Problems with the engine
ProblemPossible causes/consequences andMSolutions
The engine does not
start. The starter motor
can be heard.RThere isamalfunction in the engine electronics.
RThere is amalfunction in the fuel supply.
Before attempting to start the engine again:
XTurn the SmartKey back to position 0in the ignition lock.
or
XPress the Start/Stop button repeatedly until all indicator lamps in
the instrumentc luster go out.
XTry to start the engine again (Ypage 133). Avoid excessively long
and frequent attemptstos tart the engine as these will drain the
battery.
If the engine does not start after several attempts:
XConsult aqualified specialist workshop.
The engine does not
start. You cannot hear
the starter motor.The on-board voltage is too low because the battery is too weak or
discharged.
XJump-start the vehicle (Ypage 308).
If the engine does not start despite attempt stojump-start it:
XConsult aqualified specialist workshop.
The starter motor was exposed to athermal load that was too high.
XTry to start the engine again (Ypage 133).
If the engine still does not start:
XConsult aqualified specialist workshop.
The engine is not running
smoothly and is misfir-
ing.There is amalfunction in the engine electronics or in amechanical
componentoft he engine management system.
XOnly depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it.
XHave the cause rectified immediately at aqualified specialist work-
shop.
The coolant temperature
gauge shows avalue
above 248 ‡(120 †).The coolant level is too low. The coolant is too hot and the engine is no
longer being cooled sufficiently.
XStop as soon as possible and allow the engine and the coolant to
cool down.
XCheck the coolant level (Ypage 290). Observe the warning notes
as you do so and add coolant if necessary.

Battery (vehicle)
12 Vb attery –important safety notes
Special tools and expert knowledge are required
when working on the battery, e.g. removal and
installation .You should therefore have all work
involvin gthe battery carried out at aqualified
specialist workshop.
GWARNING
Work carried out incorrectly on the battery
can lead, for example, to ashort circuit and
thus damage the vehicle electronics. This can
lead to function restriction sapplying to
safety-relevant systems, e.g the lighting sys-
tem, the ABS (anti-loc kbraking system) or the
ESP
®(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example:
Rwhen braking
Rin the event of abrupt steerin gmaneuvers
and/or when the vehicle's speed is not
adapted to the road conditions
There is arisk of an accident.
In the event of ashort circuit or asimilar inci-
dent, contact aqualified specialist workshop
immediately. Do not drive any further .You
should have all work involvin gthe battery car-
ried out at aqualified specialist workshop.
For further information about ABS and ESP
®,
see (Ypage 62) and (Ypage 67).
All vehicles except vehicles with alithium-
ion battery:
GWARNING
Electrostatic build-up can lead to the creation of sparks, which could ignite the highly explo-
sive gases of abattery. There is arisk of an
explosion.
Before handling the battery, touch the vehicle
body to remove any existin gelectrostatic
build-up.
The highly flammable gas mixture forms when
charging the battery as well as when jump-start-
ing.
Always make sure that neither you nor the bat-
tery is electrostatically charged. Abuild-up of
electrostatic charge can be caused, for exam-
ple:
Rby wearing clothin gmade from synthetic
fibers
Rdue to friction between clothin gand seats
Rif you push or pull the battery across the car-
pet or other synthetic materials
Rif you wipe the battery with acloth
GWARNING
During the charging process, abattery produ-
ces hydrogen gas. If ashort circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is arisk of an explosion.
RMake sure that the positive terminal of a
connected battery does not come into con-
tact with vehicle parts.
RNever place metal object sortools on abat-
tery.
RIt is importan tthat you observe the descri-
bed order of the battery terminals when
connectin gand disconnectin gabattery.
RWhen jump-starting, make sure that the
battery poles with identical polarity are
connected.
RIt is particularly importan ttoobserve the
described order when connectin gand dis-
connectin gthe jumper cables.
RNever connect or disconnect the battery
terminals while the engine is running.
GWARNING
Battery acid is caustic. There is arisk of injury.

Jump-starting
For the jump-starting procedure, use only the jump-starting connection point in the engine com-
partment,consisting of apositive terminal and aground point.
All vehiclese xcept vehiclesw ithalithium-ion battery:
GWARNING
Battery acid is caustic. There is arisk 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 arisk
of an explosion.
Particularly avoid fire, open flames, creating sparks and smoking. Ensure there is sufficient ven-
tilation while charging and jump-starting. Do not lean over abattery.
GWARNING
During the charging process, abattery produces hydrogen gas. If ashort circuit occurs or sparks
are created, the hydrogen gas can ignite. There is arisk of an explosion.
RMake sure that the positive terminal of aconnected battery does not come into contact with
vehicle parts.
RNever place metal objects or tools on abattery.
RIt is important that you observe the described order of the battery terminals when connecting
and disconnecting abattery.
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 disconnectt he battery terminals while the engine is running.
GWARNING
Ad ischarged 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 arisk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
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.Int his case, you may neither charge the
battery nor jump-start the vehicle. The service life of athawed-out battery may be shorter. The
starting characteristicsc an be impaired, particularly at low temperatures. Have the thawed-out
battery checked at aqualified specialist workshop.
All vehicles:
!Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.
