2017 MERCEDES-BENZ SPRINTER ignition

Method of operation
During the first stage of a collision, the restraint
system control unit evaluates important physi-
cal data relating to vehicle deceleration or accel-
eration, such as:
Rduration
Rdirection
Rintensity
Based on the evaluation of this data, the
restraint system control unit triggers the Emer-
gency Tensioning Devices during a frontal or
rear collision.
An Emergency Tensioning Device can only be
triggered, if:
Rthe ignition is switched on
Rthe components of the restraint system are
operational. You can find further information
under: "Restraint system warning lamp"
(
Ypage 40)
Rthe seat belt buckle tongue has engaged in
the belt buckle of the respective front seat
The Emergency Tensioning Device of the front-
passenger seat is triggered independently of the
lock status of the seat belt.
If the restraint system control unit detects a
more severe accident, further components of
the restraint system are activated independ-
ently of each other in certain frontal collision
situations:
RFront air bags
RWindow curtain air bag on the side on which
the impact occurs
The activation threshold of the Emergency Ten-
sioning Devices and the air bag are determined
by evaluating the rate of vehicle deceleration or
acceleration which occurs at various points in
the vehicle. This process is pre-emptive in
nature. Deployment should take place in good
time at the start of the collision.
The rate of vehicle deceleration or acceleration
and the direction of the force are essentially
determined by:
Rthe distribution of forces during the collision
Rthe collision angle
Rthe deformation characteristics of the vehicle
Rthe characteristics of the object with which
the vehicle has collided
Factors which can only be seen and measured
after a collision has occurred do not play a deci-
sive role in the deployment of an air bag . Nor dothey provide a
n indication of air bag deploy-
ment.
The vehicle can be deformed considerably, with-
out an air bag being deployed. This is the case if
only parts which are relatively easily deformed
are affected and the rate of deceleration is not
high. Conversely, air bags may be deployed even though the vehicle suffers only minor deforma-
tion. This is the case if, for example, very rigid
vehicle parts such as longitudinal body mem-
bers are hit, and sufficient deceleration occurs
as a result.
If the restraint system control unit detects a side
impact, the relevant restraint system compo-
nents are deployed independently of each other.
If the system determines a need for additional
protection for the vehicle occupants, the Emer-
gency Tensioning Devices are triggered.
RSide impact air bag on the side of impact,
independently of the Emergency Tensioning
Device and the use of the seat belt
RWindow curtain air bag on the side of impact,independently of the use of the seat belt and
independently of whether the front-
passenger seat is occupied
iNot all air bags are deployed in an accident.
The different air bag systems work independ-
ently of each other.
How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-
eration and the apparent type of accident:
Rfrontal collision
Rside impact
Children in the vehicle
Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason, we
strongly advise that you install a child restraint
system on a rear seat. Children are generally
better protected there.
If a child younger than twelve years old and
under 5 ft (1.50 m) in height is traveling in the
vehicle:
Ralways secure the child in a child restraint
system suitable for this vehicle. The child

As a result, they could:
Ractivate vehicle equipment and become
trapped, for example
Ractivate 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:
RABS ( Anti-lock Braking System)
RASR (Acceleration SkidControl)
RBAS ( Brake Assist System)
REBD ( Electronic Brake Force Distribution)
RESP®(E lectronic StabilityProgram)
Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of accident nor override the
laws of physics. Driving safety systems are
merely aids designed to assist driving. 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 prevailing road and weather
conditions and maintain a sufficient, safe dis-
tance from other road users. Drive carefully.
Please note that the driving safety systems
described only work optimally when:
Rthere is adequate contact between the tires
and the road surface
Ryou use winter tires (M+S tires), with snow
chains if necessary, when the road conditions
are wintry Pay particular attention to the information
regarding tires, tire tread and winter operation
under "Wheels and tires" (
Ypage 243).
ABS (Anti-lock Braking System)
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 53).
GWARNING
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 !warning
lamp (
Ypage 191).
ABS regulates brake pressure in such a way that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when
braking.
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions. ABS works on slippery surfaces, even when you
only brake gently.
The yellow !warning lamp in the instrument
cluster lights up when the ignition is 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 indication
of hazardous road conditions and functions as a
reminder to take extra care while driving.
XIf ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
XTo make a full brake application: depress
the brake pedal with full force.

or heavy objects on or in front of the seats
next to the emergency exit window.
RThe window handles must not be used as
hooks, e.g. to hang up light objects, bags or
items of clothing.
RWhen exiting the vehicle through the emer-
gency exit window, pay attention to the vehi-
cle height and the local conditions. Particu-
larly children and smaller adults may require
assistance when exiting the vehicle.

vised in the vehicle, particularly children, eld-
erly people or people in need of special assis-
tance. Do not activate the double lock when
people are in the vehicle.
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of park
position Por shift manual transmission into
neutral.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.

Rin metallic objects, e.g. metal cases
This can affect the key's functionality.
Key functions of the remote control
General notes
The vehicle is equipped with either 2 or 4 remote
controls with a folding key, or 4 mechanical
keys. In this Operator's Manual, both the
mechanical keys and the keys with remote con-
trol are referred to as keys. The remote control
key has a range of up to 32 ft (10 m). Use the
remote control of the key only when in immedi-
ate proximity of the vehicle. This prevents theft.
Remote controls that are not included in the
scope of delivery for the vehicle must be pro-
grammed before use. Further information can
be obtained at any authorized Sprinter Dealer.
The key's remote control locks/unlocks the
driver's door and/or the following centrally if
the factory settings have not been changed:
Rthe driver's and the front-passenger door
Rthe sliding doors
Rthe rear doors
iIf the driver's or front-passenger door is not
closed, the corresponding door is not locked.
If a sliding door or a rear door is not closed
properly, none of the rear doors are locked.
If there is a key is in the ignition lock, the remote
control is inoperative. When locking or unlock-
ing the vehicle with the remote control, always
