The system is reset approximately
45 minutes after the vehicle is
stopped, for example when taking a
break during a long motorway jour-
ney.This chapter describes all standard,
country-specific and special equip-
ment available for the model series.
It may therefore describe equip-
ment and functions which are not
installed in your vehicle, for exam-
ple on account of the optional
equipment selected or the country
specification. This also applies to
safety-relevant functions and sys-

ABS prevents the wheels from lock-
ing when the brakes are applied.
Steering control is retained even in
the event of full braking, thereby
enhancing active road safety.
ABS is ready to operate each time
the engine is started.
Situations which the ABS cannot
operate sufficiently:

Supra Owner's Manual3-1. CONTROLS
In this case, even if the ABS operates,
it cannot operate sufficiently to avoid a
possible dangerous situation. The
driver is solely responsible for under-
standing their surroundings and driving
at a safe speed.
When the brake pedal is depressed
quickly, the system automatically
applies maximum braking power
assistance. By doing so, the brak-
ing distance is kept as short as pos-
sible in full braking situations. The
advantages offered by the Anti-lock
Brake System ABS can also be uti-
lised to the full.
The pressure on the brake should
be maintained for the duration of
the full-braking process.
In conjunction with Adaptive Cruise
Control, this system ensures that
the brake responds even more
quickly when braking in critical situ-
ations.The system provides support when
driving off on upward gradients.
1Hold the vehicle in place by
depressing the foot brake.
2Release the foot brake and drive
off without delay.
The vehicle is held for approxi-
mately 2 seconds after the foot
brake has been released.
Depending on the vehicle's load,
the vehicle may roll backwards a lit-
tle.
The system reduces engine power
output and applies the brakes on
individual wheels thereby helping,
within the limits imposed by the
laws of physics, to keep the vehicle
safely on course.

Supra Owner's Manual4-1. DRIVING HINTS
This situation, known as aquaplan-
ing, means that the tyre can actu-
ally lose contact completely with
the road surface and the vehicle
can neither be steered, nor the
brakes properly applied.
Please comply with the following
when driving through water:
Only drive through still water.
Only drive through water up to a
max. depth of 25 cm, 9.8 in.
Drive through water at a walking
speed of no more than 5 km/h, 3
mph.
The vehicle is equipped with the
Anti-lock Brake System ABS as
standard.
Perform full braking in situations that require it.
The vehicle remains steerable. Any
obstacles can be avoided by per-
forming steering movements as
smoothly as possible.
A pulsing of the brake pedal and
hydraulic regulating sounds indi-
cate that the Anti-lock Brake Sys-
tem ABS is regulating.
In certain braking situations, the
perforated brake discs can cause
functional noise. However, func-
tional noises have no effect on the
efficiency and operational safety of
the brakes.
In damp weather, on gritted roads
and in heavy rain, apply the brakes
lightly every few kilometres/miles. Driving through water
General
Safety note
NOTICE
Driving through excessively deep
water too fast can result in water
entering the engine compartment,
electrical system or transmission.
There is a danger of damage to prop-
erty. When driving through water, do
not exceed the maximum water depth
and speed specified above.
Safe braking
General
Objects in the range of movement
of the pedals
WARNING
Objects in the driver's footwell can
restrict the pedal travel or block a
pedal that has been pressed. There is
a danger of accidents. Stow items in
the vehicle so that they are secure
and cannot get into the driver's
footwell. Only use floor mats that are
suitable for the vehicle and can be
securely fastened to the floor. Do not
use loose floor mats, and do not place
several floor mats on top of one
another. Make sure that there is suffi-
cient space for the pedals. Ensure
that floor mats are securely reat-
tached after having been removed, for
example for cleaning.

DRIVING HINTS
Ensure that you do not obstruct
other road users when doing so.
The heat generated by braking
dries the brake discs and brake
pads and protects them against
corrosion.
This way, brake power is available
immediately, whenever it is needed.
■General
When driving on long or steep
downhill stretches, use the gear in
which the least braking is required.
Otherwise the brake system can
overheat and the braking effect is
reduced.
Engine braking effect can be addi-
tionally increased by manually shift-
ing down, even into first gear, if
applicable.
■Safety notesCorrosion of the brake discs and
contamination of the brake pads
increase in the following circum-
stances:
Low mileage.
Extended periods when the vehi-
cle is not used.
Infrequent use of the brakes.
Aggressive, acidic or alkaline
cleaning agents.
Should corrosion form on the brake
discs, the brakes will tend to
respond with a judder effect that
generally cannot be eliminated.
When the automatic air condition-
ing is in operation, condensation
develops and exits underneath the
vehicle.
The higher mechanical and thermal
loads involved in driving on racing Downhill gradients
WARNING
Even slight continuous pressure on
the brake pedal can cause overheat-
ing, brake pad wear or even brake
system failure. There is a danger of
accidents. Avoid excessive loads on
the brake.
WARNING
When idling or with the engine
switched off, safety-relevant func-
tions are restricted or no longer avail-
able, for example the braking effect of
the engine or power assistance for
the braking force and steering. There
is a danger of accidents. Do not drive
at idle speed or with the engine
switched off.

WARNING
If a warning light illuminates or
flashes, or a warning message is dis-
played, immediately stop the vehicle
in a safe place. Do not open the hood
to inspect the engine, as doing so
may lead to serious injury, such as
steam burns. If a warning message is
displayed, perform the necessary pro-
cedures according to the displayed
message or explanation in the
owner’s manual.
These warning messages indicate
that a malfunction has occurred in a
system or function of the vehicle. If
you continue to drive the vehicle, the
engine may stop suddenly, possibly
leading to an accident. Also, even if
no warning lights are illuminated or
messages are displayed, if any
abnormal sounds, smells or vibrations
are detected, or of the engine stops
suddenly, refrain from opening the
hood to inspect the engine and con-
sult an authorized Toyota retailer or
Toyota authorized repairer, or any reli-
able repairer.
WARNING
If you hear a loud noise or feel some-
thing impact the underside of the
vehicle while driving, immediately
stop the vehicle in a safe place.
After stopping the vehicle in a safe
place, check the underside of the
vehicle for any leaking brake fluid, oil
or fuel. If any fluid is leaking, stop
driving immediately and have the
vehicle inspected by an authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
Brake and fuel lines run under the
floor of the vehicle. If any of these
lines are damaged, the brakes may
fail or leaking fuel may ignite and
cause a fire.
WARNING
If the engine stalls while driving, sev-
eral warning lights will illuminate.
Depending on vehicle specifications,
the power-assisted brakes and power
steering may stop operating. In this
case the braking power will be
reduced and operation of the steering
wheel will become heavy. Although
the operation of the brakes and steer-
ing will not be totally lost, they will
require stronger than normal input to
operate. Stop the vehicle in a safe
place as soon as possible.

■Safety note
■General
In a car wash, the vehicle must be
able to roll freely.
Roll or push the vehicle, see page
145.
Some car washes require you to
get out of the vehicle. It is not possi-
ble to lock the vehicle from the out-
side in selector lever position N. If an attempt is made to lock the vehi-
cle, a signal sounds.
Ensure that the remote control is
located in the vehicle.
Switch on drive-ready state, see
page 45.
Do not rub wet headlights dry and
do not use abrasive or corrosive
cleaning agents.
Soak impurities such as insect resi-
dues with shampoo and wash off
with water.
Remove ice with a de-icer spray; do
not use an ice scraper.
After the vehicle has been washed,
briefly apply the brakes to dry them
otherwise braking effectiveness
may be temporarily reduced. The
heat generated by braking dries the
brake discs and brake pads and
protects them against corrosion.
Completely remove residues on the
windscreens to avoid affecting visi-
bility due to smearing, and to
reduce wiping noise and wiper
blade wear.
NOTICE
The vehicle can be damaged if auto-
matic washing bays or car washes
are used incorrectly. There is a dan-
ger of damage to property. Observe
the following notes:
●Textile car washes or systems
using soft brushes are preferable,
to avoid damage to the paintwork.
●Avoid washing bays or car washes
with guide rails higher than 10 cm,
4 in, to avoid damage to the body.
●Note the maximum tyre width of the
guide rail to avoid damage to tyres
and rims.
●Fold in the exterior mirrors to avoid
damaging them.
●Deactivate the wipers and the rain
sensor (if fitted) to avoid damage to
the wiper system.
