When driving
■When the rear differential is locked (vehicles with the rear differential
lock system)
The active traction control system is activated only when the vehicle speed
is less than 4 mph (6 km/h).
■ Sounds and vibrations caused by the active traction control system
●A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate that a malfunction has occurred in the system.
● Vibrations may be felt through the vehicle body and steering. It may
occur when the system is operating.
■ If the brake system overheats
The system will cease operation and a buzzer will sound to alert the driver.
Stop the vehicle in a safe place. (Ther e is no problem with continuing normal
driving.)
CAUTION
■ The active traction control system m ay not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the active traction control system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.

2-4. Using other driving systems
AUTO LSD system (2WD models)
When the AUTO LSD system is operatingIf the rear wheels spin, the slip
indicator flashes to indicate that
the AUTO LSD system has con-
trolled the spinning of the rear
wheels.
The AUTO LSD system aids traction by using the traction control
system to control engine performance and braking when one of the
rear wheels begins to spin.
The system should be used only wh en wheel spinning occurs in a
ditch or rough surface.
■ System operation
The system is activated when driving at a speed under 62 mph
(100 km/h).
Press the VSC OFF switch to
turn on the system.
At this time, the AUTO LSD
and VSC OFF indicators will
come on.
To turn off the system, push
the switch again.

When driving
■If the engine is turned off and restarted
The AUTO LSD system and the indicators are automatically turned off.
■ Reactivation of the VSC system linked to vehicle speed
When the AUTO LSD system is turned on, the VSC system will turn on auto-
matically if vehicle speed increases.
■ If the brake system overheats
The system will cease operation and a buzzer will sound to alert the driver.
Stop the vehicle in a safe place. (Ther e is no problem with continuing normal
driving.)
The system will be automatically restored after a short time.
CAUTION
■ To avoid an accident
●Do not use the AUTO LSD system in conditions other than the above.
A much greater steering effort and more careful cornering control will be
required.
● Do not drive with the AUTO LSD system continuously turned on.

Rear differential lock system
Using the rear differential lock systemAutomatic transmission 4WD models: Before using the rear differential lock system.
Stop the vehicle, shift the shift lever to N and shift the front-
wheel drive control lever into L4 to see if this is sufficient. If
this has no effect, additionally use the rear differential lock
system.
Be sure to stop the wheels.
Press the RR DIFF LOCK switch.
Gently depress the accelerator pedal.
After the rear differential is locked, the indicator will come on.
Unlock the rear differential as soon as the vehicle moves.
To unlock the rear differential, push the switch again.
: If equipped
The rear differential lock system is provided for use only when wheel
spinning occurs in a ditch or on a slippery or rugged surface.
The rear differential lock system is effective in case one of the rear
wheels is spinning.
Press the RR DIFF LOCK
switch to lock the rear differen-
tial.
At this time, the rear differential
lock indicator will blink. Wait a
few seconds for the system to
complete operation. After the
rear differential is locked, the
indicator will stop blinking and
remain on.
To unlock the rear differential,
push the switch again.

When driving
Manual transmission
Before using the rear differential lock system.
Stop the vehicle or reduce your speed to less than 5 mph (8
km/h). Depress the clutch pedal and shift the four-wheel drive
control lever into LL to see if this is sufficient. If this has no
effect, additionally use the r ear differential lock system.
Be sure to stop the wheels.
Depress the clutch pedal.
Press the RR DIFF LOCK switch.
Slowly release the clutch pedal.
After the rear differential is locked, the indicator will come on.
Unlock the rear differential as soon as the vehicle moves.
To unlock the rear differential, push the switch again.
■ Locking the rear differential
●When the rear differential is locked, VSC is automatically turned off.
(The rear differential lock and VSC OFF indicators will come on.)
● The following systems do not operate when the rear differential is locked.
It is normal operation for the ABS warning light and VSC OFF indicator to
be on at this time.
•ABS
• Brake assist system
•VSC
• TRAC (TRC)
■ The rear differential lock is disengaged when
●Shift the four-wheel drive control lever to H or HL. (4WD models with a
manual transmission)
● Shift the front-wheel drive control lever to H2 or H4. (4WD models with
an automatic transmission)
Never forget to turn off the switch after using this feature.
■ After unlocking the rear differential
Check that the indicator goes off.

176 2-4. Using other driving systems
CAUTION
■To avoid an accident
●Do not use the rear differential lock system except when wheel spinning
occurs in a ditch or on a slippery or ragged surface. Large steering effort
and careful cornering control will be required.
● Do not lock the rear differential until the wheels have stopped spinning.
Otherwise, the vehicle may move in an unexpected direction when the dif-
ferential lock is engaged, resulting in an accident. This may also lead to
possible damage to rear differential lock component parts.
● Do not drive over 5 mph (8 km/h) when the rear differential is locked.
● Do not keep driving with the RR DIFF LOCK switch on.

Clutch star t cancel switch (vehicles with a manual transmission)
■Clutch start system
The system is designed to keep the starter motor from operating if the clutch
pedal is not depressed all the way down.
The switch allows the vehicle to be driven out of difficult situations
by cranking the engine with the clutch engaged.
Never use the switch for normal engine starting. Be sure to follow the
starting procedure. ( P. 127)
Press the CLUTCH START
CANCEL switch to cancel the
clutch start system with the
engine switch is turned to the
ON position.
The indicator will come on
when the clutch start system is
canceled.
The clutch start cancel switch
is automatically turned off
when the engine switch is
turned off.

2-4. Using other driving systems
Driving assist systems
When TRAC (TRC)/VSC are operatingIf the vehicle is in danger of slip-
ping, or if the rear wheels (2WD
models) or any of the drive
wheels (4WD models) spins, the
slip indicator flashes to indicate
that TRAC (TRC)/VSC have
been engaged.
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too h eavily when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface.
■Brake Assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
■TRAC/TRC (Traction Control)
Maintains drive power and prevents the rear wheels (2WD models) or
all wheels (4WD models) from spinning when starting the vehicle or
accelerating on slippery roads.
