engine overheat TOYOTA GR SUPRA 2022 Owners Manual

2564-1. 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 driver'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, for instance for
cleaning.
Driving in wet conditions
Hills
WARNING
Light but consistent 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.
