2008 JEEP GRAND CHEROKEE height

Here are some tips for getting the most out of your child
restraint:
²Before buying any restraint system, make sure that it
has a label certifying that it meets all applicable Safety
Standards. The manufacturer also recommends that
you try a child restraint in the vehicle seats where you
will use it before you buy it.
²The restraint must be appropriate for your child's
weight and height. Check the label on the restraint for
weight and height limits.
²Carefully follow the instructions that come with the
restraint. If you install the restraint improperly, it may
not work when you need it.
²Except 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 aredesigned 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 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 to9Automatic Locking Mode9ear-
lier in this section.
²In the rear seat, you may have trouble tightening the
lap/shoulder belt on the child restraint because the

even when the doors and liftgate are open. While in the
ªOffº position the instrument panel lighting is at the
lowest light level and may not be suitable for night
driving.
Daytime Running Lights Ð If Equipped
The high beam headlights come on at a low intensity
level whenever the engine is running, and the transmis-
sion in not in the P (Park) position. The lights will remain
on until the ignition switch is turned to LOCK/ACC, or
the parking brake is engaged. The headlight switch must
be used for normal night time driving.
Automatic Headlight Leveling Ð HID Headlights
Only
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.
Lights-On Reminder
If the headlights or parking lights are on after the ignition
switch has been turned to LOCK/ACC, a chime will
sound when the driver's door is opened.
Fog Lights Ð If Equipped
The fog light switch is located in the multi-
function control lever. To activate the fog lights,
turn on the park/turn lights, low beam headlights,
or ªAutoº headlights and pull out the end of the multi-
function control lever. A light in the instrument cluster
shows when the fog lights are on.
NOTE:Turning on the high beam headlights turns off
the fog lights.
A front fog light is a lighting device providing illumina-
tion forward of the vehicle under conditions of fog, rain,
snow, or dust. Principally, the front fog light supplements
the lower beam of a standard headlight system.

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:The radio, steering wheel radio controls (if
equipped), and 6 disc CD/DVD changer (if equipped)
will remain active for up to 10 minutes after the ignition
switch has been turned off. Opening a vehicle front door
will cancel this feature.

Gross Combination Weight Rating (GCWR)
The gross combination weight rating (GCWR) is the total
permissible weight of your vehicle and trailer when
weighed in combination. (Note that GCWR ratings in-
clude 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.
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 tongue
that typically provides adjustable friction associated with
the telescoping motion to dampen any unwanted trailer
swaying motions while traveling.
