Problems with the transmission
The transmission has a faulty gear
shis
P ossible cause:
= the transmission is losing oil. 
Have the transmission checked at a q
ualiNed
specialist workshop immediately.
The acceleration characteristics get worse, and
t
he transmission no longer shiss.
Possible cause:
= the transmission is in emergency operation
mode. 
Stop the vehicle in accordance with the tr
aPc
conditions. 
Shis t
he transmission to position j.
Switch oM t
he vehicle. 
Wait at least ten seconds. 
Start the vehicle again. 
Shis t

egarding the regenerative brake system
(  page 176). When the automatic transmission is
shised t
o
position h, you can manually shis it with the
steering wheel gearshis paddle. If permitted, the
automatic transmission will shis to a higher orlower gear depending on the steering wheel gear-
shis paddle being pulled.
Y

ou have two options for manually shising the
automatic transmission:
= Temporary setting
= Permanent setting
The gears will shis automatically when manual
shising is deactivated.
Temporary setting: 
To activate: pull s
teering wheel gearshis pad-
dle 1 or 2.
Manual shising will be activated for a short
time. The transmission position display will
show p and the current gear.
% How long manual shising s
tays activated
depends on various factors.
Manual shising can be deactivated automati-
cally in the following cases:
= When the drive program is changed
= When the vehicle is restarted
= When transmission position h is engaged
again 188

*
NOTE Mer
cedes-AMG vehicles 
Observe the notes in the Supplement.
Y
ou could otherwise fail to recognise
dangers. With an anticipatory driving style, Glide mode
helps y

ou to reduce fuel consumption.
Glide mode is characterised by the following: = The combustion engine is disconnected from
the drivetrain and continues to run in neutral.
= The transmission position display h is shown
in green.
Glide mode is activated if the following conditions
are met:
= Drive program  is selected .
= The speed is within a suitable range.
= The road's course is suitable, e.g. no steep
uphill or downhill inclines or tight bends.
= There is no trailer hitched up to the trailer
hitch, and no bicycle rack Ntted. Driving and parking
189

=
Y ou do not depress the accelerator or brake
pedal (except for light brake applications).
% Glide mode can also be activated if you have
select
ed the "Eco" setting for the drive in the
drive program .
Glide mode will be deactivated again if one of the
conditions is no long
er met.
Vehicles with Active Distance Assist DISTRONIC:
When Active Distance Assist DISTRONIC is active,
the glide mode function will not be available.
Glide mode can also be prevented by the following
parameters:
= Incline
= Downhill gradient
= Temperature
= Height
= Speed
= Operating status of the engine
= TraPc situation
% You can end glide mode by operating a steer-
ing wheel g

earshis paddle ( page 188). Function of 4MATIC
4MA
TIC ensures that all four wheels are driven.
Together with ESP n
and 4ETS, 4MATIC improves
the traction of your vehicle whenever a driven
wheel spins due to insuPcient traction.
If you fail to adapt your driving style, 4MATIC can
neither reduce the risk of an accident nor override
the laws of physics. 4MATIC cannot take account
of road, weather and traPc conditions. 4MATIC is
only an aid. You are responsible especially for
maintaining a safe distance from the vehicle in
front, for vehicle speed, for braking in good time
and for staying in lane.
% In wintry road conditions, the maximum eMect
of 4MA
TIC can be achieved only if you use
winter tyres (M+S tyres), with snow chains if
necessary. Refuelling

&
WARNING Risk of Nr
e or explosion from
fuel
Fuels are highly Oammable. 
Fire, naked Oames, smoking and cr
eating
sparks must be avoided. 
Before refuelling, switch oM t
he vehicle
and, if Ntted, the stationary heater and
keep switched oM during Nlling. &
WARNING Risk of injur
y from fuels
Fuels are poisonous and hazardous to your
healt
h. 
Do not swallow fuel or let it come into
cont

act with skin, eyes or clothing. 
Do not inhale fuel vapour. 
Keep children away from fuel. 
Keep doors and windows closed during
t

he refuelling process. 190
Driving and parking

If you or other people come into contact with
fuel, obser
ve the following: 
Immediately rinse fuel oM y
our skin with
soap and water. 
If fuel comes into contact with your eyes,
immediat
ely rinse them thoroughly with
clean water. Seek medical attention
immediately. 
If you swallow fuel, seek medical atten-
tion immediat

ely. Do not induce vomit-
ing. 
Change immediately out of clothing that
has come int
o contact with fuel. &
WARNING Risk of Nr
e and explosion due
to electrostatic charge
Electrostatic charge can ignite fuel vapour. 
Before you open the fuel Nller cap or
t
ake hold of the pump nozzle, touch the
metallic vehicle body. 
To avoid creating another electrostatic
c

harge, do not get into the vehicle again
during the refuelling process. &
WARNING Risk of Nr
e from fuel mixture
Vehicles with a diesel engine:
If y
ou mix diesel fuel with petrol, the Oash
point of the fuel mixture is lower than that of
pure diesel fuel.
While the vehicle is running, component parts
in the exhaust system may overheat without
warning. 
Never refuel using petrol. 
Never mix petrol with diesel fuel. *
NOTE Damag
e caused by the wrong fuel Vehicles with a petrol engine:
Ev

en small amounts of the wrong fuel could
result in damage to the fuel system, the
engine and the emission control system. 
Only refuel using unleaded, sulphur-free
spar
k-ignition engine fuel that conforms to European EN 228, or an equivalent
speciNcation.
Fuel of this speciNcation ma
y contain up to
10% ethanol. Your vehicle is suitable for use
with E10 fuel.
Never refuel with one of the following fuels:
= Diesel
= Regular petrol with an octane number
lower than 91 RON
= Petrol with more than 10% ethanol by vol-
ume, e.g. E15, E20, E85, E100
= Petrol with more than 3% methanol by vol-
ume, e.g. M15, M30
= Petrol with additives containing metal
If you have accidentally refuelled with the
wrong fuel: 
Do not switch on the vehicle.

h
ybrid) Notes on charging the high-voltage battery
*
NOTE High-v
oltage battery damage due to
leaving the vehicle idle for lengthy periods
of time Lithium-ion batteries experience a natural self-
disc
harge.
Exhaustive discharging can therefore occur if
the vehicle is idle for several months. This can
damage the high-voltage battery. 
To avoid damage, please observe the fol-
lo

wing recommendations when handling
the high-voltage battery. *
NOTE A
ccelerated ageing of the high-volt-
age battery due to not observing the fol-
lowing recommendations As a result of its basic characteristics, the
s
torage capacity of and the amount of energy
available from the high-voltage battery decrea-
ses over the course of its life. Due to this, both
the maximum electrical range that can be ach-
ieved by the vehicle and its maximum electri-
cal output can be impaired.
The following factors could accelerate the age-
ing of the high-voltage battery:
= a high level of charge, especially if the
vehicle is idle for a lengthy period of time
= frequent rapid charging with direct current
(mode 4)
= leaving the vehicle idle for lengthy periods
at high ambient temperatures 
To avoid accelerated ageing, please
obser
ve the following recommendations
when handling the high-voltage battery. Driving and parking
