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.

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 (

Vehicles with Advanced TPMS*:
The pressure is too low in one or more tires.

Carefully bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers.

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).

Only use tires which have been tested and
approved for your vehicle by Mercedes-Benz.
Tires approved by Mercedes-Benz are developed
to provide best possible performance in conjunc-
tion with the driving safety systems on your vehi-
cle such as ABS or ESP
®. Tires specially
developed for your vehicle and tested and ap-
proved by Mercedes-Benz can be identified by
finding the following on the tire’s sidewall:


MO = M
ercedes-Benz O
riginal equipment
tires
Using tires other than those approved by
Mercedes-Benz may result in damage that is not
covered by the Mercedes-Benz Limited
Warranty.
!
Using tires other than those approved by
Mercedes-Benz can have detrimental effects,
such as


poor handling characteristics


increased noise


increased fuel consumption
Moreover, tires and rims not approved by
Mercedes-Benz may, under load, exhibit dimen-
sional variations and different tire deformation
characteristics that could cause them to come
into contact with the vehicle body or axle parts. Damage to the tires or the vehicle may be the re-
sult.
i
Further information on tires and rims is
available at any authorized Mercedes-Benz
Center. A placard with the recommended tire in-
flation pressures is located on the driver’s door
B-pillar (
page 503). Some vehicles may have
supplemental tire inflation pressure information
for driving at high speeds (
page 510) or for ve-
hicle loads less than the maximum loaded
vehicle condition (
page 518). If such informa-
tion is provided, it can be found on the placard lo-
cated on the inside of the fuel filler flap.
The tire inflation pressure should be checked
regularly and should only be adjusted on cold
tires. Follow tire manufacturer’s maintenance
recommendation included with vehicle.
i
The following pages also list the approved
wheel rim and tire sizes for equipping your vehi-
cles with winter tires. Winter tires are not avail-
able as standard or optional factory equipment,
but can be purchased from an authorized
Mercedes-Benz Center.
Depending on vehicle model and the standard or
optional factory-equipped wheel rim/tire config-
uration on your vehicle (Appearance Package,
Sport Package etc.), equipping your vehicle with
winter tires approved for your vehicle model may
also require the purchase of two or four wheel
rims of the recommended size for use with these
winter tires. See an authorized Mercedes-Benz
Center for more information.

Please compare the recommended tire in-
flation pressure for your vehicle with the tire in-
flation pressure on the yellow label located on
the Minispare wheel rim.
If the tire inflation pressure on the yellow label
on the Minispare wheel rim differs from the val-
ues given in this Operator’s Manual, inflate the
spare wheel tire to the recommended tire infla-
tion pressure given on the yellow label on the
Minispare wheel rim.
i
Please note that the tire inflation pressure of
the Minispare differs from the tire inflation pres-
sure of the road tires.
Make sure the Minispare tire is inflated to ap-
proximately 61 psi (4.2 bar).

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

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

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)

System for potentially reducing braking
distances in emergency braking situa-
tions. The system is activated when it
