cluster displayPractical hints Car care Index Automatic central locking
The central locking switch also operates the automatic 
central locking.
With the automatic central locking system activated and 
the engine running, the doors and trunk are locked at 
vehicle speeds of approximately 9 mph (15 km / h) or 
more.
To a c ti va te :
With key in steering lock position 2 hold upper portion 
of switch (1) for a minimum of 5 seconds.
To deactivate:
With key in steering lock position 2 hold lower portion 
of switch (2) for a minimum of 5 seconds.
Notes:
If doors are unlocked with the central locking switch 
after activating the automatic central locking, and 
neither door is opened, then the doors remain unlocked 
even at vehicle speeds of approximately 9 mph 
(15 km / h) or more.If a door is opened from the inside at speeds of 
approximately 9 mph (15 km / h) or less with the 
automatic central locking activated, the door will again 
be automatically locked at speeds of approximately 
9 mph (15 km / h) or more.
Important!
When towing the vehicle, or with the vehicle on a 
dynamometer test stand, please, note the following:
With the engine running, the vehicle doors will lock if 
the left front wheel spins at vehicle speeds of 
approximately 9 mph (15 km / h) or more.
To prevent vehicle door locks from locking, deactivate 
the automatic central locking.
Emergency unlocking in case of accident
The doors unlock automatically a short time after an 
accident in which an airbag or emergency tensioning 
retractor deploys (this is intended to aid rescue and 
exit). However, the key must still be in the steering lock 
position 1 or 2.
Additionally the hazard warning flashers turn on 
automatically and the interior lights switch on for 
approximately 30 minutes.

Te ch n i c a l
data Instruments 
and controlsOperationDrivingInstrument 
cluster displayPractical hints Car care Index Note:
For cleaning and care of the seat belts, see page 302.
Seat belt nonusage warning system
After starting the engine, a warning sounds and the seat 
belt warning lamp< remains illuminated for 
approximately 6 seconds if the driver’s seat belt is not 
fastened.
Wa r n i n g !
Never ride in a moving vehicle with the backrest 
reclined. Sitting in an excessively reclined position 
can be dangerous. You could slide under the seat 
belt in a collision. If you slide under it, the belt 
would apply force at the abdomen or neck. That 
could cause serious or even fatal injuries. The 
backrest and seat belt provide the best restraint 
when the wearer is in an upright position and the 
belt is properly positioned on the body.
Wa r n i n g !
Failure to wear and properly fasten and position 
your seat belt greatly increases your risk of 
injuries and their likely severity in an accident. 
You and your passengers should always wear seat 
belts.If you are ever in an accident, your injuries can be 
considerably more severe without your seat belt 
properly buckled. Without your seat belt buckled, 
you are much more likely to hit the interior of the 
vehicle or be ejected from it. You can be seriously 
injured or killed.In the same crash, the possibility for injury or 
death is lessened if you are wearing your seat belt.Wa r n i n g !
Never let more people ride in the vehicle than there 
are seat belts available. Be sure everyone riding in 
the vehicle is correctly restrained with a separate 
seat belt.

Important!
With the key in steering lock position 2, the indicator 
lamp in the instrument cluster comes on. It should go 
out when the engine is running.
If the indicator lamp does not go out after starting the 
engine, the adjustable steering column is not locked 
properly.

the steering column.
Wa r n i n g !

indicator lamp comes on when the engine is

we recommend that you have the 
malfunction checked as soon as possible, see

Adjusting clock (instrument cluster activated):
Minute: Pull out knob (2) and turn it to the right.
Hour: Pull out knob (2) and turn it to the left.
Coolant temperature gauge (1)
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 (2)
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 (11)
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.
