Outside Temperature Indicator
The temperature sensor is located in the front bumper area. Due to its location, the sensor can be affected by road or
engine heat during idling or slow driving. This means that the accuracy of the displayed temperature can only be
verified by comparison to a thermometer placed next, to the sensor, not by comparison to external displays (e.g. bank
signs etc.).
Adaptation to ambient temperature takes place in steps and depends on the prevailing driving conditions (stop-and-
go or moderate, constant driving) and amount of temperature change.

Warning !
The outside temperature indicator is not designed to serve as an Ice-Warning Device and is therefore
unsuitable for that purpose. Indicated temperatures just above the freezing point do not guarantee that the
road surface is free of ice.


Coolant Temperature Gauge
If the antifreeze mixture is effective to -22°F (-30°C), the boiling point of the c oolant in the pressurized cooling system
of your vehicle is approx. 266°F (130°C). During severe operating conditions and stop-and-go city traffic, the coolant
temperature may rise close to the red marking. The engine should not be operated with the coolant temperature in
the red zone. Doing so may cause serious engine damage wh ich is not covered by the Mercedes-Benz Limited
Warranty.

Warning !
• Driving when your engine is badly overheated can cause some fluids which may
have leaked into the engine compartment to catch fire. You could be seriously burned.
• Steam from an overheated engine can cause serious burns and can occur just by opening
the engine hood. Stay away from the engine if you see or hear steam coming from it.

Turn off the engine, get out of the vehicle and do not stand near the car until it cools down.

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.

Checking Engine Oil Level
Example



1. Oil dipstick
2. Oil filler cap

To check the engine oil level, park vehicle on level ground, with engine at normal operational temperature. Check
engine
oil level approximately 5 minutes after stopping the engine, allowing for the oil to return to the oil pan.


Oil Dipstick:
Wipe oil dipstick clean prior to checking the engine oil level. Fully insert dipstick in tube, and remove after three
seconds to obtain accurate reading.

Oil level must be between the
lower (min) and upper (max)
mark of the dipstick.



Fill quantity between upper and lower dipstick marking level is approximately 2.1 US qt (2.0 I).
Do not overfill the engine.
Excessive oil must be drained or siphoned. It could cause damage to engine and catalytic converter not covered by
the Mercedes-Benz Limited Warranty.
For low engine oil level warning lamp, see Index.
