2014 MERCEDES-BENZ B-CLASS HATCHBACK automatic transmission

i
The function of the electric parking brake
and the parking lock is dependent on the
on-board voltage.
If the on-board voltage is low or if there is a system malfunction:
R it may not be possible to apply the
released parking brake or
R it may not be possible to shift the trans-
mission to position P
i Switch off non-essential consumers, such
as the radio.
i Deactivate the automatic locking feature
before the vehicle is towed away
(Y page 247). You could otherwise be
locked out when pushing or towing the
vehicle.
Deactivate tow-away protection before the vehicle is towed away . Fitting/removing the towing eye
Fitting the towing eye Example: covers for towing eye mountings
X Remove the towing eye from the stowage
space.
The towing eye is located with the vehicle
tool kit under the luggage compartment
floor (Y page 333). Vehicles with a TIREFIT kit: the towing eye
is located under the tyre inflation compres-
sor.
X Press the mark on cover :inwards in the
direction of the arrow.
X Remove cover :from the opening.
X Screw in the towing eye clockwise to the
stop.
Vehicles with a trailer tow hitch only have a
bracket at the front for the screw-in towing
eye. If you intend to use the vehicle for tow-
ing, fold out the ball coupling (Y page 226)
and secure the towbar to it.
Removing the towing eye X
Loosen the towing eye and unscrew it.
X Attach cover :to the bumper and press
until it engages.
X Place the towing eye in the stowage well
(Y page 333) under the luggage compart-
ment floor.
X Vehicles with a TIREFIT kit: replace the tyre
inflation compressor. Towing the vehicle with the front axle
raised
When towing your vehicle away with the rear axle raised, it is important that you observe
the safety instructions (Y page 344).
Only vehicles without 4MATIC can be
towed with the front axle raised.
! Vehicles with 4MATIC must not be towed
with the front or rear axle raised; otherwise, the transmission may be damaged.
Vehicles with 4MATIC may either be towed
away with both axles on the ground or be loa-
ded up and transported.
! The ignition must be switched off if you
are towing the vehicle with the front axle
raised. Intervention by ESP ®
could other-
wise damage the brake system. 346

the
automatic transmission automatically shifts
to position Pwhen you open the driver's or
front-passenger door or when you remove the
key from the ignition lock. In order to ensure that the automatic transmission stays in posi- tion Nwhen towing away the vehicle, you
must observe the following points:
X Make sure that the vehicle is stationary.
X Turn the key to position 2in the ignition
lock.
X Depress the brake pedal and keep it
depressed.

All vehicles:
X Leave the key in position 2in the ignition
lock.
X Release the brake pedal.
X Release the electric parking brake.
X Switch on the hazard warning lamps
(Y page 125).
i In order to signal a change of direction
when towing the vehicle with the hazard
warning lamps switched on, use the com-
bination switch as usual. In this case, only
the turn signals for the desired direction
flash. When you reset the combination
switch, the hazard warning lamps start
flashing again. Transporting the vehicle

X Secure the vehicle.
The towing eyes or trailer tow hitch can be
used to pull the vehicle onto a trailer or trans- porter if you wish to transport it. Notes for 4MATIC vehicles
! Vehicles with 4MATIC must not be towed
with the front or rear axle raised; otherwise, the transmission may be damaged.
Vehicles with 4MATIC may only be either
towed away with both axles on the ground or be loaded up and transported.
If the vehicle has transmission damage or
damage to the front or rear axle, have it trans-
ported on a transporter or trailer.
In the event of damage to the electrical
system:
If the battery is defective, the automatic
transmission will be locked in position P. To
shift the automatic transmission to position
N, you must provide power to the vehicle's electrical system in the same way as when
jump-starting (Y
page 342).
Have the vehicle transported on a transporter
or trailer. Tow-starting (emergency engine
starting)
! Do not tow-start vehicles with automatic
transmission. You could otherwise damage the automatic transmission.
i You can find information on "Jump-start-
ing" under (Y page 342).
Before tow-starting, the following conditions
must be fulfilled: R the battery is connected
R the engine has cooled down
R the exhaust system has cooled down
When tow-starting, it is important that you
observe the safety notes (Y page 344) and the
legal requirements in each respective coun-
try.
X Switch on the hazard warning lamps
(Y page 125).
X Fit the towing eye (Y page 346).
X Secure the rigid towing bar or the towing
rope.
X When the vehicle is stationary, depress the
brake pedal and keep it depressed.

depress the accelerator pedal while doing
so.
X When the engine has been started, imme-
diately depress the clutch pedal fully and
shift to neutral. 348
Towing away and tow-startingBreakdown assistance

Interchanging the front and rear wheels of
differing dimensions can render the general
operating permit invalid.
Observe the instructions and safety notes in
the "Changing a wheel" section (Y page 361).
The wear patterns on the front and rear tyres differ depending on the operating conditions.
Interchange the wheels before a clear wear
pattern has formed on the tyres. Front tyres
typically wear more on the shoulders and the
rear tyres in the centre.
On vehicles that have the same size front and rear wheels, you can interchange the wheels
every 5,000 to 10,000 km depending on the
degree of tyre wear. Ensure the direction of
rotation is maintained.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tyre pressure and, if necessary, restart the tyre pressure loss
warning system or the tyre pressure monitor. Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of aquaplaning. These advantages can only be gained if the tyres are fitted corresponding to the direction of rotation.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation. Storing wheels
Store wheels in a cool, dry and preferably
dark place if they are not being used. Protect
the tyres against oil, grease, petrol and diesel. Fitting a wheel
Preparing the vehicle X
Stop the vehicle on solid, non-slippery and
level ground.
X Apply the electric parking brake manually. X
Move the front wheels to the straight-
ahead position.
X Vehicles with manual transmission:
depress the clutch pedal fully and engage
first or reverse gear.
X Vehicles with automatic transmission:
shift the transmission to position P.
X Switch off the engine.
X Vehicles without KEYLESS-GO: remove
the key from the ignition lock.
X Vehicles with KEYLESS-GO start-func-
tion or KEYLESS-GO: open the driver's
door.
The on-board electronics now have status
0. This is the same as the key having been
removed.
X Vehicles with KEYLESS-GO start func-
tion or KEYLESS-GO: remove the Start/
Stop button from the ignition lock
(Y page 159).
X If included in the vehicle equipment,
remove the tyre-change tool kit from the
vehicle.
X Safeguard the vehicle against rolling away
(Y page 181).
i Apart from some country-specific var-
iants, vehicles are not equipped with tyre-
changing tools. Some tools for changing a
wheel are specific to the vehicle. For more information on which tools are required to
perform a wheel change on your vehicle,
consult a qualified specialist workshop.
Necessary tyre-changing tools may
include, for example:
R Jack
R Wheel chock
R Wheel wrench 362
