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.

Active Driving Assistance package
General notes
The Active Driving Assistance package con-
sists of DISTRONIC PLUS (
Ypage 182), Active
Blind Spot Assist (
Ypage 214) and Active
Lane Keeping Assist (
Ypage 217).
Active Blind Spot Assist
General notes
Active Blind Spot Assist uses a radar sensor
system to monitor the side areas of your vehi-
cle which are behind the driver. A warning
display in the exterior mirrors draws your
attention to vehicles detected in the moni-
tored area. If you then switch on the corre-
sponding turn signal to change lanes, you will
also receive an optical and audible collision
warning. If a risk of lateral collision is detec-
ted, corrective braking may help you avoid a collision. To support the course-correcting
brake application, Active Blind Spot Assist
also uses the forward-facing radar sensor sys-
tem.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be operational.
Important safety notes
Active Blind Spot Assist is only an aid. It may
fail to detect some vehicles and is no substi-
tute for attentive driving.
GWARNING
Active Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
