CAUTION
■
General precautions while driving
Driving under the influence: Never drive your vehicle when under the influ-
ence of alcohol or drugs that have impaired your ability to operate your vehi-
cle. Alcohol and certain drugs delay reaction time, impair judgment and
reduce coordination, which could lead to an accident that could result in
death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistakes that other
drivers or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that
distracts the driver, such as adjusting controls, talking on a cellular phone or
reading can result in a collision with resulting death or serious injury to you,
your occupants or others.
■ General precaution regard ing children’s safety
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neut\
ral.
There is also a danger that children may injure themselves by playing with
the windows, the moon roof, or other features of the vehicle. In addition,
heat build-up or extremely cold temperatures inside the vehicle can be fatal
to children.

Ty p e A
The four-wheel drive indicator comes on when H4, N or L4 mode is
selected. H2 (high speed position, two-wheel drive)
Use this for normal driving on dry hard-surfaced roads. This position gives
greater economy, quietest ride and least wear.
H4 (high speed position, four-wheel drive)
Use this for driving only on tracks that permit the tires slide, like off-road,
icy or snow-covered roads. This position provides greater traction than
two-wheel drive.
N (neutral position)
No power is delivered to the wheels. The vehicle must be stopped.
L4 (low speed position, four-wheel drive)
Use this for maximum power and traction. Use “L4” for climbing or
descending steep hills, off-road driving, and hard pulling in sand, mud or
deep snow.
Four-wheel drive indicator

Use this for normal driving on dry hard-surfaced roads. This position gives
greater economy, quietest ride and least wear.
H4L (high speed position, center differential locked)
Use this for driving only on tracks that permit the tires slide, like off-road,
icy or snow-covered roads.
L4L (low speed position, center differential locked)
Use this for maximum power and traction. Use “L4L” for climbing or
descending steep hills, off-road driving, and hard pulling in sand, mud or
deep snow.

If the low speed four-wheel drive indicator continues to flash and a
buzzer sounds
The shift lever is not in N and/or the vehicle is moving. Stop the vehic\
le com-
pletely, shift the shift lever to N and make sure that the indicator stops flash-
ing.
■ If the low speed four-wheel drive indi cator or the center differential lock
indicator flashes rapidly
There may be a malfunction in the four-wheel drive system. Have the vehicle
inspected by your Toyota dealer immediately.
CAUTION
■ Operating the four-wheel drive control switch
Never operate the four-wheel drive control switch if the wheels have lost
traction. Doing so may cause an accident resulting in death or serious
injury.
Stop the wheels from slipping or spinning before operating the switch.
NOTICE
■ To prevent damage to the center differential
● For normal driving on dry and hard surface roads, unlock the center differ-
ential.
● Unlock the center differential after the wheels are out of the ditch or off the
slippery or bumpy surface.
● Do not lock or unlock the center differential when the vehicle is turning or
when its wheels are spinning freely off the ground.

drive control lever into L4.
Full-time 4WD models:
Stop the vehicle, shift the shift lever to N and then push and turn
the four-wheel drive control switch to L4L.
Press the “A-TRAC” switch to
activate the system.
At this time, the “A-TRAC” indi-
cator will come on.
To cancel the system, push the
switch again.

2444-5. Using the driving support systems
4RUNNER (U)_(OM35B37U)
If all wheels spin, the slip indicator
flashes to indicate that the active
traction control system has been
engaged.
■ When the rear differential is locked (vehicles with a rear differential lock
system)
The active traction control system is activated only when 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 indicate
that a malfunction has occurred in the system.
● Vibrations may be felt through the vehicle body and steering. This 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. At
this time, the “A-TRAC” indicator will go off and the “TRAC OFF” indicator will
come on. Stop the vehicle in a safe place. (There is no problem with continu-
ing normal driving.)
The system will be automatically restored after a short time.
When the active traction control system is operating
CAUTION
■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 operat\
ing.
Do not drive the vehicle in conditions where stability and power may be lost.

System operation
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, press the
switch again.
AUTO LSD system (2WD models)
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 wheel spinning occurs in
a ditch or rough surface.
