apply the parking brake and secure the vehicle
to prevent it from rolling away.
% Depending on the situation, it may take a
shor
t time until j is engaged. Therefore,
always pay attention to the transmission posi-
tion display.
Park position j will be eng
aged automatically if
one of the following conditions is met:
= You switch the stationary vehicle oM in trans-
mission position h or k.
= You open the driver's door when the vehicle is
stationary in transmission position h or k.
= When the vehicle is rolling, you switch if oM in
transmission position h or k and bring it to
a standstill.
= When the vehicle is rolling, you shis to trans-
mission position i, bring the vehicle to a
standstill and open the driver's door when the
vehicle is stationary.
= Engaging park position j automatically is
required by the vehicle. %
To manoeuvre with an open driver's door,
open t

he driver's door while the vehicle is sta-
tionary and engage transmission position h
or k again.

When the automatic transmission is in transmis-
sion position h, it will shis g

This depends, among other things, on the follow-
ing factors:
= The selected drive program
= The position of the accelerator pedal
= The driving speed Problems with the transmission

Y
ou could otherwise fail to recognise
dangers. 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 or
lower gear depending on the steering wheel gear- shis paddle being pulled. You have two options for manually
shising t
he
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 c 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
= Driving style 
To shis up: pull s
teering wheel gearshis pad-
dle 2. 
To shis do

*
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.
= Vehicles with 48 V on-board electrical system:
The combustion engine can be switched oM.
All of the vehicle functions remain active.
Glide mode is activated if the following conditions
are met:
= Drive program  is selected .
= The speed is within a suitable range. =
The r
oad'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.
= You 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.
Glide mode can also be prevented by the following
parameters:
= Incline
= Downhill gradient
= Temperature
= Height
= Speed
= Operating status of the engine
= TraPc situation 170
Driving and parking

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. 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. Driving and parking
171


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. 
Consult a q
ualiNed specialist workshop. *

ted in some countries due to local circum-
stances. For more information, consult a
Mercedes-Benz service centre.
% Vehicles with a diesel engine: R
efuel with at
least 5 litres of diesel if the fuel tank has been
run dry completely.
% Vehicles with a diesel engine: Use a Nller nec
k
with a large diameter for vehicles with a diesel
engine when topping up fuel from a fuel can.
Otherwise, the Nller neck cannot be pushed
into the tank shas. Your vehicle is equipped with an incorrect fuel
pr

otection system to prevent Nlling up with

otes on topping up AdBlue
n
AdBlue n
is a water-soluble Ouid for the NOx
exhaust gas asertreatment of diesel engines. In
order for the exhaust gas asertreatment to func-
tion properly, only use AdBlue n
in accordance
with ISO 22241.
AdBlue n
is characterised by the following:
= non-toxic
= colourless and odourless
= non-Oammable 174
Driving and parking

If you open the AdBlue
n
t ank, small amounts of
ammonia vapour may be released. Only Nll the
AdBlue n
tank in well-ventilated areas.
Do not let AdBlue n
come into contact with skin,
eyes or clothes. Keep AdBlue n
away from chil-
dren.
Do not ingest AdBlue n
. If AdBlue n
is swallowed,
immediately rinse your mouth out thoroughly.
Drink plenty of water. Seek medical attention at
once.
Observe the notes on operating Ouids
(  page 362).
AdBlue n
is available here:
= AdBlue n
can be topped up by fast service at a
qualiNed specialist workshop, e.g. a
Mercedes-Benz Service Centre.
= AdBlue n
is available at many Nlling stations
from AdBlue n
Nlling pumps.
= Alternatively, AdBlue n
is available at qualiNed
specialist workshops, e.g. Mercedes-Benz
Service Centres, and at many Nlling stations in
AdBlue n
reNll canisters or AdBlue n
