■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.

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.

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.

operate correctly. Have your vehicle inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.

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).
