* status.
Regenerated energy will be used to
charge the hybrid battery (traction bat-
tery).
Hybrid Eco area
Shows that gasoline engine power is
not being used very often.
The gasoline engine will automatically
stop and restart under various condi-
tions.
Eco area
Shows that the vehicle is being driven
in an Eco-friendly manner.
By keeping the bar display within Eco
area, more Eco-friendly driving can be
achieved.
Power area
Shows that an Eco- friendly driving
range is being exceeded (during full
power driving etc.)
*: When used in this manual, regeneration
refers to the conversion of energy cre-
ated by the movement of the vehicle into
electrical energy.
Hybrid System
Your vehicle is a hybrid vehicle. It has charac teristics different from conventional vehicles.
Be sure you are closely familiar with the characterist ics of your vehicle, and operate it with
care.
The hybrid system combines the use of a gaso line engine and an electric motor (traction
motor) according to driving conditions, impr oving fuel efficiency and reducing exhaust
emissions.
For details, refer to the “OWNER’S MANUAL”.

When driving with the gasoline engine stopped, a sound, which changes in accordance with
the driving speed, will be played in order to warn people nearby of the vehicle’s approach.
The sound will stop when th e vehicle speed exceeds approximately 22 mph (35 km/h).
If the shift position is in N, the hybrid battery (traction battery) will not be charged. To help
prevent the battery from discharging, avoid leaving the N position selected for an extended
period of time.
In the following situations, kinetic energy is converted to electric energy and deceleration
force can be obtained in conjunction with the recharging of the hybrid battery (traction bat-
tery).
● The accelerator pedal is released while dr iving with the shift position in D or M.
● The brake pedal is depressed while driving with the shift position in D or M.

There may be no engine sound or vibration even though the vehicle is able to move with the
“READY” indicator is illuminated. For safety, apply the parking brake and make sure to shift
the shift position to P when parked.
The following sounds or vibrations may occur when the hybrid system is operating and are
not a malfunction:
● Motor sounds may be heard from the engine compartment.
● Relay operating sounds such as a snap or so ft clank will be emitted from the hybrid bat-
tery (traction battery), behind the rear se ats, when the hybrid system is started or
stopped.
● Sounds may be heard from the hybrid battery (traction battery) behind the rear seats
when the hybrid syst em starts or stops.
● Sounds from the hybrid system may be heard when the trunk lid is open.
● Sounds may be heard from the transmission when the gasoline engine starts or stops,
when driving at low speeds, or during idling.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard due to regenerative braking when the brake pedal is depressed or
as the accelerator pedal is released.
● Vibration may be felt or sounds may be hear d when the gasoline engine starts or stops.
● Cooling fan sounds may be heard from the air intake vents on the both sides of the rear
seatback.
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 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 3.4 gal. [13 L, 2.8 Imp. gal.], when the vehicle is on a level su rface. This value
may vary when the vehicle is on a slope. Add extra fuel when the vehicle is inclined.)
A message is automatically disp layed when a malfunction occurs in the hybrid system or an
improper operation is attempted.
If a warning message is shown on the multi-
information display, read the message and
follow the instructions.

LS500h_QG_U
Only in an emergency, such as if it becomes impossible to stop the vehicle in the normal way,
stop the vehicle using the following procedure:
1Steadily step on the brake pedal with both feet and firmly depress it.
Do not pump the brake pedal repeatedly as this will increase the effort required to slow
the vehicle.
2Shift the shift position to N.
 If the shift position is shifted to N
3After slowing down, stop the vehicle in a safe place by the road.
4Stop the hybrid system.
 If the shift position cannot be shifted to N
3Keep depressing the brake pedal with both feet to reduce vehicle speed as much as
possible.
4To stop the hybrid system, press and
hold the power switch for 2 consecu-
tive seconds or more, or press it briefly
3 times or more in succession.
5Stop the vehicle in a sa fe place by the road.
Turns EV drive mode on/off
When EV drive mode is turned on, the EV
drive mode indicator will come on. Pressing
the switch when in EV drive mode will
return the vehicle to normal driving (using
the gasoline engine and electric motor
[traction motor]).
If your vehicle has to be stopped in an emergency
EV Drive Mode
In EV drive mode, electric power is supplied by the hybrid battery (traction battery), and
only the electric motor (traction mo tor) is used to drive the vehicle.

■Snow mode
Snow mode can be selected to suit the condit ions when driving on slippery road surfaces,
such as on snow.
Turn the snow mode switch backward.
The snow mode indicator illuminates.
Turn the snow mode switch backward again
to return to normal mode.
When the “-” paddle shift switch is operated, the shift range switches to a range that enables
engine braking force that is suit able to driving conditions. When the “+” paddle shift switch is
operated, the shift range switches to a range that is one range higher than the current range.

The selected shift range, from D1 to D10,
will be displaye d on the meter.
A lower shift range will provide greater engine braking forces than a higher shift range.
