when unfolding. There is risk of injuries. make
sure that devices and cables are not in the air‐
bag's area of unfolding. ◀
CAUTION
Battery chargers for the vehicle battery
can work with high voltages and currents,
which means that the 12 volt on-board net‐
work can be overloaded or damaged. There is
risk of property damage. Only connect battery
chargers for the vehicle battery to the starting
aid terminals in the engine compartment. ◀Seite 149Interior equipmentCONTROLS149

Coasting
The concept The system helps to conserve fuel.
To do this, under certain conditions the engine
is automatically decoupled from the transmis‐ sion when selector lever position D is set. The
vehicle continues traveling with the engine
idling to reduce fuel consumption. Selector
lever position D remains engaged.
This driving condition is referred to as coasting.
As soon as the brake or accelerator pedal is de‐
pressed, the engine is automatically coupled to
the transmission again.
Information
Coasting is a component of the GREEN driving
mode, refer to page 167.
Coasting is automatically activated when
GREEN Mode is called via the Driving Dynamics
Control, refer to page 118.
The function is available in a certain speed
range.
A proactive driving style helps the driver to use
the function as often as possible and supports
the fuel-conserving effect of coasting.
Safety mode
The function is not available under one of the
following conditions.▷DSC OFF or TRACTION activated.▷Driving in the dynamic limit range and on
steep uphill or downhill grades.▷Battery charge status temporarily too low
or vehicle electrical system drawing exces‐
sive current.▷Cruise control activated.
Functional requirements
In GREEN Mode, this function is available in a
speed range from approximately 30 mph, ap‐
prox. 50 km/h to 100 mph, approx. 160 km/h,
if the following conditions are met:
▷Accelerator pedal and brake pedal are not
operated.▷The selector lever is in selector lever posi‐
tion D.▷Engine and transmission are at operating
temperature.Seite 170DRIVING TIPSSaving fuel170

Driving with emergency wheel
WARNING
The emergency wheel has particular di‐
mensions. When driving with an emergency wheel, changed driving properties may occur at
higher speeds, for example reduced lane stabil‐
ity when braking, longer braking distance and
changed self-steering properties in the limit
area. There is risk of an accident. Drive moder‐
ately and do not exceed a speed of
50 mph/80 km/h. ◀
After the trip with emergency wheel Have the following work performed only by a
dealer's service center or another qualified
service center or repair shop.
1.Replace the damaged tires as soon as pos‐
sible.2.Replace the emergency wheel with a new
wheel.3.Have the tray with the emergency wheel
installed.

service life of the battery.
More information about the battery can be re‐
quested from a dealer’s service center or an‐
other qualified service center or repair shop.
Battery replacement CAUTION
Vehicle batteries that are not compatible
can damage vehicle systems and impair vehicle
functions. There is a risk of personal and prop‐
erty damage. Only vehicle batteries that are
compatible with your vehicle type should be in‐
stalled in your vehicle. Information on compati‐
ble vehicle batteries is available at your dealer’s
service center. ◀
After a battery replacement, the manufacturer
of your vehicle recommends that the vehicle
battery be registered on the vehicle by a

charged to guarantee that the battery remains
usable for its full service life.
The battery may need to be charged in the fol‐
lowing cases:▷When making frequent short-distance
drives.▷If the vehicle is not used for more than a
month.▷Steptronic transmission: when parked for
long periods of time in selector lever posi‐
tion D, R or N.Seite 214MOBILITYReplacing components214
