for example in case of a vehicle fire,
inflammable gas will escape via a duct. The
inflammable gas escapes to an area
underneath
the vehicles cargo compartment.
This prevents the high-voltage battery from
exploding.
Stay away from this area of the vehicle.
Driving safety systems
ABS (Antilock Brake System)
Braking
When the ABS engages during braking, the
ABS/ESP
®
warning lamp d in the
instrument cluster
(Y page 13) flashes. The
brake pedal will pulsate only in certain
situations, for example on a slippery road.
i
For more information on the ABS, refer to
the Operator's Manual.
RBS (Recuperative Brake System)
The RBS controls braking by blending the
vehicles friction brakes with the hybrid
transmissions recuperative energy function.
The RBS system must perform a self-test
when the ignition is switched on.
X
Make sure the automatic transmission is in
park position P.
X
Switch on the ignition.
X
Apply the brake pedal fully and release it.
The self-test of the RBS is completed.
During the self-test of the RBS, less brake
pedal
pressure than usual is required and the
brake pedal travel is longer. When you release
the brake pedal, the brake pedal travel is as
usual again.
For more information on the RBS, see
(Y page 11).
G
Warning!
If the RBS malfunctions, the yellow RBS
warning lamp é and/or the red brake
warning lamp $ (USA only) or J
(Canada
only) in the instrument cluster comes
on. Read and observe the messages in the
multifunction display that may appear. Find
the subentry “Malfunction” of the entry “RBS
(Recuperative Brake System)” in the index of
this manual and follow the steps described in
that section.
G
Warning!
If the RBS malfunctions, less brake pedal
pressure than usual may be required and the
brake pedal travel may be longer. The brake
system still functions with full effectiveness.
If required, you have to depress the brake
pedal further. Adapt your speed and driving
accordingly.
G
Warning!
Have work on the RBS, e.g. brake pad
replacement, carried out by qualified
technicians only.
When working on the RBS, certain
precautions
must be taken, e.g. when putting
the brake system back into service.
Contact an authorized Mercedes-Benz
Center. Service conducted by qualified
technicians is required particularly for safety-
relevant work and work on safety-relevant
systems such as the RBS.
i
For more information on the braking
system and for driving instructions, refer to
the Operator’s Manual.
BAS (Brake Assist System)
If you apply the brakes very quickly, the RBS
provides full brake boost as fast as possible.
In doing so, less brake pedal pressure than
usual
is required and the brake pedal travel is
longer.
X
Apply continuous full braking pressure until
the emergency braking situation is over.
The ABS will prevent the wheels from
locking.
