Generator
General information
The powertrain control module (PCM) controls the
alternator charging voltage. The connection
between the PCM and the generator is made via
the control module subnetwork (LIN) bus.
If the load on the alternator is high, the PCM can
increase the idle speed.
The alternator is temporarily deactivated during
engine starting so that the engine drag moment is
minimized and it is reactivated again after the
starting procedure.
The PCM controls the charge control lamp in the
instrument cluster via the controller area network
(CAN) bus.
Smart Charge system
In addition to the familiar functions, the Smart
Charge system also performs the following
functions:
•
Automatic deactivation of non-critical high power
electrical consumers when the battery voltage
is low in order to reduce the level of current
drawn.
• Automatic activation of non-critical high power electrical consumers when the battery voltage
is excessively high in order to protect
components which are sensitive to increased
voltages.
The battery charging current is optimized through
continuous calculation of the battery temperature
and monitoring of the alternator output voltage.
By receiving the forwarded alternator load signal,
the PCM is given early warning whenever an
electric consumer is switched on or off. This means
that the PCM receives information about imminent
changes in the torque drawn by the alternator. By
evaluating this information the PCM can provide a
higher level of idling stability.
The two remaining functions of the Smart Charge
System are controlled by the GEM.
Electrical consumers are switched off due to low
voltage when the GEM determines (on the basis
of the message received from the PCM on the CAN
bus via the instrument cluster) that the battery
voltage has dropped below the threshold.
When the threshold for low battery voltage is
reached the GEM automatically deactivates the following consumers - in this order and with a gap
of 5 seconds between each:
• Electric booster heater (vehicles with diesel
engines)
• Heated exterior mirrors
• Heated rear window
• Heated windscreen
If the battery voltage rises back above the lower
threshold then the GEM re-enables all of the
electrical consumers which were previously
disabled. They then have switched off status and
must be switched back on by the driver.
Electrical consumers are switched on due to
excessively high voltage if the GEM determines
that the battery voltage is above the threshold for
overvoltage and the charge control lamp has been
switched on.
When the threshold is reached the GEM
automatically activates the following consumers -
in this order and with a gap of 5 seconds between
each:
• Heated rear window
• Heated exterior mirrors
• Electric booster heater (vehicles with diesel engines)
• Blower motor
If the battery voltage drops back below the
threshold then the GEM automatically deactivates
any consumers that were switched on. However,
if they were switched on by the driver before the
automatic activation, they will then be switched on
again in turn with a 5-second time interval. G964174en

Combined rain sensor/light sensor
CAUTIONS:
On vehicles with autolamps, retrofitting
with daytime running lamps is not
permissible, as otherwise, the engine
cannot be stopped when the lighting is
switched on.
On vehicles with autolamps, the daytime
running lamp fuse must not be fitted, as
otherwise, the engine cannot be stopped
when the lighting is switched on.
The combined rain sensor/light sensor is located
behind the interior rear view mirror.
autolamps The low beams, side lamps, license plate lamps
as well as the instrument cluster and instrument
panel illumination are switched on automatically if
all the following conditions are met:
• Ignition ON
• Light switch in the "AUTO" position
•
Detected ambient light conditions below a stored
threshold value
These are switched on and off by the GEM (generic
electronic module) in accordance with the input
signals from the combined rain/light sensor.
Headlamp switch-off delay
In vehicles with mid to high-end equipment, the
headlamp switch-off delay uses the dipped beam
headlamps and the door entry illumination (if
equipped) to illuminate the vehicle surroundings.
This function is activated by operating the main
beam headlamp lever with the ignition switched
off. After the last door has been closed, the function
remains active for a further 30 seconds and then
switches off automatically.
When a door or the tailgate is open, the switch-off
time is extended to 180 seconds. After the last door
has been closed, the switch-off time is reset to 30
seconds.
The headlamp switch-off delay can be deactivated
prematurely by operating the high beam lever again
or by switching on the ignition.
The switch-off time is adjusted to fixed values at
the factory and can
notbe re-programmed using
WDS.
Turn signals The turn signals and the warning lamp flash at a
specified frequency and, in the case of failure of a
turn signal, the frequency is doubled.
The turn signal lamps also have a one-touch lane
change function. If the multifunction lever is
pressed just slightly then the relevant turn signal
lamp is actuated 3 times.

• 4 minutes have elapsed since the button for the
heated windshield was pressed.
• The ignition switch is turned to the "I" or "0" position.
• The "Defrost" function is deactivated or the switch for the heated windscreen is pressed
again while the heated windscreen is still
switched on.
• The charging system warning indicator is switched on.
• The battery voltage falls below the threshold value for low battery voltage for more than 20
seconds (power management strategy). Manual
requests for switching on the heated windshield
by pressing the switch are ignored at this time.
• More than 4 minutes have passed since starting
the engine.
Heated rear window and heated external
mirrors
The GEM transmits a request signal via the CAN
bus to the door modules to switch on the heated
exterior mirrors.
The heated rear window and the heated exterior
mirrors are switched on by the GEM under the
following conditions:
• The switch for the heated rear window is pressed and the ignition switch is in the "II"
position.
• The "defrost" function of the air conditioning is activated and the ignition switch is in the position
"II".
• The battery voltage has exceeded 16 V for more
than 20 seconds (power management strategy).
Manual requests to switch off the heated rear
window by pressing the button are ignored at
this time.
• The engine was started at an outside air temperature below 4°C and an engine
temperature below 65°. Manual requests for
switching off the heated rear window by pressing
the switch are accepted.
NOTE: If the battery voltage returns to the normal
range then the disabling of the heated rear window
is cancelled - the heated rear window is then in a
switched-off state.
The GEM transmits a request signal via the CAN
bus to the door modules to switch off the heated
exterior mirrors. The heated rear window and the heated exterior
mirrors are switched off by the GEM under the
following conditions
• 14 minutes have elapsed since the button for
the heated rear window was pressed.
• The ignition switch is turned to the position "0", "I" or "III".
• The switch for the heated rear window is pressed or the "defrost" function of the air
conditioning is deactivated while the heated rear
window is switched on.
• The battery voltage has dropped below 10.3 V for more than 20 seconds (power management
strategy). Manual requests for switching on the
heated rear window by pressing the switch are
ignored at this time.
• More than 14 minutes have passed since starting the engine.
Ambient air temperature
The ambient air temperature sensor is connected
via a cable to the GEM. It measures the outside
air temperature to an accuracy of around ±0.5 °C.
The GEM broadcasts the ambient air temperature
on the medium speed CAN bus, where it can be
evaluated by various systems.
Brake fluid level
The brake fluid level switch is connected via a
cable to the GEM.
The GEM transmits a message on the medium
speed CAN bus. The instrument cluster then
transfers this message to the high speed CAN bus
where it is made available for various other
functions.
