Driving and Operating
9-41
While driving on clean dry pavement
and during tight turns, you may
experience vibration in the steering
system.
If the vehicle has StabiliTrak
®
,
shifting into Four-Wheel Drive Low
will turn Traction Control and
StabiliTrak off. See StabiliTrak
Front Axle
The front axle engages and
disengages automatically when you
shift the transfer case. Some delay
for the axle to engage or disengage
is normal.
Manual Transfer Case
The transfer case shift lever is on
the floor to the right of the driver.
Use this lever to shift into and out of
Four-Wheel Drive.
A Four-Wheel Drive indicator light
comes on when you shift into
four-wheel drive and the front axle
engages. See Four-Wheel-Drive
Light on page 5‑26.
Some delay between shifting and
when the indicator light comes on is
normal.
