Tire pressure loss warning system
(Canada only)
General notes
While the vehicle is in motion, the tire pressure
loss warning system monitors the set tire pres-
sure using the rotational speed of the wheels.
This enables the system to detect significant
pressure loss in a tire. If the speed of rotation of
a wheel changes as a result of a loss of pressure,
a corresponding warning message will appear in
the multifunction display.
You can recognize the tire pressure loss warning
by the Run Flat Indicator Active
Press'OK' to Restartmessage which appears in
the Servicemenu of the multifunction display.
Information on the message display can be
found in the "Restarting the tire pressure loss
warning system" section (
Ypage 394).
Important safety notes
The tire pressure warning system does not warn you of an incorrectly set tire pressure. Observe
the notes on the recommended tire pressure
(
Ypage 387).
The tire pressure loss warning does not replace
the need to regularly check the tire pressure. An
even loss of pressure on several tires at the
same time cannot be detected by the tire pres-
sure loss warning system.
The tire pressure monitor is not able to warn you
of a sudden loss of pressure, e.g. if the tire is
penetrated by a foreign object. In the event of a
sudden loss of pressure, bring the vehicle to a
halt by braking carefully. Avoid abrupt steering
movements.
The function of the tire pressure loss warning
system is limited or delayed if:
Rsnow chains are mounted on your vehicle's
tires.
Rroad conditions are wintry.
Ryou are driving on sand or gravel.
Ryou adopt a very sporty driving style (corner-
ing at high speeds or driving with high rates of acceleration).
Ryou are driving with a heavy load (in the vehi-
cle or on the roof).

GVWR (Gross Vehicle Weight Rating)
The GVWR is the maximum permissible gross
weight of a fully loaded vehicle (the weight of thevehicle including all accessories, occupants,
fuel, luggage and the drawbar noseweight, if
applicable). The gross vehicle weight rating is
specified on the vehicle identification plate on
the B-pillar on the driver's side.
Maximum loaded vehicle weight
The maximum weight is the sum of:
Rthe curb weight of the vehicle
Rthe weight of the accessories
Rthe load limit
Rthe weight of the factory installed optional
equipment
Kilopascal (kPa)
Metric unit for tire pressure. 6.9 kPa corre-
sponds to 1 psi. Another unit for tire pressure is
bar. 100 kilopascals (kPa) are the equivalent of
1 bar.
Load index
In addition to the load-bearing index, the load
index may also be imprinted on the sidewall of
the tire. This specifies the load-bearing capacity
more precisely.
Curb weight
The weight of a vehicle with standard equipment
including the maximum capacity of fuel, oil and
coolant. It also includes the air-conditioning sys-
tem and optional equipment if these are instal-
led in the vehicle, but does not include passen-
gers or luggage.
Maximum load rating
The maximum tire load is the maximum permis-
sible 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 bydividing 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 out-
ward force to each square inch of the tire's sur-
face. The tire pressure is specified in pou
nds 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 tires are cold:
Rif the vehicle has been parked with the tires
out of direct sunlight 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 5 lbs (2.3 kg). These
optional extras, such as high-performance
brakes, level control, a roof rack or a high-per-
formance battery, are not included in the curb
weight and the weight of the accessories.
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 pur-
chasers. The TIN is made up of the manufactur- er's identity code, tire size, tire type code and
the manufacturing date.

Useful information
i
This Operator's Manual describes all models
and all standard and optional equipment of
your vehicle available at the time of publica-
tion of the Operator's Manual. Country-spe-
cific differences are possible. Please note
that your vehicle may not be equipped with all
features described. This also applies to
safety-related systems and functions.

workshops (Ypage 28).
Information regarding technical data

The data stated here specifically refers to a
vehicle with standard equipment. Consult an
authorized Mercedes-Benz Center for the
data for all vehicle variants and trim levels.
Vehicle electronics
Retrofitting two-way radios and
mobile phones (RF transmitters)
GWARNING
The electromagnetic radiation from modified
or incorrectly retrofitted RF-transmitters can
interfere with the vehicle electronics. This can compromise the operational safety of the
vehicle. There is a risk of an accident.
You should have all work to electrical and
electronic equipment carried out at a qualified
specialist workshop.
GWARNING
The electromagnetic radiation from incor-
rectly operated RF transmitters can interfere
with the vehicle electronics, for example:
Rif the RF transmitter is not connected with
an exterior antenna
Rthe exterior antenna has been installed
incorrectly or is not a low-reflection type
This can compromise the operational safety
of the vehicle. There is a risk of an accident.
Have the low-reflection exterior antenna
mounted at a qualified specialist workshop.
When operating RF transmitters in the vehi-
cle, always connect them with the low-reflec- tion exterior antenna.
!The operating permit may be invalidated if
the instructions for installation and use of RF
transmitters are not observed.
In particular, the following conditions must be complied with:
Ronly approved wavebands may be used.
Rcompliance with the maximum permissibleoutput in these wavebands is required.
Ronly approved antenna positions may be
used.
Excessive levels of electromagnetic radiation
may cause damage to your health and the health
of others. Using an exterior antenna takes into
account current scientific discussions relating
to the possible health hazards that may result
from electromagnetic fields.
Approved antenna positions (example:
Mercedes‑ Maybach)
:
Front roof area
;Rear roof area
=Rear fender
?Trunk lid
iOn vehicles with panorama roof with power
tilt/sliding panel, installing an antenna to the
front or rear roof area is not permitted.
On the rear fenders, it is recommended to
position the antenna on the side of the vehicle
closest to the center of the road.
Use the Technical Specification ISO/TS 21609
when retrofitting RF transmitters (Road Vehicles
