Lighting111General informationPerformance of the system can be
affected due to the following:
● Extreme weather conditions, e.g.
heavy rain, fog or snow.
● The front camera or the windscreen is obstructed, e.g. bya portable navigation system.
● Oncoming or preceding vehicle lights are not detected.
● Headlights are not adjusted correctly.
● Various reflective surfaces may also cause the system to fail todetect other vehicles.
Headlight flash
To activate the headlight flash, pull
the lever briefly without passing the
resistance point.

The asymmetrical headlight beam
extends visibility at the edge of the
road at the passenger side.
However, when driving in countries
where traffic drives on the opposite
side of the road, adjust the headlights to prevent dazzling of oncoming
traffic.
Open the bonnet and adjust both
headlights with a screwdriver by
turning the screw a quarter turn in -
direction. Adjust to standard position
by turning the screw a quarter turn in
+ direction.

190Infotainment systemVoice recognitionGeneral information
The voice recognition function allows
to operate certain functions via voice
input.
To ensure that conversations held
inside the vehicle do not start
unintentional calls to a saved contact, the voice recognition function must
first be activated via 5 on the column
controls.
Control elements overview 3 121.
NAVI 50 IntelliLink Available depending on version, the
voice recognition function of the
handsfree phone system allows you
to operate certain functions of a
compatible smartphone via voice
input.
Refer to "Phone control" in this
section 3 192.
To confirm that a paired and
connected smartphone is compatible
with the voice recognition function, touch 7 followed by ÿSetting(s) .Then select Connectivity followed by
View Bluetooth device list . The list
shows the paired devices and 5
appears alongside the name of the
smartphone to indicate compatibility.
Notice
If supported, the language set on the
smartphone will automatically be
used by the Infotainment system for
voice recognition.
The navigation system can also be
operated using voice controls. Refer
to "Navigation control" in this section 3 191.
Prerequisites
The following prerequisites must be
met:
● The Bluetooth function of the Infotainment system must be
activated.
Refer to "Bluetooth connection"
in the "Phone" section 3 196.
● The Bluetooth function of the Bluetooth-enabled smartphone
must be activated and the
smartphone must have a 3G, 4Gor wi-fi connection (see
smartphone operating
instructions).
● Dependent upon the smartphone, it may be required
to set the device to "visible" (see smartphone operating
instructions).
● The smartphone must be paired and connected to the
Infotainment system.

224Driving and operatingDriving hints
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. When activated ECO
appears in the Driver Information
Centre.
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. ECO disappears in
the Driver Information Centre.
Driver Information Centre 3 104.
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 3 227.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
Page 227 of 351

Driving and operating225than 15 seconds, damage mayoccur 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 and after new
disc brake pads have been fitted.
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.
Limit the engine speed to 2,500/min
for the first 900 miles.
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
vehicle battery.

226Driving and operatingSteering wheel lock
Remove key from ignition switch and
turn steering wheel until it engages.9 Danger
Never remove the key from
ignition switch during driving as
this will cause steering wheel lock.
Starting the engine
Manual transmission: operate clutch.
Manual transmission automated:
operate brake; transmission
automatically shifts to N.
Do not accelerate.
Turn the key to position 2 for
preheating, and hold until control
indicator N extinguishes from the
Driver Information Centre.
Notice
Depending on vehicle, if a gear is
engaged during preheating, a
message may appear in the Driver
Information Centre (DIC) 3 104
indicating that the clutch pedal must be depressed when starting the
engine.
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.
Notice
Rear-wheel drive with twin rear
wheels and front-wheel drive: When
starting on a level surface with anunladen vehicle, it is recommended
that second gear is selected when
starting off.
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 3 227.
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.
