2. Route the tether strap to provide the most direct pathbetween the anchorage and the child seat. The tether
strap should go between the head restraint posts under-
neath the head restraint. You may need to adjust the
head restraint to the upward position to pass the tether
strap underneath the head restraint and between its
posts. 3. Lift the cover (if so equipped), and attach the hook to the
square opening in the sheet metal. Tighten the tether
strap according to the child seat manufacturer ’s instruc-
tions.
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.

SAFETY 273

Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can even-
tually poison you. To avoid breathing (CO), follow
these safety tips:
•Do not run the engine in a closed garage or in
confined areas any longer than needed to move your
vehicle in or out of the area.
• If you are required to drive with the trunk/liftgate/
rear doors open, make sure that all windows are
closed and the climate control BLOWER switch is set
at high speed. DO NOT use the recirculation mode.
• If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling con-
trols to force outside air into the vehicle. Set the
blower at high speed.
The best protection against carbon monoxide entry into the
vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the complete
exhaust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams or
loose connections could permit exhaust fumes to seep into
the passenger compartment. In addition, inspect the ex-
haust system each time the vehicle is raised for lubrication
or oil change. Replace as required.
Safety Checks You Should Make Inside The Vehicle
Seat Belts
Inspect the seat belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a collision.
Rear seat belt assemblies must be replaced after a collision
if they have been damaged (i.e., bent retractor, torn web-
bing, etc.). If there is any question regarding seat belt or
retractor condition, replace the seat belt.
Air Bag Warning Light
The Air Bag warning lightwill turn on for four to
eight seconds as a bulb check when the ignition switch
is first turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while driving, 5

The National Forest Service, Bureau of Land Management,
or local Department of Natural Resources are a wealth of
information and usually have maps with marked trails.
Skid Plates And Underbody Protection
Steel skid plates protect the major driveline components of
the truck including the fuel tank, transfer case and steering
damper. In addition, this vehicle is equipped with boxed
cross members and fore/aft rails. This additional protec-
tion allows the vehicle to be utilized in severe off-road
situations that would be considered impassable by a nor-
mal truck.
Ramp Travel Index (RTI)
The ramp travel index is the distance, in inches, that you
can drive your vehicle with one wheel on a 20-degree ramp
without lifting any other wheel off the ground. This
distance up the ramp divided by the wheelbase of the
vehicle and multiplied by 1,000 is the RTI. This vehicle has
an RTI of 510, which means you can articulate one front
wheel 26 inches (66 cm) in the air while the other three
wheels remain in contact with the ground.
Water Fording Characteristics
Water fording characteristic is the vehicle’s ability to cross
a body of still water, where the powertrain and drivetrainare safe from water ingestion. This vehicle has high water
fording characteristics with the ability to cross a pool of
water, without stopping, 24 inches (60 cm) deep at a
maximum speed of 10 mph (16 km/h) and a pool of water
30 inches (76 cm) deep at a maximum speed of 5 mph
(8 km/h), both with an entrance ramp angle of 1.3 degrees.
CAUTION!
The door sill height is 25 inches (63.5 cm). Water may
intrude into the interior of the vehicle at greater
depths.
Simultaneous Brake And Throttle Operation
Many off-road driving conditions require the simultaneous
use of the brake and throttle (two footed driving). When
climbing rocks, logs, or other stepped objects, using light
brake pressure with light throttle will keep the vehicle from
jerking or lurching. This technique is also used when you
need to stop and restart a vehicle on a steep incline.
The Basics Of Off-Road Driving
You will encounter many types of terrain driving off-road.
You should be familiar with the terrain and area before
proceeding. There are many types of surface conditions:
hard packed dirt, gravel, rocks, grass, sand, mud, snow

STARTING AND OPERATING 363

Crossing Obstacles (Rocks And Other High Points)
While driving off road, you will encounter many types of
terrain. These varying types of terrain bring different types
of obstacles. Before proceeding review the path ahead to
determine the correct approach and your ability to safely
recover the vehicle if something goes wrong. Keeping a
firm grip on the steering wheel, bring the vehicle to a
complete stop and then inch the vehicle forward until it
makes contact with the object. Apply the throttle lightly
while holding a light brake pressure and ease the vehicle
up and over the object.
WARNING!
Crossing obstacles can cause abrupt steering system
loading which could cause you to loose control of your
vehicle.
Using A Spotter
There are many times where it is hard to see the obstacle or
determine the correct path. Determining the correct path
can be extremely difficult when you are confronting many
obstacles. In these cases have someone guide you over,
through, or around the obstacle. Have the person stand asafe distance in front of you where they can see the
obstacle, watch your tires and undercarriage, and guide
you through.
Crossing Large Rocks
When approaching large rocks, choose a path which en-
sures you drive over the largest with your tires. This will
lift your undercarriage over the obstacle. The tread of the
tire is tougher and thicker than the side wall and is
designed to take the abuse. Always look ahead and make
every effort to cross the large rocks with your tires.
CAUTION!
•
Never attempt to straddle a rock that is large enough
to strike your axles or undercarriage.
• Never attempt to drive over a rock which is large
enough to contact the door sills.
Crossing A Ravine, Gully, Ditch, Washout Or Rut
When crossing a ravine, gully, ditch, washout or a large rut,
the angled approach is the key to maintaining your vehi-
cle’s mobility. Approach these obstacles at a 45-degree
angle and let each tire go through the obstacle indepen-
dently. You need to use caution when crossing large
obstacles with steep sides. Do not attempt to cross any

CAUTION!
•When installing the power distribution center cover,
it is important to ensure the cover is properly posi-
tioned and fully latched. Failure to do so may allow
water to get into the power distribution center and
possibly result in an electrical system failure.
• When replacing a blown fuse, it is important to use
only a fuse having the correct amperage rating. The
use of a fuse with a rating other than indicated may
result in a dangerous electrical system overload. If a
properly rated fuse continues to blow, it indicates a
problem in the circuit that must be corrected.
