selector lever to the Dº position after climbing the slope.

STARTING AND DRIVING
372When towing a trailer, in order to maintain efficient engine
braking and electrical charging performance, do not use
overdrive.
CAUTION
Always keep your foot on the brake pedal while stopped
with the engine running. This prevents the vehicle from
creeping.
NOTICE
Always use the brake pedal or parking brake to hold the
vehicle on an upgrade. Do not attempt to hold the
vehicle using the accelerator pedal, as this can cause
the transmission to overheat.

(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 466.
(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 differential 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
374
NOTICE
As soon as the center differential lock switch is turned
on, the VSC OFFº indicator light comes on. After the
wheels are out of the ditch or off the slippery or bumpy
surface, turn the center differential lock switch off.
Make sure the center differential lock indicator light and
vehicle stability control system off indicator light turn
off.
Hº (high speed position, center differential unlocked):
Lever at Hº, center differential lock button left out
Use this for normal driving on all types of roads, from dry
hard-surfaced roads to wet, icy or snow-covered roads. This
position gives greater economy, quietest ride, least wear and
better vehicle control.
Hº (high speed position, center differential locked): Lever
at Hº, center differential lock button pushed in
Use this for greater traction when you experience a loss of
power, such as wheel slipping, in the center differential unlock
mode.
Nº (neutral position): Lever at Nº
No power is delivered to the wheels. The vehicle must be
stopped.Lº (low speed position, center differential unlocked):
Lever at Lº, center differential lock button left out
Use this for maximum power and traction. Use this for climbing
or descending steep hills, off-road driving, and hard pulling in
sand or mud.
In this mode, the braking feeling that occurs when the wheels
are negotiating a sharp corner is further reduced than in the Lº
(low position, center differential locked) mode.
Lº (low speed position, center differential locked): Lever
at Lº, center differential lock button pushed in
Use this for maximum power and traction. Use this for hard
pulling in situations the vehicle cannot negotiate even in the Lº
(low speed position, center differential unlocked) mode. Also,
using this mode when driving down steep off-road inclines will
help contribute to increased vehicle stability.

STARTING AND DRIVING
375 The 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 377.
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 365.)

(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 the
center differential lock system, do not push the center
differential 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.

CRUISE CONTROL
The cruise control allows you to cruise the vehicle at a
desired speed over about 40 km/h (25 mph) with your foot
off the accelerator pedal.
Your cruising speed can be maintained although a slight speed
change may occur when driving up or down a gradient, within
the limits of engine performance. On steeper hills, a greater
speed change will occur so it is better to drive without the cruise
control.
When the cruise control is on, the driving pattern of the
automatic transmission is fixed in the normal position,
regardless of the position of the driving pattern selector switch.
CAUTION
To help maintain maximum control of your vehicle,
do not use the cruise control when driving in heavy
or varying traffic, or on slippery (rainy, icy or
snow-covered) or winding roads.
Avoid vehicle speed increases when driving
downhill. If the vehicle speed is too fast in relation to
the cruise control set speed, cancel the cruise
control then downshift the transmission to use
engine braking to slow down.
Turning the system on
To operate the cruise control, push the main switch. This turns
the system on. The indicator light in the instrument cluster
shows that you can now set your desired cruising speed.
Another push on the switch will turn the system completely off.
When the ignition key is turned off, the main switch is also
automatically turned off. To use the cruise control again, push
the main switch again to turn it on.
CAUTION
To avoid accidental cruise control engagement, keep
the main switch off when not using the cruise control.
