WARNING Risk of accident and injury
due to ov erloaded lines
If yo u man ipulate orbridg e afaulty fuse or if
yo ure place it with a fuse with a higher
amperage, the electric line could be overloa‐
ded.
This could result in a fire .
#Alw aysre place faulty fuses with speci‐
fi ed new fuses conta iningthe cor rect
amperage.
* NO
TEDama gecaused byincor rect fuses
Incor rect fuses may cause damage toelectri‐
cal components or sy stems.
#Only use Mercedes-Benz appr oved
fuses with the cor rect fuse rating.
Blown fuses must bereplaced with fuses of the
same rating, which you can recognize bythe
color and fuse rating. The fuse ratings are li sted in
the fuse assignment diagram. The fuse assign‐
ment diagram is in theve hicle document wallet.
* NO
TEDama geor malfunctions caused
by moisture
Moisture may cause dama getothe electrical
sy stem or cause it tomalfunction.
#When the fuse box is open, make sure
th at no moisture can enter the fuse
box.
#When closing the fuse box, make sure
th at the seal of the lid is positioned cor‐
re ctly on the fuse box.
Ifth e newly inser ted fuse also blo ws, ha vethe
cause traced and rectified at a qualified special‐
ist workshop, e.g. an authorized Mercedes-Benz
Center.
Ensure thefo llowing before replacing a fuse:
RThe vehicle is secured against rolling away.
RAll electrical consumers are switched off.
RThe ignition is switched off. The electrical fuses are located in
various fuse
bo xes:
RFu se box in the engine compartment on the
driver's side (→page 410)
RFu se box on the driver's side of the dash‐
board (→page 412)

The tire pressuretable sho ws there commended
tire pressure for all tires app rove dfo rth is vehi‐
cle. The recommended tire pressures apply for
cold tires under various operating conditions, i.e.
loading and/or speed of theve hicle.
If one or more tire sizes precede a tire pressure,
th e tire pressure information following is only
va lid forth ose tire sizes.
The load conditions "partially laden" and "fully
laden" are defined in theta ble for dif fere nt num‐
be rs of passengers and amounts of luggage. The
actual number of seats may dif fer from this.
Some tire pressure tables only show therim
diame ter ins tead of the comple tetire size, e.g.
R18 . The rim diame ter is part of the tire size and
can be found on the tire side wall (
→page 428).
Be sure toalso observ eth efo llowing fur ther
re lated subjects:
RNo tes on tire pressure (→page 414)
RTire and Loading Info rmation placard
(→page 420)
RMaximum tire pressure (→page 428)
Checking tire pressure s manually
#Read the tire pressure forth e cur rent operat‐
ing conditions from theTire and Loading
Info rmation placard or the tire pressure
ta ble. Obser vethe no tes on tire pressure.
#Re mo vetheva lve cap of the tire tobe
ch ecked.
#Press the tire pressure gauge securely onto
th eva lve.
#Re ad the tire pressure.
#Ifth e tire pressure is lo werth an there com‐
mended value, inc rease the tire pressure to
th ere commended value.
#Ifth e tire pressure is higher than there com‐
mended value, release air. Todo so, press
down the me tal pin in theva lve, e.g. using
th e tip of a pen forex ample. Then check the
tire pressure again usingthe tire pressure
ga uge.
#Sc rew theva lve cap onto theva lve.

these are ins talled on theve hicle, but does not
include passengers or luggage.
Maximum tire load: the maximum tire load is
th e maximum permissible weight in kilog rams or
lbs for which a tire is appr oved.
Maximum permissible tire pressure: maxi‐
mum permissible tire pressure for one tire.
Maximum load on one tire: maximum load on
one tire. This is calculated bydividing the maxi‐
mum axle load of one axle bytwo.
PSI (pounds per square in ch):standard unit of
measurement for tire pressure .
Aspect ratio: ratio between tire height and tire
width in pe rcent.
Ti re pressure: pressure inside the tire applying
an outward forc eto eve rysquare inch of the tire.
The tire pressure is specified in pounds per
square inch (psi), in kilopascals (kPa) or in bar.
The tire pressure should only be cor rected when
th e tires are cold.
Cold tire pressure: the tires are cold when the
ve hicle has been par kedfo r at least 3 hours without direct sunlight on
the tires or theve hicle
has been driven for less than 1 mile (1.6 km).
Ti re contact sur face: the part of the tire that
comes into con tact wi th thero ad.
Ti re bead: the purpose of the tire bead is to
ensure that the tire sits securely on the wheel
ri m. There are se veral wire cores in the tire bead
to pr
eve ntthe t
ire fromchanging length on the
wheel rim.
Side wall:the part of the tire between the tread
and the tire bead.
We ight of optional equipment: the combined
we ight of the optional equipment weighing more
th an there placed standard parts and more than
5 lbs (2.3 kg).This optional equipment, such as
high-per form ance brakes, le vel control sy stem, a
ro of luggage rack or high-per form ance batte ries,
is not included in the curb weight and thewe ight
of the accessories.
TIN (Tire Identification Number): a unique
identification number which can be used bya
tire manufactu rerto identify tires, forex ample,
in a product recall, and thus identify the pur‐
ch asers. The TIN is made up of the manufactur‐ er's identity code, tire size, tire type code and
th
e manufacturing date.
Load-bearing index: the load-bearing index is a
code that con tains the maximum load-bearing
capacity of a tire.
Tr action: traction is the grip resulting from fric‐
tion between the tires and thero ad sur face.
We ar indicator: narrow bars (tread wear bars)
th at are distributed overth e tire conta ct surface.
If th e tire tread is le vel with the bars, thewe ar
limit of 1/ 16in (1.6 mm) has been reached.
Distribution of vehicle occupants: distribution
of vehicle occupants ov
er design
ated seat posi‐
tions in a vehicle.
Maximum permissible pa yload weight: nomi‐
nal load and luggage load plus 150 lb (68 kg)
multiplied bythe number of seats in theve hicle.

WARNING Risk of injury orfata l injury when using a child restra int sy stem while the front passenger air bag
is enabled
If yo u secure a child in a child restra int sy stem on the front passenger seat and the front passenger air bag is
enabled, the front passenger air bag can deploy in theev ent of an accident.
The child could be stru ck bythe air bag.
#Ensure, bo thbefore and during the journe y,that thest atus of the front passenger air bag is cor rect.
NEVER use a rear wa rdfacing child restra int on a seat pr otected byan ACTIVE FRONT AIR BAG; DE ATH or SERI‐
OUS INJU RYtotheCH ILD can occur.
#Pull over and stop theve hicle safely as soon as possible, paying attention toroad and traf fic conditions.
#Check thest atus of the automatic front passenger air bag shutoff .
#If necessar y,consult a qualified specialist workshop immediatel y.
