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

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 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
sporty driving style, for instance
when taking curves aggres-
sively, regularly perform a
detailed measurement.
■Concept
The engine oil level is monitored
electronically while driving and
can be shown on the Control
Display.
If the engine oil level is outside
its permissible operating range,
a vehicle message is displayed.
■Functional requirements
A current measured value is
available after approx. 30 min-
utes of normal driving.

NOTICE
An engine oil level
that is too low

a risk of damage to property.
Immediately add engine oil.
NOTICE
Too much engine oil can damage
the engine or the catalytic con-
verter. There is a risk of damage
to property. Do not add too much
engine oil. When too much engine
oil is added, have the engine oil
level corrected by your Toyota
dealer.

■Displaying the engine oil
level
Via Toyota Supra Command:
1 "My Vehicle"
2 "Vehicle status"
3 "Engine oil level"
The engine oil leve l is displayed.
■System limits
When making frequent
short-distance trips or using a
sporty driving style, it may not
be possible to calculate a mea-
sured value. In this case, the
measured value for the last, suf-
ficiently long trip is displayed.
■Concept
The engine oil level is checked
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.
■General information
During the measurement, the
idle speed is increased some-
what.
■Functional requirements
• Vehicle is parked in a horizon- tal position.
• Manual transmission: gear- shift lever in idle position,
clutch and accelerator pedals
not depressed.
• Automatic transmission: selector lever in selector lever
position N or P and accelera-
tor pedal not depressed.
• Engine is running and is at operating temperature.
■Performing a detailed mea-
surement
Via Toyota Supra Command:
1 "My Vehicle"
2 "Vehicle status"
3 "Engine oil level"
4 "Measure engine oil level"
5 "Start measurement"
The engine oil level is checked
and displayed via a scale.
Only add engine oil when the
message is displayed in the
instrument cluster. The quantity
to be added is indicated in the
message shown on the Control
Display.
Only add suitable types of
engine oil, refer to page 304.
Safely park the vehicle and
switch off drive-ready state
before adding engine oil.
Take care not to add too much

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.

when it is just below the max-
imum mark in the filler neck.
Safety information
WARNING
With the engine hot and the cool-
ing system open, coolant can
escape and lead to scalding.
There is a risk of injury. Only open
the cooling system with the
engine cooled down.

Additives are harmful and incor-
rect additives can damage the
engine. There is a risk of injury
and risk of damage to property.
