2014 MERCEDES-BENZ E400 HYBRID warning light

Automatic deactivation of the hybrid
system
The hybrid system is deactivated
automatically if:
R SRS (Supplemental Restrain tSystem)
activates the restraint system in an
accident
R a short circui tis detected in the hybrid
system.
R one of the hybrid system’s electrical
connections is disconnected.
This ensures that you do not come into
contact with high voltage. High-voltage battery
G
WARNING
The high-voltage battery in the hybrid system
is located on the front bulkhead in the engine
compartment on the right-hand side when
viewed in the direction of travel. If, e. g. in the
event of a vehicle fire, the internal pressure of
the high-voltage battery exceeds a certain
value, flammable gas escapes through a line
in the area of the right front wheel. This
prevents the high-voltage battery from
exploding.
Leave the danger area. If necessary, set up
the warning triangle at asuitable distance.
Observe legal requirements. Driving safety systems
ABS (Anti-lock Braking System)
Braking If ABS intervenes when braking, the yellow
÷ ESP®
indicator lamp flashes in the
instrument cluster (Y page 35). You only
feel the brake pedal pulsating in certain
situations, e.g .onslippery roads.
i Further information about ABS; (see
vehicle Operator's Manual). RBS (Recuperative Brake System)
RBS supports you when braking with an
electronically-controlled brake boost mode
and enables the recovery of kinetic energy. G
WARNING
Always have work on the RBS system, e.g.
replacemen tofbrake pads, carried out at a
qualified specialist workshop.
Certain points must be taken into account
when carrying out work on the RBS system,
e.g. for system restart.
Mercedes-Benz recommends that you use an
authorized Mercedes-Benz Center for this
purpose. In particular, work relevant to safety
or on safety-related systems must be carried
out at a qualified specialist workshop. G
WARNING
If RBS malfunctions, braking resistance may
be reduced and brake pedal travel may be
longer than usual. The brake system is still
fully functional .Ifnecessary, depress the
brake pedal further. Adjust your driving style
and vehicle speed accordingly.
i The first time the brake pedal is
depressed after switching on the engine,
braking resistance may be reduced and
brake pedal travel may be greater than
usual. When you release the brake pedal,
pedal travel then returns to normal.
Remember the following points about RBS
(Y page 20).
The yellow éRBS warning lamp and/or
the red $brake warning lamp light up in
the instrument cluster if RBS is
malfunctioning. Follow the instructions in the
multifunction display (Y page 31).

READY indicator :lights up in the
multifunction display .The vehicle is ready
to drive.
X Depress the brake pedal and select a gear.
i The first time the brake pedal is
depressed, braking resistance is reduced
and brake pedal travel is greater than usual.
Noiseless start
When you start the vehicle, electric operation
mode can be used. The engine starts up when
the power required by the driver exceeds the
power currently available from the electric
motor.
Noiseless start is dependent on the outside
temperature and the operating temperature
of the hybrid system.
If the hybrid system has been started using
noiseless start, green READY indicator :
lights up in the multifunction display.
Pulling away If you are depressing the brake pedal when
shifting the transmission from
Pto Dor Rand
still see the Apply Brake to Shift from 'P' display message in the multifunction
display:
X Depress the brake pedal more firmly and
select the desired transmission position.

G
WARNING
When the vehicle is stationary and the green
READY indicator in the instrument cluster is
lit, this means that the engine has been
switched off automatically. All of the vehicle's
systems remain active.
If you remove your foot from the brake pedal
while in transmission position DorR, the
vehicle may pull away automatically.
There is a risk of an accident.
Exit the vehicle only if:
R both the green and yellow READY
indicators in the instrument cluster are off
R you have secured the vehicle to preven tit
from rolling away.
General notes
The ECO start/stop function automatically
switches off the engine at higher speeds
(Y page 23) and whe nthe vehicle comes to
a stop.
The ECO start/stop function is only available
in drive program E.
The system is operational when READY
indicator :turns green in the multifunction
display.
All vehicle systems remain active, e.g. the
automatic climate control.
Automatic engine switch-off
The engine is switched off automatically,
including when:
R the driver releases the accelerator pedal
and does not exceed a speed of 90 km/h
(140 km/h) (Y page 23) or
R the engine has reached its operating
temperature
R the driver’s seat belt is fastened and the
driver’s door is closed
R the driver only slightly depresses the
accelerator pedal
R the hood is closed and engaged properly 22

WARNING
Vehicles with an electric motor generate
much less driving noise than vehicles with
internal combustion engines. As a result, your
vehicle may not be heard by other road users
in certain situations, for example when
parking or when your vehicle has not been
seen by other road users.
This requires you to adopt aparticularly
anticipatory driving style, as it is necessary to
allow for the possibility that other road users
may behave erratically. G
WARNING
When the vehicle is stationary and the green
READY indicator in the instrument cluster is
lit, this means that th eengine has been
switched off automatically. All of the vehicle's
systems remai nactive.
If you remove your foot from the brake pedal
while in transmission position DorR, the
vehicle may pull away automatically.
There is a risk of an accident. Exit the vehicle only if:
R
both the green and yellow READY
indicators in the instrument cluster are off
R you have secured the vehicle to preven tit
from rolling away.
X Apply the parking brake.
The red $indicator lamp in the
instrument cluster lights up.
X Use the DIRECT SELECT lever to shift the
