STARTING AND DRIVING

(g) If you cannot shift the selector lever
If you cannot shift the selector lever even though the brake
pedal is depressed, use the shift lock override button. For
instructions, see If you cannot shift automatic transmission
selector leverº on page 494.
(h) Driving in second start mode
In the second start mode, the transmission system shifts up
from second gear. Use this mode when starting your vehicle
in sand, mud, ice or snow.
To set the second start mode, push the 2nd STRTº switch. In
the second start mode, the 2nd STRTº indicator light comes
on. To cancel the second start mode, push the 2nd STRTº
switch once again.
FOUR-WHEEL DRIVE SYSTEM
(a) Four-wheel drive control
Use the four-wheel drive control lever and center
differential lock button to select the following transfer and
center differential modes.
The Hº and Lº position of the four-wheel drive control lever
provides either lock or unlock mode of the center differential
depending on the center differential lock button position.
Use the center differential lock system if your wheels get stuck
in a ditch, or when you are driving on a slippery or bumpy
surface. When the center differential is locked, the vehicle
stability control system is automatically turned off and the
center dif ferential lock and VSC OFFº indicator lights come on
because the function that controls engine performance
interferes with the process of freeing your wheels.

STARTING AND DRIVING
388The indicator light tells when the differential lock is engaged.
Note that the differential is not still locked as long as the
indicator light remains off.
When
the operation is not completed, the indicator blinks. If the
indicator light does not go off when you push out the center
differential lock switch, drive straight ahead while accelerating
or decelerating, or drive in reverse.
The center differential lock system operation is not completed
within 5 seconds while the cruise control system is set, cancel
the cruise control system. To cancel the cruise control system,
see Cruise controlº on page 394. If the indicator light does not go off when you push out the
center differential lock button, drive straight ahead while
accelerating or decelerating, or drive in reverse.
See (b) Shifting procedureº for further instructions.
Advice for driving on slippery roads in Lº (low speed
position) mode
If you shift the four-wheel drive control lever to Lº, the
automatic transmission lever to 2º when you drive in steep
off-road areas, the output of the brake can be controlled
effectively by the active traction control system, which assists
the driver to control the driving power of 4 wheels.
Use the Lº position of the automatic transmission lever for
maximum power and traction when your wheels get stuck or
when you drive down a steep incline. In the following cases,
the out put of the brake can be controlled by the active traction
control system if the engine speed is under 3,000 rpm
(normally engine speed is under 3,000 rpm when the wheels
get unstuck).

The four-wheel drive control lever in the Lº position and the
automatic transmission lever in the Lº position or the
automatic transmission lever in the Dº or 2º with the
transmission downshifting to the first gear.
 The four-wheel drive control lever in the Lº position and the
automatic transmission lever in the Rº position
(As for the automatic transmission lever positions, see
Automatic transmissionº on page 378.)

STARTING AND DRIVING
389
(b) Shifting procedure
To shift between unlock and lock modes in Hº, push the
center differential lock button.
To shift between unlock and lock modes in Lº, push the
center differential lock button.
To shift between Hº and Lº, stop the vehicle, put the
transmission into Nº and move the four-wheel drive control
lever.CAUTION
Never move the four-wheel drive control lever if wheels
are slipping. Stop the slipping or spinning before
shifting.
NOTICE
For normal driving on dry and hard surface roads, unlock the center differential. To prevent damage to thecenter differential lock system, do not push the centerdifferential lock button when the vehicle is cornering or
when its wheels are spinning freely off the ground. If the
indicator light does not go off when unlocking the center differential, drive straight ahead while
accelerating or decelerating, or drive in reverse.

STARTING AND DRIVING
405
We recommend you to select the mode

2
for ordinary
driving. The damping effect will be changed automatically to
provide good riding comfort.
When your vehicle is loaded heavily or you are driving in an
unpaved road, the mode
3
or 4
will be recommended. To
provide good vehicle stability, the damping effect will be harder
than for ordinary driving mode.
With the four-wheel drive control lever at Lº, the damping
effect suitable for off-road driving will be provided in any mode.
ACTIVE TRACTION CONTROL
SYSTEM
The active traction control system automatically helps
prevent the spinning of 4 wheels when the vehicle is
started or accelerated on slippery road surfaces.
When the ignition key is turned to ONº, the system
automatically turns on.
CAUTION
Under certain slippery road conditions, full traction of
the vehicle and power to the 4 wheels cannot be
maintained, even though the traction control system is
in operation. Do not drive the vehicle under any speed
or maneuvering conditions which may cause the
vehicle to lose traction control. In situations where the
road surface is covered with ice or snow, your vehicle
should be fitted with snow tires or tire chains. Always
drive at an appropriate and cautious speed for the
present road conditions.
