GENERAL INFORMATION

Column switch has a function to ensure the driver's
safety during frontal collision of vehicle.

Function

Front of vehicle

Column switch

If the column switch is moved to the front of the vehi-
cle and hit on the instrument panel or meter bezel by
the frontal collision of vehicle, the steering wheel is
moved to the front of the vehicle because the right
and left levers fall down, ensuring the driver's safety.
In addition, the column switch secures the rigidity
that the levers do not fall down by the normal opera
tion, however, it cannot be reused after the deforma-
tion.

HEATER, AIR CONDITIONING AND VENTILATION

GENERAL DESCRIPTION

GENERAL DESCRIPTION

The blower, heater, and evaporator have been inte­grated with the heater and A/C system to achieve a
greater fan power and noise reduction.

FEATURES

.

ENHANCEMENTS IN COMFORT

• With the adoption of fully-automatic A/C, the out­side/inside air circulation switching, air outlet, and
outlet air temperature are automatically con
trolled according to the ambient temperature,
solar radiation, and passenger compartment tem
perature so that the optimum air conditioner is
achieved. <Automatic A/C>

• By the adoption of clean air filter, the air quality
inside the passenger compartment has been
enhanced.

.

ENHANCEMENTS IN OPERATION
PERFORMANCE

• Operability has been enhanced by the adoption
of large triple dial.

• Customise function has been added for the
enhanced convenience.

.

ENHANCEMENTS IN FUEL ECONOMY

• The high efficiency compressor with a 2-step pro­file oil separator has been installed, thus enhanc­ing the fuel economy.

• The idle-up speed is controlled in two steps to
secure the air cooling performance during sum
mer and to enhance the fuel economy in the sea­sons with moderate temperature.

-

-

M2551001500040

• Enhancement of fuel economy by the cooling fan
control depending on the refrigerant pressure and
vehicle speed.

.

ENHANCEMENT IN SAFETY

• A/C system is stopped when the air bags are
deployed.

• Crushable space has been adopted to heater unit
to reduce the risk of passenger injuries in case of
a collision.

.

-

GLOBAL ENVIRONMENT PROTECTION

• New refrigerant system (HFC134a) has been
adopted.

• By the optimisation of A/C system, the refrigerant
charging amount has been reduced.

• Clean air filter media and its cover are separated
to reduce waste materials.

.

ENHANCEMENTS IN SERVICE QUALITY

• Reduction of refrigerant gas leakage and
enhancement in serviceability by incorporating
condenser and receiver

• Clean air filter is installed to the backside of glove
box to facilitate the filter replacement.

.

ENHANCEMENTS IN RESPONSIBILITY

Reliable information transmission is achieved by
connecting A/C-ECU and each ECU via CAN com
munication.

idle-up speed of the engine is controlled in two steps
depending on the A/C load to secure the air cooling
performance during summer and to enhance fuel
economy in seasons with moderate temperature.

.

DETECTION CONTROL FOR
REFRIGERANT LEAKS

A/C-ECU determines if the refrigerant amount is less
than specified or refrigerant pressure is abnormal by
using the ambient temperature (ambient temperature
sensor to measure refrigerant inflation rate) and
refrigerant pressure (measured by the A/C pressure
sensor). When refrigerant amount or refrigerant pres
sure is judged abnormal, the compressor is cut-off to
protect the A/C system.

NOTE: When abnormality occurs, the A/C indicator
flashes.

High efficiency compressor with integrated oil sepa­rator has been adopted to enhance fuel economy by
reducing the A/C operating rate.

2-STEP PROFILE COMPRESSOR

M2551001100268

MAGNETIC CLUTCH WITH THERMAL
FUSE

At the compressor lock, the thermal fuse integrated
in the magnet clutch is blown due to the frictional
heat against the compressor in order to reduce risk
of the drive belt breakage. The thermal fuse, together
with the coil, is coated with resin to enhance resis
tance to corrosion.

The centre area of the scroll in the compressor pro­vides 2-step profile, and thickness of area "B" shown
in the figure has been increased to enhance
strength. With this feature, thickness of area "A"
shown where lesser load is applied is reduced, thus
compressor performance is enhanced by compress
ing refrigerant even in central area, comparing to the
previous model.

GENERAL INFORMATION

For the accelerator system, an electronic throttle
valve control system has been adopted, disposing of
an accelerator cable. This system detects the accel
erator pedal travel by using a accelerator pedal posi­tion sensor (APP sensor) in the accelerator pedal
assembly for electronic control of the throttle valve
angle.

AUTO-CRUISE CONTROL SYSTEM

GENERAL INFORMATION

By using the auto-cruise control system, the driver
can drive at preferred speeds in a range of approxi
mately 40 to 200 km/h (25 to 125 mph) without
depressing the accelerator pedal.

For this auto-cruise control system, in conjunction
with the electronic throttle valve control system, the

­engine control module (ECM) electronically controls
the throttle valve.

SYSTEM FUNCTIONS

.

SET FUNCTION

1. During driving with the vehicle speed range from

approximately 40 to 200 km/h (25 to 125 mph),
press and release the "COAST/SET" switch.

2. The vehicle speed when the "COAST/SET" switch

is released is memorized. Thereafter, the constant
speed driving is performed at that vehicle speed.

3. When the "COAST/SET" switch is operated

during the driving with the vehicle speed of
approximately 200 km/h (125 mph) or more, the
constant speed driving will not be performed.

.

COAST FUNCTION

1. When the "COAST/SET" switch is continuously

pressed for 0.5 seconds or longer during constant
speed driving, the throttle valve becomes fully
closed while the switch is pressed, and the
vehicle is decelerated.

2. When the "COAST/SET" switch is released, the

vehicle speed at that time is now memorized.
Thereafter, the constant speed driving is
performed at that vehicle speed.

3. Also when the "COAST/SET" switch is pressed

for less than 0.5 second, the vehicle is
decelerated 1.6 km/h (1 mph) from the vehicle
speed of constant speed driving, and the
decelerated vehicle speed is now memorized.
Thereafter, the constant speed driving is
performed at that vehicle speed.

4. When the "COAST/SET" switch is continuously

pressed and the vehicle speed is decelerated to
approximately 40 km/h (25 mph) or less, the set
function and coast function are cancelled, and the
constant speed driving is cancelled.

.

RESUME FUNCTION

1. When the "CANCEL" switch is pressed or the

brake pedal is depressed during the constant
speed driving, it cancels the constant speed
driving.

2. Subsequently, when the "ACC/RES" switch is

pressed during driving with the vehicle speed of
approximately 40 km/h (25 mph) or more, the
constant speed driving is performed with the
vehicle speed memorized at the last cancellation
of constant speed driving.

.

ACCEL FUNCTION

1. When the "ACC/RES" switch is continuously
pressed for 0.5 second or more during constant
driving, it accelerates the vehicle with specified
acceleration while the switch is pressed.

2. Then, when the "ACC/RES" switch is released,
the vehicle speed at that time is now memorized.
Thereafter, the constant speed driving is
performed at that vehicle speed.

3. Also, when the "ACC/RES" switch is pressed for
less than 0.5 second, the vehicle is accelerated

1.6 km/h (1 mph) from the vehicle speed of
constant speed driving, and the accelerated
vehicle speed is now memorized. Thereafter, the
constant speed driving is performed at that
vehicle speed.

4. It is possible to keep pressing the "ACC/RES"
switch until the vehicle speed is accelerated to
approximately 200 km/h (125 mph) or above.
However, after the "ACC/RES" switch is released,
the vehicle speed of approximately 200 km/h (125
mph) becomes the newly memorized vehicle
speed. Thereafter, the constant speed driving is
performed at that speed.

.

CANCEL FUNCTION

When any of the following conditions are satisfied,
the constant speed driving will be cancelled.

• The auto-cruise control system is stopped by the
pressing the "ON OFF" switch.

• The "CANCEL" switch is pressed.

• The brake pedal is depressed.

• The clutch pedal is depressed <M/T>.

• The selector lever is shifted to the "N" position

<CVT>.

• The vehicle speed becomes approximately 40
km/h (25 mph) or less.

• The vehicle speed is reduced 15 km/h (9 mph) or
more from the speed at which the constant speed
driving was started.

• An abnormality occurs in the vehicle speed sig­nal.

• The engine coolant temperature becomes abnor­mally high.

• An abnormality occurs to the ECM.

• An abnormality occurs to the TCM <CVT>.

• An abnormality occurs to the CAN communica-

tion.

FAIL-SAFE FUNCTION

When any of the following conditions are satisfied,
the auto-cruise control system function is stopped
until the system returns to normal. Also, when any of
the conditions are satisfied during the constant
speed driving, the constant speed driving is can
celled immediately.

• An abnormality occurs to the auto-cruise control
switch.

• An abnormality occurs to the stoplight switch.

When any of the following conditions are satisfied,
stop the vehicle once and turn the ignition switch to
"LOCK" (OFF). Otherwise, even when the system
returns to normal, the auto-cruise control system
function will continue to be stopped. Also, when any
of the conditions are satisfied during the constant
speed driving, the constant speed driving is can

method and reduces exhaust gas (NOx) and fuel consumption.
The EGR valve drives the stepper motor based on the signal
from ECM. When stepper motor rotor turns in clockwise or
anti-clockwise direction, the shaft fitted with a rotor and a screw
expands and contracts and the movement of the shaft causes
the valve to go up and down. Thus, EGR path gap is controlled
minutely. The stepper motor turns 15
motor turns forward or back only up to the angle dictated by the
number of pulse signals (number of steps) from the ECM. In
other words, increase and decrease of the EGR flow volume
depends on the number of signals (number of steps) from
ECM. ECM changes current flow to the 4 coils (A, B, C, D) in
the stepper motor in sequence according to the phase pattern

The HC trap catalytic converter is installed in the center of

consists of the HC trap catalyst and the three-way catalysts,
which are the monolith type; the catalyst element is attached to
the honeycomb catalyst surface. The HC trap catalyst and the
three-way catalysts are held by the heat-insulating mat and
installed in the shell. The HC trap catalyst temporarily absorbs
the exhaust HC from the engine within the temperature range
in which the three-way catalyst is not activated, and prevents
the exhaust HC from releasing outside the vehicle. After that,
the HC trap catalyst temperature rises and releases the
absorbed HC. The released HC is burnt out in the downstream
three-way catalyst.

This fuel system is designed with consideration for
global environment protection to ensure safety at a
collision, reduce weight, and improve reliability and
quality. This system has the following features:

• A quick-joint connector of a plastic tube is used
for the fuel high-pressure hoses in the engine
compartment to reduce the permeation of fuel
evaporative emission.

• The surface of underfloor fuel pipes is coated
with 1-mm thickness of plastic to improve resis

-

tance to corrosion and chipping.

• A returnless fuel system eliminates returned fuel
from the engine. The heat that fuel receives from
the engine is reduced, minimizing fuel tempera

­ture in the fuel tank and controlling the amount of
evaporated gas.
