USING THE 2WD/4WD
SWITCH
(for versions/markets, where provided)
This 4WD system enables you to select the
driving mode according to the driving con-
ditions by operating the 2WD/4WD
switch. With this feature, you can select 3
mode positions, “2WD”, “4WD AUTO”
and “4WD LOCK” by operating the 2WD/
4WD switch even when the vehicle is mov-
ing, provided the front wheels are in the
straight ahead position.
DESCRIPTION OF 3 MODE 4 X 4
SYSTEM POSITIONS
2WD
In this position, engine power is supplied
to the front axle only. Use this position
for normal driving (on dry, hard surfaces).
4WD AUTO
In this position, engine power is supplied
to the front and rear axles at normal
speed, providing greater traction than 2-
wheel drive. Use this position for driving
on paved roads or on slippery roads (icy,
snow-covered, muddy, etc.).
In the AUTO mode, the 4WD controller
judges the driving conditions using signals
from sensors.
When slipping of the front wheels is de-
tected, the electronically controlled cou-
pling supplies optimum driving force to the
rear wheels. This function improves dri-
ving stability and running through perfor-
mance on rough roads and stabilizes dri-
ving performance even on a snow covered
up- hill road or the like.
Also, during normal driving on paved
roads, torque distribution to the rear
wheels is reduced to achieve the nearly
front wheel drive condition, thereby fuel
consumption is improved.

4WD LOCK
In this position, engine power is supplied
to the front and rear axles at reduced
speed. Use this position when it is hard to
start off in the “4WD AUTO” mode such
as in mud, sand or on snow.
NOTE
❒ Avoid operating your vehicle in the
“4WD LOCK” on wet pavement as
much as possible. Operating your vehi-
cle in the “4WD LOCK” on wet pave-
ment may cause severe damage to the
drive train.
❒ As the vehicle speed increases, the
“4WD LOCK” mode is automatically
canceled and the “4WD AUTO” mode
is selected.
❒ When the ignition switch is turned to
the “OFF” position, the “4WD LOCK”
mode is canceled.
