Restraint systems
Te ch n ica l
data Instruments

cluster displayPractical hints Car care Index 3Side impact airbag
The side impact airbags are located in the doors.
The most effective occupant restraint system yet 
developed for use in production vehicles is the seat belt. 
In some cases, however, the protective effect of a seat 
belt can be further enhanced by an airbag.
In conjunction with wearing the seat belts, the driver 
and front passenger airbags can provide increased 
protection for the driver and front passenger in certain 
frontal impacts exceeding preset thresholds. Door mounted side impact airbags can provide increased 
protection to belted front passengers on the impacted 
side of the vehicle in side impacts exceeding its preset 
threshold.
Important!
The operational readiness of the airbag system is 
verified by the indicator lamp “SRS” in the instrument 
cluster when turning the electronic key in steering lock 
to position 1 or 2. If no fault is detected, the lamp will go 
out after approximately 4 seconds; after the lamp goes 
out, the system continues to monitor the components 
and circuitry of the airbag system and will indicate a 
malfunction by coming on again. 
The following system components are monitored or 
undergo a self-check: crash-sensor(s), airbag ignition 
circuits, front seat belt buckles, emergency tensioning 
retractors, seat sensor.

P91.60-2122-26
Initially, when the electronic key is turned from steering 
lock position 0 to positions 1 or 2, malfunctions in the 
crash-sensor are detected and indicated (the “SRS” 
indicator lamp stays on longer than 4 seconds or does 
not come on).
Have the system checked at your authorized 
Mercedes-Benz Center immediately.

Manually adjust the mirror.
Use your inside mirror to determine the size and 
distance of objects seen in the passenger side convex 
mirror.
Antiglare night position
With the electronic key in steering lock position 2, the 
mirror reflection brightness responds to changes in 
light sensitivity.
With gear selector lever in position “R”, or with the 
interior lamp switched on, the mirror brightness does 
not respond to changes in light sensitivity.Note:
The automatic antiglare function does not react, if 
incoming light is not aimed directly at sensors in the 
mirror.
Wa r n i n g !
In the case of an accident liquid electrolyte may 
escape the mirror housing when the mirror glass 
breaks.Electrolyte has an irritating effect. Do not allow the 
liquid come into contact with eyes, skin, clothing, 
or respiratory system. In cases it does, immediately 
flush affected area with water, and seek medical 
help if necessary.

Coolant temperature gauge (3)
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.Outside temperature indicator (5)
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!
• 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.
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.

I Intermittent wiping 
(optional rain sensor: One initial wipe, pauses 
between wipes are automatically controlled by a 
rain sensor monitoring the wetness of the 
windshield.)
Notes:
With switch in this position, one wipe occurs 
when turning the electronic main key in steering 
lock from position 0.
Optional rain sensor: 
Do not leave in intermittent setting when vehicle 
is taken to an automatic car wash or during 
windshield cleaning. Wiper will operate in 
presence of water spray at windshield, and wiper 
may be damaged as a result.

Catalytic converter
Your Mercedes-Benz is equipped with monolithic type 
catalytic converters, an important element in 
conjunction with the oxygen sensors to achieve 
substantial control of the pollutants in the exhaust 
emissions. Keep your vehicle in proper operating 
condition by following our recommended maintenance 
instructions as outlined in your Service Booklet.Caution!
To prevent damage to the catalytic converters, use only 
premium unleaded gasoline in this vehicle.
Any noticeable irregularities in engine operation should 
be repaired promptly. Otherwise, excessive unburned 
fuel may reach the catalytic converter causing it to 
overheat, which could start a fire.
Wa r n i n g !
As with any vehicle, do not idle, park or operate 
this vehicle in areas where combustible materials 
such as grass, hay or leaves can come into contact 
with the hot exhaust system, as these materials 
could be ignited and cause a vehicle fire.
