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:
 When entering a curve at an
excessively high rate of speed
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 doi ng 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 Dynamic radar
cruise control, th is system ensures
that the brake responds even more
quickly when braking in critical situ-
ations.

The desired speed is also main-
tained when drivi ng downhill. The
vehicle may drive slower than the
desired speed on uphill gradients if
there is not enough engine power.
*: if equipped
This system allows you to set a
desired speed and a desired dis-
tance from the vehicle in front,
using the buttons on the steering
wheel.
When the road ahead is clear, the
system maintains the desired
speed by braking or accelerating
the vehicle automatically, as
required.
If there is a vehicle driving in front,
the system adapts your own vehicle
speed in order to maintain the set
distance from the vehicle ahead.
The speed is adapted as far as the
given situation allows.
Depending on the vehicle settings,
the characteristics of the Cruise
Control may change.
The distance can be set in several
stages, and is dependent on the
individual speed for reasons of
safety.
If the vehicle ahead brakes to a
standstill and sets off again shortly
afterwards, the system can recog-
nise this within the bounds of what
is possible in the given conditions.
The symbol is displayed
when the set desired speed
has been reached.

Safety notes
WA R N I N G
The system does not relieve you of
your personal responsibility to assess
the traffic situation correctly. Due to system limitations, it cannot respond
independently and appropriately in all
traffic conditions. There is a danger of accidents. Adapt your driving style to
the traffic conditions. Observe the
traffic situation and intervene actively if the situation warrants it.
WA R N I N G
An unsecured vehicle can start mov-
ing and rolling away. There is a dan- ger of accidents. Before leaving the
vehicle, secure it to prevent it from
rolling away.
Observe the following to ensure that
the vehicle is secured against rolling away:
●Apply the parking brake.
●Turn the front wheels towards the
kerb on upward or downward gradi- ents.
●Additionally secure the vehicle on upward or downward gradients, for
example with a chock.

2463-1. CONTROLS
resume control of the vehicle's
speed.
The vehicle cannot drive off auto-
matically in some situations, for
example:
 On steep upward gradients.
 Before bumps or rises in the
road.
In such cases, de press the acceler-
ator pedal.
The following restrictions may apply
if the weather or lighting conditions
are unfavourable:
 Impaired detection of vehicles.
 Brief interruptions when vehicles
have already been detected.
Examples of unfavourable weather
or lighting conditions:
 Wet roads.
 Snowfall.
 Slush.
 Fog.
 Oncoming light.
Pay attention when driving and
respond to the prev ailing traffic con-
ditions. If necessary, intervene
actively, for example by braking,
steering or taking evasive action.
The desired speed is also main-
tained when driving downhill. The
vehicle may drive slower than the
desired speed on uphill gradients if
there is not enough engine power.
*: if equipped
When the systems in the vehicle
(Speed Limit Info, for example)
detect a change in the speed limit
on the route, it is possible to adopt
this new speed lim it value for the
following systems:
 Manual Speed Limiter.
 Cruise Control.
 Dynamic radar cruise control
with full-speed range.
The speed value is proposed as a
new desired speed for adopting.
The relevant system must be acti-
vated for the speed value to be
adopted.

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 notes
Corrosion 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.
During braking, corroded brake
discs may cause brake judder
which usually 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
tracks lead to increased wear. This
wear is not covered by the war-
ranty. The vehicle is not conceived
for use in motor sports competi-
tions.
Before and after driving on a racing
track, have the vehicle checked at
any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
Downhill gradients
WA R N I N G
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.
WA R N I N G
When idling or with the engine switched off, safety-relevant func-
tions, for example engine braking
effect or steering and braking force assistance, are either restricted or not
available at all. There is a risk of acci-
dent. Do not drive at idle speed or with the engine switched off.

WA R N I N G
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.
WA R N I N G
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.
WA R N I N G
While driving, if a tire has been punc-
tured or has ruptured, firmly grip the
steering wheel, gradually reduce the vehicle speed and stop the vehicle in
a safe place. Avoid sudden braking
and steering operations as doing so may cause you to lo se control of the
vehicle. Gradually reduce the vehicle
speed and stop the vehicle in a safe
place.
●Vehicles equipped with run-flat tires
As the sidewalls of run-flat tires are
especially stiff, it may be difficult to
feel when a tire is punctured or if the tire pressure has decreased sud-
denly. It may also be difficult to vis-
ually tell that a tire is flat or the inflation pressure is low.
If the tire pressure warning indicator illuminates, while avoiding sudden
braking or steering operations,
decelerate to 80 km /h or less, care- fully stop the vehicle in a safe place
and check the condition of each tire.
For details on how to check the condi- tion of the tires, see page 292. If any
tire is damaged, contact any author-
ized Toyota retailer or Toyota author- ized repairer, or any reliable repairer
for assistance.
The tire pressure warning indicator
may not illuminate if the inflation pres-
sure of a tire drops rapidly, such as when a tire has burst.
