Start the engine using the SmartKey.. Move
the transmission to Nwith the E-SELECT
lever. Use the SmartKey to switch the
engine off again and then turn the
SmartKey to position 2. Make sure that you
then leave the SmartKey in position 2. You
may otherwise damage the vehicle, the
transmission or the car wash.
Check the transmission position in the
instrument cluster.
! Use the E-SELECT lever to shift the
transmission to Nbefore switching the
engine off. If you open the driver's or front-
passenger door, the transmission remains
in this position for up to 30 minutes if the
SmartKey is in the ignition, even if the
engine is switched off. If you do not shift
the transmission to Nusing the E-SELECT
lever beforehand, it shifts automatically to
parking position Pand locks the wheels if
the driver's or front-passenger door is
opened and the engine is switched off. This
may damage the vehicle, the transmission
or the car wash.
Observe the information on maneuvering
(Y page 131).
! Before driving into an automatic car wash,
make sure that it is suitable for the
dimensions of the vehicle. In particular,
make sure that:
R there is enough ground clearance
between the vehicle underbody and the
guide rails of the automatic car wash.
R the clearance width of the automatic car
wash is sufficient, particularly the width
of the guide rails.
R you enter the automatic car wash
straight and in the center of the guide
rails in order to avoid damaging the tires
or wheel rims.
Fold in the exterior mirrors before the
vehicle is washed. The exterior mirrors
could otherwise be damaged. !
Make sure that:
R the side windows and the roof are
completely closed
R the climate control blower is switched off
R the windshield wiper switch is at position
0
The vehicle could otherwise be damaged.
! In portal car washes, the windshield
wipers may be moved up the windshield by
the cleaning brushes when the ignition is
switched off.
Set the Start/Stop button to key position
2 to reset the windshield wipers to their
original position.
! Preferably use automatic car washes with
adjustable high-pressure pre-cleaning. This
corresponds with the specification for the
Cabriolet program. In car washes that use
high water pressures, there is a risk that a
small amount of water may leak into the
vehicle.
! Cabriolet: do not treat the vehicle with
hot wax under any circumstances.
After using an automatic car wash, wipe off
wax and drying agents from the windshield
and the wiper blades. This will prevent smears
and reduce wiping noises caused by residue
on the windshield.
Washing by hand In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements in each
country.
X
Do not use hot water and do not wash the
vehicle in direct sunlight.
X Use a soft sponge to clean.
X Use a mild cleaning agent, such as a car
shampoo approved by Mercedes-Benz.
X Thoroughly hose down the vehicle with a
gentle jet of water.
X Do not point the water jet directly towards
the air inlet. 224

Gross axle weight rating:
the maximum
permissible weight that can be carried by one
axle (front or rear axle).
To ensure that your vehicle does not exceed
the maximum permissible values (gross
vehicle weight and maximum gross axle
weight rating), have your loaded vehicle
(including driver, occupants, cargo, and full
trailer load if applicable) weighed on a
suitable vehicle weighbridge. All about wheels and tires
Uniform Tire Quality Grading
Standards
Overview of Tire Quality Grading
Standards Uniform Tire Quality Grading Standards are
U.S. government specifications. Their
purpose is to provide drivers with uniform
reliable information on tire performance data.
tire manufacturers have to grade tires using
three performance factors: tread wear 0043,
tire traction 0044and heat resistance 0087. All
tires sold in North America are provided with
the corresponding quality class mark on the
sidewall of the tire, even though these
regulations do not apply to Canada.
Quality grades can be found, where
applicable, on the tire sidewall between the
tread shoulder and maximum tire width. Example:
R
Treadwear grade: 200
R Traction grade: AA
R Temperature grade: A
All passenger car tires must conform to the
statutory safety requirements in addition to
these grades.
i The actual values for tires are vehicle-
specific and may deviate from the values in
the illustration.
Treadwear The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
U.S. government course. For example, a tire
graded 150 would wear one and one-half
times as well on the government course as a
tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly from
the norm due to variations in driving habits,
service practices and differences in road
characteristics and climate conditions.
Traction
G
WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
! Avoid wheelspin. This can lead to damage
to the drive train.
The traction grades – from highest to lowest
– are AA, A, B and C. Those grades represent
the tire's ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete. A tire marked C may have poor
traction performance. All about wheels and tires

Additives
!
Do not use any additives in the engine oil.
This could damage the engine.
Engine oil viscosity Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity,
this means that it is thick; a low viscosity
means that it is thin.
Select an engine oil with an SAE classification
(viscosity) suitable for the prevailing outside temperatures. The table shows you which
SAE classifications are to be used. The low-
temperature characteristics of engine oils
can deteriorate significantly, e.g. as a result
of aging, soot and fuel deposits. It is therefore
strongly recommended that you carry out
regular oil changes using an approved engine
oil with the appropriate SAE classification.
Refrigerant of the air-conditioning
system
Important safety notes Type of refrigerant
The climate control system of your vehicle is
filled with refrigerant R-134a.
The instruction label regarding the refrigerant
type used can be found on the radiator cross
member.
Refrigerant R-134a
!
Only the refrigerant R-134a and the PAG
oil approved by Mercedes-Benz may be
used. The approved PAG oil may not be
mixed with any other PAG oil that is not
approved for R-134a refrigerant.
Otherwise, the climate control system may
be damaged.
Service work, such as topping-up refrigerant
or replacing components, may only be carried
out by a qualified specialist workshop. All
applicable regulations must be adhered to,
SAE standard J639 included.
Always have work on the climate control
system carried out at a qualified specialist
workshop.
