The ABS malfunction indicator lamp- in the
instrument cluster comes on with the electronic key in
starter switch position 2 and should go out with the
engine running.
When the ABS malfunction indicator lamp in the
instrument cluster comes on while the engine is
running, it indicates that the ABS has detected a
malfunction and has switched off. In this case, the brake
system functions in the usual manner, but without
antilock assistance.
For ABS malfunction indicator lamp, see page 300.
With the ABS malfunctioning, the BAS and ESP are also
switched off. Both malfunction indicator lamps come on
with the engine running.
If the charging voltage falls below 10 volts, the
malfunction indicator lamp comes on and the ABS is
switched off. When the voltage is above this value again,
the malfunction indicator lamp should go out and the
ABS is operational.If the ABS malfunction indicator lamp stays illuminated,
have the system checked at your authorized
Mercedes-Benz Center as soon as possible.
Note:
To alert following vehicles to slippery road conditions
you discover, operate your hazard warning flashers as
appropriate.
Wa r n i n g !
ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded
by the condition of the vehicle brakes and tires or
the traction afforded. The ABS cannot prevent
accidents, including those resulting from excessive
speed in turns, following another vehicle too
closely, or aquaplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The
capabilities of a ABS equipped vehicle must never
be exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or the
safety of others.

The yellow ESP warning lampv in the speedometer
dial comes on with the electronic key in starter switch
position 2. It should go out with the engine running.
If the ESP warning message is displayed, a malfunction
has been detected in the system. Only partial engine
output will be available.
Have the ESP checked at your authorized
Mercedes-Benz Center as soon as possible.
For ESP warning message, see page 301.
With the ABS malfunctioning, the ESP is also switched
off.
Driving the vehicle with varied size tires will cause the
wheels to rotate at different speeds, therefore the ESP
may activate (yellow ESP warning lamp in speedometer
dial comes on). For this reason, all wheels, including the
spare wheel, must have the same tire size. When testing the parking brake on a brake test
dynamometer, the engine must be shut off. Otherwise,
the ESP will immediately be engaged and will apply the
rear wheel brakes.
In winter operation, the maximum effectiveness of the
ESP is only achieved with Mercedes-Benz recommended
M+S rated radial-ply tires and / or snow chains.
Synchronizing ESP
If the power supply was interrupted (battery
disconnected or empty), the ESP warning message may
be displayed with the engine running.
Turn steering wheel completely to the left and then to
the right. The ESP warning message should go out.

cluster displayPractical hints Car care Index Notes:
Avoid spinning of one drive wheel. This may cause
serious damage to the drive train which is not covered
by the Mercedes-Benz Limited Warranty.
The ESP warning lamp, located in the speedometer dial,
starts to f lash at any vehicle speed as soon as the tires
lose traction and the wheels begin to spin.
To return to the enhanced vehicle stability offered by
ESP: press lower half (2) of the switch (the ESP warning
lamp in the speedometer dial goes out).
Vehicles with Distronic (DTR):
With the ESP switched off, the Distronic cannot be
switched on. See page 259 for activation of Distronic.Important!
If the ESP warning lamp flashes:
•during take-off, apply as little throttle as possible,
•while driving, ease up on the accelerator.
Wa r n i n g !
ESP should not be switched off during normal
driving other than in circumstances described
above. Disabling of the system will reduce vehicle
stability in standard driving maneuvers.

3 For tire inflation pressure monitor, see page 150.4 Tire pressure in one or more tires is low. Check and correct tire
pressure, see page 348.
5 The tire pressure monitor cannot be activated with the engine
running. Turn off the engine and repeat activation, see page 150.
6 When the message appears after starting the engine, the tire
inflation pressure on all road wheels should be checked and
corrected according to the label affixed inside the fuel filler flap.
For tire inflation pressure, see page 348.
The tire inflation pressure monitor must be activated again after
the tire inflation pressure has been corrected, see page 150.
7 The tire inflation pressure monitor system is unable to monitor the
tire pressure due to the presence of several wheel electronics in
the vehicle (e.g. a deflated road wheel in the trunk), or nearby
radio interference source, or excessive wheel sensor temperatures,
or unrecognized wheel sensors mounted.
8 The tire inflation pressure monitor is defective or a wheel without
proper sensor was installed. Visit your authorized Mercedes-Benz
Center.Wa r n i n 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.

Wheels
Replace rims or tires with the same designation,
manufacturer and type as shown on the original part.
See your authorized Mercedes-Benz Center for further
information.
See your authorized Mercedes-Benz Center for
information on tested and recommended rims and tires
for summer and winter operation. They can also offer
advice concerning tire service and purchase.
Tire Replacement
Front and rear tires should be replaced in sets. Rims
and tires must be of the correct size and type. For
dimensions, see “Technical Data”.
We recommend that you break in new tires for
approximately 60 miles (100 km) at moderate speed.It is imperative that the wheel mounting bolts be
fastened to a tightening torque of 110 ft.lb. (150 Nm)
whenever wheels are mounted.
For rim and tire specifications, refer to “Technical Data”.
Wa r n i n g !
Worn, old tires can cause accidents. If the tire tread
is badly worn, or if the tires have sustained
damage, replace them.When replacing rims, use only genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can result in
the bolts loosening and possibly an accident.

The wheels can be rotated according to the degree of
tire wear while retaining the same direction of travel.
Rotating, however, should be carried out as
recommended by the tire manufacturer, before the
characteristic tire wear pattern (shoulder wear on front
wheels and tread center wear on rear wheels) becomes
visible, as otherwise the driving properties deteriorate.
Notes:
Thoroughly clean the inner side of the wheels any time
you rotate the wheels or wash the vehicle underside.
The use of retread tires is not recommended. Retread
tires may adversely affect the handling characteristics
and safety of the vehicle.
Dented or bent rims can cause tire pressure loss and
damage to the tire beads. For this reason, check rims for
damage at regular intervals. The rim f langes must be
checked for wear before a tire is mounted. Remove
burrs, if any.
Check and ensure proper tire inflation pressure after
rotating the wheels. For tire inflation pressure see
inside of fuel filler flap and also page 290.Spare wheel
Spare wheel S 430, S 500 and S 600
(except Sport Package)
Important!
The spare wheel rim is mounted with a full size tire of
the same type as on the vehicle, and is fully functional.
However, that spare wheel rim is weight optimized and
has a limited service life of 12 000 miles (20 000 km)
use before a standard wheel rim must replace it.
In the case of a flat tire, you may temporarily use the
spare wheel.
Do not operate vehicle with more than one spare wheel
mounted.
Wa r n i n g !
The spare wheel rim is for temporary use only. Use
for over a total of 12 000 miles (20 000 km)
(aggregate of all uses) may cause wheel rim failure
leading to an accident and possible injuries.

In the case of a f lat tire or breakdown, you may
temporarily use the spare wheel, while observing the
following restrictions:
•Do not exceed vehicle speed of 50 mph (80 km / h).
•Drive to the nearest repair facility to have the f lat
tire repaired or replaced as appropriate.
•Do not operate vehicle with more than one spare
wheel mounted.
For additional information, refer to page 390.
Wa r n i n g !
The spare wheel rim is for temporary use only. Use
for over a total of 12 000 miles (20 000 km) may
cause wheel rim failure leading to an accident and
possible injuries. The dimensions of the spare wheel are different
from those of road wheels. As a result, the vehicle
handling characteristics change when driving with
a mounted spare wheel.The spare wheel should only be used temporarily,
and replaced with a regular road wheel as quickly
as possible.

from the roadway.
1. Set parking brake and turn on hazard warning
flasher.
2. Move selector lever to position “P” and turn off
engine.
3. Prevent vehicle from rolling away by blocking
wheels with wheel chocks (not supplied with
vehicle) or sizable wood block or stone. When
changing a wheel on a hill, place chocks on the
downhill side blocking both wheels of the other
axle. On an level road, place one chock in front of
and one behind the wheel that is diagonally
opposite to the wheel being changed.
Wa r n i n g !
The jack is designed exclusively for jacking up the
vehicle at the jack tubes built into either side 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 firmly set parking
brake and block wheels before raising vehicle with
jack.Do not disengage parking brake while the vehicle is
raised. Be certain that the jack is always vertical
when in use, especially on hills. Always try to use
the jack on level surface. Be sure that the jack arm
is fully inserted in the jack tube. Always lower the
vehicle onto sufficient capacity jackstands before
working under the vehicle.
