Fastening a Seat Belt
After adjusting a front seat to the proper position, and while sitting upright and well
back in the seat:
2 Seats P. 198
1.Pull the seat belt out slowly.
2. Insert the latch plate into the buckle, then
tug on the belt to make sure the buckle is
secure.
u Make sure that the belt is not twisted or
caught on anything.
1Fastening a Seat Belt
No one should sit in a seat with an inoperative seat
belt or one that does not appear to be working
correctly. Using a seat be lt that is not working
properly may not protect the occupant in a crash.
Have a dealer check the belt as soon as possible.
Never insert any foreign obj ects into the buckle or
retractor mechanism.
If the seat belt appears to be locked in a fully
retracted position, firmly pull out on the shoulder belt
once, then push it back in.
Then, smoothly pull it out of the retractor and fasten.
If you are unable to release the seat belt from a fully
retracted position, do not allow anyone to sit in the
seat, and take your vehicle to a dealer for repair.

3. Position the lap part of the belt as low as
possible across your hips, then pull up on
the shoulder part of the belt so the lap part
fits snugly. Th is lets your strong pelvic
bones take the force of a crash and reduces
the chance of internal injuries.
4. If necessary, pull up on the belt again to
remove any slack, then check that the belt
rests across the center of your chest and
over your shoulder. Th is spreads the forces
of a crash over the strongest bones in your
upper body.
The front seats have adjustable shoulder anchors to accommodate taller and shorter
occupants. 1.Move the anchor up and down while
holding the release button.
2. Position the anchor so that the belt rests
across the center of your chest and over
your shoulder.1Fastening a Seat Belt
To release the belt, push the red PRESS button and
then guide the belt by hand until it has retracted
completely.
When exiting the vehicle, be sure the belt is properly
stowed so that it will not get caught in the closing door.
3WARNING
Improperly positioning the seat belts can
cause serious injury or death in a crash.
Make sure all seat belts are properly
positioned be fore driving.Lap belt

■Adjusting the Shoulder Anchor1Adjusting the Shoulder Anchor

Safe Driving
• Never hold a child on your lap because it is impossible to protect them in the
event of a collision.
• Never put a seat belt over yourself and a child. During a crash, the belt would
likely press deep into the child an d cause serious or fatal injuries.
• Never let two children use the same seat belt. Both children could be very
seriously injured in a crash.
• Any child who is too small to wear a seat belt correctly must be restrained in an
approved child seat that is properly secu red to the vehicle using either the seat
belt or the lower anchor s of the LATCH system.
• Do not allow children to operate the doors, windows or seat adjustments.
• Do not leave children in the vehicle unattended, especially in hot weather when
the inside of the vehicle can get hot enough to kill them. They could also activate
vehicle controls causing it to move unexpectedly.1 Protecting Child Passengers
To deactivate a lockable retractor, release the buckle
and allow the seat belt to wind up all the way.
To remind you of the pa ssenger’s front airbag
hazards and child safety, your vehicle has warning
labels on the dashboard (U.S. models) and on the
front visors. Please read and follow the instructions
on these labels. 2 Safety Labels P. 85
3WARNING
Allowing a child to play with a seat belt or
wrap one around their neck can result in
serious injury or death.
Instruct children not to play with any seat
belt and make sure any unused seat belt a
child can reach is buckled, fully retracted,
and locked.

Safety of Infants and Small Children
An infant must be properly restrained in a rear-facing child seat until the infant
reaches the seat manufacturer’s weight or height limit for the seat.
■Positioning a rear-facing child seat
Child seats must be placed and secured in a
rear seating position.
When properly installed, a rear-facing chil d seat may prevent the driver or a front
passenger from moving their seat all the wa y back, or from locking their seat-back
in the desired position. Make sure that there is no contact between the child seat
and the seat in front of it.
It can also interfere with proper operation of the passenger’s advanced front airbag
system.
2 Airbags P. 51
If this occurs, we recommend that you insta ll the child seat directly behind the front
passenger’s seat, move the seat as far fo rward as needed, and leave it unoccupied.
Or, you may wish to get a smaller rear-facing child seat.
■Protecting Infants1 Protecting Infants
Experts recommend use of a rear-facing seat for a
child so long as the child’ s height and weight are
appropriate for a rear facing seat.
Infants should never be s eated in a forward facing
position.
Always refer to the child seat manufacturer’s
instructions before installation.
Do not allow a front seat to rest against a child seat
installed in a rear seating position.
The weight sensor in the fr ont seat may not correctly
detect the actual weight of the occupant.
3WARNING
Placing a rear-facing child seat in the front
seat can result in serious injury or death
during a crash.
Always place a rear-fac ing child seat in the
rear seat, not the front.

Safe DrivingIf a child has exceeded the weight and heig ht limitations of a rearward-facing child
seat, the child should be properly restrained in a firmly secured forward-facing child
seat until they exceed the weight and height limitations for the forward-facing child
seat.
■Forward-facing child seat placement
We strongly recommend placing a forward-
facing child seat in a rear seating position.
Placing a forward-facing child seat in the front seat can be hazardous, even with
advanced front airbags that automatically turn the passenger’s front airbag off. A
rear seat is the safest place for a child.
■Protecting Smaller Children1 Protecting Smaller Children
Educate yourself about th e laws and regulations
regarding child seat use wh ere you are driving, and
follow the child seat manufacturer’s instructions.
3WARNING
Placing a forward-facing child seat in the
front seat can result in serious injury or
death if the front airbag inflates.
If you must place a forward-facing child
seat in front, move the vehicle seat as far
back as possible, and properly restrain the
child.
