Problem
Possible causes/consequences and
M
MSolutions 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 404).
or
X Jump-start the vehicle (Y page 405).
or
X Consult aqualified specialist workshop. Only for vehicles with
manual transmission:
The engine cannot be
started using the key. The steering lock is mechanically blocked.
X Remove the key and reinsert it into the ignition lock. While doing
this, turn the steering wheel in both directions. The engine cannot be
started using KEYLESS-
GO. The key is in the
vehicle. The vehicle is locked.
X Unlock the vehicle and try to start the vehicle again. There is interference from
apowerful source of radio waves.
X Start your vehicle with the key in the ignition lock. Doors
Important safety notes
United Kingdom only: G
WARNING
When the double locks are activated, the
doors can no longer be opened from the
inside. People in the vehicle can no longer get out, e.g. in hazardous situations. There is a
risk of injury.
Therefore, do not leave any people unsuper-
vised in the vehicle, particularly children, eld-
erly people or people in need of special assis-
tance. Do not activate the double lock when
people are in the vehicle.
If the vehicle has been locked from the out-
side, the double lock function is activated as
standard. It is then not possible to open the
doors from inside the vehicle. You can deac- tivate the double lock function by deactivat-
ing the interior motion sensor (Y page 91).
The doors can then be opened from the inside after the vehicle has been locked from the
outside.
The anti-theft alarm system is triggered if thedoor is opened from the inside. Switch off the
alarm (Y page 89).
All countries: G
WARNING
If children are left unsupervised in the vehicle, they could:
R open doors, thereby endangering other per-
sons or road users
R get out and be struck by oncomingt raffic
R operate vehicle equipment and become
trapped, for example 100

Possible causes/consequences and
M
MSolutions The engine does not
start. The HOLD function or DISTRONIC PLUS is activated.
X Deactivat ethe HOLD function (Y page 228) or DISTRONIC
PLUS (Y page 224).
X Try to start the engine again. The engine does not
start. The starter motor
can be heard. R
There is amalfunction in the engine electronics.
R There is amalfunction in the fuel supply.
Before attempting to start the engine again:
X Turn the key back to position 0in the ignition lock.
or
X Press the Start/Stop button repeatedly until all indicator lamps
in the instrumen tcluster go out.
X Try to start the engine again (Y page 181). Avoid excessively
long and frequent attemptstos tart the engine, as this will drain
the battery.
If the engine does not start after several attempts: X Consult aqualified 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 405).
If the engine does not start despite attemptstoj ump-start it:
X Consult aqualified specialist workshop. The starter motor was exposed to
athermal 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 aqualified specialist workshop. Driving

safety-relevant systems, e.g the lighting sys-
tem ,the AB S(anti-loc kbraking system) or the
ESP ®
(Electronic Stability Program). The oper-
atin gsafet yofy our vehicle may be restricted.
You could lose control of the vehicle, for
example:
R when braking
R in the even tofabrupt steerin gmanoeuvres
and/or when the vehicle's speed is not
adapted to the road conditions
There is arisk of an accident.
In the even tofashortcircuit or asimilar inci-
dent ,contac taqualified specialist workshop
immediately. Do not drive any further. Always have work on the battery carried out at a
qualified specialist workshop.

WARNING
Electrostatic build-up can lead to the creation of sparks, which could ignit ethe highly explo-
sive gases of abattery. There is arisk of an
explosion.
Before handlin gthe battery, touc hthe vehicle
body to remove any existin gelectrostatic
build-up.
The highly flammable gas mixture is created
while the battery is charging and when jump-
starting.
Always make sure that neither you nor the
battery is electrostatically charged. Electro-
static charge is created, for example:
R by wearing synthetic fibre clothing
R due to friction betwee nclothing and the
seat
R when you pull or push the battery across
carpe torother synthetic materials
R when you rub the battery with acloth G
WARNING
Durin gthe charging process, abattery produ-
ces hydroge ngas. If ashor tcircuit occurs or spark
sare created, the hydroge ngas can
ignite. There is arisk of an explosion.
R Make sure that the positive terminal of a
connected battery does not com eintoc on-
tac twith vehicle parts.
R Never place metal object sortools on abat-
tery.
R It is importan tthat you observe the descri-
bed order of the battery terminals when
connectin gand disconnecting abattery.
R When jump-starting, make sure that the
battery poles with identical polarit yare
connected.
R It is particularly importan ttoobserve the
described order when connectin gand dis-
connectin gthe jump leads.
R Never connec tordisconnect the battery
terminals while the engin eisrunning. G
WARNING
Batter yacid is caustic. There is arisk of injury.
Avoid contac twith the skin ,eyes or clothing.
Do not breathe in any battery gases. Do not
lean over the battery. Keep the batteries out
of the reach of children. Immediately rinse off
battery acid thoroughly with plent yofclean
water and seek medical attention at once. H
Environmental note Batteries contain pollutants.
It is illegal to dispose of them
with the household rubbish.
They must be collected sep-
arately and dispose dofinan
