■Four-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.
■ Shifting between H2 and H4
If you have trouble shifting in cold w eather, reduce your speed or stop the
vehicle and reshift.
■ Shifting to L4 (vehicles with VSC)
VSC is automatically turned off.
■ 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.
■ If “DIFFERENTIAL OIL TEMP HIGH SHIFT TO 2WD MODE COOLING TIME
REQUIRED”/“Differential oil temp high Shift to 2WD mode Cooling time
required” is shown on the multi-info rmation display (vehicles with multi-
information display)
The differential oil temperature is too high.
Turn the front-wheel drive control switch to H2, and wait until the warning
message goes off.
WARNING
■ While driving
● Never turn the front-wheel drive control switch from H2 to H4 if the wheels
are slipping. Stop the slipping or spinning before shifting.
● 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.
● 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.

WARNING
■When the Emergency Call may not be made
●It may not be possible to make Emergency Calls in any of the following sit-
uations. In such cases, report to emergency services provider (112 system
etc.) by other means such as nearby public phones.
• Even when the vehicle is in the cellular phone service area, it may be
difficult to connect to the ERA-GLONASS/EVAK control center if the
reception is poor or the line is busy. In such cases, even though the sys-
tem attempts to connect to the ERA-GLONASS/EVAK control center,
you may not be able to connect to the ERA-GLONASS/EVAK control
center to make Emergency Calls and contact emergency services.
• When the vehicle is out of the cellular phone service area, the Emer-
gency Calls cannot be made.
• When any related equipment (such as the “SOS” button panel, indicator
lights, microphone, speaker, DCM, antenna, or any wires connecting
the equipment) is malfunctioning, damaged or broken, the Emergency
Call cannot be made.
• During an Emergency Call, the system makes repeated attempts to
connect to the ERA-GLONASS/EVAK control center. However, if it can-
not connect to the ERA-GLONASS/EVAK control center due to poor
radio wave reception, the system may not be able to connect to the cel-
lular network and the call may finish without connecting. The red indica-
tor light will blink for approximately 30 seconds to indicate this
disconnection.
• This device may not function if a shock is applied to it.
●If the battery’s voltage decreases or there is a disconnection, the system
may not be able to connect to the ERA-GLONASS/EVAK control center.

Maintenance and care
AdBlue™ is used to reduce the amount of nitrogen oxides in exhaust
gas. AdBlue™ is consumed in the process of driving. Therefore,
observe the following precautions.
● 1.0 L (1.1 qt., 0.9 Imp.qt.) of AdBlue™ is consumed every 1500 km
(932 miles). Normally, after a full refill, the vehicle can be driven for
approximately 15000 km (9321 miles) before all AdBlue™ is
depleted.
However, AdBlue™ may become completely depleted sooner
depending on driving conditions.
● When the possible driving range based on the remaining amount of
AdBlue™ reaches approximately 2400 km (1492 miles), the low
AdBlue™ level warning light turns on and a warning message is
displayed.
● When AdBlue™ is depleted, the engine cannot be restarted.
● If AdBlue™ is accidentally spilled while refilling, vehicle parts, paint,
etc. may be damaged.
When AdBlue™ needs to be refilled, have it refilled at any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
It may be a criminal offence to use a vehicle that does not consume
any reagent if it is required for the reduction of emissions.
■AdBlue™ warning light and warning message
When the AdBlue™ level is low,
the low AdBlue™ level warning
light turns on and a warning
message appears on the multi-
information display. ( P. 562)
When refilling AdBlue™ by
yourself in an emergency, be
sure to follow the correct refill-
ing procedures. ( P. 563)
