VOICE GUIDANCE
VOICE RECOGNITION
An indirect route is suggested.If there are restrictions (such as one way streets)
on roads close to the starting point or destination,
the system may suggest an indirect route.Adjust the location of the starting point or
destination.
The system may suggest an indirect route because
route calculation does not take into consideration
some areas such as narrow streets (gray roads).Reset the destination to a main or ordinary
road, and recalculate the route.
The landmark information does not
correspond to the actual informa-
tion.This may caused by insufficient or incorrect data on
the DVD-ROM.This is not a malfunction.
The suggested route does not
exactly connect to the starting
point, waypoints, or destination.There is no data for route calculation closer to
these locations.Set the starting point, waypoints and desti-
nation on main road, and perform route cal-
culation. Symptom Possible cause Possible solution
Symptom Possible cause Possible solution
The voice guidance is not avail-
able.Voice guidance is only available at certain intersec-
tions. In some cases, voice guidance is not avail-
able even when the vehicle should make a turn.This is not a malfunction.
The vehicle has deviated from the suggested
route.Go back to the suggested route or request
route calculation again.
Voice guidance is set to off. Turn on the voice guidance.
Route guidance is set to off. Turn on the voice guidance.
The guidance content does not
correspond to the actual condition.The content of the voice guidance may vary,
depending on the types of intersections at which
turns are made.Follow all traffic rules and regulations.
Symptom Possible cause Possible solution
The system does not recognize
the command.
The system recognizes the com-
mand incorrectly.The interior of the vehicle is too noisy.Close the windows or have other occu-
pants be quiet.
The volume of the voice is too low. Speak louder.
Pronounceation is unclear. Speak clearly.
Voice recognition mode is not yet ready to speak.Push the release “PPT” on the steering
switch, and speak a command after the
tone sounds.
5 seconds or more have passed after pushed and
released “PTT” on the steering switch.Make sure to speak a command within 5
seconds after push and release “PTT” on
the steering switch.
Only a limited range of voice commands is usable
for each screen.Use a correct voice command appropriate
for the current screen.

CAN Communication System DescriptionEIS00D7T
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

lHolding the switch for more than 3 seconds resets all functions
(except trip A and DTE).
NOTE:
lAfter the display changes automatically, the indication can be
changed to the next mode by pressing the odo/trip meter switch.
lThe record of the odometer is kept even if the battery cable is disconnected.
TRIP COMPUTER
Function
The trip computer can indicate the following items.
lDTE (distance to empty)
lAverage fuel economy
lAverage vehicle speed
lRunning time
DTE (Distance to Empty) Indication
The DTE indication provides the driver with the distance estimation that can be driven before refueling. The
DTE is calculated by signals from the fuel level sensor unit (fuel remaining), ECM (fuel consumption) and ABS
actuator and electric unit (control unit) (vehicle speed). The indication is refreshed every 30 seconds. When
fuel remaining is less than approximately 11.6 (2 1/2 Imp gal), the indication blinks as a warning. If the fuel
remaining is less than approximately 9.6 (2 1/8 Imp gal), the indication shows “---”. In this case, the display
changes to the DTE mode from the different mode. When the battery cable is disconnected and reconnected,
DTE mode displays “---” until the vehicle is driven 0.5 km.
Average Vehicle Speed Indication
Average vehicle speed indication is calculated by running distance and running time. The indication is
refreshed every 30 seconds. If average vehicle speed is reset, average fuel consumption is reset at the same
time. At about 0.5 km and for 30 seconds after resetting, the display shows “- ”®“- ”®“-”®“ -”.
Average Fuel Economy Indication
Average fuel consumption indication is calculated by signals from ABS actuator and electric unit (vehicle
speed) and the ECM (fuel consumption). The indication is refreshed every 30 seconds. At about 0.5 km and
for 30 seconds after resetting, the display shows “- ”®“- ”®“-”®“ -”.
Running Time Indication
Trip time displays ignition switch ON time cumulatively. If trip time is reset, trip distance is reset at the same
time.

Fuel Injection Control SystemEBS01KCE
SYSTEM DESCRIPTION
Three types of fuel injection control are provided to accommodate engine operating conditions; normal control,
idle control and start control. The ECM determines the appropriate fuel injection control. Under each control,
the amount of fuel injected is adjusted to improve engine performance.
Pulse signals are sent to fuel injectors according to the input signals to adjust the amount of fuel injected to
preset value.

EC
When the ECM receives a start signal from the ignition switch, the
ECM adapts the fuel injection system for the start control. The
amount of fuel injected at engine starting is a preset program value
in the ECM. The program is determined by the engine speed, engine
coolant temperature and fuel rail pressure.
For better startability under cool engine conditions, the lower the
coolant temperature becomes, the greater the amount of fuel
injected. The ECM ends the start control when the engine speed
reaches the specific value, and shifts the control to the normal or idle
control.
IDLE CONTROL
Input/Output Signal Chart
*: The input signal is sent to the ECM through CAN communication line.
When the ECM determines that the engine speed is at idle, the fuel injection system is adapted for the idle
control. The ECM regulates the amount of fuel injected corresponding to changes in load applied to the engine
to keep engine speed constant. The ECM also provides the system with a fast idle control in response to the
engine coolant temperature signal.
NORMAL CONTROL
Input/Output Signal Chart
The amount of fuel injected under normal driving conditions is deter-
mined according to sensor signals. The crankshaft position sensor
detects engine speed, the accelerator pedal position sensor detects
accelerator pedal position and fuel rail pressure sensor detects fuel
rail pressure. These sensors send signals to the ECM.
The fuel injection data, predetermined by correlation between vari-
ous engine speeds, accelerator pedal positions and fuel rail pres-
sure are stored in the ECM memory, forming a map. The ECM
determines the optimal amount of fuel to be injected using the sen-
sor signals in comparison with the map.
