Relling AdBlue

Mercedes-Benz recommends that you top up

AdBlue

at a pump. If no AdBlue

pump is availa-

ble, you can also top up AdBlue

with a canister.

Screw on the fastener of AdBlue

rell canis-

ter

Screw disposable hose 3 onto the opening

of AdBlue

rell canister

4 until hand-tight.

Screw disposable hose 3 onto the ller neck

of the vehicle until hand-tight.

Li up and tip AdBlue

rell canister 4.

The lling process stops when the AdBlue

container is completely full.

AdBlue

rell canister 4 can be removed

when it has been only partially emptied.

Unscrew and close disposable hose 3 and

AdBlue

rell canister

4 in reverse order.

Replace the AdBlue ller cap

2 and turn it

clockwise until it audibly engages.

Close fuel ller ap 1.

Switch on the vehicle for at least 60 seconds.

If it was no longer possible to start the vehicle

due to the empty AdBlue

tank, it takes up to

60 seconds for topping up to be detected.

Start the vehicle.

Avoid storing AdBlue

rell containers perma-

nently in the vehicle.

Charging the high-voltage battery (plug-in

hybrid)

Notes on charging the high-voltage battery

NOTE High-voltage battery damage due to

leaving the vehicle idle for lengthy periods

of time

Lithium-ion batteries experience a natural self-

discharge.

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-

lowing recommendations when handling

the high-voltage battery.

NOTE Accelerated ageing of the high-volt-

age battery due to not observing the fol-

lowing recommendations

As a result of its basic characteristics, the

storage capacity of and the amount of energy

available from the high-voltage battery decrea-

322

Driving and parking

F167 0057 02

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

observe the following recommendations

when handling the high-voltage battery.

NOTE Damage to the drive system when

charging the high-voltage battery at

extreme altitudes

The drive system may be damaged if the high-

voltage battery is charged at elevations

greater than 4,000 m above sea level.

It may then no longer be possible to continue

the journey.

Avoid charging processes at extreme

altitudes.

Recommendations when handling the high-voltage

battery:

Rapid-charge the high-voltage battery with

direct current (Mode 4) only when required.

In case of longer downtimes, switch o the

vehicle with a charge status of the high-volt-

age battery between 25 % and 30 %. Do not

permanently connect the high-voltage battery

to a power supply.

If leaving the vehicle idle for lengthy periods,

avoid high outside temperatures wherever

possible.

Every six weeks check the charge level of the

high-voltage battery (/ page 343).

Make sure to charge the high-voltage battery if

the charge level is below 15 %.

Do not disconnect the 12 V battery even if the

vehicle is le unused for a lengthy period. Oth-

erwise the condition of the vehicle's high-volt-

age battery cannot be monitored.

When only using the high-voltage battery with

low states of charge, fully charge the high-volt-

age battery twice a year.

Depending on the equipment and national ver-

sion, your vehicle is equipped with one of the fol-

lowing vehicle sockets:

Type 1 for charging with alternating current

(mode 2/3)

Type Combo 1 for charging with alternating

current (mode 2/3) and charging with direct

current (mode 4)

Type 2 for charging with alternating current

(mode 2/3)

Type Combo 2 for charging with alternating

current (mode 2/3) and charging with direct

current (mode 4)

Combo 1 vehicle socket Combo 2 vehicle socket

AC charging port type 1 or type 2

Socket extension for DC charging

When using a CCS charging cable (Combined

Charging System) for charging with direct cur-

rent at a vehicle socket type Combo, both

ports on the vehicle socket 1 and 2 are

used for charging.

Charging options for the high-voltage battery

(mode 2, 3 or 4):

While the vehicle is in motion by means of

recuperation

Stationary alternating current charging:

At a mains socket (mode 2)

at a wallbox or charging station (mode 3)

Stationary DC charging (vehicles with vehicle

socket type Combo):

At a rapid-charging station (mode 4)

Depending on the country-specic vehicle equip-

ment and your vehicle's charging cable, single

phase AC charging is also possible.

Observe the dierent grid requirements of your

current location when charging. Only use charging

cables which conform to the grid requirements.

Consult a qualied electrician or your local grid

operator if you have any questions.

It is recommended that you charge the high-volt-

age battery at a wallbox or charging station due to

the improved charging power and better charging

eciency oered.

324

Driving and parking

F167 0057 02

System limits

The power output of the high-voltage battery may

be impaired by the following:

high or low outside temperatures

Electrical auxiliary consumers in the vehicle

being switched on, e.g. operating the air con-

ditioning system

extended periods without charging

The charging time or the charging power of the

high-voltage battery may be increased by the fol-

lowing:

high or low outside temperatures

A low or high charge status of the high-voltage

battery

The maximum available charge current of the

charging device

Stowing the charging cable

Always stow the vehicle's charging cable in the

charging cable bag provided, and secure the

charging cable bag in the boot or load compart-

ment with the included retaining strap. Otherwise,

the charging cable bag with the charging cable is

not suciently secured.

Example: charging cable bag in the boot/load com-

partment

As delivered, charging cable bag 1 with retaining

strap

2 is located in the boot or load compart-

ment. To secure the charging cable bag, the

retaining strap must be attached to tie-down eye

3. Do not use bag hooks to attach the retaining

strap.

Notes on charging the high-voltage battery at a

mains socket (Mode 2)

DANGER Risk of fatal injury from incor-

rectly installed component parts

Connecting the charging cable to a mains

socket using incorrectly installed component

parts could cause a re or an electric shock,

for example.

Only connect the charging cable to a

mains socket that:

Has been properly installed and

Has been inspected by a qualied electri-

cian

For safety reasons, only use the charging

cable supplied with the vehicle or an

original Mercedes‑Benz charging cable.

Purchase these parts at a Mercedes-

Benz Service Centre and obtain advice

there.

Mercedes-Benz thoroughly tests these original

charging cables for their suitability for high-

voltage charging of your vehicle.

Never use a damaged charging cable.

Do not use:

Extension cables

326

Driving and parking

F167 0057 02

The charging process can vary depending on the

power supply equipment. The charging times

when charging the high-voltage battery at the

mains socket are considerably longer than when

charging at a wallbox or charging station.

When doing so, always observe the local informa-

tion.

Do not leave the charging cable controls hanging

loose from a mains socket.

Do not li the controls by the following compo-

nent parts:

When charging, protect the charging cable control

element from excessive heat such as direct sun-

light. Otherwise the charging process may be

aborted.

Notes on charging the high-voltage battery at a

wallbox or charging station (mode 3)

DANGER Risk of fatal injury from incor-

rectly installed component parts

Connecting the charging cable to a wallbox

using incorrectly installed component parts

could cause a re or an electric shock, for

example.

Only connect the charging cable to a

wallbox that:

Has been properly installed and

Has been inspected by a qualied electri-

cian

For safety reasons, only use charging

cables that have been tested and

approved by the manufacturer for charg-

ing the high-voltage battery in an electric

vehicle.

Never use damaged charging cables.

Do not extend the charging cable.

Do not use adapters.

Observe the safety notes in the operat-

ing instructions for the wallbox.

Driving and parking

327

F167 0057 02

Do not use an extension for the charging

cable.

Do not use adapters.

Always observe the safety instructions

on the charging station.

Most charging stations must be activated before

the charging process, e.g. using an RFID card or

via Plug-and-Charge. Observe the on-site opera-

tor's instructions for the charging station and the

notes on Mercedes me Charge (/ page 538).

The amount of energy dispensed for the charging

process, shown by the charging station, may be

higher than the amount of energy actually absor-

bed by the high-voltage battery. This is the result

of dierent levels of charging losses and is descri-

bed as recharge eciency. Charging losses occur,

for example, due to heat that builds up when the

vehicle is charging or from auxiliary consumers

that are switched on. Further information on

recharge eciency can be obtained at a qualied

specialist workshop.

DANGER Risk of death when charging at a

damaged socket

The charging process uses high voltage.

If the charging cable, the vehicle socket or the

mains socket are damaged, you could receive

an electric shock.

Only use an undamaged charging cable.

Avoid mechanical damage such as crush-

ing, abrading or driving over the cable.

Have a damaged vehicle socket replaced

at a qualied specialist workshop as

soon as possible.

Never connect the charging cable to a

damaged vehicle socket.

NOTE Damage due to overheating of

charging cable and charge port

Charging cable and charge port may generate

heat within the permissible limiting values dur-

ing the charging process.

The heat generated by the charging cable and

charge port is inuenced by the following fac-

tors:

The power supply of the mains supply and

the charging cable are intact.

The notes on operating the charging cable

and control element on the charging cable
