System DescriptionNJEL0456WIPER OPERATIONNJEL0456S01The wiper switch is controlled by a lever built into the combination switch.
There are three wiper switch positions:
LO speed
HI speed
INT (Intermittent)
With the ignition switch in the ON or START position, power is supplied
through 20A fuse [No. 25, located in the fuse block (J/B)]
to front wiper motor terminal 5.
Low and High Speed Wiper OperationNJEL0456S0101Ground is supplied to wiper and washer switch terminal 17 through body grounds E30 and E73.
When the wiper switch is placed in the LO position, ground is supplied
through terminal 14 of the front wiper and washer switch
to front wiper motor terminal 2.
With power and ground supplied, the wiper motor operates at low speed.
When the wiper switch is placed in the HI position, ground is supplied
through terminal 16 of the front wiper and washer switch
to wiper motor terminal 1.
With power and ground supplied, the wiper motor operates at high speed.
Auto Stop OperationNJEL0456S0102With wiper switch turned OFF, wiper motor will continue to operate until wiper arms reach windshield base.
When wiper arms are not located at base of windshield with wiper switch OFF,ground is provided
from terminal 14 of the front wiper and washer switch
to front wiper motor terminal 2, in order to continue wiper motor operationat low speed.
Ground is also supplied
through terminal 13 of the front wiper and washer switch
to front wiper motor terminal 4
through terminal 3 of front wiper motor
through body grounds E30 and E73.
When wiper arms reach base of windshield, front wiper motor terminals 4 and5 are connected instead of ter-
minals 4 and 3. Wiper motor will then stop wiper arms at the STOP position.
Intermittent OperationNJEL0456S0103The front wiper motor operates the wiper arms one time at low speed at a set interval of approximately 1 to
13 seconds. This feature is controlled by the wiper amplifier (INT SW) combined with front wiper switch.
When the wiper switch is placed in the INT position, ground is supplied to wiper amplifier (WIPER SW INT)
and (ACC).
The desired interval time is input to wiper amplifier (INT VR) from wiper volume switch combined with front
wiper and washer switch.
When the wiper switch is placed in the INT position, intermittent ground issupplied
through wiper amplifier (OUTPUT) and
through terminal 14 of front wiper and washer switch
to front wiper motor terminal 5.
The wiper motor operates at low speed at the desired interval.
When the lever is pulled to the WASH position for one second or more, the wiper motor operates at low speed
for approximately 3 seconds to clean windshield. This feature is controlled by the wiper amplifier in the same
manner as the intermittent operation.
WASHER OPERATIONNJEL0456S02With the ignition switch in the ON or START position, power is supplied
through 10A fuse [No. 27, located in the fuse block (J/B)]
through front wiper switch terminals 15 and 18.
to front washer motor terminal 1.

SPEED DEPENDENT VOLUME CONTROLNJEL0497S13DescriptionNJEL0497S1301If activated, the radio output volume will be automatically adjusted to compensate for increased driving noises
at higher driving speeds.
The radio receives a speed signal from the combination meter and selects the output volume.
PERSONAL AUDIO SETTINGSNJEL0497S14DescriptionNJEL0497S1401The radio is designed to store several settings (volume, bass, treble, preset stations and level of speed
dependent volume control) with every NATS ignition key used. Up to a maximum of 4 NATS keys can be reg-
istered. During the communication mentioned under “Anti-Theft System”,the radio will recognize the used
ignition key and select the accompanying settings.

Range (km or MILES) Displays range to empty with a range of 000.0 to 999.9.
Journey distance (km or MILES) Displays journey distance with a range of 000.0 to 9999
Journey time Displays journey time with a range of 0000:00:00 to 9999:59:59.
Average fuel consumption (/100 km or
MPG)Displays fuel consumption with a range of 00.0 to 999.
Average vehicle speed (km/h or MPH) Displays average vehicle speed with a range of 000 to 999.
RangeNJEL0555S0401The elapsed time indication provides driver with an estimation
of the distance that can be driven before refuelling.The range
is conducted by fuel tank level sensor unit (fuel remaining),
ECM pulse signal (fuel consumption) and vehicle speed signal.
Indication will be renewed every 30 seconds.
When fuel remaining is less than approx. 7.8(6-7/8 Imp qt),
indication will blink as a warning. If the fuel remaining less than
approx. 6.8(6 Imp qt), “– –.–” will be indicated. In this case,
the mode will change to the RANGE mode automatically even
though the display is showing a different item. (See NOTE.)
The range mode includes a low range warning feature: when
the fuel level is low, the range mode is automatically selected
and the digits blink in order to draw the driver′s attention. Press
the “INFO” switch if you wish to return to the mode that was
selected before the warning occurred. The range mark will
remain blinking until next refuelling. When the fuel level drops
even lower, the range display will change to “– – – –”.
Journey DistanceNJEL0555S0402Journey distance indication is conducted by vehicle speed sig-
nal.
If journey distance is reset, journey time will be reset at the
same time.
When pushing “INFO” switch more than approximately 1
second, driving distance will be reset.
Journey TimeNJEL0555S0403Journey time indication is conducted by integration of ignition
ON time.
If journey time is reset, journey distance will be reset at the
same time.
Average Fuel ConsumptionNJEL0555S0404Average fuel consumption indication is conducted by ECM
pulse signal and vehicle speed signal after system is reset.
Indication will be renewed every 30 seconds.

When pushing “INFO” switch more than approximately 1
second, average fuel economy will be reset.
If average fuel consumption is reset, average vehicle speed
will be reset at the same time.
After reset operation, the display shows “– –. –” until the
vehicle is driven 500 m (1,600 ft) or 30 seconds has passed.
Average Vehicle SpeedNJEL0555S0405Average vehicle speed indication is conducted by running dis-
tance and running time.
Indication will be renewed every 30 seconds.
When pushing “INFO” switch more than approximately 1
second, average speed will be reset.
If average vehicle speed is reset, average fuel consumption
will be reset at the same time.
After reset operation, the displays shows “– –.–” for 30 sec-
onds.
HOW TO CHANGE/RESET INDICATIONNJEL0555S05Indication can be changed by in following order by pushing “INFO”
switch less than approximately 1 second.

AGE FUEL CONSUMPTION,AVERAGE VEHICLE SPEED
Continuous pushing the “INFO” switch (more than 3 second)
can reset the indication of journey distance (trip), journey time
(hour meter), average fuel consumption and average vehicle
speed.
NOTE:
After the display changes automatically, the indication can be
changed to the last mode by pushing the switch. In this case, the
cursor will blink as a warning.
