Opening/closing in an emergency
Opening/closing in an emergency
Raising retractable hardtop manually
If the retractable hardtop cannot be closed
automatically, make certain that all points
listed under the “Retractable hardtop” sec-
tion (
page 130) were observed.
If the automatic operation still does not
function properly, you can close the re-
tractable hardtop manually.
This procedure should be performed with
great care by two persons.

Open doors or lower windows
(page 128).

Set parking brake (
page 47).

Remove key from steering lock
(page 29).

Open trunk lid (
page 78).

Remove CD changer (
page 122).

Open the right side trim panel in the
trunk. Remove cover, if necessary.
!Manually closing the retractable hard-
top is a complicated and technically de-
manding procedure. Close the
retractable hardtop manually in emer-
gency cases only. Otherwise, visit an
authorized Mercedes-Benz Center.
Warning!
G


It is important that a second person
helps you. Otherwise, you could become
trapped or injured.


Remove any wristwatches or jewelry
such as rings or bracelets. Otherwise,
they could get caught in the vehicle
mechanism, causing personal injury to
yourself or damage to the vehicle.


Always use the grips provided. Other-
wise you could injure yourself.
iIf your CD changer holder does not
have the fasteners 1 as shown under
“Installing and removing the CD chang-
er*” (
page 122), your vehicle may be
equipped with a non-factory installed
CD changer holder. The holder then
does not need to be removed as there
should be enough room between the
CD changer holder and the right side
trim panel in the trunk to remove the
cover and gain access to the screw for
hydraulic pump should you need to
raise the retractable hardtop manually.


250 Practical hintsFlat tire

Detach the electric air pump.

Reinstall tire valve cap.

Stow the electrical plug and the air
hose behind the flap and place the air
pump back in the trunk.

Close the trunk lid.Storing collapsible spare wheel in
wheel well
Before you can store the spare wheel with
collapsible tire in the wheel well you have
to release the air pressure of the tire.

Unscrew valve stem removal tool,
which is part of the valve cap, from tire
valve.

Using the valve stem removal tool,
open tire valve slightly by turning the
tire valve insert counterclockwise to
release air pressure.

When the air pressure has been re-
leased, remove tire valve insert (pro-
tect it from dirt and sand) using the
previously removed tire valve cap.

Once all air is out of the tire, and the
tire has collapsed to its original shape,
reinstall the tire valve insert and valve
cap.

Place spare wheel in wheel well and
secure it with the pump holder.

Turn pump holder clockwise to its stop.
Warning!
G
Follow recommended inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the pillar in the driver’s
door opening). Overloading the tires can
overheat them, possibly causing a blowout.
Warning!
G
To prevent possible injury when unscrewing
air pump filler hose from tire valve after in-
flating the tire, use a rag since the tire valve
could be hot.


257 Practical hints
Towing the vehicle
Warning!
G
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 position 0
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.
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 sup-
ply or in the vehicle’s electrical system
as that will be necessary to adequately con-
trol the towed 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, 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 haz-
ard warning flasher will operate again.
!When towing the vehicle with all wheels
on the ground, please note the follow-
ing:
With the automatic central locking acti-
vated and the key in starter switch
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.
Switch off the tow-away alarm
(page 72).
To prevent the vehicle door locks from
locking, deactivate the automatic cen-
tral locking (
page 79).
Towing of the vehicle should only be
done using the properly installed tow-
ing eye bolt. Never attach tow cable,
tow rope or tow rod to the vehicle chas-
sis, frame or suspension parts.
