The engine oil consumption is
dependent on your driving style
and driving conditions.
Therefore, regularly check the
engine oil level after refueling by
taking a detailed measurement.
The engine oil consumption can
increase in the following situa-
tions, for example:
• Sporty driving style.
• Break-in of the engine.
• Idling of the engine.
• With use of engine oil types that are classified as not suit-
able.
Different vehicle messages
appear on the Control Display
depending on the engine oil level.
The electronic oil measurement
has two measuring principles:
• Monitoring.
• Detailed measurement.
When making frequent
short-distance trips or using a
dynamic driving style, for
instance when taking curves
aggressively, regularly perform
a detailed measurement.
The engine oil level is monitored

when the vehicle is stationary
and displayed via a scale.
If the engine oil level is outside
its permissible operating range,
a vehicle message is displayed.

Coolant consists of water and
additives.
Not all commercially available
additives are suitable for the
vehicle. Do not mix additives of
different colors. Observe the
water - additive mixing ratio of
50:50. Information about suit-
able additives is available from
your Toyota dealer. Vehicles with gasoline engine
feature two cooling circuits.
Always check the coolant levels
of both coolant reservoirs and
refill as needed.
The coolant level is indicated
using the Max mark in the filler
neck of the coolant reservoir.
Depending on the engine instal-
lation, the coolant reservoir is
located on the right side or the
left side of the engine compart-
ment, refer to page 299.

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. 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 notifica-
tions, refer to page 145, 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.

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.
