Noise, for example caused by
the radiator fan running, even
some minutes after stopping the
engine.
It is normal for the radiator fan to
keep running for several minutes,
even after short trips.
Various driver profiles ensure that
the exhaust gas particle filter is
self-cleaning. If, in addition to the
self-cleaning function, the exhaust
gas particle filter needs to be
actively cleaned while driving, a
vehicle message is displayed.
Proceed as follows the next time
you drive outside of built-up areas
for around 30 minutes:
Deactivate Cruise Control sys-
tems.
Take your foot off the accelerator
repeatedly and allow the vehicle
to roll in overrun mode, see page
273.
If possible, drive at alternating
speeds.Cleaning the exhaust gas

WARNING
Certain vehicle functions may be
affected by interference from high-fre-
quency radio signals. Such signals
originate from various transmitter sys-
tems, for example, from air traffic bea-
cons or relay stations for mobile
telecommunications.
We recommend you consult any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer should you experience any
difficulties in this regard.
Mobile communication in the
vehicle
WARNING
There is a possibility of reciprocal
interference between the vehicle elec-
tronics and mobile radio devices.
Radiation is generated when mobile
radio devices are transmitting. There
is a danger of injury or damage to
property. If possible, only use mobile
radio devices, for example mobile
telephones, in the interior if they are
connected directly to an external
antenna in order to eliminate recipro-
cal interference and to dissipate the
radiation from vehicle's interior.

Supra Owner's Manual4-1. DRIVING HINTS
This situation, known as aquaplan-
ing, means that the tyre can actu-
ally lose contact completely with
the road surface and the vehicle
can neither be steered, nor the
brakes properly applied.
Please comply with the following
when driving through water:
Only drive through still water.
Only drive through water up to a
max. depth of 25 cm, 9.8 in.
Drive through water at a walking
speed of no more than 5 km/h, 3
mph.
The vehicle is equipped with the
Anti-lock Brake System ABS as
standard.
Perform full braking in situations that require it.
The vehicle remains steerable. Any
obstacles can be avoided by per-
forming steering movements as
smoothly as possible.
A pulsing of the brake pedal and
hydraulic regulating sounds indi-
cate that the Anti-lock Brake Sys-
tem ABS is regulating.
In certain braking situations, the
perforated brake discs can cause
functional noise. However, func-
tional noises have no effect on the
efficiency and operational safety of
the brakes.
In damp weather, on gritted roads
and in heavy rain, apply the brakes
lightly every few kilometres/miles. Driving through water
General
Safety note
NOTICE
Driving through excessively deep
water too fast can result in water
entering the engine compartment,
electrical system or transmission.
There is a danger of damage to prop-
erty. When driving through water, do
not exceed the maximum water depth
and speed specified above.
Safe braking
General
Objects in the range of movement
of the pedals
WARNING
Objects in the driver's footwell can
restrict the pedal travel or block a
pedal that has been pressed. There is
a danger of accidents. Stow items in
the vehicle so that they are secure
and cannot get into the driver's
footwell. Only use floor mats that are
suitable for the vehicle and can be
securely fastened to the floor. Do not
use loose floor mats, and do not place
several floor mats on top of one
another. Make sure that there is suffi-
cient space for the pedals. Ensure
that floor mats are securely reat-
tached after having been removed, for
example for cleaning.

DRIVING HINTS
Ensure that you do not obstruct
other road users when doing so.
The heat generated by braking
dries the brake discs and brake
pads and protects them against
corrosion.
This way, brake power is available
immediately, whenever it is needed.
■General
When driving on long or steep
downhill stretches, use the gear in
which the least braking is required.
Otherwise the brake system can
overheat and the braking effect is
reduced.
Engine braking effect can be addi-
tionally increased by manually shift-
ing down, even into first gear, if
applicable.
■Safety notesCorrosion of the brake discs and
contamination of the brake pads
increase in the following circum-
stances:
Low mileage.
Extended periods when the vehi-
cle is not used.
Infrequent use of the brakes.
Aggressive, acidic or alkaline
cleaning agents.
Should corrosion form on the brake
discs, the brakes will tend to
respond with a judder effect that
generally cannot be eliminated.
When the automatic air condition-
ing is in operation, condensation
develops and exits underneath the
vehicle.
The higher mechanical and thermal
loads involved in driving on racing Downhill gradients
WARNING
Even slight continuous pressure on
the brake pedal can cause overheat-
ing, brake pad wear or even brake
system failure. There is a danger of
accidents. Avoid excessive loads on
the brake.
WARNING
When idling or with the engine
switched off, safety-relevant func-
tions are restricted or no longer avail-
able, for example the braking effect of
the engine or power assistance for
the braking force and steering. There
is a danger of accidents. Do not drive
at idle speed or with the engine
switched off.

Add-on parts on the vehicle inter-
fere with its aerodynamic perfor-
mance and increase fuel
consumption.
Open windows increase drag and
consequently fuel consumption.
Tyres can have differing effects on
consumption. For example, con-
sumption can be affected by tyre
size.
Check and, if necessary, correct the
tyre inflation pressures at least
twice a month and before setting off
on a longer journey.
Insufficient tyre inflation pressure
increases rolling resistance and
consequently fuel consumption and
tyre wear.
Do not warm up the engine with the
vehicle at a standstill; it is prefera-
ble to set off straight away, driving
at moderate engine speeds.This brings the cold engine up to
operating temperature as quickly as
possible.
Anticipating the road situation and
adopting a smooth driving style will
reduce fuel consumption.
Avoid accelerating and braking
unnecessarily.
Keep an appropriate distance from
the vehicle ahead.
Driving at low engine speeds
reduces fuel consumption and
wear.
Pay attention to the shift point indi-
cator, see page 160, in the vehicle,
if fitted.
When approaching a red traffic
light, take your foot off the accelera-
tor and allow the vehicle to roll.
On downward stretches, take your
foot off the accelerator and allow
the vehicle to roll.
The fuel supply is interrupted in
overrun mode. Remove add-on parts after
use

Supra Owner's Manual4-1. DRIVING HINTS
When you stop the vehicle for
longer periods, for example at traf-
fic lights, railway crossings or in
traffic jams, switch off the engine.
The Auto Start/Stop of the vehicle
shuts off the engine automatically
during a stop.
If the engine is switched off and
then started again, the fuel con-
sumption and emissions are
reduced compared with a perma-
nently running engine. Savings can
be made just by stopping the
engine for a few seconds.
Fuel consumption also depends on
other factors, such as driving style,
road condition, maintenance or
environmental factors, for example.
Functions such as seat heating or
rear window heating require a great
deal of energy and increase fuel
consumption, especially in city traf-
fic and stop-and-go traffic.
Switch these functions off if they
are not required.Have the vehicle serviced regularly
to achieve optimal economy and
lifetime. Toyota recommends hav-
ing maintenance work carried out
by Toyota. Switch off the engine if stop-
ping for longer periods

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 optional
equipment 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.
Before refuelling, observe the notes
on fuel quality, see page 307.
When refuelling, insert the filler
nozzle fully into the filler neck. Lift-
ing the filler nozzle during refuelling
results in the following:
The fuel supply being cut off pre-
maturely.
Fuel vapour and fumes being
recovered less effectively.
The fuel tank is full when the filler
nozzle cuts out for the first time.
Please comply with the safety regu-
lations displayed at filling stations.1Briefly press the rear edge of
the fuel filler flap.
