Driving and operating135Driving 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.
ActivationPress ECO. Control indicator
illuminates when activated and a corresponding message appears in
the Driver Information Centre 3 104.
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
extinguishes.
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 3 138.
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.
