The warning prompts the driver
to intervene. When the brake
pedal is pressed quickly and
hard, the maximum braking
force of the vehicle is used.
If there is a risk of collision, the
system may also assist with
brake intervention.
When the vehicle is traveling at
a low speed, the vehicle may
come to a complete stop.
Manual transmission: during a
brake intervention up to a com-
plete stop, the engine may be
shut down.
The braking intervention can be
interrupted by stepping on the
accelerator pedal with sufficient
force or by actively moving the
steering wheel.The system responds to pedes-
trians and cyclists when the
speed of the vehicle is below
approx. 53 mph/85 km/h.
The system's detection potential
is limited.
Thus, a warning might not be
issued or be issued late.
The following situations may not
be detected, for instance:

Partially covered pedestrians.
 Pedestrians that are not
detected as such because of
the viewing angle or contour.
 Pedestrians outside of the
detection range.
 Pedestrians having a body
size less than 32 in/80 cm.

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 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 273, 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.

Safety information
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.

The current tire inflation pres-
sure values and the intended
tire inflation pressure values for
the mounted tires can be dis-
played on the Control Display.
To ensure that they are dis-
played correctly, the tire sizes
must be stored in the system
and must have been set, refer to
page 287, for the mounted tires.
The current tire inflation pres-
sure value is located on each
tire.
The reference tire inflation pres-
sure value is located in the
lower area of the Control Dis-
play.
Tires heat up while driving. The
tire inflation pressure increases
with the tire temperature.
Tires have a natural, consistent
loss of tire inflation pressure.
The displays of inflation devices
may under-read by up to 0.1
bar/2 psi.The tire inflation pressure speci-
fications in the tire inflation pres-
sure table only relate to cold
tires or tires at the same tem-
perature as the ambient tem-
perature.
Only check the tire inflation
pressure levels when the tires
are cold, i.e.:
• Driving range of max. 1.25
miles/2 km has not been
exceeded.
• If the vehicle has not moved again for at least 2 hours after
a trip.
Check the tire inflation pressure
of the emergency wheel in the
cargo area regularly, and correct
it as needed.
1 Determine, refer to page 270,
the intended tire inflation
pressure levels for the
mounted tires.
2 Check the tire inflation pres-
sure in all four tires, using a
pressure gauge, for example.
3 Correct the tire inflation pres-
sure if the actual tire inflation
pressure deviates from spec-
ified tire inflation pressure.
4 Check whether all valve caps
are screwed onto the tire
valves.

occur with low-profile tires,
which provide less cushioning
between the wheel and the
road. Be careful to avoid road
hazards and reduce your speed,
especially if your vehicle is
equipped with low-profile tires.
Indications of tire damage or
other vehicle malfunctions:
• Unusual vibrations.
• Unusual tire or running noises.
• Unusual handling such as a strong tendency to pull to the
left or right.
• Uneven wear pattern, e.g., increased wear in the area of
the tire shoulder.
Damage can be caused by the
following situations, for instance:
• Driving over curbs.
• Road damage.
• Tire inflation pressure too low.
• Vehicle overloading.
• Incorrect tire storage. Have mounting and wheel bal-
ancing carried out by your Toy-
ota dealer.
The following properties are rec-
ommended and approved by the
manufacturer of the vehicle for
the approved wheels and tires
per vehicle type and special
equipment:
• Wheel and tire combinations.
• Rim designs.
• Tire sizes.
• Tire brands.
You can ask your Toyota dealer
about the approved wheels and
tires for the vehicle and the spe-
cial equipment.
Safety information
WARNING
Damaged tires can lose tire infla-
tion pressure, which can lead to
loss of vehicle control. There is a
risk of an accident. If tire damage
is suspected while driving, imme-
diately reduce speed and stop.
Have wheels and tires checked.
For this purpose, drive carefully to
the nearest your Toyota dealer.
Have vehicle towed or trans-
ported as needed. Do not repair
damaged tires, but have them
replaced.
WARNING
Tires can become damaged by
driving over obstacles, e.g., curbs
or road damage, at high speed.
Larger wheels have a smaller tire
crosssection. The smaller the tire
cross-section, the
higher the risk
of tire damage. There is a danger
of accidents and property dam-
age. If possible, avoid driving over
objects or road conditions that
may damage tires, or drive over
them slowly and carefully.

For each tire size, the manufac-
turer of the vehicle recommends
certain tire brands. The tire
brands can be identified by a
star on the tire sidewall.
Tire traction is not optimal due to
manufacturing circumstances
when tires are brand-new; they
achieve their full traction poten-
tial after a break-in time.
Drive conservatively for the first
200 miles/300 km.
Safety information
WARNING
Wheels and tires which are not
suitable for your
vehicle can dam-
age parts of the vehicle, for
instance due to contact with the
body due to tolerances despite
the same official size rating.
There is a risk of an accident. The
manufacturer of your vehicle
strongly suggests that you use
wheels and tires that have been
recommended by the vehicle
manufacturer for your vehicle
type.
WARNING
Mounted steel wheels can cause
technical problem s, for instance
unexpected loosening of the lug
bolts and damage to the brake
discs. There is a risk of accident.
Do not mount steel wheels.
WARNING
Incorrect wheel/tire combinations
will have a negative impact on the
vehicle's handling and on the
function of a variety of systems,
such as the Anti-lock Brake Sys-
tem or Vehicle S tability Control
System. There is a risk of an acci-
dent. To maintain good handling
and vehicle response, use only
tires with a single tread configura-
tion from a single manufacturer.
The manufacturer of the vehicle
recommends that you use wheels
and tires that have been recom-
mended by the vehicle manufac-
turer for your vehicle type.
Following tire damage, have the
original wheel/tire combination
remounted on the vehicle as soon
as possible.
Recommended tire brands
New tires
Retreaded tires
WARNING
Retreaded tires can have different
tire casing structures. With
advanced age the service life can
be limited. There is a risk of acci-
dent. The manufacturer of the
vehicle does not recommend the
use of retreaded tires.

Winter tires are recommended
for operating on winter roads.
Winter tires can be identified by
the symbol with mountain and
snowflake, as well as the M+S
marking on the tire sidewall.
So-called all-season tires with
M+S designation, but without
symbol with mountain and
snowflake, have better winter
characteristics than summer
tires but generally do not
achieve the performance of win-
ter tires.
If the maximum speed of the
vehicle is higher than the per-
missible speed for the winter
tires, then attach a label show-
ing the permissible maximum
speed in the field of view. The
label is available from your Toy-
ota dealer.
With winter tires mounted, observe and do not exceed the
permissible maximum speed.
Do not exceed the maximum tire
inflation pressure indicated on
the side wall of the tire.
Store wheels and tires in a cool,
dry and dark place.
Always protect tires against all
contact with oil, grease, and sol-
vents.
Do not leave tires in plastic
bags.
Remove dirt from wheels or
tires.

pressure values.
If tires are being used that are
not specified on the tire inflation
pressure details on the vehicle,
refer to page 270, such as tires
with special approval, the sys-
tem needs to be actively reset.
The system will then take over
the actual tire inflation pressures
as the target pressures.
When operating the system,
also note the additional informa-
tion found in the Tire inflation
pressure, refer to page 270.
The following conditions must
be met for the system; other-
wise, reliable flagging of a loss
of tire inflation pressure is not
assured:
• After each tire or wheel change, the system detects and updates the mounted
tires and displays them after a
short trip on the Control Dis-
p l a y.
Enter the inform
ation about the
mounted tires in th e tire settings
when the system does not automat-
ically detect the tires.
• TPM does not activate until
after driving for a few minutes:
• After a tire or wheel replacement.
• Reset, for tires without special approval.
• After changing the tire setting.
• For tires with special approval:
• After a tire or wheel replacement, a reset was perfo rmed with the
correct tire inflation pressure.
• After the tire inflation pressure was adjusted to a new value, a
reset was p erformed.
• Wheels with TPM wheel elec-
tronics.
The information about the
mounted tires can be entered in
the tire settings if the system
does not automatically detect
the tires.
The tire sizes of the mounted
tires can be gathered from the
tire inflation pressure details on
the vehicle, refer to page 270, or
directly on the tires.
Safety information
WARNING
The display of the target pres-
sures is not a sub
stitute for the
tire inflation pressure details on
the vehicle. Incorrect entries in
the tire settings can lead to incor-
rect target tire inflation pressure
values. In this case, it cannot be
guaranteed that the notification of
a loss of tire inflation pressure will
be reliable. There is a risk of injury
and risk of damage to property.
Ensure that the tire sizes of the
mounted tires are displayed cor-
rectly and match the details on the
tires and on the vehicle.
