Safety information
WA R N I N G
High gross weigh t can overheat
the tires, damage them internally
and cause a sudden drop in tire
inflation pressure. Driving charac-
teristics may be negatively
impacted, reducing lane stability,
lengthening the braking distances
and changing the steering
response. There is a risk of an
accident. Pay attention to the per-
mitted load capacity of the tires
and never exceed the permitted
gross weight.

Supra Owner's Manual_U (from Jul. '20 Prod.)
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
WA R N I N G
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 ord er to exclude
mutual interference and deflect
the radiation from the car's inte-
rior.

other vehicles, etc. Increase
the distance between your
vehicle and preceding vehi-
cles and drive safely at a
lower speed than normal,
avoiding sudden accelera-
tion, braking or steering oper-
ations.
 Use the rear defroster and air
conditioning system to pre-
vent the windows from fog-
ging up.
 Hydroplaning is more likely to
occur when driving on ruts or
through large puddles.
On wet or slushy roads, a
wedge of water can form
between the tires and road sur-
face.
This phenomenon is referred to
as hydroplaning. It is character-
ized by a partial or complete
loss of contact between the tires
and the road surface, ultimately
undermining your ability to steer
and brake the vehicle.
When driving through water, fol-
low the following:
 Deactivate Auto Start/Stop
function.
 Drive through calm water only.
 Drive through water only if it is
not deeper than maximum 9.8
inches/25 cm.
 Drive through water no faster
than walking speed, up to 3
mph/5 km/h.
The vehicle is equipped with an
Antilock Braking System ABS as
a standard feature.
Perform an emergency stop in
situations that require such.
Steering is still responsive. You
can still avoid any obstacles with
a minimum of steering effort.
Pulsation of the brake pedal and
sounds from the hydraulic cir-
cuits indicate that the Antilock
Braking System ABS is in its
active mode.

NOTICE
When driving too quickly through
too deep water, water can enter
into the engine compartment, the
electrical system or the transmis-
sion. There is a r isk of damage to
property. When driving through
water, do not exc eed the maxi-
mum indicated water level and the
maximum speed for driving
through water.

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
WA R N I N G
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 t hat 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

WA R N I N G
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.
WA R N I N G
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

Winter tires are recommended
for operating on winter roads.
Although so-called all-season
M+S tires provide better winter
traction than summer tires, they
usually do not provide the same
level of performance as winter
tires.
If the maximum speed of the
vehicle is higher than the per-
missible speed for the winter
tires, then attach a label show-
ing the permissible maximum
speed in the field of view. The
label is available from your Toy-
ota dealer.
With winter tires mounted,
observe and do not exceed the
permissible maximum speed.Do not exceed the maximum tire
inflation pressure indicated on
the side wall of the tire.
Store wheels and tires in a cool,
dry and dark place.
Always protect tires against all
contact with oil, grease, and sol-
vents.
Do not leave tires in plastic
bags.
Remove dirt from wheels or
tires.
• Park the vehicle as far away
as possible from passing traf-
fic and on solid ground.
• Switch on the hazard warning system.
• Secure the vehicle against rolling away by setting the
parking brake.
• Turn the steering wheel until the front wheels are in the
straight-ahead position and
engage the steering wheel
lock.

side the immediate area in a
safe place, such as behind a
guardrail.
• If necessary, set up a warning triangle at an appropriate dis-
tance.
With the Mobility System, minor
tire damage can be sealed tem-
porarily to enable continued
travel. To accomplish this, seal-
ant is pumped into the tires,
which seals the damage from
the inside.
• Follow the instructions on using the Mobility System
found on the compressor and
sealant container.
• Use of the Mobility System may be ineffective if the tire
puncture measures approx.
1/8 inches/4 mm or more.
• Contact your Toyota dealer if the tire cannot be made driv-
able.
• Do not remove foreign bodies that have penetrated the tire.
Only remove foreign objects if
they are visibly protruding
from the tire.
• Pull the speed limit sticker off the sealant container and apply it to the steering wheel.
• The use of a sealant can damage the TPM wheel elec-
tronics. In this case, have the
electronics checked and
replaced at the next opportu-
nity.
