HV Battery Charging
When high load operation is continued, the engine
does not stop to charge the HV battery even
if the vehicle is stopped, in order to keep the
HV battery charged to a given level. (when
ªREADYº light is ON.) ;however, the engine does
not charge the HV battery when the lever is
shifted into the ªNº position.
The engine speed may also be increased during normal
traveling in order to charge the HV battery.
1NZ-FXE Engine
The new Prius is fitted with a 1.5
gasoline engine which has been developed for the use with the TOYOTA
hybrid system. A mass of leading-edge technology has been implemented to achieve excellent fuel economy,
low emissions, light weight, compactness, and low vibration and noise.

4 Features of the 1NZ-FXE engine
1. Highly efficient and high expansion ratio gasoline engine
Adoption of a super fuel-efficient engine developed for use with THS. Its high expansion ratio cycle is achieved by applying the
Atkinson cycle*1 which obtains high thermal efficiency.
2. Reduction in frictional loss
The maximum engine speed is set at 4,500 rpm to reduce frictional resistance, thereby producing a highly efficient low-speed
engine.

An offset crankshaft with 12 mm deviation from the center axis of the cylinder bore is utilized to reduce frictional resistance
of the piston.

Frictional resistance is reduced through the use of low tension valve springs and piston rings.

Lightweight design has been adopted for reciprocating engine parts.
The above measures for reducing frictional loss contribute to improved fuel economy.
3. VVT-i (Variable Valve Timing -intelligent)
The timing of the opening and closing of the intake valves is controlled by the computer according to driving conditions, such
as engine speed and level of acceleration. Thus, smooth intake and exhaust are achieved to greatly improve torque in the low
and medium speed zones. This also contributes to better fuel economy and purification of exhaust gas. Then the VVT-i function
is used to reduce vibration when the engine starts.
4. Compact, lightweight, and low emission
Adoption of an aluminum cylinder block and compact design of parts. And, by positioning the catalytic converter near the engine
for a backwards exhaust layout, we have been able to reduce emissions when the engine is cold started.
*1 : Atkinson Cycle: Proposed by an English engineer named James Atkinson, this thermal cycle enables the compression stroke
and the expansion stroke of the mechanism to be set independently of each other.
Suspension
MacPherson strut type suspension with L-shape
lower arms has been adopted in the front and
torsion beam with toe control link suspension
in the rear. Also, each component part is opti-
mally located and tuned for both excellent con-
trollability and enhanced riding comfort.
EMPS (Electric Motor-assisted Power Steering)
System
Vehicle speed sensing type electric motor-assisted power steering is fitted as standard. Unlike conventional
hydraulic power steering, EMPS does not depend on an engine for its power source, providing a steering feel
in no way inferior to conventional steering when the engine has stopped. Thus it is suitable for the HV system.
Other merits include improved fuel economy through energy conservation, lighter weight, and no need to fill
the power steering fluid.

Air Conditioning
An automatic air conditioning has been adopted
in consideration to ease of use.

A clean air filter which removes pollen and
dust is included as a standard fitting for puri-
fying the air inside the cab.

Two air conditioning modes, A/C for eco-
nomical air conditioning and MAX for espe-
cially strong air conditioning, are provided.
Wireless Door Lock Remote Control System
With the wireless door lock remote control system, all the doors can be locked and unlocked by signals emitted
by the transmitter.
Power Window System
A power window system which enables all windows to be raised or lowered with switches has been adopted.
An auto up/down function and jam protection function have been added to the driver's power window.
HV Immobiliser System
HV immobiliser system will not allow the HV system to be started by duplicate key is used. This system
will permit the HV system to be started only when the ID code of the transponder chip impregnated in the
key matches the ID code registered beforehand in the transponder key amplifier.
Theft Deterrent System
When an attempt is made to forcibly enter the vehicle or open the hood or trunk lid without a key, or when
the battery terminals are removed and reconnected, this system sounds the horn and flashes the headlights,
taillights and emergency flashers for about 1 minute to alert the owner. At the same time, it locks all the
doors.
Storage Space
Ample storage space with an emphasis on practicality provided throughout the Prius.

Futuristic image and symmetry are reflected in the artistic
design of the new Prius.
Front Design
A short slanted hood highlights the singular front design.

The defined character lines from the front fender curving around to the rear give off a fresh appeal.

Crystal-look front combination lamps and compact grille finish off the masked look.
Rear Design
The simple rear design gives out an impression of stability.

Three-dimensional panel make-up produces a perfect balance in its feeling of presence and stability for
the rear view.

The rear combination lamps extend around to the sides, giving emphasis to the wide image.
