1-1. Hybrid system
■Air conditioning
Use the air conditioning only when necessary. Doing so can help control
excessive gasoline consumption.
In summer: In high temperatures, use the r
ecirculated air mode. Doing so
will help to reduce the burden on the air conditioner and reduce fuel con -
sumption 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 con -
sume fuel. Also, fuel consumption can be impr
oved by avoiding overuse of
the heater.
■ Checking tire inflation pressure
Make sure to check the tire inflatio n pressure frequently. Improper tire
inflation pressure can cause poor fuel consumption.
Also, as snow tires can cause large amounts of friction, their use on dry
r
oads can lead to poor fuel consumptio n. Use a tire that is appropriate for
the season.
■ Luggage
Carrying heavy luggage can lead to poor fuel consumption. Avoid carry-
ing unnecessary luggage. Installing a la r
ge 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 short
distances will cause the engine to repeatedly warm up, which can lead to
poor fuel consumption.

When driving
■Average vehicle speed
Displays the average vehicle speed since the function was reset
The function can be reset by pushing the “ENTER” switch for longer than 1
second when the average vehicle speed is displayed.
■ Outside temperature
Displays the outside temperature
■ T
ire inflation pressure
Displays inflation pressure of each tir
e. There is no correlation between
the order of the displayed values and the tire positions.
It may take a few minutes to display the tire inflation pressure after the
“POWER” switch is turned to ON mode. It may also take a few minutes to
display the tire inflation pressure after the inflation pressure has been
adjusted.
■Electronic feature control can be turned on/off when
The “POWER” switch is in ON mode.
■Conditions for ending electronic feature control
In the following situations, the electronic feature control will end:
●The menu switch is pressed
●The radar cruise control is operated (if equipped)
●The lane keeping assist is operated (if equipped)
●Intuitive parking assist starts operating (if equipped)
●No action is performed for some time after the electronic feature control
screen is displayed
●A warning message appears after the electronic feature control screen is dis -
played

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 brig ht 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 pavement lane markers are difficult to see due to rain, snow, fog, etc.
●When driving on a road surface that is wet due to rain, previous rainfall, standing
water, etc.
●When the vehicle experiences strong up-a nd-down motion such as when driving
on an extremely rough road or on a seam in the pavement.
●When headlight brightness is reduced du e to dirt on the lenses, or when the
headlights are misaligned.
●When driving with a strong crosswind.

When driving
CAUTION
■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 and VSC systems will not function correctly if different tires are installed
on the vehicle.
Contact your Lexus dealer for further info rmation 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 driv-
ing assist systems, and may cause a system to malfunction.

2-5. Driving information
CAUTION
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or serious
injury.
●Use tires of the size specified.
●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 accidents.
Failure to do so may result in the vehicle being unable to be driven safely, and may
cause death or serious injury.
●Do not drive in excess of the speed limit specified for the tire chains being used,
or 30 mph (50 km/h), whichever is lower.
●Avoid driving on bumpy road surfaces or over potholes.
●Avoid sudden turns and braking, as use of chains may adversely affect vehicle
handling.
●Slow down sufficiently before entering a curve to ensure that vehicle control is
maintained.
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tire s from Lexus dealers or legitimate tire
retailers.
This is because the removal and attachment of snow tires affects the operation of
the tire pressure warning valves and transmitters.
■Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly when
tire chains are fitted.
