■Operating tips (vehicles with automatic transmission)
The system will operate when the shift lever is in a position other than P, how-
ever to make effective use of the system it is recommended to select a lower
shift range.
■ The system will not operate when
● The transfer mode is in H2.
● The rear differential is locked. (if equipped)
■ If the downhill assist control system indicator flashes
● In the following situations, the indicator flashes and the system will not oper-
ate:
• The transfer mode is not in L4 or H4.
• The rear differential is locked. (if equipped)
• The shift lever is in P. (vehicles with automatic transmission)
• The accelerator or brake pedal is depressed.
• The vehicle speed exceeds approximately 30 km/h (18 mph).
• The brake system overheats.
● In the following situations, the indicator flashes to alert the driver, but the
system will operate:
• The shift lever is in N. (vehicles with automatic transmission)
• The clutch pedal is depressed. (vehicles with manual transmission)
• The “DAC” switch is turned off while the system is operating.
The system will gradually ceases operat ion. The indicator will flash during
operation, and then go off when the system is fully off.
■ When the downhill assist control system is operated continuously
This may cause the brake actuator to overheat. In this case, the downhill
assist control system will stop operating, a buzzer will sound and the downhill
assist control system indicator will start flashing, and “TRC turned off” is
shown on the multi-information display. Refrain from using the system until
the downhill assist control system indicator stays on and “TRC turned off” dis-
played on the multi-information display goes out. (The vehicle can be driven
normally during this time.)
■ Sounds and vibrations caused by the downhill assist 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 downhill assist control system.
● Either of the following conditions may occur when the downhill assist control
system is operating. None of these are indicators that a malfunction has
occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.

■ System malfunction
In the following cases, have your vehicle checked by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
● The downhill assist control system indicator does not come on when the
engine switch is turned to the “ON” position (vehicles without smart entry &
start system) or IGNITION ON mode (vehicles with smart entry & start sys-
tem).
● The downhill assist control system indicator does not come on when the
“DAC” switch is pressed.
● The slip indicator comes on.
WARNING
■When using downhill assist control system
● Do not rely overmuch on the downhill assist control system. This function
does not extend the vehicle’s performance limitations. Always thoroughly
check the road conditions, and drive safely.
● Vehicles with manual transmission: Drive in a low gear. Driving in a high
gear when using downhill assist control system may cause the engine to
stall, which may lose the brake effectiveness and lock the tires, resulting in
an accident.
● Vehicles with manual transmission: On a steep slope, use the engine brak-
ing efficiently. If the vehicle is driven in N or with the clutch pedal
depressed on a steep slope, the load on the brake increases and con-
trolling the vehicle speed may be impossible, resulting in an accident.
■ The system may not operate on the following surfaces, which may lead
to an accident causing death or serious injury
● Slippery surfaces such as wet or muddy roads
● Icy surface
● Unpaved roads

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.

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.

Winter driving tips
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the condition of the battery.
● Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the rear tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
Perform the following according to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
● Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.

Driving
HILUX_OM_OM0K321E_(EE)
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions.
● Park the vehicle and move the shift lever to P (automatic transmis-
sion) or 1 or R (manual transmission) without setting the parking
brake. The parking brake may freeze up, preventing it from being
released. If the vehicle is parked without setting the parking brake,
make sure to block the wheels.
Failure to do so may be dangerous because it may cause the vehi-
cle to move unexpectedly, possibly leading to an accident.
● Vehicles with automatic transmission: If the vehicle is parked with-
out setting the parking brake, confirm that the shift lever cannot be
moved out of P*.
*: The shift lever will be locked if it is attempted to be shifted from P to any
other position without depressing the brake pedal. If the shift lever can be
shifted from P, there may be a problem with the shift lock system. Have the
vehicle inspected by any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
Use the correct tire chain size when mounting the snow chains.
Chain size is regulated for each tire size.
Regulations regarding the use of tire chains vary depending on loca-
tion and type of road. Always check local regulations before installing
chains.
