This chapter describes all stan-
dard, country-specific and
optional features offered with
the series. It also describes fea-
tures that are not necessarily
available in your vehicle, for
instance, 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.
Depending on the region, many
gas stations sell fuel that has
been customized to winter or
summer conditions. Fuel that is
available in winter,for instance
helps make a cold start easier.
For the best fuel consumption,
the gasoline should be sul-
fur-free or very low in sulfur con-
tent.
Fuels that are marked on the gas pump as containing metal
must not be used.
Fuels with a maximum ethanol
content of 25 %, i. e. E10 or
E25, may be used for refueling.
To achieve nominal values for
mileage and consumption, fol-
low the specified fuel quality in
the sales literature.
Ethanol should meet the follow-
ing quality standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: comply with the current valid
standard in each case.
The use of fuels of minimum
quality has no influence on the
service life of the engine.

Refuel with this gasoline to
achieve the rated performance
and consumption values.
The minimum grade is AKI 87.
If you use gasoline with this min-
imum AKI Rating, the engine
may produce knocking sounds
when starting at high external
temperatures. This has no effect
on the engine life.

WARNING
If drivability prob lems are encoun-
tered, we recommend switching
to a high quality gasoline brand
and a higher octane grade - AKI
number - for a few tank fills. To
avoid harmful engine deposits, it
is highly recommended to pur-
chase gasoline from Top Tier
retailers.
Failure to comply with these rec-
ommendations may result in the
need for unscheduled mainte-
nance.
NOTICE
Even small quantities of the
wrong fuel or wrong fuel additives
can damage the fuel system and
engine. Furthermore, the catalytic
converter is permanently dam-
aged. There is a risk of damage to
property. Do not refuel or add the
following in the case of gasoline
engines:

mercially available additives are
suitable for the vehicle. The
vehicle manufacturer recom-
mends using coolant with the
BMW LC-18 specification. Do
not mix additives of different col-
ors. Observe the water - additive
mixture ratio of 50:50. Informa-
tion about suitable additives is
available from your Toyota
dealer.
Depending on the motorization,
there are up to two coolant res-
ervoirs in the engine compart-
ment. Check and top up the
coolant levels on a regular
basis.The coolant may be overfilled in
the coolant reservoir when the
vehicle is delivered from the fac-
tory. The normal coolant level is
achieved by operating the vehi-
cle for a longer period.
The coolant level is indicated
using the maximum mark in the
filler neck of the coolant reser-
voir.

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

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.
Follow the safety information,
refer to page 312.
