2007 MERCEDES-BENZ CLK350 keyless

453 Practical hints
Towing the vehicle
Warning!G
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle. Adapt your driving accordingly.
iTo signal turns while being towed with the
hazard warning flasher in use, switch on the igni-
tion 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 warn-
ing flasher will operate again.
!When towing the vehicle with all wheels on
the ground, please note the following:
With the automatic central locking activated and
the SmartKey in starter switch position2, or
KEYLESS-GO* start/stop button in position2,
the vehicle doors lock if the left front wheel as
well as the right rear wheel are turning at vehicle
speeds of approx. 9 mph (15 km / h) or more.
To prevent the vehicle door locks from locking,
deactivate the automatic central locking
(
page 164).
Towing of the vehicle should only be done using
the properly installed towing eye bolt. Never at-
tach tow cable, tow rope or tow rod to the vehi-
cle chassis, frame or suspension parts.
iIf the battery is disconnected or discharged

the SmartKey will not turn in the starter
switch. For more information, see “Battery”
(
page 447) and “Jump starting”
(
page 450).

the gear selector lever will remain locked in
positionP. For information on manually un-
locking the transmission gear selector lever,
see (
page 412).

456 Practical hints
Fuses
The electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and sys-
tems secured by that fuse will stop operat-
ing.If a newly inserted fuse blows again, have
the cause determined and rectified by an
authorized Mercedes-Benz Center.
The following aids are available to help you
replace fuses.

Fuse chart
The fuse chart is located in the main
fuse box in the passenger compart-
ment (
page 457). The fuse chart ex-
plains the fuse allocation and fuse
amperages.

Spare fuses
Spare fuses are located in the vehicle
tool kit in the spare wheel well
(
page 404).

Fuse extractor
The fuse extractor is located in the
trunk underneath the trunk floor cover
(
page 405), or
CLK 63 AMG (
page 404).The electrical fuses are located in different
fuse boxes:

in the passenger compartment on the
driver’s side (
page 457)

on the driver’s side of the engine com-
partment (
page 457)

in the trunk (page 458)
Before replacing fuses:
Apply the parking brake (page 59).
Make sure the gear selector lever is set
to position P (
page 172).
Turn off all electrical consumers.
Turn off the engine (page 60).
Remove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO*:
Open the driver’s door.
Warning!G
Only use fuses approved by Mercedes-Benz
with the specified amperage for the system
in question and do not attempt to repair or
bridge a blown fuse. Using other than ap-
proved fuses or using repaired or bridged
fuses may cause an overload leading to a
fire, and/or cause damage to electrical
components and/or systems. Have the
cause determined and remedied by an
authorized Mercedes-Benz Center
iA blown fuse must be replaced by an appro-
priate spare fuse (recognizable by its color or the
fuse rating given on the fuse) of the amperage
recommended in the fuse chart.
Any Mercedes-Benz Center will be glad to advise
you on this subject.
