2004-4. Refueling
AVALON_HV_U (01999-07002)
After refueling, turn the fuel
tank cap until you hear a click.
Once the cap is released, it will
turn slightly in the opposite
direction.
Close the fuel filler door, and
press the center of the rear
edge of the fuel filler door until
you hear a click.
When you lock the doors, the fuel
filler door will lock also.
■Fuel filler door lock condition
The fuel filler door may not be locked even when the vehicle’s doors are
locked in the following conditions:
●When operating the door lock button inside the vehicle
● When the automatic door locking system is operated ( P. 113)
● When the fuel filler door is closed after the vehicle’s doors are locked

4-6. Driving tips
◆Using Eco drive mode
When using Eco drive mode, the torque corresponding to the accel-
erator pedal depression amount can be generated more smoothly
than it is in normal conditions. In addition, the operation of the air
conditioning system (h eating/cooling) will be minimized, improving
the fuel economy. ( P. 258)
◆Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the Hybrid System
Indicator within Eco area. ( P. 92)
◆Shift lever operation
Shift the shift lever to D when stopped at a traffic light, or driving in
heavy traffic etc. Shift the shift lever to P when parking. When using
the N, there is no positive effect on fuel consumption. In the N, the
gasoline engine operates but el ectricity cannot be generated. Also,
when using the air conditioning s ystem, etc., the hybrid battery
(traction battery) power is consumed.
◆Accelerator pedal/brake pedal operation
● Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual accelerati on and deceleration will make
more effective use of the electric motor (traction motor) without
having to use gasoline engine power.
● Avoid repeated acceleration. Repeated acceleration consumes
hybrid battery (traction battery) power, resulting in poor fuel con-
sumption. Battery power can be restored by driving with the
accelerator pedal slightly released.
Hybrid vehicle driving tips
For economical and ecological driv ing, pay attention to the fol-
lowing points:

2664-6. Driving tips
AVALON_HV_U (01999-07002)
◆When braking
Make sure to operate the brakes gently and in a timely manner. A
greater amount of electrical energy can be regenerated when slow-
ing down.
◆Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to bad fu el economy. Check traffic reports
before leaving and avoid delays as much as possible. When driving
in a traffic jam, gently release the brake pedal to allow the vehicle to
move forward slightly while avoi ding overuse of the accelerator
pedal. Doing so can help control excessive gasoline consumption.
◆Highway driving
Control and maintain the vehicle at a constant speed. Before stop-
ping at a toll booth or similar, allow plenty of time to release the
accelerator and gently apply the br akes. A greater amount of elec-
trical energy can be regenerated when slowing down.
◆Air conditioning
Use the air conditioning only when necessary. Doing so can help
reduce excessive gasoline consumption.
In summer: When the ambient temperature is high, use the recircu-
lated air mode. Doing so will help to reduce the burden on the air
conditioning system and reduce fuel consumption as well.
In winter: Because the gasoline eng ine will not automatically cut out
until it and the interior of the vehi cle 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 infl ation pressure frequently. Improper
tire inflation pressure can cause poor fuel economy.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead to poor fuel economy. Use tires that are appro-
priate for the season.

◆Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carry-
ing unnecessary luggage. Installing a large roof rack will also cause
poor fuel economy.
◆Warming up before driving
Since the gasoline engine starts up and cuts out automatically
when cold, warming up the engine is unnecessary. Moreover, fre-
quently driving short distances will cause the engine to repeatedly
warm up, which can lead to excess fuel consumption.

2785-1. Using the air conditioning system and defogger
AVALON_HV_U (01999-07002)
■Operation of the air conditioning system in Eco drive mode
In Eco drive mode, the air conditioning system is controlled as follows to pri-
oritize fuel efficiency:
●When the outside temperature exceeds 68°F (20°C), the air conditioning
system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
● It is possible to switch to outside air mode at any time by pressing
.
●Engine speed and compressor operation controlled to restrict heating/cool-
ing capacity
● Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
● Adjust the fan speed
● Turn off Eco drive mode
■ Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is touched.
■ Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the wind-
shield effectively.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ Windshield fog detection function
When automatic mode is set, the humidity sensor (P. 280) detects fog on
the windshield and controls the air conditioning system to prevent fog.
■ Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode to the recirculated air mode. This is effective in
preventing outside air from entering the vehicle interior. During cooling oper-
ation, setting the recirculated air mode will also cool the vehicle interior
effectively.
● Outside/recirculated air mode may automatically switch depending on the
temperature setting, outside temperature, pressure, engine coolant temper-
ature or inside temperature.

When the outside temperature exceeds 75°F (24°C) and the air condition-
ing system is on
●In order to reduce the air conditioning power consumption, the air condition-
ing system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
● Recirculated air mode is selected as a default mode when the power switch
is turned to ON mode.
● It is possible to switch to outside air mode at any time by pressing
.
■ When the outside temperature falls to nearly 32 F (0 C)
The dehumidification function may not operate even when is touched.
■ Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air mode.
● During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
● To reduce potential odors from occurring:
• This vehicle is equipped with a deodorizing charcoal air filter. This filter
should be inspected and replaced according to the maintenance sched-
ule. (Air conditioning filter: P. 370)
• It is recommended that the air conditioning system be set to outside air mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic
mode.

■ Handling of the air conditioning panel
The operating section of the air conditioning panel uses touch switch sensors.
In the following cases, incorrect operation or non-response may occur.
●If the surface of the touch switch is dirty or has liquid attached to it, incorrect
operation or non-response may occur.
● If the surface of the touch switch receives electromagnetic waves, incorrect
operation or non-response may occur.
● If wearing gloves during operation, non-response may occur.
● If fingernails are used to operate the system, non-response may occur.
● If a touch pen is used to operate the system, non-response may occur.
● If the palm of your hand touches the surface of the touch switch during oper-
ation, incorrect operation may occur.
● If the palm of your hand touches the surface of the touch switch, incorrect
operation may occur.
● If operations are performed quickly, non-response may occur.
