Driving and operating

Driving hints

Control of the vehicle

Never coast with engine not

running (except during Autostop)

Many systems will not function in this

situation (e.g. brake servo unit, power

steering). Driving in this manner is a

danger to yourself and others. All

systems function during an Autostop,

but there will be a controlled reduction

in power steering assist and vehicle

speed is reduced.
Stop-start system 3 142.

Idle boost

If charging of the vehicle battery is

required due to battery condition, the

power output of the generator must

be increased. This will be achieved by

an idle boost which may be audible.
A message is displayed in the Driver

Information Centre.


To ensure the pedal travel is

uninhibited, there must be no mats in

the area of the pedals.
Use only floor mats which fit properly

and are fixed by the retainers on the

driver's side.


If power steering assist is lost

because the engine stops or due to a

system malfunction, the vehicle can

be steered but may require increased

Control indicator c 3 89.


Vehicles equipped with hydraulic

power steering:
If the steering wheel is turned until

it reaches the end of its travel, and

is held in that position for more

than 15 seconds, damage may

occur to the power steering

system and there may be loss of

power steering assist.

Starting and operating

New vehicle running-in

Do not brake unnecessarily hard for

the first few journeys.
During the first drive, smoke may

occur because of wax and oil

evaporating off the exhaust system.

Park the vehicle in the open for a

while after the first drive and avoid

inhaling the fumes.
During the running-in period fuel and

engine oil consumption may be

higher and the cleaning process of

the diesel particle filter may take

place more often. Autostop may be

inhibited to allow for charging the

Diesel particle filter 3 146.


Driving and operating


Ignition switch positions

0 : ignition off

1 : steering wheel lock released,

ignition off

Retained power off

The following electronic systems can

work until the driver's door is opened

or at the latest for ten minutes after

the ignition is switched off:

● power windows
● sunroof
● power outlets

Power to the Infotainment system will

continue to operate for 30 minutes or

until the key is removed from the

ignition switch, regardless of whether

any door will be opened.

Starting the engine

Manual transmission: operate clutch.
Automatic transmission: operate

brake and move the selector lever to

P or N.
Do not operate the accelerator pedal.

Diesel engine: turn the key to position

2 for preheating until control

indicator ! extinguishes.
Turn the key briefly to position 3 and

release: an automatic procedure

operates the starter with a short delay

as long as the engine is running, see

Automatic Starter Control.
Before restarting or to switch off the

engine, turn the key back to position

During an Autostop, the engine can

be started by depressing the clutch


Starting the vehicle at low


Starting the engine without additional

heaters is possible down to -25 °С for

diesel engines and -30 °C for petrol

engines. Required is an engine oil

with the correct viscosity, the correct

fuel, performed services and a

sufficiently charged vehicle battery.

With temperatures below -30 °C the

automatic transmission needs a

warming phase of approx. five

minutes. The selector lever must be

in position P.



Driving and operating

Automatic Starter Control

This function controls the engine

starting procedure. The driver does

not need to hold the key in position 3.

Once applied, the system will go on

starting automatically until the engine

is running. Because of the checking

procedure, the engine starts running

after a short delay.
Possible reasons for a non-starting


● Clutch pedal not operated

(manual transmission).

● Brake pedal not operated or

selector lever not in P or N

(automatic transmission).

● Timeout occurred.

Turbo engine warm-up

Upon start-up, engine available

torque may be limited for a short time,

especially when the engine

temperature is cold. The limitation is

to allow the lubrication system to fully

protect the engine.

Overrun cut-off

The fuel supply is automatically cut off

during overrun, i.e. when the vehicle

is driven with a gear engaged but

accelerator pedal is released.
Depending on driving conditions, the

overrun cut-off may be deactivated.

Stop-start system

The stop-start system helps to save

fuel and to reduce the exhaust

emissions. When conditions allow, it

switches off the engine as soon as the

vehicle is at a low speed or at a

standstill, e.g. at a traffic light or in a

traffic jam. It starts the engine

automatically as soon as the clutch is

depressed. A battery sensor ensures

that an Autostop is only performed if

the vehicle battery is sufficiently

charged for a restart.


The stop-start system is available as

soon as the engine is started, the

vehicle starts-off and the conditions

as stated below in this section are



Deactivate the stop-start system

manually by pressing eco. The

deactivation is indicated when the

LED in the button extinguishes.


If the vehicle is at a low speed or at a

standstill, activate an Autostop as


● Depress the clutch pedal.
● Move the selector lever to


● Release the clutch pedal.


Driving and operating


The engine will be switched off while

the ignition stays on.

system may inhibit an Autostop. See

"Climate control" chapter for more

details 3 132.
Immediately after motorway driving,

an Autostop may be inhibited.
New vehicle running-in 3 140.

Vehicle battery discharge protection

To ensure reliable engine restarts,

several battery discharge protection

features are implemented as part of

the stop-start system.

Power saving measures

During an Autostop, several electric

features, e.g. auxiliary electric heater

or heated rear window are disabled or

switched into a power saving mode.

The fan speed of the climate control

system is reduced to save power.

Engine exhaust

9 Danger

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.



Driving and operating

Diesel particle filter

Automatic cleaning process

The diesel particle filter system filters

harmful soot particles out of the

exhaust gases. The system includes

a self-cleaning function that runs

automatically during driving without

any notification. The filter is cleaned

by periodically burning off the soot

particles at high temperature. This

process takes place automatically

under set driving conditions and may

take up to 25 minutes. Typically it

needs between seven and twelve

minutes. Autostop is not available

and fuel consumption may be higher

during this period. The emission of

smells and smoke during this process

is normal.

System requires cleaning

Under certain conditions, e.g. driving

short distances, the system cannot

clean itself automatically.
If cleaning of the filter is required and

if previous driving conditions did not

enable automatic cleaning, it will be

indicated by illumination of % and a

warning message in the Driver

Information Centre.

Catalytic converter

The catalytic converter reduces the

amount of harmful substances in the

exhaust gases.


Fuel grades other than those listed

on pages 3 1883 262 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,
