stalled.Have the wheel sensors installed by an authorized
Mercedes-Benz Center.
As soon as all wheels with sensors have been mounted, the
Advanced TPMS is switched back on after driving for several
minutes.
Tire pressure monitor
currently unavailableThe Advanced TPMS is unable to monitor
the tire inflation pressure due to:

a nearby radio interference source

the on-board voltage is too low

excessive wheel sensor temperatures
As soon as the causes for the malfunction are no longer present,
the Advanced TPMS automatically becomes active again after a
few minutes driving.
Warning!G
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle. You

ingly.
The Minispare wheel is for temporary use
only. When driving with Minispare wheel
mounted, ensure proper tire inflation
pressure and do not exceed a vehicle speed
of 50 mph (80 km/h).

on a level surface. However, should cir-
cumstances require you to do so on a hill,
place the wheel chock and another size-
able suitable object as follows:
Place the wheel chock and another
sizeable suitable object on the downhill
side blocking both wheels of the axle
not being worked on.
Warning!G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always en-
gage the electronic parking brake and block
wheels before raising vehicle with jack.
Do not disengage electronic parking brake
while the vehicle is raised. Be certain that
the jack is always vertical (plumb line) when
in use, especially on hills. Always try to use
the jack on level surface. Make sure the jack
arm is fully seated in the jack take-up brack-
et. Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.
