Driving economically Fuel economy mode
Fuel economy mode is a function that optimises fuel consumption. It affects,
e.g., engine power and torque,
acceleration and gear shift indication.
Manual transmissionActivation
Press s on the instrument panel;
LED in the button illuminates to
indicate activation.
Driving and operating123Deactivation
Press s again; LED in the button
extinguishes.
Stop-start system 3 126.
Automatic transmission
Activate fuel economy mode to allow
the transmission to adapt gearshift
patterns, improving the vehicle's fuel
economy.
Activation
In automatic mode, press s.
Control indicator s illuminates in
the instrument cluster 3 89.
The settings of certain electronic
systems are adapted to reduce fuel
consumption:
● The engine reacts less quickly to
the accelerator pedal.
● Automatic upshift points occur sooner and downshift points
occur later.
● The transmission locks itself to the engine at cruising speeds, to
improve efficiency and increase
power and torque.
● The fuel supply is automatically cut-off more quickly during
vehicle deceleration. Overrun
cut-off 3 126.
Do not use fuel economy mode whilst towing, e.g. a trailer.Deactivation
Press s again; control indicator
s 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 will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 126.
124Driving and operatingPedals
To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.
SteeringCaution
Never leave the steering wheel on
full lock when the vehicle is
stationary, as this may damage
the power steering pump.
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.
Electric power steering Electric power steering does not havepower steering fluid. Regular
maintenance is not required.
Note
If the steering wheel is turned until it
reaches the end of its travel, and is
held in that position for an extended
period of time, power steering assist
may be reduced. If used for an
extended period of time, power
steering assist may be reduced.
Normal use of the power steering
assist should return when the
system cools down.
If power steering assist is lost due to
a system malfunction, the vehicle can
be steered but may require increased
effort. Seek the assistance of a
workshop.
Control indicator 2 3 86.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 of the
battery.
Diesel particle filter 3 129.
Driving and operating129● Lock the vehicle by pressing p
on the radio remote control 3 22.
Activate the anti-theft alarm
system 3 26.Engine exhaust9 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.
Malfunction indicator light 3 84.
Diesel particle filter
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 more than
15 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.
Under certain driving conditions, e.g.
short distances, the system cannot
clean itself automatically.
