Switching off the engine
Important safety notes
GWARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away. There is a risk of an
accident.
After switching off the engine, always switch
to parking position P. Prevent the parked vehi-
cle from rolling away by applying the parking
brake.
!If the coolant temperature is very high, e.g.
after driving on hilly roads, leave the engine
running at idle speed for about two minutes
before turning it off.
This allows the coolant temperature to return
to normal.
Vehicles with automatic transmission
XStop the vehicle.
XShift the transmission to position P.
XApply the parking brake.
XTurn the key to position0in the ignition lock
and remove it.
The immobilizer is activated.
If you switch the engine off with the trans-
mission in position Ror D, the automatic
transmission shifts to Nautomatically.
If you then open one of the front doors or
remove the key from the ignition, the auto-
matic transmission automatically shifts to P.
If you shift the automatic transmission to N
before switching off the engine, the automatic
transmission remains in Neven if a front door
is opened.
XSecure the vehicle to prevent it from rolling
away (Ypage 133).
Parking the vehicle for a long period
If you leave the vehicle parked for longer than
four weeks, the battery may be damaged by
exhaustive discharging.
XDisconnect the battery (Ypage 259).
or
XConnect the battery to a trickle charger.
Be sure to observe the notes on charging the batteries (
Ypage 262).
You can obtain information about trickle
chargers from a qualified specialist work-
shop.
If you leave the vehicle parked for longer than 6
weeks, the vehicle may suffer damage as a
result of lack of use.
XVisit a qualified specialist workshop and seek
advice.
Driving tips
General notes
Important safety notes
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If you operate mobile communication equip-
ment while driving, you will be distracted from traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements of the country in
which you are driving. Some jurisdictions pro-
hibit the driver from using a mobile phone while driving a vehicle.

Driving and parking

Active Parking Assist does not assist you park-
ing in spaces at right angles to the direction of
travel if:
Rtwo parking spaces are located directly next
to one another
Rthe parking space is directly next to a low
obstacle such as a low curb
Ryou forward park
Active Parking Assist does not assist you park-
ing in spaces that are parallel or at right angles
to the direction of travel if:
Rthe parking space is on a curb
Rthe system reads the parking space as being
blocked, for example by foliage or grass pav-
ing blocks
Rthe area is too small for the vehicle to maneu-
ver into
Rthe parking space is bordered by an obstacle,
e.g. a tree, a post or a trailer
:Detected parking space on the left
;Parking symbol
=Detected parking space on the right
If the driver's seat belt is fastened and all doors
are closed, Active Parking Assist is activated
automatically when driving forwards. The sys-
tem is operational at speeds of up to approx-
imately 22 mph (35 km/h). While in operation,
the system independently locates and meas-
ures parking spaces on both sides of the vehicle.
Active Parking Assist will only detect parking
spaces:
Rparallel or at right angles to the direction of
travel
Rthat are parallel to the direction of travel and are at least 59 in (1.5 m) wide
Rthat are parallel to the direction of travel and
at least 40 in (1.0 m) longer than your vehicle
Rthat are at right angles to the direction of
travel and at least 40 in (1.0 m) widerthan
your vehicle
iNote that Active Parking Assist cannot
measure the length of a parking space if it is at right angles to the direction of travel. You will
need to judge whether your vehicle will fit in
the parking space.
When the vehicle is driving at speeds of up to
approximately 20 mph (30 km/h), parking sym-
bol ;is shown as a status display in the header.
The syste m d
etects and differentiates between
parking spaces which are parallel or at right
angles to the direction of travel. When a parking
space is detected, an arrow appears next to
parking symbol ;to indicate which side the
parking space is on. The parking space is dis-
played while you are driving past it and until you
are approximately 50 ft (15 m) away from it.
Active Parking Assist displays parking spaces on
the passenger side as standard. The parking
spaces on the driver's side are only displayed if
you operate the turn signal on the driver's side.
When parking on the driver's side, you must
operate the turn signal until you have started
active parking assistance by pressing the a
button on the steering wheel.
Parking
GWARNING
If you leave the driver's seat when the vehicle is only being braked by Active Parking Assist,
the vehicle could roll away if:
Rthere is a malfunction in the system or in
the voltage supply.
Rthe electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with.
Rthe battery is disconnected.
Rthe vehicle is accelerated, e.g. by a vehicle
occupant.
There is a risk of an accident.
Before leaving the driver's seat, always secure the vehicle against rolling away.
If PARKTRONIC detects obstacles, Active Park-
ing Assist brakes automatically during the park- ing process. You are responsible for braking in
good time.

rating (GCWR), nor the maximum permissible
gross axle weight rating (GAWR) and trailer
drawbar noseweight rating of your vehicle.
RAdd the drawbar noseweight on the ball cou-
pling (TWR) to the rear axle load. This will pre-vent you from exceeding the permissible
gross axle weight (GAWR).
RAdd the drawbar noseweight on the ball cou-
pling (TWR) to the vehicle payload. This will
ensure that you do not exceed the permissi-
ble gross vehicle weight rating (GVWR).
Checking the vehicle and trailer weight
RMake sure the weights of the towing vehicle
and the trailer comply with the maximum per-missible values. Have the vehicle/trailer com-
bination weighed on a calibrated weigh-
bridge. The vehicle/trailer combination con-
sists of the towing vehicle including the driver,
passengers and load, as well as the loaded
trailer.
RCheck the maximum permissible gross axle
weight rating of the front and rear axles
(GAWR), the gross trailer weight (GTW), the
gross combination weight rating (GCWR) and
the noseweight of the trailer drawbar (TWR).
Trailer power supply
!
Incorrect wiring of the connector plug could,
under certain circumstances, cause malfunc-
tions in the vehicle's other electronic sys-
tems. We therefore recommend having the
connector plug wired at a qualified specialist
workshop.
!You can connect accessories with a maxi-
mum power consumption of 240 W to the
permanent power supply.
You must not charge a trailer battery using the
power supply.
Your vehicle may be equipped with various elec-
trical installations for trailer towing. Depending
on your trailer, you may need an adapter to con-
nect the electrical system of the trailer with that
of the vehicle.
The trailer socket of your vehicle is equipped at
the factory with a permanent power supply.
The permanent power supply is on the trailer
socket pin assignment 4.
Note that the permanent power supply of the
trailer is not switched off when the on-board voltage is low. This can completely discharge
the starter battery of your vehicle.
Further information on the electrical equipment
currently installed on your vehicle and on instal-
ling trailer electrics can be obtained at any quali-
fied specialist workshop.
