longer brake your vehicle and it could roll
away.

There is a risk of an accident and injury.
Therefore, quickly move your foot from the

Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible.
Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.

Hood
Opening the hood G
WARNING
Do not pull the release lever while the vehicle
is in motion. Otherwise, the hood could be
forced open by passing air flow.
This

could cause the hood to come loose and
injure you and/or others. G
WARNING
Do not open the hood when the engine is
overheated. You could be seriously injured.
Observe the coolant temperature gauge to
determine whether the engine may be
overheated. If you see flames or smoke
coming from the engine compartment, move
away from the vehicle. Wait until the engine
has cooled. If necessary, call the fire
department. G
WARNING
There is a risk of injury if the hood is open,
even if the engine is not running.
Some engine components can become very
hot.
To avoid the risk of burns, only touch those
components described in the Operator's
Manual

and observe the relevant safety notes. G
WARNING
To avoid injury, stay clear of moving parts
when the hood is open and the engine is
running.
The radiator fan may continue to run for
approximately 30seconds

or may even restart
after the engine has been switched off. For
this reason, you must not reach into the fan
rotation area. G
WARNING
The engine is equipped with a transistorized
ignition system. Because of the high voltage,
it is dangerous to touch any components
(ignition coils, spark plug sockets, diagnostic
socket) of the ignition system:
R with the engine running
R while starting the engine
R when the ignition is switched on and the
engine is turned manually G
WARNING
The windshield wipers and wiper linkage
could be set in motion.
When the hood is open, you or others could
be injured by the wiper linkage.
Make sure that the windshield wipers are
switched off. Remove the SmartKey or make
sure that no ignition position has been
selected with KEYLESS-GO. All indicator
lamps must be off in the instrument panel.
! Make

sure that the windshield wipers are
not folded away from the windshield. You
could otherwise damage the windshield
wipers or the hood. 294

Maintenance and care

R
using a rag, slowly turn the cap
approximately 1
/ 2 turn to relieve excess
pressure. If opened immediately, scalding
hot
fluid and steam will be blown out under
pressure.
R do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which
may burn if it comes into contact with hot
engine parts. X
Park the vehicle on a level surface.
Only check the coolant level when the
vehicle

is on a level surface and the engine
has cooled down.
X Turn the SmartKey to position 2 in the
ignition lock ( Y page 151).
On vehicles with KEYLESS-GO, press the
Start/Stop button twice

(Y page 151).
X Check the coolant temperature display in
the instrument cluster.
The coolant temperature must be below
158 ‡

(70 †).
X Turn the SmartKey to position
0 (Y page 151) in the ignition lock.
X Slowly turn cap : half a turn counter-
clockwise to allow excess pressure to
escape.
X Turn cap :
further counter-clockwise and
remove it.
If the coolant is at the level of marker bar
= in the filler neck when cold, there is
enough coolant in coolant expansion
tank ;.
If the coolant level is approximately 0.6 in
(1.5 cm) above marker bar = in the fillerneck when warm, there is enough coolant
in coolant expansion tank
;.
X If necessary, add coolant that has been
tested and approved by Mercedes-Benz.
X Replace cap :
and turn it clockwise as far
as it will go.
For further information on coolant, see
(Y page 366).

Maintenance and care Z

Cleaning the vehicle parts
Cleaning the Cabriolet soft top !
Never use any of the following to clean the
soft top:
R gasoline
R thinner
R tar or stain remover
R other organic solvents
! Remove bird droppings immediately as
they are corrosive and, therefore, can make
the soft-top fabric leak. Do not use high-
pressure cleaning equipment to clean the
vehicle. Do not use sharp-edged equipment
to remove ice and snow.
X Light soiling: you can clean the soft top
while it is dry or rinse it with clear water.
X Normal to heavy soiling: clean the soft
top with a brush and clear water. Clean
stains and other dirt with a brush and soft
top cleaning agents that have been
recommended

and approved by Mercedes-
Benz. Always brush from front to back,
following the grain of the fabric.
Frequent cleaning reduces the soft top's
resistance to dirt.
To restore this resistance to dirt, clean the
soft top using soft top cleaning agents that
have been recommended and approved by
Mercedes-Benz.
Incorrect

cleaning and care, as well as aging,
can cause the soft-top seams to leak. Have
the soft-top seams sealed at a qualified
specialist workshop, e.g. at an authorized
Mercedes-Benz Center.
i Cover the soft top appropriately if you
plan to leave the vehicle outside for a long
period of time. Cleaning AIRCAP Cleaning the wind deflector
!
Do not use high-pressure cleaning
equipment to clean the net.
Clean the wind deflector on the windshield
with the soft top closed.
X Apply the parking brake firmly.
X Vehicles with SmartKey: turn the
SmartKey to position 2 in the ignition lock
(Y page 151).
X Vehicles with KEYLESS-GO: press the
Start/Stop button twice
(Y page 151).
X Open the cover in the lower center console.
The AIRCAP button is under the cover. X
Press AIRCAP button :.
The
wind deflector between the windshield
and the soft top is extended. X
Clean net ; of the wind deflector with a
soft brush or a moist cloth. For heavier
soiling, clean it with the care and cleaning
agents recommended and approved by302
Care
Maintenance and care

Mercedes-Benz and rinse it with clean
water.
Cleaning the AIRCAP wind screen
Clean the AIRCAP wind screen with the soft
top open.
X Vehicles with SmartKey: turn the
SmartKey to position 2 in the ignition lock
(Y page 151).
X Vehicles with KEYLESS-GO: press the
Start/Stop button twice (Y page 151).
X Open the soft top (Y page 90). X
Press rear seat head restraints button :.
The rear seat head restraints and AIRCAP
wind screen rise upwards. X
Clean net ; of the AIRCAP wind screen
with a moist cloth together with the care
and cleaning agents recommended and
approved by Mercedes-Benz. Cleaning the wheels !
Do
not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after
cleaning. Braking heats the brake discs and
the brake pads/linings, thus drying them.
The vehicle can then be parked.
Cleaning the windows G
WARNING
Before cleaning the windshield or wiper
blades, switch off the windshield wipers and
remove the SmartKey from the ignition lock.
On vehicles with KEYLESS-GO, press the
Start/Stop button repeatedly until all
indicator

lamps in the instrument cluster have
gone out. The windshield wipers could
otherwise move and injure you.
! Do not use dry cloths, abrasive products,
solvents or cleaning agents containing
solvents to clean the inside of the windows.
Do not touch the insides of the windows
with hard objects, e.g. an ice scraper or
ring. There is otherwise a risk of damaging
the windows.
! Clean the water drainage channels of the
windshield and the rear window at regular
intervals. Deposits such as leaves, petals
and pollen may under certain
circumstances prevent water from draining
away. This can lead to corrosion damage
and damage to electronic components.
X Clean the inside and outside of the
windows with a damp cloth and a cleaning
agent that is recommended and approved
by Mercedes-Benz. Care
