Restarting Advanced TPMS
G
Warning!
It is the driver’s responsibility to set the tire
inflation pressure to the recommended cold
tire inflation pressure. Underinflated tires
affect
the ability to steer or brake the vehicle.
You might lose control over the vehicle.
When you restart the TPMS, the system sets
new reference values for each tire.
The TPMS must be restarted 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.
Restart the TPMS after adjusting the tire
inflation pressure to the inflation pressure
recommended for the vehicle operating
condition. Tire inflation pressure should only
be adjusted on cold tires. Observe the
recommended tire inflation pressure on the
Tire and Loading Information placard on the
driver’s door B-pillar. Some vehicles may have
supplemental tire inflation pressure
information for driving at high speeds or for
vehicle loads less than the maximum loaded
vehicle condition. If such information is
provided, it can be found on the inside of the
fuel filler flap.
Canada only:
The TPMS usually recognizes tire pressure
adjustments and sets new reference values
automatically. You can, however, restart the
TPMS manually as described.
X Using the Tire and Loading Information
placard on the driver’s door
B-pillar
(Y page 193) or the supplemental tire
inflation pressure information on the inside
of the fuel filler flap, make sure the tire
inflation pressure of all four tires is correct.
X Switch on the ignition.

multifunction steering wheel repeatedly
until the standard display appears in the
multifunction display

i When the wheel positions have been
changed, the inflation pressure of a tire

temporarily.
After driving for a few minutes,
the inflation pressure will be shown for the

Warning!
Never exceed the maximum tire inflation
pressure. Follow recommended tire inflation
pressures.

dimension front vs. rear), tire rotation is not
possible.
If applicable to your vehicle’s tire
configuration, tires can be rotated according
to the tire manufacturer’s recommended
intervals in the tire manufacturer’s warranty
pamphlet located in your vehicle literature
portfolio. If none is available, tires should be
rotated every 3 000 to 6
000 miles (5 000 to
10 000 km), or sooner if necessary, according
to the degree of tire wear. The same rotation
(spinning) direction must be maintained.
Rotate tires before the characteristic tire
wear pattern becomes visible (shoulder wear
on front tires and tread center wear on rear
tires).
Thoroughly clean the mounting face of wheels
and brake disks, i.e. the inner side of the
wheels/tires, during each rotation. Check for
and ensure proper tire inflation pressure.
For information on wheel change, see “Flat
tire” ( Y page 271). Tire labeling
Besides tire name (sales designation) and
manufacturer name, a number of markings
can be found on a tire.
Following are some explanations for the
markings on your vehicle’s tires: :

An automotive glass cleaner is
recommended.
! Fold the windshield wiper arms back onto
the windshield before turning the SmartKey
in the starter switch or pressing the
KEYLESS-GO start/stop button.
Hold on to the wiper when folding the wiper
arm back. If released, the force of the
impact from the tensioning spring could
crack the windshield.
! To clean the window interior, do not use
a dry cloth, abrasives, solvents or cleaners
containing solvents. Do not touch the
inside of the windows with hard objects
such as an ice scraper or ring. Doing so may
damage the windows.
Light alloy wheels If possible, clean wheels once a week.
X
Use Mercedes-Benz approved Wheel Care,
a soft bristle brush and a strong spray of
water for cleaning the light alloy wheels.
! Only use acid-free cleaning materials.
Acid may cause corrosion or damage the
clear coat.
! The vehicle should not be parked for an
extended period of time immediately after
it
has been cleaned. This applies especially
after the wheel rims have been cleaned
with wheel rim cleaner. Wheel rim cleaners
can lead to increased corrosion of the
brake disks and brake pads. Non-approved
wheel cleaners may also damage the wheel
paint if the vehicle is not driven after
cleaning.
Therefore, the vehicle’s brake system
should always be warmed-up before it is
parked after cleaning. Drive your vehicle for
several minutes to allow the brakes to dry.
When applying Mercedes-Benz approved
Tire Care and Mercedes-Benz approved
Wheel Care products, take care not to
spray them on the brake disks. Plastic and rubber parts X
Use a gentle dishwashing detergent or mild
detergent
for delicate fabrics as a washing
solution.
X Wipe with a cloth moistened in a lukewarm
solution.
The
surface may temporarily change color.
If this is the case, wait for it to dry. G
Warning!
Do not use cleaners or cockpit care sprays
containing
solvents to clean the cockpit or the
steering wheel. Cleaners containing solvents
will make the surface porous and vehicle
occupants could suffer serious injuries from
plastic parts coming loose in the event of air
bag deployment.
! Do not use oil, wax or scouring agents.
Otherwise you may scratch or damage the
surface.
Hard plastic trim items
X Use Mercedes-Benz approved Interior Care
on
a soft, lint-free cloth and apply with light
pressure.
COMAND display !
You
must switch off the COMAND display
and allow it to cool prior to cleaning.
! Do not use any liquids or cleaning agents.
These can damage or even destroy the
COMAND display screen.
X Use a standard microfiber cloth and apply
with light pressure.
Steering wheel and gear selector lever X
Wipe with a damp cloth and dry thoroughly
or clean with Mercedes-Benz approved

Warning!
Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may
lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up
and possibly a fire. G
Warning!
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect
handling and fuel economy, and are more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear
unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are
more likely to become punctured or damaged by road debris, potholes etc. Symbol messages
