◆Using Eco drive mode
Using Eco drive mode (→P. 181) 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. 260).
◆Air conditioning system on/off
● Turn off the air conditioning sy stem operation switch except
when necessary to help curb fuel consumption.
In summer: When the ambient temper ature is high, use the recircu-
lated air mode. This decreas es 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. 268).
● By pushing , ECO HEAT/COOL mode is turned on. This
helps curb fuel consumption even with the air conditioning system
turned on.
◆Checking tire inflation pressure
Make sure to check the tire infl ation pressure frequently. Improper
tire inflation pressure can cause poor fuel economy.
Additionally, snow tire s have more rolling friction and their use on
dry roads lead to poor fuel econom y. Use tires that are appropriate
for the season.
◆Luggage
Avoid carrying unnecessary luggage and unload excess weight in
order avoid poor fuel ec onomy. Installing a large roof rack will also
reduce fuel economy.

Conditions in which the function may not operate correctly
In the following situations, the camera sensor may be unable to recognize
lane markers causing the lane departure warning function to operate incor-
rectly. However, this does not indicate a malfunction.
●When there are shadows on the road running parallel with lane markers, or
if a shadow covers the lane markers
● When driving through an area with no lane markers, such as a toll booth, a
crossing or before a ticket checkpoint
● When the lane markers are broken, Botts’ dots (raised pavement markers)
or stones
● When lane markers are obscured or partially obscured by sand, dirt, etc.
● When driving on a road surface that is wet due to rain, previous rainfall,
standing water, etc.
● When the lane markers are yellow (These may be more difficult for the sys-
tem to recognize compared to white markers.)
● When the lane markers are on a curb, etc.
● When driving on a particularly bright road surface, such as concrete
● When driving on a road surface that is bright due to reflected light
● When driving in a location where the light level changes rapidly, such as the
entrance to or exit from a tunnel
● When sunlight or the headlights of oncoming vehicles are shining directly
into the camera lens
● When driving on roads that are branching or merging
● When driving on winding roads or roads that are uneven
● When driving on rough or unpaved roads
● When driving on a sharp curve
● When lane markers are extremely narrow or extremely wide
● When the vehicle leans to one side an unusual amount due to a heavy load
or improper tire inflation pressure
● When the following distance between your vehicle and the vehicle ahead is
extremely short
● When the vehicle experiences strong up-and-down motion such as when
driving on an extremely rough road or on a seam in the pavement
● When headlight brightness at nighttime is reduced due to dirt on the lenses,
or when the headlights are misaligned
■ When changing the tires
Depending on the tires used, sufficient performance may not be maintainable.

WARNING
■Replacing tires
Make sure that all tires are of the specified size, brand, tread 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 different tires
are installed on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.
