■Driving range
■Elapsed time
■Tire inflation pressureDisplays the estimated
maximum distance 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 diff er from that displayed.
• When only a small amount of fuel is added to the tank, the display may not be updated.
When refueling, turn the “START STOP ENGINE”
<“POWER”> switch off. If the vehicle is refueled
without turning the “START STOP ENGINE”
<“POWER”> switch off, the display may not be
updated.

For the vehicles with a full-size spare tire: The inflation
pressure of the spare tire will be displayed.

Driving
Control your speed and keep at a constant speed. Also, before stopping
at a toll booth or similar, allow plenty of time to release the accelerator and
gently apply the brakes. A greater am ount of electrical energy can be
retained when slowing down.
Use the air conditioning only when ne cessary. Doing so can help control
excessive gasoline consumption.
In summer: In high temperatures, use th e recirculated air mode. Doing so
will help to reduce the burden on th e 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 improved by avoiding overuse of
the heater.
Make sure to check the tire inflati on pressure frequently. Improper tire
inflation pressure can cause poor fuel consumption.
Also, as snow tires can cause large am ounts of friction, their use on dry
roads can lead to poor fuel consumptio n. Use a tire that is appropriate for
the season.
Carrying heavy luggage can lead to poor fuel consumption. Avoid carry-
ing unnecessary luggage. Installing a la rge roof rack can also cause poor
fuel consumption.

7-1. Maintenance and care
Cleaning and protecting the vehicle exterior
●Working from top to bottom, liberally apply water to the vehicle body,
wheel wells and underside of the vehicle to remove any dirt and dust.
●Wash the vehicle body using a sponge or soft cloth, such as a chamois.
●For hard-to-remove marks, use car wash soap and rinse thoroughly
with water.
●Wipe away any water.
●Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle body is
cool.
■Automatic car washes
●Fold the mirrors before washing the vehicle. Start washing from the front of the
vehicle. Make sure to extend the mirrors before driving.
●Brushes used in automatic car washes may scratch the vehicle surface and harm
your vehicle’s paint.
●Hybrid vehicles: Rear spoiler may not be washable in some automatic car washes.
There may also be an increased risk of damage to vehicle.
■High pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity of the win-
dows.
●Before using the car wash, check that the fuel filler door on your vehicle is closed
properly.
Perform the following to protect th e vehicle and maintain it in prime
condition:

Ti r e v a l v e
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure using the gauge gradations.
If the tire inflation pressure is not at the recommended level, adjust the
pressure.
If you add too much air, press the center of the valve to deflate.
After completing the tire inflation pressure measurement and adjust-
ment, apply soapy water to the valve and check for leakage.
Put the tire valve cap back on.
■Tire inflation pressure check interval
You should check tire inflation pressure every two weeks, or at least once a month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
●Reduced fuel efficiency
●Reduced driving comfort and tire life
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating, have it checked by your Lexus dealer.
