Supra Owner's Manual4-1. DRIVING HINTS
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.

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.

Supra Owner's Manual5-1. MOBILITY
In the event of a complete loss of
tyre inflation pressure, run-flat tyres
enable you to continue driving, with
certain restrictions.
The wheels are fitted with tyres
which are self-supporting to a lim-
ited degree. They may also have
special rims.
The reinforced side wall means that
the tyre keeps the vehicle mobile to
a degree even if tyre inflation pres-
sure has been lost.
Observe the notes on continuing to
drive with a flat tyre.The tyres are identified on the tyre's
side wall by RSC Runflat System
Component.
• Park the vehicle on a firm sur-
face and as far away from mov-
ing traffic as possible.
• Switch on the hazard warning
lights.
• Apply the parking brake to pre-
vent the vehicle rolling away.
• Engage the steering wheel lock
with the wheels in the
straight-ahead position.
• Have all vehicle occupants get
out of the vehicle and guide them
out of the danger area, for exam-
ple behind the crash barrier.
• Set up the warning triangle an
appropriate distance away.
Run-flat tyres

General
Safety notes
WARNING
A run-flat tyre which has low tyre infla-
tion pressure or no tyre inflation pres-
sure at all will change the vehicle's
handling characteristics, for example
there may be reduced directional sta-
bility when braking, longer braking
distances and different self-steering
characteristics. There is a danger of
accidents. Drive with care and do not
exceed a speed of 80 km/h, 50 mph.

WARNING
A blocked exhaust pipe or inadequate
ventilation can allow harmful exhaust
fumes to enter the vehicle. The
exhaust fumes contain pollutants
which are colourless and odourless.
In enclosed spaces, the exhaust
fumes can also build up outside the
vehicle. There is a danger of fatal
injury. Keep the exhaust pipe clear
and ensure sufficient ventilation.
NOTICE
The compressor can overheat if oper-
ated for too long. There is a danger of
damage to property. Do not let the

3As soon as there is an opportu-
nity, check the tyre inflation
pressure in all four tyres.
In the case of tyres with special
approval: if all four tyres are inflated to
the correct tyre inflation pressures, the
Tyre Pressure Monitor might not have
been reset. Perform a reset.
■Possible driving distance with
a deflated tyre
The possible driving distance varies
depending on the load and stresses
the vehicle is subjected to, for
example speed, road properties,
outside temperature. The driving
distance can be shorter or, if the
driving style is more careful, longer.
If the vehicle is moderately loaded
and used under favourable condi-
tions, it is possible to travel up to 80
km, 50 miles.
■Driving properties with dam-
aged tyres
On a journey with damaged tyres,
handling characteristics change
and may result in the following situ-
ations, for example:
• The vehicle losing traction more
quickly.
• Longer braking distances.
• Different self-steering character-
istics.
Adapt your driving style. Avoid
abrupt steering or driving over
obstacles, for example kerbs or
potholes.
■Final tyre failure
Vibration or loud noises during the journey may be an indication that
the tyre has finally failed.
Reduce your speed and stop the
vehicle. Parts of the tyre could
detach, which might lead to an acci-
dent.
Do not continue driving, but contact
any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
The tyre inflation pressure depends
on the temperature of the tyre.
The tyre inflation pressure
increases as the tyre temperature
increases, for example during driv-
ing or due to exposure to sunlight.
Tyre inflation pressure decreases if
the tyre temperature drops.
Through this behaviour, a warning
may be triggered if there are major
temperature drops, due to the given
warning limits.
After a temperature-related warn-
ing, the specified pressures are dis-
played again on the Control Display
after a short distance.
No warning can be given by the
system of extreme, sudden tyre fail-
ure caused by external factors.System limits

Due to its size, the faulty wheel cannot
be accommodated under the boot floor.
3Check tyre inflation pressure at
the next opportunity and correct
as necessary.
4Reset the Tyre Pressure Monitor
(TPM).
5Check the tight fit of the wheel
studs using a calibrated torque
wrench.
6Drive to the nearest any author-
ized Toyota retailer or Toyota
authorized repairer, or any relia-ble repairer to have the dam-
aged tyre replaced.
In case of a flat tyre, the emergency
wheel can be used as a replace-
ment for the defective tyre. The
emergency wheel is intended for
short-term use until the defective
wheel has been replaced.
Only fit one emergency wheel at
most.
Additionally, regularly check the
tyre inflation pressure of the emer-
gency wheel in the boot and correct
the pressure if necessary. After changing the wheel
