■General information
The estimated range available
with the remaining fuel is perma-
nently displayed in the instru-
ment cluster.
With a low remaining range, a
vehicle message is briefly dis-
played. With a dynamic driving
style, for instance taking curves
aggressively, the engine func-
tion is not always ensured.
The vehicle message appears
continuously below a range of
approx. 30 miles/50 km.

The current consumption dis- plays the current consumption
of fuel. Check whether you are
currently driving in an efficient
and environmentally friendly
manner.
■General information
The current fuel consumption is
displayed on the instrument
cluster as a bar display.

■General information
Average speed and average
consumption are calculated for
the distance traveled since the
last reset in the Onboard Com-
puter.
Periods in which the vehicle is
parked with the engine manually
stopped are not included in the
calculation of the average
speed.
NOTICE
With a driving range of less than
30 miles/50 km the engine may
no longer have sufficient fuel.
Engine functions are not ensured
anymore. There is a risk of dam-
age to property. Refuel promptly.

DRIVING TIPS
vehicle is not used at all.
 Infrequent use of the brakes.
 Aggressive, acidic, or alka-
line cleaning agents.
Corrosion buildup on the brake
discs will cause a pulsating
effect on the brakes in their
response - generally this cannot
be corrected.
When using the automatic air
conditioning, condensation
water develops and collects
underneath the vehicle.
Higher mechanical and thermal
loads during racetrack operation
lead to increased wear. This
wear is not covered by the war-
ranty. The vehicle is not
designed for use in motor sports
competition.
Have vehicle checked by your
Toyota dealer before and after
driving on a racetrack. This chapter describes all stan-
dard, country-specific and
optional features offered with
the series. It also describes fea-
tures and functions that are not
necessarily available in your
vehicle, e.g., 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 vehicle contains advanced
technologies for the reduction of
consumption and emission val-
ues.
Fuel consumption depends on a
number of different factors.
Carrying out certain measures,
such as a moderate driving style
and regular maintenance, can
influence fuel consumption and
the environmental impact.

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 142.
When approaching a red light,
take your foot off the accelerator
and let the vehicle coast to a
halt.
For going downhill take your foot

vehicle roll.
The flow of fuel is interrupted
while coasting.
Switch off the engine during lon-
ger stops, for instance at traffic
lights, railroad crossings or in
traffic congestion.
The Auto Start/Stop function of
the vehicle automatically
switches off the engine during a
stop.
If the engine is switched off and
then restarted rather than leav-
ing the engine running con-
stantly, fuel consumption and
emissions are reduced. Sav-
ings can begin within a few sec-
onds of switching off the engine.
In addition, fuel consumption is
also determined by other fac-
tors, such as driving style, road
conditions, maintenance or envi-
ronmental factors.
Functions such as seat heating
and the rear window defroster require a lot of energy and
increase fuel consumption,
especially in city and
stop-and-go traffic.
Switch off these functions if they
are not needed.
Have the vehicle maintained
regularly to achieve optimal
vehicle efficiency and service
life. Toyota recommends that
maintenance work be performed
by Toyota.

nance System, refer to page

The tire characteristics and tire
inflation pressure influence the
following:
• The service life of the tires.
• Road safety.
• Driving comfort.
• Fuel consumption.The tire inflation pressure table,
refer to page 268, contains all
tire inflation pressure specifica-
tions for the specified tire sizes
at the ambient temperature. The
tire inflation pressure values
apply to tire sizes approved by
the manufacturer of the vehicle
for the vehicle type.
To identify the correct tire infla-
tion pressure, please note the
following:
If the tire's speed code cannot
be found, then the tire inflation
pressure for the corresponding
tire size applies.
• Tire sizes of your vehicle.
• Maximum permitted driving
speed.

WARNING
A tire with too little or no tire infla-
tion pressure may heat up signifi-
cantly and sustain damage. This
will have a negative impact on
aspects of handling, such as
steering and braking response.
There is a risk of an accident.
Regularly check the tire inflation
pressure, and correct it as
needed, for instance twice a
month and before a long trip.

must not be used.
Fuels with a maximum ethanol
content of 25 %, i. e. E10 or
E25, may be used for refueling.
Ethanol should meet the follow-
ing quality standards:
US: ASTM 4806–xx
CAN: CGSB-3.511–xx
xx: comply with the current stan-
dard in each case.Toyota recommends AKI 91.
Refuel with this gasoline to
achieve the rated performance
and consumption values.
Safety information
WARNING
The use of poor-quality fuels may
result in harmful engine deposits
or damage. Additionally, problems
relating to drivability, starting and
stalling, especially under certain
environmental conditions such as
high ambient temperature and
high altitude, may occur.
If drivability prob
lems are encoun-
tered, we recommend switching
to a high quality gasoline brand
and a higher octane grade - AKI
number - for a few tank fills. To
avoid harmful engine deposits, it
is highly recommended to pur-
chase gasoline from Top Tier
retailers.
Failure to comply with these rec-
ommendations may result in the
need for unscheduled mainte-
nance.
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.
Do not press the Start/Stop button
after refueling with the wrong fuel.
Contact your Toyota dealer.
• Metallic additives , for instance
manganese or iron.
NOTICE
Incorrect fuels can damage the
fuel system and the engine. There
is a risk of damage to property. Do
not use fuels with a higher per-
centage of ethanol than recom-
mended. Do not refuel with fuels
containing methanol, 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.

Toyota recommends AKI 89.
If you use gasoline with this min-
imum AKI Rating, the engine
may produce knocking sounds
when starting at high external
temperatures. This has no effect
on the engine life.
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.
The engine oil consumption can
increase in the following situa-
tions, for example:
• Sporty driving style.
• Break-in of the engine.
• Idling of the engine.
• With use of engine oil types that are classified as not suit-
able.
Different vehicle messages
appear on the Control Display
depending on the engine oil
level. The electronic oil measurement
has two measuring principles:
• Monitoring.
• Detailed measurement.
When making frequent
short-distance trips or using a
dynamic driving style, for
instance when taking curves
aggressively, regularly perform
a detailed measurement.
■Concept
The engine oil level is monitored
electronically while driving and
can be shown on the Control
Display.
