Exhaust gas aftertreatment
The exhaust gas aftertreatment requires a
reducing agent known as Diesel Exhaust Fluid
(DEF) in order to function correctly. Filling up
the DEF tank is usually part of the service
scope. DEF consumption depends on opera-
tional and driving conditions and it is not nec-
essary to wait until the next scheduled
service to replenish the fluid. Fluid should be
added regularly to the DEF supply reservoir
during vehicle operation or, at the latest, after
receiving the first warning message via the
on-board computer.
To conform to emission regulations, you must
operate the vehicle with DEF and refill the
supply regularly. The engine management
recognizes attempts to operate the vehicle
without DEF, with thinned DEF or with
another reducing agent. After previous warn-
ing messages, the engine management then
prevents a further engine start.
If the DEF level drops below 1.5 US gal
(5.5 l), the first warning message is issued
and a warning tone sounds. After the mes-
sage appears for the first time, and under
normal driving conditions, the remaining DEF
reserve will last for approximately
1000 miles (1600 km) before the next mes-
sage.
After that, the 0.8 US gal (3.0 l)reserve mark
is reached. Once the reserve range has been
reached, you will receive the next warning
message and you will hear a series of warning
tones. After the first message, the DEF
reserve will last for approximately
1,200 miles (1,900 km) until the next mes-
sage is shown. However, you will only be able
to start the engine another 16 times.
You should immediately add 2.0 US gal
(7.6 l) of DEF (Y page 150) or have the DEF
supply reservoir filled at a qualified specialist
workshop.
When the number of remaining engine starts
is 0
0 the engine management prevents the
vehicle being driven at a speed exceeding 5 mph (8 km/h). The
Idle Mode Idle Modemessage
appears in the multifunction display:
If the 00B9 Check Engine indicator lamp lights
up, the exhaust gas aftertreatment is faulty or
an emission-related malfunction has occur-
red (Y page 213). You will then only be able
to drive a maximum 50 mi (80 km) before the
engine management restricts the number of
starts remaining.
If the exhaust gas aftertreatment is faulty,
have it checked and repaired at a qualified
specialist workshop.
Further information on DEF can be found in
the "Refueling" (Y page 149) and "Service
products and capacities" (Y page 324) sec-
tions. Attachments, bodies, equipment and

Useful information
This Operator's Manual describes all models
as well as standard and optional equipment
of your vehicle that were available at the time
of going to print. Country-specific variations
are possible. Note that your vehicle may not
be equipped with all of the described func-
tions. This also applies to systems and func-
tions relevant to safety.

workshops (Y page 26). Occupant safety
Important safety notes
G
WARNING
Modifications to the restraint systems could
result in them not functioning properly any
more. The restraint systems could then no
longer protect vehicle occupants as they are
designed to do and could fail in the event of
an accident or activate unexpectedly, for
example. There is an increased risk of injury.
Never modify parts of the restraint systems.
Do not attempt to modify the wiring as well as
electronic components or their software.
If it is necessary to modify an air bag system
to accommodate a person with disabilities,
contact an authorized Mercedes-Benz center.
USA only: for further information contact our
Customer Assistance Center at
1-800-FOR-MERCedes (1800-367-6372).
In this section you will learn the most impor-
tant facts about the restraint system compo-
nents of the vehicle.
The restraint system consists of:
R Seat belts
R Child restraint systems
R LATCH-type (ISOFIX) child seat securing
system
SRS (Supplemental Restraint System) and
the air bag system offer additional protection
potential. Although the systems are independent, their
protective functions work in conjunction with
one another.
i
For information on infants and children
traveling with you in the vehicle as well as
restraint systems for infants and children,
see the "Children in the vehicle" section
(Y page 50). SRS (Supplemental Restraint System)
Introduction SRS consists of:
R
007E warning lamp
R Air bags
R Air bag control unit with crash sensors
R ETDs for the driver's and co-driver's seat
R Seat belt force limiters
R Seat belt force limiters for the driver's and
co-driver seats
SRS reduces the risk of occupants hitting
parts of the vehicle interior in the event of an
accident. In addition, it can reduce the forces
the occupants are subjected to during an
accident.
SRS warning lamp G
WARNING
If SRS is malfunctioning, child restraint sys-
tem components may be triggered uninten-
tionally or might not be triggered at all in the
event of an accident with a high rate of vehicle
deceleration. There is an increased risk of
injury, possibly even fatal.
Have SRS checked and repaired immediately
at a qualified specialist workshop.
SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. This allows malfunctions to
be detected in good time. 42
Occupant safetySafety

switched on. The lamp goes out when the
engine starts running.
Braking If ABS intervenes when braking, you will feel
a pulsating in the brake pedal.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions and func-
tions as a reminder to take extra care while
driving.
X If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To make a full brake application:
depress the brake pedal with full force. BAS (Brake Assist System)
G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Vehicles without steering wheel buttons: if
the BAS driving safety system is malfunction-
ing, the 003Dwarning lamp lights up while the
engine is running (Y page 221).
BAS operates in emergency braking situa-
tions. If you depress the brake quickly, BAS
automatically increases the brake pressure,
thereby reducing the stopping distance.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. EBD (electronic brake force distribu-
tion)
G
WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This
increases the risk of skidding and an accident. You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
EBD monitors and controls the brake pres-
sure to the rear wheels. This enables EBD to
improve handling during braking.
Observe the information on warning and indi-
cator lamps (Y page 221). ESP
®
(Electronic Stability Program)
Observe the important safety guidelines for
the driving safety system (Y page 56). G
WARNING
If ESP ®
is malfunctioning it will not provide
any vehicle stabilization. There is an increased
risk of skidding or of an accident.
Exercise caution when continuing to drive.
Have ESP ®
checked at a qualified specialist
workshop.
! Only operate the vehicle briefly (maxi-
mum of 10 seconds) on a brake dynamom-
eter. The key must be turned to position 1
in the ignition lock during this time. You
could otherwise damage the drive train or
the brake system.
! Do not run the vehicle on a roller dyna-
mometer (e.g. for performance tests). If
you must operate the vehicle on a roller
dynamometer, please consult a qualified
specialist workshop in advance. You could
otherwise damage the drive train or the
brake system.
If ESP ®
is malfunctioning, the 0089warning
lamp lights up while the engine is running and
the engine power may be reduced
(Y page 221).
Only use wheels with the recommended tire
sizes. Only then will ESP ®
function properly.
If you select the drive program S+on a vehicle
with an AGILITY SELECT switch, ESP ®
only
stabilizes the vehicle to a limited degree. Driving safety systems

Adaptive Brake Assist
i Observe the "Important safety notes" sec-
tion for driving safety systems
(Y page 56). G
WARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist may:
R intervene unnecessarily
R not intervene
There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. Terminate the
intervention in a non-critical driving situation. G
WARNING
Adaptive Brake Assist does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R to stationary obstacles
R when cornering
As a result, Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake.
Adaptive Brake Assist aids you when braking
during hazardous situations at speeds above
20 mph (30 km/h). With the help of the radar
sensor system, adaptive Brake Assist can rec-
ognize obstacles that are in the path of your
vehicle for an extended period of time.
When you approach an obstacle and adaptive
Brake Assist detects that there is a risk of a
collision, adaptive Brake Assist calculates the
braking force necessary to avoid a collision.
Should you apply the brakes forcefully, adap-
tive Brake Assist will automatically increase
the braking force to the calculated level.
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking. Driving safety systems
59Safety Z

The brakes function as usual again if:
R you release the brake pedal
R there is no longer any danger of a collision
R no obstacle is detected in front of your
vehicle
Adaptive Brake Assist is then deactivated.
Up to the maximum vehicle speed, adaptive
Brake Assist can react to moving obstacles
that have already been recognized as such at
least once over the period of observation.
Adaptive Brake Assist does not react to sta-
tionary obstacles.
In particular, the detection of obstacles can
be impaired if:
R dirt on the sensors or anything else cover-
ing the sensors
R it is snowing or raining heavily
R there is interference from other radar sour-
ces
R there are strong radar reflections, for
example in parking garages
R a narrow vehicle is traveling in front, e.g. a
motorbike
R a vehicle is traveling in front on a different
line
If adaptive Brake Assist is not available due
to a malfunction in the radar sensor system,
the full brake boosting effect with the help of
BAS remains available.
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at slow speeds where there is no visible
damage to the front of the vehicle. ASR (acceleration skid control)
General notes Important safety notes
ASR can neither reduce the risk of an accident
nor suspend the laws of physics if the driver
does not pay attention when pulling away or accelerating. ASR is only an aid. Always adapt
your driving style to suit the prevailing road
and weather conditions.
Vehicles without steering wheel buttons: if
ASR is malfunctioning, the
003Dindicator
lamp lights up while the engine is running and
the engine power may be reduced
(Y page 221).
ASR significantly improves traction, i.e. the
transmission of power from the tires to the
road surface, and thus increases the vehicle's
driving stability. If the driving wheels start to
spin, ASR brakes individual drive wheels and
limits the engine torque. ASR thus signifi-
cantly assists you when pulling away and
accelerating, especially on wet or slippery
roads.
If traction on the road surface is not sufficient,
even ASR will not allow you to pull away with-
out difficulty. The type of tires and total
weight of the vehicle as well as the gradient
of the road also play a crucial role.
If ASR intervenes, the 0072warning lamp in
the instrument cluster flashes.
Activating/deactivating ASR G
WARNING
If deactivated, ASR will not attempt to stabi-
lize the vehicle during pulling away and accel-
eration. There is an increased risk of skidding
and of an accident.
Only deactivate ASR in the situations descri-
bed in the following.
! If you deactivate ASR, ESP ®
will still inter-
vene to stabilize the vehicle. Frequent brak-
ing automatically triggered by ESP ®
can
damage the brake system.
For this reason, deactivate ASR only briefly
and when absolutely necessary. 60

DANGER
Xenon bulbs carry a high voltage. You can get
an electric shock if you remove the cover of
the Xenon bulb and touch the electrical con-
tacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the Xenon bulb. Always have work on
the Xenon bulbs carried out at a qualified spe-
cialist workshop. G
WARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
! Make sure the bulbs are always securely
installed.
If your vehicle is equipped with Bi-Xenon
bulbs, you can recognize this by the following:
the cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the low-beam headlamps must be
switched on before starting the engine.
The bulbs and lamps are an essential compo-
nent of vehicle safety. You must therefore make sure that these function correctly at all
times. Have the headlamp setting checked
regularly.
R
Always switch off the vehicle's lighting sys-
tem before changing a bulb.
This will prevent a short circuit.
R Do not touch the glass tube of new bulbs
with your bare hands. Always use a clean,
lint-free cloth or only touch the base of the
bulb when installing.
Even minor contamination can burn into
the glass surface and reduce the service life
of the bulbs.
R Do not use a bulb that has been dropped or
that has scratches on its glass tube.
The bulb could may explode.
R Only use bulbs in closed lamps which have
been designed for this purpose.
R Only use spare bulbs of the same type and
with the prescribed voltage
R Protect the bulbs from moisture when in
use.
If the new bulb still does not light up, consult
a qualified specialist workshop.
R Have the LEDs and bulbs of the following
lamps changed at a qualified specialist
workshop:
-the additional turn signals in the exterior
mirrors
- the high-mounted brake lamp
- LED daytime running lamps
- the Bi-Xenon bulbs
- front fog lamps
If you require assistance changing bulbs, con-
sult a qualified specialist workshop. Lamp failure indicator
The bulb failure indicator is only an aid. You
are responsible for the proper functioning of
the vehicle lighting. Insufficient or non-func-
tioning vehicle lighting puts the operating
