Safety notes
WA R N I N G
A blocked exhaust pipe or inadequate
ventilation can allow harmful exhaust fumes to enter the vehicle. The
exhaust fumes contain pollutants
which are colourless and odourless. In enclosed spaces, exhaust fumes
can also build up outside the vehicle.
There is a danger of fatal injury. Keep
the exhaust pipe clear and ensure sufficient ventilation.
WA R N I N G
An unsecured vehicle can start mov-ing and rolling away. There is a risk of
accident. 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.
NOTICE
Repeated start attempts or starting
several times in quick succession
means that fuel is not burned or is inadequately burned. The catalytic
converter can overheat. There is a
risk of material damage. Avoid repeat-
edly starting in quick succession.

CONTROLS
The system reacts to pedestrians
and cyclists if your own speed is
below approx. 85 km/h, 53 mph.
The detection ability of the system
is limited.
As a result, the system may fail to
give warnings or may give warnings
late.
It is possible that the following are
not detected, for example:
 Partially concealed pedestrians.
 Pedestrians who are not
detected as such, because of the
viewing angle or outline.
 Pedestrians outside the detec-
tion range.
 Pedestrians less than approxi-
mately 80 cm, 32 in tall.
The system may have limited func-
tionality in some situations, for
example:
 In thick fog, wet conditions or
snow.
 On sharp bends.
 If vehicle stability control sys-
tems are deactivated, for exam-
ple VSC OFF.
 If the field of view of the camera
or the windscreen in front of the
rear-view mirror is soiled or cov-
ered.
 If the camera has overheated
due to excessively high tempera-
tures and has been temporarily
deactivated.
 Depending on the equipment
version: if the radar sensors are
soiled or covered.
 Depending on the vehicle's
equipment: after work performed
incorrectly on the vehicle paint-
work.
 Up to 10 seconds after starting
the engine using the start/stop
button.
 During the camera calibration
process immediately after vehi-
cle delivery.
 If there is sustained glare due to
oncoming light, for example if the
sun is low in the sky.
 In the dark.

Safety note
WA R N I N G
The system may not re spond at all, or may respond too late, incorrectly or
without justification due to limits of the
system. There is a danger of acci-
dents or damage to property.
Observe the information on the sys-
tem limits and intervene actively if
necessary.

4-1. DRIVING HINTS
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.
