148Driving and operating9Warning
If the vehicle battery is discharged,
the vehicle must not be towed,
tow-started or jump-started as the
steering wheel lock cannot be
disengaged.
Operation on vehicles with
electronic key system in case of
failure
If either the electronic key fails or the
battery of the electronic key is weak,
a message may be displayed in the
Driver Information Centre.
Hold the electronic key with buttons
outside at the marking on the steering column cover as shown in the
illustration.
Operate the clutch pedal (manual
transmission), the brake pedal and
press Start/Stop .
This option is intended for
emergencies only. Replace the
electronic key battery as soon as
possible 3 24.
For unlocking or locking the doors,
see fault in radio remote control unit
or electronic key system 3 26.Starting the engine
Vehicles with ignition switch
Turn key to position 1 to release the
steering wheel lock.
Manual transmission: operate clutch
and brake pedal.
Automatic transmission: operate
brake pedal and move selector lever
to P or N.
Do not operate accelerator pedal.
Diesel engines: wait until control
indicator ! extinguishes.
154Driving and operatingEngine exhaust9Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Exhaust filter
Automatic cleaning process
The exhaust filter system filters soot particles out of the exhaust gases.
The start of saturation of the exhaust
filter is indicated by the temporary
illumination of % or C ,
accompanied by a message in the
Driver Information Centre.
As soon as the traffic conditions
permit, regenerate the filter by driving at a vehicle speed of at least 60 km/huntil the control indicator
extinguishes.
Note
On a new vehicle, the first exhaust
filter regeneration operations may
be accompanied by a burning smell,
which is normal. Following
prolonged operation of the vehicle at very low speed or at idle, water
vapour can be emitted at the
exhaust on acceleration. This does
not affect the behaviour of the
vehicle or the environment.
Cleaning process not possible
If % or C stays on, accompanied
by an audible signal and a message,
this indicates that the exhaust filter
additive level is too low.
The reservoir must be topped-up
without delay. Seek the assistance of
a workshop.Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.Caution
Fuel grades other than those listed on pages 3 205, 3 263 could
damage the catalytic converter or
electronic components.
Unburnt petrol will overheat and
damage the catalytic converter.
Therefore avoid excessive use of the starter, running the fuel tank
dry and starting the engine by
pushing or towing.
In the event of misfiring, uneven
engine running, a reduction in engine performance or other unusual
problems, have the cause of the fault
rectified by a workshop as soon as
possible. In an emergency, driving
can be continued for a short period,
keeping vehicle speed and engine
speed low.
156Driving and operatingAdditionally, control indicator u
will flash and a chime will sound. Refill AdBlue as soon as possible
before the AdBlue tank is
completely empty. Otherwise, a
restart of the engine will not be
possible.
When driving, the chime sounds
and the message is displayed
every 10 km until the additive tank
has been topped-up.
4. The last warning level is entered when the AdBlue tank is empty.
Restart of the engine is not
possible. The following warning
message will be displayed:
Top up emissions additive:
Starting prevented
Additionally, control indicator u
will flash and a chime will sound.
Refill the tank to a level of at least
5 l of AdBlue, otherwise restarting
of the engine is not possible.
Note
For D16DT engines, different levels
apply.High emission warnings
In the event of a fault with the
emissions control system, different messages are displayed in the Driver Information Centre. The messages
and the restrictions are a legal
requirement.
1. If a fault is detected for the first time, the warning Emissions fault
is displayed.
Additionally, control indicators u,
R and Z will illuminate and a
chime will sound. Driving is
possible without any restrictions.
If it is a temporary fault, the alert
disappears during the next
journey, after self-diagnosis of the emissions control system.
2. If the fault is confirmed by the emission control system, thefollowing message will be
displayed:
Emissions fault: Starting
prevented in 1100 km .
Additionally, control indicators u,
C and Z will illuminate and a
chime will sound.When driving, the message is
displayed every 30 s while the
fault persists.
3. If the last warning level is entered,
the following warning message
will be displayed:
Emissions fault: Starting
prevented
Additionally, control indicators u,
C and Z will illuminate and a
chime will sound.
Consult a workshop for
assistance.
Refilling AdBlueCaution
Only use AdBlue that complies
with European standards
DIN 70 070 and ISO 22241-1.
Do not use additives.
Do not dilute AdBlue.
Otherwise the selective catalytic
reduction system could be
damaged.
160Driving and operatingPull right paddle + to shift to a higher
gear.
Pull left paddle - to shift to a lower
gear.
Multiple pulls allow gears to be
skipped.
The selected gear is indicated in the
instrument cluster.
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. This can
cause a message in the Driver
Information Centre.
In manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions.
Gear shift indication
The symbol R or S with a number
beside it is indicated when
gearshifting is recommended for fuel
saving reasons.
Shift indication appears only in
manual mode.Electronic driving
programmes
● Following a cold start, the operating temperature
programme increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
● Special programmes automatically adapt the shifting
points when driving up inclines or
down hills.
● In snowy or icy conditions or on other slippery surfaces, the
electronic transmission control
enables the driver to select
manually first, second or third
gear for starting off.
Kickdown Pressing down the accelerator pedal
beyond the kickdown detent will lead to maximum acceleration
independent of selected driving
mode. The transmission shifts to a
lower gear depending on engine
speed.Fault
In the event of a fault a message is
displayed in the Driver Information Centre.
Vehicle messages 3 117.
Electronic transmission control
enables only third gear. The
transmission no longer shifts
automatically.
Do not drive faster than 100 km/h.
Have the cause of the fault remedied by a workshop.
Eco mode
Driving and operating163Fault9Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Parking brake
9 Warning
Before leaving the vehicle, check
parking brake status. Control
indicator j illuminate constantly
when electric parking brake is
applied.
Manual parking brake9 Warning
Always apply parking brake firmly
without operating the release
button, and apply as firmly as
possible on a downhill or uphill
slope.
To release the parking brake, pull
the lever up slightly, press the
release button and fully lower the
lever.
To reduce the operating forces of
the parking brake, depress the
foot brake at the same time.
