MERCEDES-BENZ GLE COUPE 2022 Owners Manual


During starting assistance, always take
car
e to connect only battery terminals of
identical polarity. 
During starting assistance, observe the
seq
uence described for connecting and
disconnecting the jump leads. 
Do not connect or disconnect the bat-
t

ery terminals with the engine running. &
WARNING Risk of e
xplosion due to explo-
sive mixture of gases
An explosive mixture of gases can escape
fr
om the battery during charging and starting
assistance. 
Fire, naked Oames, smoking and cr
eating
sparks must be avoided. 
Make sure there is adequate ventilation. 
Do not stand over the battery. &
WARNING Risk of e
xplosion from a frozen
battery
A discharged battery may freeze at tempera-
tur
es slightly above or below freezing point.
During starting assistance or battery charging,
battery gas can be released. 
Always allow a battery to thaw before
c
harging it or performing starting assis-
tance. If the indicator/warning lamps in the instrument
clus
ter do not light up at low temperatures, it is
very likely that the discharged battery has frozen.
In this case you may neither jump-start the vehi-
cle nor charge the battery.
The service life of a battery that has been thawed
may be dramatically shortened. The starting char-
acteristics may be impaired, especially at low
temperatures.
It is recommended that you have a thawed battery
checked at a qualiNed specialist workshop. Plug-in hybrid
If y

our vehicle has been started with starting
assistance, it may not be possible to use the elec-
tric drive for approximately 30 minutes.
Starting assistance is not considered to be a nor-
mal operating condition.
All vehicles
* NOTE Damag
e caused by numerous or
extended attempts to start the engine Numerous or extended attempts to start the
engine ma

y damage the catalytic converter
due to non-combusted fuel. 
Avoid numerous and extended attempts
t

o start the engine. Observe the following points during starting assis-
t
ance and when charging the battery:
= Only use undamaged jump lead/charging
cables with a suPcient cross-section and
insulated terminal clamps.
= Non-insulated parts of the terminal clamps
must not come into contact with other metal 398

parts while the jump lead/charging cable is
connect
ed to the battery/jump-start connec-
tion point.
= The jump lead/charging cable must not come
into contact with any parts which may move
when the engine is running.
= Always make sure that neither you nor the bat-
tery is electrostatically charged.
= Keep away from Nre and naked Oames.
= Do not lean over the battery.
Observe the additional following points when
charging the battery: = Only use battery chargers tested and
approved for Mercedes-Benz.
= Read the battery charger's operating instruc-
tions before charging the battery.
Observe the additional following points during
starting assistance:
= Starting assistance may only be provided
using vehicles, batteries or other jump start
devices with a nominal voltage of 12 V.
= The vehicles must not touch. =
V ehicles with a petrol engine: jump-start the
vehicle only when the engine and exhaust sys-
tem are cold. Starting assistance and charging the 12 V battery
Requirements:
= The v

ehicle is secured with the electric park-
ing brake.
= Vehicles with automatic transmission: the
transmission is in position j.
= The vehicle and all electrical consumers are
switched oM.
= The bonnet is open. Example: engine compartment

begin with POSITIVE contact
2 on y our own
vehicle Nrst. 
During starting assistance: s
tart the engine of
the donor vehicle and run at idle speed. 
Connect the negative terminal of the donor
batt

ery and earth point 3 of your own vehicle
by using the jump lead/charging cable. Begin
with the donor battery Nrst.
During starting assistance: s
tart the engine of
your own vehicle. 
During the charging process: s

ing process. 
During starting assistance: le
t the engines run
for several minutes. 
During starting assistance: bef
ore disconnect-
ing the jump lead, switch on an electrical con-
sumer on your own vehicle, e.g. the rear win-
dow heater or lighting.
When the starting assistance/charging process is
com
plete, perform the following steps: 
First, remove the jump lead/charging cable
fr
om earth point 3 and the negative terminal of the donor battery, then POSITIVE contact
2 and t

he positive terminal of the donor bat-
tery. Begin each time with the contacts on
your own vehicle Nrst. 
Aser r
emoving the jump lead/charging cable,
close cover 1 of POSITIVE contact 2.
Plug-in hybrid: if y
our vehicle has been started
with starting assistance, it may not be possible to
use the electric drive for approximately 30
minutes.
Further information can be obtained at a qualiNed
specialist workshop. Replacing the 12 V battery

Observe the notes on the 12 V battery
( pag
e 395).
Mercedes-Benz recommends that you have the
12 V batt
ery replaced at a qualiNed specialist
workshop, e.g. at a Mercedes-Benz Service
Centre. Observe the following notes if you want to replace
t

he battery yourself:
= Always replace a faulty battery with a battery
which meets the speciNc vehicle require-
ments.
The vehicle is equipped with an AGM technol-
ogy battery (Absorbent Glass Mat) or a lith-
ium-ion battery. Full vehicle functionality is
only guaranteed with an AGM battery or lith-
ium-ion battery. For safety reasons, Mercedes-
Benz recommends that you only use batteries
which have been tested and approved for your
vehicle by Mercedes-Benz.
= Carry over detachable parts, such as vent
hoses, elbow Nttings or terminal covers from
the battery being replaced.
= Make sure that the vent hose is always con-
nected to the original opening on the side of
the battery.
Fit any existing or supplied cell caps.
Otherwise, gases or battery acid could
escape.
= Make sure that detachable parts are recon-
nected in the same way. 400
