latest, after receiving the first warning mes-
sage 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 message
appears for the first time, and under normal
driving conditions, the remaining DEF supply
will last for approximately 1000 miles
(1600 km).
If a reserve mark of 0.8 US gal (3.0 l) is
reached, a second warning message is issued and a warning tone sequence sounds. After
the first message, the DEF supply will last for
approximately 1200 miles (1900 km). Subse-
quently, you will only be able to start the
engine a further 16 times.
You should immediately add 2.0 US gal (7.6 l)
of DEF (Y page 147) or have the DEF supply
reservoir filled at a qualified specialist work-
shop.
When the number of remaining engine starts
is 0
0 and the engine is restarted, the engine
management prevents the vehicle from being
driven at a speed exceeding 5 mph (8 km/h).
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 211). 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 147) and "Service
products and capacities" (Y page 320) 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 functions.
This also applies to systems and functions
relevant to safety.
Read the information on qualified specialist
workshops (Y page 25). Occupant safety
Restraint system introduction
The restraint system reduces the risk of vehi- cle occupants coming into contact with parts of the vehicle's interior in the event of an
accident. The restraint system can also
reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system comprises:
R Seat belt system
R Air bags
R Child restraint system
R Child seat securing systems
The components of the restraint system work
in conjunction with each other. They can only
deploy their protective function if, at all times,
all vehicle occupants:
R have fastened their seat belts correctly
(Y page 45)
R have adjusted their seat and head restraint
properly (Y page 82).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the cor-
rect driver's seat position (Y page 82).
You also have to make sure that an air bag can inflate properly if deployed (Y page 47).
An air bag supplements a correctly worn seat
belt. As an additional safety device, the air
bag increases the level of protection for vehi- cle occupants in the event of an accident. For
example, if, in the event of an accident, the
protection offered by the seat belt is suffi-
cient, the air bags are not deployed. When an
accident occurs, only the air bags that
increase protection in that particular accident
situation are deployed. However, seat belts
and air bags generally do not protect against objects penetrating the vehicle from the out-
side.
Information on restraint system operation
can be found under "Deployment of Emer-
gency Tensioning Devices and air bags"
(Y page 49).
For more information about children traveling with you in the vehicle and on child restraint
systems, see "Children in the vehicle"
(Y page 51). Important safety notes
G
WARNING
Modifications to the restraint system, may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in an accident or trigger unexpectedly, for example.
This poses an increased risk of injury or even fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
components or their software.
If it is necessary to modify an airbag system to
accommodate a person with disabilities, con- tact an authorized Sprinter dealership for
details. USA only: contact our Customer
Assistance Center at 1‑877‑762 ‑8267 for
details. Restraint system warning lamp
The restraint systems functions are checked
after the ignition is switched on and at regular
intervals when the engine is running. This 42
Occupant safetySafety

allows malfunctions to be detected in good
time.
When the ignition is switched on, the 0075
restraint system warning lamp in the instru-
ment cluster lights up. It goes out no later
than a few seconds after the vehicle is star-
ted. The components of the restraint system
are on standby.
A malfunction has occurred if the 0075
restraint system warning lamp:
R does not light up after the ignition is
switched on.
R does not switch off after a few seconds.
R goes out, but then lights up again, e.g. when
the engine is running. G
WARNING
If restraint system is malfunctioning, restraint system components may be triggered unin-
tentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emer- gency Tensioning Device or air bag, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible. Seat belts
Introduction Seat belts are the most effective means of
restricting the movement of vehicle occu-
pants in the event of an accident or the vehi-
cle rolling over. This reduces the risk of vehi- cle occupants coming into contact with parts
of the vehicle interior or being ejected from
the vehicle. Furthermore, the seat belt helps
to keep the vehicle occupant in the best posi- tion in relation to the air bag. The seat belt system comprises:
R Seat belts
R Emergency Tensioning Devices and seat
belt force limiters for the driver's and front-
passenger seat belts
On vehicles with two seats on the front-
passenger side, both seat belts on the
front-passenger side have an Emergency
Tensioning Device. Only the seat belt on the
outer front-passenger seat has a seat belt
force limiter.
The seat belt system only includes Emer-
gency Tensioning Devices and seat belt force
limiters for the driver and front passenger if
the vehicle is equipped with a driver's air bag.
If the seat belt is pulled out of the belt outlet quickly or with a jerky movement, the belt
retractor locks. The belt strap cannot be
extracted any further.
The Emergency Tensioning Device tightens
the seat belt in an accident, pulling the belt
close against the body. However it does not
pull the vehicle occupant back in the direction
of the backrest.
The Emergency Tensioning Device does not
correct an incorrect seat position or the rout- ing of an incorrectly fastened seat belt.
When triggered, seat belt force limiters help
to reduce the force exerted by the seat belt on
the vehicle occupant.
The seat belt force limiters are synchronized
with the front air bags, which absorb part of
the deceleration force. This can reduce the
force exerted on the vehicle occupants during an accident.
! If the front-passenger seat is unoccupied,
do not insert the belt tongue into the buckle of the front-passenger seat. This may oth-
erwise lead to the triggering of the Emer-
gency Tensioning Device in the event of anaccident, which will then need to be
replaced.
Vehicles with two seats on the front-
passenger side: the Emergency Tensioning
Device of the inner front-passenger seat is Occupant safety

As a result, they could:
R activate vehicle equipment and become
trapped, for example
R activate or deactivate systems, thereby
endangering other road users
Unsecured animals could also be flung around the vehicle in the event of an accident or sud-
den steering or braking, thereby injuring vehi- cle occupants. There is a risk of an accident
and injury.
Never leave animals unattended in the vehi-
cle. Always secure animals properly during
the journey, e.g. use a suitable animal trans-
port box. Driving safety systems
Overview
In this section, you will find information about the following driving safety systems:
R ABS ( Anti-lock BrakingSystem)
R ASR (A cceleration SkidControl)
R BAS (B rakeAssist System)
R EBD ( Electronic Brake Force Distribution)
R ESP ®
(E lectronic StabilityProgram) Important safety notes
If you fail to adapt your driving style or if you
are inattentive, the driving safety systems can
neither reduce the risk of accident nor over-
ride the laws of physics. Driving safety sys-
tems are merely aids designed to assist driv- ing. You are responsible for the distance to
the vehicle in front, for vehicle speed, braking in good time and for staying in your lane.
Always adapt your driving style to the prevail-
ing road and weather conditions and maintain a sufficient, safe distance from other road
users. Drive carefully.
The driving safety systems described can only
attain their maximum effectiveness when
there is optimum contact between the tires and the road can. Pay particular attention to
the information regarding tires, recommen-
ded minimum tire tread depth etc. under
"Wheels and tires" (Y page 284).
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow
chains. This is the only way to get the full
benefit from the driving safety systems
described. ABS (Anti-lock Braking System)
Important safety notes Observe the important safety guidelines for
the driving safety system (Y
page 57). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid- ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
If ABS is malfunctioning, other systems will
also fail, including driving safety systems.
Observe the information relating to the 0025
warning lamp (Y page 218).
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi-
cle when braking.
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface condi-
tions. ABS works on slippery surfaces, even
when you only brake gently.
The yellow 0025warning lamp in the instru-
ment cluster lights up when the ignition is
switched on. The lamp goes out when the
engine starts running. Driving safety systems
57Safety Z

If you deactivate ASR:
R engine torque is not limited and the drive
wheels are able to spin. The spinning
wheels will then achieve a cutting effect for
better traction.
R traction control remains active through
brake intervention. If a drive wheel attains
its tire traction limit because one side of the
road is slippery, for example, that wheel is
braked. The traction is then increased in
this situation.
R active brake intervention by ESP ®
to
increase driving stability remains active.
The 0072 warning lamp in the instrument
cluster flashes when ESP ®
is intervening. 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 218).
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 is malfunctioning, the rear wheels can
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 218). ESP
®
(Electronic Stability Program)
Important safety notes Observe the important safety guidelines for
the driving safety system (Y
page 57). 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.
! 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 218).
Only use wheels with the recommended tire
sizes. Only then will ESP ®
function properly.
Crosswind Assist Crosswind Assist does not work if ESP
®
is
deactivated or disabled because of a mal-
function. Driving safety systems
