MERCEDES-BENZ C-280 1999 Owners Manual

Drive Sensibly - Save Fuel


Fuel consumption, to a great extent, depends on driving habits and operating conditions. To save fuel you should:
• keep tires at the recommended inflation pressures,
• remove unnecessary loads,
• remove roof rack when not in use,
• allow engine to warm up under low load use,
• avoid frequent acceleration and deceleration,
• have all maintenance work performed at regular intervals by an authorized Mercedes-Benz dealer.

Fuel consumption is also increased by driving in cold weat her, in stop-and-go traffic, on short trips and in hilly country.

Catalytic Converter
Your Mercedes-Benz is equipped with monolithic type catalytic converters, an important element in
conjunction with the oxygen sensors to achieve substantial control of the pollutants in the exhaust
emissions. Keep your vehicl e in proper operating condition by following our recommended
maintenance instructions as outlined in your Service Booklet.


Caution!
To prevent damage to the catalytic converters, use only premium unleaded gasoline in this vehicle.
Any noticeable irregularities in engine operation shou ld be repaired promptly. Otherwise, excessive
unburned fuel may reach the catalytic converter causing it to overheat, which could start a fire.



Warning!
As with any vehicle, do not idle, park or operate this vehicle in areas where combustible
materials such as grass, hay or leaves can come into contact with the hot exhaust system,
as these materials could be ignited and cause a vehicle fire.

Starting and Turning Off the Engine

Before Starting
Ensure that parking brake is engaged and that selector lever is in position "P" or "N".
Turn electronic key in steering lock to position 2. The charge indicator lamp should come on.

Starting (Model C 230)

Do not depress accelerator. Turn electronic key in steering lock clockwise to the stop.
Release electronic key only when the engine is firing regularly.


Starting
(Models C 280, C 43 AMG)
Do not depress accelerator. Briefly turn electronic ke y in steering lock clockwise to the stop and release.
The starter will engage until the engine is running. If engi ne will not run, and the starting procedure stops,
turn electronic key completely to the left and repeat star ting the engine. After several unsuccessful attempts,
have the system checked at the near est authorized Mercedes-Benz dealer.


Important!
Due to the installed starter non- repeat feature, the electronic key must be turned completely to the left before
attempting to start the engine again. The battery charge indicator lamp should go out as soon as the engine
has started. In areas where temperat ures frequently drop below -4°F (-20°C) we recommend that an engine block
heater be installed. Your authorized Mercedes -Benz dealer will advise you on this subject.

Turning Off


Turn the electronic key in the steering lock to position 0 to stop the engine.
The electronic key can only be removed with your foot off the brake pedal and the selector lever in position "P".

Driving Instructions
Warning !
If you feel a sudden significant vibration or ride disturbance, or you suspect that possible damage
to your vehicle has occurred, you should turn on the hazard flashers, carefully slow down, and drive with

caution to an area which is a safe distance from the roadway.
Inspect the tires and under the vehicle for possible dama ge. If the vehicle or tires appear unsafe, have
it towed to the nearest Mercedes-Benz or tire dealer for repairs.


Power Assistance
Warning !
When the engine is not running, the brake and steering systems are without power assistance.
Under these circumstances, a much greater effo rt is necessary to stop or steer the vehicle.



Brakes
Warning !
After driving in heavy rain for some time without applying the brakes or through water deep enough to
wet brake components, the first braking action may be somewhat reduced and increased pedal
pressure may be necessary. Be sure to maintain a safe distance from vehicles in front.

Resting your foot on the brake pedal will cause excessive and premature wear of the brake pads.
It can also result in the brakes overheating th ereby significantly reducing their effectiveness.
It may not be possible to stop the car in sufficient time to avoid an accident.


The condition of the parking brake system is checked eac h time the car is in the shop for the required service.

If the parking brake is released and the brake warning lamp in the instrument cluster stays on, the brake fluid level in
the reservoir is too low. Brake pad wear or a leak in the system may be the reason for low brake fluid in the reservoir.

Have the brake system inspected at an aut horized Mercedes-Benz dealer immediately.
All checks and maintenance work on the brake system s hould be carried out by an authorized Mercedes-Benz dealer.
Install only brake pads and brake fluid recommended by Mercedes-Benz.


Warning !
If other than recommended brake pads are installed, or other than recommended brake fluid is used, the
braking properties of the vehicle can be degraded to an extent that safe braking is substantially impaired.

This could result in an accident.


Caution !
When driving down long and steep grades, relieve the load on the brakes by shifting into a lower gear. This helps prevent
overheating of the brakes and reduces brak e pad wear. After hard braking, it is advisable to drive on for some time, rather
than immediately parking, so the air stream will cool down the brakes faster.

Tires

Tread wear indicators (TWI) are required by law. These
indicators are located in six places on the

tread circumference and become visible at a depth of
approximately1/16 in (1.5 mm), at which point the
tire is considered worn and should be replaced.

The tread wear indicator appears as a solid band across
the tread.





Warning !
Do not allow your tires to wear down too far. As tread depth approaches 1/16 in (1.5 mm), the adhesion
properties on a wet road are sharply reduced. Depending upon the weather and/or road surface (conditions),
the tire traction varies widely.



Specified tire pressures must be maintained. This ap plies particularly if the tires are subjected to
high loads (e.g. high speeds, heavy loads, high ambient temperatures).



Warning !
Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may lose control
of the car. Continued driving with a flat tire or driving at high speed with a flat tire will cause excessive heat
build-up and possibly a fire.



Aquaplaning
Depending on the depth of the water layer on the road, aquaplaning may occur, even at low speeds and with new
tires.
Reduce vehicle speed, avoid track grooves in the road and apply brakes cautiously in the rain.



Tire Traction
The safe speed on a wet, snow covered or icy road is always lower than on a dry road.
You should pay particular attention to the condition of t he road whenever the outside temperatures areclose to the
freezing point.



Warning !
If ice has formed on the road, tire traction will be substantially reduced. Under such weather conditions,
drive, steer and brake with extreme caution.



We recommend M + S radial- ply tires for the winter season for all four wheels to insure normal balanced handling
characteristics. On packed snow, they can reduce y our stopping distance as compared with summer tires.
Stopping distance, however, is still considerably greater than when the road is wet or dry.


Tire Speed Rating
Model C 36 AMG only: This vehicle is factory equipped with "Z "-rated tires. All other models: Your vehicle is factory
equipped with "H"-rated tires, which have a European speed rating of 130 mph (210 km/h). An electronic speed
limiter prevents your vehicle from exc eeding the speed rating. Despite the tire rating, local speed limits should be
obeyed. Use prudent driving speeds appropriate to prevailing conditions.

ProCarManuals.com

Warning !
Ev
en 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 reduc
e 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 your key and lock vehicle when leaving


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


Winter Driving Instructions
The mo
st important rule for slippery or icy roads is to drive 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 pro duce the 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 pr erequisite 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 observing the safety rules in the previous paragraph.



Warning !
If the v
ehicle 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 not drive through flooded areas or water of unknown depth. 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 transmis sion that 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.
