Te ch n ica l
data Instruments
and controlsOperationDrivingInstrument
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.

Driving instructions
Drive sensibly - Save fuel
Fuel consumption, to a great extent, depends on driving
habits and operating conditions.
To save fuel you should:
• keep tires at the recommended inflation pressures,
• remove unnecessary loads,
• allow engine to warm up under low load use,
• avoid frequent acceleration and deceleration,
• have all maintenance work performed at regular
intervals by an authorized Mercedes-Benz Center.
Fuel consumption is also increased by driving in cold
weather, in stop-and-go traffic, on short trips and in hilly
country.Drinking and driving
Pedals
Wa r n i n g !
Drinking or taking drugs and driving can be a very
dangerous combination. Even a small amount of
alcohol or drugs can affect your reflexes,
perceptions and judgement.The possibility of a serious or even fatal accident is
sharply increased when you drink or take drugs
and drive.Please don’t drink or take drugs and drive or allow
anyone to drive after drinking or taking drugs.Wa r n i n g !
Keep driver’s foot area clear at all times. Objects
stored in this area may impair pedal movement.
