711 Practical hints
Towing the vehicle
Towing with front wheels raised

Vehicles with KEYLESS-GO*: Remove
the KEYLESS-GO start/stop button
from the starter switch (
page 366).

Insert the SmartKey into the starter
switch.

Switch on the ignition.

Switch off the automatic central lock-
ing (
page 363).

Depress the brake pedal.

Shift the automatic transmission to
neutral positionN.

If engaged, manually release the
electronic parking brake.

Switch off the ignition and leave the
SmartKey in the starter switch.
Warning!
G
When leaving the SmartKey or SmartKey
with KEYLESS-GO* in the starter switch, do
not leave children unattended in the vehicle.
It is possible for children to switch on the
ignition which could result in unsupervised
use of vehicle equipment. Unsupervised use
of vehicle equipment could result in an
accident and/or serious personal injury.
!
Keep in mind that it is important for the
SmartKey to be left in starter switch with the ig-
nition switched off. As soon as the SmartKey is
removed from the starter switch the automatic
transmission will shift to park positionP.
!
Make sure that the ignition is switched off.
If the starter switch is in position2, active brak-
ing action through the ESP
® may otherwise seri-
ously damage the brake system.
!
The vehicle may be towed only for distances
up to 30 miles (50 km) and at a speed not to ex-
ceed 30 mph (50 km/h).

712 Practical hintsTowing the vehicleTowing with all wheels on the ground

Switch on the ignition.

Shift the automatic transmission to
neutral positionN.

If engaged, manually release the
electronic parking brake.
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 brake
system


there is a malfunction in the power sup-
ply or in the vehicle’s electrical system
This is necessary to adequately control the
towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make certain the SmartKey is in
starter switch position2.
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.
!
Keep in mind that it is important to have the
ignition switched on. As soon as the SmartKey is
removed from the starter switch or the SmartKey
with KEYLESS-GO* is removed from the vehicle,
the automatic transmission will shift to park
positionP.
!
The vehicle may be towed only for distances
up to 30 miles (50 km) and at a speed not to ex-
ceed 30 mph (50 km/h).
i
To signal turns while being towed with the
hazard warning flasher in use, the ignition must
be switched on. You can then activate the com-
bination 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 hazard warn-
ing flasher will operate again.

715 Practical hintsFuses
Before replacing fuses:
Engage the electronic parking brake
(page 412).

Make sure the automatic transmission
is set to park positionP (
page 417).
The gear position indicator in the multi-
function display should be on park
positionP.

Turn off all electrical consumers.

Turn off the engine (
page 415).

Switch off the vehicle’s internal electri-
cal functions (
page 705).

736 Technical dataFuels, coolants, lubricants, etc.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
required for vehicles with Maintenance
System. For a listing of approved engine
oils and oil filters, refer to the Factory
Approved Service Products pamphlet (USA
only), or contact an authorized
Mercedes-Benz Center.
Engine oil additivesAir conditioning refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil are used in the air condition-
ing system.
Brake fluid
Only brake fluid approved by
Mercedes-Benz is recommended. Any au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.
!
Using engine oils and oil filters of
specification other than those expressly
required for the Maintenance System, or chang-
ing 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
damage not covered by the Mercedes-Benz Lim-
ited Warranty.
Please follow Maintenance System recommen-
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
Limited Warranty.
!
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.
!
Never use R-12 (CFC) or mineral-based
lubricating oil. Otherwise damage to the system
will occur.
Warning!
G
During vehicle operation, the boiling point of
the brake fluid is continuously reduced
through the absorption of moisture from the
atmosphere.
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 inter-
val.
