198 Driving and Operating
If the Automatic Mode is selected when the
vehicle is in the process of turning, the
mode will not engage until the turn is
complete.
CrabWalk Mode : Allows the driver to turn
the rear wheels at the same angle as the
front wheels enabling the vehicle to move
diagonally.
Off Mode : Disengages the four-wheel
steering feature. The vehicle will be steered
with the front wheels and the rear wheels
will be in the forward position.
At slower speeds the front and rear wheels
will turn in opposite directions (except in
the CrabWalk Mode). This helps the vehicle
make tighter turns, such as during parking,
cornering and turning into tight spaces. At
higher speeds the front and rear wheels will
turn in the same direction. This improves
stability of the vehicle during lane changes
and wide turns
When the vehicle is shut-off, the rear
steering angle will automatically return to
the forward position.
When the vehicle is stationary, the full
10 degrees of rear steering angle may not
be available until the vehicle begins
to move.
Maximum vehicle speed may be limited if
the four-wheel steering system becomes
inoperable.
When towing a trailer the four-wheel
steering provides enhanced stability allowing
the trailer to follow the path of the tow
vehicle more closely, especially during lane
changes. See General Towing Information
0 252 for more information on towing a
trailer.

Driver Mode Control rotary switch on the
