Quick Reference Guide
What to Do If
Why do I hear an operating
noise when applying the
brakes?This can occur when the ABS activates and does not indicate a
problem. Apply firm, steady pressure on the brake pedal. Never
pump the brake pedal.
2Anti-lock Brake System (ABS) (P437)
The rear door cannot be
opened from inside the
vehicle. Why?Check if the childproof lock is in
the lock position. If so, open the
rear door with the outside door
handle.
To cancel this function, slide the
lever up to the unlock position.
Why do the doors lock
after I unlocked the doors?If you do not open the doors within 30 seconds, the doors are
relocked automatically for security.
Why does the beeper
sound when I open the
driver’s door?The beeper sounds when:
●The power mode is in ACCESSORY.
●The exterior lights are left on.

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. This 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
holding the release button.
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 be fore driving.Lap belt
as low as
possible
■Adjusting the Shoulder Anchor1Adjusting 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.

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 anchor s 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 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.
• 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. 83
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.

Safe Driving
Safety of Infants and Small Children
An infant must be properly restrained in a rear-facing, reclining child seat until the
infant reaches the seat manufacturer’s weig ht or height limit for the seat, and the
infant is at least one year old.
■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. 54
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
Many experts recommend us e of a rear-facing seat
for a child up to two years old if the child’s height and
weight are appropriate for a rear-facing seat.
Rear-facing child seats should never be installed 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.
