so that
nobody is tempted to put a child in an
improperly secured seat later on.
When not in use, remove it from the
vehicle or fasten it with a seat belt, or
attach it to BOTH ISOFIX/LATCH
*1
lower anchors for ISOFIX/LATCH*1
child-restraint systems.
Make sure there are no seat belts or
foreign objects near or around the
ISOFIX/LATCH
*1 child-restraint
system:
Not following the child-restraint system
manufacturer's instructions when
installing the child-restraint system is
dangerous. If seat belts or a foreign
object prevent the child-restraint
system from being securely attached to
the ISOFIX/LATCH
*1 lower anchors
and the child-restraint system is
installed improperly, the child-restraint
system could move in a sudden stop or
collision causing serious injury or death
to the child or other occupants. When
installing the child-restraint system,
make sure there are no seat belts or
foreign objects near or around the
ISOFIX/LATCH
*1 lower anchors.
Always follow the child-restraint
system manufacturer's instructions.
*1ISOFIX (Mexico)/LATCH (Except Mexico)
Installation on rear outboard seats
1. First, adjust the front seat to allow clearance between the
child-restraint system and the front
seat.
Refer to Adjusting the Driver's Seat
on page 2-5.
Refer to Adjusting the Front
Passenger's Seat on page 2-13.
2. Make sure the seatback is securely latched by pushing it back until it is
fully locked.

Never use a rear-facing child-restraint
system in the front seat with an air
bag that could deploy:
Rear-facing child-restraint systems on
the front seat are particularly
dangerous even though you may feel
assured that a front passenger air bag
will not deploy based on the fact that
the front passenger air bag
deactivation indicator light illuminates.
The child-restraint system can be hit by
a deploying air bag and moved
violently backward resulting in serious
injury or death to the child.
Do not sit too close to the driver and
front passenger air bags:
Sitting too close to the driver and front
passenger air bag modules or placing
hands or feet on them is extremely
dangerous. The driver and front
passenger air bags inflate with great
force and speed. Serious injuries could
occur if someone is too close. The
driver should always hold onto only the
rim of the steering wheel. The front
seat passenger should keep both feet
on the floor. Front seat occupants
should adjust their seats as far back as
possible and always sit upright against
the seatbacks with seat belts worn
properly.
Sit in the center of the seat and wear
seat belts properly:
Sitting too close to the side air bag
modules or placing hands on them, or
sleeping up against the door or
hanging out the windows is extremely
dangerous. The side and curtain air
bags in flate with great force and speed
directly expanding along the door on
the side the car is hit. Serious injury
could occur if someone is sitting too
close to the door or leaning against a
window, or if rear seat occupants grab
the sides of the front seatbacks. Give
the side and curtain air bags room to
work by sitting in the center of the seat
while the vehicle is moving with seat
belts worn properly.
Do not attach objects on or around
the area where air bags deploy:
Attaching objects to the air bags or
placing something in the area where
the air bags deploy is dangerous. In an
accident, an object could interfere with
air bag in flation and injure the
occupants. Furthermore, the bag could
be damaged causing gases to release.
Always keep the deployment area of
the air bag modules free of any
obstructions.
For example, you should not do any of
the following as it may interfere with
air bag deployment.
 Do not put a covering on or lean
anything against areas such as the
dashboard and lower portion of the
instrument panel that blocks the
passenger front air bag and knee air
bags.
 Do not use seat covers on the front
seats and rear seats equipped with
in-seat side air bags.
 Do not hang any backpacks, bags or
pouches that cover the sides of the
seats that block the side air bags.

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
fi
nd 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, fuel-filler
lid, and 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/trunk lid, always verify that
they are securely closed:
Doors and the liftgate/trunk lid not
securely closed are dangerous, if the
vehicle is driven with a door and the
liftgate/trunk lid not securely closed,
the door and the liftgate/trunk lid
could open unexpectedly resulting in
an accident.
Always con firm the safety around the
vehicle before opening a door and the
liftgate/trunk lid:
Suddenly opening a door and the
liftgate/trunk lid 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/
trunk lid 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/
trunk lid or a passing pedestrian
could be hit, resulting in an
unexpected accident or injury.

WARNING
Never allow a person to ride in the
luggage compartment/trunk:
Allowing a person to ride in the
luggage compartment/trunk is
dangerous. The person in the luggage
compartment/trunk could be seriously
injured or killed during sudden braking
or a collision.
Do not drive with the liftgate/trunk
lid open:
Exhaust gas in the cabin of a vehicle is
dangerous. An open liftgate/trunk lid
in a moving vehicle will cause exhaust
gas to be drawn into the cabin. This
gas contains CO (carbon monoxide),
which is colorless, odorless, and highly
poisonous, and it can cause loss of
consciousness and death. Moreover,
an open liftgate/trunk lid could cause
occupants to fall out in an accident.
Do not stack or leave loaded luggage
unsecured in the luggage
compartment:
Otherwise, the luggage may move or
collapse, resulting in injury or an
accident. In addition, do not load
luggage higher than the seatbacks. It
may a
ffect the side or rear field of view.
Additionally, if the air bags deploy, the
cargo may scatter which could result in
serious injury or death.

Inside Trunk ReleaseLever (4-door)
*
▼Inside Trunk Release Lever
Your vehicle is equipped with an inside
trunk release lever that provides a
means of escape for children and
adults in the event they become locked
inside the trunk.

No matter how careful adults might be
with keys and locking their cars,
parents should be aware that children
may be tempted to play around
vehicles and use the trunk as a hiding
place.

Adults are advised to familiarize
themselves with the operation and
location of the inside trunk release
lever so that all children can be told
about it in an appropriate way, keeping
in mind that most vehicles do not have
such levers.
WARNING
Close the trunk lid, be sure the seat
backs are latched and do not allow
children to play inside the vehicle:
Leaving the trunk lid open or leaving
children in the vehicle with the keys is
dangerous. Children could open the
trunk lid and climb inside resulting in
possible injury or death from heat
exposure.
Always keep the car from being a
tempting place to play by latching the
rear seats, doors and the trunk, and
keeping the keys where children can
not play with them:
Leaving children or animals unattended
in a parked vehicle is dangerous.
Babies left sleeping and children who
lock themselves in cars or trunks can
die very quickly from heat prostration.
Do not leave your children or pets
alone in a car at any time. Do not leave
the car, the rear folding seats or the
trunk unlocked.
▼
Opening the Trunk Lid from the
Inside
Slide the inside trunk release lever in
the direction of the arrow. The lever is
made of material that will glow for
hours in the darkness of the trunk
following a brief exposure to ambient
light.

The inside trunk release lever is located
on the inside of the trunk lid.

The windows can be opened/closed
by operating the power window
switches.
WARNING
Make sure the opening is clear before
closing a window:
Closing a power window is dangerous.
A person's hands, head, or even neck
could be caught by the window and
result in serious injury or even death.
This warning applies especially to
children.
Never allow children to play with
power window switches:
Power window switches that are not
locked with the power window lock
switch would allow children to operate
power windows unintentionally, which
could result in serious injury if a child's
hands, head or neck becomes caught
by the window.
Make sure nothing blocks the window
just before it reaches the fully closed
position or while fully holding up the
power window switch:
Blocking the power window just before
it reaches the fully closed position or
while fully holding up the power
window switch is dangerous.
In this case, the jam-safe function may
not prevent the window from closing
all the way. If
fingers are caught,
serious injuries could occur.
Do not let a child put a hand or head
out of the window while driving the
vehicle:
If the person's hand or head hits
something outside the vehicle, or
sudden braking is applied, it could
result in serious injury or death.
NOTE
When driving with only 1 of the rear
windows open, your ears might
experience a resonating sound.
However, this does not indicate a
problem. The sound can be reduced
by slightly opening a front window or
by changing the size of the rear
window opening.
▼ Opening/Closing Windows
The window opens while the switch is
pressed and it closes while the switch
is pulled up with the ignition switched
ON. Do not open or close 3 or more
windows at the same time.
The front passenger's window and rear
windows can be opened/closed when
the power window lock switch on the
driver's door is in the unlocked
position. Keep this switch in the locked
position while children are in the
vehicle.

Moonroof*
▼Moonroof
The moonroof can be opened or
closed when operating the overhead
tilt/slide switch at the front seats.
WARNING
Do not let passengers stand up or
extend part of the body through the
open moonroof while the vehicle is
moving:
Extending the head, arms, or other
parts of the body through the
moonroof is dangerous. The head or
arms could hit something while the
vehicle is moving. This could cause
serious injury or death.
Never allow children to play with the
tilt/slide switch:
The tilt/slide switch would allow
children to operate the moonroof
unintentionally, which could result in
serious injury if a child's hands, head
or neck becomes caught by the
moonroof.
Make sure the opening is clear before
closing the moonroof:
A closing moonroof is dangerous. The
hands, head, or even neck of a person,
especially a child, could be caught in it
as it closes, causing serious injury or
even death.
Make sure nothing blocks the
moonroof just before it reaches the
fully closed position:
Blocking the moonroof just before it
reaches the closed position is
dangerous.
In this case, the jam-safe function
cannot prevent the moonroof from
closing. If
fingers are caught, serious
injuries could occur.
CAUTION
 Do not sit on or put heavy items on
the area where the moonroof opens
and closes. Otherwise, the
moonroof could be damaged.
 Do not open or close the moonroof
forcefully during freezing
temperatures or snowfall. Otherwise,
the moonroof could be damaged.
 The sunshade does not tilt. To avoid
damaging the sunshade, do not push
it up.
 Do not close the sunshade while the
moonroof is opening. Trying to force
the sunshade closed could damage
it.
