{WARNING
Never do this.
Children who are up against,
or very close to, any airbag when
it inflates can be seriously injured
or killed. Never put a rear-facing
child restraint in the right front
seat. Secure a rear-facing child
restraint in a rear seat. It is also
better to secure a forward-facing
child restraint in a rear seat. If you
must secure a forward-facing
child restraint in the right front
seat, always move the front
passenger seat as far back as it
will go.
Q: What are the different types ofadd-on child restraints?
A: Add-on child restraints, which
are purchased by the vehicle
owner, are available in four basic
types. Selection of a particular restraint should take into
consideration not only the
child's weight, height, and age
but also whether or not the
restraint will be compatible with
the motor vehicle in which it will
be used.
For most basic types of child
restraints, there are many
different models available. When
purchasing a child restraint, be
sure it is designed to be used
in a motor vehicle. If it is, the
restraint will have a label saying
that it meets federal motor
vehicle safety standards.

3-58 Seats and Restraints
The restraint manufacturer's
instructions that come with the
restraint state the weight and
height limitations for a particular
child restraint. In addition, there
are many kinds of restraints
available for children with
special needs.
{WARNING
To reduce the risk of neck and
head injury during a crash, infants
need complete support. This is
because an infant's neck is not
fully developed and its head
weighs so much compared with
the rest of its body. In a crash,
an infant in a rear-facing child
restraint settles into the restraint,
so the crash forces can be
distributed across the strongest
part of an infant's body, the back
and shoulders. Infants should
always be secured in rear-facing
child restraints.
{WARNING
A young child's hip bones are still
so small that the vehicle's regular
safety belt may not remain low
on the hip bones, as it should.
Instead, it may settle up around
the child's abdomen. In a crash,
the belt would apply force on a
body area that is unprotected by
any bony structure. This alone
could cause serious or fatal
injuries. To reduce the risk of
serious or fatal injuries during a
crash, young children should
always be secured in appropriate
child restraints.
Child Restraint Systems
(A) Rear‐Facing Infant Seat
A rear-facing infant seat (A)
provides restraint with the seating
surface against the back of the
infant.
The harness system holds the infant
in place and, in a crash, acts to
keep the infant positioned in the
restraint.

Locking Rear Axle
Vehicles with a locking rear axle can
give more traction on snow, mud,
ice, sand, or gravel. It works like a
standard axle most of the time, but
when traction is low, this feature will
allow the rear wheel with the most
traction to move the vehicle.
Continuous Damping
Control (CDC)
This vehicle may have a continuous
damping control system called
Autoride
®or MagneRide™. With
this feature, improved vehicle ride
and handling is provided under a
variety of passenger and loading
conditions.
Autoride and MagneRide are fully
automatic and use a computer
controller to continuously monitor
vehicle speed, wheel to body
position, lift/dive and steering
position of the vehicle. The
controller then sends signals
to each shock absorber to independently adjust the damping
level to provide the optimum
vehicle ride.
Autoride and MagneRide also
interact with the tow/haul mode
that, when activated, will provide
additional control of the shock
absorbers. This additional control
results in better ride and handling
characteristics when the vehicle is
loaded or towing a trailer. See
“Tow/Haul Mode”
underTrailer
Towing on page 9‑79 for more
information.Automatic Level Control
The automatic level control rear
suspension is available on
light‐duty vehicles and comes as a
part of the Continuous Damping
Control (CDC) suspension,
if equipped. This type of level control is fully
automatic and will provide a better
leveled riding position as well as
better handling under a variety of
passenger and loading conditions.
An air compressor connected to
the rear shocks will raise or lower
the rear of the vehicle to maintain
proper vehicle height. The system
is activated when the ignition key
is turned to ON/RUN and will
automatically adjust vehicle height
thereafter. The system may exhaust
(lower vehicle height) for up to
ten minutes after the ignition key
has been turned off. You may hear
the air compressor operating when
the height is being adjusted.
If a weight‐distributing hitch is
being used, it is recommended to
allow the shocks to inflate, thereby
leveling the vehicle prior to adjusting
the hitch.

9-60 Driving and Operating
.A trailer was attached to the
vehicle, or a bicycle or an object
was hanging out of the liftgate
during the last drive cycle. 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 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.
Side Blind Zone
Alert (SBZA)
The vehicle may have a Side Blind
Zone Alert (SBZA) system. Read
this entire section before using the
system.
{WARNING
SBZA is only a lane changing aid
and does not replace driver
vision. SBZA does not detect:
.Vehicles outside the side
blind zones which may be
rapidly approaching.
.Pedestrians, bicyclists,
or animals.
Failure to use proper care when
changing lanes may result in
damage to the vehicle, injury,
or death. Always check the
outside and rearview mirrors,
glance over your shoulder, and
use the turn signal before
changing lanes.
When the system detects a vehicle
in the side blind zone, amber SBZA
displays light up in the side mirrors.
This indicates that it may be unsafe
to change lanes. Before making a
lane change, always check the
SBZA display, check the outside and rearview mirrors, look over your
shoulder for vehicles and hazards,
and use the turn signal.
SBZA Detection Zones
The SBZA sensor covers a zone of
approximately one lane over from
both sides of the vehicle, 3.5 m
(11 ft). This zone starts at each side
mirror and goes back approximately
5.0 m (16 ft). The height of the
zone is approximately between
0.5 m (1.5 ft) and 2.0 m (6 ft) off the
ground.

10-26 Vehicle Care
Brakes
This vehicle has disc brakes. Disc
brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed.
The sound can come and go or be
heard all the time the vehicle is
moving, except when applying the
brake pedal firmly.
{WARNING
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Notice: Continuing to drive with
worn-out brake pads could result
in costly brake repair. Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear and
evenly tighten wheel nuts in
the proper sequence to torque
specifications in
Capacities and
Specifications on page 12‑2.
Brake linings should always be
replaced as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal
does not return to normal height,
or if there is a rapid increase in
pedal travel. This could be a
sign that brake service might be
required.
Brake Adjustment
Every time the brakes are applied,
with or without the vehicle moving,
the brakes adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is
complex. Its many parts have to be
of top quality and work well together
if the vehicle is to have really good
braking. The vehicle was designed
and tested with top-quality brake
parts. When parts of the braking
system are replaced, be sure to get
new, approved replacement parts.
If this is not done, the brakes might
not work properly. For example,
installing disc brake pads that are
wrong for the vehicle, can change
the balance between the front and
rear brakes —for the worse. The
braking performance expected can
change in many other ways if the
wrong replacement brake parts are
installed.

4. At a wall, measure from theground upward (A) to the
recorded distance from
Step 3 and mark it.
5. Draw or tape a horizontal line (B) on the wall the width of the
vehicle at the height of the mark
in Step 4.
Notice: Do not cover a headlamp
to improve beam cut-off when
aiming. Covering a headlamp may
cause excessive heat build-up
which may cause damage to the
headlamp. 6. Turn on the low-beam
headlamps and place a piece
of cardboard or equivalent in
front of the headlamp not being
adjusted. This allows only the
beam of light from the headlamp
being adjusted to be seen on the
flat surface.
7. Locate the vertical headlamp
aiming screws, which are under
the hood near each headlamp
assembly.
The adjustment screw can be
turned with an E8 Torx
®socket. 8. Turn the vertical aiming screw
until the headlamp beam is
aimed to the horizontal tape
line. Turn it clockwise or
counterclockwise to raise or
lower the angle of the beam.
9. Make sure that the light from theheadlamp is positioned at the
bottom edge of the horizontal
tape line. The lamp on the
left (A) shows the correct
headlamp aim. The lamp on the
right (B) shows the incorrect
headlamp aim.
10. Repeat Steps 7 through 9 for the opposite headlamp.
