Problem Possible causes/consequences and
M Solutions
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 325).
or
X Jump-start the vehicle (Y page 329).
or
X Consult a qualified specialist workshop. 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. Ad
oor 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 akey 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. Doors

accelerate or brake suddenly. You will then
no tb e able to brake, declutch or accelerate
as intended. This could lead to accidents and
injury. G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. This could cause you
to lose control of your vehicle and cause an
accident.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only set the automatic transmission to the
respective drive positions when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. Otherwise, you could damage the
drive train.
! AMG vehicles: at low engine oil tempera-
tures (below +20 †), the maximum engine
speed is restricted in order to protec tthe
engine. To protect the engine and maintain
smooth engine operation, avoid driving at
full throttle when the engine is cold. Key positions
Key g
To remove the key
1 Power supply for some consumers, such
as the windscreen wipers
2 Ignition (power supply for all consumers)
and drive position
3 To start the engine
If the key is at position 0in the ignition lock
for a longer period, it can no longer be turned
in the ignition lock. The steering is then
locked. To unlock it, remove the key and rein-
sert it into the ignition lock.
The steering wheel is locked when the key is
removed from the ignition lock.
i If the key does not belong to the vehicle
it can still be turned in the ignition lock.
However, the ignition will not be switched
on The engine cannot be started.
KEYLESS-GO General notes
Vehicles with KEYLESS-GO are equipped with
a key featuring an integrated KEYLESS-GO
function and a detachable Start/Stop button.
The Start/Stop button must be inserted into
the ignition lock and the key must be in the
vehicle.
Pressing the Start/Stop button several times
in succession corresponds to the different
key positions in the ignition lock. This is only
the case if you are not depressing the brake
pedal. Driving

Important safety notes
G
WARNING
Only remove the key from the ignition lock
when the vehicle is stationary, as you cannot
steer the vehicle when the key is removed.
Never leave children unsupervised in the vehi-
cle. They could release the parking brake. This
could lead to a serious or fatal accident. G
WARNING
Under no circumstances should the exhaust
system come into contact with flammable
materials such as dry grass or petrol, for
example. Do not park the vehicle on dry grass-
land or harvested grain fields. The hot exhaust
system could otherwise ignite the flammable
material and set the vehicle on fire.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the parking brake must be applied.
R on vehicles with manual transmission,
engage first gear or reverse gear.
R on vehicles with automatic transmission,
the transmission must be in position Pand
the key must be removed from the ignition
lock.
R on steep uphill or downhill gradients, turn
the front wheels towards the kerb. Switching off the engine
Important safety notes G
WARNING
If the engine is not running, there is no power
assistance for the steering and brakes. Steer-
ing and braking then requires significantly
greater effort.
As a result, you might lose control of the vehi-
cle, cause an accident and injure yourself and
others. Therefore, do not switch off the engine while
you are driving.
Vehicles with manual transmission X

The engine stops and all the indicator
lamps in the instrumen tcluste rgo out.
i When the driver's door is closed, this cor-
responds to key position 1. When the driv-
er's door is open, this corresponds to key
position 0, i.e. key removed.
i The engine can be turned off while the
vehicle is in motion by pressing and holding
the Start/Stop button for three seconds.
This function operates independently of the
ECO start/stop automatic engine switch-
off function. 158

connect it to a trickle charger.
i You can obtain information about trickle
chargers from a qualified specialist work-
shop, e.g. a Mercedes-Benz Service
Centre.
If you leave the vehicle parked up for longer
than six weeks, the vehicle may suffer dam-
age as a result of lack of use.
X Visit a qualified specialist workshop and
seek advice. Driving tips
General driving tips
Rolling with the engine switched off G
WARNING
Never switch the engine off while the vehicle
is in motion.
There is no power assistance for the steering
and the service brake when the engine is not
running.
You will require considerably more effort to
steer and brake, and you could therefore lose
control of the vehicle and cause an accident. Engine oil
! Vehicles with adiesel particle filter:
If the vehicle is mostly driven for short dis-
tances, it is possible that malfunctions may
occur during the automatic cleaning of the
diesel particle filter. This can lead to engine
damage. Therefore, if you frequently drive
short distances, make sure to drive on
motorways or country roads for 20 minutes
at least every 500 km. Brakes
Important safety notes G
WARNING
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
Make sure that other road users are not
endangered by your braking.
Downhill gradients On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer,
you must shift to a lower gear in good time or, Driving tips
159Driving and parking Z

R
is affected more by strong crosswinds
R demands more sensitive steering
R consumes more fuel
On long and steep downhill gradients, you
must shift to a lower gear in good time, or on
vehicles with automatic transmission, select
the shift range 1,2or 3.
i This also applies if you have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to maintain
the speed. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously.
Driving tips R
Maintain a greater distanc efrom the vehi-
cle in front than when driving without a
trailer.
R Avoid braking abruptly .Ifpossible, brake
gently at first to allow the trailer to run on.
Then, increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from a standstill refer to sea
level. When driving in mountainous areas,
note that the power output of the engine,
and consequently the vehicle's gradient-
climbing capability, decrease with increas-
ing altitude.
If the trailer swings from side to side:
X Do not accelerate.
X Do not counter-steer.
X Brake if necessary. Folding out the ball coupling
Before you can tow a trailer with your vehicle,
you must fold out the ball coupling.
The release wheel is located behind the left-
hand side trim panel in the boot. G
WARNING
Make sure that the ball coupling is engaged,
either in its folded-out or folded-in position,
and that the indicator lamp is off.
Do not turn the release wheel when a trailer
is coupled up. Otherwise, the trailer might
detach. X
