 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:
if the radar sensors are dirty
or covered.
 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.
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. If an accident can-
not be prevented, the system
will help reduce the impact
speed.
The system 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
the detection range of the sys-
tem.
Depending on the equipment
version, the system is controlled
by the following sensors:

Camera in the area of the
interior mirror.
 Radar sensor in the front
bumper.

trians and cyclists when the
speed of the vehicle is below
approx. 53 mph/85 km/h.
The system's detection potential
is limited.
Thus, a warning might not be
issued or be issued late.
The following situations may not
be detected, for instance:
 Partially covered pedestrians.
 Pedestrians that are not
detected as such because of
the viewing angle or contour.
 Pedestrians outside of the
detection range.
 Pedestrians having a body
size less than 32 in/80 cm.
The system may not be fully
functional or may not be avail-
able in the following situations:
 In heavy fog, wet conditions,
or snowfall.
 In tight curves.
 If the driving stability control
systems are deactivated, 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:
if the radar sensors are dirty
or covered.
 Up to 10 seconds after the
start of the engine via the

 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.
 When it is dark outside.
The lane departure warning
alerts when the vehicle is about
to run off the road or exit the
lane.
This camera-based system
warns starting at a minimum
speed.
The minimum speed is coun-
try-specific and is displayed in
the menu for the Toyota Supra
Safety systems.
Warnings are issued by means
of a steering wheel vibration.

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 shown 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

Before you change lanes after
setting the turn signal, the sys-

2504-1. DRIVING TIPS
Supra Owner's Manual
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.
 Infrequent use of the brakes.
 Aggressive, acidic, or alka-
line cleaning agents.
Corrosion buildup on the brake
discs will cause a pulsating
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-relevant func-
tions, for instanc e engine braking
effect, braking force boost and
steering assistance, are restricted
or not available at all. There is a
risk of an accident. Do not drive in
idle state or with the engine
switched off.
