324 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 lever2 under 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 the hood is securely engaged be-
fore driving off. Do not continue driving if the
hood can no longer engage after an acci-
dent, for example. The hood could otherwise
come loose while the vehicle is in motion
and injure you and/or others.

370 Operation
Vehicle care
Soft top (CLK cabriolet)
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.!Make sure the windshield wiper switch is
set to0 (
page 56). 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 373). 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 the mir-
rors 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.

373 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 38).
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.
!Do not apply strong pressure to the sensor
covers. Applying strong pressure may damage
the sensor covers.
Follow the instructions provided by the power
washer manufacturer on maintaining a distance
between the vehicle and the nozzle of the power
washer.
!To prevent scratches, never apply strong
force and only use a soft, non-scratching cloth
when cleaning the sensors. Do not attempt to
wipe dirty sensors with a dry cloth or sponge.
!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.

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 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. Replace 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 at 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.
