WARNING
■TRC/A-TRC/VSC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC/A-TRC/VSC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.
■ Hill-start assist control does not operate effectively when
● Do not overly rely on the hill-start assist control. The hill-start assist control
may not operate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, the hill-start assist control is not intended to hold
the vehicle stationary for an extended period of time. Do not attempt to use
the hill-start assist control to hold the vehicle on an incline, as doing so
may lead to an accident.
■ When the TRC/VSC/Trailer Sway Control is activated
The slip indicator flashes. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the
indicator flashes.
■ When the TRC/A-TRC/VSC/Trailer Sway Control systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRC/A-TRC/VSC/Trailer Sway Control systems off
unless necessary.
■ Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC, A-TRC, VSC, Trailer Sway Control, hill-start assist control
and downhill assist control systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer for further information when replacing tires or wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

ceases operation, and will turn off when the system is fully off.
Press the “DAC” switch while the downhill assist control system indi-
cator is flashing to start the system again.
: If equipped
The downhill assist control system helps to prevent excessive
speed on steep downhill slopes.
The system will operate when the vehicle is traveling under
30 km/h (18 mph) and transfer mode is in L4 or H4.

■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

WARNING
■During regeneration
Observe the following precautions.
Failure to do so may result in serious injury such as burns caused by the hot
exhaust pipe and exhaust gases, or may cause a fire.
● Do not carry out regeneration when the vehicle is in an enclosed area,
such as a garage.
● Do not touch the exhaust pipe and exhaust gases during regeneration.
■ If the malfunction indicator lamp comes on
The malfunction indicator lamp comes on if you continue driving while the
DPF system warning light is flashing (v ehicles without multi-information dis-
play) or the DPF system warning message appears on the display (vehicles

vehicle or an accident may occur. Have the vehicle inspected by any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer
