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.

This chapter describes all standard,
country-specific and special equip-
ment available for the model series.
It may therefore describe equip-
ment and functions which are not
installed in your vehicle, for exam-
ple on account of the special equip-
ment selected or the country
specification. This also applies to
safety-relevant functions and sys-
tems. Please comply with the rele-
vant laws and regulations when
using the corresponding functions
and systems.
The vehicle has a wide range of
technologies for reducing con-
sumption and emissions.
The fuel consumption depends on
various factors, for example driving
style, road conditions, service or
environmental factors.
A number of measures, such as a
moderate driving style and regular
maintenance, can influence fuel
consumption and reduce the bur-
den on the environment.
Extra weight increases fuel con-
sumption.
Add-on parts on the vehicle can
adversely affect its aerodynamic
performance and increase fuel con-
sumption.
Open windows increase drag and
consequently fuel consumption.
Tyres can have diff ering effects on
fuel consumption figures. The tyre
size, for example, can influence
how much fuel a vehicle uses.
Check and, if necessary, correct the
tyre inflation pressures at least
twice a month and before setting off
on a longer journey.
Insufficient tyre inflation pressure
increases rolling resistance and
consequently fuel consumption and
tyre wear.
Do not warm up the engine with the
vehicle at a stands till, but instead

set off straight away, driving at
moderate engine speeds.
This brings the cold engine up to
operating temperature as quickly as
possible.
Anticipating the road situation and
adopting a smooth driving style will
reduce fuel consumption.
Avoid accelerating and braking
unnecessarily.
Keep an appropriate distance from
the vehicle ahead.
Driving at low engine speeds
reduces fuel consumption and
wear.
Pay attention to the shift position
indicator, see page 171, in the vehi-
cle, if fitted.
When approaching a red traffic
light, take your foot off the accelera-
tor and allow the vehicle to coast to
a stop.
On downward stretc hes, take your
foot off the accelerator and allow
the vehicle to roll.
The fuel supply is interrupted in
overrun mode.
When you stop the vehicle for
longer periods, for example at traf-
fic lights, railway crossings or in
traffic jams, switch off the engine.
The Auto Start/Stop of the vehicle
shuts off the engine automatically
during a stop.
Switching the engine off and on
again reduces fuel consumption
and emissions compared with a
permanently running engine. Sav-
ings can be made just by shutting
down the engine for a few seconds.
Functions such as seat heating or
rear window heating require a great
deal of energy and increase fuel
consumption, especially in city traf-
fic and stop-and-go traffic.
Switch these functions off if they
are not required.
Have the vehicle serviced regularly
to achieve optimal economy and
lifetime. Toyota recommends hav-
ing maintenance work carried out

This chapter describes all standard,
country-specific and special equip-
ment available for the model series.
It may therefore describe equip-
ment and functions which are not
installed in your vehicle, for exam-
ple on account of the special equip-
ment selected or the country

safety-relevant functions and sys-
tems. Please comply with the rele-
vant laws and regulations when
using the corresponding functions
and systems.
Before refuelling, observe the notes
on fuel quality, see page 322.
When refuelling, insert the filler
nozzle fully into th e filler neck. Lift-
ing the filler nozzle during refuelling
results in the following:
 The fuel supply being cut off pre-
maturely.
 Fuel vapour and fumes being
recovered less effectively.
The fuel tank is full when the filler
nozzle cuts out for the first time.
For Korea: Make sure that the fuel
tank cap is closed properly after
refuelling, otherw ise the emissions
warning lamp may illuminate.
Please comply with the safety regu-
lations displayed at filling stations.
1 Briefly press the rear edge of
the fuel filler flap.

Safety notes
NOTICE
If the range drops below 50 km, 30
miles, the engine may no longer be
supplied with sufficient fuel. Engine function is no longer ensured. There
is a danger of damage to property.
Refuel in good time.
NOTICE
Fuels are poisonous and aggressive.
Overfilling the fuel tank can damage the fuel system. If fuel comes into
contact with paintwork, it can damage
them. This pollutes the environment. There is a danger of damage to prop-
erty. Avoid overfilling.

compressor is switched off.
6 Switch on the compressor with
standby state switched on or the
engine running.
Let the compressor run for approxi-
mately 10 minutes to fill the sealing
compound and achieve a tyre infla-
tion pressure of approximately 2.0
bar.
The tyre inflation pressure may rise
to approximately 5 bar during the
filling process of the sealing com-
pound. Do not switch off the com-
pressor during this step.
1 Switch off compressor.
2 Read off the tyre inflation pres-
sure as shown on the tyre pres-
sure indicator.
To be able to continue the journey,
a tyre inflation pressure of at least 2
bar must be reached.
1 Unscrew the filler hose of the
sealant container from the tyre
valve.
2 Press the red unlocking device.
3 Remove the sealant container
from the compressor.
4 Pack and store the sealant con-
tainer to avoid soiling the boot.
1 Unplug the connector from the
socket in the vehicle interior.
2 Drive forwards and backwards
by 10 m, approximately 400
inches, to distribute the sealant
in the tyre.

(TPM), see page 304.
Have the punctured tyre and the
sealant containe r of the Mobility
System replaced as soon as possi-
ble.
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 292,
