position 2 and activate combination switch for left or
right turn signal in usual manner – only the selected
turn signal will operate.
Upon canceling the turn signal, the hazard warning
flasher will operate again.Caution!
If the vehicle is towed with the front axle raised, the
engine must be shut off (electronic key in steering lock

Additional turn signals on the exterior mirror
The high mounted stop lamp (3rd brake lamp), and the
additional turn signals on the exterior mirrors are
equipped with LEDs.
Have the system checked at an authorized
Mercedes-Benz Center if a fault or defect occurs.Adjusting headlamp aim
Correct headlamp adjustment is extremely important.
To check and readjust a headlamp, follow steps 1
through 5.
Please note:
•Low beam adjustments simultaneously aim the high
beam.
•Vehicle should have a normal trunk load.
1. Park vehicle on level surface approximately 25 ft.
(7.6 m) from a vertical test screen or wall. The
centerline of the vehicle must be at a 90° angle to
the test screen.

cluster displayPractical hintsCar care Index Raising soft top manually
In case of malfunction, the power soft top can also be
raised manually. This procedure should be performed
with great care by two persons.
We recommend to take off your watch or other jewelry to
prevent personal injury.
A combination open-end / hex-socket wrench in the
vehicle tool kit is required for this job.
1. Engage parking brake.
2. Lower windows and open doors.
3. Lower roll bar with roll bar switch.
Note:
If the roll bar cannot be lowered, carefully guide the
soft top across the roll bar. Lift the rear window over
the roll bar.
4. For safety reasons, remove electronic key from
steering lock. Important!
Ensure that the trunk lid is closed while raising the soft
top manually. Otherwise there is the possibility of
contact between the trunk lid and the soft top
compartment cover.
Wa r n i n g !
Do not place your hands near the roll bar, soft top
frame, upper windshield area or soft top storage
compartment or between the soft top rods while the
soft top is being raised and locked. Serious personal injury may occur.

Cleaning and care of the vehicle

Cleaning and care of the vehicle
In operation, your vehicle is subjected to varying
external influences which, if gone unchecked, can
attack the paintwork as well as the underbody and
cause lasting damage.
Such damage is caused not only by extreme and varying
climatic conditions, but also by air polution, road salt,
tar, gravel and stone chipping. Grease and oil, fuel,
coolant, brake fluid, bird droppings, insects, tree resins
etc. should be removed immediately to avoid paint
damage. Frequent washing reduces and/or eliminates
the aggressiveness and potency of the above adverse
influences.More frequent washings are necessary to deal with
unfavorable conditions; for example, near the ocean, in
industrial areas (smoke, exhaust emissions), or during
winter operation.
You should check your vehicle from time to time for
stone chipping or other damage. Any damage should be
repaired as soon as possible to prevent the start of
corrosion.
In doing so, do not neglect the underside of the vehicle.
A prerequisite for a thorough check is a washing of the
underbody followed by a thorough inspection. Damaged
areas need to be reundercoated.
Your vehicle has been treated at the factory with a wax-
base ru stpro of ing in th e bo dy cavities w hich will la st for
the lifetime of the vehicle. Post-production treatment is
neither necessary nor recommended by Mercedes-Benz
because of the possibility of incompatibility between
materials used in the production process and others
applied later.
We have selected car-care products and compiled
recommendations which are specially matched to our
vehicles and which always reflect the latest technology.
You can obtain Mercedes-Benz approved car-care
products at your authorized Mercedes-Benz Center.
Warning!
Many cleaning products can be hazardous. Some
are poisonous, others are flammable. Always follow
the instructions on the particular container.
Always open your vehicle’s doors or windows when
cleaning the inside.Never use fluids or solvents that are not designed
for cleaning your vehicle.

Engine oils are specifically tested for their suitability in
our engines. Therefore, use only engine oils
recommended by Mercedes-Benz. Information on
recommended brands is available at your authorized
Mercedes-Benz Center.
Please follow Service Booklet recommendations for
scheduled oil changes. Failure to do so could result in
engine damage not covered by the Mercedes-Benz
Limited Warranty.
Engine oil additives
Do not blend oil additives with engine oil. They may be
harmful to the engine operation.
Damage or malfunctions resulting from blending oil
additives are not covered by the Mercedes-Benz Limited
War ra nt y.Air conditioner refrigerant
R-134a (HFC) refrigerant and special PAG lubricating oil
is used in the air conditioner system.
Never use R-12 (CFC) or mineral-based lubricating oil,
otherwise damage to the system will occur.
Brake fluid
During vehicle operation, the boiling point of the brake
fluid is continuously reduced through the absorption of
moisture from the atmosphere. Under extremely hard
operating conditions, this moisture content can lead to
the formation of bubbles in the system thus reducing
the system’s efficiency.
The brake fluid must therefore be replaced every two
years, preferably in the spring.
It is recommended to use only brake fluid approved by
Mercedes-Benz. Your authorized Mercedes-Benz Center
will provide you with additional information.
