Open trim at the trim strips in the roof.

Secure the roof rack according to man-
ufacturer’s instructions for installation.
Loading instructions
The total load weight including vehicle oc-
cupants and luggage/cargo should not ex-
ceed the vehicle capacity weight indicated
on the certification tag which can be found
on the left door pillar.
Warning!
G
Use only roof racks approved by
Mercedes-Benz for your vehicle model to
avoid damage to the vehicle. Follow manu-
facturer’s installation instructions.
!Load the roof rack in such a way that
the vehicle cannot be damaged while
driving.
Make sure that

you can fully raise the sliding /
pop-up roof


you can fully open the trunk

248OperationTires and wheelsTire pressure changes by approximately
1.5 psi (0.1 bar) per 18°F (10°C) of air
temperature change. Keep this in mind
when checking tire pressure where the
temperature is different from the outside
temperature.
Tire temperature and tire pressure also in-
crease while driving, depending on the
driving speed and the tire load.Check the spare tire periodically for condi-
tion and inflation pressure. Spare tires will
age and become worn over time even if
never used, and thus should be inspected
and replaced when necessary or after a
maximum of six years.Checking tire pressure electronically*
The tire inflation pressure monitor only
functions on wheels that are equipped with
the proper electronic sensors. It monitors
the tire inflation pressure, as selected by
the driver, in all four tires. A warning is is-
sued to alert you to a decrease in pressure
in one or more of the tires.
Tire pressure inquiries are made using the
multifunction display (
page 117). The in-
flation pressures are displayed only after a
few minutes’ travel time.
You can select the unit of measure used for
the tire inflation pressure by changing the
setting in the control system (
page 117).
iThe pressures listed for light loads are
minimum values offering high driving
comfort.
Increased inflation pressures listed for
heavier loads may also be used for light
loads. These higher pressures produce
favorable handling characteristics. The
ride of the vehicle, however, will be
somewhat harder. Never exceed the
max. values or inflate tires below the
min. values listed on the fuel filler flap.
Warning!
G
Follow recommended inflation pressures.
Do not overinflate tires. Overinflated tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the pillar in the driver’s
door opening). Overloading the tires can
overheat them, possibly causing a blowout.
iPossible differences between the read-
ings of a tire pressure gauge of an air
hose, e.g. gas station equipment, and
the vehicle’s control system can occur.
The readings issued by the control sys-
tem are more precise.

249 Operation
Tires and wheels

Switch on the ignition.

Press button
è
or
ÿ
on the mul-
tifunction steering wheel repeatedly
until the standard display menu ap-
pears in the multifunction display
(
page 118).

Press the
k
or
j
button repeat-
edly until you see the current inflation
pressures for each tire appear in the
display.
Warning!
G
The tire inflation pressure monitor does not
indicate a warning for wrongly selected in-
flation pressures. Always adjust tire inflation
pressure according to the label affixed on
the fuel filler flap.
The tire inflation pressure monitor is not
able to issue a warning due to a sudden loss
of pressure (e.g. tire puncture caused by a
foreign object). In this case bring the vehicle
to a halt by carefully applying the brakes and
avoiding abrupt steering maneuvers.

Do not overinflate tires. Overinflated tires
can result in a sudden deflation (blowout)
because they are more likely to become

ment (e.g. wireless headsets, two-way
radios) in or near the vehicle could
cause the tire inflation pressure moni-
tor to malfunction.
