Depending on the vehicle equip-
ment and country-specific ver-
sion, the vehicle features a
variety of sensors for assessing
the traffic situation. The Auto
Start/Stop function uses this
information to adapt to various
traffic situations in a proactive
manner.
For instance, this applies to the
following situations:
 If a situation is detected in
which the stopping time is
expected to be very short, the
engine is not switched off
automatically. A message
appears on the Control Dis-
play, depending on the situa-
tion.
 If a situation is detected in
which the vehicle needs to
drive off immediately, the
engine is started automati- cally.
The function may be restricted if
the navigation data is invalid,
outdated or not available, for
example.
The engine is not automatically
switched off.
The engine is started during an
automatic engine stop.

Only objects that are detected
by the system are taken into
account.
The following situations may not
be detected, for instance:
Thus, a system reaction might
not come or might come late.
The following situations may not
be detected, for instance:
Slow moving vehicles when
you approach them at high
speed.
 Vehicles that suddenly swerve in front of you, or
sharply decelerating vehicles.
 Vehicles with an unusual rear
appearance.
 Two-wheeled vehicles ahead
of you.

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. The severity of the steering
wheel vibration can be adjusted.
The system does not provide a
warning if the turn signal is set in
the respective direction before
leaving the lane.
Depending on the equipment
version, if in the speed range up
to 155 mph/250 km/h a lane
marking is crossed, the system
may intervene with a brief active
steering intervention in addition
to vibrating. The system thus
helps keep the vehicle in the
lane.
