Fastening a Seat Belt
After adjusting a front seat to the proper position, and while sitting upright and well
back in the seat:
2 Adjusting the Seats P. 193
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.
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 al low anyone to sit in the
seat, and take your vehicle to a dealer for repair.

uuSeat Belts uFastening a Seat Belt
Safe Driving
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. This 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 adjustab le shoulder anchors to accommodate taller and shorter
occupants. 1.Move the anchor up and down while
pulling the shoulder anchor outward.
2. Position the anchor so that the belt rests
across the center of your chest and over
your shoulder.1 Fastening 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 before driving.Lap belt

possible
■Adjusting the Shoulder Anchor1 Adjusting the Shoulder Anchor
The shoulder anchor height can be adjusted to four
levels. If the belt contacts your neck, lower the height
one level at a time.
After an adjustment, make sure that the shoulder
anchor position is secure.

uuChild Safety uProtecting Child Passengers
Safe Driving
• 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 anchors of the LATCH system.
• 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 and cause serious or fatal injuries.
• Never let two children use the same seat belt. Both children could be very
seriously injured in a crash.
• Do not allow children to operate the doors, windows or seat adjustments.
• Do not leave children in the vehicle unatte nded, 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. 80
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.

uuChild Safety uSafety of Infants and Small Children
Safe Driving
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 weig ht 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 child seat may prevent the driver or a front
passenger from moving their seat all the way back, or from locking their seat-back
in the desired position. Make sure that th ere is no contact between the child seat
and the seat in front of it.
It can also interfere with pr oper operation of the passenger’s advanced front airbag
system.
2 Airbags P. 48
If this occurs, we recommend that you install 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 sm aller rear-facing child seat.
■Protecting Infants1Protecting Infants
Experts recommend use of a rear-facing seat for a
child for so long as the chil d’s height and weight are
appropriate for a rear-facing seat.
Always refer to the child seat manufacturer’s
instructions before installation.
Infants never should be s eated in a forward-facing
position.
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.
