2644-1. DRIVING TIPS
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 148.
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

into the power socket inside
the vehicle.
6 With standby state switched
on or the engine running,
switch on the compressor.
Let the compressor run for max.
10 minutes to fill the tire with
sealant and achieve a tire infla-
tion pressure of approx. 2.0 bar.
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.
1 Switch 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.
4 Wrap and store the sealant
container in suitable material
to avoid dirtying the cargo
area.
1 Pull the connector out of the
power socket inside the vehi-
cle.
2 Drive 33 ft/10 m forward and
back to distribute the sealant
in the tire.

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.
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
sporty driving style, for instance
when taking curves aggres-
sively, regularly perform a
detailed measurement.
■Concept
The engine oil level is monitored
electronically while driving and
can be shown on the Control
Display.
If the engine oil level is outside
its permissible operating range,
a vehicle message is displayed.
■Functional requirements
A current measured value is
available after approx. 30 min-
utes of normal driving.
General information
Safety information
NOTICE
An engine oil level
that is too low
causes engine damage. There is
a risk of damage to property.
Immediately add engine oil.
NOTICE
Too much engine oil can damage
the engine or the catalytic con-
verter. There is a risk of damage
to property. Do not add too much
engine oil. When too much engine
oil is added, have the engine oil
level corrected by your Toyota
dealer.

■System limits
When making frequent

If the engine oil level is outside
its permissible operating range,
a vehicle message is displayed.
■General information
During the measurement, the
idle speed is increased some-
what.
■Functional requirements
• Vehicle is parked in a horizon- tal position.
• Manual transmission: gear- shift lever in idle position,
clutch and accelerator pedals

tor pedal not depressed.
• Engine is running and is at operating temperature.

mercially available additives are
suitable for the vehicle. The
vehicle manufacturer recom-
mends using coolant with the
BMW LC-18 specification. Do
not mix additives of different col-
ors. Observe the water - additive
mixture ratio of 50:50. Informa-
tion about suitable additives is
available from your Toyota
dealer.
Depending on the motorization,
there are up to two coolant res-
ervoirs in the engine compart-
ment. Check and top up the
coolant levels on a regular
basis.The coolant may be overfilled in
the coolant reservoir when the
vehicle is delivered from the fac-
tory. The normal coolant level is
achieved by operating the vehi-
cle for a longer period.
The coolant level is indicated
using the maximum mark in the
filler neck of the coolant reser-
voir.
Additional information:
For an overview, refer to page
298.
1
Let the engine cool.
2 Open the hood, refer to page
299.
3 Turn the lid of the coolant
reservoir slightly counter-
clockwise to allow any
excess pressure to dissi-
pate, then open it.
4 Open the coolant reservoir
lid.
5 The coolant level is correct
when it is just below the max-
imum mark in the filler neck.
Safety information
WARNING
With the engine hot and the cool-
ing system open, coolant can
escape and lead to scalding.
There is a risk of injury. Only open
the cooling system with the
engine cooled down.
WARNING
Additives are harmful and incor-
rect additives can damage the
engine. There is a risk of injury
and risk of damage to property.
Do not allow additives to come
into contact with skin, eyes or arti-
cles of clothing. Use suitable addi-
tives only.

The manufacturer of your vehi-
cle recommends that mainte-
nance and repair be performed
by a Toyota dealer. Records of
regular maintenance and repair
work should be retained.
Scheduled maintenance should

mary components in the vehi-
cle's emissions.Safety information
NOTICE
The socket for Onboard Diagno-
sis is an intricate component
intended to be used in conjunction
with specialized equipment to
check the vehicle’s primary emis-
sions system. Improper use of the
socket for Onboard Diagnosis, or
contact with the socket for
Onboard Diagnosis for other than
its intended purpose, can cause
vehicle malfunctions and creates
risks of personal and property
damage. Given the foregoing, the
manufacture of your vehicle
strongly recommends that access
to the socket for Onboard Diagno-
sis be limited to your Toyota
dealer or other persons that have
the specialized
training and
equipment for purposes of prop-
erly utilizing the socket for
Onboard Diagnosis.
