\3 Changing the batteriesIf the remote control batteries (remote
keyless entry) are discharged, you will only
be able to lock and unlock the vehicle man-
ually using the key.
If the batteries in the auxiliary heating re-
mote control are discharged, you will only
be able to switch the auxiliary heating on
or off using the auxiliary heating / heater
booster switch inside the vehicle
(\2page 140).
It is advisable to have the batteries
changed at an authorized Sprinter Dealer.You need two CR 2025 3 V cell batteries or
equivalent.
Do not touch the battery contact surfaces.Warning
G
Keep batteries away from children.
Consult a doctor immediately if a battery is
swallowed.
Dispose of used batteries in an environmen-
tally responsible manner.
Danger of explosion if the battery is not cor-
rectly replaced.
Replacements should always be either of
the same type or one which has been rec-
ommended by the manufacturer.
Environmental note
H
Batteries contain materials that can harm
the environment if disposed of improperly.
Recycling of batteries is the preferred meth-
od of disposal. Many states require sellers
of batteries to accept old batteries for recy-
cling.iAlways replace all the batteries at the
same time. Suitable batteries are avail-
able from an authorized Sprinter Deal-
er. You can also have the batteries
changed there and return used batter-
ies.
Remote control
(remote keyless entry)iWhen inserting the batteries, make
sure that they are clean and lint-free.!
CAUTION
Do not operate the remote control
while the battery is being replaced.

Fuel requirements
Only use premium unleaded fuel:
\4The octane number (posted at the
pump) must be 91 min. It is an average
of both the Research (R) octane num-
ber and the Motor (M) octane number:
(R+M) / 2). This is also known as the
ANTI-KNOCK INDEX.
Unleaded gasoline containing oxygenates
such as ethanol, IPA, IBA and TBA can be
used provided the ratio of any one of these
oxygenates to gasoline does not
exceed 10%; MTBE not to exceed 15%.
The ratio of methanol to gasoline must not
exceed 3% plus additional cosolvents.
Using mixtures of ethanol and methanol is
not allowed. Gasohol, which contains 10%
ethanol and 90% unleaded gasoline, can be
used.
These blends must also meet all other fuel
requirements, such as resistance to spark
knock, boiling range, vapor pressure, etc.Fuels for diesel engines Fuel requirements
Only use commercially available vehicular
ULTRA-LOW SULFUR HIGHWAY DIESEL
FUEL (15 ppm SULFUR MAXIMUM).
DaimlerChrysler USA now approves the
use of B5 bio diesel (standard diesel with a
maximum of up to 5% Bio diesel content)
in the Sprinter CRD diesel engine.
Information on diesel quality can normally
be found on the fuel pump.
!
CAUTION
The following may lead to increased
wear or engine damage:
\4Using gasoline that does not meet
the specifications mentioned above
\4The use of non-approved special
additives
!
CAUTION
Marine diesel fuel, bio diesel fuel, heat-
ing oil or the like must not be used.
Do not blend diesel fuel with marine
diesel fuel, bio diesel fuel or heating oil.
The use of such non-approved fuels or
blending diesel fuel may result in mal-
function or cause engine damage.
Damage or malfunctions resulting from
poor fuel quality or from blending spe-
cific fuel additives are not covered by
the Sprinter warranty.
!
CAUTION
As bio diesel can be refined from a vari-
ety of raw materials resulting in widely
varying properties, the only approved
bio diesel content is one that meets
ASTM D6751 specification. It must also
have the necessary oxidation stability
(min. 6h, proved with EN 14112 meth-
od) to prevent damages to the system
from deposits and/or corrosion.
If the B5 Bio diesel blend is not suffi-
ciently labeled to clearly indicate that it
meets the above standards, do not use
it.
