GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
Roverheat and cause a fire
Rlose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
!Do not warm up the engine with the vehicle
stationary. Drive off immediately. Avoid high
engine speeds and driving at full throttle until
the engine has reached its operating temper-
ature.
Only shift the automatic transmission to the
desired drive position when the vehicle is sta-
tionary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
!Mercedes-AMG vehicles: at low engine oil
temperatures below 68 ‡ (+20 †), the max-
imum engine speed is restricted in order to
protect the engine. To protect the engine and
maintain smooth engine operation, avoid driv-
ing at full throttle when the engine is cold.
Key positions
SmartKey
gTo remove the SmartKey
1Power supply for some consumers, such as
the windshield wipers
2Ignition (power supply for all consumers)
and drive position
3To start the engine
iThe SmartKey can be turned in the ignition
lock even if it is not the correct SmartKey for
the vehicle. The ignition is not switched on.
The engine cannot be started.
Start/Stop button
General notes
When you insert the Start/Stop button into the
ignition lock, the system needs approximately
two seconds recognition time. You can then use
the Start/Stop button.
Pressing the Start/Stop button several times in
succession corresponds to the different Smart-
Key positions in the ignition lock. This is only the
case if you are not depressing the brake pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
A check which periodically establishes a radio
connection between the vehicle and the Smart-
Key determines whether a valid SmartKey is in
the vehicle. This occurs, for example, when
starting the engine.

When checking the oil level:
Rpark the vehicle on a level surface
Rthe engine should be switched off for approx-
imately five minutes if the engine is at normal
operating temperature
Rall vehicles (except Mercedes ‑AMG C 63
and Mercedes ‑AMG C 63 S):if the engine is
not at normal operating temperature, e.g. if
the engine was started only briefly, wait
approximately 30 minutes before carrying out
the measurement
Mercedes ‑AMG C 63 and Mercedes ‑AMG C
63 S: the oil level must only be checked when
the engine is at normal operating temperature.
Checking the oil level using the oil dip-
stick
Check the oil level with the oil dipstick (exam-
ple)
XPull oil dipstick :out of the dipstick guide
tube.
XWipe off oil dipstick :.
XSlowly slide dipstick :into the guide tube to
the stop, and take it out again after approx-
imately three seconds.
If the level is between MIN mark =and MAX
mark ;, the oil level is correct.
XIf the oil level has dropped to MIN mark =or
below, add 1.1 US qt (1.0 l)of engine oil.
Adding engine oil
HEnvironmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful to
the environment.
!Use only engine oils and oil filters that are
approved for vehicles with a service system. A list of the engine oils and oil filters that have
been tested and approved in accordance with
Mercedes-Benz Specifications for Service
Products is available at any authorized
Mercedes-Benz Center.
The following cause engine failure or damage
to the exhaust system:
RUse of engine oils and oil filters that have
not been expressly approved for the service
system
RReplacement of engine oil and oil filter after
the replacement interval specified by the
service system has expired
RUse of engine oil additives
!Do not add too much oil. adding too much
engine oil can result in damage to the engine
or to the catalytic converter. Have excess
engine oil siphoned off.
Add engine oil (example)
XTurn cap :counter-clockwise and remove it.
XAdd engine oil.
If the oil level is at or below the MIN mark on
the oil dipstick, add 1.1 US qt (1.0 l)of engine
oil.
XReplace cap :on the filler neck and tighten
clockwise.
Ensure that the cap locks into place securely.
XCheck the oil level again with the oil dipstick
(Ypage 283).

Maintenance and care
Z

XWipe the wooden trim and trim pieces with a
damp, lint-free cloth, e.g. a microfiber cloth.
XTrim elements with piano black finish:
wipe with a soft, damp cotton cloth. Use clean
water.
XHeavy soiling:use care and cleaning prod-
ucts recommended and approved by
Mercedes-Benz.
Cleaning the seat covers
General notes
!Do not use a microfiber cloth to clean covers
made out of real leather, artificial leather or
DINAMICA. If used often, these can damage
the cover.
Note that regular care is essential to ensure that
the appearance and comfort of the covers is
retained over time.
Genuine leather seat covers
!To retain the natural appearance of the
leather, observe the following cleaning
instructions:
RClean genuine leather covers carefully with a damp cloth and then wipe the covers
down with a dry cloth.
RMake sure that the leather does not
become soaked. It may otherwise become
rough and cracked.
ROnly use leather care agents that have
been tested and approved by Mercedes-
Benz. You can obtain these from a qualified
specialist workshop.
Leather is a natural product.
It exhibits natural surface characteristics, for
example:
Rdifferences in the texture
Rmarks caused by growth and injury
Rslight nuances of color
These are characteristics of leather and not
material defects.
Seat covers of other materials
!Observe the following when cleaning:
Rclean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e.g. dish washing liquid).
Rclean cloth covers with a microfiber cloth
moistened with a solution containing 1% detergent (e.g. dish washing liquid). Rub
carefully and always wipe entire seat sec-
tions to avoid leaving visible lines. Leave
the seat to dry afterwards. Cleaning results
depend on the type of dirt and how long it
has been there.
Rclean DINAMICA covers with a damp cloth.
Make sure that you wipe entire seat sec-
tions to avoid leaving visible lines.
Cleaning the seat belts
GWARNING
Seat belts can become severely weakened if
bleached or dyed. This could cause the seat
belts to tear or fail, for instance, in the event of an accident. This poses an increased risk of
injury or fatal injury.
Never bleach or dye the seat belts.
!Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts by
heating at temperatures above 176 ‡(80 †)
or in direct sunlight.
XUse clean, lukewarm water and soap solution.
Cleaning the headliner and carpets
XHeadliner: if it is very dirty, use a soft brush or
dry shampoo.
XCarpets: use the carpet and textile cleaning
agents recommended and approved by
Mercedes-Benz.
