QFour-wheel drive usage frequency (vehicles with A.D.D.)
You should drive in four-wheel drive for at least 16 km (10 miles) each month.
This will assure that the front drive components are lubricated.
Q Shifting between H2 and H4
If you have trouble shifting in cold w eather, reduce your speed or stop the
vehicle and reshift.
Q Shifting to L4 (vehicles with VSC)
VSC is automatically turned off.
Q When driving on dry paved surface roads and expressway
Use H2 position. If the vehicle is driven in H4 or L4 position for a long time, a
warning buzzer sounds, and the four-wheel drive indicator light flashes rap-
idly or a warning message is shown on the multi-information display. If the
warning message is shown on the multi-information display, follow the mes-
sage.
WARNING
Q While driving
O Never turn the front-wheel drive control switch from H2 to H4 if the wheels
are slipping. Stop the slipping or spinning before shifting.
O For normal driving on dry and hard surface roads, use H2 position. Driving
on dry and hard surface roads in H4 or L4 position may cause drive com-
ponent oil leakage, seizure, or other problems resulting in an accident.
Further, it may cause tire wear and increased fuel consumption.
O Avoid turning suddenly in H4 or L4 position. If you do turn suddenly, the
difference in turning speeds between the front and rear wheels may have
a similar effect to braking, thus making driving difficult.

QLocking 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” to be displayed on the multi-information display (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)
Q 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.
Q Automatic system cancelation of the rear differential lock system
The rear differential lock is also unlocked in any of the following situations:
O The front-wheel drive control switch is turned to H2 or H4 (4WD models)
O 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)
Q After unlocking the rear differential
Check that the indicator goes off.
WARNING
Q To avoid an accident
Failure to observe the following precautions may result in an accident.
O 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.
O 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.
O Do not drive over 8 km/h (5 mph) when the differential is locked.
O Do not keep driving with the rear differential lock switch on.

When the engine is stopped by the Stop & Start system when the
vehicle is on an incline, when the brake pedal is released, brake force
is temporarily maintained to prevent the vehicle from rolling back-
wards before the engine is restarted and drive force is generated.
When drive force is generated, the maintained brake force is automat-
ically canceled.
O This function operates on flat surfaces as well as steep inclines.
O Sound may be generated from the brake system, but this does not
indicate a malfunction.
O Brake pedal response may change and vibration may occur, but
this does not indicate a malfunction.
Q Points for use
O If the engine switch is pressed when the engine is stopped by the Stop &
Start system, the engine will not be able to be restarted by the automatic
engine start function. In this case, restart the engine using the normal
engine starting procedure. ( P. 220, 223)
O When the engine is being restarted by the Stop & Start system, the power
outlets may be temporarily unusable, but this does not indicate a malfunc-
tion.
O Installation and removal of electrical components and wireless devices may
affect the Stop & Start system. Contact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer for details.
O When stopping the vehicle for a longer period of time, turn the engine switch
to the “LOCK” position*1 or off*2 to stop the engine completely.
O When the engine is restarted by the Stop & Start system, the steering wheel
may temporarily feel heavy.
O 4WD models only: While driving in L4 mode, it is recommended that the
Stop & Start system be canceled because the system may not operate prop-
erly.
