Problem Possible causes/consequences and
M
MSolutions You have lost the emer-
gency key element. X
Report the loss immediately to the vehicle insurers.
X If necessary, have the locks changed as well. The engine cannot be
started using the key. The on-board voltage is too low.
X
Switch off non-essential consumers, e.g. seat heating or interior
lighting, and try to start the engine again.
If this does not work:
X Check the starter battery and charge it if necessary
(Y page 337).
or
X Jump-start the vehicle (Y page 341).
or
X Consult a qualified specialist workshop. The engine cannot be
started using KEYLESS-
GO. The key is in the
vehicle. A door is open. Therefore, the key cannot be detected as easily.
X
Close the door and try to start the vehicle again. There is interference from a powerful source of radio waves.
X
Start your vehicle with the key in the ignition lock. Doors
Important safety notes
G
WARNING
Only for the United Kingdom: if the vehicle
has been locked with the key, the double lock
function is activated as standard. It is then not
possible to open the doors from inside the
vehicle.
Therefore, do not leave any people behind in
the vehicle, particularly children, elderly peo-
ple or people in need of special assistance if
the vehicle has been locked with the key. As
a result, they may not be able to free them-
selves in the event of an emergency. As a
result, they could be seriously or even fatally
injured by prolonged exposure to extremely
high or low temperatures, for example. In this
case, rescuing people from outside the vehi-
cle is difficult.
Deactivate the interior motion sensor before
you lock the vehicle with the key. The doors can then be opened from the inside after the
vehicle has been locked from the outside with
the key.
G
WARNING
If children are left unsupervised in the vehicle,
they could:
R open a door from inside the vehicle at any
time, even if it has been locked
R start the vehicle using a key which has been
left in the vehicle
R release the parking brake
They could thereby endanger themselves and
others. Never leave children unsupervised in
the vehicle. Always take the key with you
when leaving the vehicle, even if you are only
leaving it for a short time. 82

Problems with the engine
Problem Possible causes/consequences and
M
MSolutions The engine does not
start. The starter motor
can be heard. R
There is a malfunction in the engine electronics.
R There is a malfunction in the fuel supply.
X Turn the key back to position 0in the ignition lock before
attempting to start the engine again.
or
X Press the Start/Stop button repeatedly until all indicator lamps
in the instrument cluster go out.
X Try to start the engine again (Y page 148). Avoid excessively
long and frequent attempts to start the engine, as this will drain
the battery.
If the engine does not start after several attempts:
X Consult a qualified specialist workshop. The engine does not
start. The starter motor
can be heard. The
reserve fuel warning
lamp is lit and the fuel
gauge display shows
0. The fuel tank is empty.
X
Refuel the vehicle. 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.
X
Jump-start the vehicle (Y page 341).
If the engine does not start despite attempts to jump-start it:
X Consult a qualified specialist workshop. The starter motor was exposed to a thermal load that was too high.
X
Allow the starter motor to cool down for approximately two
minutes.
X Try to start the engine again.
If the engine still does not start:
X Consult a qualified specialist workshop. Vehicles with a petrol
engine:
The engine is not run-
ning smoothly and is
misfiring. There is a malfunction in the engine electronics or in a mechanical
component of the engine management system.
X
Only depress the accelerator pedal slightly.
Otherwise, non-combusted fuel may get into the catalytic con-
verter and damage it.
X Have the cause rectified immediately at a qualified specialist
workshop. Driving

!
Only charge the battery using the jump-
start connection point.
The jump-starting connection point is in the
engine compartment (Y page 341).
X Open the bonnet (Y page 313).
X Connect the battery charger to the positive
terminal and earth point in the same order
as when connecting the donor battery in
the jump-starting procedure
(Y page 341).
X Read the battery charger's operating
instructions before charging the battery. 340

Jump-starting
G
WARNING
There is a risk of acid burns when jump-starting a vehicle due to the gases which escape from
the battery. Do not lean over the battery while the engine is being jump-started. G
WARNING
Gases escaping from the battery during jump-starting may cause minor explosions. Avoid cre-
ating sparks. Keep naked flames away from the battery, and do not smoke.
Comply with safety precautions when handling batteries. You will find these under "Battery (vehi-
cle)" in the index. G
WARNING
Non-combusted fuel can collect in the exhaust system and ignite. There is a risk of fire. Avoid
repeated and lengthy starting attempts.
! Vehicles with a petrol engine: avoid repeated and lengthy starting attempts. Otherwise,
the non-combusted fuel may damage the catalytic converter.
Do not use a rapid-charging device to start the vehicle. If your vehicle's battery is discharged,
the engine can be jump-started from another vehicle or from a second battery using jump
leads. Observe the following points:
R the 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.
R vehicles with a petrol engine: only jump-start the vehicle when the engine and exhaust
system are cold.
R do not start the engine if the battery is frozen. Let the battery thaw first.
R jump-starting may only be performed from batteries with a nominal voltage of 12 V.
R only use jump leads that have a sufficient cross-section and insulated terminal clamps.
R if the battery is fully discharged, leave the battery that is being used to jump-start connected
for a few minutes before attempting to start. This charges the empty battery a little.
R make sure that the two vehicles do not touch.
Make sure that:
R the jump leads are not damaged.
R bare parts of the terminal clamp do not come into contact with other metal parts while the
jump leads are connected to the battery.
R the jump leads cannot come into contact with parts such as the V-belt pulley or the fan.
These parts move when the engine is started and while it is running.
X Firmly depress the parking brake.
X Manual transmission: engage neutral.
X Automatic transmission: shift the automatic transmission to position P.
X Switch off all electrical consumers (e.g. radio, blower, etc.).
X Open the bonnet (Y page 313). Jump-starting
