425 Practical hints
Jump starting

Make sure the two vehicles do not
touch.

Turn off all electrical consumers.

Apply parking brake.

Shift gear selector lever* to positionP
(manual transmission to Neutral).

Open the hood (
page 307).

Flip up cover from positive under hood
terminal2 in front of water tray1
(page 422).1Positive terminal of charged battery
2Positive under hood terminal in front of
water tray
3Negative under hood terminal in front
of water tray
4Negative terminal of charged battery

Connect positive terminal1 of the
charged battery with positive under
hood terminal2 in front of the water
tray with one jumper cable. Clamp the
cable to positive terminal1 of the
charged battery first.

Start the engine of the vehicle with the
charged battery and run at idle speed.

Connect negative terminal4 of the
charged battery with negative under
hood terminal3 in front of the water
tray with the second jumper cable.
Clamp the cable to negative
terminal4 of the charged battery
first.

Start the engine of the disabled vehi-
cle.
You can now turn on the electrical con-
sumers. Do not turn on the lights under
any circumstances.

Remove the jumper cables first from
negative terminals3 and4 and then
from positive terminals2 and1.
You can now turn on the lights.

Have the battery checked at the near-
est authorized Mercedes-Benz Center.
Warning!
G
Keep flames or sparks away from battery.
Do not smoke.
Observe all safety instructions and precau-
tions when handling automotive batteries
(page 314).
!Never invert the terminal connections.
iVehicles with automatic transmission*:
Do not tow-start vehicle.

426 Practical hintsTowing the vehicleMercedes-Benz recommends that the vehi-
cle be transported with all wheels off the
ground using flatbed or appropriate wheel
lift/dolly equipment.When circumstances do not permit the
recommended towing methods, the vehi-
cle may be towed with all wheels on the
ground or front wheels raised only so far as
necessary to have the vehicle moved to a
safe location where the recommended
towing methods can be employed.
!Vehicles with automatic transmission*:
Do not tow-start vehicle.!Use flatbed or wheel lift/dolly equip-
ment with the SmartKey in the starter
switch in position0.
Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
To prevent damage during transport,
do not tie down vehicle by its chassis or
suspension parts.
Switch off the tow-away alarm
(page 88) and the automatic central
locking (
page 101).
!To be certain to avoid a possibility of
damage to the transmission, however,
we recommend the drive shaft be dis-
connected at the rear axle drive flange
for any towing beyond a short tow to a
nearby garage.
!If the vehicle is towed with the front
axle raised, the engine must be shut off
(SmartKey in starter switch
position0or1). Otherwise, the ESP
®
will immediately be engaged and will
apply the rear wheel brakes.
When towing the vehicle with all wheels
on the ground, the gear selector lever*
must be in positionN (manual trans-
mission: gear shift lever in neutral posi-
tion) and the SmartKey must be in
starter switch position1.
When towing the vehicle with all wheels
on the ground or the front axle raised,
the vehicle may be towed only for dis-
tances up to 30 miles (50 km) and at a
speed not to exceed 30 mph
(50 km/h).

427 Practical hints
Towing the vehicle
Warning!
G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:

the engine will not run


there is a malfunction in the power sup-
ply or in the vehicle’s electrical system
as that will be necessary to adequately con-
trol the towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make sure the SmartKey is in
starter switch position2.
If the SmartKey is left in starter switch
position0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock, re-
move SmartKey from starter switch and re-
insert.
Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the ve-
hicle. Adapt your driving accordingly.iTo signal turns while being towed with
the hazard warning flasher in use,
switch on ignition and activate the
combination switch for the left or right
turn signal in the usual manner – only
the selected turn signal will operate.
Upon canceling the turn signal, the haz-
ard warning flasher will operate again.
!When towing the vehicle with all wheels
on the ground, please note the follow-
ing:
With the automatic central locking acti-
vated and the SmartKey in starter
switch position2, the vehicle doors
lock if the left front wheel as well as the
right rear wheel are turning at vehicle
speeds of approx. 9 mph (15 km/h) or
more.
To prevent the vehicle door locks from
locking, deactivate the automatic cen-
tral locking (
page 101).
Switch off the tow-away alarm
(
page 88).
The vehicle should only be towed using
a properly installed towing eye bolt.
Never attach a tow cable, tow rope or
tow rod to the vehicle chassis, frame or
suspension parts.

430 Practical hintsFusesFuses are designed to protect the electri-
cal circuits in your vehicle from a short cir-
cuit. If a fuse is blown, the component(s)
and systems secured by that fuse will stop
working.
The following aids are available to help you
replace fuses:

Fuse chart


Spare fuses


Fuse extractor
The electrical fuses are located in different
fuse boxes:


Main fuse box in passenger compart-
ment (
page 431).


Fuse box in engine compartment
(page 432).
Aids for replacing fuses
Fuse chart
The fuse chart is located in the main fuse
box in the passenger compartment
(page 431). The amperages of the fuses
are also given there.
Spare fuses
Spare fuses are located in the vehicle tool
kit in the spare wheel well (
page 388).
Fuse extractor
The fuse extractor is located in the vehicle
tool kit in the spare wheel well
(
page 388).
Warning!
G
Only use fuses approved by Mercedes-Benz
with the specified amperage for the system
in question. Using other fuses may cause an
overload and leading to a fire, and/or cause
damage to electrical components and/or
systems.
!Never attempt to repair or bridge a
blown fuse. Have the cause determined
and remedied by an authorized
Mercedes-Benz Center.!Keep the fuse boxes free by contamina-
tion and wetness. Otherwise, electrical
parts or systems could be damaged.

Engine oils
Engine oils are specifically tested for their
suitability in our engines and durability for
our service intervals. Therefore, only use
approved engine oils and oil filters re-
quired for vehicles with Maintenance
System (U.S. vehicles) or FSS PLUS (Cana-
da vehicles). For a listing of approved en-
gine oils and oil filters, refer to the Factory
Approved Service Products pamphlet, or
contact an authorized Mercedes-Benz
Center.
Engine oil additives
Do not blend oil additives with engine oil.
They may damage the engine. Damage or
malfunctions resulting from blending oil
additives are not covered by the
Mercedes-Benz Limited Warranty.Air conditioning refrigerant
R-134a (HFC) refrigerant and special
PAG lubricating oil are used in the air con-
ditioning system. Never use R-12 (CFC) or
mineral-based lubricating oil, otherwise
damage to the system will occur.
Brake fluid
During vehicle operation, the boiling point
of the brake fluid is continuously reduced
through the absorption of moisture from
the atmosphere.
Only brake fluid approved by
Mercedes-Benz is recommended. Your au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.
!Using engine oils and oil filters of spec-
ification other than those expressly re-
quired for the Maintenance System
(U.S. vehicles) or FSS PLUS (Canada
vehicles), or changing of oil and oil filter
at change intervals longer than those
called for by the Maintenance System
(U.S. vehicles) or FSS PLUS (Canada
vehicles) will result in engine damage
not covered by the Mercedes-Benz
Limited Warranty.
Please follow Maintenance System
(U.S. vehicles) or FSS PLUS (Canada
vehicles) recommendations for sched-
uled oil changes. Failure to do so will
result in engine damage not covered by
the Mercedes-Benz Limited Warranty.
Warning!
G
Under extremely strenuous operating condi-
tions, this moisture content can lead to the
formation of bubbles in the system, thus re-
ducing the system’s efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s
Maintenance Booklet for replacement
interval.
