Important safety notes
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If you operate mobile communication equip-
ment when driving, you may be distracted
from the traffic situation. You could also lose
control of the vehicle. There is a risk of an
accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements for the countryin which you are driving. Some jurisdictions pro-hibit the driver from using a mobile phone whiledriving a vehicle.
If you make a call while driving, always usehands-free mode. Only operate the telephonewhen the traffic situation permits. If you areunsure, pull over to a safe location and stopbefore operating the telephone.

Notes on 4MATIC vehicles
!Vehicles with 4MATIC must not be towedwith either the front or the rear axle raised, asdoing so will damage the transmission.
Vehicles with 4MATIC may either be towed awaywith both axles on the ground or be loaded upand transported.
If the vehicle's transmission, front, or rear axle isdamaged, have the vehicle transported on atruck or trailer.
In the event of damage to the electrical sys-tem:if the battery is defective, the automatictransmission will be locked in positionP. To shiftthe automatic transmission to positionN, youmust provide power to the vehicle's electricalsystem in the same way as when jump-starting(Ypage 322).
Have the vehicle transported on a transporter ortrailer.
Tow-starting (emergency engine
starting)
!Vehicles with automatic transmission mustnot be tow-started. You could otherwise dam-age the automatic transmission.
iYou can find information on "Jump-starting"under (Ypage 322).
Fuses
Important safety notes
GWARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher amper-
age, the electric cables could be overloaded.
This could result in a fire. There is a risk of an
accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
Blown fuses must be replaced with fuses of thesame rating, which you can recognize by thecolor and value. The fuse ratings are listed in thefuse allocation chart.
The fuse allocation chart is on the fuse box in thecargo compartment (Ypage 328).
If a newly inserted fuse also blows, have thecause traced and rectified at a qualified special-ist workshop, e.g. an authorized Mercedes-BenzCenter.
!Only use fuses that have been approved forMercedes-Benz vehicles and which have thecorrect fuse rating for the system concerned.Otherwise, components or systems could bedamaged.
!Make sure that no moisture can enter thefuse box when the cover is open.
!When closing the cover, make sure that it islying correctly on the fuse box. Moisture seep-ing in or dirt could otherwise impair the oper-ation of the fuses.
The fuses in your vehicle serve to close downfaulty circuits. If a fuse blows, all the compo-nents on the circuit and their functions stopoperating.
Before changing a fuse
