steering wheel will be locked due to the steering lock function. Operating the
engine switch again automatically cancels the steering lock.
■ When the steering lock cannot be released
■ Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the engine is turned on and off repeatedly in a short period of time.
In this case, refrain from running the engine. After about 10 seconds, the
steering lock motor will resume functioning.
■ If “SMART ENTRY & START SYSTEM MALFUNCTION SEE OWNER’S
MANUAL”/“Smart Entry & Start System malfunction See owner’s man-
ual” is shown on the multi-information display (if equipped)
The system may be malfunctioning. Have the vehicle inspected by any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer
immediately.

HILUX_OM_OM0K375E_(EE)
■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.
