System Operation
Electric Booster Heater
In diesel vehicles which give off little residual heat,
a booster heater is used to heat the passenger
compartment rapidly in the case of low ambient
temperatures.
If the interior temperature has been set to HI, or if
the heater controls have been switched to the
highest setting, the two-zone air conditioning
system sends an "electric booster heater ON"
request signal to the CAN (controller area network)
via the medium speed GEM bus. If a manual air
conditioning system is installed, the signal is
transmitted via a conventional cable connection.
The GEM switches on the electric booster heater
depending on the following parameters:
• Engine coolant temperature is below 60 °C.
• Ambient air temperature is below 10 °C.
• Sufficient generator capacity is available.
The electric booster heater electronics activate
three output stages as a function of a pulse width
modulated signal PWM (pulse width modulation)
generated by the GEM. The output stages switch
the three heating elements of the electric booster
heater ON or OFF individually, whereby the heating
periods of the individual elements can overlap. Due
to the variable switch-on duration, continuously
variable temperature control is possible. The overall
heating power of the three heating elements is
linearly proportional to the PWM signal. If the PWM
signal is below 10% or above 95%, the electric
booster heater is not activated.
The electric booster heater is switched off when
an engine coolant temperature of 70°C or an
ambient air temperature of 20°C is exceeded.

6. NOTE: If any of the readings vary by morethan 0.015 mm or the brake disc thickness
is less than the specified minimum, a new
brake disc must be installed and the brake
disc runout re-checked.
Check the brake disc thickness variation.
For additional information, refer to:Specifications (206-00 Brake System -
General Information, Specifications).
• Using a suitable micrometer, measure the brake disc thickness at eight positions, 45
degrees apart and approximately 15 mm from
the outer edge of the brake disc.

7. If all the brake disc runout measurementsand the thickness variation are within the
specifications, check the wheel balance.
8. If just the brake disc runout measurement with the wheel and tire fitted exceeds the
specification, the wheel and tire must be
rotated through 90 degrees in relation to the
brake disc and the brake disc runout
re-checked.
• If the brake disc runout measurement still exceeds the specification, repeat the wheel and tire rotation and checking process until
the measurement is within specification.
9. If the brake disc runout measurement without the wheel and tire fitted is outside the
specification, check the wheel hub face
runout.
10. NOTE: Using paint or typing correction fluid, mark the position of the brake disc in
relation to the wheel hub.
Remove the brake disc.
11. NOTE: Make sure that the wheel hub face is clean and free of rust and foreign
material.
NOTE: Re-position the dial indicator gauge so that
it contacts the wheel hub approximately 10 mm
from the outer edge of the wheel hub.
Check the wheel hub face runout.• Slowly rotate the wheel hub and note the readings.

12. If the wheel hub runout exceeds 0.03 mm, install a new wheel hub.
For additional information, refer to: Wheel
Hub (204-01 Front Suspension, Removal
and Installation)
/ Wheel Bearing and Wheel Hub (204-02
Rear Suspension, Removal and
Installation).
13. If the wheel hub face runout is within specification, install a new brake disc.
