Always charge the battery in an open area. Do not charge the battery in a
garage or closed room w here there is insufficient ventilation.
■ How to recharge the battery (vehicles with maintenance-free type bat-
tery)
Only perform a slow charge (5 A or less). The battery may explode if
charged at a quicker rate.
■ Emergency measures regarding electrolyte
● If electrolyte gets in your eyes
Flush your eyes with clean water for at least 15 minutes and get immedi-
ate medical attention. If possible, continue to apply water with a sponge or
cloth while traveling to the nearest medical facility.

or Toyota authorized repairer, or any reliable repairer.
The water in the fuel filter needs to be drained if one of the following
symptoms occurs:
Vehicles without multi-information display
When the fuel system warning light flashes and a buzzer sounds.
( P. 604)
Vehicles with multi-information display

installing groove, and install the
fuel filter to the bracket as
shown in the illustration.
Operate the priming pump until

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. 554)
When refilling AdBlue™ by
yourself in an emergency, be
sure to follow the correct refill-
ing procedures. ( P. 555)

AdBlue™ is a trademark of the German Association of the Automotive
Industry (VDA).
● Before driving for a long period of time in an area where AdBlue™ cannot
be refilled, consult any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

Maintenance and care
■Refilling AdBlue™ by yourself in an emergency
When the engine cannot be restarted due to the depletion of
AdBlue™, adding approximately 5.0 L (5.3 qt., 4.4 Imp.qt.) or more

following procedures to refill AdBlue™. (The AdBlue™ tank has a
capacity of 13.8 L [14.6 qt., 12.1 Imp.qt.].)
Refilling with the refilling equipment
