Power is supplied to all four wheels
through a transfer case or power
transfer unit. 4WD vehicles allow
you to select different drive modes
as necessary. Information on shifting
procedures and maintenance can be
found in yourOwner’s Guide.You
should become thoroughly familiar
with this information before you operate your vehicle.
On some 4WD models, the initial shift from two-wheel drive to 4WD
while the vehicle is moving can cause a momentary clunk and ratcheting
sound. These sounds are normal as the front drivetrain comes up to
speed and is not cause for concern.
Do not become overconfident in the ability of 4WD and AWD
vehicles. Although a 4WD or AWD vehicle may accelerate better
than 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.
How your vehicle differs from other vehicles
SUV 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.
