ation depending on the outside
temperature.

endangering you and others.!The rear window defroster cannot be
switched on when the retractable hard-
top is open. The indicator lamp will
start blinking if the hardtop is open.
Close the retractable hardtop.
The rear window defroster can again be

!If the rear window defroster switches
off too soon and the indicator lamp
starts blinking, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system
responds automatically by deactivating
the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster au-
tomatically turns itself back on.

Retractable hardtop
Indicator lamp in the retractable hard-
top switch lights when vehicle is
stopped
If the indicator lamp in the retractable
hardtop switch lights while the vehicle is
standing still and the switch was not acti-
vated, then the retractable hardtop is not
locked.
Properly lock the retractable hardtop
(page 162) before continuing to
drive.
The retractable hardtop will not lock
There is a malfunction in the retractable
hardtop system.
Notify an authorized Mercedes-Benz
Center.Wind screen
The wind screen deflects drafts away from
the driver and passenger when the hardtop
is lowered. It is stored in a separate stor-
age bag.
Installing
Leave the wind screen folded and place
it on the roll bar.1Guide tabs
Slide the wind screen into the roll bar
until the guide taps on each side latch
underneath the roll bar. Make sure that
the fastening straps do not get caught.
Raise the roll bar slightly (
page 61).
Warning!
G
The wind screen can restrict the driver’s vi-
sion to the rear of the vehicle. To prevent a
possible accident when visibility is limited
(e.g. in darkness), the upper part of the wind
screen should be folded back.

237 Operation
Tires and wheels
Activating the tire inflation pressure
monitor
You must activate the tire inflation pres-
sure monitor in the following cases:
if you have changed the tire pressure
if you have replaced the wheels or tires
if you have installed new wheels or
tires
Be sure that the tire pressure is cor-
rectly set.
Press the
k
button until the infla-
tion pressure of each tire appears in
the right display field.
Press the reset knob (
page 21).
The following message will appear in
the speedometer display field:
Monitor current tire pressure?
Press
æ
button.
The following message will appear in
the speedometer display field:
Tire pressure monitor activated!
Pressure display after driving
several mins.
Warning!
G
Follow recommend tire 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.iOperating radio transmission equip-
ment (e.g. wireless headsets, two-way
radios) in or near the vehicle could
cause the tire inflation pressure moni-
tor to malfunction.
iIf transporting a deflated road wheel or
additional wheel sensors in the vehicle,
the tire inflation pressure monitor
should not be reactivated until the de-
flated wheel or additional wheel sen-
sors have been removed from the
vehicle. Otherwise, the deflated wheel
or additional sensors could confuse the
tire inflation pressure monitor system
and cause it to malfunction.
