THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 53
2
Engine Oil Consumption
When the engine has passed the break-in period, oil
consumption may reach 0.5 % of the fuel consumption
recorded in actual operating circumstances. In isolated
cases and in arduous operating conditions, oil
consumption may increase to 1 % of the fuel
consumption recorded in actual operating
circumstances.
Engine oil consumption depends on the driving style
adopted and the operating conditions. It can only be
judged after the engine has passed the break-in period.SAFETY TIPS
 Check the vehicle’s lights and the general condition
of the vehicle before each trip.
 Keep tires at the recommended tire inflation
pressure.
 All occupants should fasten their seat belts before
each trip.
 Driving in an environmentally responsible manner
will reduce noise, fuel consumption and exhaust
emissions.
 Allow the engine to warm up under low load use.
 Avoid unnecessarily hard acceleration, driving with
the throttle fully open, and carrying loads not
specifically needed on the journey.
 Stop the engine during lengthy waiting periods, for
example at traffic lights.
 Remove ancillary parts, such as wind deflectors and
roof racks, as soon as they are no longer needed.

180 STARTING AND OPERATING
 Regularly check the tires and rims for damage.
Dented or bent rims can cause tire inflation pressure
loss and damage to the tire beads.
 If vehicle is heavily loaded, check tire inflation
pressure and correct as required.
 Do not allow your tires to wear down too far.
Adhesion properties on wet roads are sharply
reduced at tread depths under 1/8 in (3 mm) for
summer tires and 1/6 in (4 mm) for winter tires.
 When replacing individual tires, you should mount
new tires on the front wheels first.
Tire Care and MaintenanceThe tire inflation pressure should be checked
regularly, i.e. at least each time you refuel the vehicle.
The preferred interval for checking the tire inflation
pressure, however, is before each trip.
For more information on checking tire inflation
pressure, refer to "Recommended Tire Inflation
Pressure".
Tire Inspection
Every time when checking the tire inflation pressure,
the tires should also be inspected for the following:
 excessive treadwear, refer to "Tread Depth"
 cord or fabric showing through the tire’s rubber
 bumps, bulges, cuts, cracks or splits in the tread or
side of the tire
Replace the tire if any of the above conditions is found.
Also inspect the spare tire periodically for condition
and inflation. Spare tires will age and become worn
over time even if never used, and thus should be
inspected and replaced when necessary.
WARNING!
Regularly check the tires for damage. Damaged
tires can cause tire inflation pressure loss. As a re-
sult, you could lose control of your Sprinter vehi-
cle.
Worn, old tires can cause accidents. If the tire
tread is badly worn, or if the tires have sustained
damage, replace them.

186 STARTING AND OPERATING
Recommended Tire Inflation Pressure
The tire inflation pressure (including the spare wheel)
should be checked regularly and adjusted as well asinspecting for signs of tire wear or visible damage. Use
a good quality pocket-type gauge to check tire inflation
pressure.
Do not make a visual judgement when determining
proper inflation. Radial tires may look properly
inflated even when they are underinflated.
The tire inflation pressure should be checked
regularly, i.e. at least each time you refuel the vehicle,
and should only be adjusted on cold tires. The
preferred interval for checking the tire inflation
pressure, however, is before each trip.
The tires can be considered cold if the vehicle has been
parked for at least 3 hours or driven less than 1 mile
(1.6 km) at an ambient temperature of approximately
68 °F (20 °C).
Follow recommended cold tire inflation pressures
listed on Tire and Loading Information placard on the
driver’s door B-pillar.
Keeping the tires properly inflated provides the best
handling, tread life and riding comfort.
The pressure difference between the tires on a single
axle should not exceed 1.5 psi (10 kPa).
WARNING!
Avoid spinning of one drive wheel. This may
cause serious damage to the drivetrain which is
not covered by the Warranty.
WARNING!
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are more
likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort, wear
unevenly, increase stopping distance, and result
in sudden deflation (blowout) because they are
more likely to become punctured or damaged by
road debris, potholes etc.

188 STARTING AND OPERATING
Keep this in mind when checking tire inflation
pressure where the temperature is different from the
outside temperature.
For example:
If inside temperature is 68 °F (20 °C) and the outside
temperature is 32 °F (0 °C) then the cold tire inflation
pressure should be increased by 3 psi (0.2 bar), which
equals 1.5 psi (0.1 bar) for every 18 °F (10 °C) for this
outside temperature condition.
Check tire pressures more often if subject to a wide
range of outdoor temperatures, as tire pressures vary
with temperature changes.Checking Tire Inflation Pressure
The tire inflation pressure should be checked
regularly, i.e. at least each time you refuel the vehicle.
The preferred interval for checking the tire inflation
pressure, however, is before each trip.
Inflation pressures specified on the Tire and Loading
Information placard on the driver’s door B-pillar are
always cold tire inflation pressures. Check and adjust
the tire inflation pressure when the tires are cold. Cold
tire inflation pressure is defined as the tire pressure
after the vehicle has been parked for at least 3 hours or
driven less than 1 mile (1.6 km) at an ambient
temperature of approximately 68 °F (20 °C).
The cold tire inflation pressure must not exceed the
maximum tire inflation pressure molded into the tire
side wall, refer to "Tire Labeling".
If you check the tire inflation pressure when the tires
are warm (the vehicle has been driven for several miles
or sitting less than 3 hours), the reading will be higher
than the cold reading. This is normal. Do not let air out
to match the specified cold tire inflation pressure.
Otherwise, the tire will be underinflated.
WARNING!
Tire pressure may increase during operation.
Never reduce this normal pressure build up or
your tire pressure will be too low.
Underinflated tires wear excessively and/or
unevenly, adversely affect handling and fuel
economy, and are more likely to fail from being
overheated.

Follow the steps below to achieve correct tire inflation
pressure:
 Remove the cap from the valve on one tire. Firmly press a tire gauge onto the valve.
 Read tire inflation pressure on tire gauge and check
against the recommended tire inflation pressure on
the Tire and Loading Information placard on the
driver’s door B-pillar. If necessary, add air to
achieve the recommended tire inflation pressure.
NOTE: If you have overfilled the tire, release tire
inflation pressure by pushing the metal stem of the
valve with e.g. a tip of a pen. Then recheck the tire
inflation pressure with the tire gauge.
 Install the valve cap.
 Repeat this procedure for each tire.
WARNING!
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are more
likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort, wear
unevenly, increase stopping distance, and result
in sudden deflation (blowout) because they are
more likely to become punctured or damaged by
road debris, potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire and
Loading Information placard on the driver’s door
B-pillar. Overloading the tires can overheat them,
possibly causing a blowout.
WARNING!
After inspecting or adjusting the tire inflation
pressure always reinstall the valve cap if
equipped.
This will prevent moisture and dirt from entering
the valve stem, which could damage the valve
stem.

2. Economy
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These
abnormal wear patterns will reduce tread life resulting
in a need for earlier tire replacement. Underinflation
also increases tire rolling resistance and results in
higher fuel consumption.
3. Ride Comfort and Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Overinflation produces a jarring and uncomfortable
ride.Tire Labeling
Besides tire name (sales designation) and
manufacturer name, a number of markings can be
found on a tire.
NOTE: Data shown on tire are for illustration purposes
only. Actual data on tires are specific to each vehicle
and may vary from data shown in the illustration.
(1) DOT, Tire Identification Number (TIN)
(2) Maximum tire load

210 STARTING AND OPERATING
If diesel fuels are used with a sulphur content
exceeding 0.5 % by weight, engine oil change intervals
must be shortened. Please contact your Sprinter Dealer
to obtain the necessary information.
Refueling from drums or canisters may lead to the fuel
becoming contaminated. This in turn can cause faults
in the fuel system. Always filter the fuel before adding
it to the vehicle’s tank.Fuel Filter with Water Separator
Check the water separator when the fuel indicator
lamp does not go out or comes on while the engine
is running.
The interval for changing the fuel filter is reduced to
10,000 miles (about 15,000 km).
WARNING!
Under no circumstances should gasoline be mixed
with diesel fuel.
Due to the high pressure and high temperature in
the injection system, there is a risk of fire and
explosion.
In addition, there is a risk of engine damage.
Always follow basic safety rules when working
with any combustible material.

216 STARTING AND OPERATING
Bleeding the Diesel Fuel System
The diesel fuel system must be bled before starting the
engine.
 Turn the key in the ignition lock position 2 for at
least 30 seconds.
 Return the key to position 0.
 Start the engine three to four times. The engine
control unit indicator lamp± must go out.
NOTE: Too many attempts to start the engine could
drain the battery. If the engine does not start after
several attempts, consult an authorized Sprinter
Dealer.PERMISSIBLE ROOF LOAD
The maximum permissible roof load is:
 Vehicles with low roof 660 lbs (300 kg)
 Vehicles with high roof 330 lbs (150 kg)
 The weight of any load carried on the roof,
including the roof rack, must not exceed the
maximum permissible roof load.
LOADING THE VEHICLE
Two labels on the vehicle show how much weight it
may properly carry.
 The Tire and Loading Information placard can be
found on the driver’s door B-pillar. This placard
tells you important information about the number
of people that can be in the vehicle and the total
weight that can be carried in the vehicle. It also
contains information on the proper size and
recommended tire inflation pressures for the
original equipment tires on the vehicle.
 The Certification Label can be found below the
driver’s seat on an outward facing position of the
mounting pillar. It tells you about the gross weight
