Instruments and controls105Trip computer
The trip computer provides
information on driving data, which is
continually recorded and evaluated electronically.
Depending on vehicle, the following
functions can be selected by pressing button repeatedly on end of wiper
lever:
● fuel used
● average consumption
● instantaneous consumption
● range
● distance travelled
● average speed
● AdBlue percentage remaining 3 141
● distance before service 3 93
● clock 3 88
● outside temperature 3 87
● cruise control and speed limiter stored speed 3 152
● fuel economy rating (ecoScoring)
● fault and information messages
● odometer 3 91
● trip odometer 3 91
Fuel used Displays the amount of fuel
consumed since the last reset.
The measurement can be restarted at
any time by pressing and holding the
button.
Average consumption The value is displayed after driving a
distance of 400 metres.Average consumption is displayed,
taking into consideration the distance
travelled and the fuel used since the
last reset.
The measurement can be restarted at
any time.
Instantaneous consumption
The value is displayed after reaching
a speed of 30 km/h.
Range The value is displayed after driving adistance of 400 metres.
The range is calculated from the
current contents of the fuel tank and
the average consumption since the
last reset.
The range will not display if control
indicator Y is illuminated in the
instrument cluster 3 101.
Distance travelled
Displays the distance driven since the
last reset.
The measurement can be restarted at
any time.

Instruments and controls107Interruption of power supply
If the power supply has been
interrupted or if the vehicle battery
voltage has dropped too low, the
values stored in the trip computer will be lost.Tachograph
The tachograph is operated as
described in the operating
instructions supplied. Observe
regulations regarding use.
Depending on equipment, the
tachograph may be fitted in a console located above the Infotainment
system in the instrument panel.
Note
When a tachograph is fitted, the total
distance travelled may be shown
only on the tachograph and not in the odometer within the instrument
display.

Driving economically
ECO mode ECO mode is a function that
optimises fuel consumption. It affects
engine power and torque,
acceleration, gear shift indication,
heating, air conditioning and electrical consumers.
Activation
Press ECO. Control indicator ECO
illuminates in the instrument cluster when activated.
Page 133 of 237

Driving and operating131Note
The use of ECO mode may affect the
performance of the climate control
system 3 116.
During driving, it is possible to
temporarily disable ECO mode, e.g.
to increase engine performance, by
depressing the accelerator pedal
firmly.
ECO mode is reactivated when
pressure is reduced on the
accelerator pedal.
Deactivation
Press ECO again. Control indicator
ECO extinguishes in the instrument
cluster.
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 may be a controlled
reduction in power steering assist and
vehicle speed is reduced.
Stop-start system 3 136.
Pedals
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.
Driving downhill
Engage a gear when driving downhill
to ensure that sufficient brake
pressure is available.Steering
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
effort.Caution
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.

134Driving and operatingThese functions stop working when
the driver's door is opened and the
vehicle is locked.
Note
Always take the electronic key with you when exiting the vehicle.
The electronic key being left in the
card reader is indicated by a warning
chime 3 104 and a message in the
Driver Information Centre 3 103
when the driver's door is opened.9 Danger
Never leave an electronic key
inside the vehicle when children or animals are left in the vehicle, to
avoid unintended operation of
windows, doors or engine. Risk of
fatal injury.
Fault
If the engine cannot be started, the
cause may be one of the following:
● Fault in electronic key.
● Electronic key out of reception range.
● Battery voltage too low.
● Overload of the central locking system by operating at frequentintervals, the power supply is
interrupted for a short time.
● Interference from higher-power radio waves from other sources.
Battery replacement 3 22.
Central locking system 3 26.
Electronic key system 3 24.
Starting the engine
Manual transmission: operate clutch.
Do not accelerate.
Diesel engines: turn the key to
position 2 for preheating until control
indicator ! extinguishes in the
instrument cluster 3 100.
Turn key to position 3 and release.
The increased engine speed
automatically returns to normal idling
speed as the engine temperature
rises.
Start attempts should not last longer
than 15 seconds. If engine does not
start, wait 15 seconds before
repeating starting procedure. If
necessary, depress accelerator
before repeating starting procedure.
Before restarting or to switch off the
engine, turn key back to 0.
During an Autostop, the engine can
be started by depressing the clutch
pedal.
Stop-start system 3 136.

Driving and operating135Turbo engine warm-upUpon 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.
Idle speed control
To increase the idle speed, press the switch. After a few seconds the
function will be activated.
The function will be deactivated
when:
● The clutch pedal is depressed.
● The accelerator pedal is depressed.
● Vehicle speed is above 0 km/h. ● Control indicator F, W or C
illuminate in the instrument
cluster.
To increase or decrease the fast idle
speed rate, consult a workshop.
Note
When the fast idle function is
activated, the stop-start system is
automatically deactivated.
Stop-start system 3 136.
Vehicle shutdown
Fuel cut-off system
If the vehicle runs out of fuel, the fuel
system is cut-off and must be reset
after refuelling. A corresponding
warning message may also appear in the Driver Information Centre 3 102.9
Danger
If you can smell fuel in the vehicle,
or a fuel leak is present, have thecause of this remedied
immediately by a workshop. Do
not reset the fuel cut-off system, to avoid the risk of fire.
Resetting with remote control
key / manual key
To reset the fuel cut-off system and
enable the vehicle to be driven:
1. Turn the ignition key to position 2
3 132.
2. Wait a few minutes to allow the fuel system to be reset.
3. Turn key to position 3 to start the
engine.
If the engine does not start, repeat the
procedure.
