air suspension MERCEDES-BENZ SPRINTER 2015 MY15 Operator’s Manual

R
Adjust the head restraint so that it supports
the back of the head at eye level.
R The distance from the pedals should be
such that you can depress them fully.
Observe also the safety notes in the section
on "Air bags" (Y page 47)and "Children in the
vehicle" (Y page 51).
If you swap over the head restraints for the
front and rear seats, you will not be able to
adjust the height and angle of the head
restraints to the correct position.
Use the head restraint pad to adjust the head
restraint so that it is as close as possible to
the back of your head.
Before the journey, make sure the head
restraints have been correctly set for each of the vehicle's passengers (Y page 86).Driver's and co-driver's seat

wheel 0044upwards.
This increases the support provided to the
lumbar region.
X Turn handwheel 0044downwards.
This reduces the support provided to the
lumbar region. Seats

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). Important safety notes
G
Warning
A flat tire severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is a risk of an accident.
do not drive with a flat tire. Immediately
replace the flat tire with your spare wheel, or
consult a qualified specialist workshop. G
WARNING
If wheels and tires of the wrong size are used, the wheel brakes or suspension components
may be damaged. There is a risk of an acci-
dent.
Always replace wheels and tires with those
that fulfill the specifications of the original
part.
When replacing wheels, make sure to use the
correct:
R designation
R model
When replacing tires, make sure to use the
correct:
R designation
R manufacturer
R model
Accessories that are not approved for your
vehicle by Mercedes-Benz or are not being
used correctly can impair operating safety. Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and inquire about:
R suitability
R legal stipulations
R factory recommendations
Contact an authorized Sprinter dealer if you
require information on tested and recommen- ded wheels and tires for summer and winter
driving. Advice on purchasing and caring for
tires is also available there.
Information on tire and wheel dimensions and
types as well as the recommended tire pres-
sure for your vehicle can be found in the "Tire pressure" section (Y page 294).
This data can also be found on the Tire and
Loading Information placard on the B-pillar.
Modifications to the brake system or wheels
are not permitted. The use of wheel spacers
or brake dust shields is not permitted. This
invalidates the general operating permit for
the vehicle.
i Further information on wheels and tires
can be obtained at any qualified specialist
workshop. Operation
Information for a journey
If the vehicle is heavily laden, check the tire
pressures, and correct them, if necessary
(Y page 288).
While driving, pay attention to vibrations,
noises and unusual handling characteristics,
e.g. pulling to one side. This may indicate that
the wheels or tires are damaged. If you sus-
pect that a tire is defective, reduce your
speed immediately. Stop the vehicle as soon
as possible to check the wheels and tires for
damage. Hidden tire damage could also be
causing the unusual handling characteristics. If you find no signs of damage, have the tires
and wheels checked at a qualified specialist
workshop. 284
OperationWheels and tires

Always observe the maximum permissible
speed specified for the M+S tire s you have
mounted.
If you mount M+S tires that have a lower max- imum permissible speed than that of the vehi-cle, affix a corresponding warning label in the
driver's field of vision. You can obtain this at a qualified specialist workshop.
Once you have mounted the winter tires:
X Check the tire pressure (Y page 288).
X Reactivate the tire pressure moni-
tor* (Y page 293). Snow chains
G
WARNING
If you drive too fast with snow chains moun-
ted, they may snap. As a result, you could
injure others and damage the vehicle. There is a risk of an accident.
Observe the maximum permissible speed for
operation with snow chains.
When driving with snow chains installed, do
not exceed the maximum permissible speed
of 30 mph (50 km/h). Observe the country-
specific laws and regulations for operation
with snow chains.
! Check the snow chains for damage before
mounting them. Damaged or worn snow
chains may snap and damage the following
components:
R wheel
R wheel housing
R wheel suspension
For this reason, you must use only snow
chains that are free of defects. Observe the manufacturer's mounting instructions.
! Vehicles with steel wheels:
if you
mount snow chains on steel wheels, you
may damage the hub caps. Remove the hub caps from the relevant wheels before
mounting the snow chains. Snow chains increase traction on roads in
wintry conditions.
For reasons of safety we only recommend
using snow chains or traction aids that are
approved for the Sprinter. The snow chains or
traction aids must be of class U or meet the
SAE type U specificatio n. Information on
snow chains is available at any qualified spe- cialist workshop.
When mounting snow chains, please bear the following points in mind:
R Snow chains cannot be mounted on all
wheel/tire combinations. When mounting
the snow chains, note the permissible tire
and snow chain dimensions.
R Mount snow chains only in pairs and only to
the rear wheels. On vehicles with twin tires, mount the snow chains to the outer wheels.Observe the manufacturer's mounting
instructions.
R Only use snow chains when the road is cov-
ered by a layer of snow. Remove the snow
chains as soon as possible when you come
to a road that is not snow-covered.
R The use of snow chains may be restricted
by local regulations. Observe the appropri-
ate regulations before mounting snow
chains.
R When driving with snow chains installed, do
not exceed the maximum permissible
speed of 30 mph (50 km/h).
R Check the tension of the chains after a dis-
tance of approximately 0.5 miles (1.0 km).
You can deactivate ASR (Y page 58) when
pulling away with snow chains mounted. This allows the wheels to spin in a controlled man- ner, achieving an increased driving force (cut-
ting action). Operation in winter

General notes
If your vehicle is equipped with a spare wheel, the spare wheel is under the rear of the vehi-
cle (Y page 312).
Information about installing a wheel can be
found in the "Wheel change" section
(Y page 306).
When you replace a tire, we recommend that
you also replace the tire valve. Please observe
the safety-relevant information on tire valve
(Y page 290). Changing wheels

WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions. The wheel brakes or suspension components
may also be damaged. There is a risk of acci-
dent. Rotate front and rear wheels only if the wheels
and tires are of the same dimensions.
! On vehicles equipped with a tire pressure
monitor, electronic components are loca-
ted in the wheel.
Tire-mounting tools should not be used
near the valve. This could damage the elec- tronic components.
Only have tires changed at a qualified spe-cialist workshop.
Always observe the instructions and safety
notes in the "Mounting a wheel" section
(Y page 306).
The wear patterns on the front and rear tires
differ, depending on the operating conditions. Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires in the center.
If your vehicle's tire configuration allows, you can rotate the wheels according to the inter-
vals in the tire manufacturer's warranty book
in your vehicle documents. If no warranty
book is available, the tires should be rotated
every 3,000 to 6,000 miles (5,000 to
10,000 km), or earlier if tire wear requires. Do
not change the direction of rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is rotated.
Check the tire pressure and reactivate the tire pressure monitor if necessary. Diagram showing tire rotation for single and dual
