2000 MERCEDES-BENZ C-Class ECU

Loading instructions
(Vehicles with enlarged cargo area)

The total load weight including vehicle occupants and luggage/ cargo should not exceed the vehicle capacity
weight indicated on the certification tag which can be found on the left door pillar. The handling characteristics
of a fully loaded vehicle depend greatly on the load distribution. It is therefore recommended to load the vehicle
according to the illustrations shown, with the heaviest items being placed towards the front of the vehicle.
Always place items being carried against front or rear seat backrests, and fasten them as securely as possible.
The heaviest portion of the cargo should always be kept as low as possible since it influences the handling
characteristics of the vehicle.

Notes:
The trunk is the preferred place to carry objects. The enlarged cargo area should only be used for items which
do not fit in the trunk alone.

Warning !
In an accident, during hard braking or sudden maneuvers, loose items will be thrown around inside the
vehicle, and can cause injury to vehicle occupants unless the items are securely fastened in the vehicle.
To help avoid personal injury during a collision or sudden maneuver, exercise care when stowing things.
Put luggage or cargo in the trunk if possible. Do not pile luggage or cargo higher than the seat backs.
Do not place anything on the shelf below the rear window. Never drive vehicle with trunk lid open while
pass-through is not closed and seat backrest sections not locked in its upright position. Deadly carbon
monoxide (CO) gases may enter vehicle interior resulting in unconsciousness and death.

Cargo Tie-Down Rings
(Vehicles with enlarged cargo area)

1. Ring
Carefully secure cargo by applying even load on all four rings
with rope of sufficient strength to hold down the cargo.

Shelf below Rear Window

Warning!
The shelf below the rear window should not be used to carry objects. This will avoid such
objects from being thrown about and injuring vehicle occupants during an accident or
sudden maneuver. The trunk is the preferred place to carry objects.

Night Security Illumination

When exiting the vehicle after driving with the exterior lamps on, they switch on again for added illumination for
approximately 30 seconds after closing the last door. The lamp-on time period can be changed at your
Mercedes-Benz dealer.


Inside Rear View Mirror
Manually adjust the mirror.
Use your inside mirror to determine the size and distan ce of objects seen in the passenger side convex mirror.


Antiglare Night Position
With the electronic key in steering lock position 2, the mirror reflection brightness responds to changes in light
sensitivity. With gear selector lever in position "R", or with the interior lamp switched on, the mirror brightness
does not respond to changes in light sensitivity.

Note:
The automatic antiglare function is restricted, if incoming light is not aimed directly at sensors in the mirror.

Automatic Transmission

The automatic transmission selects individual gears automatically, dependent upon
• Selector lever position
• Program mode selector
• Accelerator position
• Vehicle speed

The gear shifting is process is continuously adapted, dependent on the driving style, the driving situation and the road
characteristics.

Important !
When parking the car or before working on the vehicle with the engine running, firmly depress the parking brake
pedal and shift the selector lever into "P".

Driving
The selector lever is automatically locked while in position "P". To move the selector lever out of position "P", the
service brake pedal must be firmly depressed before the shift lock will release. Shift selector leverto the desired
position only when the engine is idling normally and the service brake is applied. Do not release the brake until
ready to drive. The vehicle may otherwise start creeping when the selector lever is in drive or reverse position.

Warning !
It is dangerous to shift the selector lever out of "P" or "N" if the engine speed is higher than idle speed. If
your foot is not firmly on the brake pedal, the car could accelerate quickly forward or in reverse. You
could lose control of the car and hit someone or something. Only shift into gear when the engine is idling
normally and when your right foot is firmly on the brake pedal.

Important !
After selecting any driving position from "N" or "P", wait a moment to allow the gear to fully engage before
accelerating, especially when the engine is cold.


Accelerator Position
Partial throttle = early upshifting = normal acceleration
Full throttle = later upshifting = rapid acceleration
Kickdown (depressing the accelerator beyond full throttle) = downshifting to a lower gear maximum acceleration.
Once the desired speed is attained, ease up on the accelerator - the transmission shifts up again.





Selector Lever Positions
The automatic gear shifting process can be adapted to specific operating conditions using the selector lever.
P - Parking position.
The parking position is to be used when parking the vehicle. Engage only with the car stopped. The parking
position is not intended to serve as a brake when the vehicle is parked. Rather, the driver should always use
the parking brake in addition to placing the selector lever in park to secure the vehicle.

Note:
The electronic key can be removed from the steering lock only with the foot off the brake pedal and the selector
lever in position "P". With the electronic key removed, the selector lever is locked in position "P".

R - Reverse gear. Shift to reverse gear only with the car stopped.
N - Neutral.
No power is transmitted from the engine to the rear axle. When the brakes are released, the vehicle can be
moved freely (pushed or towed). Do not engage "N" while driving except to coast when the vehicle is in danger of
skidding (e.g. on icy roads, see Winter driving Instructions in Index).

Emission Control
Certain systems of the engine serve to keep the toxic components of the exhaust gases within permissible limits
required by law. These systems, of course, will function properly only when maintained strictly according to factory
specifications. Any adjustments on the engine should, ther efore, be carried out only by qualified Mercedes-Benz
authorized dealer technicians. Engine adjustments should not be altered in any way. Moreover, the specified service
jobs must be carried out regularly according to Mercedes -Benz servicing requirements. For details refer to the
Service Booklet.

Warning !
Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide, and
inhaling it can cause unconsciousness and lead to death.
Do not run the engine in confined areas (such as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are entering the vehicle while driving, have the cause determined and
corrected immediately. If you must drive under these conditions, drive only with at least one window fully
open.


On-Board Diagnostic System
The Sequential Multiport Fuel Injection (SFI) control module monitors emission control components that either provide
input signals to or receive output sign als from the control module. Malfunctions resulting from interruptions or failure
of any of these components are indica ted by the "CHECK ENGINE" malfunction indicator lamp in the instrument
cluster and are simultaneously stored in the SFI control module. If the "CHECK ENGINE" malfunction indicator lamp
comes on, have the system checked at your authorized Mercedes-Benz dealer as soon as possible. With some
exceptions the control module switches off the "CHECK ENGINE" indicator lamp if the condition, causing the lamp to
come on, no longer exists during three consecutive cycles. An on-board diagnostic connector is located in the
passenger compartment near to the parking brake pedal, allowi ng the accurate identification of system malfunctions
through the readout of diagnostic trouble codes.

Headlamp Adjustment

Correct headlamp adjustment is extremely important. Check and readjust headlamps at regular intervals and
when a bulb has been replaced.

Replacing Bulb:
To prevent a possible electrical short circuit, switch off lamp prior to replacing a bulb. When replacing bulbs,
install only 12 volt bulbs with the specified watt rating. When replacing halogen bulbs do not touch glass
portion of bulb with bare hands. Use plain paper or a clean cloth.

Warning !
Halogen lamps contain pressurized gas. A bulb can explode if you:
• touch or move it when hot,
• drop the bulb,
• scratch the bulb.
Wear eye and hand protection.
