Information about Service
Resetting the service display
!Have service work carried out as descri-
bed in the Maintenance Booklet. This may
otherwise lead to increased wear and dam-
age to the major assemblies or the vehicle.
A qualified specialist workshop, e.g. a smart center, will reset the service interval dis-
play after the service work has been carried
out. You can also obtain further information
on maintenance work, for example.
Special service requirements
The prescribed service interval is based on
normal operation of the vehicle. Service work
will need to be performed more often if the
vehicle is operated under arduous conditions
or increased loads, for example:
Rregular city driving with frequent inter-
mediate stops
Rif the vehicle is primarily used to travel
short distances
Rfor frequent operation in mountainous ter-
rain or on poor road surfaces
Rif the engine is often left idling for long
periods
In these or similar operating conditions,
have, for example, the air filter, engine oil
and oil filter changed more frequently. The
tires must be checked more frequently if the
vehicle is operated under increased loads.
You can obtain further information at a
qualified specialist workshop, e.g. a smart
center.
Driving abroad
An extensive smart service network is also
available in other countries. For further
information inquire at any smart center.

>> Breakdown assistance.

Always make sure that neither you nor the bat-
tery is electrostatically charged. There is a
build-up of electrostatic charge, e.g.:
Rby wearing clothing made from synthetic
fibers
Rdue to friction between clothing and seats
Rif you push or pull the battery across the
carpet or other synthetic materials
Rif you wipe the battery with a cloth.
GWARNING
During the charging process, a battery pro-
duces hydrogen gas. If a short circuit
occurs or sparks are created, the hydrogen
gas can ignite. There is a risk of an explo- sion.
RMake sure that the positive terminal of a
connected battery does not come into
contact with vehicle parts.
RNever place metal objects or tools on a
battery.
RIt is important that you observe the
described order of the battery terminals
when connecting and disconnecting a
battery.
RWhen jump-starting, make sure that the
battery poles with identical polarity are
connected.
RIt is particularly important to observe
the described order when connecting and
disconnecting the jumper cables.
RNever connect or disconnect the battery
terminals while the engine is running.
GWARNING
Battery acid is caustic. There is a risk of
injury.
Avoid contact with skin, eyes or clothing.
Do not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash away battery acid immedi-
ately with plenty of clean water and seek
medical attention.
HEnvironmental note
Batteries contain danger-
ous substances. It is
against the law to dispose
of them with the household
rubbish. They must be col-
lected separately and recy-
cled to protect the envi-
ronment.
Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to a qualified
specialist workshop or a
special collection point
for used batteries.
!Have the battery checked regularly at a
qualified specialist workshop.
Observe the service intervals in the Main-
tenance Booklet or contact a qualified spe-
cialist workshop for more information.
!You should have all work involving the
battery carried out at a qualified special-
ist workshop. In the exceptional case that
it is necessary for you to disconnect the
battery yourself, make sure that:
Ryou switch off the engine and remove the
SmartKey. Check that all the indicator
lamps in the instrument cluster are off.
Otherwise, electronic components, such
as the alternator, may be damaged.
Ryou first remove the negative terminal
clamp and then the positive terminal
clamp. Never swap the terminal clamps.
Otherwise, the vehicle's electronic sys-
tem may be damaged.
The battery and the cover of the positive
terminal clamp must be installed securely
during operation.

Jump-starting
GWARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with skin, eyes or clothing. Do not inhale any battery gases. Do not lean over
the battery. Keep children away from batteries. Wash away battery acid immediately with
plenty of clean water and seek medical attention.
GWARNING
During charging and jump-starting, explosive gases can escape from the battery. There is a
risk of an explosion.
Particularly avoid fire, open flames, creating sparks and smoking. Ensure there is suffi-
cient ventilation while charging and jump-starting. Do not lean over a battery.
GWARNING
During the charging process, a battery produces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can ignite. There is a risk of an explosion.
RMake sure that the positive terminal of a connected battery does not come into contact with
vehicle parts.
RNever place metal objects or tools on a battery.
RIt is important that you observe the described order of the battery terminals when con-
necting and disconnecting a battery.
RWhen jump-starting, make sure that the battery poles with identical polarity are con-
nected.
RIt is particularly important to observe the described order when connecting and dis-
connecting the jumper cables.
RNever connect or disconnect the battery terminals while the engine is running.
GWARNING
A discharged battery can freeze at temperatures below freezing point. When jump-starting
the vehicle or charging the battery, gases can escape from the battery. There is a risk of an
explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
!Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.
If, at low temperatures, the indicator lamps/warning lamps in the instrument cluster do not
light up, it is highly likely that the discharged battery has frozen. In this case you may neither
jump-start the vehicle nor charge the battery. The service life of a thawed-out battery may be
shorter. The starting characteristics can be impaired, particularly at low temperatures. Have
the thawed-out battery checked at a qualified specialist workshop.
168Jump-starting
>> Breakdown assistance.

Do not start the vehicle using a rapid charging device. If your vehicle's battery is discharged,
the engine can be jump-started from another vehicle or from a second battery using jumper
cables. Observe the following points:
RThe battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,
jump-start the vehicle using a second battery or a jump-starting device.
RYou may only jump-start the vehicle when the engine and exhaust system are cold.
RDo not start the engine if the battery is frozen. Let the battery thaw first.
ROnly jump-start from batteries with a 12 V voltage rating.
ROnly use jumper cables which have a sufficient cross-section and insulated terminal
clamps.
RIf the battery is fully discharged, leave the battery that is being used to jump-start con-
nected for a few minutes before attempting to start. This charges the battery slightly.
RMake sure that the two vehicles do not touch.
Make sure that:
RThe jumper cables are not damaged.
RBare parts of the terminal clamp do not come into contact with other metal parts while the
jumper cables are connected to the battery.
RThe jump leads cannot come into contact with parts which can move when the engine is
running, such as the wiper rods or the fan.
