Notes on breaking-in a new vehicle
Important safety notes
The sensor system of some driving and driv-
ing 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 proce-
dure.
New and replaced brake pads and discs only
reach their optimum braking effect after sev-
eral hundred kilometers of driving. Compen-
sate 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
performance in the future.
RYou should therefore drive at varying vehi-
cle and engine speeds for the first
1,000 miles (1,500 km).
RAvoid heavy loads, e.g. driving at full throt-
tle, during this period.
RChange gear in good time, before the tach-
ometer needle is Ôof the way to the red
area of the tachometer.
RDo not manually shift to a lower gear to
brake the vehicle.
RTry to avoid depressing the accelerator
pedal beyond the point of resistance (kick-
down).
RIdeally, for the first 1,000 miles (1,500 km),
drive in program C.
After 1,000 miles (1,500 km), you can
increase the engine speed gradually and bring
the vehicle to full speed.
Additional breaking-in notes for Mercedes-
AMG vehicles:
RDo not drive faster than 85 mph
(140 km/h) for the first 1,000 miles
(1,500 km).
ROnly allow the engine to reach a maximum
engine speed of 4,500 rpm briefly.
RChange gear in good time.
You should also observe these notes on
breaking in if the engine or parts of the drive
train on your vehicle have been replaced.
Always observe the maximum permissible
speed.
Self-locking rear axle differential
(Mercedes-AMG vehicles)
Your vehicle is equipped with a self-locking
differential on the rear axle.
Change the oil to improve protection of the
rear axle differential:
Rafter a breaking-in period of 1,850 miles
(3,000 km)
Revery 31,000 miles (50,000 km) or
3 years
These oil changes prolong the service life of
the differential. Have the oil change carried
out at a qualified specialist workshop.

Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshifting the automatic transmission out of
park position P
RStart the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
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.
GWARNING
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.
!Do not depress the accelerator when
starting the engine.

iMercedes-AMG vehicles:the exhaust
flap of the exhaust system is checked after
each cold start. A resulting noise can be
heard during this process.
iDuring a cold start, the engine runs at
higher speeds to enable the catalytic con-
verter to reach its operating temperature.
The sound of the engine may change during
this time.
Automatic transmission
XShift the transmission to position P.
The transmission position display in the
multifunction display shows P.
iYou can start the engine in transmission
position Pand N.
Starting procedure with the SmartKey
To start the engine using the SmartKey
instead of KEYLESS-GO, pull the Start/Stop
button out of the ignition lock.
XTurn the SmartKey to position 3in the igni-
tion lock and release it as soon as the
engine is running (
Ypage 139).
Using KEYLESS-GO to start the engine
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.
XDepress the brake pedal and keep it
depressed.
XPress the Start/Stop button once
(
Ypage 140).
The engine starts.
Pulling away
General notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
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.
!Change gear in good time and avoid spin-
ning the wheels. You could otherwise dam-
age the vehicle.
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 (
Ypage 206).
It is only possible to shift the transmission
from position Pto the desired position if you
depress the brake pedal. Only then is the shift
lock released.
iUpshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Information on the automatic release of the
electric parking brake (
Ypage 161).
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 foot
from the brake pedal to the accelerator pedal
and to depress it before the vehicle begins to
roll.
