The PRE-SAFE
®
Brake function can also brake
the vehicle automatically under the following
conditions:
R the driver and front passenger have their seat
belts fastened
R the vehicle speed is between approximately
7 km/h and 200 km/h
At speeds of up to approximately 70 km/h, PRE-
SAFE ®
Brake can also detect:
R stationary objects in the path of your vehicle,
e.g. stopped or parked vehicles
R pedestrians in the path of your vehicle
i If an increased danger of collision exists,
preventative passenger protection measures
(PRE-SAFE ®
) are triggered (Y page 55).
If the danger of collision with the vehicle in front remains and you do not brake, take evasive
action or accelerate quickly, the vehicle may
perform automatic emergency braking up to the
point of full brake application. Automatic full
brake application is not performed until imme-
diately prior to an imminent accident.
You can prevent the engagement of PRE-SAFE ®
Brake at any time by:
R depressing the accelerator pedal further
R activating kickdown
R releasing the brake pedal
The braking action of PRE-SAFE ®
Brake is ended
automatically if:
R you manoeuvre to avoid the obstacle
R the danger of collision has passed
R an obstacle is no longer detected in front of
your vehicle STEER CONTROL
General information STEER CONTROL helps you by transmitting a
noticeable steering force to the steering wheel
in the direction required for vehicle stabilisation.
This steering support is provided in particular if:
R both right wheels or both left wheels are on a
wet or slippery road surface when you brake
R the vehicle begins to skid Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 68).
No steering support is provided from STEER
CONTROL, if: R ESP ®
is deactivated
R ESP ®
is malfunctioning
R the steering is faulty
If ESP ®
is malfunctioning, you will be assisted
further by the electrical power steering. Protection against theft

Running-in notes
Important safety notes
In certain driving and driving safety systems, the sensors adjust automatically while a certain dis-
tance is being driven after the vehicle has been delivered or after repairs. Full system effective-
ness is not reached until the end of this teach-in process.
Brake pads/linings and discs that either are new or have been replaced achieve optimum braking
effect only after several hundred kilometres of
driving. Compensate for the reduced braking
effect by applying greater force to the brake
pedal. The first 1500 km
The more you treat the engine with sufficient
care at the start, the more satisfied you will be
with the engine performance later on.
R You should therefore drive at varying road
speeds and engine speeds for the first
1500 km.
R Avoid overstraining the vehicle during this
period, e.g. driving at full throttle.
R When shifting gears manually, shift up in good
time, before the rev counter needle reaches
Ô of the way to the red area of the rev counter
display.
R Do not shift down a gear manually in order to
brake.
R Try to avoid depressing the accelerator pedal
beyond the pressure point (kickdown).
After 1500 km, you can increase the engine
speed gradually and accelerate the vehicle to
full speed.
You should also observe these notes on running- in if the engine or parts of the drive train on your
vehicle have been replaced.
Always observe the maximum permissible
speed. Driving

cle in front and the stored speed light up. Rev counter
! Do not drive in the overrevving range. Doing
so will damage the engine.
The red band in the rev counter indicates the
engine's overrevving range.
The fuel supply is interrupted to protect the
engine when the red band is reached. Outside temperature display
You should pay special attention to road condi-
tions when temperatures are around freezing
point.
Bear in mind that the outside temperature dis-
play indicates the measured air temperature
and not the road surface temperature.
The outside temperature display is in the multi-
function display (Y page 230).

WARNING
If you open the bonnet while the engine is
overheating or while there is a fire in the
engine compartment, you could come into
contact with hot gases or other leaking ser-
vice products. There is a danger of injury.
Allow an overheating engine to cool down
before opening the bonnet. If there is a fire in the engine compartment, leave the bonnet
closed and notify the fire brigade.
The coolant temperature gauge is in the lower
section of the rev counter (Y page 34).

Towing away and tow-startingBreakdown assistance

When your vehicle is towed away or towed
started, you may require considerably more
effort to steer and brake. There is a risk of an
accident.
In such cases use a rigid towing bar. Before
being towed away or tow started, make sure
the steering moves freely. G
WARNING
If the steering wheel lock is engaged, the vehi- cle can no longer be steered. There is a risk of
an accident.
Always switch on the ignition when towing
with a tow rope or a towing bar. G
WARNING
When towing or tow-starting another vehicle
and its weight is greater than the permissible gross weight of your vehicle, the:
R towing eye may be torn off
R car/trailer combination may swerve or
even overturn
There is a risk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the per- missible gross weight of your vehicle.
Details on the permissible gross vehicle weight
of your vehicle can be found on the vehicle iden-
tification plate (Y page 372).
! When Active Brake Assist, Distance Pilot
DISTRONIC or the HOLD function is activated, the vehicle brakes automatically in certain
situations.
To avoid damage to the vehicle, deactivate
these systems in the following or similar sit-
uations:
R when towing away
R in a car wash
! Make sure that the electric parking brake is
released. If the electric parking brake is faulty, visit a qualified specialist workshop.
! Only secure the tow cable or tow bar to the
towing eyes or, if available, to the trailer tow
hitch. You could otherwise damage the vehi-
cle. !
Observe the following points when towing
with a tow rope:
R Secure the tow rope on the same side on
both vehicles.
R Make sure that the tow rope is not longer
than legally permitted. Mark the tow rope in
the middle, e.g. with a white cloth
(30 x 30 cm). This will make other road
users aware that a vehicle is being towed.
R Only secure the tow cable to the towing
eyes or, if available, to the trailer tow hitch.
R Observe the brake lamps of the towing
vehicle while driving. Always maintain a dis-
tance a distance so that the tow rope does not sag.
R Do not use steel cables or chains to tow
your vehicle. You could otherwise damage
the vehicle.
! Do not use the trailer tow hitch for recovery
or towing. Do not use the towing eye for
recovery. This could damage the vehicle. If in
doubt, have the vehicle recovered using a
crane.
! When towing, pull away slowly and
smoothly. If the tractive power is too high, the
vehicles could be damaged.
