■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.

WARNING
■When the Stop & Start system is operating
● Keep the shift lever in N (manual transmission), depress the brake pedal
and apply the parking brake when necessary while the engine is stopped
by the Stop & Start system (while the Stop & Start indicator is on).
● Do not allow anyone to leave the vehicle while the engine is stopped by
the Stop & Start system (while the Stop & Start indicator is on).
An accident may occur due to the automatic engine start function.
● Ensure that the engine is not stopped by the Stop & Start system while the
vehicle is in a poorly ventilated area. The engine may restart due to the
automatic engine start function, causing exhaust gases to collect and
enter the vehicle, possibly resulting in death or a serious health hazard.
■ Off-road driving precaution
When driving off-road, such as driving through water, press the Stop & Start
cancel switch to disable the Stop & Start system. Failure to do so may
cause the engine to be unable to restart.
NOTICE
■ To ensure the system operates correctly
If any of the following situations occur, the Stop & Start system may not
operate correctly. Have your vehicle inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
● While the driver’s seat belt is fastened, the driver’s and front passenger’s
seat belt reminder light flashes.
● Even though the driver’s seat belt is not fastened, the driver’s and front
passenger’s seat belt reminder light does not illuminate.
● Even though the driver’s door is closed, the open door warning is dis-
played on the multi-information display or the interior light is illuminated
when door linked illumination is enabled ( P. 538).
● Even though the driver’s door is open, the open door warning is not dis-
played on the multi-information display or the interior light does not illumi-
nate when door linked illumination is enabled ( P. 538).

■ Sounds and vibrations caused by the ABS, brake assist, VSC, Trailer
Sway Control, TRC, A-TRC and the hill-start assist control systems
● A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine is started or just after the vehicle
begins to move. This sound does not indicate that a malfunction has
occurred in any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard also after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.

systems
After turning the TRC, A-TRC, VSC and Trailer Sway Control systems off, the
systems will be automatically re-enabled in the following situations:
● When the engine switch is turned to the “LOCK” position (vehicles without
smart entry & start system) or off (vehicles with smart entry & start system).
● If only the TRC/A-TRC system is turned off, the TRC/A-TRC will turn on
when vehicle speed increases.
If the TRC, A-TRC, VSC and Trailer Sway Control systems are turned off,
automatic re-enabling will not occur when vehicle speed increases.
■ Operating conditions of the hill-start assist control
When the following four conditions are me t, the hill-start assist control will
operate:
● Vehicles with automatic transmission: The shift lever is in a position other
than P or N (when starting off forward/backward on an upward incline)
Vehicles with manual transmission: The shift lever is in a position other than
R when starting off forward on an upward incline, or the shift lever is in R
when starting off backward on an upward incline.
● The vehicle is stopped
● The accelerator pedal is not depressed
● The parking brake is not engaged
■ Automatic system cancelation of the hill-start assist control
The hill-start assist control will turn off in any of the following situations:
● Vehicles with automatic transmission: The shift lever is shifted to P or N
Vehicles with manual transmission: The shift lever is shifted to R when start-
ing off forward on an upward incline, or the shift lever is shifted to other than

DPF (Diesel Particulate Filter) system
◆Regeneration
Regeneration is performed as necessary in accordance with driving
conditions.
◆System characteristics
The DPF system has the following characteristics:
● Idle speed increases during regeneration
● The smell of the exhaust gas differs from that of a conventional
diesel vehicle
● White smoke may be emitted from the exhaust pipe during
regeneration. However, this does not indicate a malfunction.
● If the DPF system warning light turns on (vehicles without multi-
information display) or the DPF system warning message “DPF
FULL MANUAL REGENERATION REQUIRED SEE OWNER’S
MANUAL”/“DPF full Manual regeneration required See owner’s
manual” appears on the display (vehicles with multi-information dis-
play), follow the procedure below to regenerate.
Stop the vehicle in a safe place.
Shift the shift lever to P (automatic transmission) or N (manual
transmission), and firmly set the parking brake.
Do not stop the engine.
Also, make sure that there are no flammable materials near the exhaust
pipe. ( P. 436)
Check the engine is warmed up. If the engine is cold, warm up the engine
by depressing the accelerator pedal.*1
: If equipped
When the deposit collected by the filter reaches a predetermined
amount, it is automatically regenerated.

HILUX_OM_OM0K321E_(EE)
Press the DPF system switch.
Vehicles without multi-information display
The DPF system warning light will change from solid to slow flashing, and
the idling engine speed will increase.
Vehicles with multi-information display
The DPF system warning message
shown in the illustration appears
on the display, and the idling
engine speed will increase.
Regeneration will take around 30 - 40 minutes to complete.*2
When the DPF system warning light or the DPF system warning mes-
sage goes out, the idling engine speed will have finished returning to
normal.
The DPF system switch may not operate when the vehicle is higher
than 4000 m (13123 ft.) above sea level.
*1: Depending on the situation, it may be necessary to depress the accelera-
tor pedal until the engine speed is increased to 3000 rpm. If the engine
coolant temperature or exhaust gas tem perature is low, it may take a long
time to regenerate, or regeneration may be impossible.
*2: Time required for regeneration differs in accordance with the outside tem-
perature. Also, if the engine speed is still approximately 2000 rpm 10 min-
utes after pressing the DPF system switch, the exhaust gas temperature
may be low. In this case, depress the accelerator pedal to run the engine
at approximately 3000 rpm for a while.
When depressing the accelerator pedal, regeneration will be stopped. In
this case, restart regeneration.
