Vehicle battery discharge protection
To ensure reliable engine restarts,
several vehicle battery discharge
protection features are implemented
as part of the stop-start system.
Restart of the engine by the
driver
Depress the clutch pedal to restart the
engine.
If the selector lever has been shifted
out of neutral (manual transmission)
or N (manual transmission
automated) or other conditions are
not met, start using the ignition key.
The green control indicator Ï will
extinguish in the instrument cluster
when the engine is restarted.
If the selector lever is shifted out of
neutral (manual transmission) or N
(manual transmission automated) before depressing the clutch first, a
restart will not take place.Restart of the engine by the
stop-start system
The selector lever must be in neutral
(manual transmission) or N (manual
transmission automated) to enable an
automatic restart.
If one of the following conditions
occurs during an Autostop, the
engine will be restarted automatically by the stop-start system. Controlindicator Ï will flash green in the
instrument cluster during an
automatic engine restart.
■ The stop-start system is manually deactivated
■ the bonnet is opened
■ the driver's seat belt is unfastened and the driver's door is opened
■ the engine temperature is too low
■ the vehicle battery is discharged
■ the brake vacuum is not sufficient
■ the vehicle starts to move
■ the defrosting function is activated■ the climate control system requests
an engine start
■ the predetermined timing has been
exceeded
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during restart might be noticeable.
If the Infotainment system is active,
audio sound may briefly be reduced
or interrupted during the restart.
Warning chimes 3 86.
Fault If control indicator Ï illuminates
yellow, there is a fault in the stop-start
system 3 83. A corresponding
message also appears in the Driver
Information Centre 3 84. Seek the
assistance of a workshop.

Vehicle care175Towing another vehicle
Attach a tow rope - or better still a tow
rod - to the rear towing eye, never to
the rear axle and suspension units.
The rear towing eye must only be
used for towing and not recovering a
vehicle.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
Appearance care
Exterior care
Locks
The locks are lubricated at the factory using a high quality lock cylinder
grease. Use de-icing agent only when absolutely necessary, as this has a
degreasing effect and impairs lock
function. After using a de-icing agent,
have the locks regreased by a
workshop.
Washing The paintwork of your vehicle is
exposed to environmental influences.
Wash and wax your vehicle regularly.
When using automatic vehicle
washes, select a programme that
includes waxing. Restrictions for
filmed or matt painted body parts or
decor tapes, see "Polishing and
waxing".Bird droppings, dead insects, resin,
pollen and the like should be cleaned
off immediately, as they contain
aggressive constituents which can
cause paint damage.
If using a vehicle wash, comply with
the vehicle wash manufacturer's
instructions. The windscreen wipers
must be switched off. Remove
antenna and external accessories
such as roof racks etc..
If you wash your vehicle by hand,
make sure that the insides of the
wheel housings are also thoroughly
rinsed out.
Clean edges and folds on opened
doors and the bonnet as well as the
areas they cover.Caution
Always use a cleaning agent with
a pH value of 4 to 9.
Do not use cleaning agents on hot surfaces.
Have the door hinges of all doors
greased by a workshop.
