 In tight curves.
 If the driving stability control
systems are limited or deacti-
vated, for instance VSC OFF.
 If the field of view of the cam-
era or the windshield is dirty
or covered in the area of the
interior mirror.
 If the camera has overheated
and been temporarily
switched off due to exces-
sively high temperatures.
 Depending on the equipment
version: after improperly per-
formed work on the vehicle
paint.
 After improperly performed
work on the vehicle paint in
the area of the radar sensors.
 Up to 10 seconds after the
start of the engine via the
Start/Stop button.
 During calibration of the cam-
era immediately after vehicle
delivery.
 If there are constant blinding
effects because of oncoming
light, for instance from the sun
low in the sky.
 Depending on the equipment:
if the radar sensors are dirty
or covered.
 Depending on the equipment
version: after improperly per-
formed work on the vehicle
paint.
Attaching any objects such as stickers or film in the beam area
of the radar sensors will also
impact the function of the radar
sensors and may even cause
them to fail.
The more sensitive the warning
settings are, for example the
warning time, the more warn-
ings are displayed. Therefore,
there may also be an excess of
premature or unjustified warn-
ings and reactions.
The system can help prevent
accidents involving pedestrians
and cyclists. In the event of an
accident, the system may
reduce impact speed. The sys-
tem sounds a warning in the city
speed range before an imminent
collision and activates brakes
independently, if needed.
The system issues a warning of
a possible risk of collision with
pedestrians and cyclists at
speeds above approx. 3 mph/5
km/h.
The system reacts to pedestri-
ans and cyclists who are within

A vehicle message may be dis-
played when the system is not
fully functional.
Blind spot monitor detects vehi-
cles in the blind spot or vehicles
approaching from behind in the
adjacent lane. A warning is
issued in various gradations in
these situations. Two radar sensors in the rear
bumper monitor the area behind
and next to the vehicle when
traveling faster than a minimum
speed.
The minimum speed is coun-
try-specific and is displayed in
the menu for the Toyota Supra
Safety systems.
The system indicates whether
there are vehicles in the blind
spot, arrow 1, or approaching
from behind in the adjacent
lane, arrow
2.
The light in the exterior mirror
lights up dimmed.
Before you change lanes after
setting the turn signal, the sys-
tem issues a warning in the situ-
ations described above.
The light in the exterior mirror
flashes and the steering wheel
vibrates.

Supra Owner’s Manual_U (from Mar. ’20

perforated brake discs can emit
functional noises. However,
functional noises have no effect
on the performance and opera-
tional reliability of the brake.
When roads are wet, salted, or
in heavy rain, gently press the
brake pedal every few miles.
Ensure that this action does not
endanger other traffic.
The heat generated during brak-
ing dries brake discs and brake
pads and protects them against
corrosion.
In this way braking efficiency will
be available when you need it.
■General information
Drive long or steep downhill gra-
dients in the gear that requires
least braking effort. Otherwise,
the brakes may overheat and
reduce brake efficiency.
You can increase the engine's
braking effect by shifting down,
going all the way to first gear, if
needed.
■Safety information
Corrosion on the brake discs
and contamination on the brake
pads are increased by the fol-
lowing circumstances:
 Low mileage.
 Extended periods when the
vehicle is not used at all.
Objects in the area around
the pedals
WA R N I N G
Objects in the dri
ver's floor area
can limit the peda l distance or
block a depressed pedal. There is
a risk of an accident. Stow objects
in the vehicle such that they are
secured and cannot enter into the
driver's floor area. Use floor mats
that are suitable for the vehicle
and can be safely attached to the
floor. Do not use loose floor mats
and do not layer several floor
mats. Make sure t hat there is suf-
ficient clearance for the pedals.
Ensure that the floor mats are
securely fastened again after they
were removed, fo r instance for
cleaning.
Driving in wet conditions
Hills
WA R N I N G
Light but consis tent brake pres-
sure can lead to high tempera-
tures, brakes wearing out and
possibly even brake failure. There
is a risk of an accident. Avoid
placing excessive stress on the
brake system.
WA R N I N G
In idle state or with the engine
switched off, safety functions, for
instance engine braking effect,
braking assistance and steering
assistance, may not be available.
There is a risk of accident. Do not
attempt to drive in idle state or
with the engine switched off.
