Tire Pressure Monitor TPM
The indicator light lights
up: the Tire Pressure
Monitor reports a low
tire inflation pressure or
a flat tire. Follow the
information in the vehi-
cle message.
The indicator light
flashes and then con-
tinuously lights up: no
flat tire or loss of tire
inflation pressure can
be detected.
 Interference caused
by systems or
devices with the
same radio fre-
quency: after leaving
the area of the inter-
ference, the system
automatically
becomes active
again.
 A wheel without TPM
wheel electronics is
mounted: have it
checked by your Toy-
ota dealer as needed.
 Malfunction: have the
system checked by
your Toyota dealer.

Emissions
 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
emission control com-
ponents, in particular
the catalyti c converter.

Even at temper atures above

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.

2645-1. DRIVING TIPS
Supra Owner’s Manual_U (from Mar. ’20
Prod.)
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 146.
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.
A current measured value is

utes of normal driving.

When making frequent
short-distance trips or using a
dynamic driving style, it may not
be possible to calculate a mea-

measured value for the last, suf-
ficiently long trip is displayed. The engine oil level is checked
when the vehicle is stationary
and displayed via a scale.

its permissible operating range,
a vehicle message is displayed.

Condensation can form on the
inside of the headlight glass in
cool or humid weather. When
driving with the lights switched
on, the condensation evapo-
rates after a short time. The
headlight glass does not need to
be changed.
If despite driving with the head-
lights switched on, increasing
humidity forms, for instance
water droplets in the light, have
the headlights checked. The battery is maintenance-free.
More information regarding the
battery can be requested from
your Toyota dealer.
The manufacturer of your vehi-
cle recommends that you have
your Toyota dealer register the
vehicle battery to the vehicle
after the battery has been
replaced. Once the battery has
been registered again, all com-
fort features will be available
without restriction and any vehi-
cle messages displayed which
relate to comfort features will
disappear.
The installed battery is designed
specifically for this vehicle. If an
inappropriate battery is used,
operation of the Auto Start Stop
function may be restricted in
order to protect the battery.
Also, the battery may deterio-
rate faster than normal and the
engine may not be able to be
restarted. Contact your Toyota
dealer for details.
