3-18 Seats and Restraints
To remove and store the comfort
guide, squeeze the belt edges
together so that the safety belt can
be removed from the guide. Slide
the guide onto the storage clip.
Safety Belt Use During
Pregnancy
Safety belts work for everyone,
including pregnant women. Like all
occupants, they are more likely to
be seriously injured if they do not
wear safety belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap
portion should be worn as low as
possible, below the rounding,
throughout the pregnancy.
The best way to protect the fetus is
to protect the mother. When a safety
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making safety
belts effective is wearing them
properly.
Lap Belt (Crew and
Extended Cab)
This section is only for the lap belt.
To learn how to wear a lap-shoulder
belt, seeLap-Shoulder Belt on
page 3‑13. Your vehicle may have a center
seating position. When you sit in the
center front seating position, you
have a lap safety belt, which has no
retractor.
To make the belt longer, tilt the latch
plate and pull it along the belt.
Buckle, position, and release it the
same way as the lap part of a
lap-shoulder belt.

3-30 Seats and Restraints
To turn off the right front passenger
airbag, insert the ignition key into
the switch, push in, and move the
switch to the off position.
The word OFF or the off symbol will
come on in the passenger airbag
status indicator located in the
overhead console to let you know
that the right front passenger airbag
is off, after the system check is
completed. The airbag off light will
come on and stay on to let you
know that the right front passenger's
airbag is off. SeeAirbag On-Off
Light on page 5‑18.{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. For
example, the right front
passenger airbag could inflate
even though the airbag on-off
switch is turned off.
To help avoid injury to yourself or
others, have the vehicle serviced
right away. See Airbag Readiness
Light on page 5‑17 for more
information, including important
safety information.

To turn the right front passenger
airbag on again, insert the ignition
key into the switch, push in, and
move the switch to the on position.
The right front passenger frontal
airbag is now enabled (may inflate).
SeeAirbag On-Off Light on
page 5‑18 for more information.
Passenger Sensing
System
If the vehicle has one of the
indicators pictured in the following
illustrations, then the vehicle has a
passenger sensing system for the
right front passenger position,
unless there is an airbag off switch
located in the glove box. If there is
an airbag off switch, the vehicle
does not have a passenger sensing
system. See Airbag On-Off Switch
on page 3‑28 for more information.
The passenger airbag status
indicator will be visible on the
overhead console when the vehicle
is started. In addition, if the vehicle has a
passenger sensing system for the
right front passenger position, the
label on the vehicle's sun visors
refers to
“ADVANCED AIRBAGS”.United States
Canada and Mexico
The words ON and OFF, or the
symbol for on and off, will be visible
during the system check. If you are
using remote start to start the
vehicle from a distance, if equipped,
you may not see the system check.
When the system check is
complete, either the word ON or OFF, or the symbol for on or off, will
be visible. See
Passenger Airbag
Status Indicator on page 5‑19.
The passenger sensing system will
turn off the right front passenger
frontal airbag under certain
conditions. The driver airbag, seat‐
mounted side impact airbags
(if equipped), and the roof-rail
airbags (if equipped) are not
affected by the passenger sensing
system.
The passenger sensing system
works with sensors that are part of
the right front passenger seat and
safety belt. The sensors are
designed to detect the presence of
a properly-seated occupant and
determine if the right front
passenger frontal airbag should be
enabled (may inflate) or not.
According to accident statistics,
children are safer when properly
secured in a rear seat in the correct
child restraint for their weight
and size.
