Four-Wheel Drive

If equipped with four-wheel drive, the
engine's driving power can be sent to all
four wheels for extra traction.
Caution
Do not drive on clean, dry pavement in
4 and 4 (if equipped) for an extended
period of time. These conditions may
cause premature wear on the vehicle s
powertrain.
Driving on clean, dry pavement in 4 or
4 may:
Cause a vibration to be felt in the
steering system.
Cause tires to wear faster.
Make the transfer case harder to shift,
and cause it to run noisier.
Warning
If equipped with four-wheel drive, the
vehicle will be free to roll if the transfer
case is in N (Neutral), even when the shift

lever is in P (Park). You or someone else
could be seriously injured. Be sure the
transfer case is in a drive gear
or 4 or set the parking brake before
placing the transfer case in N (Neutral).
See Shifting Into Park 0 203.
Extended high-speed operation in 4
may damage or shorten the life of the
drivetrain.

between 4 and 4 , with the engine
running, is normal.
Manual Locking Hubs
