Driving instructions
Driving instructions
Drive sensibly – save fuel
Fuel consumption, to a great extent, de-
pends on driving habits and operating con-
ditions.
To save fuel you should:
Keep tires at the recommended infla-
tion pressures.
Remove unnecessary loads
Allow engine to warm up under low 
load use.
Avoid frequent acceleration and decel-
eration.
Have all maintenance work performed 
at the intervals specified in the Service 
Booklet and as required by the FSS. 
Contact an authorized Mercedes-Benz 
Center.
Fuel consumption is also increased by driv-
ing in cold weather, in stop-and-go traffic, 
on short trips and in hilly country.
Drinking and driving
Pedals
Warning!
G
Drinking and driving and/ or taking drugs 
and driving are a very dangerous combina-
tion. Even a small amount of alcohol or 
drugs can affect your reflexes, perceptions 
and judgement.
The possibility of a serious or even fatal ac-
cident are greatly increased when you drink 
or take drugs and drive.
Do not drink or take drugs and drive or allow 
anyone to drive who has been drinking or 
taking drugs.
Warning!
G
Keep driver’s foot area clear at all times. Ob-
jects stored in this area may impair pedal 
movement.

If there is excess engine oil with the engine 
at normal operating temperature, the 
following message will appear:Engine oil level
Reduce oil level!

Unscrew filler cap1 from filler neck.
!Excess oil must be siphoned or drained 
off. It could cause damage to the 
engine and catalytic converter not 
covered by the Mercedes-Benz Limited 
Warranty.
!Only use approved engine oils. For a 
listing of approved engine oils, refer to 
the Factory Approved Service Products 
pamphlet in your vehicle literature port-
folio.
In addition, check the oil filler cap for 
important information pertaining to the 
engine oil needing to meet a specific 
Mercedes-Benz specification (e.g. MB 
229.5). If such information is printed 
on the oil filler cap, only use an engine 
oil from the list of approved engine oils 
in the Factory Approved Service Prod-
ucts pamphlet that meets the specifi-
cation indicated on the oil filler cap.  
Using engine oils of other specification 
may cause the FSS to incorrectly deter-
mine the next service interval and will 
result in engine damage not covered by 
the Mercedes-Benz Limited Warranty.

260 OperationEngine compartmentBattery
Your vehicle is equipped with two batter-
ies:
The starter battery (located in the en-
gine compartment)
The battery for electrical consumers 
(located in the trunk)
These batteries should always be suffi-
ciently charged in order to achieve their 
rated service life. Refer to Service Booklet 
for battery maintenance intervals.
If you use your vehicle mostly for 
short-distance trips, you will need to have 
the battery charge checked more frequent-
ly. 
When replacing batteries, always use bat-
teries approved by Mercedes-Benz. 
If you do not intend to operate your vehicle 
for an extended period of time, consult an 
authorized Mercedes-Benz Center about 
steps you need to observe.Batteries contain materials that can harm 
the environment if disposed of improperly. 
Recycling of batteries is the preferred 
method of disposal. Many states require 
sellers of batteries to accept old batteries 
for recycling.
G
Observe all safety instructions 
and precautions when handling 
automotive batteries.
