AUXILIARY HEATER – WATER OR AIR HEATER
(OPTIONAL)
NOTE: The auxiliary heater (water or air heating
device) can be used whether or not the engine is
running.
After you have filled your vehicle’s gas tank with
winterized diesel fuel for the first time, it is
recommended that you operate the auxiliary heater
before beginning a journey or operating the heater
continuously so that any summer diesel fuel left in the
auxiliary heater can combust.
Before switching the auxiliary heater on make sure that
that the battery is sufficiently charged and that there is
enough fuel in the tank. At least a quarter of the tank
should be filled up. See Fuel Gauge.
WARNING!
The auxiliary heating must not be operated at gas
stations due to the risk of fire and explosion. For
this reason, switch off the auxiliary heating before
refuelling.
Auxiliary heaters emit fumes when in operation,
including carbon monoxide.
Inhaling carbon monoxide is a health hazard and
can result in unconsciousness and death.
For this reason, do not operate auxiliary heating in
enclosed spaces without ventilation or an
extractor system, e.g. in a garage. Otherwise you
could endanger yourself and others.
Always keep the ground under the vehicle as clear
as possible so that the auxiliary heater can receive
enough combustion air and exhaust fumes can
escape. Otherwise you could endanger yourself
and others.
WARNING!
Vehicles for transporting hazardous goods:
Observe the relevant safety regulations.

NOTE: After three successive attempts to start the
heater, a malfunction will be recorded in the integrated
diagnostic system and no further operation on
auxiliary heater will be available (lock-out). The work
to annul the lock-out must be carried out at an
authorized Sprinter Dealer.
The auxiliary heater should be run at least once a
month for about 10 minutes.
The maximum heating period is 120 minutes. For more
information, refer to "Switching the Auxiliary Heater
On and Off - Ignition On".
The auxiliary heater will automatically switch off if the
fuel level is under about 4 US gal (15 l).
In case of faults, refer to "Auxiliary Heater – Tips for
Coping with Problems".
WARNING!
Aerosals, gas cartridges and other pressurized
containers transported in the vehicle may be high-
ly flammable and could explode when heated.
Make sure, particularly on vehicles with an air
heater, that such containers are not placed in the
flow of hot air of the auxiliary heating system
Otherwise there is a risk of severe personal
injuries, death and property damage due to
explosion.
WARNING!
Vehicles with air heater:
For safety reasons, we strongly recommend that
the heat exchanger be replaced by an authorized
Sprinter Dealer after 10 years of use.
If the vehicle is sold, the owner is required to
inform the buyer of this requirement. This should
be done when the Operator’s Manual is
transferred to the buyer.

For more information on tire size designation, load and
speed rating, refer to "Tire Labeling". See an authorized
Sprinter Dealer for information on tested and
recommended rims and tires for summer and winter
operation. They can also offer advice concerning tire
service and purchase.
WARNING!
Using tires other than those approved by the vehi-
cle manufacturer can have detrimental effects,
such as
 poor handling characteristics
 increased noise
 increased fuel consumption
Moreover, tires and rims not approved by the
vehicle manufacturer may, under load, exhibit
dimensional variations and different tire
deformation characteristics that could cause them
to come into contact with the vehicle body or axle
parts. Damage to the tires or the vehicle may be
the result.
WARNING!
Do not use a tire, wheel size or rating other than
that specified for your Sprinter vehicle. Some
combinations of unapproved tires and wheels
may change suspension dimensions and perfor-
mance characteristics, resulting in changes to
steering, handling, and braking of your Sprinter
vehicle. This can cause unpredictable handling
and stress to steering and suspension compo-
nents. You could lose control and have an accident
resulting in serious injury or death. Use only the
tire and wheel sizes with load ratings approved
for your Sprinter vehicle, refer to "Tire and Load-
ing Information". Never use a tire with a smaller
load index or speed index or capacity, other than
what was originally equipped on your Sprinter
vehicle. Using a tire with a smaller load index
could result in tire overloading and failure. You
could lose control and have an accident.
Failure to equip the vehicle with tires having
adequate speed capability can result in sudden
tire failure and loss of vehicle control.

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.

182 STARTING AND OPERATING
Treadwear indicators (TWI) are required by law. These
indicators are located in six places on the tread
circumference and become visible at a tread depth of
approximately 1/16 in (1.6 mm), at which point the tire
is considered worn and should be replaced.
Recommended minimum tire tread depth:
 Summer tires 1/8 in (3 mm)
 Winter tires 1/6 in (4 mm)Storing Tires
Cleaning Tires
Direction of Rotation
An arrow on the sidewall indicates the intended
direction of rotation (spinning) of the tire which
means, the wheel must mounted in the direction of
rotation.
WARNING!
Although the applicable federal motor vehicle
safety laws consider a tire to be worn when the
treadwear indicators (TWI) become visible at ap-
proximately 1/16 in (1.6 mm), do not allow your
tires to wear down to that level. As tread depth ap-
proaches 1/8 in (3 mm) for summer tires or 1/6 in 4
mm) for winter tires, the adhesion properties on a
wet road are sharply reduced.
Depending upon the weather and/or road surface
conditions), the tire traction varies widely.
WARNING!
Keep unmounted tires in a cool, dry place with as
little exposure to light as possible. Protect tires
from contact with oil, grease and diesel fuel.
WARNING!
Never use a round nozzle to power wash tires. The
intense jet of water can result in damage to the
tire.
Always replace a damaged tire.

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.
