◆Using Eco drive mode
Using Eco drive mode (P. 195) makes torque generation less
aggressive than normal when stepping on the accelerator pedal,
leading to improvement in fuel economy.
Also, is displayed on the air conditioning screen, indicating
the switch to ECO HEAT/COOL mode ( P. 3 0 8 ) .
◆Air conditioning system on/off
● Turn off the air conditioning system operation switch except
when necessary to help curb fuel consumption.
In summer: When the ambient temperature is high, use the recircu -
lated air mode. This decreases the load on the air con-
ditioning system.
In winter: Avoid excess heating. Use the seat heater to minimize the need for cabin heating ( P. 316).
● By pushing , ECO HEAT/COOL mode is turned on. This
helps curb fuel consumption even with the air conditioning syst em
turned on.
◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Impr oper
tire inflation pressure can cause poor fuel economy.
Additionally, snow tires have mo re rolling friction and their use on
dry roads lead to poor fuel economy. Use tires that are appropr iate
for the season.
◆Luggage
Avoid carrying unnecessary luggage and unload excess weight in
order avoid poor fuel economy. Installing a large roof rack wil l also
reduce fuel economy.

• The vehicle is being driven at extremely high speeds
• When driving on a hill
• If the radar sensor or front camera is misaligned
● In some situations such as the following, sufficient braking fo rce may not be
obtained, preventing the system from performing properly:
• If the braking functions cannot operate to their full extent, such as when
the brake parts are extremely cold, extremely hot, or wet
• If the vehicle is not properly maintained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other sli ppery sur-
face
■ If VSC is disabled
●If VSC is disabled ( P. 297), the pre-collision brake assist and pre-collision
braking functions are also disabled.

NOTICE
■Preventing sensor malfunctions
● If the area around a sensor is subjected to an impact, equipment may not
operate properly due to a sensor malfunction. Have the vehicle inspected
at your Toyota dealer.
● When using a high-pressure washer to wash the vehicle, do not s pray
water directly on the sensors. The sensors may not function pro perly if
subjected to an impact from strong water pressure.
● When using steam to wash the vehicle, do not direct steam too c lose to
the sensors. The sensors may not function properly if subjected to steam.
■ Preventing unnecessary operation
In the following situations, turn the Parking Support Brake fun ction (for static
objects) off. The system may operate even though there is no po ssibility of
a collision.
● A chassis roller, chassis dynamo, free roller or similar equipm ent is being
used for an inspection, etc.
● The vehicle is being loaded onto a ship, truck or other transpo rt vessel
● The suspension has been lowered or tires that have a different size than
the genuine tires are equipped
● The height of the vehicle has drastically changed due to the ca rried load
(the nose tilts up or down).
● A towing eyelet is installed
● When using an automatic car wash

WARNING
■Replacing tires
Make sure that all tires are of the specified size, brand, trea d pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC and VSC systems will not function correctly if di fferent tires
are installed on the vehicle.
Contact your Toyota dealer for further information when replaci ng tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspensio n will affect
the driving assist systems, and may cause a system to malfuncti on.

WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of acciden ts.
Failure to do so may result in a loss of vehicle control and ca use death or
serious injury.
● Use tires of the specified size.
● Maintain the recommended level of air pressure.
● Do not drive in excess of 75 mph (120 km/h), regardless of the type of
snow tires being used.
● Use snow tires on all, not just some wheels.
■ Driving with tire chains
Observe the following precautions to reduce the risk of acciden ts.
Failure to do so may result in the vehicle being unable to be d riven safely,
and may cause death or serious injury.
● Do not drive in excess of the speed limit specified for the tir e chains being
used, or 30 mph (50 km/h), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden regenerative braking.
● Slow down sufficiently before entering a curve to ensure that v ehicle con-
trol is maintained.
● Do not use LDA (Lane Departure Alert with steering control) sys tem.
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from Toyota dealer s or legiti-
mate tire retailers.
This is because the removal and attachment of snow tires affect s the opera-
tion of the tire pressure warning valves and transmitters.
■ Fitting tire chains
The tire pressure warning valves and transmitters may not funct ion correctly
when tire chains are fitted.
