Before driving
■
Air conditioning on/off
Switch the air conditioning ( ) to off when it is not needed.
Doing so can help control excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode.
Doing so will help to reduce t he burden on the air conditioner
and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut
out until the gasoline engine and the interior of the vehicle are
warm, it will consume fuel. Also, fuel consumption can be
improved by avoiding overuse of the heater.
■ Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently.
Improper tire inflation pressure can cause poor fuel consump-
tion.
Also, as snow tires can cause lar ge amounts of friction, their use
on dry roads can lead to poor fuel consumption. Use a tire that is
appropriate for the season.
■ Luggage
Carrying heavy luggage can lead to poor fuel consumption.
Avoid carrying unnecessary luggage. Installing a large roof rack
can also cause poor fuel consumption.
■ Warming up before driving
Since the gasoline engine starts up and cuts out automatically
when cold, warming up the engine is unnecessary. Moreover,
frequently driving s hort distances will ca use the engine to
repeatedly warm up, which can lead to poor fuel consumption.

When driving
NOTICE
■In the following situations, the LKA will not work, or will not perform
reliably:
● When lane markers are interrupted or are not present, such as before a
tollbooth.
● When lane markers are only on one side of the road.
● When driving on a sharp curve.
● When lanes 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 lane markers are broken, “Botts’ dots”, or “Raised pavement
marker”.
● When lane markers are obscured or partially obscured by sand, dirt, 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.

CAUTION
■Replacing tires
Make sure that all tires are of the specified size and of the same 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 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.
