Driving and operating125first gear. On an uphill slope,
turn the front wheels away from
the kerb.
If the vehicle is on a downhill
slope, engage reverse gear.
Turn the front wheels towards
the kerb.
● Close the windows.
● Turn the ignition key to position
0 and remove it. Turn the
steering wheel until the
steering wheel lock is felt to
engage.
Lock the vehicle 3 21 and activate the
anti-theft locking system 3 31 and
anti-theft alarm system 3 31.
Air suspension
Operates automatically when the
vehicle is driven. The air suspension
system constantly adjusts the ride
height according to the vehicle load.
Caution
To ensure safe operation of the air
suspension system, do not exceed the maximum permissible gross
vehicle weight rating. Refer to
identification plate 3 204 or the
vehicle documents.
For further information on the air
suspension system, refer to the
operating instructions supplied.
Master switch
Caution
The air suspension system must
be switched off when the vehicle is being towed, jump‐started, raised
off the ground or transported.
Do not switch off the air
suspension system when driving.
Jump starting 3 193, Towing the
vehicle 3 195.
The master switch is located on the
door pillar.
Switch on to enable operation and
adjustment of the air suspension
system.
Driving and operating137Deactivation
The Laden mode is switched off by:
● pressing kg again
● turning off the ignition
Kickdown
If the accelerator pedal is pressed past the pressure point, the
transmission shifts to a lower gear
depending on engine speed. Full
engine power is available for
acceleration.
If engine speed is too high the
transmission switches to a higher
gear, even in manual mode. Without
kickdown this automatic shift is not
effected in manual mode.
Fault
In the event of a fault, control indicator W is shown in the transmission
display. Continued driving is possible
provided the vehicle is driven with
care and anticipation.
Have the cause of the fault remedied
by a workshop.Interruption of power supply
The clutch is not disengaged if there
is an interruption of the power supply
when a gear is engaged. The vehicle
cannot move.
If the vehicle battery is discharged,
start the vehicle using jump leads
3 193.
If the cause of the fault is not a
discharged vehicle battery, seek the
assistance of a workshop.
If neutral cannot be selected, the
vehicle must only be towed with the
drive wheels raised off the ground
3 195.
Towing the vehicle 3 195.Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when you depress the
brake pedal firmly. You need to use
considerably more force for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has
been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 88.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.

Vehicle care165Charging the vehicle battery9Warning
On vehicles with stop-start
system, ensure that the charging potential does not exceed
14.6 volts when using a battery
charger. Otherwise the vehicle
battery might be damaged.
9 Danger
Ensure adequate ventilation when
charging the battery. There is a
risk of explosion if gases
generated during charging are
allowed to accumulate!
Jump starting 3 193.
Warning label
Meaning of symbols:
● No sparks, naked flames or smoking.
● Always shield eyes. Explosive gases can cause blindness or
injury.
● Keep the vehicle battery out of reach of children.
● The vehicle battery contains sulfuric 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 battery.
Additional battery Depending on the vehicle's auxiliary
equipment, certain models may have
an additional battery mounted under
the front seat.
Diesel fuel filter
Drain diesel fuel filter of residual
water at every engine oil change.

4.Screw the compressor air hose to
the connection on the sealant
bottle.
5. Fit the sealant bottle into the retainer on the compressor.
Set the compressor near the tyre
in such a way that the sealant
bottle is upright.
6. Unscrew valve cap from defective
tyre.7. Screw the sealant filler hose to the
tyre valve.
8. The rocker switch on the compressor must be set to
position O.
9.
Connect the red < power supply
lead on the compressor to the
jump start terminal 3 193.
Notice
Depending on model, the jump start
terminal may be located at the left-
hand or right-hand side of the engine
compartment.
10. Connect the black ] power
supply lead to a vehicle grounding
point, e.g. the engine block or an
engine mounting bolt.

Vehicle care193● Do not drive faster than 50 mph.
● Drive particularly carefully on wet
and snow-covered road
surfaces.Jump starting
Do not start with a quick charger.
A vehicle with a discharged battery can be started using jump leads and
the battery of another vehicle.9 Warning
Be extremely careful when starting
with jump leads. Any deviation
from the following instructions can
lead to injuries or damage caused
by battery explosion or damage to the electrical systems of both
vehicles.
9 Warning
Avoid contact with eyes, skin,
fabrics, and painted surfaces. The fluid contains sulphuric acid which can cause injuries and damage in
the event of direct contact.
Caution
The air suspension system must
be switched off prior to jump
starting.
9 Warning
Avoid contact of the battery with
eyes, skin, fabrics and painted
surfaces. The fluid contains
sulphuric acid which can cause
injuries and damage in the event
of direct contact.
● Never expose the vehicle battery
to naked flames or sparks.
● A discharged vehicle battery can already freeze at a temperature
of 0 °C. Defrost the frozen vehicle
battery before connecting jump leads.
● Wear eye protection and protective clothing when
handling a vehicle battery.
194Vehicle care● Use a booster battery with thesame voltage (12 volts). Its
capacity (Ah) must not be much less than that of the discharged
vehicle battery.
● Use jump leads with insulated terminals and a cross section of
at least 25 mm 2
.
● Do not disconnect the discharged
battery from the vehicle.
● Switch off all unnecessary electrical consumers.
● Switch off the air suspension system 3 125.
● Do not lean over the vehicle battery during jump starting.
● Do not allow the terminals of one
lead to touch those of the other
lead.
● The vehicles must not come into contact with each other during
the jump starting process.
● Apply the parking brake and engage neutral (manual
transmission) or N (manual
transmission automated).Jump start terminal
In the event of a discharged vehicle
battery, the jump start terminal
enables the vehicle to be started
without the need to access the battery inside the vehicle.
The jump start terminal is located in
the engine compartment and
identified by a " <" sign on the red
insulating cover. Lift the red insulating
cover to access the terminal
connector.
Ensure the red insulating cover is
latched back into position when not in
use.
Jump starting procedure
Depending on model, the jump start
terminal may be located at the left-
hand or right-hand side of the engine
compartment.
Vehicle care195
Lead connection order:1. Connect the red lead to the positive terminal of the booster
battery.
2. Connect the other end of the red lead to the jump start terminal of
the vehicle with the discharged
vehicle battery.
3. Connect the black lead to the negative terminal of the booster
battery.
4. Connect the other end of the black
lead to a vehicle grounding point,
such as the engine block or an
engine mounting bolt. Connect as
far away from the discharged
vehicle battery as possible,
however at least 60 cm.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine: 1. Start the engine of the vehicle providing the jump start.
2. After 5 minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of
1 minute.
3. Allow both engines to idle for approx. 3 minutes with the leads
connected.
4. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
5. Reverse above sequence exactly when removing leads.Towing
Towing the vehicle
The towing eye is stowed with the vehicle tools 3 179.
Disengage the cover using a suitable
tool and remove.
Screw the towing eye clockwise into
the front towing point and tighten fully using the wheel wrench.
Attach a tow rope - or better still a tow
rod - to the towing eye, never to the
bumper or front suspension units.
