501-1. Hybrid system
■ Checking tire inflation pressure Make sure to check the tire inflation pressure frequently.
Improper tire inflation pressure can cause poor fu el consumption.
Also, as snow tires can cause large amounts of friction, their use on dry
roads 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 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 short
distances will cause the engine to repeatedly warm up, which can lead to
poor fuel consumption.

2102-2. Instrument cluster
■ 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
one second when the average vehicle speed is displayed.
■ Cruising range
Displays the estimated maximum distan ce that can be driven with the
quantity of fuel remaining • This distance is computed based on your average fuel consumption. As
a result, the actual distance that can be driven may differ from that dis-
played.
• When only a small amount of fuel is added to the tank, the display may
not be updated.
When refueling, turn the “POWER” switch off. If the vehicle is refueled
without turning the “POWER” switch off, the display may not be
updated.
■ Tire inflation pressure
Displays inflation pressure of each tire. There is no correlation between
the order of the displayed values and the tire positions. If the inflation pressure of any tire drops a certain amount below the tire infla-
tion pressure value currently memorized in the system, the displayed values
will be highlighted.
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 inflation pressure has been adjusted.
If the tire pressure warning light is on or flashing, a message describing the
situation will be displayed.

2752-4. Using other driving systems
2
When driving CAUTION■
When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may cause
an accident, resulting in death or serious injury. Exercise particular care when the
indicator light flashes.■
When the TRAC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are the systems to help ensure vehicle stability and driving force, do not turn
the TRAC/VSC systems off unless necessary.■
Replacing tires
Make sure that all tires are of the same 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 suspension
Using tires with any kind of problem or modifying the suspension will affect the driv-
ing assist systems, and may cause a system malfunction.

Vehicle exterior Items Check points
Doors • Do the doors operate smoothly?
Engine hood • Does the engine hood lock system
work properly?
Fluid leaks • There should not be any signs of
fluid leakage after the vehicle has
been parked.
Ti r e s • Is the tire inflation pressure cor-
rect?
• The tires should not be damaged or
excessively worn.
• Have the tires been rotated
according to the maintenance
schedule?
• The wheel nuts should not be loose.
Windshield wipers • The wiper blades should not show
any signs of cracking, splitting,
wear, contamination or deforma-
tion.
• The wiper blades should clear the
windshield without streaking or
skipping.
