There are different sizes and types of restraints for children
from newborn size to the child almost large enough for an
adult safety belt. Always check the child seat Owner ’s
Manual to make sure you have the correct seat for your
child. Carefully read and follow all the instructions and
warnings in the child restraint Owner ’s Manual and on all
the labels attached to the child restraint.
Before buying any restraint system, make sure that it has a
label certifying that it meets all applicable Safety Stan-
dards. You should also make sure that you can install it in
the vehicle where you will use it.NOTE:

Infants and Toddlers Children who are two years old or
younger and who have not reached the height or weight limits of their child restraint Either an Infant Carrier or a Convert-
ible Child Restraint, facing rearward in the rear seat of the vehicle
Small Children Children who are at least two years
old or who have outgrown the
height or weight limit of their rear- facing child restraint Forward-Facing Child Restraint with
a five-point Harness, facing forward in the rear seat of the vehicle

SAFETY 253

Child Size, Height, Weight Or AgeRecommended Type Of Child
Restraint
Larger Children Children who have outgrown their
forward-facing child restraint, but are too small to properly fit the vehicle’s seat belt Belt Positioning Booster Seat and the
vehicle seat belt, seated in the rear seat of the vehicle
Children Too Large for Child Restraints Children 12 years old or younger,
who have outgrown the height or weight limit of their booster seat Vehicle Seat Belt, seated in the rear
seat of the vehicle
Infant And Child Restraints
Safety experts recommend that children ride rear-facing in
the vehicle until they are two years old or until they reach
either the height or weight limit of their rear-facing child
restraint. Two types of child restraints can be used rear-
facing: infant carriers and convertible child seats.
The infant carrier is only used rear-facing in the vehicle. It
is recommended for children from birth until they reach
the weight or height limit of the infant carrier. Convertible
child seats can be used either rear-facing or forward-facing
in the vehicle. Convertible child seats often have a higher
weight limit in the rear-facing direction than infant carriers
do, so they can be used rear-facing by children who have
outgrown their infant carrier but are still less than at least two years old. Children should remain rear-facing until
they reach the highest weight or height allowed by their
convertible child seat.
WARNING!
•
Never place a rear-facing child restraint in front of an
air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.
• Only use a rear-facing child restraint in a vehicle
with a rear seat.
254 SAFETY

WARNING!
Do not install a rear-facing car seat using a rear support
leg in this vehicle. The floor of this vehicle is not
designed to manage the crash forces of this type of car
seat. In a crash, the support leg may not function as it
was designed by the car seat manufacturer, and your
child may be more severely injured as a result.
Older Children And Child Restraints
Children who are two years old or who have outgrown
their rear-facing convertible child seat can ride forward-
facing in the vehicle. Forward-facing child seats and con-
vertible child seats used in the forward-facing direction are
for children who are over two years old or who have
outgrown the rear-facing weight or height limit of their
rear-facing convertible child seat. Children should remain
in a forward-facing child seat with a harness for as long as
possible, up to the highest weight or height allowed by the
child seat.
All children whose weight or height is above the forward-
facing limit for the child seat should use a belt-positioning
booster seat until the vehicle’s seat belts fit properly. If the
child cannot sit with knees bent over the vehicle’s seat
cushion while the child’s back is against the seatback, they
should use a belt-positioning booster seat. The child and
belt-positioning booster seat are held in the vehicle by the
seat belt.

If the vehicle is in OFFROAD1 or OFFROAD2 setting,
be aware of your surroundings, you may not have the
clearance required for certain areas and vehicle dam-
age may occur.
• Aero Mode (Lowers the vehicle approximately .6 in [15
mm]) – This position provides improved aerodynamics
by lowering the vehicle. The vehicle will automatically
enter Aero Mode when the vehicle speed remains be-
tween 62 mph (100 km/h) and 66 mph (106 km/h) for
greater than 20 seconds or if the vehicle speed exceeds 66 mph (106 km/h). The vehicle will return to NRH from
Aero Mode if the vehicle speed remains between 30 mph
(48 km/h) and 35 mph (56 km/h) for greater than 20
seconds or if the vehicle speed falls below 30 mph
(48 km/h).

Protection Strategy
In order to “protect” the air suspension system, the vehicle
will disable load leveling as required (suspension over-
loaded, battery charge low, etc.). Load leveling will auto-
matically resume as soon as system operation requirements
are met. See your authorized dealer if system does not
resume.
NOTE:If towing with air suspension refer to “Trailer
Towing” in “Starting And Operating” for further informa-
tion.
Instrument Cluster Display Messages
When the appropriate conditions exist, a message will
appear in the instrument cluster display. Refer to “Instru-
ment Cluster Display” in “Getting To Know Your Instru-
ment Panel” for further information.
An audible chime will be heard whenever a system error
has been detected.
