Flexible Service System (FSS)




The FSS permits a flexible service schedule that is dire
ctly related to the operating conditions of the vehicle.
The symbol
or appears in the main odometer field prior to the next suggested service. Depending on operating
conditions throughout the year, the nex t service is calculated and displayed in days or distance remaining. The
message is displayed for approx. 10 seconds when turning the electronic key in steering lock to position 2, or it can
be canceled manually by pressing button 0. Once the suggested term has passed, the message plus symbol
or
, preceded by a - (minus symbol) blinks, when turning t he electronic key to position 2. The FSS display can also
be called up for approx.10 seconds with display illuminated by pressing button 0 twice. Following a completed service
the Mercedes-Benz dealer sets the counter to 10 000 miles (Canada: 15 000 km) and 365 days.

The counter can also be set by any individual. To do so:
1 . Turn electronic key in steering lock to position 2.
2 . Within 4 seconds press button 0 twice.
3 . The present status for days or distance is displayed. Within 10 seconds turn electronic key in steering lock to
position 0.
4 . Press and hold button 0, while turning electronic key in steering lock to position 2 again. The present status for
days or distance is displayed once more. Continue to hold button 0 After approx. 10 seconds a signal sounds, and the
display shows 10 000 miles (Canada: 15000 km).
5 . Release button 0. If the FSS counter was inadvertently reset, have a Mercedes -Benz dealer correct it.

Notes:
When disconnecting vehicle battery for one or more days at a time, such days will not be counted. Any such days not
counted by the FSS can be added by your Mercedes-Benz de aler. The interval between services is determined by
the kind of vehicle operation. Driving at extreme speeds, and cold starts combined with short distance driving in which
the engine does not reach normal operating temperat ure, reduce the interval between services.

Model C 230:
The FSS allows for distances between 10 000 miles (Canada: 15 000 km) and 15 000 miles (Canada: 22 500 km),
or from 365 to 730 days between services.

Models C 280 and C 43 AMG:
The FSS allows for distances between 10 000 miles (Canada: 15 000 km) and 20 000 miles (Canada: 30 000 km),
or from 365 to 730 days between services. However you choose to set your reference numbers, the scheduled
services as posted in the Service Booklet must be followed to properly care for your vehicle.

Acceleration Slip Regulation (ASR)
The acceleration slip regulation will engage at all vehicle s peeds, if one or both drive wheels begin to lose traction
and spin in acceleration. While engaged, the yellow warni ng lamp in the speedometer dial flashes. With the
acceleration slip regulation engaged, the brake is applied to the spinning drive wheel until slip is brought under
control. If both drive wheels spin, the brake is applied to both drive wheels and simultaneously, engine torque is
limited, to improve the vehicle's driving stability. As traction on the road surface increases, thus allowing
acceleration without slip, the allowable engine torque also increases again and the brake is no longer applied to
drive wheels.

Important !
If the ASR warning lamp flashes, adapt your spee d and driving to the prevailing road conditions.

Caution !
If the vehicle is towed with the front axle raised (see Towing the vehicle in Index), t he engine must be shut off
(electronic key in steer ing lock position 0 or 1). Othe rwise, the acceleration slip regulation will immediately be
engaged and will apply the rear wheel brakes.

Notes:
The indicator lamp for the ASR is combined with that of the BAS The yellow BAS/ASR malfunction indicator
lamp in the instrument cluster and the yellow ASR warning lamp 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/ASR malfunction
indicator lamp comes on with the engine running, a malfunc tion has been detected in either system. Pressing the
accelerator pedal will require greater effort. Only partial engine output will be available.
If the BAS malfunctions, the brake system functions in the usual manner, but without BAS. Have the BAS or ASR
checked at your authorized Mercedes-Benz dealer as soon as possible. With the ABS malfunctioning, the ASR
is also switched off. Driving the vehicle with varied size tires will cause the wheels to ro tate at different speeds,
therefore the acceleration slip regulation may activate (ye llow ASR warning lamp in speedometer dial comes on).
For this reason, all wheels, including the spare wheel, mu st have the same tire size. When testing the parking
brake on a brake test dynamometer, the engine must be shut off. Otherwise, t he acceleration slip regulation will
immediately be engaged and will apply the rear wheel brakes . In winter operation, the maximum effectiveness of
the acceleration slip regulation is only achieved with Mercedes-Benz recommended M+S rated radialply tires
and/or snow chains.

ASR Control Switch



ASR control switch located in center console To improve
the vehicle's traction when driving with snow chains, or
starting off in deep snow, sand or gravel, press the upper half of the ASR switch. The ASR warning lamp, located
in the speedometer dial, is cont inuously illuminated. With the ASR system switched off, the engine torque
reduction feature is cancelled. Therefore, the enhanced vehicle stability offered by ASR is unavailable. Adapt your
speed and driving to the prevailing road conditions. A por tion of the ASR system remains active, even with the
switch in the OFF position. If one drive wheel loses traction a nd begins to spin, the brake is applied until the wheel
regains sufficient traction. The traction control engages at vehicle speeds up to approximately 24 rnph (40 km/h),
and switches off at 50 mph (80 km/h).
Note:
Avoid spinning of one drive wheel. Doing so may cause seriou s damage to the drive train which is not covered by the
Mercedes-Benz Limited Warranty.
The ASR warning lamp, located in the speedometer dial, star ts 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 ASR: press lower
half of the switch (the ASR warning lamp in the speedometer dial goes out).

Important!
If the ASR warning lamp flashes:
• during take-off, apply as little throttle as possible,
• while driving, ease up on the accelerator.

Electronic Stability Program (ESP) (optional)

The ESP enhances directional control and reduces driving wheel spin of the vehicle under any driving condition.
Over/understeering of the vehicle is counteracted by applying brakes to the appropriate wheel to create a
counterpointing vehicle movement. The ESP warning lamp, located in the speedometer dial, starts to flash.

Important !
If the ESP warning lamp flashes, adapt your speed and driving to the prevailing road conditions.

Caution !
If the vehicle is towed with the front axle raised (see Towing the vehicle in Index), t he engine must be shut off
(electronic key in steer ing lock position 0 or 1). Otherwise, the el ectronic stability program will immediately be
engaged and will apply the rear wheel brakes.

Notes:
The 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 yello w ESP warning lamp in the speedometer di al come on with the electronic key
in steering lock position 2. They should go out with th e engine running. If the BAS/ESP multifunction indicator lamp
comes on permanently with the engine running, a malfunction has been detected in either system.
Pressing the accelerator pedal will require greater effort. Only partial engine output will be available. If the BAS
malfunctions, the brake system functions in the usual manner, but without BAS. Have the BAS or ESP checked at
your authorized Mercedes-Benz dealer as soon as possible. With the ABS malfunctioning, the ESP is also switched
off. Driving the vehicle with varied size ti res will cause the wheels to rotate at different speeds, therefore the electronic
stability program 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, t he electronic stability program will
immediately
be engaged and will apply the rear wheel brakes. In winter operation, the maximum effectiveness of the electronic
stability program is only achieved with Mercedes-Benz reco mmended M+S rated radial-ply tires and/or snow chains.
