Warning !
When leaving the vehicle always remove the electronic key from the steering lock, and lock the vehicle.
Do not leave children unattended in the vehicle, or with access to an unlocked vehicle.
Unsupervised use of vehicle equipment may cause serious personal injury.


Important !
If the electronic key is left in the steering lock position 0 for an extended period of time, it can no longer be turned
in the lock. In this case, remove electronic key from steering lock and reinsert.

Notes:
A warning sounds when the driver's door is opened with the electronic key in steering lock position 1 or 0. With the
engine at idle speed, the charging rate of the alternator (output) is limited. It is therefore recommended to turn off
unnecessary electrical consumers while driving in stop-and-go traffic. This precaution helps to avoid draining of the
battery. Unnecessary strain on the battery and charging system may be minimized by turning off the following power
consumers, for example: Heated seats, rear window defroster. In addition, the automatic climate air volume control
should be set to the lowest position. The steering lock can only be unlocked with the vehicle battery properly
connected.

Caution !
To prevent accelerated battery discharge and a possible dead battery, always remove the electronic key from the
steering lock. Do not leave the electronic key in steering lock position 0.

Flexible Service System (FSS)





The FSS permits a flexible service schedule that is directly 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 next 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
while driving when reaching the service warning threshold. It can be cancelled manually by pressing button 0.
Once the suggested term has passed, the message plus symbol or , preceded by a - (minus symbol) blinks for
approx 20 seconds and a signal sounds every time when turning the electronic key in steering lock to position 2. The
FSS display
can also be called up for approx.10 seconds with display illuminated by pressing button 0 twice within 1 second.
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) for approx. 10 seconds.
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 dealer. 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 temperature, reduce the interval between services.

Model C 230 Kompressor:
The FSS allows for distances between 10 000 miles (Canada: 16 000 krn) and 15 000 miles (Canada: 25 000 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.

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), the engine must be shut off
(electronic key in steering lock position 0 or 1). Otherwise, the ESP 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 yellow ESP 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/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 tires will cause the wheels to rotate at different speeds, therefore the electronic
stability program may activate (yellow ESP warning lamp in speedometer dialcomes 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 electronic stability program 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 multifunction 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.

ESP Control Switch




ESP control switch located on 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 ESP switch. The ESP warning lamp, located in
the speedometer dial, is continuously illuminated. With the ESP system switched off, the engine torque reduction
feature is cancelled. Therefore, the enhanced vehicle stability offered by ESP is unavailable. Adapt your speed and
driving to the prevailing road conditions. A portion of the ESP system remains active, even with the switch in the OFF
position.
If one drive wheel loses traction and begins to spin, the brake is applied until the wheel regains sufficient traction.
The traction control engages at vehicle speeds up to approximately 24 mph (40 km/h), and switches off at
50 mph (80 km/h).

Note:
Avoid spinning of one drive wheel. Doing so 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 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).

Winter Driving
Have your car winterized at your authorized Mercedes-Benz dealer before the onset of winter.
• Change the engine oil if the engine contains an oil which is not approved for winter operation.
For viscosity (SAE/CCMC class) and filling quantity, see Capacities: Fuels, Coolants,
Lubricants etc. in Index.
• Check engine coolant anticorr osion/antifreeze concentration.
• Additive for the windshield washer and headl amp cleaning system: Add MB Concentrate "S"
to a premixed windshield washer solvent/ant ifreeze which is formulated for below freezing
temperatures (see Index).
• Test battery: Battery capacity drops with dec reasing ambient temperature. A well charged
battery helps to ensure that the engine can be started, even at low ambient temperatures.
• Tires: We recommend M+S rated radial-ply tires on all four wheels for the winter season.
Observe permissible maximum speed for M+S rated radial-ply tires and the legal speed limit.

Note:
In winter operation, the maximum effectiveness of the Antilock Brake System (ABS), Acceleration Slip Regulation
(ASR) or the Electronic Stab ility Program (ESP) can only be achieved with M+S rated radial-ply tires and/or snow
chains recommended by Mercedes-Benz. Snow chains maximize performance.


Snow Chains
Use only snow chains that are tested and recommended by Mercedes-Benz. Your authorized Mercedes-Benz
dealer will be glad to advise you on this subject. Ch ains should only be used on the rear wheels.
Follow the manufacturer's mounting instructions. Snow ch ains should only be driven on snow covered roads at
speeds not to exceed 30 mph (50 km/h). Remove chains as soon as possible when driving on roads without snow.
For tips on driving on slippery winter roads, refer to In dex. Vehicles with Acceleration Slip Regulation (ASR) or
Electronic Stability Program (ESP): When driving with snow chains, press the ASR or ESP control switch, refer to
Index.


Model C 43 AMG

Important !
Use of snow chains is permissible only on winter tire size 215/45 R 17 H M+S. Refer to "Rims - Tires" in section
"Technical Data" (see Index).


Travelling Abroad
Abroad, there is a widely-spread Mercedes-Benz service network at your disposal. If you plan to travel into areas
which are not listed in the index of your dealer directory, you should request pertinent information from your
authorized Mercedes-Benz dealer.

Trunk Lamp
If the trunk is to remain open for a long period of time, the trunk lamp can be switched off by pulling out the plunger
in the switch (arrow). This prevents the vehicle battery from being discharged. When the trunk lid is closed, the switch
will reset and turn on the lamp next time the lid is opened.


Stowing Things in the Vehicle

Warning !
To help avoid personal injury during a collision or sudden maneuver, exercise care when stowing things.
Put luggage or cargo in the trunk if possible. Do not pile luggage or cargo higher than the seat backs.
Do not place anything on the shelf below the rear window.

Battery

Warning !
Failure to follow these instructions can result in severe injury or death. Never lean over batteries while
connecting, you might get injured. Battery fluid contains sulfuric acid. Do not allow this fluid to come in
contact with eyes, skin or clothing. In case it does, immediately flush affected area with water and seek
medical help if necessary. A battery will also produ ce hydrogen gas, which is flammable and explosive.
Keep flames or sparks away from battery, avoid im proper connection of jumper cables, smoking etc..

Important !
Battery maintenance information:
The battery is located in the trunk under the trunk floor. The fluid level must be checked at every A and B service.
Always insure that the fluid level is at the specified maximum level and that only distilled water is used. Failure to
maintain proper fluid level may result in cell deterioration and possible battery rupture. The service life of the battery is
dependent on its condition of charge. The battery should alwa ys be kept sufficiently charged, in order to last an
optimum length of time.
Therefore, we strongly recommend that you have the battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than approximately 200 miles (300 km) per month, mostly for
short distance trips, or if it is not used for long periods of time.
Only charge a battery with a battery charger after the battery has been disconnected from the vehicle electrical circuit.
Always disconnect the battery negative lead first and connect last. When removing and connecting the battery,
always make sure that all electrical consumers are off and the electronic key is in steering lock position 0. The battery
and its vent tube must always be securely installed when the car is in operation. While the engine is running the
battery terminal clamps must not be loosened or detached, otherwise the generator and other electronic components
would be damaged.

Note:
After reconnecting the battery also resynchronize the Express feature of the power windows, the
sliding/pop-up roof, and the Electronic Stability Program (ESP) (see Power seats, front, Head
restraints, Power windows, Sliding/pop-up roof, and Electronic stability program in Index).

Battery Recycling
Batteries contain materials that can harm the environment with improper disposal. Large 12 Volt storage batteries
contain lead. Recycling of batteries is the preferred method of disposal. Many states require sellers of batteries to
accept old batteries for recycling.

Jump Starting

Warning !

Failure to follow these directions will cause damage to the electronic components, and can
lead to a battery explosion and severe injury or death. Never lean over batteries while
connecting or jump starting, you might get injure d. Battery fluid contains sulfuric acid. Do
not allow this fluid to come in contact with ey es, skin or clothing. In case it does, immediately
flush affected area with water, and seek medical help if necessary. A battery will also produce
hydrogen gas, which is flammable and very explosive. Keep flames or sparks away from
battery, avoid improper connection of jumper cables, smoking etc.. Read all instructions
before proceeding.

If the battery is discharged, the engine should be start ed with jumper cables and the (12 V) battery of
another vehicle.
The battery is located in the trunk under the trunk floor.

Proceed as follows:
1 . Position the vehicle with the charged battery so that the jumper cables will reach, but never
let the vehicles touch. Make sure the jump er cables do not have loose or missing insulation.
2. On both vehicles:
• Turn off engine and all lights and accessories, except hazard warning flashers or work lights.
• Apply parking brake and shift selector lever to position "P".

Important !
3. Clamp one end of the first jumper cable to the positive (+) terminal of the discharged
battery and the other end to the positive (+ ) terminal of the charged battery. Make sure
the cable clamps do not touch any other metal parts.
4. Clamp one end of the second jumper cable to the grounded negative (-) terminal of the
charged battery and the final connection to the negative (-) terminal of the discharged battery.


Important !
5. Start engine of the vehicle with the charged battery and run at high idle. Make sure the
cables are not on or near pulleys, fans, or other parts that will move when the engine is
started. Allow the discharged battery to charge for a few minutes. Start engine of the
disabled vehicle in the usual manner.
6. After the engine has started, remove jumper cables exactly reversing the above
installation sequence, starting with the last connection made first. When removing each
clamp, make sure that it does not touch any other metal while the other end is still attached.


Important !
A discharged battery can freeze at approx. +14°F (-10°C ). In that case, it must be thawed out before
jumper cables are used. A frozen battery can explode and cause personal injury.

Jumper cable specifications:
• Minimum cable cross-section of 25 mm
2 or approx. 2 AWG
• Maximum length of 11.5 ft. (3.5 m).


Note:
If engine does not run after several unsuccessful starting attempts, have it checked at the nearest
authorized Mercedes-Benz dealer. Excessive unbur ned fuel may damage the catalytic converter.
