Study your owner's manual and any
supplements for specific information about
equipment features, instructions for safe
driving and additional precautions to
reduce the risk of an accident or serious
injury.
Four-wheel drive system (If Equipped)
WARNING:
Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel
drive vehicle may accelerate better than
a two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive
at a safe speed.
A vehicle equipped with four-wheel drive,
when selected, has the ability to use all
four wheels to power itself. This increases
traction which may enable you to safely
drive over terrain and road conditions that
a conventional two-wheel drive vehicle
cannot.
Power is supplied to all four wheels
through a transfer case or power transfer
unit. Four-wheel drive vehicles allow you
to select different modes as necessary. For
information on transfer case operation and
shifting procedures, See
Four-Wheel
Drive (page 213). For information on
transfer case maintenance, See
Maintenance (page 348). You should
become thoroughly familiar with this
information before you operate your
vehicle.
On some four-wheel drive vehicles, the
initial shift from two-wheel to four-wheel
drive when the vehicle is moving can cause
a momentary clunk and ratcheting sound.
These sounds are normal and are not
cause for concern. In four-wheel drive vehicles, the size of the
spare tire relative to the remaining tires can
have an effect on the 4x4 system. If there
is a significant difference between the size
of a spare and the remaining tires,
four-wheel drive functionality may be
limited.
See Using Four-Wheel Drive
(page 213).
How your vehicle differs from
other vehicles
Sport utility vehicles and trucks can differ
from some other vehicles in a few
noticeable ways. Your vehicle may be:
• Higher - to allow higher load carrying
capacity and to allow it to travel over
rough terrain without getting hung up
or damaging underbody components.
• Shorter - to give it the capability to
approach inclines and drive over the
crest of a hill without getting hung up
or damaging underbody components.
All other things held equal, a shorter
wheelbase may make your vehicle
quicker to respond to steering inputs
than a vehicle with a longer wheelbase.
• Narrower - to provide greater
maneuverability in tight spaces,
particularly in off-road use.
As a result of the above dimensional
differences, Sport utility vehicles and
trucks often have a higher center of gravity
and a greater difference in center of gravity
between the loaded and unloaded
condition. These differences that make
your vehicle so versatile also make it
handle differently than an ordinary
passenger car.

to install the spare tire.
Note:
Hydraulic jacks have a pressure relief
valve that prevents lifting loads which
exceed the jack's rated capacity.
