The warning light
lights up:
Emissions are deterio-
rating. Have the vehi-
cle checked as soon
as possible.
 The warning light
flashes under certain
circumstances:
This indicates that
there is excessive mis-
firing in the engine.
Reduce the vehicle
speed and have the
system checked imme-
diately; otherwise, seri-
ous engine misfiring
within a brief period
can seriously damage

ponents, in particular
the catalytic converter.

sate it by briefly accelerating.
After releasing the accelerator
pedal the system is reactivated
and controls speed inde-
pendently.
In some situations, the vehicle
cannot drive off automatically;
for example:
On steep uphill grades.
 From bumps in the road.
In these cases, step on the
accelerator pedal.
The following restrictions can
occur under unfavorable
weather or light conditions:
 Poorer vehicle recognition.
 Short-term interruptions for
vehicles that are already rec-
ognized.
Examples of unfavorable
weather or light conditions:
 Wet conditions.
 Snowfall.
 Slush.
 Fog.
 Glare.
Drive attentively, and react to
the current traffic situation. If
necessary, intervene actively,
for instance by braking, steering
or evading. The desired speed is also main-
tained downhill. The speed may
not be maintained on uphill
grades if the engine power is
insufficient.
The system cannot be activated
if the radar sensor is not aligned
correctly. This may be caused
by damage incurred, for
instance during parking.
A vehicle message is displayed
if the system fails.
Have the system checked by
your Toyota dealer.
The system may be impaired
when the detection range of the
radar sensor is partially covered
such as by the license plate
holder.
The function for detecting and
responding when approaching
stationary vehicles may be lim-
ited in the following situations:

During calibration of the cam-
era immediately after vehicle
delivery.
 If the camera is malfunction-
ing or dirty. A vehicle mes-
sage is displayed.

2605-1. DRIVING TIPS
Supra Owner's Manual
Additional weight increases fuel
consumption.
Attached parts on the vehicle
impair the aerodynamics and
increase the fuel consumption.
Open windows increase air
resistance and therefore lead to
greater fuel consumption.
Tires can affect consumption in
various ways, for instance tire
size may influence consump-
tion.
Check and, if needed, correct
the tire inflation pressure at least
twice a month and before start-
ing on a long trip.
Low tire inflation pressure
increases rolling resistance and
thus raises fuel consumption
and tire wear.Do not wait for the engine to
warm-up while the vehicle
remains stationary. Start driving
right away, but at moderate
engine speeds.
This is the quickest way of
warming the cold engine up to
operating temperature.
Driving smoothly and proactively
reduces fuel consumption.
Avoid unnecessary acceleration
and braking.
By maintaining a suitable dis-
tance to the vehicle driving
ahead of you.
Driving at low engine speeds
lowers fuel consumption and
reduces wear.
If necessary, observe the vehi-
cle's gear shift indicator, refer to
page 142.
When approaching a red light,
take your foot off the accelerator
and let the vehicle coast to a
halt.
For going downhill take your foot
off the accelerator and let the

If the engine oil level is outside
its permissible operating range,
a vehicle message is displayed. A red indicator light indi-
cates that the engine oil pres-
sure is too low.
■Functional requirements
A current measured value is
available after approx. 30 min-
utes of normal driving.
■Displaying the engine oil
level
Via Toyota Supra Command:
1 "My Vehicle"
2 "Vehicle status"
3 "Engine oil level"
The engine oil leve l is displayed.
■System limits
When making frequent
short-distance trips or using a
dynamic driving style, it may not
be possible to calculate a mea-
sured value. In this case, the
measured value for the last, suf-
ficiently long trip is displayed.
■Concept
The engine oil level is checked
when the vehicle is stationary
and displayed via a scale.
If the engine oil level is outside
its permissible operating range,
a vehicle message is displayed.
■General information
During the measurement, the
idle speed is increased some-
what.
■Functional requirements
• Vehicle is parked in a horizon- tal position.
• Selector lever in selector lever position N or P and accelera-
tor pedal not depressed.
• Engine is running and is at operating temperature.
■Performing a detailed mea-
surement
Via Toyota Supra Command:
1 "My Vehicle"
2 "Vehicle status"
3 "Engine oil level"
4 "Measure engine oil level"
5 "Start measurement"
The engine oil level is checked
and displayed via a scale.
Only add engine oil when the
message is displayed in the
instrument cluster. The quantity
to be added is indicated in the
message shown on the Control
Display.
Only add suitable types of
engine oil, refer to page 299.

Vehicles with gasoline engine
feature two cooling circuits.
Always check the coolant levels
of both coolant reservoirs and
refill as needed.
The coolant level is indicated
using the Max mark in the filler
neck of the coolant reservoir.
Depending on the engine instal-
lation, the coolant reservoir is
located on the right side or the
left side of the engine compart-
ment, refer to page 293.
1 Let the engine cool.
2 Open the hood, refer to page
294.
3 Turn the lid of the coolant
reservoir slightly counter-
clockwise to allow any
excess pressure to dissi-
pate, then open it.
4 Open the coolant reservoir
lid. 5
The coolant level is correct
when it is just below the max-
imum mark in the filler neck.
6 Close the cap.
1 Let the engine cool.
2 Open the hood, refer to page
294.
3 Turn the lid of the coolant
reservoir slightly counter-
clockwise to allow any
excess pressure to dissi-
pate, then open it.
4 Open the coolant reservoir
lid.
5 If the coolant is low, slowly
add coolant up to the speci-
fied level; do not overfill.
6 Close the cap.
7 Have the cause of the cool-
ant loss eliminated as soon
as possible.
■Disposal
Comply with the relevant envi-
ronmental protection regulations
WARNING
Additives are harmful and incor-
rect additives can damage the
engine. There is a risk of injury
and risk of damage to property.

There is an OBD socket on the
driver's side for checking the pri-
mary components in the vehi-
cle's emissions. Safety information
NOTICE
The socket for Onboard Diagno-
sis is an intricate component
intended to be used in conjunction
with specialized equipment to
check the vehicle’s primary emis-
sions system. Improper use of the
socket for Onboard Diagnosis, or
contact with the socket for
Onboard Diagnosis for other than
its intended purpose, can cause
vehicle malfunctions and creates
risks of personal and property
damage. Given the foregoing, the
manufacture of your vehicle
strongly recommends that access
to the socket for Onboard Diagno-
sis be limited to your Toyota
dealer or other persons that have
the specialized
training and
equipment for purposes of prop-
erly utilizing the socket for
Onboard Diagnosis.
