The use of undiluted windshield
washer concentrate or alco-
hol-based antifreeze can lead to
incorrect readings at tempera-
tures below +5°F/-15°C.This chapter describes all stan-
dard, country-specific and
optional features offered with
the series. It also describes fea-
tures and functions that are not
necessarily available in your
vehicle, e.g., due to the selected
options or country versions. This
also applies to safety-related
functions and systems. When
using these functions and sys-
tems, the applicable laws and
regulations must be observed.
The maintenance system pro-
vides service notifications and
thereby provides support in
maintaining road safety and the
operational reliability of the vehi-
cle.
In some cases, scopes and
intervals of the maintenance
system may vary according to
the country version. Replace-
ment work, spare parts, fuels
and lubricants, and wear materi-
als are calculated separately.
Further information is available
from a Toyota dealer.

ling effect on the windows can
lead to damage to the washing
system. There is a risk of damage
to property. Do not add sili-
con-containing additives to the
washer fluid.
NOTICE
Mixing different windshield
washer concentrates or antifreeze
can damage the washing system.
There is a risk of damage to prop-

determines the maintenance
recommendation using sensors
and special algorithms that take
into account the driving condi-
tions of the vehicle.
The system makes it possible to
adapt the amount of mainte-
nance corresponding to your
user profile.
Information on service notifica-
tions, refer to page 147, can be
displayed on the Control Dis-
play.
Storage periods during which
the vehicle battery was discon-
nected are not taken into
account.
If this occurs, have a Toyota
dealer update the time-depen-
dent maintenance procedures,
such as checking brake fluid
and, if necessary, changing the
engine oil and the microfil-
ter/activated-charcoal filter.Please consult “Owner's War-
ranty Information Booklet” or
“Owner's Manual Supplement”
for additional information on ser-
vice and maintenance work.
The manufacturer of your vehi-
cle recommends that mainte-
nance and repair be performed
by a Toyota dealer. Records of
regular maintenance and repair
work should be retained.
Scheduled maintenance should
be performed at specified inter-
vals according to the mainte-
nance schedule.
