2000 MERCEDES-BENZ C-Class ECU

Tire Speed Rating

Model C 43 AMG only: This vehicle is factory equipped with "Z"-rated tires. All other models: These vehicles are factory
equipped with "H"-rated tires, which have a European spee d rating of 130 mph (210 km/h). An electronic speed limiter
prevents your vehicle from exceeding the speed rating. Despit e the tire rating, local speed limits should be obeyed. Use
prudent driving speeds appropriate to prevailing conditions.

Warning !

Even when permitted by law, never operate a vehicle at speeds greater than the maximum speed rating of the
tires. Exceeding the maximum speed for which tires are rated can lead to sudden tire failure causing loss of
vehicle control and resulting in personal injury and possible death.



Parking

Warning !
To reduce the risk of personal injury as a result of vehicle movement, before turning off the engine
and leaving the vehicle always:

1. Keep right foot on brake pedal.
2. Firmly depress parking brake pedal.
3. Move the selector lever to position "P".
4. Slowly release brake pedal.
5. Turn front wheels towards the road curb.
6. Turn the key to steering lock position 0 and remove.
7. Take the electronic key and lock vehicle when leaving.

Important !

It is advisable to set the parking brake whenever parking or leaving the vehicle. In addition, move selector lever
to position "P". When parking on hills, always set the parking brake.



Winter Driving Instructions

The most important rule for slippery or icy roads is to driv e sensibly and to avoid abrupt acceleration, braking and steering
maneuvers. Do not use the cruise control system under such conditions.

When the vehicle is in danger of skidding, move selector le ver to position "N". Try to keep the vehicle under control by
corrective steering action. Road salts and chem icals can adversely affect braking efficiency.

Increased pedal force may become necessary to produce t he normal brake effect. We therefore recommend depressing
the brake pedal periodically when travelling at length on salt-strewn roads. This can bring road salt impaired
braking efficiency back to normal. A prerequisite is, however, that this is done without endangering other drivers on the
road. If the vehicle is parked after being driven on salt treated roads, the braking efficiency should be tested as soon as
possible after driving is resumed while observi ng the safety rules in the previous paragraph.


Warning !
If the vehicle becomes stuck in snow, make sure that snow is kept clear of the exhaust pipe and from
around the vehicle with engine running. Otherwise, deadly carbon monoxide (CO) gases may enter
vehicle interior resulting in unconsciousness and death. To assure sufficient fresh air ventilation, open
a window slightly on the side of the car that is out of the wind.



Deep Water

Caution !
Do riot drive through flooded areas or water of unknown dept h. If you must drive through deep water, drive slowly to
prevent water from entering the engine compartment or being ingested by the air intake, possibly causing damage to
electrical components or wiring, to engine or transmission t hat is not covered by the Mercedes-Benz Limited Warranty.


Passenger Compartment


Warning !
Always fasten items being carried as securely as possible. In an accident, during hard braking or sudden
maneuvers, loose items will be thrown around inside the vehicle, and cause injury to vehicle occupants unless
the items are securely fastened in the vehicle. The trunk is the preferred place to carry objects.

Obtaining Replacement Keys
Your vehicle is equipped with a theft deterrent locking system requiring a special key manufacturing process.
For security reasons, replacement keys can only be obtained from your authorized Mercedes-Benz dealer.

Seats, Front

Warning !
Do not adjust the driver's seat while driving. Adjusting the seat while driving could cause the driver to lose
control of the vehicle. Never ride in a moving vehicle with the seat back reclined. Sitting in an excessively
reclined position can be dangerous.
You could slide under the seat belt in a collision. If you slide under it, the belt would apply force at the
abdomen or neck. That could cause serious or even fatal injuries. The seat backrest and seat belt provide
the best restraint when the wearer is in an upright position and the belt is property positioned on the body.
Never place hands under seat or near any moving parts while a seat is being adjusted

1 - Seat, up/down
2 - Seat, fore7aft
3 - Seat cushion tilt
4 - Backrest tilt
5 - Head restraint

Adjust head restraint to support the back of the head approximately at ear level.
The head restraint angle can also be adjusted manually.
Note:
Your car is equipped with power head restraints, do not try to raise or lower them manually.


Power Seat (Optional on model C230 Kompressor passenger side)
The slide switches are located in each front door. Turn electronic key in steering lock to position 1 or 2 (with a front
door open, the power seats can also be operated with the electronic key removed or in steering lock position 0).

Warning !
When leaving the vehicle always remove the electronic key from the steering lock. The power seats can also
be operated with the driver's or passenger door open. Do not leave children unattended in the vehicle or with
access to an unlocked vehicle. Unsupervised use of vehicle equipment may cause serious personal injury.

Caution !
Do not remove head restraints except when mounting seat covers. For removal refer to Head Restraints, Front, see
Index. Whenever restraints have been removed be sure to reinstall them
before driving.

Important !
Prior to operating the vehicle, the driver should adjust the seat height for proper vision as well as fore/aft placement
and seat back angle to insure adequate control, reach, operation, and comfort. The head restraint should also be
adjusted for proper height. See also airbag section for proper seat positioning. In addition, also adjust the steering
wheel to ensure
adequate control, reach, operation, and comfort, if vehicle so equipped. Both the inside and outside rear view mirrors
should be adjusted for adequate rearward vision. Fasten seat belts. Infants and small children should be seated in a
properly secured restraint system that complies with U.S. Federal Motor Vehicle Safety Standard 213 and Canadian
Motor Vehicle Safety Standard 213. All seat, head restraint, steering wheel, and rear view mirror adjustments as well
as fastening of seat belts should be done before the vehicle is put into motion.

Warning !
Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized
BabySmart™ compatible child seat, which operates with the BabySmart™ system installed in the vehicle to
deactivate the passenger side airbag when it is properly installed. Otherwise they will be struck by the airbag
when it inflates in a crash. If this happens, serious or fatal injury will result. The back seat is the safest place
for children. Infants and small children must ride in the back seats and be seated in an appropriate infant or
child restraint system, which is properly secured with the vehicle's seat belt, fully in accordance with the seat
manufacturer's instructions. A child's risk of serious or fatal injuries is significantly increased if the child
restraints are not properly secured in the vehicle and the child is not properly secured in the child restraint.

Seat Belts and Supplemental Restraint System (SRS)

Your vehicle is equipped with seat belts for all se ats, emergency tensioning retractors for the front
seats, as well as front and side impact airbag s and knee bolsters for driver and front passenger.

Seat Belts

Important !
Laws in most states and all Canadian provinces require seat belt use. All states and provinces
require use of child restraints that comply with U.S. Federal Motor Vehicle Safety Standard 213 and
Canadian Motor Vehicle Safety Standard 213

All child restraint systems are designed to be secure d in vehicle seats by lap belts or the lap belt
portion of a lap-shoulder belt.

For your safety and that of your pass engers we strongly recommend their use.

Warning !
Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz
authorized BabySmart™ compatible child seat, which operates with the BabySmart™ system
installed in the vehicle to deactivate the passenger side front airbag when it is properly
installed. Otherwise they will be struck by the airbag when it inflates in a crash. If this
happens, serious or fatal injury will result. The back seat is the safest place for children.
Infants and small children must ride in back seats and be seated in an appropriate infant or
child restraint system, which is properly secured with the vehicle's seat belt, fully in
accordance with the seat manufacturer's instructions. A child's risk of serious or fatal
injuries is significantly increased if the child restraints are not properly secured in the vehicle
and the child is not properly secured in the child restraint.

Warning !
Never ride in a moving vehicle with the seat back reclined. Sitting in an excessively reclined
position can be dangerous. You could slide under the seat belt in a collision. If you slide
under it, the belt would apply force at the abdomen or neck. That could cause serious or even
fatal injuries. The seat back and seat belts provide the best restraint when the wearer is in an
upright position and belts are properly positioned on the body.


Seat Belt Warning System
With the electronic key in steering lock position 2, a warning sounds for a short time if the driver's
seat belt is not fastened.

Warning !
Failure to wear and properly fasten and position your seat belt greatly increases your risk of
injuries and their likely severity in an accident. You and your passengers should always wear
seat belts.
If you are ever in an accident, your injuries can be considerably more severe without your
seat belt properly buckled. Without your seat belt buckled, you are much more likely
to hit the interior of the vehicle or be ejected from it. You can be seriously injured or killed.
In the same crash, the possibility for injury or death is lessened with your seat belt
buckled.

Warning !

USE SEAT BELTS PROPERLY.
• Each occupant should wear their seat belt at all times, because seat belts help reduce the
likelihood of and potential severity of injuries in accidents, including rollovers. "SRS" (driver
airbag, front passenger airbag, front door side impact airbags), "ETR" (seat belt emergency
tensioning retractors), and knee bolsters are impacts which exceed preset deployment thresholds.
• Improperly positioned seat belts do not provide maximum protection and may
cause serious injuries in case of an accident.
• Never wear the shoulder belt under your arm, against your neck or off your shoulder. In a
crash, your body would move too far forward. That would increase the chance of head and
neck injuries. The belt would also apply too much force to the ribs or abdomen, which could
severely injure infernal organs such as your liver or spleen.

• Position the lap belt as low as possible on your hips and not across the abdomen. If the
belt is positioned across your abdomen, it could cause serious injuries in a crash.
• Each seat belt should never be used for more than one person at a time. Do not fasten a
seat belt around a person and objects.
• Belts should not be worn twisted. In a crash, you wouldn't have the full width of the belt to
manage impact forces. The twisted belt against your body could cause injuries.
• Pregnant women should also use a lap-shoulder belt. The lap belt portion should be positioned
as low as possible on the hips to avoid any possible pressure on the abdomen.

Warning !

USE CHILD RESTRA INTS PROPERLY.
Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz
authorized Baby Smart™ compatible child seat, which operates with the BabySmart™ system
installed in the vehicle to deactivate the passenger side front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it inflates in a crash. If this happens, serious or
fatal injury will result.
According to accident statistics, children are safer when properly restrained in the rear seating
positions than in the front seating positions. Infants and small children must ride in back seats
and be seated in an appropriate infant or child restraint system, which is properly secured with
the vehicle's seat belt, fully in accordance with the seat manufacturer's instructions.
A child's risk of serious or fatal injuries is signi ficantly increased if the child restraints are not
properly secured in the vehicle and the child is not properly secured in the child restraint.
Children too big for child restraint systems must ride in back seats using regular seat belts.
Position shoulder belt across chest and shoulder, not face or neck. A booster seat may be
necessary to achieve proper belt positioning.

Emergency Tensioning Retractor (ETR)

The seat belts for the front seats are equipped with emergency tensioning retractors.
These tensioning retractors are located in each belt's inertia reel and become operationally ready
with the electronic key in steering lock position 1 or 2. The emergency tensioning retractors are
designed to activate only when the seat belts are fastened during frontal impacts exceeding the first
threshold of the SRS and in rear impacts exceeding a preset security level. They remove slack from
the belts in such a way that the seat belts fit more snugly against the body restricting its forward
movement as much as possible. In cases of other frontal impacts, angled impacts, roll-overs, certain
side impacts, or other accidents without sufficient frontal or rear impact forces, the emergency
tensioning retractors will not be ac tivated. The driver and passengers will then be protected by the
fastened seat belts and inertia reel in the usual manner. For seat belt and emergency tensioning
retractor safety guidelines see Safety Guidelines in Index.

Infant and Child Restraint Systems
We recommend that all infants and children be properly restrained at all times while the vehicle is in
motion. All lap-shoulder belts except driver seat have special seat belt retractors for secure fastening
of child restraints. To fasten a child restraint, use th is seat belt: Follow child restraint instructions for
routing. Then pull shoulder belt out completely and let it retract. During the seat belt retraction a
ratcheting sound can be heard to indicate that the spec ial seat belt retractor is activated. The belt is
now locked. Push down on child restraint to take up any slack. To deactivate, release seat belt
buckle and let seat belt retract completely. The seat belt can again be used in the usual manner.

Warning !
Never release the seat belt buckle while vehicle is in motion, since the special seat belt
retractor will be deactivated.

Important !
The use of infant or child restraints is required by law in all 50 states and all Canadian provinces.
Infants and small children should be seated in an approp riate infant or child restraint system properly
secured by a lap-shoulder belt, and that complies with U.S. Federal Motor Vehicle Safety Standard
213 and Canadian Motor Vehicle Safety Standard 213. A statement by the child restraint
manufacturer of compliance with this standard ca n be found on the instruction label on the restraint
and in the instruction manual provided with the re straint. When using any infant or child restraint
system, be sure to carefully read and follow all manu facturer's instructions for installation and use.
Please read and observe warning labels affixed to inside of vehicle.


Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz
authorized BabySmart™ compatible child seat, which operates with the BabySmart™ system
installed in the vehicle to deactivate the passenger side front airbag when it is properly
installed. Otherwise they will be struck by the airbag when it inflates in a crash. If this
happens, serious or fatal injury will result.
According to accident statistics, children are safer when properly restrained in the rear
seating positions than in the front seating positions. Infants and small children must ride in
back seats and be seated in an infant or child restraint system, which is properly secured
with the vehicle's seat belt, fully in accordan ce with the seat manufacturer's instructions.
Infants and small children should never share a seat belt with another occupant. During an
accident, they could be crushed between the occupant and seat belt. Children too big for
child restraint systems must ride in back seats using regular seat belts. Position shoulder
belt across chest and shoulder, not face or neck. A booster seat is necessary to achieve
proper belt positioning for children from 41 Ibs. to the point where a lap/shoulder belt fits
properly without one.
When the child restraint is not in use, remove it from the car or secure it with the seat belt to
prevent the child restraint from becoming a projectile in the event of an accident.

U.S.A. Models only:
Since 1986 all U.S. child restraints comply with U. S. regulations without the use of a tether strap.
Canada Models only: This vehicle is provided with tether anchorages for a top tether strap. Consult
your authorized Mercedes-Benz dealer for installa tion of these anchorages. In compliance with
