Driving
For the first 1,000 km, do not exceed two thirds
of the engine’s maximum rpm speed and do not
accelerate at full throttle. You can increase the
engine speed gradually over the next 500 km.
– Depending on the equipment in your vehi-
cle, coasting may only be possible when the
cruise control system is active.
Plug-in hybrid drive
Applies to: vehicles with plug-in hybrid drive
Conventional and mild hybrid drive
Applies to: vehicles with conventional drive systems or mild
hybrid drive
On plug-in hybrid vehicles, you can choose be-
tween electric and combustion engine drive
modes or a combination of both ðpage 119,
ðpage 115
Vehicles with conventional drive systems or mild
hybrid drive are powered by a combustion engine
which burns fuel to generate energy.
Coasting
Vehicles with mild hybrid drive are equipped with
additional battery technology.
Just like conventional drive vehicles, the combus-
tion engine can be disengaged on plug-in hybrid
vehicles to save fuel. In this mode, which is simi-
lar to coasting, the vehicle rolls without the en-
gine braking effect. However, the electric part of
the drive system remains engaged and is able to
recuperate energy if the conditions permit.
Coasting mode may be activated when you take
your foot off the accelerator.
Coasting
Applies to: vehicles with coasting function
Coasting can be used to save fuel. When the vehi-
cle is coasting, the combustion engine is disen-
gaged and the vehicle rolls without the engine
braking effect. Coasting mode may be activated
between 55 km/h and 160 km/h when you take
your foot off the accelerator.
Note
Depending on the equipment fitted in the vehi-
cle, you may be able to switch coasting mode
on/off under Intelligent coasting in the Efficien-
cy assist menu ðpage 190.
Coasting is not possible in all driving pro-
grams.
Recuperation
Applies to: vehicles with plug-in hybrid drive
The combustion engine may be switched off au-
tomatically on vehicles with mild hybrid drive
when coasting is activated.
A recuperation feature allows the vehicle to re-
cover energy. A large amount of the kinetic ener-
gy is thereby converted into electrical energy and
stored in the battery of the hybrid drive system.
The recuperation process causes the vehicle to
decelerate in addition to the engine braking ef-
fect. The recuperation process may be activated
in transmission position D when you press the
brake pedal or take your foot off the accelerator.
WARNING
When coasting is activated, there is no longer
an engine braking effect and the vehicle does
not slow down as quickly as usual or may even
pick up speed if you are driving down a slope –
risk of accident!
Note
Because the recuperation feature is used to slow
the vehicle down when you press the brake pedal,
the brakes are only used in addition as necessary.
This means that, by adopting a moderate driving
style, it is possible to brake the vehicle almost
down to a standstill using the recuperation func-
tion.
– You can cancel coasting by applying the ac-
celerator or brakes. Slight corrective brake
applications are also possible without can-
celling coasting.
– Coasting is not possible in all driving pro-
grams.
