316 Operation
Engine compartment
The hood lock release lever is located to
the left of the steering wheel under the
dashboard.
1Hood lock release lever
Pull lever 1 downwards.
The hood is unlocked.2Lever for opening the hood
Push lever 2 on the hood upwards.
Pull up on the hood and then release it.
The hood will be automatically held
open at shoulder height by gas-filled
struts.Closing
Let the hood drop from a height of
approximately 1 ft (30 cm).
The hood will lock audibly.
Check to make sure the hood is fully
closed.
If you can raise the hood at a point
above the headlamps, then it is not
properly closed. Open it again and let it
drop with somewhat greater force.
!To avoid damage to the windshield wipers or
hood, never open the hood if the wiper arms are
folded forward away from the windshield.
Warning!G
When closing the hood, use extreme caution
not to catch hands or fingers.
Be careful that you do not close the hood on
anyone.
Make sure that the hood is securely en-
gaged before driving off. Do not continue
driving if the hood can no longer engage af-
ter an accident, for example. The hood could
otherwise come loose while the vehicle is in
motion and injure you and/or others.

359 Operation
Vehicle care
Soft top
Frequent cleaning reduces the
dirt-repellent effect of the soft top.
Intensive cleaning with Mercedes-Benz
car-care products for convertible soft tops
can help to restore the dirt-repellent
effect. Contact an authorized
Mercedes-Benz Center for detailed
information.
Light colored soft tops should be cleaned
frequently to prevent spots and dirt from
setting in, which could stain and discolor
the soft top material permanently.
Incorrect cleaning and care, as well as
ageing, can cause the soft-top seams to
leak. Have the soft-top seams sealed at a
Mercedes-Benz Center.Clean soft top with soft top raised and
locked. Lower the soft top into the storage
compartment only if the soft top is
completely dry.
Dry cleaning:
Brush the dry top with a soft-bristled
brush.
Brush top always from front to rear.
!Make sure that the windshield wiper switch
is set to0 (
page 55). Otherwise, e.g. the rain
sensor could activate and cause the wipers to
move unintentionally. This may lead to vehicle
damage.
Due to the width of the vehicle, fold in exterior
rear view mirrors prior to running the vehicle
through an automatic car wash to prevent
damage to the mirrors.
iAfter running the vehicle through an
automatic car wash, wipe any wax off of the
windshield (
page 362). This will prevent
smears and reduce wiping noise which can be
caused by residual wax on the windshield.
When leaving the car wash, make sure that the
mirrors are folded out. Otherwise they may
vibrate.
iIf the soft top is kept in the storage
compartment for a lengthy period, raise it and air
out with the windows open about every
4months.
Place a suitable cover over the soft top if you are
leaving the vehicle parked in the open for an
extended period of time.
!Remove bird droppings immediately. The
organic acid damages the material and causes
the soft top to leak.
Never use a power washer to clean the soft top,
as you may damage the soft top material.
Do not use sharp-edged instruments for the
removal of ice and snow.
Never use hot-wax when you run the vehicle
through an automatic car wash, as you may
damage the soft top material.
iDepending on the operation mode of the car
wash, there is the possibility of water drops
entering the vehicle’s interior. This is not an
indication of a defect or malfunction in
the soft top.

362 Operation
Vehicle care
Cleaning the windows and the wiper
blades
Make sure the hood is fully closed.
Make sure the vehicle’s on-board
electronics have status0 (
page 36).
Fold the wiper arms forward until they
snap into place.
Clean the wiper blade inserts with a
clean cloth and detergent solution.
Use a soft, clean cloth and a mild
window cleaning solution on all outside
and inside glass surfaces.
An automotive glass cleaner is
recommended.Light alloy wheels
If possible, clean wheels once a week.Use Mercedes-Benz approved Wheel
Care, a soft bristle brush and a strong
spray of water for cleaning the light
alloy wheels.!Never open the hood when the wiper arms
are folded forward.
Warning!G
For safety reasons, switch off wipers and
remove SmartKey from starter switch
(vehicles with KEYLESS-GO*: Make sure the
vehicle's on-board electronics have
status0) before cleaning the windshield
and/or the wiper blades. Otherwise, the
wiper motor could suddenly turn on and
cause injury.
!Do not pull on the wiper blade inserts. They
could tear.
!Fold the windshield wiper arms back onto
the windshield before turning the SmartKey in
the starter switch or pressing the KEYLESS-GO
start/stop button (vehicles with KEYLESS-GO*).
Hold on to the wiper when folding the wiper arm
back. If released, the force of the impact from
the tensioning spring could crack the windshield.
!To clean the window interior, do not use a
dry cloth, abrasives, solvents or cleaners
containing solvents. Do not touch the inside of
the front, rear or side windows with hard objects
such as an ice scraper or ring. Doing so may
damage the windows.
!Only use acid-free cleaning materials. Acid
may cause corrosion or damage the clear coat.
!The vehicle should not be parked for an
extended period of time immediately after it has
been cleaned, especially not after the wheel rims
have been cleaned with wheel rim cleaner.
Wheel rim cleaners can lead to increased
corrosion of the brake disks and brake pads.
Non-approved wheel cleaners may also damage
the wheel paint if the car is not driven after
cleaning. Therefore, the vehicle’s brake system
should always be warmed-up before it is parked
after cleaning. To do so, please drive your vehicle
for several minutes to allow the brakes to dry.
When applying Mercedes-Benz approved Tire
Care and Mercedes-Benz approved Wheel Care
products, take care not to spray them on the
brake disks.

remove SmartKey from starter switch
(vehicles with KEYLESS-GO*: make sure the
vehicle’s on-board electronics have
status0) before replacing a wiper blade.
Otherwise, the wiper motor could suddenly
turn on and cause injury.
Warning!G
Wiper blades are components that are sub-
ject to wear and tear. Change the wiper
blades twice a year, preferably in the spring
and fall. Otherwise the windows will not be
properly wiped. As a result, you may not be
able to observe surrounding traffic condi-
tions and could cause an accident.
!Never open the hood when the wiper arms
are folded forward.
For your convenience, we recommend that you
have this work carried out by an authorized
Mercedes-Benz Center.
!Do not pull on the wiper blade inserts. They
could tear.
!Hold on to the wiper arm. If released, the
force of the impact from the tensioning spring
could crack the windshield.
