Tele Aid
Inoperative
One or more main functions of the Tele Aid
system are malfunctioning.
Have the Tele Aid system checked by an au-
thorized Mercedes-Benz Center.
Check
Tire Pressure
The pressure is too low in one or more tires.
Carefully bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers.
Engage the electronic parking brake
(page 422).
Check and adjust tire inflation pressure as
required (
page 593).
If necessary, change the wheel (
page 723).
Tire Press. Warning
Caution
Tire Malfunction
One or more tires are deflating.
Carefully bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers.

Caution
Tire Defect
One or more tires are deflating. The respec-
tive tire is shown in the multifunction dis-
play.
Carefully bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers.
Engage the electronic parking brake
(page 422).
If necessary, change the wheel (
page 723).
Warning!
G
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.
Follow recommended tire inflation pres-
sures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adverse-
ly 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) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes
etc.

Wheel Sensor(s)
Missing
One or more sensors malfunction (e.g. bat-
tery in one or more wheel sensor is empty).
One or more wheels without wheel sensors
mounted (e.g. spare tire).
No pressure value is shown on the multi-
function display for the tire in question.

Or the tire pressures of the individual
wheels differ too radically from one anoth-
er.
Check and adjust tire inflation pressure as
required (
