Shoulder Belt Height Adjuster
The vehicle has a shoulder belt height adjuster for the
driver and right front passenger position.
Adjust the height so that the shoulder portion of the belt
is centered on the shoulder. The belt should be away
from the face and neck, but not falling off the shoulder.
Improper shoulder belt height adjustment could
reduce the effectiveness of the safety belt in a crash.
Press the release
button (A) and move
the height adjuster to
the desired position. The
adjuster can be moved
up by pushing up on
the shoulder belt guide.
After the adjuster is set to the desired position, try to
move it down without pressing the release button
to make sure it has locked into position.
Safety Belt Pretensioners
This vehicle has safety belt pretensioners for front
outboard occupants. Although the safety belt
pretensioners cannot be seen, they are part of the safety
belt assembly. They can help tighten the safety belts
during the early stages of a moderate to severe frontal
or near frontal crash if the threshold conditions for
pretensioner activation are met. And, if your vehicle
has side impact airbags, safety belt pretensioners can
help tighten the safety belts in a side crash.
Pretensioners work only once. If the pretensioners
activate in a crash, they will need to be replaced, and
probably other new parts for the vehicle’s safety
belt system. SeeReplacing Restraint System Parts
After a Crash on page 1-71.
Rear Safety Belt Comfort Guides
Rear shoulder belt comfort guides may provide added
safety belt comfort for older children who have outgrown
booster seats and for some adults. When installed on
a shoulder belt, the comfort guide better positions
the belt away from the neck and head.

Securing a Child Restraint in the
Right Front Seat Position
This vehicle has airbags. A rear seat is a safer place to
secure a forward-facing child restraint. SeeWhere to
Put the Restraint on page 1-42.
In addition, the vehicle has a passenger sensing system
which is designed to turn off the right front passenger
frontal airbag and seat-mounted side impact airbag
under certain conditions. SeePassenger Sensing
System on page 1-64andPassenger Airbag Status
Indicator on page 3-55for more information, including
important safety information.
A label on the sun visor says, “Never put a rear-facing
child seat in the front.” This is because the risk to
the rear-facing child is so great, if the airbag deploys.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front passenger
airbag inates. This is because the back of the
rear-facing child restraint would be very close to the
inating airbag. A child in a forward-facing child
restraint can be seriously injured or killed if the right
front passenger airbag inates and the passenger
seat is in a forward position.
Even if the passenger sensing system has turned
off the right front passenger frontal airbag, no
system is fail-safe. No one can guarantee that
an airbag will not deploy under some unusual
circumstance, even though it is turned off.
Secure rear-facing child restraints in a rear
seat, even if the airbag is off. If you secure a
forward-facing child restraint in the right front seat,
always move the front passenger seat as far back
as it will go. It is better to secure the child restraint
in a rear seat.
SeePassenger Sensing System on page 1-64for
additional information.
1-52

Passenger Sensing System
The vehicle has a passenger sensing system for the
right front passenger position. The passenger airbag
status indicator will be visible on the overhead console
when the vehicle is started.
The words ON and OFF, or the symbol for on and off,
are visible during the system check. If you are using
remote start, if equipped, to start the vehicle from
a distance, 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.
SeePassenger Airbag Status Indicator on page 3-55.The passenger sensing system turns off the right front
passenger frontal airbag and seat-mounted side
impact airbag under certain conditions. The driver
airbags and the roof-rail airbags are not affected by the
passenger sensing system.
The passenger sensing system works with sensors that
are part of the right front passenger seat. The sensors
are designed to detect the presence of a properly-seated
occupant and determine if the right front passenger
frontal airbag and seat-mounted side impact airbag
should be enabled (may inate) 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.
We recommend that children be secured in a rear seat,
including: an infant or a child riding in a rear-facing
child restraint; a child riding in a forward-facing child
seat; an older child riding in a booster seat; and children,
who are large enough, using safety belts.
A label on the sun visor says, “Never put a rear-facing
child seat in the front.” This is because the risk to
the rear-facing child is so great, if the airbag deploys. United States

R (Reverse):Use this gear to back up.
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
Also use this gear to rock the vehicle back and forth to
get out of snow, ice or sand without damaging the
transmission. SeeIf Your Vehicle is Stuck in Sand, Mud,
Ice, or Snow on page 4-18for additional information.
N (Neutral):In this position, the engine does not
connect with the wheels. To restart when you are
already moving, use N (Neutral) only. Also, use
N (Neutral) when the vehicle is being towed.
{CAUTION:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is rmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.Notice:Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage
the transmission. The repairs would not be covered
by the vehicle warranty. Be sure the engine is
not running at high speed when shifting the vehicle.
D (Drive):This position is for normal driving. It provides
the best fuel economy for the vehicle. If you need
more power for passing, and you are:
Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
The transmission will shift down to the next gear and
have more power.
Downshifting the transmission in slippery road conditions
could result in skidding, see Skidding underLoss of
Control on page 4-10.
2-30

Notice:Driving the vehicle if you notice that it is
moving slowly or not shifting gears as you increase
speed may damage the transmission. Have the
vehicle serviced right away. You can drive in
2 (Second) when you are driving less than 35 mph
(55 km/h) and D (Drive) for higher speeds until then.
D (Drive) can be used for towing. You may want to
shift the transmission to 3 (Third) or, if necessary, to a
lower gear if the transmission shifts too often under
heavy loads and/or hilly conditions.
SeeTowing a Trailer on page 4-28for more information.
3 (Third):This position is also used for normal
driving. However, it reduces vehicle speed more than
D (Drive) without using the brakes. You might choose
3 (Third) instead of D (Drive) when driving on hilly,
winding roads, when towing a trailer, so there is less
shifting between gears and when going down a
steep hill.2 (Second):This position reduces vehicle speed more
than 3 (Third) without using the brakes. You can use
2 (Second) on hills. It can help control vehicle speed
as you go down steep mountain roads, but then
you would also want to use the brakes off and on.
Notice:Do not shift into 2 (Second) unless you are
going slower than 65 mph (105 km/h), or you can
damage the engine and/or transmission.
1 (First):This position reduces vehicle speed even
more than 2 (Second) without using the brakes. You can
use it on very steep hills, or in deep snow or mud.
If the shift lever is put in 1 (First) while the vehicle is
moving forward, the transmission will not shift into rst
gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle
in one place on a hill using only the accelerator
pedal may damage the transmission. The repair will
not be covered by the vehicle warranty. If you are
stuck, do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.

When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporary
condition, the message PARK ASSIST OFF will be
displayed on the DIC and a red light will be shown on
the rear URPA display when the shift lever is moved into
R (Reverse). This occurs under the following conditions:
The driver disables the system.
The ultrasonic sensors are not clean. Keep the
vehicle’s rear bumper free of mud, dirt, snow,
ice and slush. For cleaning instructions, see
Washing Your Vehicle on page 5-90.
A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the trunk during the
last drive cycle, the red light may illuminate in
the rear display. Once the attached object is
removed, URPA will return to normal operation.
A tow bar is attached to the vehicle.
The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled after driving forward at
least 15 mph (25 km/h), take the vehicle to your
dealer/retailer.
