Towing with all wheels on the ground
G
Warning!
If circumstances require towing the vehicle
with all wheels on the ground, always tow with
a tow bar if:
R the engine will not run
R there is a malfunction in the brake system
R there is a malfunction in the power supply
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 sure the SmartKey is in
starter switch position 2.G
Warning!
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
vehicle. Adapt your driving accordingly.
X Make sure the ignition is switched on.
X With the vehicle at a standstill, depress the
brake pedal and keep it pressed.
X Shift the automatic transmission into
neutral position N.
X Release the brake pedal.
X If engaged, release the parking brake.
X Switch on the hazard warning flasher
(Y page 101).
! Keep in mind that it is important to have
the ignition switched on. Removing the
SmartKey from the starter switch or
opening a front door with the ignition
switched off will automatically shift the
automatic transmission into park position
P.
! The vehicle may be towed only for
distances up to 30 miles (50 km) and at a
speed not to exceed 30 mph (50 km/h). i
While being towed with the hazard
warning

flasher in use, use the combination
switch in the usual manner to signal turns.
Only the selected turn signal will operate.
Upon canceling the turn signal, the hazard
warning flasher will operate again. Stranded vehicle
Freeing a stranded vehicle, on which the
wheels are dug into sand or mud, should be
done with the greatest of care, especially if
the vehicle is heavily loaded.
Note the following when freeing a stranded
vehicle:
R Avoid pulling the vehicle abruptly or
diagonally, since it could result in damage
to the chassis alignment.
R Never try to free a vehicle that is still
coupled to a trailer.
R If

possible, a vehicle equipped with a trailer
hitch receiver should be pulled backward in
its own previously made tracks. Fuses
Introduction
The electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and
systems secured by that fuse will stop
operating. G
Warning!
Only use fuses approved by Mercedes-Benz
with
the specified amperage for the system in
question and do not attempt to repair or
bridge a blown fuse. Using other than
approved fuses or using repaired or bridged
fuses may cause an overload leading to a fire,
and/or cause damage to electrical
components and/or systems. Have the cause
determined and remedied by an authorized
Mercedes-Benz Center. 340

! Using engine oils and oil filters of a
specification other than those expressly
required for the Maintenance System, or
changing 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 Limited
Warranty.
Please follow Maintenance System
recommendations for scheduled oil
changes. Failure to do so will result in
engine or emission control system damage
not covered by the Mercedes-Benz Limited
Warranty.

engine)
G
Warning!
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
personal injury.
Never allow sparks, flames or smoking
materials near gasoline!
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and any skin or clothing
contact. Extinguish all smoking materials.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging your
health.
! To maintain the engine’s durability and
performance, premium unleaded gasoline
must be used.
If premium unleaded gasoline is not
available and low octane gasoline is used,
follow these precautions:
R Have the fuel tank only partially filled
with

unleaded regular gasoline and fill up
with premium unleaded gasoline as soon
as possible.
R Avoid full throttle driving and abrupt
acceleration.
R Do not exceed an engine speed of
3 000 rpm if the vehicle is loaded with a light load such as two persons and no
luggage.
R Do not exceed 2
/ 3 of maximum
accelerator pedal position if the vehicle
is fully loaded or operating in
mountainous terrain. Fuel requirements
Gasoline engine Only use premium unleaded gasoline. The
octane

number (posted at the pump) must be
91 min. It is an average of both the Research
Octane Number (RON) and the Motor Octane
Number (MON): (RON+MON)/2. This is also
known as the ANTI-KNOCK INDEX.
Reformulated gasolines (RFG) and/or
unleaded gasoline containing oxygenates
such as ethanol, TAME, ETBE, IPA, IBA, and
TBA can be used provided the ratio of any one
of these oxygenates to gasoline does not
exceed 10%; MTBE must not exceed 15%.
The ratio of methanol to gasoline must not
exceed 3% plus additional cosolvents.
Using mixtures of ethanol and methanol is not
allowed. Gasohol, which contains 10%
ethanol and 90% unleaded gasoline, can be
used.
These blends must also meet all other fuel
requirements, such as resistance to spark
knock, boiling range, vapor pressure, etc.
