ROOF LUGGAGE RACK
External racks do not increase the total load carrying
capacity of the vehicle. Be sure that the total occupant
and luggage load inside the vehicle, plus the load on the
luggage rack, do not exceed the rated vehicle capacity as
shown on the label attached to the drivers door shut face.CAUTION!
•To avoid damage to the roof rack and vehicle, do not
exceed the maximum roof rack load capacity of 150
lbs (68 kg). Always distribute heavy loads as evenly
as possible and secure the load appropriately.
•Long loads which extend over the windshield,
such as wood panels or surfboards, should be
secured to both the front and rear of the vehicle.
•Place a blanket or other protection between the
surface of the roof and the load.
•Travel at reduced speeds and turn corners carefully
when carrying large or heavy loads on the roof rack.
Wind forces, due to natural causes or nearby truck
traffic, can add sudden upward loads. This is espe-
cially true on large flat loads and may result in
damage to the cargo or your vehicle.

WARNING!
Driving a vehicle with the BRAKE warning light on
is dangerous. A significant decrease in braking per-
formance or vehicle stability during braking may
occur. It will take you longer to stop the vehicle or
will make your vehicle harder to control. You could
have an accident. Have the vehicle checked immedi-
ately.
The operation of the BRAKE warning light can be
checked by turning the ignition switch from the OFF
position to the ON position. The light should illuminate
for approximately two seconds. The light should then
turn off unless the parking brake is applied or a brake
fault is detected. If the light does not illuminate, have the
light inspected by an authorized dealer.Also, the light will come on when the parking brake is
applied with the ignition switch in the ON position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
If the parking brake is off and the light remains on, have
the brake system inspected as soon as possible.
19. Full Time Indicator Light — If Equipped
This light alerts the driver that the vehicle is in
the FULL TIME four–wheel drive mode, and
employs the inter-axle differential which al-
lows the front and rear wheels to rotate at
different speeds.
20. Sentry Key/Security Alarm Indicator Light — If
Equipped
Refer to “Sentry Key Immobilizer System” or “Vehicle
Security Alarm” in Section 2 of this manual for more
information.

including dry hard surfaced roads. The 4 FULL TIME
mode allows the front and rear wheels to rotate at
different speeds which eliminates driveline binding and
component wear that is normally associated with driving
the vehicle in the 4 PART TIME position on dry hard
surfaced roads. This feature provides the safety, security,
and convenience of operating in 4–wheel drive at all
times regardless of road conditions.
When additional traction is required the 4 PART TIME
and 4LO positions can be used to lock the front and rear
driveshafts together through the transfer case inter-axle
differential and force the front and rear driveshafts to
rotate at the same speed. This is accomplished by simply
moving the shift lever to these positions. The 4 PART
TIME and 4LO positions are intended for loose, slippery
road surfaces only. Driving in the 4 PART TIME and 4LO
positions on dry hard surfaced roads may cause in-
creased tire wear and damage to driveline components.The PART TIME indicator light, located on the instru-
ment cluster, illuminates when the transfer case is shifted
to the 4 PART TIME position.
The FULL TIME indicator light, located on the instru-
ment cluster, illuminates when the transfer case is shifted
to the 4 FULL TIME position.
The 4LO MODE indicator light, located on the instru-
ment cluster, illuminates when the transfer case is shifted
to the 4LO position. There is no light for the 2WD, or N
(Neutral) positions.
230 STARTING AND OPERATING

within the specified GVWR. If so, weight must be shifted
from front to rear or rear to front as appropriate until the
specified weight limitations are met. Store the heavier
items down low and be sure that the weight is distributed
equally. Stow all loose items securely before driving.
Improper weight distributions can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
CAUTION!
Do not load your vehicle any heavier than the
GVWR or the maximum front and rear GAWR. If
you do, parts on your vehicle can break, or it can
change the way your vehicle handles. This could
cause you to lose control. Also overloading can
shorten the life of your vehicle.
TRAILER TOWING
In this section you will find safety tips and information
on limits to the type of towing you can reasonably do
with your vehicle. Before towing a trailer carefully re-
view this information to tow your load as efficiently and
safely as possible.
To maintain warranty coverage, follow the requirements
and recommendations in this manual concerning ve-
hicles used for trailer towing.
Common Towing Definitions
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR.
282 STARTING AND OPERATING

WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
•When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
•Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
P for Park. With a manual transmission, shift the
transmission into reverse. And with four-wheel-drive
vehicles, make sure the transfer case is not in neutral.
Always, block orchockthe trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
