Possible cause/consequence
Possible solution
Tire pressure
Check tires
The pressure has fallen significantly in one
or more tires.
Carefully bring the vehicle to a halt, avoiding abrupt steering
and braking maneuvers. Observe the traffic situation around
you.
Check and adjust tire inflation pressure as required
(page 511).
If necessary, change the wheel (
page 629).
Restart the Run Flat Indicator* after adjusting the tire infla-
tion pressure values (
page 516).
Tire pressure monitor
inoperative
The Advanced TPMS* or a wheel sensor is
malfunctioning.
Have the Advanced TPMS* checked by an authorized
Mercedes-Benz Center.
Tire pressure monitor
inoperative
No wheel sensors
The Advanced TPMS* is deactivated be-
cause wheels without proper sensors were
installed.
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 sever-
al minutes.
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.

Possible cause/consequence
Possible solution
Tire pressure monitor
currently unavailable
The 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.
Tire pressures
displayed after driving
a few minutes
Vehicles with Advanced TPMS*:
The tire inflation pressure is being checked.
Drive the vehicle for a few minutes.
Visit workshop
without shifting gears
The automatic transmission cannot be shift-
ed out of the set position because of a mal-
function.
If the automatic transmission is shift to positionD:
Without changing the automatic transmission from
positionD, drive to an authorized Mercedes-Benz Center.
If the automatic transmission is shift to positionN, R or P:
Do not drive.
Consult an authorized Mercedes-Benz Center.

Tele Aid
inoperative
One or more main functions of the Tele Aid

Caution, tire defect
Vehicles with Advanced TPMS*:
One or more tires are deflating.
Carefully bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers.
If necessary, change the wheel (

Possible cause/consequence
Possible solution
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.
Have the Advanced TPMS* checked by an
authorized Mercedes-Benz Center.
Have the wheel sensors installed by an
authorized Mercedes-Benz Center.
The tire pressure for the respective tire is
shown in the multifunction display after a few
minutes driving.
Tire pressure
Please rectify
Vehicles with Advanced TPMS*:
The pressure is too low in one or more tires.
Or the tire pressures of the individual
wheels differ too radically from one anoth-
er.
Check and adjust tire inflation pressure as
required (
page 514).

669 Technical terms
ABC
(A
ctive B
ody C
ontrol)
Active, computer-controlled system
that hydraulically adjusts the suspen-
sion at all four wheels in response to
various driving situations.
ABS
(A
ntilock B
rake S
ystem)
Prevents the wheels from locking up
during braking so that the vehicle can
continue to be steered.
Accessory weight
(

Adaptive Brake
Brake system that is coupled with
->ABS, ->ESP and ->BAS. Adaptive
Brake takes driver and vehicle charac-
teristics into consideration, thus
achieving an optimal braking effect.ADS
(A
daptive D
amping S
ystem)
Automatically adapts the optimum sus-
pension damping to prevailing driving
conditions.
Advanced TPMS*
(T

ressure M
onitoring S
ystem)
The Advanced TPMS monitors the tire
inflation pressure in all four tires. A
warning is issued to alert you to a de-
crease in pressure in one or more of
the tires. Tire inflation pressure inquir-
ies are made using the ->Instrument
cluster control system.
Airmatic
Automatically selects the optimum sus-
pension tuning and ride height for your
vehicle. Airmatic consists of two com-
ponents:

Alignment bolt
Metal pin with thread. The centering
pin is an aid used when changing a tire
to align the wheel with the wheel hub.
A-pillar
Front connecting pillar between the
roof and the vehicle body (->B-pillar,
->C-pillar).
Aspect ratio
(page 526)
Bar
(page 526)
BAS
(Brake A
ssist S
ystem)
System for potentially reducing braking
distances in emergency braking situa-
tions. The system is activated when it
senses an emergency based on how
fast the brake is applied.
