Hybrid System
This illustration is for explanation only and
may differ depending on the specifications
of the vehicle.
Charge area
Shows regeneration
* status.
Eco area
Shows that the vehicle is being driven
in an Eco-friendly manner.
Power area
Shows that an Eco- friendly driving
range is being exceeded (during full
power driving etc.)
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.
• By keeping the indicator needle within Eco area, more Eco-fr iendly driving can
be achieved.
• Charge area indicates regeneration
* sta-
tus. Regenerated energy will be used to
charge the hybrid battery (traction bat-
tery).
*: 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 electric vehicle. It has characteristics different from conventional
vehicles. Be sure you are closely familiar with the characteristics 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.
This sound may be heard inside the vehicle. The sound will stop when the 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 a certain
amount 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).
• RX350h: The accelerator pedal is released while driving with the shift position in D or S.
• RX500h: The accelerator pedal is released while driving with the shift position in D or M.
• RX350h: The brake pedal is depressed while driving with the shift position in D or S.
• RX500h: The brake pedal is depressed while driving with the shift position in D or M.

Because there is no engine sound or vibration, it is easy to mistake the hybrid electric vehi-
cle for being off when it is actu ally still running, as indicated by the “READY” indicator being
illuminated. For safety, make sure to always shift the shift position to P and apply the parking
brake 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.
• Sounds may be heard from the hybrid battery (traction battery) behind the rear seats when the hybrid syst em starts or stops.
• Relay operating sounds such as a snap or soft clank will be emitted from the hybrid battery
(traction battery), under the rear seats, when the hybrid sy stem is started or stopped.
• Sounds from the hybrid system may be heard when the back door 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 when the gasoline engi ne starts or stops.
• Cooling fan sounds may be heard from th e air intake vents under the rear seats.
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 2.6 gal. [9.8 L, 2.2 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.)

After using the mechanic al key, store it in
the electronic key. Carry the mechanical
key together with the electronic key. If the
electronic key battery is depleted or the
entry function does not operate properly,
you will need the mechanical key.
