2014 MERCEDES-BENZ SPRINTER engine

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.
Read the information on qualified specialist
workshops (Y page 26). Occupant safety

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

restraint system or booster seat recom-
mended for the size and weight of the child.
For additional information, see the "Children
in the vehicle" section.
A child's risk of serious or fatal injuries is sig-
nificantly increased if the child restraints are
not properly secured in the vehicle and/or the
child is not properly secured in the child
restraint.
! Make sure that the seat belt retracts fully.
The seat belt or belt buckle may otherwise
become trapped in the door or the seat
adjustment mechanism. This could dam-
age the door, door trim panels and the seat
belt. Damaged seat belts can no longer ful-
fill their protective function and must be
replaced at a qualified specialist workshop. X

All seat belts in the vehicle, except the driv-
er's seat belt, are equipped with a special seat
belt retractor. This helps to secure the child
restraint system properly in the vehicle. For
further information on "Special seat belt
retractors", see (Y page 54).
Belt warning for drivers and co-drivers Regardless of whether the driver's and co-
driver's seat belts have already been fas-
tened, the
0076seat belt warning lamp lights
up for six seconds each time the engine is
started. It then goes out if the driver and the
co-driver have fastened their seat belts. If the
driver's seat belt is not fastened when the
engine is started, an additional warning tone
will sound. This warning tone switches off
after approximately six seconds or once the
driver's seat belt is fastened. Occupant safety

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.
