Top Strap Anchor Location
Right Front Passenger Position Top
Strap Anchor (Regular and Extended
Models)
If your vehicle is a crew cab model, a child restraint with
a top strap should only be used in the second row.
Do not use a child restraint with a top strap in the right
front passenger position because there is no place
to anchor the top strap.For regular and extended cab models, you will ®nd the
top strap anchor for the right front passenger seat behind
the seat, near the ¯oor.
If your vehicle is a regular cab model, there is also a
top strap anchor for the right front passenger position
located on the back panel of your vehicle, behind
the right front passenger seat. In order to get to the
anchor, you'll have to remove the trim plug covering it.
1-45

In order to get to the brackets, you'll have to remove the
trim plugs covering them.
There are also anchorage points at the rear base of the
front passenger's seat.
Lower Anchorages and Top Tethers
for Children (LATCH System)
Your vehicle has the LATCH system. You will ®nd
anchors (A) for the front passenger and the center rear
seating positions for extended cab models. For
regular cab models, you will ®nd anchors for the right
front passenger seating position. For crew cab models,
you will ®nd anchors for the second row center and
second row right passenger seating positions.
This system, designed to make installation of child
restraints easier, does not use the vehicle's safety belts.
Instead, it uses vehicle anchors (A, B) and child
restraint attachments to secure the restraints. Some
restraints also use another vehicle anchor to secure a
top tether strap (C).

In many crashes severe enough to in¯ate the air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.
·Air bags are designed to in¯ate only once. After
they in¯ate, you will need some new parts for
your air bag system. If you do not get them, the air
bag system will not be there to help protect you
in another crash. A new system will include air bag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
·Your vehicle is equipped with electronic frontal
sensors which help the sensing system distinguish
between a moderate and a more severe frontal
impact. Your vehicle is also equipped with a crash
sensing and diagnostic module, which records
information about the frontal air bag system. The
module records information about the readiness of
the system and when the system commands air
bag in¯ation. It records the status of the driver's
safety belt usage in a crash in which the air
bag deploys or a crash in which the air bag nearly
deploys. The module also records speed, engine
rpm, brake and throttle data.
·Let only quali®ed technicians work on your air bag
systems. Improper service can mean that an air
bag system will not work properly. See your dealer
for service.
Notice:If you damage the covering for the driver's
or the right front passenger's air bag, the bag
may not work properly. You may have to replace the
air bag module in the steering wheel or both the
air bag module and the instrument panel for
the right front passenger's air bag. Do not open or
break the air bag coverings.
Air Bag Off Switch
Regular Cab and Extended Cab Models
If your vehicle is a regular cab model or an extended cab
model, it has a switch on the instrument panel that you
can use to turn off the right front passenger's air bag.

this feature. When locking the doors with the power lock
switch or the keyless entry transmitter and a door or the

greater than 8 mph (13 km/h). This is the mode that is
pre-programmed in the factory for manual transmission
vehicles.
Mode 3:No automatic door locking.

You can choose among four driving settings:
h(2HI):This setting is used for driving in most street
and highway situations. Your front axle is not engaged
in two- wheel drive. This setting also provides the
best fuel economy.AUTO 4WD:This setting is ideal for use when road
conditions are variable. When driving your vehicle
in AUTO 4WD, the front axle is engaged, but the
vehicle's power is sent to the rear wheels. When the
vehicle senses a loss of traction, the system will
automatically engage four-wheel drive. Driving in this
mode results in slightly lower fuel economy than 2HI.
G(4HI):Use 4HI when you need extra traction, such
a on snowy or icy roads or in most off-road situations.
This setting also engages your front axle to help
drive your vehicle. This is the best setting to use when
plowing snow.
g(4LO):This setting also engages your front axle
and delivers extra torque. You may never need 4LO. It
sends maximum power to all four wheels. You might
choose 4LO if you are driving off-road in deep
sand, deep mud, deep snow and climbing or descending
steep hills.
