2023 TOYOTA SUPRA warning light

2604-1. DRIVING TIPS
When visibility is poor due to
fog, even if it is daytime, turn the
low beam headlights on to make
your vehicle more visible to
other vehicles, etc. Drive with
caution at a low speed, using
the centerline, guardrails, tail-
lights of a preceding vehicle,
etc., as guide.When the vehicle is being blown
by crosswinds, drive at a lower
speed and grip the steering
wheel stronger than normal.
The vehicle is especially sus-
ceptible to crosswinds when
exiting a tunnel or underpass,
when driving on a bridge or
embankment, or when passing
or being passed by a truck or
other large vehicle.

During a rain storm or when
the road surface is wet, the
road surface may be slippery
and visibility may be reduced.
In this case, turn the low
beam headlights on to make
your vehicle more visible to
Mobile communication
devices in the vehicle
WARNING
Vehicle electronics and mobile
phones can influence one
another. There is radiation due to
the transmission operations of
mobile phones. There is a risk of
injury or risk of
damage to prop-
erty. If possible, in the car's inte-
rior use only mobile phones with
direct connections to an exterior
antenna in order to exclude
mutual interference and deflect
the radiation from the car's inte-
r i o r.

2624-1. DRIVING TIPS
perforated brake discs can emit
functional noises. However,
functional noises have no effect
on the performance and opera-
tional reliability of the brake.
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.
Objects in the area around
the pedals
WARNING
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 that 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
WARNING
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.
WARNING
In idle state or with the engine
switched off, safety functions, for
instance engine braking effect,
braking assistance and steering
assistance, may not be available.
There is a risk of accident. Do not
attempt to drive in idle state or
with the engine switched off.

WARNING
A damaged regular tire with low or
missing tire inflation pressure
impacts handling, such as steer-
ing and braking response. Do not
continue driving if the vehicle is
equipped with normal tires.
If a tire inflation pressure
check is required
SymbolPossible cause
Inflation was not carried
out according to specifi-
cations, e.g., when the
tire has not been suffi-
ciently inflated or in the
case of a natural steady
tire pressure loss.
If the tire inflation pressure
is too low
A yellow warning light is
illuminated in the instru-
ment cluster.
SymbolPossible cause
There is a tire inflation
pressure loss.

1 Identify the damaged tire.
Check the tire inflation pressure in
all four tires, for instance using the
tire pressure gauge of a flat tire kit.
For tires with special approval: if
the tire inflation pressure in all four
tires is correct, t he TPM may not
have been reset. In this case, per-
form the reset.
If tire damage cannot be found,
contact your Toyota dealer.
If the tire inflation pressure
is too low
A yellow warning light is
illuminated in the instru-
ment cluster.

pressure loss.

Actions in the event of a
flat tire

2945-1. MOBILITY
2Repair the flat tire, e.g., with
a flat tire kit or by changing
the wheel.
Use of sealant, for instance from
the flat tire kit, may damage the
TPM wheel electronics. Have
the electronics replaced at the
next opportunity.
The tire inflation pressure
depends on the tire's tempera-
ture.
Driving or exposure to the sun
will increase the tire's tempera-
ture, thus increasing the tire
inflation pressure.
The tire inflation pressure is
reduced when the tire tempera-
ture falls again.
These circumstances may
cause a warning when tempera-
tures fall very sharply.
Following a temperature-related
warning, the target pressures
are displayed on the Control
Display again after a short dis-
tance.
The system cannot indicate sud-
den serious tire damage caused
by external circumstances. Tires with special approval: the
system will not function correctly
if a reset was not performed, for
example a flat tire may be indi-
cated although the tire inflation
pressures are correct.
• A wheel without TPM wheel
electronics, such as an emer-
gency wheel, is mounted:
have the wheels checked, if
needed.
• Malfunction: have the system checked.
• Interference caused by sys- tems or devices with the
same radio frequency: after
leaving the area of the inter-
ference, the system automati-
cally becomes active again.
• For tires with special approval: the system was
unable to complete the reset.

mercially available additives are
suitable for the vehicle. The
vehicle manufacturer recom-
mends using coolant with the
BMW LC-18 specification. Do
not mix additives of different col-
ors. Observe the water - additive
mixture ratio of 50:50. Informa-
tion about suitable additives is
available from your Toyota
dealer.
Depending on the motorization,
there are up to two coolant res-
ervoirs in the engine compart-
ment. Check and top up the
coolant levels on a regular
basis.The coolant may be overfilled in
the coolant reservoir when the
vehicle is delivered from the fac-
tory. The normal coolant level is
achieved by operating the vehi-
cle for a longer period.
The coolant level is indicated
using the maximum mark in the
filler neck of the coolant reser-
voir.
Additional information:
For an overview, refer to page

Let the engine cool.
2 Open the hood, refer to page
299.
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.
Safety information
WARNING
With the engine hot and the cool-
ing system open, coolant can
escape and lead to scalding.
There is a risk of injury. Only open
the cooling system with the
engine cooled down.
WARNING
Additives are harmful and incor-
rect additives can damage the
engine. There is a risk of injury
and risk of damage to property.
Do not allow additives to come
into contact with skin, eyes or arti-
cles of clothing. Use suitable addi-
tives only.
