Additional weight increases fuel
consumption.
Attached parts on the vehicle
impair the aerodynamics and
increase the fuel consumption.
Open windows increase air
resistance and therefore lead to
greater fuel consumption.
Tires can affect consumption in
various ways, for instance tire
size may influence consump-
tion.
Check and, if needed, correct
the tire inflation pressure at least
twice a month and before start-
ing on a long trip.
Low tire inflation pressure
increases rolling resistance and
thus raises fuel consumption
and tire wear.Do not wait for the engine to
warm-up while the vehicle
remains stationary. Start driving
right away, but at moderate
engine speeds.
This is the quickest way of
warming the cold engine up to
operating temperature.
Driving smoothly and proactively
reduces fuel consumption.
Avoid unnecessary acceleration
and braking.
By maintaining a suitable dis-
tance to the vehicle driving
ahead of you.
Driving at low engine speeds
lowers fuel consumption and
reduces wear.
If necessary, observe the vehi-
cle's gear shift indicator, refer to
page 140.
When approaching a red light,
take your foot off the accelerator
and let the vehicle coast to a
halt.

While the tire is being filled with
sealant, the tire inflation pres-
sure may sporadically reach
approx. 5 bar. Do not switch off
the compressor at this point.
1Switch off the compressor.
2 Read the tire inflation pres-
sure on the tire pressure
gauge.
To continue the trip, a tire infla-
tion pressure of at least 2 bar
must be reached.
1 Unscrew the filling hose of
the sealant container from
the tire valve.
2 Press the red unlocking
device.
3 Remove the sealant con-
tainer from the compressor.

Refuel with this gasoline to achieve the rated performance
and consumption values.
Toyota recommends AKI 89.
If you use gasoline with this min-

may produce knocking sounds
when starting at high external
temperatures. This has no effect
on the engine life.
This chapter describes all stan-
dard, country-specific and
optional features offered with
the series. It also describes fea-
tures that are not necessarily
available in your vehicle, for
instance, due to the selected
options or country versions. This
also applies to safety-related
functions and systems. When
using these functions and sys-
tems, the applicable laws and
regulations must be observed.
The engine oil consumption is
dependent on your driving style
and driving conditions.
Therefore, regularly check the
engine oil level after refueling by
taking a detailed measurement.
NOTICE
Even small quantities of the
wrong fuel or wrong fuel additives
can damage the fuel system and
engine. Furthermore, the catalytic
converter is permanently dam-
aged. There is a risk of damage to
property. Do not refuel or add the
following in the case of gasoline
engines:
• Leaded gasoline.
• Metallic additives, for instance
manganese or iron.
Do not press the Start/Stop button
after refueling with the wrong fuel.
Contact your Toyota dealer.
NOTICE
Incorrect fuels can damage the
fuel system and the engine. There

not use fuels with a higher per-
centage of ethanol than recom-
mended. Do not refuel with fuels
containing metha nol, e.g. M5 to
M100.
NOTICE
Fuel that does not comply with the
minimum quality can compromise
engine function or cause engine
damage. There is a risk of dam-
age to property . Do not fill with
fuel that does not comply with the
minimum quality.

In some cases, scopes and
intervals of the maintenance
system may vary according to
the country version. Replace-

and lubricants, and wear materi-

Further information is available
from a Toyota dealer.Sensors and special algorithms

Storage periods during which
the vehicle battery was discon-

If you have been involved in a
collision, perform the following:
1Immediately leave the vehi-
cle and move to a safe place
in order to avoid secondary
collisions. Make sure to turn
the engine switch off to help
prevent the vehicle from
catching fire. If the airbags
have deployed (inflated), the
WA R N I N G
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 leak-
ing, stop driving immediately and
have the vehicle inspected by an
authorized Toyota retailer or Toy-
ota 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.
WA R N I N G
During normal driv ing, do not turn
off the engine. Turning the engine
off while driving will not cause loss
of steering or braking control, but
the power assist to these systems
will be lost. This will make it more
difficult to steer and brake, so you
should pull over and stop the
vehicle as soon as it is safe to do
so.
WA R N I N G
While driving, if a tire has been
punctured 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 steer-
ing operations as doing so may
cause you to lose control of the
vehicle. Gradually reduce the
vehicle speed and stop the vehi-
cle in a safe place.
