steps and again.
If the clutch pedal is released while the low speed four-wheel drive indi-
cator light is flashing, gear noise may be caused. Immediately depress
the clutch pedal firmly and wait until switching the transfer mode is com-
pleted.
Check that the low speed

NOTICE
■ Shifting between H4 and L4
Do not release the clutch pedal or depress the accelerator pedal while the
low speed four-wheel drive indicator light is flashing. Failure to do so may
cause gear noise and result in a malfunction.

■Four-wheel drive usage frequency (vehicles with A.D.D.)
You should drive in four-wheel drive for at least 16 km (10 miles) each month.
This will assure that the front drive components are lubricated.
■ Shifting between H2 and H4
If you have trouble shifting in cold w eather, reduce your speed or stop the
vehicle and reshift.
■ Shifting to L4 (vehicles with VSC)
VSC is automatically turned off.
■ When driving on dry paved surface roads and expressway
Use H2 position. If the vehicle is driven in H4 or L4 position for a long time, a
warning buzzer sounds, and the four-wheel drive indicator light flashes rap-
idly or a warning message is shown on the multi-information display. If the
warning message is shown on the multi-information display, follow the mes-
sage.
WARNING
■ While driving
● Never turn the front-wheel drive control switch from H2 to H4 if the wheels
are slipping. Stop the slipping or spinning before shifting.
● For normal driving on dry and hard surface roads, use H2 position. Driving
on dry and hard surface roads in H4 or L4 position may cause drive com-
ponent oil leakage, seizure, or other problems resulting in an accident.
Further, it may cause tire wear and increased fuel consumption.
● Avoid turning suddenly in H4 or L4 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.

Rear differential lock system
Press the rear differential lock
switch to lock the rear differential.
The rear differential lock indicator
comes on.
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 ragged sur-
face.
This differential lock system is effective in case one of the rear
wheels is spinning.

HILUX_OM_OM0K375E_(EE)
4WD models only: Before using
the rear differential lock system,
turn the front-wheel drive con-
trol switch to L4 and try to move
the vehicle. ( P. 366, 369)
If this is not sufficient, use the rear
differential lock system as well.
Reduce the vehicle speed to
less than 8 km/h (5 mph).
Make sure that the wheels are not
spinning.
Press the rear differential lock
switch.
The rear differential lock indicator

switch without following steps
and , the rear differential lock
indicator flashes three times and a
buzzer sounds three times, and the
rear differential cannot be locked.
Try steps and again.

■Locking the rear differential
The following systems do not operate w hen the rear differential is locked.
It is normal operation for the ABS warning light, VSC OFF indicator (if
equipped) and “TRC OFF” indicator (if equipped) to be on or for “TRC
TURNED OFF”/“TRC turned off” to be displayed on the multi-information dis-
play (if equipped) at this time.
•ABS
• Brake assist (if equipped)
• VSC (if equipped)
• TRC/A-TRC (if equipped)
• Trailer Sway Control (if equipped)
• Hill-start assist control (if equipped)
• Downhill assist control (if equipped)
■ Unlocking the rear differential
If the rear differential lock indicator still flashes even after unlocking the rear
differential, check the safety of the surrounding area and slightly turn the
steering wheel in either direction while the vehicle is in motion.
■ Automatic system cancelation of the rear differential lock system
The rear differential lock is also unlocked in any of the following situations:
● The front-wheel drive control switch is turned to H2 or H4 (4WD models)
● The engine switch is turned to the “ACC” or “LOCK” position (vehicles with-
out smart entry & start system) or A CCESSORY or off (vehicles with smart
entry & start system)
■ After unlocking the rear differential
Check that the indicator goes off.
WARNING
■ To avoid an accident
Failure to observe the following precautions may result in an accident.
● Do not use the rear differential lock system except when wheel spinning
occurs in a ditch or on a slippery or rugged 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 8 km/h (5 mph) when the differential is locked.
● Do not keep driving with the rear differential lock switch on.

Stop & Start system (Smart Stop)
■Stopping the engine
Vehicles with automatic
transmission
While driving with the shift lever
in D or S, depress the brake
pedal, and stop the vehicle.
The Stop & Start indicator will
come on.
Vehicles with manual trans-
mission
Stop the vehicle with the clutch pedal fully depressed, shift the shift
lever to N, and release the clutch pedal.
The Stop & Start indicator will come on.
■Restarting the engine
Vehicles with automatic transmission
Release the brake pedal.
The Stop & Start indicator will go off.
Vehicles with manual transmission
Check that the shift lever is in N and depress the clutch pedal.
The Stop & Start indicator will go off.
: If equipped
The Stop & Start system stops and restarts the engine according
to the brake pedal operation (automatic transmission) or clutch
pedal operation (manual transmission) for stopping and starting
the vehicle.
Stop & Start system operation

3784-5. Using the driving support systems
HILUX_OM_OM0K375E_(EE)
Press the Stop & Start cancel
switch to disable the Stop & Start
system.
The Stop & Start cancel indicator
will come on.
Pressing the switch again will
enable the Stop & Start system and
the Stop & Start cancel indicator
will turn off.
■Automatic reactivation of the Stop & Start system
Even if the Stop & Start system is disabled by the Stop & Start can-
cel switch, it will be automatically re-enabled once the engine
switch is turned to the “LOCK” position (vehicles without smart
entry & start system) or off (vehicles with smart entry & start sys-
tem), and then the engine is started.
■If the Stop & Start cancel switch is pressed while the vehicle is
stopped
● When the engine is stopped by the Stop & Start system, pressing
the Stop & Start cancel switch will restart the engine.
From the next time the vehicle is stopped (after Stop & Start sys-
tem has been turned off), the engine will not be stopped.
● With the Stop & Start system disabled, pressing the Stop & Start
cancel switch will re-enable the system but not stop the engine.
From the next time the vehicle is stopped (after Stop & Start sys-
tem has been turned on), the engine will be stopped.
If the engine is stopped by the Stop & Start system when the vehicle is
on an incline, brake force is temporarily maintained to prevent rolling
backwards until the engine is restarted and drive force is generated.
When drive force is generated, the maintained brake force is automat-
ically canceled.
● This function operates on flat surfaces as well as steep incline.
● Sound may be generated by the brakes, but this is not a malfunc-
tion.
● The brake pedal response may change and vibration may occur,
but these are not malfunctions.
