 TILT STEERING
The tilt steering is standard on all models.
The steering wheel position can be changed to any of 6 positions..
 POWER WINDOW SYSTEM
A power window system is standard on the LE and XLE grade models and optional on the CE grade model. The power
window system includes one±touch auto down and key±off operation functions. The one±touch auto down function
automatically opens the driver's side window fully. The key±off operation function makes it possible to operate the
power windows for approximately 45 seconds after the ignition key is turned to the ACC or LOCK position, if the
front doors are not opened.
 DOOR LOCK CONTROL SYSTEM
The door lock control system with 2±step unlock function is standard on the LE and XLE grade model and optional
as a set with the power window system on the CE grade model. With the 2±step function, turning the key once in
the driver's door unlocks the driver's door only. Turning it twice unlocks all the doors.
A key confinement prevention function is provided. When the door is opened and the door lock button is locked
with the key still inserted in the ignition key cylinder, the key confinement prevention mechanism immediately
turns the door lock button to unlock. This prevents the key from being inadvertently locked inside the vehicle.

 KEY REMINDER SYSTEM
All vehicles have a key reminder system as standard equipment. When the ignition key is left inserted in the ignition
key cylinder at ACC or LOCK positioon and the driver's door is opened, this system sounds a warning tone to remind
the driver to remove the ignition key.
 SRS AIRBAG
For all models, the new Camry has as standard equipment a driver's airbag in the steering wheel pad and a front
passenger airbag located in the instrument panel above the glove box.
 CRUISE CONTROL SYSTEM
The cruise control system is standard equipment on the LE and XLE grade model and an option on the CE grade
models. The main switch and control switch are on the a single lever, which is installed on the steering wheel and
can be operated easily.
 ILLUMINATED ENTRY SYSTEM
An illuminated entry system is standard equipment on the LE and XLE models. This system makes it easy to let
the Camry in and out at night, etc.
On the LE grade model, the ignition key cylinder illumination is turned on automatically when the door is opened.
When the door is closed, the ignition key cylinder illumination remains on for approximately 5 seconds, then goes
off automatically.
On the XLE grade model, the illuminated entry system turns on the dome light and ignition key cylinder
illumination for approximately 15 seconds after either door is closed when passengers are entering or leaving the
vehicle. While these lights are on for 15 seconds, if the ignition switch is turned to the ACC or ON position, or if
all doors are locked, the dome light and ignition key cylinder illuminatioons go off immediately.

 MAJOR DIFFERENCES
Major differences between the new 5S±FE engine and previous engine are listed below.
Item
Features
Engine ProperThe squish area of the combustion chamber in the cylinder head has been
optimised to improve torque in the low±to mid±speed range.
Cooling SystemAn aluminum radiator core is used for weight reduction.
Intake and Exhaust System
The ports of the manifold have been extended to improve torque in the low±
to mid±speed range.
The exhaust manifold is made of stainless steel plates for improve engine per-
formance and weight reduction.
Through the optimized allocation of the exhaust pipe supports, the number of
supports has been reduced from 5 to 4, thus reducing the noise and vibration
which are transmitted to the vehicle body.
Fuel SystemA fuel returnless system has been adopted to prevent the internal temperature
of the fuel tank from rising and to reduce evaporative emissions.
Ignition SystemThe DIS (Direct Ignition System) contributes to the powerful high output by
providing a powerful spark to the engine.
Engine MountingTo reduce noise and vibration and to improve drivability, the allocation of the
engine mounts*1 and their characteristics have been revised.
Engine Control System
The injection pattern for engine starting have changed form the 2 group
injection type to sequential multiport injection type.
In place of the oxygen sensor (bank 1, sensor 1), a new air fuel ratio sensor has
been adopted. *
2
The power steering idle±up control has been changed from the system using
an air control valve to the one using a pressure switch and an IAC valve.
Emission Control System
The EGR valve body has been changed from cast iron to aluminum alloy for
weight reduction.
A TWC (Three±Way Catalytic Converter) that is integrated with a stainless
steel exhaust manifold has been adopted.*
2
The TWC, which was previously installed below the exhaust manifold has
been discontinued.*3

 IGNITION SYSTEM
1. General
A DIS (Direct Ignition System) has been adopted in the new 5S±FE engine. The DIS in new 5S±FE engine is a
2±cylinder simultaneous ignition system which ignites 2±cyliners simultaneously with one ignition coil. In addition,
the igniter is integrated in the ignition coil for simpler system configuration.
2. Ignition Coil
Construction of the DIS system of the 5S±FE engine consists of 2 sets of ignition coils integrated with igniter and
with the high±tension cords attached directly onto the ignitioncoil.

 ENGINE CONTROL SYSTEM
1. General
The engine control system of the new 5S±FE engine is basically the same in construction and operation as that of the
previous 5S±FE engine, except fo rthe changed listed bleow.
The exhaust emissions has been reduced through the adoption of the sequential multiport fuel injection system for
engine starting and the air±fuel ratio sensor*
2
The function of an air conditioning amplifier has been internally added to the ECM.
The engine control system of the new 5S±FE engine and previous 5S±FE engine and previous 5S±FE engine are
compared below.
