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 indi-
cates required maintenance
measures, and thereby provides
support in maintaining road
safety and the operational reli-
ability of the vehicle.
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.

Sensors and special algorithms
take into account the driving
conditions of the vehicle. CBS
uses these to calculate the need
for maintenance.
The system makes it possible to
adapt the amount of mainte-
nance corresponding to your
user profile.
Information on service require-
ments, refer to page 141, 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 your "Owner's
Warranty Information Booklet"
or "Owner's Manual Supple-
ment" for additional information
on service requirements.
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.
For details about maintenance
items and schedules, refer to
the "Scheduled Maintenance
Guide" or "Owner's Manual Sup-
plement".
Devices connected to the OBD
socket trigger the alarm system

before locking the vehicle.
There is an OBD socket on the
driver's side for checking the pri-
mary components in the vehi-
cle's emissions. Safety information
NOTICE
The socket for Onboard Diagno-
sis is an intricate component
intended to be used in conjunction
with specialized equipment to
check the vehicle’s primary emis-
sions system. Improper use of the
socket for Onboard Diagnosis, or
contact with the socket for
Onboard Diagnosis for other than
its intended purpose, can cause
vehicle malfunctions and creates
risks of personal and property
damage. Given the foregoing, the
manufacture of your vehicle
strongly recommends that access
to the socket for Onboard Diagno-
sis be limited to your Toyota
dealer or other persons that have
the specialized
training and
equipment for purposes of prop-
erly utilizing the socket for
Onboard Diagnosis.

Emissions
• The warning light
lights up:
Emissions are deterio-
rating. Have the vehi-
cle checked as soon
as possible.
• The warning light flashes under certain
circumstances:
This indicates that
there is excessive mis-
firing in the engine.
Reduce the vehicle
speed and have the
system checked imme-
diately; otherwise, seri-
ous engine misfiring
within a brief period
can seriously damage
emission control com-
ponents, in particular
the catalytic converter.

Lights and bulbs make an
essential contribution to vehicle
safety.
All headlights and lights are
made using LED technology.
Some items of equipment use
light-emitting diodes installed
behind a cover as a light source.
These light-emitting diodes are
related to conventional lasers
and are officially designated as
Class 1 light-emitting diodes.
The manufacturer of the vehicle
recommends that you let your
Toyota dealer perform the work
in case of a malfunction. Condensation can form on the
inside of the headlight glass in
cool or humid weather. When
driving with the lights switched
on, the condensation evapo-
rates after a short time. The
headlight glass does not need to
be changed.
If despite driving with the head-
lights switched on, increasing
humidity forms, for instance
water droplets in the light, have
the headlights checked.
The battery is maintenance-free.
