WARNING AND INDICATOR LIGHTS

PREGNANT WOMEN
INFINITI recommends that pregnant women
use seat belts. The seat belt should be worn
snug, and always position the lap belt as low
as possible around the hips, not the waist,
and place the shoulder belt over your
shoulder and across your chest. Never run
the lap/shoulder belt over your abdominal
area. Contact your doctor for specific re-
commendations.
INJURED PERSONS
INFINITI recommends that injured persons
use seat belts, depending on the injury.
Check with your doctor for specific recom-
mendations.
PRE-CRASH SEAT BELTS WITH
COMFORT FUNCTION (if so
equipped for front seats)
The pre-crash seat belt tightens the seat belt
with a motor to help restrain front seat
occupants. This helps reduce the risk of
injury in a collision.
The motor retracts the seat belt under the
following emergency conditions:
.During emergency braking
. During sudden steering maneuvers
. Activation of the Forward Emergency
Braking (FEB) with pedestrian detection system. (See “Forward Emergency Brak-
ing (FEB) with pedestrian detection”
(P.5-95).)
. In the event of a high severity rollover
collision.
The pre-crash seat belt will not be active
when:
. the seat belt is not fastened
. the vehicle speed is under 10 MPH (15
km/h) during emergency braking
. the vehicle speed is under 19 MPH (30
km/h) during sudden steering maneuvers
or in the event of a high severity rollover
collision.
The pre-crash seat belt will not be active
when the brake pedal is not depressed
except when sudden steering maneuvers
occur or the Forward Emergency Braking
(FEB) with pedestrian detection system
activates.
The motor also retracts the seat belt when
the seat belt is fastened or unfastened.
When the seat belt is fastened, the motor
tightens the seat belt for a snug fit. When
the seat belt is unfastened, the motor
retracts the seat belt. If the seat belt is not
fully retracted, the motor retracts the seat
belt when the door is opened.
Always wear your seat belt correctly and sit
upright and well back. If the motor cannot retract the seat belt
when the seat belt is fastened or unfas-
tened, it may indicate the pre-crash seat belt
system has a malfunction. Have the system
checked and repaired. It is recommended you
visit an INFINITI retailer for this service.
When the seat belt is retracted repeatedly in
a short period of time, the motor may not be
able to retract the seat belt. After 8 minutes,
the motor reactivates and retracts the seat
belt. If the seat belt still cannot be retracted
by the motor, the pre-crash seat belt system
has a malfunction. Have the system checked
and repaired. It is recommended you visit an
INFINITI retailer for this service.
THREE-POINT TYPE SEAT BELT
WARNING
.
Every person who drives or rides in
this vehicle should use a seat belt at
all times.
. Do not ride in a moving vehicle when
the seatback is reclined. This can be
dangerous. The shoulder belt will not
be against your body. In an accident,
you could be thrown into it and
receive neck or other serious injuries.
You could also slide under the lap belt
and receive serious internal injuries.
