SUNROOF
M2420016000242
Electric sliding glass sunroof with tilt-up mechanism
has been adopted (Option). This sunroof features the
following characteristics.
•Lightweight sunroof have been adopted.
•The sunroof tilts up for approx. 30mm to improve
ventilation performance.
•The integrated switch allows for all slide
open/close, tilt up/down and stop operations.
•If external force is applied during slide closing or
tilt down operations that obstructs operations,
then the sunroof lid glass will stop according to
the jam prevention mechanism.

1.T u rn ON and hold the sunroo f switch un til t he
sunroo f moves in the desired d i rection and stop s.
2.If the sunroof does not move to the fully closed

p r even tion f unction op erat es again, release the
sunroo f switch. Th en within the elap se of 3
seco nds, turn ON and ho ld it again until th e
sunroo f stop s at the fully closed position.
If the sunroof does not o perate corre ctly even af ter

FEATURES
IMPROVEMENT OF VISUAL OBSERVA-
TION AND SAFETY, AND ENHANCEMENT
OF USER-FRIENDLINESS AND VERSA
-
TILITY
•The large four headlamps with the lightweight
resin lenses have been adopted.
•The high-mounted stop lamp has been installed
on the tailgate for all models.
•Combination meters and ECUs are connected
using CAN to ensure the transmission of informa
-
tion.
•The combination meters are provided integrated
with a perfect round-shaped speedometer where
the needles operate at the wider angle.
IMPROVEMENTS IN SERVICE QUALITY
•Diagnosis connector for inspection with M.U.T.-III
is installed.
•Diagnosis and service data are integrated in the
combination meter, enabling communication with
M.U.T.-III
BETTER PRODUCT PACKAGE
•The smart wiring system (SWS) has been
adopted for the lamp control including the head
-
lamp auto turn-off and fog lamp unattended-oper-
ation reminder.

COMBINATION METER
CHASSIS ELECTRICAL54A-10
COMBINATION METER
M2540005000894
The combination meter features large, clearly visible
analogue indicators. The meter has the speedometer
in the middle, the coolant temperature gauge at
upper right, the fuel gauge at lower right, and the
tachometer at left so that drivers can easily distin
-
guish the information from the meters. The combina-
tion meter offers the following advantages.
•The combination meter is used for air conditioner
and meter drive control to integrate ECU.
•CAN communication is used for more reliable
transmission of all gauge data and indicator lamp
input signals, such as vehicle speed, engine
RPM, and coolant temperature. For further
details on CAN, refer to GROUP 54C, CAN
P.54C-2. The signals that the combination meter
uses are described in the CAN communications
input signals table
.
•Several diagnosis functions such as the diagno-
sis code memory and actuator tests are prepared
in order to improve serviceability.
•For a brighter display at night and for a longer
useful life, all indicator lamps, warning lamps, and
illumination bulbs use LEDs.
•The indicators for the speedometer, fuel gauge,
and other gauges are driven by a stepping motor.
For further details, consult the stepping motor
section
.
•The electronic speedometer operates by receiv-
ing vehicle speed signals sent by the
engine-ECU or engine-CVT-ECU
via the CAN.
•A large and clear LCD type odo-tripmeter is pro-
vided. The odometer continuously displays val-
ues while the tripmeter adopts a twin-trip (trip A,
trip B) function which is switched by a reset but
-
ton. In addition, clock function is incorporated.
•A fog lamp indicator lamp is provided to let the
driver know that the fog lamp is on.
•A seat belt warning lamp is installed to encourage
the driver to fasten the seat belt.
•The high-contrast meter is adopted. When the
ignition is turned ON, such as the needles and
face display are illuminated with fade-in lighting
by the LED light source.
•To further accentuate the high-contrast lighting,
the light of the high-contrast meter fades in and
fades out when the light is turned on and off
respectively.
•With the auto illumination function incorporated in
the high-contrast meter, a two-stage switching of
daytime (non-dimming) and nighttime (dimming)
is achieved. Also, the brightness can be adjusted
using the illumination control knob.
•A tail lamp indicator lamp is installed which
informs the lighting status of the tail lamps to the
driver.

<4A9>
The newly-developed 4A9 engine has been installed
to realise small-size, light-weight, high-performance,
and better fuel economy with the state-of-the-art
technologies such as the aluminium die-cast cylinder
block, direct attack driven-type DOHC MIVEC, timing
chain-type cam drive, and rear exhaust.
