the respective objects. There is risk of fire and
injuries. Hold the cigarette lighter on its handle.
Make sure that children do not use the ciga‐
rette lighter and do not burn themselves, e.g.
by carrying the remote control along when ex‐
iting the vehicle. ◀
CAUTION
If metal objects fall into the socket, they
can cause a short circuit. There is risk of prop‐
erty damage. Replace the cigarette lighter or
socket cover again after using the socket. ◀
Push in the lighter.
The lighter can be removed as
soon as it pops back out.

Information CAUTION
Battery chargers for the vehicle battery
can work with high voltages and currents,
which means that the 12V on-board network
can be overloaded or damaged. There is risk of
property damage. Only connect battery charg‐
ers for the vehicle battery to the starting aid
terminals in the engine compartment. ◀

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 165.
Coasting is automatically activated when
GREEN mode is called via the Driving Dynamics
Control, refer to page 117.
The function is available in a certain speed
range.
A proactively driving style helps the driver to
use the function as often as possible and sup‐
ports 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 168DRIVING TIPSSaving fuel168

3.Check tire inflation pressure at the next op‐
portunity and correct as needed.4.Reinitialize the Flat Tire Monitor, refer to
page 106.
Reinitialize the Tire Pressure Monitor, refer
to page 103.5.Check to make sure the lug bolts are tight
with a calibrated torque wrench.
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, e.g. reduced lane stability when
braking, longer braking distance and changed
self-steering properties in the limit area. There
is risk of an accident. Drive moderately and do
not exceed a speed of 50 mph/80 km/h. ◀
After the trip with emergency wheel
Have the following work performed by a deal‐
er'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.
Vehicle battery
Maintenance
The battery is maintenance-free.
The added amount of acid is sufficient for the
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 risk of property damage. In‐ formation on the compatible 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
dealer’s service center or another qualified
service center or repair shop to ensure that all
comfort features are fully available and that
any Check Control messages of these comfort
features are no longer displayed.
Charging the battery
General information Make sure that the battery is always sufficiently
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 prolonged peri‐
ods, longer than a month.▷Steptronic transmission: when parked for
long periods of time in selector lever posi‐
tion D, R or N.
Information
CAUTION
Battery chargers for the vehicle battery
can work with high voltages and currents, which means that the 12V on-board network
can be overloaded or damaged. There is risk of
property damage. Only connect battery charg‐
ers for the vehicle battery to the starting aid
