Protecting the environment

Protecting the environment

Natural resources form the basis of our
existence on this planet. The objectives of
our policy are for these resources to be used
sparingly and in a manner which takes the
requirements of both nature and humanity
into account.

Our declared policy is integrated
environmental protection. This policy starts
at the root causes and encompasses in its
management decisions all the consequences
for the environment which could arise
from production processes or the products
themselves.

You too can help to protect the environment
by operating your Mercedes-Benz in an
environmentally responsible manner.

Operating conditions and your individual
driving style to a large extent influence fuel
consumption and the rate of engine, brake,
and tire wear. To reduce fuel consumption
and the rate of wear, please consider the
following:

A regularly serviced vehicle will also help
protect the environment. You should adhere
to the service intervals displayed by the
Mercedes-Benz Maintenance System service
indicator, along with other maintenance
work described in this booklet.

We recommend that you have services
performed by your authorized Mercedes­Benz Dealer using Genuine Mercedes-Benz
parts.

• Avoid short trips.

• Make sure that the tire pressures are
always correct.

• Avoid frequent, abrupt acceleration.

• Do not carry any unnecessary weight.

• Remove ski holders and roof racks once
you no longer need them.

• Do not warm up the engine with the
vehicle stationary.

• Shift gears such that each gear is used
only up to 2/3 of its maximum engine
speed.

• Keep an eye on the vehicle’s fuel
consumption.

Introduction

Introduction

Mercedes-Benz Maintenance System

Your Mercedes-Benz comes equipped with
the Mercedes-Benz Maintenance System.
The Maintenance system tracks distance
driven and the time elapsed since your last
service. In addition, it calculates service
items that need to be performed and other
required maintenance work. The next
necessary maintenance service is indicated

Service Booklet

in the multifunction display in the instrument
cluster.

Approximately 1 month before a
maintenance service is due, a message
appears in the multifunction display. The
message provides the remaining kilometres
or days until the next maintenance service
is due.

The maintenance services will be indicated
by showing a service type A through type H
in the multifunction display. Types A through
H are classified based on the estimated time
needed to perform the maintenance service,
ranging from up to approximately one hour
(type A) to up to approximately eight hours
(type H).

A descriptive listing of the service items are
contained in this booklet starting on e page

16. Following each maintenance service,
your authorized Mercedes-Benz Dealer
will reset the Mercedes-Benz Maintenance
System service indicator by confirming the
service items performed.

The authorized Mercedes-Benz Dealer
performing the required maintenance
services will confirm using the Confirmation
pages in this booklet (e page 25) the work
has been carried out.

We continuously strive to improve our
product and ask for your understanding that
we reserve the right to make changes in the
periodic maintenance work which is required
for our vehicles.

The information in this manual is accurate
as of the editorial date. At the time of your
scheduled maintenance appointments with
your authorized Mercedes-Benz Dealer,
the most current maintenance work
information will be utilized for your vehicle’s
age or kilometres. Please check with your
authorized Mercedes-Benz Dealer for any
changes to the periodic maintenance work
required for your vehicle.

C/CLS/E/GLK/SLK ONLY
Maintenance services will be indicated by
showing types A or B in the multifunction
display. The service type displayed
indicates whether a Minor (A) or Major
(B) service is required (e pages 16, 18)
and is based on distance driven and time
elapsed since the last service.

When scheduling a service appointment
with your authorized Mercedes-Benz Dealer,
always indicate the service type that
appears in the multifunction display. This will
help the authorized Mercedes-Benz Dealer
to schedule your vehicle maintenance in the
most efficient manner.

GWarning! Please make sure you read the technical documentation, such as the Operator’s Manual and

workshop information, before carrying out any maintenance work.

! If the Mercedes-Benz Maintenance

System maintenance service counter was
inadvertently reset, have an authorized
Mercedes-Benz Dealer correct it. Please
only reset if the proper maintenance service
has been performed. Resetting the system
without performing the proper maintenance
service will result in engine and/or other
vehicle damage not covered by the Mercedes­Benz Limited Warranty.

Introduction

Please note any maintenance work
not performed or not performed at the
specified interval which results in the
failure of the warranted component(s) or
system(s) in question may not be covered
by the Mercedes-Benz New Vehicle Limited
Warranty.

Tire rotation

Your vehicle’s tires are a critical component
to overall vehicle performance and vehicle
stability. The useful life of tires will vary
and is proportional to tire type, speed
rating, ambient conditions, tire loading,
tire inflation pressure, road surfaces, and
individual driving style, among other factors.
Therefore, Mercedes-Benz recommends
regular checks for wear and proper inflation
and, if applicable to your vehicle’s tire
configuration, tire rotation.

Tire rotations can be performed on
vehicles with the same front and rear tire
dimensions. If your vehicle is equipped
with the same tire dimensions all around,
tires can be rotated by observing a front­to-rear rotation pattern that will maintain
the intended rotation (spinning) direction
of the tire (on unidirectional tires, an arrow
on the sidewall indicates the intended
rotation or spinning direction of the tire). In
some cases, such as when your vehicle is
configured with staggered size (different tire
sizes, front vs. rear), tire rotations are not
possible.

If your vehicle’s tire configuration allows
for tire rotation, tire rotation should be
performed in accordance with the tire
manufacturer’s recommended intervals, or
sooner at first signs of irregular (uneven)
tread wear. Tire manufacturer’s rotation
recommendations will necessitate a
tire rotation at least once in between
maintenance services and at every

maintenance service based on Mercedes­Benz maintenance intervals.

Tire rotations should be performed in
accordance with the tire manufacturer’s
recommendations. Please refer to the tire
pamphlet in your vehicle literature portfolio.

For your convenience, this Service Booklet
contains a tire rotation confirmation
page on which you can record the date
and kilometres when tire rotations were
performed (e page 24).

Service Booklet

Severe operating conditions

The maintenance intervals have been
determined so that the vehicle, under
normal operating conditions, should operate
properly between maintenance services.
Severe operating conditions may call for
correspondingly sooner replacement of the
following items:

• INTERIOR FILTERS

(e.g. dust filter, recirculating air filter,

activated charcoal filter or combination
filter) are replaced as called for by the
Mercedes-Benz Maintenance System.
Under severe dust conditions, or with
the Climate Control frequently operating
in the air recirculation mode, the filters
should be replaced correspondingly
sooner and changed more frequently
than as called for by the Mercedes-Benz
Maintenance System.

GWarning! Please make sure you read the technical documentation, such as the Operator’s Manual and

workshop information, before carrying out any maintenance work.

Introduction

• SPARK PLUGS

Spark plugs should be replaced according

to the specified maintenance interval.
Severe operating conditions (frequent
starting and stopping, excessive idling,
sustained fast highway driving) may
call for spark plugs to be replaced
correspondingly sooner.

• COOLANT

Coolant should be checked for the

Service Booklet

proper concentration before the start
of the winter season (or once a year in
hot regions). Have the coolant (water/
anticorrosion/antifreeze mixture)
replaced at the specified maintenance
interval for your vehicle model.

In vehicles with engine 275, the coolant

for the main circuit should be checked for
proper concentration before the start of
each winter season (or once a year in hot
regions) and replaced every 3 years. The
coolant for the low temperature circuit
should be replaced every 240,000 KM or
15 years.

• BRAKE FLUID

Brake fluid should be replaced every

two years, preferably in the spring. We
recommend that you only use brake
fluid approved by Mercedes-Benz. A
reminder for the next scheduled brake
fluid replacement is affixed in the engine
compartment.

Wear items

While the Mercedes-Benz Maintenance
System calls for inspection of certain
wear items, the system does not make
any judgment on the condition of these
wear items. Only a qualified technician
can determine if a wear item needs to be
replaced.

Replacement of coolant may be required

more frequently if coolant is not
maintained according to instructions and/
or other than approved anticorrosion/
antifreeze products for your vehicle are
being used. For instructions on coolant,
see “Coolants” in your vehicle Operator’s
Manual. For a listing of approved
anticorrosion/antifreeze products for
your vehicle, contact your authorized
Mercedes-Benz Dealer.

Description of Emission System Maintenance

Description of Emission System
Maintenance Jobs

The composition of exhaust emissions is
influenced not only by the special emission
control equipment, but also by various
engine components and their adjustments.

Therefore, emission system maintenance
must include these engine components.
Some maintenance jobs are actually only
tests. They are important however, because
they allow early detection of discrepancies

Service Booklet

which can later lead to increased exhaust
emissions. It is generally less expensive to
have such items adjusted immediately rather
than allowing them to contribute to costly
repairs. The maintenance intervals have
been determined so that the vehicle, under
normal conditions, should operate properly
between services.

Replace engine air filter

Under normal dust conditions, replace
engine air filter according to the
specifications outlined in this booklet for
your vehicle. Clean engine air filter cover and
housing prior to removal of engine air filter.
Under severe dusty operating conditions the
engine air filter element must be replaced
more frequently.

Replace fuel filter

Replace the fuel filter according to the
specifications outlined in this booklet for
your vehicle.

Check engine poly-V-belt condition

Engine oil and filter change

Change the engine oil and oil filter according
to the specifications outlined in this booklet
for your vehicle. If oil consumption should
increase, determine the cause and take
necessary corrective steps. Do not reset
the Maintenance System service indicator if
the oil is topped up or changed outside the
respective km interval or 1 year.

The poly-V-belt is subject to wear and aging.
It must be checked for cracks and wear
at every Service 2. Replace poly-V-belt if
necessary.

Replace spark plugs

Spark plugs are subject to electrode erosion
and must be replaced according to the
specified maintenance intervals, or more
frequently as may be required when subject
to severe operating conditions.

Evacuate and full up AdBlue

Fill up AdBlue® at every Service 1. Evacuate
