Notes on breaking-inanew vehicle
Important safety notes
New and replaced brakepads and discsonly
reachtheir optimum braking effect after
several hundred kilometers of driving.
Compensate for this by applyinggreater force
to thebrakepedal.
Thefirst 1000miles (1500 km)
The moreyou look after theengine when it is
new, themoresatisfied you will be with its
performanceinthefuture.
RYou should therefore driveatvarying
vehicle and engine speedsfor thefirst
1000 miles (1500 km).
RAvoid heavy loads, e.g.driving at full
throttle, during this period.
RChange gearingood time, before the
tachometer needle isof the way to the
red area of the tachometer.
RDo not manually shift toalower gear to
brake the vehicle.
RIf possible, do not depress the accelerator
pedal past the point of resistance
(kickdown).
ROnly select shift ranges3,2or1when
driving slowly, e.g. in mountainous terrain.
After 1000 miles (1500 km), you can increase
the engine speed graduallyand accelerate
the vehicle to full speed.
Additional breaking-in notes for AMG
vehicles:
RDo not drive faster than 85 mph
(140 km/h) for the first 1000 miles
(1500 km).
ROnly allow the engine to reachamaximum
engine speed of 4500 rpm briefly.
RChange gear in good time.

breaking in if the engine or parts of the drive
train on your vehicle have been replaced.
iAlways observe the respective speed
limits.
AMG vehicles with self-locking rear
axle differential

General notes
The Lane Tracking package consistsofBlind
Spot Assist (Ypage 207) and Lane Keeping
Assist (Ypage 209).
Blind Spot Assist
General notes
Blind Spot Assist usesaradar sensor system
to monitor the areas on both sides of your
vehicle. It supports you fromaspeed of
approximately 20 mph(30km/h).Awarning
displayinthe exteriormirrors draws your
attention to vehicles detected in the
monitored area. If you thenswitchonthe
correspondingturnsignal to change lanes,
you will also receiveavisual and audible
collision warning. BlindSpot Assist uses
sensors in the rear bumper for monitoring
purposes.
For BlindSpot Assist to assist you, the radar
sensor system must be operational.
Important safety notes
GWARNING
BlindSpot Assist does not reactto:
Rvehicles overtaken too closely on the side,
placingtheminthe blind spot area
Rvehicles which approach withalarge speed
differential and overtake your vehicle
Asaresult, Blind Spot Assist may not give
warnings in such situations. There isarisk of
an accident.
Always observe the traffic conditions
carefully, and maintainasafe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for

Active Blind Spot Assist
Generalnotes
Active Blind Spot Assistusesaradar sensor
system, pointed toward the rear of the
vehicle, to monitor the area to the sides of the
vehicle which the driver is unable to see. A
warning displayinthe exterior mirrors draws
your attention to vehicles detected in the
monitored area. If you then switch on the
corresponding turn signal to change lane, you
will also receive an optical and audible
warning. Ifarisk of lateral collision is
detected, corrective braking may help you
avoidacollision. Beforeacourse-correcting
brake application, Active Blind Spot Assist
evaluates the space in the direction of travel
and at the sides of the vehicle. For this, Active
Blind Spot Assist uses radar sensors which
are pointed in the direction of travel.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
