section, as that could result in serious
injuries in the event of an accident.
R All occupants should wear their seat belt at
all times, because seat belts help reduce
the likelihood of and potential severity of
injuries in accidents, even if the vehicle
rolls over. The integrated restraint system
is equipped with SRS (driver's air bag, front-
passenger air bag, thorax side impact air
bags, window curtain air bags for side
windows), Emergency Tensioning Devices
and seat belt force limiters.
The system is designed to enhance the
protection offered to occupants who are
properly secured during certain frontal
impacts (front air bags and Emergency
Tensioning Devices) and side impacts
(thorax side impact air bags, window
curtain air bags and Emergency Tensioning
Device) that exceed preset deployment
thresholds, as well as in certain situations
where the vehicle rolls over (window
curtain air bags and Emergency Tensioning
Device).
R Never route the shoulders ection of the
seat belt under your arm, across your neck
or anywhere other than across your
shoulder. In the event of a frontal impact,
your body would be moved too far forward.
This would increase the risk of head and
neck injuries. The seat belt would then
apply excessive force to the ribs or
abdomen, which could cause severe
internal injuries to organs such as the liver
or spleen.
Adjust the seat belt so that the upper part
of the belt is as close as possible to the
center of the shoulder. It should not touch
the neck. Never route the belt under the
shoulder. The height of the belt outlet can
be altered to ensure correct usage.
R The lap belt should be routed as low as
possible across the hips, not across the
abdomen. If the lap belt is routed across the
abdomen, it could cause serious injuries in
the event of an impact. R
Never route the seat belt over rigid or
fragile objects in or on your clothing, such
as eyeglasses, pens, keys etc., as this could
cause injuries.
R Always ensure that the seat belt is routed
correctly. This is particularly important if
you are wearing loose clothing.
R Never use a seat belt for more than one
person at a time. Never route a seat belt
around more than one person or additional
objects.
R Never wear seat belts if they are twisted.
Otherwise, in the event of an impact, the
full width of the seat belt is unavailable to
distribute the force of the impact. The
twisted seat belt routed across your body
could cause injuries.
R Pregnan twomen should also always use a
three-point seat belt. The lap belt must
always pass across your lap as low down as
possible, i.e. across your hips; not across
your abdomen.
R The backrest should be set as close to
vertical as possible.
R Check the seat belt during the journey in
order to make sure that it is correctly
positioned.
R Never place your feet on the instrument
panel or on the seat. Always keep both feet
on the floor in front of the seat.
R When using a seat belt to secure an infant
restraint system, child restraint system or
a child on a booster seat, always follow the
child restraint system manufacturer's
instructions.

WARNING
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus,
we strongly recommend that children be
placed in the rear seat whenever possible.
Regardless of seating position, children 12
years old and under must be seated and 48

If your vehicle is equipped with a Sprinter
trailer tow hitch, you need a ball coupling that
is approved for the trailer tow hitch.
When mounting and removin gthe approved
ball coupling, observe the relevant
information in the operating instructions of
the ball coupling manufacturer.
If you cannot mount the ball coupling
correctly, remove it. In this case, the ball
coupling may not be used for towing a trailer.
Notes on the permissible dimensions and
weights can also be found on the
identification plate of the trailer tow hitch.
You can obtain advice from a qualified
specialist workshop. Coupling up a trailer
! Do not connect the trailer's brake system
(if featured) to the hydraulic brake system
of the towing vehicle, as the latter is
equipped with an anti-lock brake system.
Doing so will result in a loss of function of
the brake systems of both the vehicle and
the trailer. Trailer coupled ready for use

Most federal states and all Canadian
provinces require by law:
R safety chains between the towing vehicle
and the trailer. The chains should be cross-
wound under the trailer drawbar. They must
be fastened to the vehicle's trailer
coupling, not to the bumper or the axle.
Leave enough slack in the chains. This
allows you to drive round tight corners.
R a separate brake system for certain types
of trailer.
R a safety switch for braked trailers. Find out
the specific requirements according to the
applicable laws.
If the trailer detaches from the towing
vehicle, the safety switch applies the

171Driving an d parking Z
When parking your vehicle, make sure that
the tires do not get deformed by the curb or
other obstacles. If it is necessary to drive over
curbs, speed humps or similar elevations, try
to do so slowly and not at a sharp angle.
Otherwise, the tires, particularly the
sidewalls, can get damaged. Regular wheel and tirec

WARNING
Damaged tires can cause tire inflation
pressure loss .As a result, you could lose
control of your vehicle. There is a risk of
accident.
Check the tires regularly for signs of damage
and replace any damaged tires immediately.
Check the wheels and tires of your vehicle for
damage regularly, i.e. at least every two
weeks, as well as after driving off-road or on
rough roads. Damaged wheels can cause a
loss of tire pressure. Pay particular attention
to damage such as:
R cuts in the tires
R punctures
R tears in the tires
R bulges on tires
R deformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tread across the whole width
of the tire (Y page 275). If necessary, turn
the front wheels to full lock in order to inspect
the inner side of the tire surface.
All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
install anything onto the valve other than the
standard valve cap or other valve caps
approved for your vehicle by dealers listed on
the inside of the front cover. Do not install any
other valve caps or systems, e.g. tire pressure
monitor systems.
Regularly check the pressure of all the tires,
particularly prior to long trips. Adjust the tire
pressure if necessary (Y page 278).The service life of tires depends on various
factors, including the following:
R
driving style
R tire pressure
R mileage Tire tread
G
WARNING
Insufficient tire tread will reduce tire traction.
The tire is no longer able to dissipate water.
This means that on wet road surfaces, the risk
of hydroplaning increases, in particular where
speed is not adapted to suit the driving
conditions. There is a risk of accident.
If the tire pressure is too high or too low, tires
may exhibit different levels of wear at
different locations on the tire tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tires.
Minimum tire tread depth for:
R Summer tires: 000Cin (3 mm)
R M+S tires: 000Din (4 mm)
For safety reasons, replace the tires before
the legally prescribed limit for the minimum
tire tread depth is reached. Bar marking
0005for tread wear is integrated
into the tire tread.
Tread wear indicators (TWIs) are required by
law. Six indicators are positioned over the tire
tread. They are visible once the tread depth
is approximately 000Bin (1.6 mm). If this is the Operation

maximum load-bearing capacity of a tire.
Do not overload the tires by exceeding the
specified load limit. The maximum
permissible load can be found on the
vehicle's Tire and Loading Information
placard on the B-pillar on the driver's side
(Y page 286).
Example:
The load-bearing index 120 indicates a
maximum load of 3,042 lb (1,380 kg) for the
tire. If two load-bearing capacity indices are
specified (as shown above), the first number
states the load-bearing capacity for single
tires, the second number the load-bearing
capacity for twin tires. For further information
on the maximum tire load in kilograms and
pounds, see (Y page 291).290

Tire pressure
Pressure inside the tire applying an outward
force to every square inch of the tire's

bar. Tire pressure should only be corrected
when the tires are cold. Cold tire pressure
The tires are cold:
R if the vehicle has been parked for at least
three hours without direct sunlight on the
tires, and
R if the vehicle has not been driven further
than 1 mile (1.6 km)
Tire tread
The part of the tire that comes into contact
