2000 MERCEDES-BENZ C-Class coolant level

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 weather, in stop-and-go traffic, on short trips and in hilly country.

What You Should Know
at the Gas Station


• Fuel:
To prevent fuel vapors from escaping into open air, fully insert filler nozzle unit. Only fill fuel tank until the filler nozzle
unit cuts out - do not overfill. Leaving the engine running and the fuel cap open can cause the "Check Engine" lamp to
illuminate. Use premium unleaded gasoline: Posted Octane Index 91 (Average of 96 RON/86 MON).
Fuel tank capacity approx. 16.4 US gal (62.0 I).
This includes approx. 2.1 US gal (8.0 I) reserve.

Warning !
Gasoline is highly flammable and poisonous, it burns violently and can cause serious injury. Whenever you are
around gasoline, avoid inhaling fumes and skin contact, extinguish all smoking materials. Never allow sparks, flame
or smoking materials near gasoline!


• Engine Oil:
Engine oil level check, see Index.
Fill quantity between upper and lower dipstick marking level: 2.1 US qt (2.0 I).
Recommended engine oils, see Index.

• Spark Plugs:
Approved spark plugs, refer to "Technical Data".


• Coolant:
For normal replenishing, use water (potable water quality).
For further information (e.g. anticorrosion/antifreeze), refer to Index.

it indicates a malfunction of the fuel
management system or emission control
system, or the fuel cap is not closed tight. In
all cases, we recommend that you have the
malfunction checked as soon as possible.

Low Engine Coolant Level Warning Lamp
With the electronic key in steering lock position 2, the warning lamp comes on.
It should go out when the engine is running. If the warning la mp does not go out after starting the engine, or if it
comes on while driving, then the coolant level has dropped below the required level. If no leaks are noticeable and
the engine temperature does not increase, continue to driv e to the nearest service station and have coolant added to
the coolant system (see Index).
The low engine coolant level warning light should not be ignored. Extended driving with the light illuminated may
cause serious engine damage not covered by the Mercedes-Benz Limited Warranty.
In cases of major or frequent minor coolant loss, have t he cooling system checked at your authorized Mercedes-Benz
dealer as soon as possible.

Note:
Do not drive without coolant in the cooling system. T he engine will overheat causing major engine damage. Monitor
the coolant temperature gauge while driving.

Warning !
Do not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes into contact
with hot engine parts. You can be seriously burned.


Low Windshield and Headlamp Washer System Fluid Level Warning Lamp
With the electronic key in steering lock position 2, the warning lamp comes on. It should go out when the engine is
running. If the warning lamp does not go out after starting the engine, or if it comes on while driving, the level of the
reservoir has dropped to approx.1/4 of the total volume. T he reservoir should be refilled with MB Windshield Washer
Concentrate "S" and water (or commercially available premixed windshield washer solvent/antifreeze, depending on
ambient temperature - see Index) at the next opportunity. The reservoir fo r the windshield and headlamp washer
systems is located in the engine compartment.

Example



Checking Coolant Level
To check the coolant level, the vehicle must be parked on level ground and the engine stopped.
Check coolant level only when coolant is cold.
The coolant level should reach the black top part of the reservoir.


Adding Coolant
If coolant has to be added, a 50/50 mixture of water and MB anticorrosion/antifreeze should be added. The drain
plugs
for the cooling system are located on the right side of the engine block and at the bottom of the radiator.
Anticorrosion/antifreeze, see Coolants in Index.

Warning!
In order to avoid possibly serious burns or injury:
•Use extreme caution when opening the hood if there are any signs of steam or coolant leaking from the
cooling system, or if the coolant temperature gauge indicates that the coolant is overheated.
•Do not remove pressure cap on coolant reservoir if engine temperature is above 194°F (90°C). Allow
engine to cool down before removing cap. The coolant reservoir contains hot fluid and is under pressure.

•Using a rag, slowly open cap approximately 1/2 turn to relieve excess pressure. If opened immediately,
scalding hot fluid and steam will be blown out under pressure.

•Do not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes
into contact with hot engine parts.

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.
