■Running out of fuel
When the vehicle has run out of fuel and the
hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to
make the low fuel level warning light
(  P.338) go off. If there is only a small
amount of fuel, the hybrid system may not
be able to start. (The standard amount of fuel is about 3.3 gal. [12.6 L, 2.8 Imp.gal.],
when the vehicle is on a level surface. This
value may vary when the vehicle is on a
slope. Add extra fuel when the vehicle is
inclined.)
■Electromagnetic waves
●High voltage parts and cables on hybrid
vehicles incorporate electromagnetic
Hybrid system precautions (LC500h)
Take care when handling the hybrid system,
as it is a high voltage system (about
650 V at maximum) as well as contains parts that become extremely hot when
the hybrid system is operating. Obey th e warning labels attached to the vehi-
cle.

LC500_LC500h_OM_OM11405U_(U)
1Normal mode/Custom mode
Normal mode and custom mode
are selected by pressing the driving
mode select switch. Each time the
switch is pressed, the driving mode
changes between normal mode
and custom mode. When custom
mode is selected, the “Custom”
indicator comes on.
Press the switch to change the driving
mode to normal mode when not in normal
mode.
•Normal mode
Provides an optimal ba lance of fuel econ-
omy, quietness, and dynamic performance.
Suitable for city driving. When the shift position is in D, an appropri-
ate gear for sporty driving may automati-
cally be selected according to driver
performance and driving conditions.
• Custom mode
Allows you to drive with the power train,
chassis and air conditioning system func-
tions set to your preferred settings.
Custom mode settings can only be
changed on the drive mode customization
display of the Center Display. (
P.237)
2 Comfort mode
By controlling the suspension, rid-
ing comfort is fu rther enhanced.
Suitable for city driving.
When not in comfort mode and the driving
mode select switch is turned forward, the
“Comfort” indicator comes on.
3 Eco drive mode
Helps the driver accelerate in an
eco-friendly manner and improve
fuel economy through moderate
throttle characteristics and by con-
trolling the operation of the air con-
ditioning system (heating/cooling).
When in comfort mode, if the driving mode
select switch is turned forward, the “Eco”
indicator comes on.
4Sport mode
•SPORT S mode
Controls the transmission and engine to
provide quick, powerful acceleration. This
mode is suitable for when agile driving
response is desired, such as when driving
on roads with many curves.
When not in SPORT S mode, if the driving
mode select switch is turned backward, the
“Sport S” indicator comes on.
•SPORT S+ mode
Provides earlier downshift timing than
SPORT S mode in order to maintain a high

The driving modes can be selected
to suit driving condition.

engine speed and provides faster gear
changes. This mode also changes the
steering feel, suspension control and
VDIM control, making it suitable for pow-
erful sporty driving.
When in SPORT S mode, if the driving
mode select switch is turned backward, the
“Sport S+” indicator comes on.
■Operation of the air conditioning sys-
tem in Eco drive mode
Eco drive mode controls the heating/cool-
ing operations and fan speed of the air con-
ditioning system to enhance fuel efficiency.
To improve air condit ioning performance,
perform the following operations:
●Turn off eco air conditioning mode
(  P.246)
●Adjust the fan speed ( P.245)
●Turn off Eco drive mode ( P.208)
■Automatic deactivation of sport mode
and custom mode
If the engine switch is
turned off after drivin g in sport mode or
custom mode, the drive mode will be
changed to normal mode.
■Driving mode pop-up display
When the driving mode is changed, the
selected driving mode will be temporarily
displayed on the side display. ( P.239)
For custom mode, select “Setting” on the
display to customize the driving mode.

■Display
When the sensors detect an obstacle, a
graphic is shown on the multi-informa-
tion display, head-up display and Cen-
ter Display depending on the position
and distance to the obstacle.
Intuitive parking assist*
The distance from your vehicle to
nearby obstacles when parallel
parking or maneuvering into a
garage is measured by the sensors
and communicated via the multi-
information display, head-up dis-
play (if equipped), Center Display
and a buzzer. Always check the sur-
rounding area when using this sys-
tem.

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.208)
The Eco-friendly driving is possible by
keeping the indicate of Hybrid System
Indicator within Eco area. ( P.72)
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:

2324-6. Driving tips
LC500_LC500h_OM_OM11405U_(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.
