Electrical fuses
Notes on electrical fuses
&WARNING Risk of accident and injury due
to overloaded lines
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher amper-
age, the electric line could be overloaded.
This could result in a Nre.Always replace faulty fuses with speci-
Ned new fuses containing the correct
amperage.*NOTE Damage due to incorrect fuses
Using incorrect fuses can result in damage to
electrical components or systems or their functions being considerably restricted.
Use only fuses approved for Mercedes-
Benz with the respective speciNed fuse
rating.
Blown fuses must be replaced with fuses of the
same rating, which you can recognize by the color and the label. The fuse ratings and further infor-
mation to be observed can be found in the fuse
assignment diagram.
Fuse assignment diagram: on the fuse box in the
rear passenger compartment (  page 401).
*NOTE Damage or malfunctions caused by
moisture
Moisture may cause damage to the electrical
system or cause it to malfunction.
When the fuse box is open, make sure
that no moisture can enter the fuse box.When closing the fuse box, make sure
that the seal of the lid is positioned cor-
rectly on the fuse box.
If the newly inserted fuse also blows, have the cause traced and rectiNed at a qualiNed specialist
workshop.
Ensure the following before replacing a fuse: = The vehicle is secured against rolling away.

Notes on noise or unusual handling characteris-tics
Make sure there are no vibrations, noises or unusual handling characteristics when the vehicle
is in motion. This may indicate that the wheels or
tires are damaged. Hidden tire damage could also
be causing the unusual handling characteristics.
If you suspect that a tire is defective, reduce yourspeed immediately and have the tires and wheels
checked at a qualiNed specialist workshop.
Notes on regularly inspecting wheels and tires
&WARNING Risk of injury through damaged
tires
Damaged tires can cause tire pressure loss.
Check the tires regularly for signs of
damage and replace any damaged tires immediately.&WARNING Risk of hydroplaning due to
insuPcient tire tread
*nsuPcient tire tread will result in reduced tire
grip.
In heavy rain or slush the risk of hydroplaning is increased, in particular where speed is not
adapted to suit the conditions.
Thus, you should regularly check the
tread depth and the condition of the
tread across the entire width of all tires.
Minimum tread depth for:
= Summer tires:

Notes on snow chains&WARNING Risk of accident due to incor-
rectly installed snow chains
If you have installed snow chains on the front wheels, they may drag against the vehicle
body or chassis components.
Never install snow chains on the front
wheels.Only install snow chains on the rear
wheels in pairs.*NOTE Damage to components of the vehi-
cle body or chassis due to mounted snow
chains
If you mount snow chains to the front wheels
of 4MATIC vehicles, you may damage compo-
nents of the vehicle body or chassis.
Only mount snow chains to the rear
wheels of 4MATIC vehicles.*NOTE Damage to wheel trims due to snow
chains being installed
If you install snow chains on aluminum wheels
you could damage the wheel trims.
Remove the wheel trims from the alumi-
num wheels before installing snow
chains.
Observe the following notes when using snow
chains:
= Snow chains are only permissible for certain
wheel/tire combinations. You can obtain infor-
mation about this from an authorized
Mercedes-Benz Service Center.
= For safety reasons, only use snow chains that
have been speciNcally approved for your vehi-
cle by Mercedes-Benz, or snow chains with the same quality standard.
= Comply with the installation instructions of the
snow chain manufacturer.
= If snow chains are installed, the maximum per-
missible speed is 30 mph (50 km/h).
= Vehicles with Active Parking Assist: do not use
Active Parking Assist when snow chains are
installed.
= Vehicles with rear axle steering: if snow chains
are installed, only drive with snow chain mode
active (  page 403).\bYou can deactivate ESP n
to pull away
(  page 232). This allows the wheels to spin,
achieving an increased driving force.
Activating or deactivating snow chain mode

Z
Activate or deactivate Snow Chain Mode.
When the function is active, the vehicle behaves
as if snow chains were installed. For example, the
maximum steering movement of the rear wheels
is limited and the turning circle is thus increased.
Additionally, parts of the driving and driving safety
systems are not available when snow chain mode
is active.

Tire pressure
Notes on tire pressure
&WARNING Risk of accident due to insuP-
cient or excessive tire pressure
UnderinOated or overinOated tires pose in par-
ticular the following risks:
= The tires can burst.
= The tires can wear excessively and/or
unevenly.
= The driving characteristics as well as the
steering and braking characteristics may
be greatly impaired.
Comply with the recommended tire pres-
sures and check the tire pressure of all
tires, including the spare wheel, regu-
larly:
= Monthly
= When the load changes
= Before embarking on a longer journey
=
If operating conditions change, e.g. oM-
road drivingAdjust the tire pressure, if necessary.
Tire pressure which is too high or too low can:
= Shorten the service life of the tires.
= Cause increased tire damage.
= Adversely aMect driving characteristics and
thus driving safety, e.g. due to hydroplaning.
&WARNING Risk of accident due to too low
a tire pressure
Tires with pressure that is too low can over-
heat and burst as a consequence.
In addition, they also suMer from irregular
wear, which can signiNcantly impair the brak-
ing properties and the handling characteris-
tics.
Avoid excessively low tire pressure.
Tire pressure which is too low can cause:
= Tire defects as a result of overheating
=Impaired handling characteristics
= Irregular wear
= Increased energy consumption&WARNING Risk of accident due to too high
a tire pressure
Tires with excessively high pressure can burst.
In addition, they also suMer from irregular
wear, which can signiNcantly impair the brak-
ing properties and the handling characteris-
tics.
Avoid excessively high tire pressures.
Tire pressure which is too high can cause:
= Increased braking distance
= Impaired handling characteristics
= Irregular wear
= Impaired driving comfort
= Susceptibility to damage
404Wheels and tires

&WARNING Risk of accident due to repea-
ted pressure drop in the tires
The wheels, valves or tires could be damaged.
Too low a tire pressure can lead to the tires
bursting.
Examine the tires for foreign objects.Check whether the tire has a puncture or
the valve has a leak.If you are unable to rectify the damage,
contact a qualiNed specialist workshop.
You can Nnd information on tire pressure for the
vehicle\bs factory-installed tires on the following
labels on the B-pillar on the driver\bs side:
= Tire and Loading Information placard
(  page 409)
= Tire pressure table (  page 405).
Observe the maximum tire pressure
(  page 415).
Use a suitable pressure gage to check the tire
pressure. The outer appearance of a tire does not
permit any reliable conclusion about the tire pres-
sure.
Only correct tire pressure when the tires are cold.
Conditions for cold tires:
= The vehicle has been parked with the tires out
of direct sunlight for at least three hours.
= The vehicle has traveled less than 1 mile
(1.6 km).
The vehicle\bs tires heat up when driving. As the temperature of the tires increases, so too doesthe tire pressure.
Vehicles with a tire pressure monitoring system: you can also see the tire pressure in the driver\bs
display (  page 408).
The tire pressure recommended for increased
load/speed in the tire pressure table can aMect
the ride comfort.&WARNING Risk of accident due to unsuita-
ble accessories on tire valves
If you mount unsuitable accessories onto tire
valves, the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss.Only screw standard valve caps or valve
caps speciNcally approved by Mercedes-
Benz for your vehicle onto the tire valve.
Tire pressure table
The tire pressure table is on the B-pillar on the driver\bs side.
\bThe data shown in the images is example
data.Wheels and tires405

The tire pressure table shows the recommended
tire pressure for all tires approved for this vehicle.
The recommended tire pressures apply for cold
tires under various operating conditions, i.e. load-
ing and/or speed of the vehicle.
If one or more tire sizes precede a tire pressure,
the tire pressure information following is only valid for those tire sizes.
The load conditions "partially laden" and "fully
laden" are deNned in the table for diMerent num-
bers of passengers and amounts of luggage. The actual number of seats may diMer from this.
Some tire pressure tables only show the rim diam-
eter instead of the complete tire size, e.g. R18.
The rim diameter is part of the tire size and can
be found on the tire side wall (  page 416).
Be sure to also observe the following further rela-
ted subjects:

Checking the tire pressure manually
Read the tire pressure recommended for the
current operating conditions from the tire and
loading information placard or the tire pres-
sure table. Observe the notes on tire pressure.Remove the valve cap of the tire to be
checked.Press the tire pressure gauge securely onto the valve.Read the tire pressure.If the tire pressure is lower than the recom-
mended value, increase the tire pressure to
the recommended value.If the tire pressure is higher than the recom- mended value, release air. To do so, press
down the metal pin in the valve, e.g. using the
tip of a pen. Then check the tire pressure
again using the tire pressure gauge.Screw the valve cap onto the valve.406Wheels and tires

Tire pressure monitoring system

qFunction of the tire pressure monitor
&DANGER Risk of accident due to incorrect
tire pressure
Each tire, including the spare (if provided),
should be checked monthly when cold and inOated to the inOation pressure recommen-
ded by the vehicle manufacturer on the vehi- cle placard or tire inOation pressure label. (If
your vehicle has tires of a diMerent size than
the size indicated on the vehicle placard or
tire inOation pressure label, you should deter-
mine the proper tire inOation pressure for
those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pres-sure telltale when one or more of your tires is
signiNcantly under-inOated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inOate them to the proper pres-
sure. Driving on a signiNcantly under-inOated
tire causes the tire to overheat and can lead
to tire failure. Under-inOation also reduces fuel
ePciency and tire tread life, and may aMect
the vehicle!

The tire pressure monitor is only an aid. It is thedriver\bs responsibility to set the tire pressure to
the recommended cold tire pressure suitable for
the operating situation.
In most cases, the tire pressure monitor will auto-
matically update the new reference values aser
you have changed the tire pressure. You can, however, also update the reference values byrestarting the tire pressure monitor manually
(  page 408).
System limits
The system may be impaired or may not function particularly in the following situations:
= Incorrect reference values were taught in
= Sudden pressure loss caused by a foreign
object penetrating the tire, for example
= Malfunction caused by another radio signal
source

q Checking the tire pressure with the tire pres-
sure monitoring system
Requirements
= The vehicle is switched on.Driver\bs display:

ServicePress v to conNrm.
One of the following displays appears:
= Current tire pressure of each wheel:
=Tire pressure displayed after driving for a
few minutes. : current values are not yet
known to the system. The pressure/tempera-
ture values of each tire are displayed as soon
as they are known to the system.
= Tire Pressure Monitor Active : the teach-in
process of the system is not yet complete. The
tire pressures are already being monitored.
Compare the current tire pressure with the
recommended tire pressure for the current
operating condition (  page 405). Addition-
ally, observe the notes on cold tires (  page 404).\bThe values displayed in the driver\bs display
may deviate from those of the tire pressure
gauge as they refer to sea level. At high eleva-
tions, the tire pressure value indicated by a
tire pressure gauge is higher than that shown
in the driver\bs display.
Bear in mind the following related topic:
= Notes on tire pressure (  page 404)

q Restarting the tire pressure monitoring system
Requirements
= The recommended tire pressure is correctly
set for the respective operating status on each
of the four wheels (  page 404).
Restart the tire pressure monitoring system in the following situations:
= The tire pressure has changed.
