Give very little gas.

Have the problem repaired by an au-
thorized Mercedes-Benz Center as
soon as possible.The coolant temperature is
above 248°F (120°C)
The coolant is too hot and is no longer

71 Safety and Security
Occupant safety
Roll bars
The roll bars are integrated into the rear
head restraints.
The roll bars raise automatically in an acci-
dent or in a critical driving situation.You can manually lower the roll bars again
when the soft top is open (
page 402).
With the soft top closed, contact an autho-
rized Mercedes-Benz Center to have the
roll bars lowered. Do not attempt to lower
the roll bars manually with the soft top
closed. Lowering the roll bars manually
with the soft top closed may impair the
function of the roll bars.
Warning!
G
Make sure nothing is blocking the roll bars’
path of motion. Otherwise someone could
be injured when the roll bars are raised. The
head restraints should therefore always be
in the raised position when the rear seat is
occupied (
page 115).
iWhen the roll bars are raised automati-
cally, you will hear a ratcheting sound
and the rear head restraints will also
rise.
iYou cannot lower the rear head
restraints with the rear head restraint
lowering switch (
page 115) when the
roll bars are in the raised position.
Also, you cannot operate the soft top
using the soft top switch when the roll
bars are in the raised position.


If the soft top is open, you can man-
ually lower the roll bars
(page 402).


If the soft top is closed, contact an
authorized Mercedes-Benz Center
to have the roll bars lowered.
Warning!
G
If the yellow roll bar warning lamp in
the clock does not go out after starting the
engine, or if it comes on while driving, then
the roll bar system is not operating properly
and may not activate in an accident. In this
case, raise the roll bars manually before
continuing to drive (
page 401).
For safety reasons, drive only with the roll
bars raised until the malfunction is repaired.
Have your vehicle checked at an authorized
Mercedes-Benz Center.
