235 Operation
Driving instructions
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 tire
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 the intervals specified in the
Maintenance Booklet and as required
by the maintenance service display.
Contact 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 area.
Drinking and driving
Pedals
Warning!
G
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgment.
The possibility of a serious or even fatal
accident 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
Make sure that absolutely no objects are ob-
structing the pedals’ range of movement.
Keep the driver’s footwell clear of all obsta-
cles. If there are any floormats or carpets in
the footwell, make sure that the pedals still
have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents
and/or injury.

256 OperationTrunkBatteries
Your vehicle is equipped with two
batteries:

Starter battery in the trunk


Consumer battery in the trunk
These batteries should always be suffi-
ciently charged in order to achieve its rat-
ed service life. A flat battery must be fully
recharged. Refer to Maintenance 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
frequently.
When replacing batteries, always use bat-
teries approved by Mercedes-Benz. Have
this work only carried out by an authorized
Mercedes-Benz Center.
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.For more information on battery mainte-
nance, see “Batteries” (
page 370).
Warning!
G
Observe all safety instructions and precau-
tions when handling automotive batteries.
Risk of explosion.
Fire, open flames and smoking
are prohibited when handling
batteries. Avoid creating sparks.
Battery acid is caustic. Do not
allow it to come into contact
with skin, eyes or clothing.
Wear suitable protective cloth-
ing, especially gloves, apron and
faceguard.
Wear eye protection.
Rinse any acid spills immediate-
ly with clear water. Contact a
physician if necessary.
Keep children away.
Follow the instructions in this
Operator’s Manual.
!
You must not jump start the vehicle, other-
wise the vehicle electrical systems could be
damaged.

294 OperationMaintenanceIn order to maintain the performance and
safety of your vehicle, we strongly recom-
mend that you have your vehicle serviced
by an authorized Mercedes-Benz Center,
every 12 months, even if the vehicle has
covered less than 10 000 miles
(15 000 km) in that time.
The maintenance service indicator will
notify you when the next maintenance ser-
vice is due within the next 12 months or
10 000 miles (15 000 km), whichever
comes sooner.Before the next maintenance service is
due, one of the following messages will ap-
pear in the right multifunction display while
you are driving or when you switch on the
ignition:
Service In .. Days
Service In .. Miles

When the maintenance service is due, the
following message appears in the multi-
function display:
Service Due Now
Clearing the maintenance service indicator message
The maintenance service indicator mes-
sage is automatically cleared after 30 sec-
onds when you switch on the ignition. You
can also clear it yourself.
1Reset button
Press reset button 1.
The maintenance service indicator
message is cleared and the standard
display appears in the multifunction
display (
page 117).
!
Failure to have the vehicle maintained in ac-
cordance with the Maintenance Booklet and
maintenance service indicator at the designated
times/mileage will result in vehicle damage not
covered by the Mercedes-Benz Limited
Warranty.
!
Excessive load on the brake system causes
increased wear of brake pads and brake disks. If
the brake pads have to be replaced multiple
times within one maintenance service interval,
the brake disks must be checked. Observe the
information given in the Maintenance Booklet
and contact an authorized Mercedes-Benz
Center.

There are malfunctions, but the
electro-hydraulic brake system
is operating normally.

Contact an authorized Mercedes-Benz Center
immediately.

Parking Brake
You are driving with the parking
brake set.

Release the parking brake (

Brake Wear
The brake pads have reached
their wear limit.

Have the brake pads replaced as soon as pos-
sible.
!
Brake pad thickness must be visually
checked by a qualified technician at the intervals
specified in the Maintenance Booklet.
Excessive load on the brake system causes in-
creased wear of brake pads and brake disks. If
the brake pads have to be replaced multiple
times within one maintenance service interval,
the brake disks must be checked. Observe the
information given in the Maintenance Booklet
and contact an authorized Mercedes-Benz
Center.
Warning!
G
Have brake pad replacement and other work
on the electro-hydraulic brake system car-
ried out by qualified technicians only. Con-
tact your Mercedes-Benz Center for further
information. The electro-hydraulic brake
system must be deactivated prior to working
on the system. High pressure is intermit-
tently built up in the system as part of its
automatic self-test. In addition, the system
is automatically activated when the vehicle
is unlocked by remote control, when the
driver or passenger door is opened, when
the SmartKey in the starter switch is turned
to position1, when the brake pedal is
depressed or when the parking brake is
released.
Failure to deactivate the system prior to
maintenance will cause brake pistons to
extend and brake fluid to leak, which may
result in injuries (contusions and acid
burns), see “Electro-hydraulic brake sys-
tem” (
page 87).

395 Technical data

specification other than those expressly re-
quired for the Maintenance System, or changing
of oil and oil filter at change intervals longer than
those called for by the Maintenance System will
result in engine or emission control system dam-
age not covered by the Mercedes-Benz Limited
Warranty.

dations for scheduled oil changes. Failure to do
so will result in engine or emission control sys-
tem damage not covered by the Mercedes-Benz
