Warning
The operating safety of your vehicle could be jeopardized if maintenance work is carried out
incorrectly. As a
result, you could lose control of the vehicle and cause an accident. In addition,
the safety systems may no longer be able to protect you or others as they are designed to do.
Always have maintenance work carried out at a qualified specialist workshop. The qualified
specialist workshop must have the necessary specialist knowledge and tools to carry out the
work required. We recommend visiting an authorized Sprinter Dealer. In particular, work relevant
to safety or on safety-related systems must be carried out at a qualified specialist workshop. Problem Possible causes/consequences and
0050 SolutionsThe headlamps are

Jump-starting
General notes If the vehicle battery is flat, the engine can be
started from another vehicle using jumper
cables. For this purpose, the vehicle has a
jump-starting connection point in the engine
compartment.
The additional battery in the engine
compartment is
not
suitable for jump-starting
operations. If your vehicle requires jump-
starting, or if you use it to jump-start another
vehicle, use the jump-starting connection
point in the engine compartment. G
Warning
Explosive oxyhydrogen is produced when
batteries are being

charged. When working on
batteries, always make sure that the work
area is well ventilated.
Keep flames and naked lights away from the
battery, and do not smoke.
Prevent the creation of sparks (e.g. when
disconnecting the batteries). Sparks can
ignite the oxyhydrogen gas and cause the
batteries to explode. You and others could be
seriously injured. G
Warning
Due to the gases which escape from batteries,
there is a risk of acid burns when jump-
starting a vehicle.

Do not lean over the battery
while the engine is being jump-started.
! Avoid repeated and lengthy starting
attempts.
Do not use a rapid-charging device to start
the engine. When jump-starting, observe the following
points:
R
jump-starting must only be performed
when the engine and catalytic converter
are cold.
R do not start the engine if the battery is
frozen. Let the battery thaw first.
R when jump-starting, use

only batteries with
the same nominal voltage and a similar
capacity.
R only use jump leads protected against
polarity reversal, with adequate cross-
section and with insulated battery terminal
clamps.
X Make sure that the two vehicles do not
touch.
X Apply the parking brake.
X Move the selector lever of the automatic
transmission to position P.
X Switch off all electrical consumers.
X Switch on the battery isolating switch
(Y page 87).
X Remove the key from the ignition lock.
X Open the hood (Y page 168).

Then, use other positive terminal
clamp 0046 of the jumper cable to turn the
red protective cap of the jump-starting
connection point clockwise and slide it
back and connect positive terminal
clamp 0046 to positive terminal 0086 of the
jump-starting connection point.
i Do not connect the jumper cable to the
additional battery in the engine
compartment. The
additional
battery is not
suitable for jump-starting operations.
X Run the donor vehicle's engine at idling
speed.
X First, connect the negative terminal clamps
of the jumper cable to negative terminal
008A of the donor battery and then to earth
contact 0088 of your own vehicle.
X Start the engine.
i You can

switch electrical consumers
back on but do not switch on the lights.
X First, disconnect the negative terminal
clamps of the jumper cable from earth
contact 0088 and then

from negative terminal
008A of the donor battery.
X First disconnect the positive terminal
clamps of the jumper cable from positive
terminal 0086 of the jump-starting
connection point and then from positive
terminal 0047 of the donor battery.
The red protective cap springs back to its
initial position when positive terminal
clamp 0046 is removed from the jump-
starting connection point. X
Place the cover on positive terminal 0047 of
the donor battery.
i You can now switch the lights on.
X Have the battery checked at a qualified
specialist workshop, e.g. an authorized
Sprinter Dealer. Tow-starting
You cannot tow-start

your vehicle as it has an
automatic transmission. Towing
General notes G
Warning
Tow the vehicle using a rigid towing bar if:
R the engine is not running.
R the voltage supply

or the vehicle's electrical
system is malfunctioning.
There is no power assistance for the steering
and braking when the engine is not running.
You must then use significantly greater force
to steer the vehicle and brake.
Do not tow the vehicle if the key cannot
be turned in the ignition lock. The steering is
then locked and it will not be possible to steer
the vehicle.
When towing another vehicle, its weight
should not be greater than the permissible
gross weight of your vehicle.
Comply with national regulations when
towing.
It is preferable to have the vehicle
transported on a transporter or trailer instead
of towing it. When towing the vehicle, use a
rigid towing bar.
! Only secure the tow cable or tow bar to
the towing eyes. You could otherwise
damage the vehicle.
i Before towing, deactivate the automatic
locking while driving function (Y page 55). 248

Practical advice

down, e.g. with the aid of another person or
by tying the propeller shaft up.
X Always remove the propeller shafts leading
to the driven axles.
! Always use new bolts when installing the
propeller shafts.
With front axle damage
X Turn the key to position 1 in the ignition
lock.
X Raise the front axle. G
Warning
A propeller shaft could fall off as it is being
removed and injure

you. Secure the propeller
shaft before removal to prevent it from falling
down, e.g. with the aid of another person or
by tying the propeller shaft up.
! The ignition must be switched off if the
vehicle is being towed with the front or rear
axle raised. Otherwise, ESP ®
may intervene
and damage the brake system.
With rear axle damage
X Turn the key to position 1 in the ignition
lock.
X Raise the rear axle.
Malfunction in the electrical system
If the battery is defective, the automatic
transmission will be locked in position P. To
shift the automatic transmission to
position N, you must provide power to the
vehicle's electrical system in the same way
as jump-starting ( Y page 247).
Have the vehicle

transported on a transporter
or trailer.
Transporting the vehicle The towing
eye can be used to pull the vehicle
onto a special transporter or trailer for
transportation.
! Only lash the

vehicle down by the wheels
or rims, not by vehicle parts such as axle or steering components. There is otherwise a
risk of damage to the vehicle.
X Move the selector lever of the automatic
transmission to position N.250
