2005 MERCEDES-BENZ E320CDI fuel pressure

430 Practical hintsFlat tire
Screw air hose 4 onto the tire valve.

Insert electrical plug 3 into vehicle ci-
gar lighter socket.

Turn the SmartKey in the ignition to
position1.
or

Press the KEYLESS-GO* start/stop
button on the gear selector lever once
without depressing the brake pedal.

Press I on electric air pump switch 2.
The electric air pump should now
switch on and inflate the tire.

Inflate the tire to approx. 51 psi
(3.5 bar).
This takes about five minutes for the
collapsible tire. Air hose 4 and union
nut5 can become hot duration infla-
tion. Exercise proper caution to avoid
burning yourself when using the equip-
ment.

Press 0 on electric air pump switch 2.

Turn the SmartKey in the ignition to
position0.
or

Press KEYLESS-GO* start/stop button
on the gear selector lever twice without
depressing the brake pedal.
The electric air pump should now be
switched off.

If the tire inflation pressure is above
51 psi (3.5 bar), release excess tire in-
flation pressure using the vent screw.

Detach the electric air pump.

Stow electrical plug 3 and air hose 4
behind flap 1 and place the air pump
back in the trunk.
!Do not operate the air pump longer
than eight minutes without interrup-
tion. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.
Warning!
G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.


453 Technical data
Rims and tires
Rims and tires
Only use tires and rims which have been
specifically developed for your vehicle and
tested and approved by Mercedes-Benz.
Other tires and rims can have detrimental
effects, such as:

Poor handling characteristics


Increased noise


Increased fuel consumption!Moreover, tires and rims not approved
by Mercedes-Benz may, under load, ex-
hibit dimensional variations and differ-
ent tire deformation characteristics
that could cause them to come into
contact with the vehicle body or axle
parts. This may result in damage to the
tires or the vehicle.
iFurther information on tires and rims is
available at any authorized
Mercedes-Benz Center. A placard with
the recommended tire inflation pres-
sures is located on the driver's door
B-pillar. Some vehicles may have sup-
plemental tire pressure information for
driving at high speeds (
page 321) or
for vehicle loads less than the maxi-
mum loaded vehicle condition. If such
information is provided, it can be found
on the placard located on the inside of
the fuel filler flap. The tire pressure
should be checked regularly and
should only be adjusted on cold tires.
Follow tire manufacturer’s mainte-
nance recommendation included with
vehicle.

466 Technical dataFuels, coolants, lubricants etc.Fuel requirements
Gasoline engine
Only use premium unleaded gasoline
meeting ASTM standard D 439.
The octane number (posted at the pump)
must be 91 “min”. It is an average of both
the Research (R) Octane Number 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 must not 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.Diesel engine
Only use commercially available vehicular
diesel fuels No. 2 or No. 1 (ASTM D975
No.2-D or No.1-D).
To prevent malfunctions, diesel fuel with
better cold flow quality is offered in the
winter months. Check with your fuel
retailer.
Coolants
The engine coolant is a mixture of water
and anticorrosion/antifreeze, which pro-
vides:

Corrosion protection


Freeze protection


Boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -22°F (-30°C) and corro-
sion protection.
!Do not fill the tank with gasoline. Do
not mix diesel fuel with gasoline or ker-
osene. The fuel system and engine will
otherwise be damaged, which is not
covered by the Mercedes-Benz Limited
Warranty.
