reached, the following message appears in
the multifunction display for five seconds:
Indicator lamp2 (
page 252) goes out.The following applies additionally when
towing a trailer:


The vehicle is lowered to the highway
level when it reaches a speed of 5 mph
(8 km/h).


The high-speed level is not available.


The restrictions that apply to towing
also apply when using accessories that
are connected to the trailer power
socket, such as an accessory bicycle
rack.
Parktronic* system (Parking assist)
iThe vehicle is lowered to the highway
level if:

the vehicle speed is above 55 mph
(88 km/h)


the speed stays between 40 mph
(64km/h) and 55mph (88km/h)
for approximately 20 seconds
iDepending on the ADS setting
(page 249), the vehicle will be low-
ered to the high-speed level when trav-
eling at higher speeds. At speeds below
40 mph (64 km/h) at the latest, it will
be returned to the highway level.
Warning!
G
Parktronic is a supplemental system. It is
not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always rests with the driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or road
curbs). Such objects may not be detected by
the system and can damage the vehicle.
The operational function of the Parktronic
system can be affected by dirty sensors, es-
pecially at times of snow and ice. See
“Cleaning the Parktronic system sensors”
(page 377).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers, car wash,
or the air brakes of trucks) can cause the
system to send erratic indications, and
should be taken into consideration.


348 OperationTires and wheels
Install the valve cap.

Repeat this procedure for each tire.Run Flat Indicator
While the vehicle is being driven, the Run
Flat Indicator monitors the set tire inflation
pressures by evaluating each wheel’s rota-
tional speed. This allows the system to de-
tect a significant loss of pressure in a tire.
If a wheel’s rotational speed changes due
to falling tire inflation pressure, you will
see a corresponding warning message in
the multifunction display.
The Run Flat Indicator may function in a re-
stricted manner or with a delay if:


snow chains are mounted to the
vehicle


winter road conditions prevail


you are driving on a loose surface (e.g.
sand or gravel)


you are driving in a very sporty manner
(involving rapid acceleration or high
speeds in curves)
iIf you have overfilled the tire, release
tire inflation pressure by pushing the
metal stem of the valve with e.g. a tip of
a pen. Then recheck the tire inflation
pressure with the tire gauge.
Warning!
G
When the multifunction display shows the
message
Tire pressure Check tires
,
one or more of your tires is significantly un-
der-inflated. You should stop and check
your tires as soon as possible, and inflate
them to the proper tire inflation pressure as
indicated on the vehicle’s tire information
placard. Driving on a significantly under-in-
flated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability. Each tire, including the
spare, should be checked monthly when
cold and set to the recommended tire infla-
tion pressure as specified in the vehicle
placard and owner’s manual.


353 Operation
Tires and wheels
Reactivating Advanced TPMS*
The TPMS must be reactivated when you
have adjusted the tire inflation pressure to
a new level (e.g. because of different load
or driving conditions). The TPMS is then
recalibrated to the current tire inflation
pressures.
Using the tire placard on the driver’s
door B-pillar (
page 339) or, if avail-
able, the supplemental tire pressure
information on the inside of the fuel fill-
er flap (
page 346), make sure the tire
inflation pressure of all four tires is cor-
rect.

Press buttonè orÿ on the mul-
tifunction steering wheel repeatedly
until the standard display menu ap-
pears in the multifunction display
(page 156).
iIf a condition causing the TPMS to mal-
function develops, it may take up to
10 minutes for the system to signal a
malfunction using the TPMS telltale
flashing and illumination sequence.
The telltale extinguishes after a few
minutes driving if the malfunction has
been corrected.iOperating radio transmission equip-
ment (e.g. wireless headsets, two-way
radios) in or near the vehicle could
cause the TPMS to malfunction.
iReactivate the TPMS after adjusting
the tire inflation pressure to the infla-
tion pressure recommended for the
vehicle operating condition. Tire pres-
sure should only be adjusted on cold
tires. Observe the recommended tire
inflation pressure on the placard on the
driver’s door B-pillar (
page 339).
Some vehicles may have supplemental
tire pressure information for driving at
high speeds (
page 346) or for vehicle
loads less than the maximum loaded
vehicle condition (
page 346). If such
information is provided, it can be found
on the inside of the fuel filler flap.


371 Operation
Maintenance
Maintenance
We strongly recommend that you have
your vehicle serviced by an authorized
Mercedes-Benz Light Truck Center, in
accordance with the Maintenance Booklet
at the times called for by the maintenance
service indicator display.
Failure to have the vehicle maintained in
accordance with the Maintenance Booklet
and maintenance service indicator at the
designated times/mileage will result in
vehicle damage not covered by the
Mercedes-Benz Limited Warranty.
The maintenance service indicator will no-
tify you when your next maintenance ser-
vice is due.
Starting approximately one month before
maintenance service is due, one of the fol-
lowing messages will appear in the multi-
function display while you are driving or
when you switch on the ignition (example
service A):
Service A in XXXXX miles (km)
Service A in XXX days
Service A in X dayThe maintenance services will be indicated
by showing a service type A through type H
in the multifunction display. Types A
through H are classified based on estimat-
ed time needed to perform the mainte-
nance service, ranging:
from
Service A(approx. one hour)
toService H(approx. eight hours)
iVehicles equipped with FSS PLUS
(Flexible S
ervice S
ystem PLUS) only
(Canada vehicles): The interval be-
tween maintenance services depends
on your driving habits. A gentle driving
style, moderate engine speeds and the
avoidance of short-distance trips will
lengthen the interval between services.
