Before starting the engine, per-
form the necessary routine vehi-
cle checks. It is the owner’s
responsibility to perform routine
vehicle checks and any legally
necessary yearly inspections,
according to any local laws and
regulations. For details about
inspection procedures, refer to
the Service Book (Maintenance
Guide).
Entering
Before driving
Vehicle inspection
WA R N I N G
Do not leave flammable objects in
the vehicle.
If a fuel can, combustible car care
products, spray cans, etc. are left
in the vehicle, there is a danger
that they may catch fire and
explode. Also, when the vehicle is
parked with the doors and win-
dows completely closed, do not
leave containers of carbonated
beverages in the vehicle, as the
temperature inside the vehicle
can increase to over 122°F,
depending on the location.
WA R N I N G
Make sure to securely stow all
luggage.
In the case of sudden braking or a
collision, unsecured objects may
fly about and strike the occupants,
possibly causing injury. Make sure
to stow luggage securely in the
luggage compartment.
WA R N I N G
Do not leave objects on the
driver

There are blind spots around
the vehicle which cannot be
seen from the driver’s seat.
Make sure to check the area
WA R N I N G
If an object gets s tuck behind the
brake pedal, braking may be
impossible and the accelerator
pedal may not return after being
depressed, leading to an
extremely dangerous situation.
WA R N I N G
Make sure that the floor mats are
securely installed.
Make sure to only use genuine
Toyota floor mats which are
designed for th is model and
secure them in place using the
provided fasteners. When the
floor mats have been removed,
such as when cleaning the vehi-
cle, make sure to s ecurely install
the floor mats using the fasteners
before driving the vehicle.
If a floor mat which cannot be
installed securely , due to a dam-
aged fastener, etc., is used, it may
shift while drivi ng and cover the
accelerator pedal, possibly
depressing it and causing an acci-
dent.
Additionally, never install two or
more floor mats on top of each
other. Not only will additional floor
mats interfere with normal opera-
tion of the pedals , but there is a
danger that a mat may curl behind
the brake pedal and prevent it
from being depressed.
WA R N I N G
Be careful not to inhale exhaust
gases.
The exhaust includes colorless,
odorless carbon monoxide (CO).
Carbon monoxide (CO) can be
inhaled without noticing and in the
worst cases, can cause death.
Make sure to not allow the engine
to idle in a closed off garage or
other location with poor ventila-
tion.
If there is a hole or crack in the
exhaust system, caused by corro-
sion, etc., exha ust gasses may
enter the vehicle while driving. If
you smell exhaust gasses in the
vehicle, completely open all of the
windows and have the vehicle
inspected by Toyota dealer.
Confirm safety of sur-
roundings

The tire inflation pressure speci-
fications can be found in the tire
inflation pressure table in the
printed Owner's Manual.
With Tire Pressure Monitor

The corrected tire inflation pres-
sures are applied automatically.
Make sure that the correct tire
settings have been made.
With tires that cannot be found
in the tire pressure values on
the Control Display, reset the
Tire Pressure Monitor TPM.
Regularly check the tire inflation
pressure and correct it as
needed:
• At least twice a month.
• Before embarking on an extended trip. The friction during hard braking
may produce brake dust and
make the rims dirty. Brake dust
can be removed by cleaning the
rims. Toyota recommends using
vehicle care and cleaning prod-
ucts from Toyota.
Depending on the previous dis-
plays, the status display
appears when the engine is run-

and controls speed inde-
pendently.
In some situations, the vehicle
cannot drive off automatically;
for example:
On steep uphill grades.
 From bumps in the road.
In these cases, step on the
accelerator pedal.
The following restrictions can
occur under unfavorable
weather or light conditions:
 Poorer vehicle recognition.
 Short-term interruptions for
vehicles that are already rec-
ognized.
Examples of unfavorable
weather or light conditions:
 Wet conditions.
 Snowfall.
 Slush.
 Fog.
 Glare.
Drive attentively, and react to
the current traffic situation. If
necessary, intervene actively,
for instance by braking, steering
or evading. The desired speed is also main-
tained downhill. The speed may
not be maintained on uphill
grades if the engine power is
insufficient.
The system cannot be activated
if the radar sensor is not aligned
correctly. This may be caused
by damage incurred, for
instance during parking.
A vehicle message is displayed
if the system fails.
Have the system checked by
your Toyota dealer.
The system may be impaired
when the detection range of the
radar sensor is partially covered
such as by the license plate
holder.
The function for detecting and
responding when approaching
stationary vehicles may be lim-
ited in the following situations:

During calibration of the cam-
era immediately after vehicle
delivery.
 If the camera is malfunction-
ing or dirty. A vehicle mes-
sage is displayed.
