Ran out MERCEDES-BENZ C-Class 2000 W202 Owner's Guide

Rear Seat Cushion

Removal:
Push in locking tabs (on left and right side of seat) and pull up seat at the front. Installation: Slide rear edge of
cushion under the backrest. Push front of cushion down until it locks in place.

Caution!
Watch out for sharp edges when removing or installing the rear seat cushion, and make sure that it is securely
locked in place again, to prevent personal injury.






Emergency Operation of Sliding/Pop-Up Roof
The sliding/pop-up roof can be opened or closed manually should an electrical malfunction occur.
The sliding/pop-up roof drive is located behind the lens of the left interior lamp between the sun visors.
1. Pry off lens (1) by using a screw driver.
2. Obtain crank (2) (supplied with vehicle) and insert it through hole.

To slide the roof closed or to raise the roof at the rear: turn crank clockwise.
To slide the roof open or to lower the roof at the rear: turn crank counterclockwise.

Layout of Poly-V-belt Drive

The engine is equipped with two poly-V-belts.
For dimensions of the poly-V-belts, see Technical Data in Index.

Premium Unleaded Gasoline

Caution !
To maintain the engine's durability and performance, premium unleaded gasoline must be used. If
premium unleaded is not available and low octane fuel is used, follow these precautions:
• have the fuel tank filled only partially with unleaded regular and fill up with premium unleaded
as soon as possible,
• avoid full throttle driving and abrupt acceleration,
• do not exceed an engine speed of 3000 rpm, if the vehicle is loaded with a light load such as two
persons and no luggage,
• do not exceed 2/3 of maximum accelerator pedal positi on, if the vehicle is fully loaded or operating
in mountainous terrain.


Fuel Requirements
Use only Premium unleaded meeting ASTM standar d 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 k nown as ANTI-KNOCK INDEX. Unleaded gasoline
containing oxygenates such as Ethanol, I PA, IBA and TBA can be used provided the ratio of any
one of these oxygenates to gasoline does not exce ed 10%, MTBE not to exceed 15%. The ratio of
Methanol to gasoline must not exceed 3% plus additional components. Using mixtures of Ethanol
and Methanol is not allowed. Gasohol, which c ontains 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..


Gasoline Additives
A major concern among engine manufacturers is carbon build up caused by gasoline. Mercedes-
Benz recommends the use of only quality gasoline cont aining additives that prevent the build up of
carbon deposits. After an extended period of using fu els without such additives, carbon deposits can
build up especially on the intake valves and in the combustion area, leading to engine performance
problems such as:
• warm-up hesitation,
• unstable idle,
• knocking/pinging,
• misfire,
• power loss.
Do not blend other specific fuel additives with fuel. They only result in unnecessary cost, and may be
harmful to the engine operation. Damage or malfunct ions resulting from poor fuel quality or from
blending specific fuel additives are not covered by the Mercedes-Benz Limited Warranty.

Coolants

The engine coolant is a mixture of water and anticorrosion/antifreeze, which provides:
• 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 approx. -22°F
(-30°C) and corrosion protection. The coolant solution must be used year round to provide the
necessary corrosion protection and increase in the boil-over protection. You should have it replaced
every 3 years. To provide the important corrosion protection, the solution must be at least 45%
anticorrosion/antifreeze (equals a freeze protection to approx. -22°F [-30°C]). If you use a solution
that is more than 55% anticorrosion/antifreeze (freeze protection to approx. -49°F [-45°C]), the engine
temperature will increase due to the lower heat transfer capability of the solution. Therefore, do not
use more than this amount of anticorrosion/antifreeze. If the coolant level is low, water and MB
anticorrosion/antifreeze should be used to bring it up to the proper level (have cooling system
checked for signs of leakage). The water in the cooling system must meet minimum requirements,
which are usually satisfied by normal drinking water. If you are not sure about the water quality,
consult your authorized Mercedes-Benz dealer.

Anticorrosion/antifreeze
Your vehicle contains a number of aluminum parts. The use of aluminum components in motor
vehicle engines necessitates that anticorrosion/antifreeze coolant used in such engines be specifically
formulated to protect the aluminum parts. (Failure to use such anticorrosion/antifreeze coolant will
result in a significantly shortened service life.)
Therefore the following product is strongly recommended for use in your car: Mercedes-Benz
Anticorrosion/Antifreeze Agent. Before the start of the winter season (or once a year in the hot
southern regions), you should have the anticorrosion/antifreeze concentration checked. The coolant is
also regularly checked each time you bring your vehicle to your authorized Mercedes-Benz dealer for
service.

Reporting Safety Defects

If you believe that your vehicle has a defect whic h could cause a crash or could cause injury or
death, you should immediately inform the National Highway Traffic Safety Admi nistration (NHTSA) in
addition to notifying Mercedes-Benz of North Americ a Inc.. If NHTSA receives similar complaints, it
may open an investigation, and if it finds that a safety defect exists in a group of vehicles, it may
order a recall
and remedy campaign. However, NHTSA cannot become involved in individual problems between
you, your dealer, or Mercedes -Benz of North America Inc..
To contact NHTSA, you may either call the Auto Safety Hotline toll-free
at 1-800-424-9393 (or 366-0123 in Washington, D.C. area)
or write to:
NHTSA, U.S. Department of Transp ortation, Washington, D.C. 20590.
You can also obtain other information about motor vehicle safety from the Hotline.
