Having a correct driving posture is
essential for safe driving. Maintain-
ing a correct driving posture not
only helps reduce fatigue while
driving, but helps ensure that the
occupant protection devices, such
as the seat belts and airbags, will
operate correctly in a collision,
reducing the impact to the occu-
pants.
The most basic occupant protection
device is the seat belt. The airbags
are designed to supplement the
seat belts, not be used in place of
them. Wearing the seat belt cor-
rectly ensures that the occupants
are securely held in the seats and
helps prevent them from contacting
interior parts or being thrown from
the vehicle in a co llision. Therefore,
it is necessary for all occupants to
wear their seat belt. If a seat belt is
worn improperly, its effectiveness
as an occupant protection device
will be severely reduced. Pay atten-
tion to the following to ensure the
correct driving posture and use of
the seat belts.

When using a child restraint system
on the front passenger seat, make
sure that the front and side airbags
on the passenger side are deacti-
vated. Front passenger airbags can
only be deactivated with the key
switch for front passenger airbags,
see page 202.
Appropriate child restraint systems
for every age and weight class are
available from any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
Please comply with the operating
and safety instructions provided by
the child restraint system manufac-
turer when selecting, attaching and
using child restraint systems.
WA R N I N G
Child restraint systems and their parts
can get very hot when exposed to
direct sunlight. Contact with hot parts can cause burns. There is a risk of
injury. Do not expose the child
restraint system to direct sunlight. Cover the child restraint system if
necessary. It may be necessary to
allow the child restraint system to cool
down before strapping a child in. Do not leave children unsupervised in the
vehicle.
WA R N I N G
Children under 150 cm, 5 ft tall cannot
wear the seat belt correctly without
using additional child restraint sys- tems. The protective function of the
seat belts may be limited or may even
fail completely if the seat belts are worn incorrectly. If a seat belt is not
worn correctly, additional injuries can
be caused, for example in the event of an accident or when braking or car-
rying out evasive manoeuvres. There
is a risk of injury or even death. Chil-
dren under 150 cm, 5 ft tall must be secured in suitable child restraint sys-
tems.

Safety note
WA R N I N G
Active front passenger airbags can
injure a child in a child restraint sys- tem if they are deployed. There is a
risk of injury. Make sure that the front
passenger airbags are deactivated and the PASSENGER AIRBAG OFF
indicator lamp is illuminated.
WA R N I N G
Children less than 150 cm, 5 ft in height cannot wear the seat belt cor-
rectly without using additional child
restraint systems. The protective function of the seat belts may be lim-
ited or may even fail completely if the
seat belts are worn incorrectly. If a seat belt is not worn correctly, addi-
tional injuries can be caused, for
example in the event of an accident or braking and evasive manoeuvres.
There is a danger of injury or even
death. Children smaller than 150 cm,
5 ft in height must be secured in suita- ble child restraint systems.

When the ambient conditions are
dry, Launch Control permits opti-
mised acceleration on a road sur-
face that offers plenty of grip.
Use of Launch Control causes pre-
mature component wear, as the
function subjects t he vehicle to very
high stresses and loads.
Do not use Launch Control when
running in, see page 280.
When starting with Launch Control,
do not turn the steering wheel.
Launch Control is available when
the engine is at operating tempera-
ture. The engine is at operating
temperature after an uninterrupted
journey of at least 10 km, approx. 6
miles.

the lane marking is detected, the
steering wheel vibrates in accord-
ance with the steering wheel vibra-
tion setting.
If the turn indicator is switched on in
the corresponding direction before
changing lanes, no warning is
issued.
Depending on the equipment, if a
lane marking is crossed in the
speed range up to 210 km/h,
approx. 130 mph, the system may
intervene not only by vibrating but
also with a brief active steering
intervention. The steering interven-
tion helps to keep the vehicle in
lane. Steering intervention can be
felt at the steering wheel, and can
be overridden manually at any time.
With active steering intervention,
the display flashes in the instru-
ment cluster.
Depending on the equipment, if the
system executes an active steering
intervention multiple times within 3
minutes without the driver touching
the steering wheel, an acoustic
warning is emitted. A short warning
signal sounds on the second steer-
ing intervention. A longer warning
signal sounds from the third steer-
ing intervention onwards.
A vehicle message is also dis-
played.
The warning signal and vehicle
message tell the driver to pay more
attention to the lane.
For example, the warning is can-
celled in the following situations:
 Automatically after a few sec-
onds.
 On returning to the correct lane.
 If the vehicle is braking heavily.
 On indicating.
 If Vehicle Stability Control VSC
intervenes.

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.

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.
