Engine oil consumption depends on
the driving style and operating con-
ditions.
Therefore check the engine oil level
regularly each time you fill up with
fuel by taking a detailed measure-
ment.
Engine oil consumption can be
increased, for example in the fol-
lowing situations:
• Sporty driving style.
• Running in the engine.
• Engine idling.
• Use of engine oil grades catego-
rised as unsuitable.
Different vehicle messages are
shown on the Control Display,
depending on the engine oil level.
NOTICE
After filling the wrong fuel, do not
press the start/stop button. Contact
any authorized Toyota retailer or Toyota authorized repairer, or any reli-
able repairer.
NOTICE
Incorrect fuels can damage the fuel
system and engine. There is a danger of damage to property. Do not refuel
with fuel with a higher ethanol content
than recommended. Do not refuel with fuel containing methanol, for
example M5 to M100.
NOTICE
Fuel below the specified minimum quality can adversely affect engine
function or lead to engine damage.
There is a danger of damage to prop- erty. Do not refuel with petrol below
the specified minimum quality.

Electronic oil measurement uses
two measuring methods:
• Monitoring.
• Detailed measurement.
When frequently making short trips
or using a sporty driving style, for
example taking corners at high
speed, regularly perform a detailed
measurement.
■Principle
The engine oil level is electronically
monitored during the journey and
can be shown on the Control Dis-
play.
If the engine oil level is outside its
permissible operating range, a
vehicle message is shown.
■Operating requirements
A current measurement is available
after approximately 30 minutes of
normal driving.
■Displaying the engine oil level
Via Toyota Supra Command:
1 "My Vehicle"
2 "Vehicle status"
3 "Engine oil level"
The engine oil level is displayed.
■System limits
When frequently making short trips
or using a sporty driving style, it
may not be possible to measure the
oil level. In this case, the measure-
ment for the last, sufficiently long
journey is displayed.
■Principle
The engine oil level is checked
when the vehicle is stationary and
is shown on a scale.
If the engine oil level is outside its
permissible operating range, a
vehicle message is shown.
■General
During measurement, the idle
speed is slightly raised.
■Operating requirements
• Vehicle is standing horizontally.
• Selector lever in selector lever
position N or P and accelerator
pedal not pressed.
• Engine is running and is at oper-
NOTICE
Too much engine oil can damage the
engine or the catalytic converter.
There is a danger of damage to prop- erty. Do not top up with too much
engine oil. If there is too much engine
oil, have the engine oil level corrected by any authorized Toyota retailer or
Toyota authorized repairer, or any reli-
able repairer.

Some antifreezes can contain toxic
substances, and are flammable. There is a risk of fire and fatal injury.
Please comply with the instructions
on the containers. Keep antifreezes away from sources of combustion. Do
not pour service products into other
bottles. Keep service products out of

Washer fluid can ignite on contact
with hot parts of the engine and catch fire. There is a danger of injury or
damage to property. Only top up
washer fluid when the engine has cooled down. Then fully close the cap
of the washer fluid reservoir.
NOTICE
Additives containing silicone added to the washer fluid for their water bead-
ing effect on the windows may dam-
age the washer system. There is a danger of damage to property. Do not
add any additives containing silicone
to the washer fluid.
NOTICE
Mixing different screenwash concen-
trates or antifreezes can result in

This chapter describes all standard,
country-specific and special equip-
ment available for the model series.
It may therefore describe equip-
ment and functions which are not
installed in your vehicle, for exam-
ple on account of the special equip-
ment selected or the country
specification. This also applies to
safety-relevant functions and sys-
tems. Please comply with the rele-
vant laws and regulations when
using the corresponding functions
and systems.
The maintenance system indicates
what maintenance measures are
required and thereby assists in
maintaining the road safety and
operational safety of the vehicle.
The exact work required and the
maintenance intervals may vary
depending on the country specifica-
tions. Replacement work, spare
parts, operating materials and wear
materials are calculated sepa-
rately. Additional information is
available from a dealer of the man-
ufacturer or another qualified dealer
or a specialist workshop.
Condition Based Service CBS
determines the maintenance
requirement using sensors and
special algorithms which monitor
the conditions in which the vehicle
is used.
The system thus enables the scope
of the maintenance work to be
adapted to the individual usage
profile.
Information on service require-
ments, see page 170, can be
shown on the Control Display.
Periods when the vehicle is out of
use with its battery disconnected
are not taken into account.
In such cases, have any
time-dependent maintenance pro-
cedures, for example for the brake
fluid and, where applicable, the
engine oil and microfilter/activated
charcoal filter, updated by a dealer
of the manufacturer or another
qualified dealer or a specialist
workshop.
