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 146.
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.
4 Wrap and store the sealant
container in suitable material
to avoid dirtying the cargo
area. 1

optional features offered with
the series. It also describes fea-
tures that are not necessarily

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.

Coolant consists of water and
additives.
Not all commercially available
additives are suitable for the
vehicle. Do not mix additives of
different colors. Observe the
water - additive mixing ratio of
50:50. Information about suit-
able additives is available from
your Toyota dealer. Vehicles with gasoline engine
feature two cooling circuits.
Always check the coolant levels
of both coolant reservoirs and
refill as needed.
The coolant level is indicated
using the Max mark in the filler
neck of the coolant reservoir.
Depending on the engine instal-
lation, the coolant reservoir is
located on the right side or the
left side of the engine compart-
ment, refer to page 299.

The maintenance system pro-
vides service notifications and
thereby provides support in
maintaining road safety and the
operational reliability of the vehi-
cle.
In some cases, scopes and
intervals of the maintenance
system may vary according to
the country version. Replace-
ment work, spare parts, fuels
and lubricants, and wear materi-
als are calculated separately.
Further information is available
from a Toyota dealer. Sensors and special algorithms
take into account the driving
conditions of the vehicle. CBS
uses these to calculate the need
for maintenance.
The system makes it possible to
adapt the amount of mainte-
nance corresponding to your
user profile.
Information on service notifica-
tions, refer to page 145, can be
displayed on the Control Dis-
play.
Storage periods during which
the vehicle battery was discon-
nected are not taken into
account.
If this occurs, have a Toyota
dealer update the time-depen-
dent maintenance procedures,
such as checking brake fluid
and, if necessary, changing the
engine oil and the microfil-
ter/activated-charcoal filter.

Condensation can form on the
inside of the headlight glass in
cool or humid weather. When
driving with the lights switched
on, the condensation evapo-
rates after a short time. The
headlight glass does not need to
be changed.
If despite driving with the head-
lights switched on, increasing
humidity forms, for instance
water droplets in the light, have
the headlights checked. The battery is maintenance-free.
More information regarding the
battery can be requested from
your Toyota dealer.
The manufacturer of your vehi-
cle recommends that you have
your Toyota dealer register the
vehicle battery to the vehicle
after the battery has been
replaced. Once the battery has
been registered again, all com-
fort features will be available
without restriction and any vehi-
cle messages displayed which
relate to comfort features will
disappear.
The installed battery is designed
specifically for this vehicle. If an
inappropriate battery is used,
operation of the Auto Start Stop
function may be restricted in
order to protect the battery.
Also, the battery may deterio-
rate faster than normal and the
engine may not be able to be
restarted. Contact your Toyota
dealer for details.

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.

1Check whether the battery of
the other vehicle has a volt-
age of 12 volts. The voltage
information can be found on
the battery.
2 Switch off the engine of the
assisting vehicle.
3 Switch off any electronic sys-
tems/power consumers in
both vehicles.
Before you begin, switch off all
unnecessary electronic sys-
tems/power consumers, such as
the radio, on the assisting and
receiving vehicle.
1 Open the cover of the starting
aid terminal.
2 Attach one terminal clamp of
the positive jumper cable to
the positive terminal of the
battery, or to the correspond-
ing starting aid terminal of the
vehicle providing assistance.
3 Attach the terminal clamp on
the other end of the cable to
the positive terminal of the
battery, or to the correspond- ing starting aid terminal of the
vehicle to be started.
4 Attach one terminal clamp of
the negative jumper cable to
the negative terminal of the
battery, or to the correspond-
ing engine or body ground of
assisting vehicle.
5 Attach the second terminal
clamp to the negative termi-
nal of the battery, or to the
corresponding engine or
body ground of the vehicle to
be started.
Never use spray fluids to start
the engine.
1 Start the engine of the assist-
ing vehicle and let it run for
several minutes at an
increased idle speed.
2 Start the engine of the vehicle
that is to be started in the
usual way.
If the first starting attempt is not
successful, wait a few minutes
before making anot her attempt in
order to allow the discharged bat-
tery to recharge.
3 Let both engines run for sev-
eral minutes.
4 Disconnect the jumper
cables in the reverse order.
Check the battery and recharge,
if needed.
NOTICE
In the case of b ody contact
between the two vehicles, a short
circuit can occur during
jump-starting. There is a risk of
damage to propert y. Make sure
that no body contact occurs.
