2006 JEEP GRAND CHEROKEE height

Standards. The manufacturer 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 identified by a distinctive label.
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 por-
tion of the lap/shoulder belt will tighten the belt (thecinching latch plate will keep the belt 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 to allow you to pass through the child restraint
and slide the latch plate into the buckle. Then, pull the
belt until it is fully extracted from the retractor. Allow
the belt to return to the retractor, pulling on the excess
webbing to tighten the lap portion about the child
restraint. For additional information, refer toAuto-
matic Locking Modeearlier in this section.
•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.
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Two Types of Signals
There are two basic types of radio signals... AM or
Amplitude Modulation, in which the transmitted sound
causes the amplitude, or height, of the radio waves to
vary... and FM or Frequency Modulation, in which the
frequency of the wave is varied to carry the sound.
Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.
NOTE:On vehicles so equipped the radio, steering
wheel radio controls and 6 disc CD/DVD changer will
remain active for up to 45 seconds after the ignition
switch has been turned off. Opening a vehicle front door
will cancel this feature.

280 STARTING AND OPERATING

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.
Tongue Weight (TW)
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 maximum height and maximum width of the front of
a trailer.
Trailer Sway Control
The trailer sway control is a telescoping link that can be
installed between the hitch receiver and the trailer tonguethat typically provides adjustable friction associated with
the telescoping motion to dampen any unwanted trailer
swaying motions while traveling.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch ball or
some other connecting point of the vehicle. These kind of
hitches are the most popular on the market today and
they’re commonly used to tow small- and medium-sized
trailers.
Weight-Distributing Hitch
A weight-distributing hitch includes a receiver attached
to the tow vehicle, plus a removable hitch head and
spring bar assembly that fits into the receiver opening
and hook up brackets that connect the spring bars to the
trailer frame.
