be operated when drive-ready state
is switched on.
1Depress the brake pedal.
2Press the start/stop button.
The starting process is activated
automatically for a short time and
stops as soon as the engine starts.
Most of the indicator and warning
lamps in the instrument cluster are
illuminated for different lengths of
time.
Depending on the engine version,
full drive power may only be availa-
ble approx. 30 seconds after start-
ing the engine. In this case, the
vehicle will not accelerate in the
usual way.
When drive-ready state is switched
on, the revolution counter shows
the current engine speed. Safety notes
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.
WARNING
An unsecured vehicle can start mov-
ing and rolling away. There is a dan-
ger of accidents. Before leaving the
vehicle, secure it to prevent it from
rolling away.
Observe the following to ensure that
the vehicle is secured against rolling
away:
• Apply the parking brake.
• Turn the front wheels towards the
kerb on upward or downward gradi-
ents.
• Additionally secure the vehicle on
upward or downward gradients, for
example with a chock.
NOTICE
Repeated start attempts or starting
several times in quick succession
means that fuel is not burned or is
inadequately burned. The catalytic
converter can overheat. There is a
danger of damage to property. Avoid
repeatedly starting in quick succes-
sion.

Two-wheeled vehicles ahead.
At speeds over approx. 250 km/h,
155 mph, the system is temporarily
disabled. As soon as the speed
drops back below this value, the
system responds once again
according to its settings.
The system may have limited func-
tionality in the following situations,
for example:
In thick fog, wet conditions or
snow.
On sharp bends.
When Driving Stability Control
Systems are limited or deacti-
vated, for example VSC OFF.
If the field of view of the camera
or the windscreen in front of the
rear-view mirror is soiled or cov-
ered.
If the camera has overheated
due to excessively high tempera-
tures and has been temporarily
deactivated.
Depending on the equipment
version: if the radar sensors are
soiled or covered.
Up to 10 seconds after starting
the engine using the start/stop
button.
During the camera calibration process immediately after vehi-
cle delivery.
When there is sustained glare
due to oncoming light, for exam-
ple the sun is low in the sky.
The greater the sensitivity of the
warning settings, for example warn-
ing time, the more warnings will be
displayed. As a result, there may be
an increased number of premature
or unjustified warnings and reac-
tions.
The system can help to avoid acci-
dents with pedestrians and cyclists.
If an accident cannot be avoided,
the system helps to reduce the col-
lision speed.
The system warns of the possible
risk of collision in the urban speed
range and brakes automatically, as
necessary.
At speeds above approx. 5 km/h, 3
mph, the system warns of the pos-
sible risk of collision with pedestri-
ans and cyclists.

into account if they are located Upper speed limit

Supra Owner's Manual3-1. CONTROLS
Braking can be discontinued either
by depressing the accelerator pedal
or by actively moving the steering
wheel.
The detection of objects may be
limited. Take into account the
detection range limits and the func-
tional limitations.
The system reacts to pedestrians
and cyclists if your own speed is
below approx. 85 km/h, 53 mph.
The detection ability of the system
is limited.
As a result, the system may fail to
give warnings or may give warnings
late.
It is possible that the following are
not detected, for example:
Partially concealed pedestrians.
Pedestrians who are not detected as such, because of the
viewing angle or outline.
Pedestrians outside the detec-
tion range.
Pedestrians less than approxi-
mately 80 cm, 32 in tall.
The system may have limited func-
tionality in some situations, for
example:
In thick fog, wet conditions or
snow.
On sharp bends.
If vehicle stability control sys-
tems are deactivated, for exam-
ple VSC OFF.
If the field of view of the camera

WARNING
The system may not respond at all, or
may respond too late, incorrectly or

necessary.

The system may have limited func-
tionality in the following situations,
for example:
In thick fog, wet conditions or
snow.
When there are missing, worn,
poorly visible, merging/separat-
ing or ambiguous lane markings;
for example, in areas where
there are roadworks.
If lane markings are covered by
snow, ice, dirt or water.
On sharp bends or narrow roads.
If lane markings are not white.
If lane markings are obscured by
objects.
If the vehicle is too close to the
vehicle ahead.
When there is sustained glare
due to oncoming light, for exam-
ple the sun is low in the sky.
If the field of view of the camera or the windscreen in front of the
rear-view mirror is soiled or cov-

A vehicle message may be dis-
played in the event of limited func-
tionality.
The Blind spot monitor detects
vehicles in the blind spot, or if vehi-
cles are approaching from behind
in the adjacent lane. A warning is
issued in various gradations in
these situations. System limits

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.
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.
