Driving
●Shifting to “4H” or “4L”
Automatic transmission
If the “4LO” indicator continues to blink when you operate the front-wheel
drive control switch to the “4H” or “4L” position, drive forwar d or backward
in a short distance, then stop the vehicle completely, shift th e shift lever
securely to N and operate the switch again.
Manual transmission
If the “4LO” indicator continues to blink when you operate the front-wheel
drive control switch to the “4H” or “4L” position, drive forwar d or backward
in a short distance, then stop the vehicle completely, depress the clutch
pedal and operate the switch again.
If the indicator light continues to blink even if doing so, contact your Toyota
dealer as soon as possible. There may be a trouble in the four- wheel drive
system.
■ Shifting to “4L”
VSC is automatically turned off.
■ Four-wheel drive usage frequency
You should drive in four-wheel drive for at least 10 miles (16 km) each month.
This will assure that the front drive components are lubricated.
WARNING
■Caution while driving
● Never shift the front-wheel drive control switch from “2WD” to “4H” if the
wheels are slipping.
Stop the slipping or spinning before shifting.
● For normal driving on dry and hard surface roads, use “2WD” pos ition.
Driving on dry and hard surface roads in “4H” or “4L” position may cause
drive component oil leakage, seizure, or other problems resulti ng in an
accident. Further, it may cause tire wear and increased fuel consumption.
● Avoid turning suddenly in “4H” or “4L” position. If you do turn suddenly, the
difference in turning speeds between the front and rear wheels may have
a similar effect to braking, thus making driving difficult.
● Do not shift the front-wheel drive control switch when the vehicle is turning
or when its wheels are spinning freely off the ground.

AUTO LSD system
The system can be used on 2WD models and in 2WD mode on 4WD
models.
Press the VSC off switch to turn
on the system.
At this time, the “AUTO LSD” and
VSC off indicators will come on
simultaneously.
To turn off the system, push the
switch again.
If the engine is turned off while the
“AUTO LSD” indicator is on and
then restarted, the indicator will
turn off automatically.
If the rear wheels spin, the slip
indicator flashes to indicate that
the AUTO LSD system has been
controlled the spinning of the rear
wheels.
The AUTO LSD system aids trac tion by using the traction con-
trol system to control engine performance and braking when
one of the rear wheels begins to spin.
The system should be used only when one of the rear wheels
spinning occurs in a ditch or rough surface.

■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 and TRAC systems will
turn on automatically 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. (There is no problem with con tinuing normal
driving.) The system will be automatically restored after a sho rt time.
WARNING
■ To avoid an accident
● Do not use the AUTO LSD system in conditions other than the abo ve.
A much greater steering effort and more careful cornering control will be
required.
● Do not drive with the AUTO LSD system continuously turned on.

3084-5. Using the driving support systems
Rear differential lock system
The rear differential lock system is effective in case one of t he rear
wheels is spinning.
Press the rear differential lock
switch to lock the rear differential.
At this time, the rear differential
lock indicator will blink. Wait a few
seconds for the system to com-
plete operation. After the rear dif-
ferential is locked, the indicator will
stop blinking and remain on.
To unlock the rear differential,
press the switch again.
Automatic transmission
4WD models: Before us ing the rear differential lock system.
Stop the vehicle, shift the shi ft lever to N and turn the front-wheel
drive control switch in the “4L” position 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 rear differential lock switch.
After the rear differential is locked, the indicator will come on.
Gently depress the accelerator pedal.
Unlock the rear differential as soon as the vehicle moves.
To unlock the rear different ial, press 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 sur -
face.

Manual transmission
Before using the rear differential lock system.
Stop the vehicle or reduce your speed to less than 2 mph (3 km/h).
Depress the clutch pedal and turn the front-wheel drive control
switch in the “4L” position to see if this is sufficient. If th is has no
effect, additionally use the re ar differential lock system.
Be sure to stop the wheels.
Depress the clutch pedal.
Press the rear differential lock switch.
After the rear differential is locked, the indicator will come on.
Slowly release th e clutch pedal.
Unlock the rear differential as soon as the vehicle moves.
To unlock the rear different ial, press the switch again.
■Locking the rear differential
●When the rear differential is locked, VSC is automatically turn ed off.
(The rear differential lock and VSC off indicators 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 indic ator to be on
at this time.
•ABS
• Multi Terrain ABS (if equipped)
• Brake assist system
•VSC
•TRAC
• Pre-Collision System (if equipped)
• Dynamic radar cruise control system (if equipped)
• Cruise control system (if equipped)
• Hill-start assist control (if equipped on 4WD models)
■ The rear differential lock is disengaged when
●Vehicles without a smart key system: When the engine switch is turned to
the “LOCK” position

■After unlocking the rear differential
Vehicles without a smart key system
To check that the indicator goes off, turn the engine switch to the “ON” posi-
tion, but do not start the engine.
Vehicles with a smart key system
To check that the indicator goes off, turn the engine switch to IGNITION ON

WARNING
■ 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 differential lock component parts.
● Do not drive over 5 mph (8 km/h) when the differential is locke d.
● Do not keep driving with the rear differential lock switch on.

■When the rear differential is locked (vehicles with the rear di fferential
lock system)
The active traction control system is activated only when the v ehicle speed is
less than 3 mph (6 km/h).
■ Sounds and vibrations caused by the active traction control sys tem
● A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound do es not indicate
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, a buzzer will sound to alert the driver. Stop
the vehicle in a safe place. (There is no problem with continuing normal driv-
ing.)
The system will be automatically restored after a short time.
WARNING
■ The active traction control system may 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 powe r may be lost.
