Driving 4-6.Driving tips
When using Eco drive mode, the
torque corresponding to the accelera-
tor pedal depression amount can be
generated more smoothly than it is in
normal conditions. In addition, the
operation of the air conditioning sys-
tem (heating/cooling) will be mini-
mized, improving the fuel economy.
( → P.298)
The Eco-friendly driving is possible by
keeping the indicate of Hybrid System
Indicator within Eco area. ( → P.78, 83)
Shift the shift position to D when
stopped at a traffic light, or driving in
heavy traffic etc. Shift the shift position
to P when parking. When using the N
position, there is no positive effect on
fuel consumption. In the N position, the
gasoline engine operates but electric-
ity cannot be generated. Also, when
using the air conditio ning system, etc.,
the hybrid battery (traction battery)
power is consumed.  Drive your vehicle smoothly. Avoid
abrupt acceleration and decelera-
tion. Gradual acceleration and
deceleration will make more effec-
tive use of the electric motor (trac-
tion 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 acceler-
ator pedal slightly released.
Make sure to operate the brakes gently
and in a timely manner. A greater
amount of electrical energy can be
regenerated when slowing down.
Repeated acceleration and decelera-
tion, as well as long waits at traffic
lights, will lead to bad fuel 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
avoiding overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consumption.Hybrid vehicle driving tips For economical and ecological
driving, pay attention to the follow-
ing points:
Using Eco drive mode
Use of Hybrid System Indicator
Changing the shift position Accelerator pedal/brake pedal
operation
When braking
Delays

308 4-6. Driving tips
LS500h_OM_OM50F42U_(U) Control and maintain the vehicle at a
constant speed. Before stopping at a
toll booth or similar, allow plenty of
time to release the accelerator and
gently apply the brakes. A greater
amount of electrical energy can be
regenerated when slowing down.
Use the air conditioning only when
necessary. Doing so can help reduce
excessive gasoline consumption.
In summer: When the ambient tem-
perature is high, use the recirculated
air mode. Doing so will help to reduce
the burden on the air conditioning sys-
tem and reduce fuel consumption as
well.
In winter: Because the gasoline engine
will not automatically cut out until it and
the interior of the vehicle are warm, it
will consume fuel. Also, fuel consump-
tion can be improved by avoiding over-
use of the heater.
Make sure to check the tire inflation
pressure frequently. Improper tire infla-
tion 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 appropriate for the
season. Carrying heavy luggage will lead to
poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large
roof rack will also cause poor fuel
economy.
Since the gasoline engine starts up and
cuts out automatically when cold,
warming up the engine is unnecessary.
Moreover, frequently driving short dis-
tances will cause the engine to repeat-
edly warm up, which can lead to excess
fuel consumption.Highway driving

Changing the air flow mode
→ P.326 ■
Switching between outside air and
recirculated air modes
Press the outside/recirculated air
mode switch. The mode changes as follows each time
the switch is pressed.
automatic mode → (outside air
mode) → (recirculated air mode)
→ automatic mode
When the system is switched to automatic
mode, the air conditioning system operates
automatically. ■
Defogging the windshield
Defoggers are used to defog the wind-
shield and front side windows.
Press the windshield defogger switch. Set the outside/reci rculated air mode
switch to outside air mode if the recircu-
lated air mode is used. (It may switch auto-
matically.)
To defog the windshield and the side win-
dows quickly, turn the air flow and tem-
perature up.
To return to the previous mode, press the
windshield defogger switch again when the
windshield is defogged.
■
Defogging the rear window and
outside rear view mirrors
Defoggers are used to defog the rear
window, and to remove raindrops, dew
and frost from the outside rear view
mirrors.
Press the rear window and outside rear
view mirror defoggers switch.
The defoggers will automatically turn off after a while. The operation time changes
according to the ambient temperature and
vehicle speed. ■

When the outside temperature exceeds
75°F (24°C) and the air conditioning
system is on ●
In order to reduce the air conditioning
power consumption, 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 the outside/recir-
culated air mode switch. ■
Fogging up of the windows
The windows will easily fog up when the
humidity in the vehicle is high. Turning “A/C”
on will dehumidify the air from the outlets
and defog the windshield effectively. ●
If you turn “A/C” off, the windows may fog
up more easily. ●
The windows may fog up if the recircu-
lated air mode is used. ■
Outside/recirculated air mode ●
When driving on dusty roads such as tun-
nels or in heavy traffic, set the out-
side/recirculated air mode switch to the
recirculated air mode. This is effective in
preventing outside air from entering the
vehicle interior. During cooling opera-
tion, setting the recirc ulated air mode will
also cool the vehicle interior effectively.
●
Outside/recirculated air mode may auto-
matically switch depending on the tem-
perature setting or the inside
temperature.
■
Registering air conditioning settings to
electronic keys
●
Unlocking the vehicle using an electronic
key and turning the power switch to ON
mode will recall that key’s registered air
conditioning settings.

Maintenance and care ■
Cleaning the air in take vent filters
1 Remove the grille.
2 Remove the filter.
3 Remove any dust and clogs from
the filter using a vacuum cleaner,
etc.Make sure to also remove dust and clogs
from the inner side of the air intake vent
grille.
If the filter is damaged, have it replaced by
your Lexus dealer.
4 Install the filter in its original posi-
tion, and then install the grille. 5 Start the hybrid system and check
that “Maintenance Required for
Traction Battery Cooling Parts See
Owner’s Manual” is no longer dis-
played on the multi-information dis-
play. It may take approximately 20 minutes after
the hybrid system is started until the warn-
ing message disappea rs. If the warning
message does not disappear, have the
vehicle inspected by your Lexus dealer. ■
Air intake vents maintenance ●
If the vehicle is driven with the air intake
vents clogged, the hybrid battery (trac-
tion battery) may not be cooled suffi-
ciently, possibly causing in fuel
consumption. ●
Depending on the conditions under
which the vehicle is used, the air intake
vents may need to be cleaned more reg-
ularly. ■
Cleaning the air intake vent filters ●
Improper handling of the air intake vent
grilles and filters may result in damage to
them. If you have any concerns about
cleaning the filter, contact your Lexus
dealer. ●
If the vehicle is driven with the air intake
vent filter clogged, the hybrid battery
(traction battery) ma y not be cooled suf-
ficiently, possibly causing an increase in
the fuel consumption and damage to the
hybrid battery (traction battery). ●
Depending on the conditions under
which the vehicle is used, the air intake
vent filters may need to be cleaned more
regularly.
■
If “Maintenance Required for Traction
Battery Cooling Parts See Owner’s
Manual” is displayed on the multi-infor-
mation display
●
It is possible the air intake vents or filters
are clogged due to accumulated dust.
Clean the air intake vents and filters,
referring to the cleaning method.
