2003 MERCEDES-BENZ C320 4MATIC WAGON lock

333 Technical data
Fuels, coolants, lubricants etc.


Ignition is off during refill.


Immediately after refueling engine is
started and operated for at least five
minutes.
These precautions and recommendations
are supposed to prevent any difficulties
when starting and operating the engine
which otherwise may be experienced be-
fore the engine has fully adapted to the dif-
ferent fuel.
If in spite of these recommendations the
engine does not perform properly, adding
more gasoline (at least 3 gallons
[12 liters]) to the fuel may improve the en-
gine behavior.Cold weather performance
It is possible that starting times will signif-
icantly increase at temperatures below
32°F (0°C). At low temperatures the use
of a block heater (Canada only) is recom-
mended (see your authorized
Mercedes-Benz Center for further informa-
tion). Rough idling may also be experi-
enced at such temperatures before the
engine is fully warmed up.
Hot weather performance
At ambient temperatures above 95°F
(35°C) start times may increase and be ac-
companied by a rough idle following the
start.Cruising range
E85 fuel contains less energy per gallon
than gasoline. To ensure that engine per-
formance with ethanol fuel is similar to
that when using gasoline, the engine must
burn more ethanol fuel. As a result, it is to
be expected that the fuel consumption will
increase when using E85 compared to gas-
oline operation.
Maintenance
Please inform your Mercedes-Benz Center
if you use or have used E85 fuel when your
vehicle is delivered for maintenance or re-
pairs.
!E85 fuel is unsuitable for use when am-
bient temperatures fall below 14°F
(-10°C).
iUse of E85 may reduce your driving
range.

an aid used when changing a tire to align
the wheel with the wheel hub.
BabySmartTM airbag deactivation
system
This system detects if a special system
compatible child restraint seat is installed
on the front passenger seat. The system
will automatically deactivate the passen-
ger front airbag when such a seat is prop-
erly installed (indicator lamp 7 on the
center console lights up). See your autho-
rized Mercedes-Benz Center for availabili-
ty.BabySmartTM compatible child seats
Special restraint system for children. The
sensor system for the passenger seat pre-
vents deployment of the passenger side
airbag if a BabySmartTM compatible child
seat is installed.

distances in emergency braking situa-
tions. The system is activated when it
senses an emergency based on how
fast the brake is applied.

the light source and produce a more in-
tense light than filament headlamps. Bi-xe-
non headlamps produce low beam and
high beam.CAC

ter, which can help you with any ques-
tions about your vehicle and provide
assistance in the event of a break-
down.

(Cockpit Management and Data Sys-
tem)
Information and operating center for
vehicle sound and communications
systems, including the radio and navi-
gation system, as well as for other op-
tional equipment (CD changer*,
telephone*, etc.).
Control system
The control system is used to call up vehi-
cle information and to change component
settings. Information and messages ap-
pear in the multifunction display. The driv-
er uses the buttons on the multifunction
steering wheel to navigate through the sys-
tem and to adjust settings.
Cruise control
Driving convenience system for automati-
cally maintaining the vehicle speed set by
the driver.Engine number
The number set by the manufacturer and
placed on the cylinder block to uniquely
identify each engine produced.
Engine oil viscosity
Measurement for the inner friction (viscos-
ity) of the oil at different temperatures. The
higher the temperature an oil can tolerate
without becoming thin, or the lower the
temperature it can tolerate without be-
coming viscous, the better the viscosity.
ESP
(Electronic Stability Program)
Improves vehicle handling and direc-
tional stability.
ETD
(Emergency Tensioning Device)
Device which deploys in certain frontal
and rear collisions exceeding the sys-
tem's threshold to tighten the seat
belts.
->SRSFSS
(Flexible Service System)
Service indicator in the multifunction
display that informs the driver when
the next vehicle maintenance service is
due.
Gear range
Number of gears which are available to the
automatic transmission for shifting. The

in the driver’s field of vision, including the
tachometer, speedometer, engine temper-
ature display and fuel gauge.

er the door is locked or unlocked. Pushing
the lock button down on an individual door
from inside will lock that door.
Memory function*

commands SELECT RADIO STATION or OP-
ERATE CD PLAYER. Using commands you
can directly change the settings for your
vehicle.
MON
