The malfunction indicator lamp¿ for the ESP is
combined with that of the BAS.
The yellow BAS/ESP malfunction indicator lamp in the
instrument cluster and the yellow ESP warning
lampv in the speedometer dial come on with the
electronic key in steering lock position 2. They should
go out with the engine running.
If the BAS/ESP malfunction indicator lamp comes on
continuously with the engine running, a malfunction
has been detected in either system. Only partial engine
output will be available.
If the BAS malfunctions, the brake system functions in
the usual manner, but without BAS.
If the ESP warning message is displayed, have the BAS
or ESP checked at your authorized Mercedes-Benz
Center as soon as possible.
For ESP warning message, see page 241.
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 outside diameter.
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 BAS/ESP malfunction
indicator lamp may be illuminated with the engine
running.
Turn steering wheel completely to the left and then to
the right. The BAS/ESP malfunction indicator lamp
should go out.

Avoid spinning of a drive wheel. This may cause serious
damage to the drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
The ESP warning lamp, located in the speedometer dial,
starts to flash 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 of the switch (the ESP warning
lamp in the speedometer dial goes out).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.

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 tires should be replaced in sets. Rims and tires
must be of the correct size and type. For dimensions,
see “Technical Data” (page 312).
We recommend that you break in new tires for approx.
60 miles (100 km) at moderate speed.It is imperative that the wheel mounting bolts be
fastened to a tightening torque of 80 ft.lb. (110 Nm)
whenever wheels are mounted.
For rim and tire specifications, refer to “Technical Data”
( p a g e 312 ) .
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.

CLK 430
Wheel rotation applies only when winter tires are
mounted on all four wheels.
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.
Important!
Unidirectional tires must always be mounted with arrow
on tire sidewall pointing in direction of vehicle forward
movement.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 flanges 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 268.
