DOOR SPEAKER
NOTE: The parts with "*" are installed exclusively to
the vehicles with Rockford Fosgate
® premium sound
system.
For the front door speaker, two types of speakers, 16
cm paper cone speaker speakers> and PP (polypropylene) cone speaker
® premium sound system>, are
available. For the rear door speaker, two types of
speakers, 16 cm paper cone speaker 4 speakers, 6 speakers> and PP (polypropylene)
cone 2-way coaxial speaker -
ers (Rockford Fosgate® premium sound system)>,
are available. Compared to the paper cone speakers,
the PP (polypropylene) cone speakers can playback
crisper bass. The door opening of the vehicles with 9
speaker (Rockford Fosgate
® premium sound sys-
tem) is blocked by using the sheet metal cover and
the urethane integrated resin sheet (resin cover and
water proof film) to make the door into a speaker
box, thus improving the sound quality. As an advan
-
tage of the sheet metal cover, the rigidity of the areas
around the speaker has been increased, and the
higher sound pressure, suppression of high har
-
monic, and suppression of dumping are achieved to
improve sound quality.
The one-touch installable speaker (with 3 tabs, fixed
by rotating) has been adopted to improve service
-
ability.

GENERAL DESCRIPTION
HEATER, AIR CONDITIONING AND VENTILATION55-2
GENERAL DESCRIPTIONM2551001500040
The blower, heater, and evaporator have been inte-
grated 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 out-
side/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.
•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 pro-
file oil separator has been installed, thus enhanc-
ing 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 sea-
sons with moderate temperature.
•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.

CYLINDER HEAD
A cylinder head made of an aluminum alloy, which is
lightweight and offers a high level of cooling effi
-
ciency, has been adopted. A pentroof combustion
chamber with a center spark plug has been adopted.
It has a small valve compound angle to realize a
compact chamber.
Cross-flow type intake and exhaust ports have been
adopted. Two intake ports and two exhaust ports are
provided independently on the right and left sides.
Five camshaft bearings are provided at the intake
and exhaust sides, respectively. The No. 4 bearing
sustains the thrust load of the camshaft. Only the No.
1 bearing uses a bearing cap that integrates both the
intake and exhaust sides.
VA LV E S E AT S
Sintered alloy valve seats have been adopted.The oversized (0.3 mm) service parts are available.
VA LV E G U I D E S
Valve guides that are common to both the intake and
exhaust have been adopted.The oversized (0.25 mm) service parts are available.

AUTO-CRUISE CONTROL SYSTEM
ENGINE AND EMISSION CONTROL17-7
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
-
celled immediately.
•ECM abnormality
•TP sensor abnormality
•APP sensor abnormality
.
DIAGNOSIS FUNCTION
•The diagnostic trouble code check is possible
with the "CRUISE" indicator light.
•To facilitate the system check, check the service
data output with the M.U.T.-III.
