Information on 4MATIC vehicles
!
Vehicles with 4MATIC must not be towed
wit h either the front or the rear axle raised,
as doin g so willdamage the transmission.
If the vehicle has transmission damage or
damage to the front or rear axle, have it trans- ported on a transporter or trailer.
In the event ofdamage tothe electri cal
system
If the battery isdefective, the automat ic
transmission will belocked in position P. To
shift the automat ictransmission to position
N , you must pro videpower to the vehicle's
electrical system in the same way as when
jum p-starting (
Ypage 395).
Have the vehicle transported on a transporter
or trailer.
Tow-starting (emergency engine
starting)
!
Vehicles with automat ictransmission
must not betow-starte d.You could other-
wise damage the automat ictransmission.

Important safety notes
GWARNIN G
If you manipulat eor bridge afault yfus eor if
you replace it wit h afusewit h a higher amper-
age, th eelectric cables could be overloaded.
This could result in afire. Ther eis aris kof an
acciden tand injury.
Always replace fault yfuses wit hth especifie d
ne wfuses having th ecorrec tamperage .
!For the fuse boxes inthe engine compart-
ment and under the rear bench seat, only
use fuses with the suffix "S".Otherwise,
components or systems could be dam-
aged. The fuses
inyour vehicle serve to close down
faulty circuits. Ifa fuse blows, all the compo-
nents on the circuit and their functions stop
operating.
Blo wn fuses must bereplaced with fuses of
the same rating, which you can recogniz eby
the color and value. The fuse ratings are listed
in the fuse allocation chart.
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. an authorized
Mercedes-Benz Center.
Before changing a fuse
Observe the important safety notes
(
Ypage 400)
XSe cure the vehicle against rol ling away
(
Ypage 189).
XSwi tch off the engine.
XSwitch off all electrical consumers.
XRemo vethe SmartKey from the ignit ion
lock.
or, on vehicles with KEYLESS‑ GO:
XOpen the driver's door.
The on-board electronics now have status
0. Thisisthe same as the SmartKey having
been remove d.
All indicator lamps inthe instrument cluster
must beoff.
The fuses are located invarious fuse boxes:
RFuse box on the front-passenger side of the
dashboard
RFuse box inthe engine compartment on the
right-hand side of the vehicle, when viewed
in the direction of travel
RFuse box under the rear bench seat
The fuse allocation chart islocated inthe fuse
box under the rear bench seat (

Breakdown assistance
the tire. This specifies the load-bearing capa-
city more precisely.
Curb weight
The weight of a vehicle with standard equip-
ment including the maximum capacity of fuel,
oil and coolant. It also includes the air-condi-
tioning system and optional equipment if
these are installed in the vehicle, but does not
include passengers or luggage.
Maximum load rating
The maximum load rating is the maximum
permissible weight in kilograms or lbs for
which a tire is approved.
Maximum permissible tire pressure
Maximum permissible tire pressure for one
tire.
Maximum load on one tire
Maximum load on one tire. This is calculated
by dividing the maximum axle load of one axle
by two.
PSI (pounds per square inch)
A standard unit of measure for tire pressure.
Aspect ratio
Relationship between tire height and tire
width in percent.
Tire pressure
This is pressure inside the tire applying an
outward force to each square inch of the tire's surface. The tire pressure is specified in
pounds per square inch (psi), in kilopascal
(kPa) or in bar. The tire pressure should only
be corrected when the tires are cold.
Cold tire pressure
The ti
res are cold:
Rif the vehicle has been parked without
direct sunlight on the tires for at least three
hours and
Rif the vehicle has not been driven further
than 1 mile (1.6 km) Tread
The part of the tire that comes into contact
with the road.
Bead
The tire bead ensures that the tire sits
securely on the wheel. There are several steel
wires in the bead to prevent the tire from
coming loose from the wheel rim.
Sidewall
The part of the tire between the tread and the
bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 2.3 kg (5 lbs). These
optional extras, such as high-performance
brakes, level control, a roof rack or a high-
performance battery, are not included in the
curb weight and the weight of the accesso-
ries.
TIN (Tire Identification Number)
This is a unique identifier which can be used
by a tire manufacturer to identify tires, for
example for a product recall, and thus identify
the purchasers. The TIN is made up of the
manufacturer's identity code, tire size, tire
type code and the manufactu ring d
ate.
Load bearing index
The load bearing index (also load index) is a
code that contains the maximum load bearing
capacity of a tire.
Traction
Traction is the result of friction between the
tires and the road surface.
TWR (Tongue Weight Rating)
The TWR specifies the maximum permissible
weight that the ball coupling of the trailer tow hitch can support.
