cluster displayPractical hints Car care Index Notes:
If the symbols : and I are continuously
illuminated after pressing button (1) twice and there is
no change in the odometer display field or the low
engine oil level warning lamp comes on, a malfunction
has occurred to the system. Perform the engine oil level
check with the dipstick.
If no oil leaks are noted continue to drive to the nearest
Mercedes-Benz Center to have the system checked.
Observe the engine oil temperature gauge.
Fuel consumption gauge
While driving, instantaneous fuel consumption is
indicated in miles per gallon (mpg), or in Canada liters
per 100 kilometers (l/100 km).
With the engine switched off, the needle reads “0”.
Due to system design, minimum consumption is
indicated at idle speed.Engine oil temperature gauge
Normal operating engine oil temperatures are from
175°F (80°C) to 250°F (120°C).
During severe operating conditions and stop-and-go
traffic, the engine oil temperature may rise close to the
red marking.
The engine should not be operated with the engine oil
temperature in the red zone. Doing so may cause
serious engine damage which is not covered by the
Mercedes-Benz Limited Warranty.
When the engine oil temperature is close to the red
marking, relieve the load on the engine by decreasing
vehicle speed to lower engine oil temperature.
Once the engine oil temperature returns to the normal
temperature range, the engine oil level should be
checked. See page 82 or 222.
Engine oil consumption
Engine oil consumption checks should only be made
after the break-in period. During the break-in period,
higher oil consumption may be noticed and is normal.
Frequent driving at high engine speeds results in
increased consumption.

When the vehicle is parked on the street the standing
lamps (right or left side parking lamps) can be turned
on, making the vehicle more visible to passing vehicles.
The standing lamps cannot be operated with the key in
steering lock position 2.
Daytime running lamp mode
When the engine is running and the selector lever is in
a driving position, the low beam headlamps (includes
parking lamps, side marker lamps, taillamps and
license plate lamps) are automatically switched on.
When shifting from a driving position to position “N”
or “P”, the low beam switches off (2 seconds delay).
For nighttime driving the exterior lamp switch should
be turned to position B to permit activation of the
high beam headlamps.Night security illumination
When exiting the vehicle after driving with the exterior
lamps on, they switch on again for added illumination
for approximately 30 seconds after closing the last door.
The lamp-on time period can be changed at your
Mercedes-Benz Center.

monitoring the wetness of the windshield.
Notes:
With switch in this position, one wipe occurs
when turning the key in steering lock from
position 0.
Do not leave in intermittent setting when vehicle
is taken to an automatic car wash or during

Basic mode:
None of the push-buttons (6 or 7) is pressed.
8Display and controls, see page 92The system is always at operational readiness, except
when manually switched off.
The automatic climate control only operates with the
engine running.
The temperature selector should be left at the desired
temperature setting. The temperature selected is
reached as quickly as possible.
The system will not heat or cool any quicker by setting a
higher or lower temperature.
The automatic climate control removes considerable
moisture from the air during operation in the cooling
mode. It is normal for water to drip on the ground
through ducts in the underbody.
Important!
This vehicle is equipped with an air conditioner system
that uses R-134a (HFC: hydrofluorocarbon) as a
refrigerant. Repairs should always be performed by a
qualified technician, and refrigerant should be collected
in a recovery system for recycling.

Air recirculation
This mode can be selected to temporarily reduce the
entry of annoying odors or dust into the vehicle’s
interior.
Outside air is not supplied to the car’s interior.
To select, press O button.
To cancel, press O button again.
The system will automatically switch from recirculated
air to fresh air:
• after approx. 5 minutes at outside temperatures
below approx. 40°F (5°C),
• after approx. 30 minutes, at outside temperatures
above approx. 40°F (5°C),
• after approx. 5 minutes, if button S is pressed.
Notes:
If the windows should fog up from the inside, switch
from recirculated air back to fresh air.
At high outside temperatures, the system automatically
engages the recirculated air mode thereby increasing
the cooling capacity performance, switching to partially
fresh air within 20 minutes.Residual engine heat utilization
With the engine switched off, it is possible to continue
heating the interior for a short while.
Air volume and distribution are controlled
automatically.
To select:
Turn electronic key in steering lock to position 1 or 0 or
remove electronic key.
Press T button.
This function selection will not activate if the battery
charge level is insufficient.
To c a n c e l :
Press T button.
The system will automatically shut off:
• If you turn electronic key in steering lock to
position 2,
•after approx. 30minutes,
• if the battery voltage drops.
