Plastic and rubber parts
Use a gentle dishwashing detergent or

warm solution.Hard plastic trim items
Use Mercedes-Benz approved Interior
Care, a soft, lint-free cloth and apply
with light pressure.
Steering wheel and gear selector lever
Wipe with a damp cloth and dry thor-
oughly or clean with Mercedes-Benz
approved Leather Care.
Carpets
Use Mercedes-Benz approved Carpet
and Fabric Care for cleaning the car-
pets.
!The vehicle should not be parked for an
extended period of time immediately
after it has been cleaned, especially not
after the wheel rims have been cleaned
with wheel rim cleaner. Wheel rim
cleaners can lead to increased corro-
sion of the brake disks and brake pads.
Therefore, the vehicle’s brake system
should always be warmed-up before it
is parked after cleaning.
When applying Mercedes-Benz ap-
proved Tire Care and Mercedes-Benz
approved Wheel Care products, take
care not to spray them on the brake
discs.
!Do not use oil or wax on these parts.!To prevent scratches, do not use scour-
ing agents.

H
Combination low tire
pressure/TPMS malfunction tell-
tale for the Advanced TPMS* illu-
minates continuously.
The Advanced TPMS* detects a loss of pres-
sure in at least one tire.
Carefully bring the vehicle to a halt,
avoiding abrupt steering and braking
maneuvers. Observe the traffic situa-
tion around you.
Read and observe messages in the
multifunction display.
If the tire inflation pressure in the respec-
tive tire(s) has (have) been corrected, the
combination low tire pressure/TPMS
malfunction telltale goes out after few
minutes driving.

Combination low tire
pressure/TPMS malfunction tell-

flashes for 60 seconds and then
stays illuminated.
There is a malfunction in the Advanced
TPMS*.
Read and observe messages in the
multifunction display.
Have the Advanced TPMS* checked
by an authorized Mercedes-Benz Cen-
ter.
After the malfunction has been remedied
the combination low tire pressure/TPMS
malfunction telltale goes out after few

Warning!
G
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or the tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or the tire inflation pressure label,
you should determine the proper tire infla-
tion pressure for those tires).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significant-
ly under-inflated tire causes the tire to over-
heat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping ability. Please
note that the TPMS is not a substitute for
proper tire maintenance, and it is the driv-
er’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately
one minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the mal-
function indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a variety
of reasons, including the installation of in-
compatible replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your vehicle
to ensure that the replacement or alternate
tires and wheels allow the TPMS to continue
to function properly.
