138Driving and operating
Do not accelerate while engaging a
gear. Never depress the accelerator
pedal and brake pedal at the same
time.
When a gear is engaged, the vehicle
slowly begins to creep when the
brake is released.
Gears 3, 2, 13, 2, 1=Transmission does not
shift above the selected
gear.
Press button on selector lever to
engage 3 or 1.
Only select 3, 2 or 1 to prevent
automatic upshifting or as an aid in
engine braking.
Engine braking
To utilise the engine braking effect,
select a lower gear in good time when
driving downhill.
Rocking the vehicle
Rocking the vehicle is only
permissible if the vehicle is stuck in
sand, mud or snow. Move the selector
lever between D and R in a repeat
pattern. Do not race the engine and
avoid sudden acceleration.
Parking
Apply the parking brake and engage P .
The ignition key can only be removed
when the selector lever is in position
P .Manual mode
Move selector lever out of position D
towards the left and then forwards or backwards.
+=Shift to a higher gear.-=Shift to a lower gear.
If a higher gear is selected when
vehicle speed is too low, or a lower
gear when vehicle speed is too high,
the shift is not executed.
If engine speed is too low, the
transmission automatically shifts to a
lower gear above a specific vehicle
speed.

Stowage of coupling ball bar
In Saloons, the coupling ball bar is in
a pouch, fastened in the load
compartment cargo box with a strap.
In Station wagons, the coupling ball
bar is fastened with a strap in a
compartment in the spare wheel well
of the load compartment.
Fitting the coupling ball bar
Fold down the socket. Remove the
sealing plug from the hole for the
coupling ball bar and stow it in the
load compartment.
Checking the tensioning of the
coupling ball bar
■ Red marking on rotary knob must
point towards white marking on
coupling ball bar.
■ The gap between the rotary knob and the coupling ball bar must beapprox. 4 millimetres.
■ Key must be at position c ( 1).
Otherwise, the coupling ball bar must be tensioned before being inserted:
■ Unlock coupling ball bar by turning key to position c ( 1)
Page 159 of 245

Driving and operating157
■ Pull out rotary knob and turnclockwise as far as it will go.
Inserting the coupling ball bar
Insert the tensioned coupling ball bar
in the opening and push firmly
upwards until it audibly engages.
The rotary handle snaps back into its
original position resting against the
coupling ball bar without a gap.9 Warning
Do not touch rotary handle during
insertion.
Lock the coupling ball bar by turning
the key to position e ( 2). Remove the
key and close the protective flap.
Eye for break-away stopping cable
Attach break-away stopping cable to
eye.
Check that the coupling ball bar is
correctly installed
■ Green marking on rotary knob must
point towards white marking on
coupling ball bar.
■ There must be no gap between the
rotary handle and the coupling ball
bar.
■ The coupling ball bar must be firmly
engaged in the opening.
■ The coupling ball bar must be locked and the key removed.9 Warning
Towing a trailer is permitted only
when a coupling ball bar is fitted correctly. If the coupling ball bardoes not engage correctly, seekthe assistance of a workshop.

158Driving and operating
Dismounting the coupling ballbar
Open the protective flap and turn the
key to position c ( 1) to unlock the
coupling ball bar.
Pull out rotary handle and turn
clockwise as far as it will go. Pull out
coupling ball bar downwards.
Insert sealing plug in opening. Fold away socket.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is selectively braked until the snaking
ceases.
Trailer stability assistant (TSA) is a
function of the Electronic Stability
Program (ESP® Plus
) 3 147.

Vehicle care165
■ The vehicle battery containssulphuric acid which could cause
blindness or serious burn injuries.
■ See the Owner's Manual for further
information.
■ Explosive gas may be present in the vicinity of the vehicle battery.
Diesel fuel system
bleeding
If the tank has been run dry, the diesel
fuel system must be bled. Switch on
the ignition three times for
15 seconds at a time. Then crank the
engine for a maximum of 40 seconds. Repeat this process after
no less than 5 seconds. If the engine
fails to start, seek the assistance of a
workshop.Wiper blade replacement
Service setting for front
windscreen wipers
Switch off the ignition but do not
remove ignition key or open driver's
door.
Within 4 seconds, push the wiper
lever down and release as soon as
the wipers are vertical.
Wiper blades on the windscreen
Lift the wiper arm, tilt wiper blade at a
90° to the wiper arm and remove to
the side.

Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring.
Remove the valve cap key from the
fuel filler flap and use it to unscrew the
valve cap.
On vehicles with tyre pressure
monitoring system, screw the adapter
to the valve.
Tyre pressure 3 225 and on the label
on the inside of the fuel filler flap.
The tyre pressure data refer to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare wheel to the
pressure specified for full load.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible. It must not be used with run-flat tyres.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify drive axle and body style.
2. Identify the engine identifier code.
Engine data 3 216.
3. Identify the respective tyre.
