When stopped/during start off
The gasoline engine stops* when the vehicle is stopped.
During start off, the electric motor (traction motor) drives the
vehicle. At slow speeds or when traveling down a gentle
slope, the engine is stopped* and the motor is used.
When shift position is in N, the hybrid battery (traction bat-
tery) will not be charged. Thus, shift to P when the vehicle is
stopped. In addition, when driving in heavy traffic, use D or
B.
*:However, when the hybrid battery (traction battery) need to
be charged or while the engine is being warmed up, the gas-
oline engine may not stop automatically.
During normal driving
The gasoline engine is predominantly used. The electric
motor (traction motor) charges the hybrid battery as neces-
sary.
When accelerating sharply
The power of the hybrid battery (traction battery) is added to
that of the gasoline engine via the electric motor (traction
motor).
When braking (regenerative braking)

CT200h_EE (OM76041E)
Regenerative braking
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 battery).
The accelerator pedal is released while driving with the shift position in
D or B.
The brake pedal is depressed while driving with the shift position in D or
B.
EV indicator
Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop
automatically in the following conditions:
During gasoline engine warm-up
During hybrid battery (traction battery) charging
When the temperature of the hybrid battery (traction battery) is high or
low
When the heater is switched on
The EV indicator comes on when driving
the vehicle using only the electric motor
(traction motor).

Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction battery), the bat-
tery does not need to be charged from an outside source. However, if the
vehicle is left parked for a long time the hybrid battery will slowly dis-
charge. For this reason, be sure to drive the vehicle at least once every few
months for at least 30 minutes or 16 km (10 miles). If the hybrid battery
becomes fully discharged and you are unable to jump-start the vehicle with
the 12-volt battery, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
Charging the 12-volt battery
P. 6 2 3
After the 12-volt battery has discharged or has been changed or removed
The gasoline engine may not stop even if the vehicle is running on the
hybrid battery (traction battery). If this continues for a few days, contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional.

Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able
to move. 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.
Sounds may be heard from the hybrid battery (traction battery) behind
the rear seats when the hybrid system starts or stops.
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 and accelerator is loosened.
Other sounds, such as motors and mechanical noises, may be heard from
the brake system when the brake pedal is depressed.
Vibration may be felt when the gasoline engine starts or stops.
Cooling fan sounds may be heard from the air intake vent on the side of
rear right seatback.
Maintenance, repair, recycling, and disposal
Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional regarding maintenance, repair, recycling and dis-
posal. Do not dispose of the vehicle yourself.
Customization
Settings (e.g. on/off operation of the EV drive mode indicator) can be
changed.

Hybrid battery air vent
There is an air intake vent on
the side of the rear right seat-
back for the purpose of cooling
the hybrid battery (traction bat-
tery). If the vent become
blocked, the hybrid battery may
overheat, leading to a reduction
in hybrid battery output.
Emergency shut off system
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks off the high voltage current and
stops the fuel pump to minimize the risk of electrocution and fuel
leakage. If the emergency shut off system activates, your vehicle
will not restart. To restart the hybrid system, contact any autho-
rized Lexus dealer or repairer, or another duly qualified and
equipped professional.
