If the “CHECK ENGINE” malfunction  
indicator lamp comes on when the engine is 
running, it indicates a malfunction of the 
fuel management system, emission control 
system, systems which impact emissions, or  
the fuel cap is not closed tight. In all cases,  
we recommend that you have the 
malfunction checked as soon as possible, see 
page 218.  Additional function indicator lamps 
(in the odometer display) 
FSS indicator (Service A), see page 87 
FSS indicator (Service B), see page 87 
The symbols appear in the main odometer display field  
prior to the next suggested service. Depending on  
operating conditions throughout the year, the next  
service is calculated and displayed in days or distance 
remaining. See page 87 for notes on the flexible service 
system (FSS).

Coolant temperature gauge 
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 which is not covered by the 
Mercedes-Benz Limited Warranty.
Wa r n i n g ! 
• 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 vehicle until it cools down.

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.  Tachometer 
The tachometer displays the present engine speed in  
revolutions per minute (RPM). 
To help protect the engine, the fuel supply is interrupted  
if the engine is operated above its specified limit.
Wa r n i n g ! 
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.

through menu for one of the following options: 
1. Date, see page 84. 
2. Compass, see page 84.
3. Stop watch, see page 86. 
4. Present fuel consumption – displays miles per   gallon or liters pe r 100 km. 
5. Average fuel consumption – displays miles per   gallon or liters per 100 km, see page 86. 
6. Distance remaining with fuel presently in tank.  Note: 
The display f lashes when fuel supply drops to the  
reserve level. The distance remaining is no longer

Note:
The presence of buildings, bridges, power lines and  
large antenna masts can influence the displayed  
values. Metallic or magnetic objects in or on the  
vehicle can influence the accuracy of the compass.  To change the compass zones: 
Determine the geographical point of the vehicle with the  
aid of the zone maps below: 
1. Turn key in steering lock to position 2. 
2. Press MODE key repeatedly until the compass   display appears in the trip computer display. 
3. Press RESET key to select the compass zone mode.   The zone selected last is shown in the display.
