2003 MERCEDES-BENZ C320 4MATIC WAGON turn signal

311 Practical hints
Towing the vehicle
!To be certain to avoid a possibility of
damage to the drive train, however, we
recommend the drive shaft be discon-
nected at the rear axle drive flange
(vehicles with 4MATIC*: disconnected
at the front and rear axle drive flanges)
for any towing beyond a short tow to a
nearby garage.
Warning!
G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:

the engine will not run


there is a malfunction in the power
supply or in the vehicle’s electrical
system
as that will be necessary to adequately
control the towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make certain that the key is in
starter switch position2.
If the key is left in starter switch position0
for an extended period of time, it can no
longer be turned in the switch. In this case,
the steering is locked. To unlock, remove
key from starter switch and reinsert.
iTo signal turns while being towed with
the hazard warning flasher in use, turn
key in starter switch to position2 and
activate the combination switch for the
left or right turn signal in the usual
manner – only the selected turn signal
will operate.
Upon canceling the turn signal, the
hazard warning flasher will operate
again.
