2010 JEEP GRAND CHEROKEE height

Standards. Chrysler Group LLC also recommends that
you try a child restraint in the vehicle seats where you
will use it before you buy it.
•The restraint must be appropriate for your child’s
weight and height. Check the label on the restraint for
weight and height limits.
•Carefully follow the instructions that come with the
restraint. If you install the restraint improperly, it may
not work when you need it.
•Except for the second row center seating position, all
passenger seat belts are equipped with cinching latch
plates. The second row center position has an auto-
matic locking retractor. Both types of seat belts are
designed to keep the lap portion tight around the child
restraint so that it is not necessary to use a locking clip.
If the seat belt has a cinching latch plate, pulling up on
the shoulder portion of the lap/shoulder belt will
tighten the belt (the cinching latch plate will keep thebelt tight; however, any seat belt system will loosen
with time, so check the belt occasionally and pull it
tight if necessary). For the second row center seat belt
with the automatic locking retractor, pull the belt from
the retractor until there is enough allowance to pass it
through the child restraint and slide the latch plate
into the buckle. Then, pull the belt until it is fully
extended from the retractor. Allow the belt to return
into the retractor, pulling on the excess webbing to
tighten the lap portion around the child restraint. For
additional information, refer to
Automatic Locking
Mode.
•In the rear seat, you may have trouble tightening the
lap/shoulder belt on the child restraint because the
buckle or latch plate is too close to the belt path
opening on the restraint. Disconnect the latch plate
from the buckle and twist the short buckle-end belt
several times to shorten it. Insert the latch plate into
the buckle with the release button facing out.

This feature prevents the headlights from interfering
with the vision of oncoming drivers. Headlight leveling
automatically adjusts the height of the headlight beam in
reaction to changes in vehicle pitch.
Instrument Panel Dimmer
Rotate the center potion of the lever to the extreme
bottom position to fully dim the instrument panel lights
and prevent the interior lights from illuminating when a
door is opened.
Rotate the center portion of the lever up to increase the
brightness of the instrument panel lights when the park-
ing lights or headlights are on.
Rotate the center portion of the lever upward to the next
detent position to brighten the odometer and radio when
the parking lights or headlights are on.Rotate the center portion of the lever upward to the last

286 STARTING AND OPERATING

Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or tem-
porary) loaded in or on the trailer in itsloaded and
ready for operation condition. The recommended way to
measure GTW is to put your fully loaded trailer on a
vehicle scale. The entire weight of the trailer must be
supported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of your vehicle
and trailer when weighed in combination.
NOTE: The GCWR rating includes a 150 lbs (68 kg)
allowance for the presence of a driver.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR.
WARNING!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have an accident.
Trailer Tongue Weight (TW)
The TW is the downward force exerted on the hitch ball
by the trailer. In most cases it should not be less than 10%
or more than 15% of the trailer load. You must consider
this as part of the load on your vehicle.
Frontal Area
The frontal area is the maximum height and maximum
width of the front of a trailer.
