2017 MERCEDES-BENZ GLE SUV HYBRID warning lights

Hybrid drive system
General notes
Hybrid technology combines a fuel efficient
internal combustion engine with a powerful
electric motor.
Important safety notes
Danger of electric shock
GDANGER
The vehicle's high-voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system
or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Following an accident, do not touch any high-
voltage components and never modify the
vehicle's high-voltage electrical system. Have
the vehicle towed away after an accident and
the vehicle's high-voltage electrical system
checked by a qualified specialist workshop.
When towing a vehicle after an accident, be sure
to observe the following sections in the vehicle
Operator's Manual:
RTransporting the vehicle
RTowing the vehicle with the rear axle raised
RTowing a vehicle with both axles on the
ground
Read the safety instructions on towing and tow-
starting (
Ypage 53).
All components of the hybrid drive system are
marked with yellow warning stickers that warn
you of the danger of high voltage. The cables of
the vehicle's high-voltage electrical system are
orange in color.
The ignition must be switched off when carrying
out general tasks, such as changing bulbs or
checking the coolant level.
Automatic switching off of the hybrid
drive system
If components of the restraint system are acti-
vated during an accident, the hybrid drive sys-
tem is automatically deactivated.
The hybrid drive system is not activated when
the vehicle is started if:
Ran electrical short circuit is detected in the
hybrid drive system
Ran electrical connection in the hybrid drive
system is disconnected
This ensures that you do not come into contact
with high voltage.
Manual switching off of the hybrid drive
system
The hybrid drive system can be deactivated
manually using the high voltage switch-off
device.
!To prevent damage to the hybrid drive sys-
tem please observe the following instruc-
tions:
Ronly deactivate the hybrid drive system
manually in the following situations.
Rwork on the hybrid drive system may only
be carried out at a qualified specialist work-
shop, even when it has been deactivated
manually.
Deactivate the hybrid system manually if:
Rthe 6 restraint system warning lamp in the
instrument cluster lights up after an accident
Rthe vehicle is badly damaged, e.g. after an
accident, and the restraint system compo-
nents were not activated
Rthe vehicle is badly damaged and has to be
towed or transported

Safety

Occupant safety
Restraint system warning lamp
If the restraint system is disrupted, the high-
voltage on-board electrical system may not be
switched off in the event of an accident as inten-
ded.
GDANGER
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This can affect
for example the Emergency Tensioning
Device or the air bag. Furthermore, in the
event of an accident, the vehicle's high-volt-
age electrical system may not be deactivated as intended. You may be electrocuted if you
touch the damaged components of the vehi-
cle's high-voltage electrical system. This
poses an increased risk of injury or even fatal
injury.
Have the restraint system checked and
repaired in a qualified specialist workshop assoon as possible. After an accident, switch off
the ignition immediately and remove the key
from the ignition lock.
A malfunction has occurred if the 6restraint
system warning lamp:
Rdoes not light up after the ignition is switched
on
Rdoes not go out after a few seconds while the
combustion engine or hybrid system is run-
ning
Rlights up again while the combustion engine
or hybrid system is running

Safety

Urban driving
In city traffic, energy is recuperated during fre-
quent deceleration phases.
The vehicle can be driven by the electric motor
alone up to a speed of approximately 80 mph
(130 km/h).
The vehicle is driven by the electric motor alone
only when all conditions for the automatic
engine switch-off are fulfilled.
Further information on the automatic engine
switch-off (
Ypage 23).
Driving on inter-urban roads
The following phases are possible when driving
on inter-urban roads:
Rrapid acceleration (boost mode)
Renergy recuperation
Relectric operation mode
The vehicle can be driven by the electric motor
alone up to a speed of approximately 74 mph
(120 km/ h).
A great deal of recovered energy may be avail-
able, depending on the route profile. This
reduces consumption and emissions.
Highway driving
When driving on a highway, switching off the
combustion engine has a particularly positive
effect on fuel consumption and emissions.
If the driver removes his/her foot from the
accelerator pedal in the Comfortdrive program
and a speed of 80 mph (130 km/h) is not excee-
ded, the combustion engine is automatically
switched off.
Further information on the automatic engine
switch-off (
Ypage 23).
Refueling
Refueling
General information
Observe the important safety notes under
"Refueling" in the vehicle Operator's Manual. Pressure in the fuel tank must be released
before refueling. Otherwise, the fuel filler flap
cannot be opened.
If you unlock/lock the vehicle from the outside,
the fuel filler flap also unlocks/locks.
The position of the fuel filler cap is displayed in
the instrument cluster
8. The arrow next to
the filling pump indicates the side of the vehicle.
Preparing to refuel

or, on vehicles with KEYLESS‑ GO:
XOpen the driver's door.

This is the same as the SmartKey having been
removed.

the malfunction has been rectified the charging
process is resumed automatically.
For information on problems relating to the
charging process, see (
Ypage 35).
Setting the maximum charge current
GWARNING
If the charge current draw via a mains socket
is too high during the charging process, the
external electrical system may overheat.
There is a risk of fire.
Before beginning the charging process, check
the maximum permissible charge current
locally. Consult a qualified expert to do so
where necessary.
If necessary, adjust your vehicle's settings.
!An excessive charge current can blow a fuse
or lead to overheating of the external power
supply. Check whether the external power
supply is compatible with the set charge cur-
rent. If necessary, lower the set charge cur-
rent or use another power socket.
Before starting the charging process at a power
socket, check the maximum permissible charge
current for the relevant power socket or the
building.
You can set the maximum permissible charge
current:
Ron the controls of the charging cable
Rin the Settingsmenu of the on-board com-
puter (Ypage 43)
The lower value of the two charge current set-
tings – on the charge cable controls and in the
on-board computer – determines the maximum
charge current. If you cannot set the precise
maximum permitted charge current, select the
next lowest available value.
Only set the maximum permitted charge current
in the on-board computer menu if:
Rit is not possible to set the charge current on
the charging cable
Rthe precise maximum permitted charge cur-
rent can only be set via the on-board com-
puter
How to set the maximum permissible charge
current on the charging cable, is described as
follows.
XTo adjust the setting: press button?

ted in display =.

Warning and indicator lamps in the instrument cluster
Safety systems
The information "while the engine is running" given in the vehicle Operator's Manual regarding the
signaling behavior of a warning/indicator lamp corresponds to the READY driving status. When a
warning/indicator lamp lights up in the READY driving status with the corresponding information,
the causes/consequences and solutions given in the vehicle Operator's Manual also apply to your
vehicle.
