Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.

ist workshops: (Y page 26). Running-in notes
Important safety notes
In certain driving and driving safety systems,
the sensors adjust automatically while a cer-
tain distance is being driven after the vehicle has been delivered or after repairs. Full sys-
tem effectiveness is not reached until the end
of this teach-in process.
Brake pads/linings and discs that are either
new or have been replaced only achieve opti- mum braking effect after several hundred kil-
ometres of driving. Compensate for the
reduced braking effect by applying greater
force to the brake pedal. The first 1,500 km
If you treat the engine with sufficient care
from the very start, you will be rewarded with excellent performance for the remainder of
the engine's life.
R Drive at varying road speeds and engine
speeds for the first 1,500 km.
R Avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R When changing gears manually, change up
in good time, before the rev counter needle reaches
Ôof the way to the red area of the
rev counter.
R Do not shift down a gear manually in order
to brake.
R Try to avoid depressing the accelerator
pedal beyond the point of resistance (kick- down).
R All vehicles (except Mercedes-AMG
vehicles): drive the vehicle mainly in drive
program Efor the first 1500 km.
Additional notes on running in Mercedes-
AMG vehicles:
R Do not drive at speeds above 140 km/ hfor
the first 1,500 km.
R Only allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
R Drive the vehicle mainly in drive program C
for the first 1,500 km.
After 1,500 km, you may gradually accelerate the vehicle to full road and engine speeds.
You should also observe these notes on run-
ning-in if the engine or parts of the drive train
on your vehicle have been replaced.
Always observe the maximum permissible
speed. Driving

the vehicle could pull away suddenly. There is a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
Depress the accelerator carefully when pull-
ing 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 92).
It is only possible to shift the transmission
from position Pto the desired position if you
depress the brake pedal. Only then is the
parking lock released.
If you do not depress the brake pedal, 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 converter to reach its operating
temperature more quickly.
Information on automatically releasing the
electrical parking brake (Y page 183).
Hill start assist Hill start assist helps you when pulling away
forwards 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 footfrom the brake pedal to the accelerator pedal
and depress it before the vehicle begins to
roll. G
WARNING
After a while, hill start assist no longer holds
the vehicle and it may roll away. There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if:
R you are pulling away on a level road or a
downhill gradient

ECO start/stop function
Introduction The ECO start/stop function switches the
engine off automatically if the vehicle is stop-
ped under certain conditions.
When pulling away again, the engine starts
automatically. The ECO start/stop function
thereby helps you to reduce the fuel con-
sumption and emissions of your vehicle.
Important safety notes G

the multifunction display, the ECO start/stop function switches the engine off automati-
cally once the vehicle stops moving.
If the ECO start/stop function has been man-
ually deactivated (Y page 166) or a malfunc-
tion has caused the system to be deactivated,
the è ECO symbol is not displayed. The ECO start/stop function is only available
in drive program E(drive program Con
Mercedes-AMG vehicles).
Automatic engine switch-off If the vehicle is braked to a standstill with the
transmission in Dor N, the ECO start/stop
function switches off the engine automati-
cally.
The ECO start/stop function is operational
and the èECO symbol is displayed in
green in the multifunction display, if:
R the indicator lamp in the ECO button is lit
green
R the outside temperature is within the range
that is suitable for the system
R the engine is at normal operating temper-
ature
R the set temperature for the vehicle interior
has been reached
R the battery is sufficiently charged
R the system detects that the windscreen is
not misted up when the air-conditioning
system is switched on
