Protection of the environment
General notes
H Environmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected
by these factors: R
operating conditions of your vehicle R
your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions: R
avoid short trips as these increase fuel con-
sumption. R
always make sure that the tire pressures
are correct. R
do not carry any unnecessary weight. R
remove roof racks once you no longer need
them. R
a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals. R
always have service work carried out at a
qualified specialist workshop.
Personal driving style: R
do not depress the accelerator pedal when
starting the engine. R
do not warm up the engine when the vehicle
is stationary. R
drive carefully and maintain a safe distance
from the vehicle in front. R
avoid frequent, sudden acceleration and
braking. R
change gear in good time and use each gear
only up to

death or serious bodily injury if the vehicle is
driven, that defect or malfunction has been
subject to repair two or more times, and you
have directly notified Mercedes-Benz USA,
LLC in writing of the need for its repair.
(2) the same substantial defect or malfunction
of a less serious nature than category (1)
has been subject to repair four or more
times and you have directly notified
Mercedes-Benz in writing of the need for its
repair.
(3) the vehicle is out of service by reason of
repair of the same or different substantial
defects or malfunctions for a cumulative
total of more than 30 calendar days.

tions of KEYLESS-GO with those of a conven-
tional SmartKey. Unlock the vehicle by using
KEYLESS-GO, for instance, and lock it using the
7 button on the SmartKey.
When locking or unlocking with KEYLESS-GO,
the distance between the SmartKey and the cor-
responding door handle must not be greater
than 3 ft (1 m).
A brief radio connection between the vehicle
and the SmartKey determines whether a valid
SmartKey is in, or in the direct vicinity of, the
vehicle. This occurs, for example: R
when the external door handles are touched R
when starting the engine R
while the vehicle is in motion

Notes on breaking-in a new vehicle
Important safety notes The sensor system of some driving and driving
safety systems adjusts automatically while a
certain distance is being driven after the vehicle
has been delivered or after repairs. Full system
effectiveness is not reached until the end of this
teach-in procedure.
New and replaced brake pads and discs only
reach their optimum braking effect after several
hundred kilometers of driving. Compensate for
this by applying greater force to the brake pedal.
The first 1000 miles (1500 km) The more you look after the engine when it is
new, the more satisfied you will be with its per-
formance in the future. R
You should therefore drive at varying vehicle
and engine speeds for the first 1000 miles
(1500 km). R
Avoid heavy loads, e.g. driving at full throttle,
during this period. R
Change gear in good time, before the tach-
ometer needle is

these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
G WARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system or
parts of the engine that heat up. There is a risk
of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
General notes
i The catalytic converter is preheated for up
to 30 seconds after a cold start. The sound of
the engine may change during this time.
Automatic transmission X
Shift the transmission to position P .
The transmission position display in the mul-
tifunction display shows P .
i You can start the engine in transmission
position P and N .
Starting procedure with the SmartKey
i To start the engine using the SmartKey
instead of KEYLESS-GO, pull the Start/Stop
button out of the ignition lock. X
Turn the SmartKey to position 3 in the ignition
lock ( Y
page 123) and release it as soon as the
engine is running.
Using KEYLESS-GO to start the engine
i The Start/Stop button can be used to start
the vehicle manually without inserting the
SmartKey into the ignition lock. The Start/
Stop button must be inserted in the ignition
lock and the SmartKey must be in the vehicle.
This mode for starting the engine operates
independently of the ECO start/stop auto-
matic engine start function. X
Depress the brake pedal and keep it
depressed. X
Press the Start/Stop button once
( Y
page 123).
The engine starts.
Pulling away
General notes
G WARNING
If the engine speed is above the idling speed
and you engage transmission position D or R ,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position D or R ,
always firmly depress the brake pedal and do
not simultaneously accelerate.
! If a warning tone sounds and the Release
Park. Brake message appears in the multi-
function display, the parking brake is still
applied. Release the parking brake.
Depress the accelerator carefully when pulling
away.
The vehicle locks centrally once you have pulled
away. The locking knobs in the doors drop down.
You can open the doors from the inside at any
time.
You can also deactivate the automatic locking
feature ( Y
page 199).
It is only possible to shift the transmission from
position P to the desired position if you depress
the brake pedal. If the brake pedal is not
depressed, the DIRECT SELECT lever can still be
moved but the parking lock remains engaged.
i Upshifts take place at higher engine speeds
after a cold start. This helps the catalytic con-
verter to reach its operating temperature
more quickly.
Hill start assist
Hill start assist helps you when pulling away for-
wards or in reverse on an uphill gradient. It holds
the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and to
depress it before the vehicle begins to roll. Driving 125

i You can only change gear with the steering
wheel paddle shifters when the transmission
is in position D .
Automatic drive program
Automatic drive program E (C) Drive program E (drive program C on Mercedes-
AMG vehicles) is characterized by the following: R
comfort-oriented engine and automatic trans-
mission settings. R
optimal fuel consumption resulting from the
automatic transmission shifting up sooner. R
the vehicle pulls away more gently in forward
and reverse gears, unless the accelerator
pedal is depressed fully. R
the vehicle has improved driving stability, for
example on slippery road surfaces. R
the automatic transmission shifting up
sooner. This results in the vehicle being driven
at lower engine speeds and the wheels being
less likely to spin. Automatic drive program S Drive program S (or, in the case of Mercedes-
AMG vehicles, drive programs S and S+ ) is char-
acterized by the following: R
sporty engine and automatic transmission
settings. R
the automatic transmission shifts up later.
The fuel consumption possibly being higher
as a result of the later automatic transmission
shift points.
Manual drive program M General notes In this drive program, you can briefly change
gear yourself by using the steering wheel paddle
shifters. The transmission must be in position D .
You can activate manual drive program M in
automatic drive programs E , C and S .
Mercedes-AMG vehicles and vehicles with
AMG sports package: as well as temporary
drive program M you can also activate perma-
nent drive program M ( Y
