General notes
Important safety notes G
WARNING
If you switch off th eignitio nwhile driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect.Y ou will require considerably
more effort to steer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If you operate mobile communication
equipment while driving, you will be
distracted from traffic conditions. You could
also lose control of the vehicle. There is arisk
of an accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements for the
country in which you are driving. Some
jurisdiction sprohibit the driver from using a
mobile phone while driving avehicle.
If you make acall while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are unsure, pull over to
asafe location and stop
before operating the telephone.
Bear in mind that at aspeed of only 30 mph
(approximately 50 km/h) ,the vehicle covers
ad istance of 44 ft (approximately 14 m) per
second.
Drive sensibly –save fuel Observe the following tips to save fuel:
R The tires should always be inflated to the
recommended tire pressure.
R Remove unnecessary loads.
R Remove roof racks whe nthey are not
needed.
R Warm up the engine at low engine speeds.
R Avoid frequent acceleration or braking.
R Have all maintenancew ork carried out as
indicated by the service intervals in the
MaintenanceB ooklet or by the service
interval display.
Fuel consumption also increases when
driving in cold weather, in stop-start traffic
and in hilly terrain.
Drinking and driving G
WARNING
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even asmall amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment.
The possibility of aserious or even fatal
accident is greatly increased when you drink

the engin erunning in enclosed spaces
without sufficient ventilation.
Certain engin esystems are designed to keep
the level of poisonous component sinexhaust
fumes within legal limits.
These systems only work at peak efficienc yif
the yare serviced exactly in accordance with
the manufacturer' sspecifications .For this
reason ,only have work on the engin ecarried

The engin esettings must not be changed
under any circumstances. Furthermore, all
specific service work must be carried out at
regular intervals and in accordance with the
Mercedes-Ben zservice requirements. Details
can be found in the Maintenance Booklet. ECO display
The ECO display gives you information on how
economical your driving style is. The ECO
display assists you in achieving the optimum
driving style in term sofconsumption ,taking
the actual and selected conditions into
consideration .Your driving style can
significantly influence the vehicle's
consumption. Example: ECO display (color multifunction display)
The ECO display consist softhree bars:
R Acceleration R
Constant R
Coasting The percent value is the average value of the
three bars. The three bars and the mean value
begin at the value of 50%. Ahigher percentage indicates
amoree conomical
driving style.
The ECO display doe snot indicate the actual
fue lconsumption and afixe dp ercentage
count in the ECO display doe snot indicate a
fixe dconsumption figure.
Apart from driving style, consumption is
dependent on many factors such as ,e.g.:
R load
R tire pressure
R cold start
R choice of route
R electrical consumers switched on
These factors are not taken into
consideration by the ECO display.
The evaluation of your driving styl eiscarried
ou tu sing the following three categories:
R Acceleration (evaluation of all
acceleration processes):
- The bar fills up: moderate acceleration,
especially at higher speeds
- The bar empties: sporty acceleration
R Constant (assessment of driving behavior
at all times):
- The bar fills up: constant speed and
avoidance of unnecessary acceleration
and deceleration
- The bar empties: fluctuations in speed
R Coasting (assessment of all deceleration
processes):
- The bar fills up: anticipatory driving,
keeping your distance and early release
of the accelerator. The vehicle can coast
without use of the brakes.
- The bar empties: frequent braking
i An economical driving style specially
requires driving at moderate engine
speeds.

Servicing the brakes !
If the red brake warning lamp lights up in
the instrument cluster and you hear a
warning ton ewhile the engin eisrunning,
the brake fluid level may be too low.
Observ eadditional warning messages in
the multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked
immediately. This work should be carried
out at aqualified specialist workshop.
! Afunction or performanc etest should
only be carried out on a2-axle
dynamometer. If yo uareplanning to have
the vehicl eteste dons uchad ynamometer,
contact an authorize dMercedes-Benz
Center to obtai nfurthe rinformatio nfirst.
Otherwise, yo ucould damage the drive
trai nort he brake system.
! As the ESP ®
system operates
automatically, the engine and the ignition
must be switched off (the SmartKe ymust
be in position 0or 1in the ignition lock) if:
R the electri cparking brak eistested on a
brake dynamometer (for amaximum of
ten seconds)
R the vehicle is towed with the front axle
raised.
Braking triggered automaticallybyE SP®
may seriouslyd amage the brake system.
All checks and maintenance work on the
brake system must be carried out at a qualified specialist workshop. Consult a
qualified specialist workshop to arrange this.
Have brake pads installed and brake fluid
replaced at
aqualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the
functionality of your brakes at regular
intervals.
You can find adescription of Brake Assist
(BAS) on (Y page 64).
Mercedes-Benz recommends that you only
have brake pads/linings installed on your
vehicle which have been approved for
Mercedes-Benz vehicles or which correspond
to an equivalent quality standard. Brake
pads/linings which have not been approved
for Mercedes-Benz vehicles or which are not
of an equivalent quality could affect your
vehicle's operating safety.
Mercedes-Benz recommends that you only
use brake fluid that has been specially
approved for your vehicle by Mercedes-Benz,
or which corresponds to an equivalent quality
standard. Brake fluid which has not been
approved for Mercedes-Benz vehicles or
which is not of an equivalent quality could
affect your vehicle's operating safety.
Checking brake liningt hickness You can measure the break pad/lining
thickness using
atest gauge.C olor-coding
(green or red) on the test gauge allows you to
determin ewhether the brake pad/lining
thickness is still sufficient .The test gauge is
in the vehicle document wallet in the glove
