Practical advice
Jump-starting
If the battery is discharged, the engine can
be started from another vehicle using jump
leads. Forim proved accessibility, your ve-
hicle has been fitted with a positive and
negative contact in the eng ine compart-
ment.
Please note:
! Jump-starting must only be performed
when the engine and catalytic convert-
er are cold.
! Do not start the engine if the battery
has frozen. Let th ebattery thaw out
fir st.
! Jump-starting may only be performed
from batteries with the sam enominal
vol tage.
! Use jump leads for jump -starti ng.You
can obtain further information from a
qualified speci alistw orkshop, e.g. a
Mercedes-Benz Service Centre. !
Avoid repeated and lengthy starting
at tem pts.
Never start the vehicle using a rapid battery
charger.
6 Make sure thatthe two vehicles do not
touch.

Practical advice
Towing
Comply with national regulations when
towing.
Having the vehicle carried away on a trans-
porter or trailer is pre ferable to towing it
away. We recommend the use of a rigid
towbar if towing is nec essary.
You may on lytow the vehicle a maximum
of 50 km. A maximum towing speed of
50 km /hmust not be exceeded. i
Deactivate the automatic locking while driv-
in gfunction when towi ng. You could otherwise
beco me locked out when pushi ngortowing the
vehicle.
! Vehicles wit hautomatic transmission
must not be tow-started.
! If th eengine does not start, try jump-
starting it ( =page 379).
! If the vehicle does not start after
jump-starting, have it towed to a quali-
fied specialist work shop, e.g. to a
Mercedes-Benz Service Centre.
! If the vehicle is to be towed for a longer
distance, only tow it with the rear axle
raised. !
If the vehicle has suffere dtransmission
damage, only tow it with the propeller
shaft disconnected.
! Before tow ing the vehicle, make sure
the battery isconnected and charged.
Otherwise, you will not be able to
switch on the ignition and will have
no steering and braki ngassistance.
! Shift the transmission to position N. Opening the front cover
The fixing points for the bolt-on towing eye
are located in the bumpers. They are locat-
ed under the cover on the right-hand side
when
viewed in the direction of travel both
at the front and the rear.
! Only secure the tow cable or towbar to the
towing eye.The vehicle could otherwi sebe
damaged. Towing
G
Risk of accident Tow the vehicle using a rigid
towbar if:
! the engine will not start
! there is a malfunction in the power sup-
ply or the vehicle's electrical sy stem
There is no power assistance for the steer-
ing when the engine is not running. Signifi-
ca ntly greater force is then needed to steer
the vehicle and to brake.
When towing or tow-starting another vehi-
cle, its weight should not be greater than the
permissible gross weight of your ve hicle. Po
ints to bear in mind Fitting the towing eye209en_d2.boo Seite

390 Technical data
Genuine Mercedes-Benz parts
The "Technical data" section contains all
the necessary technical data for your vehi-
cle. Some of the values given are provi-
sional and, in some cases, calculated
values. Final
values were not available
when this manual was printed.
i The technical data was determined in ac-
co rdance with EU Directives. All data applies to
the vehicle's standard equipment. The data may
therefore differ for vehicles with optional equip-
me nt. You may obtain further information from a
Me rcede s-Be nz Service Cen tre.
You will find information ab out your vehicle's
noise level in th evehicle 'sdoc umen tation.
Mercedes-Benz tests genuine parts and
con version parts and accessories whi ch
have been speci fically approved for your
veh icle in terms of their reliability, safety
and suitab ility.
Despite ongoing market research,
Mercedes-Benz is unable to guarantee oth-
er parts. Mercedes-Benz therefore accepts
no responsi bility for the use of such parts
in Mercedes-Benz vehicles, even if they
have been independently or officially ap-
proved. In Germany and other countries, certain
parts are only officially approv
edfor instal-
lation or modification work ifthey comply
with legal requirements. All genuine
Mercedes-Benz parts satisfy these
regul ations.
Make sure thatreplacement parts are suit-
able for you rvehicle. In many countries,
parts that constitute a modification tothe
vehicle could invalidate the vehicle's gen-
eral operating permit. This isthe case if:
! ther e is achan gein the vehicle type ap-
proved in the general operating permit
! road users could be endangered
! exhaust emissions or noise levels are
adversely affected
The use of parts wh ich have not been offi-
cially approve dcan jeopardise the safety
of your vehicle.
Mercedes-Benz therefore recommends
that you use genuine Mercedes-Benz parts
and conversion parts and accessories
whi chhave been approved for your vehi-
cle. You can obtain genuine Merce
des-Benz
parts and appro ved conversion parts and
accessories from any Merced es-Benz
Service Centre. Here you will receive ad-
vi ce about technical modifications, and the
parts will be pro fessionally fitted.
Always quote the vehicle identification
number and the engine number when or-
dering genuine parts. You will find these
numbers onthe vehicle data card in the
"Service Booklet" or on your vehicle's iden-
tification plates ( =pa ge 393). Genuine Mercedes

Environmental note DaimlerChrysler also supplies reconditioned
assemblies and parts which are of the same
quality as new parts. These parts have the
same warranty as new parts. 209en_d2.boo Seite

Ve hicle el ectron ics
! Only have th eengine electronics and asso-
ciated parts, such as control units, sensors or
connec tor leads, serviced at a qualified spe cial-
is tworkshop. Otherwise, vehicle parts may wear
more quickly and the vehicle warranty and gen-
eral operating permit may be invalidated. Electrical and electronic equipment can
jeopardise the operational safety of your
vehicle. If equipment of th iskind is retrofit-
te d, it must be typ eappro vedand must
bear the emark .The emark can be ob-
tained from the equipment manufacturer
or an authorised testing authority.
If you wish to install telephones or two-way
radios in the vehicle, you must obtain for-
mal approval. Mercedes-Benz approves
the installation of mobile telephones and
two-w ayradios provide dthat they are in-
stalled professionally and a low-reflection
exterior aerial is used.
The transmission output of the telephone
or two-way radio must not exceed the max-
imum transmission outputs specif ied on
the next page. Vehicle electronics

sumption
The vehicle will use more fuel than usual in
the following conditions:
! at very low temperatures
! in urban traffic
! on short trips
! when to wing a trailer
! in mountainous terrain
The consumption figures were determined
in acco rdan ce with EUDirec tive
19 99 /1 00/E C under the following
test conditions:
! Urban driv ing conditions are simulated
by frequent pulling awayand stopping.
! Extra-urban dr iving con ditions are sim-
ulated by accelerating from 0 to
120 km /husing all gears.
! Total fuel consumption is cal culated
us ing a weighting of approximately 37%
for urb andriving and approxi mately
63% for extra-urban driv ing. i
The act ual consumption value sof your vehi-
cl ema y deviate from the values given depending
on:
! Driving style
! Road and traffic conditions
! Environmental influences
! Vehicle's operating state
Mercedes-Benz isconstantly updating its
vehicles to the state of the art. Depending
on when the Owner's Manual went to print,
it may be that the current consumption val-
ues are lower than those listed inthe fol-
lowing table. The current consumption
val ues can be found in the COC papers (EC
CE RTIFICATE OF CONFORMITY). These pa-
pers are supplied when the veh icle is deliv-
ered. !Donotuse fuel addi tives. These couldlead
to increased wear and engine damage. If youuse
