effectiveness as an occupant pro-
tection device.
SRS is an acronym for Supplemental
Restraint System
In the event of a collision, the seat
belts restrain the occupants in their
seats, but if the impact of the colli-
sion is especially severe, there is
danger of an occupant’s head and
chest contacting the steering
wheel, dashboard and windshield.
In this case, the SRS front airbags
and SRS knee airbags deploy
(inflate), instantly creating an air
cushion to help reduce the impact
on the occupants and restrain them
from contacting the steering wheel,
etc. with their head, chest and
knees.
The SRS front air bags and SRS
knee airbags deploy only when an
impact exceeding a certain thresh-
old is detected. In a collision, even
if the impact is severe enough to
cause the vehicle body to deform,
the SRS airbags may not deploy if
the impact of the collision is suffi-
ciently dispersed by the crash
structures of the vehicle body. If the
force of the collision does not cause
the airbags to deploy, the seatbelts
will protect the occupants.
When an airbag deploys, as it will
inflate nearly instantly, it may
impact an occupant and cause an
injury, or the loud noise emitted by
ignition or deployment may cause
temporary partial loss of hearing. Also, as an airbag and nearby parts
will be extremely hot after the
airbag deploys, touching them may
cause burns. For these reasons,
deployment of the airbags is not
entirely risk free. Therefore, in
order to reduce this risk, the
airbags are designed to only deploy
when additional reduction of the
impact applied to the occupants in
a collision is necessary.
WARNING
Wear the seatbelt correctly and sit
with the correct posture.
If you sit with your head too close to
the steering wheel, when the SRS
front airbag deploys, it may apply a
very large impact to your body. Sit in
the driver’s seat with the correct pos-
ture and keep an appropriate distance
away from the steering wheel.

When a severe impact is applied to
the front of the vehicle in a side col-
lision
When a subsequent collision
occurs after the SRS front
airbags or SRS knee airbags
have operated
When only a small impact is
applied to the front of the vehicle
in a collision
When the SRS airbag warning
light is illuminated
The airbags are not designed to be
used in place of the seat belts.The SRS side airbags and SRS
curtain shield airbags are designed
to deploy and protect the torso and
head of occupants when a severe
impact is applied to the side of the
vehicle.
In the event of a side collision, the
SRS side airbag and SRS curtain
shield airbag on that side deploys
(inflates), instantly creating an air
cushion to help reduce the impact
on the occupants and restrain them
from contacting the door window,
door, etc. with their head and torso.

for the respective load conditions
will apply, in accordance with the
vehicle's actual load condition.
Example: for a partially loaded
vehicle, the optimum tyre inflation
pressure is the one stated for a par-
tially loaded vehicle.
More information regarding wheels
and tyres can be obtained from any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
The current tire pressure of each
installed wheel can be displayed on
the control display.
To ensure that they are displayed
correctly, the tyre sizes must be
stored in the system and must have
been set, see page 290, for the
mounted tyres.
The current tyre inflation pressure
value is shown on each tyre.Tyres heat up while driving. The
tyre inflation pressure increases
with the temperature of the tyre.
Tyres have a natural, uniform loss
of tyre inflation pressure.
Inflating devices can display a pres-
sure that may be up to 0.1 bar too
low.
The tyre inflation pressure inscrip-
tions on the tyre inflation pressure
sign on the door pillar only relate to
cold tyres or tyres at the same tem-
perature as the ambient tempera-
ture.
Only check the tyre inflation pres-
sures when the tyres are cold, i.e.:
• A driving distance of max. 2 km,
1.25 miles has not been
exceeded.
• If the vehicle has not moved
again for at least 2 hours after a
journey.
Regularly check the tyre inflation
pressure of the emergency wheel in
the boot and correct the pressure if
necessary.

inflation pressures for the tyres For Australia/New Zealand
WARNING
The inflation pressures on the tyre
label are applicable only for tyres
explicitly mentioned on the label.
Inflation pressures for tyres that may
be covered by the label – by size,
speed category and load rating/load
index – but not explicitly mentioned
on the label may be different. Please
obtain adequate inflation pressures in
accordance with the tyre manufac-
turer's specifications from your tyre
dealer.

Tire chains cannot be mounted.
Snow tires should be used instead.
The system monitors the tyre infla-
tion pressure in the four fitted tyres.
The system warns if the tyre infla-
tion pressure in one or more tyres
has fallen.
Sensors in the tyre valves measure
the tyre inflation pressure and tyre
temperature.
The system detects the fitted tyres
automatically. The system shows
the preset specified pressures on
the Control Display and compares
them to the current tyre inflation
pressures.
If tyres are fitted which are not
listed on the tyre inflation pressure
labels in the vehicle, see page 278, for example tyres with special
approval, the system must be
actively reset. The current tyre
inflation pressures are then
accepted as the specified values.
To operate the system, also please
comply with the other information
and notes in the chapter Tyre infla-
tion pressure, see page 278.
The following requirements must be
met for the system, otherwise relia-
ble signalling of a loss of tyre infla-
tion pressure is not ensured:
• After each tyre or wheel change,
the system has detected the fit-
ted tyres, updated the relevant
information and, after a short
journey, shown it on the Control
Display.

■Driving with tire chains
Do not fit tire chains. Tire chains may
damage the vehicle body and sus-

WARNING
The display showing the specified
tyre inflation pressures does not
replace the tyre inflation pressure
information on the vehicle. If incorrect
data has been entered into the tyre
settings, the specified tyre inflation
pressures will also be incorrect. As a
result, reliable signalling of a loss of
tyre inflation pressure can no longer
be guaranteed. There is a danger of
injury and damage to property. Make
sure that the tyre sizes of the fitted
tyres are displayed correctly and that
they match the specifications on the
tyres and the tyre inflation pressure
information.

If you have been involved in a colli-
sion, perform the following:
1Immediately leave the vehicle
and move to a safe place in
order to avoid secondary colli-
sions. Make sure to turn the
engine switch off to help prevent
the vehicle from catching fire. If
the airbags have deployed
(inflated), the airbag related
parts will be extremely hot.
Avoid touching the parts with
your hands or any part of your
body.
2If someone has been injured,
contact emergency services and
request assistance. If someone
has no obvious external injuries,
but they may have a head injury,
keep their airway open while
moving them as little as possi-
ble. If there is danger of the
vehicle being involved in a sec-
ondary collision, move the
injured person to a safe place
while keeping them as horizon-
tal as possible.
WARNING
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 lose 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, refer to page 278. If
any tire is damaged, contact any
authorized Toyota retailer or Toyota
authorized 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.
