Driving and operating225Driving 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 3 105.
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 3 228.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
226Driving and operatingthan 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 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 1,500 km.
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.
Stop-start system 3 228.
Diesel particle filter 3 233.
Ignition switch positions Turn key:0:ignition off: Some functions
remain active until key is
removed or driver's door is
opened, provided the ignition was
on previously1:accessory power mode: Steering wheel lock released, some
electrical functions are operable,
ignition is off2:ignition is on, diesel engine is
preheating. Control indicators
illuminate and most electrical
functions are operable3:engine start: Release key after
starting procedure begins
Driving and operating229Deactivation
Deactivate the stop-start system
manually by pressing ).
Deactivation is indicated when the
LED in the button illuminates.
To reactivate, press Ï again. The
LED extinguishes in the button. The system is reactivated automatically
the next time the ignition is switched
on.
Note
When the fast idle function is
activated, the stop-start system is
automatically deactivated and
cannot be reactivated by pressing
Ï . LED in button illuminates to
indicate deactivation and a
corresponding message may
appear in the Driver Information
Centre 3 105.
Idle speed control 3 228.
AutostopManual transmission
If the vehicle is at low speed or
standstill, activate an Autostop as
follows:
● depress the clutch pedal
● move the selector lever to neutral
● release the clutch pedal
Control indicator Ï may flash if the
clutch is not released sufficiently.Manual transmission automated
If the vehicle is at a standstill, activate an Autostop as follows:
● selector lever in position D, M or
N
● depress brake pedal firmly
● do not accelerate
The engine will be switched off while
the ignition stays on if the required
conditions are fulfilled.
An Autostop is indicated when Ï
illuminates 3 103.
During an Autostop, the heating
performance, power steering and
brake performance will be
maintained. Brake assist, however, is
not available 3 246.
Note
If you exit the vehicle while the
engine is in an Autostop, a warning
chime will sound as a reminder that
the engine is on standby and has not been switched off.9 Warning
Switch off engine and ignition
before exiting the vehicle.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled,
otherwise an Autostop will be
inhibited and control indicator \ will
illuminate.
● the stop-start system is not manually deactivated
● the bonnet is fully closed
Driving and operating231Restart of the engine by the stop-start system
If one of the conditions for an
Autostop is not fulfilled anymore or
the vehicle starts to move, the engine
may be restarted automatically by the
stop-start system.
An automatic engine restart may not
be possible if a door or the bonnet is
open.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during restart might be noticeable.
If the Infotainment system is active,
audio sound may briefly be reduced
or interrupted during the restart.
Fault
If the LED illuminates in deactivation
button ) without first being pressed
to deactivate the system, there is a
fault in the stop-start system and it is
deactivated. A corresponding
message also appears in the Driver
Information Centre 3 105.
Seek the assistance of a workshop.Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply parking brake without pressing release
button. Apply as firmly as
possible on a downhill slope or
uphill slope. Depress brake
pedal at the same time to
reduce operating force.
● Switch off the engine.
● If the vehicle is on a level surface or uphill slope, engage
first 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 24 and activate the
anti-theft locking system 3 35 and
anti-theft alarm system 3 36.
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 3 316 or the
vehicle documents.
