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).
Emission Control
Certain systems of the engine serve to keep the toxic components of the exhaust gases within permissible limits
required by law. These systems, of course, will function properly only when maintained strictly according to factory
specifications. Any adjustments on the engine should, ther efore, be carried out only by qualified Mercedes-Benz
authorized dealer technicians. Engine adjustments should not be altered in any way. Moreover, the specified service
jobs must be carried out regularly according to Mercedes -Benz servicing requirements. For details refer to the
Service Booklet.
Warning !
Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide, and
inhaling it can cause unconsciousness and lead to death.
Do not run the engine in confined areas (such as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are entering the vehicle while driving, have the cause determined and
corrected immediately. If you must drive under these conditions, drive only with at least one window fully
open.
On-Board Diagnostic System
The Sequential Multiport Fuel Injection (SFI) control module monitors emission control components that either provide
input signals to or receive output sign als from the control module. Malfunctions resulting from interruptions or failure
of any of these components are indica ted by the "CHECK ENGINE" malfunction indicator lamp in the instrument
cluster and are simultaneously stored in the SFI control module. If the "CHECK ENGINE" malfunction indicator lamp
comes on, have the system checked at your authorized Mercedes-Benz dealer as soon as possible. With some
exceptions the control module switches off the "CHECK ENGINE" indicator lamp if the condition, causing the lamp to
come on, no longer exists during three consecutive cycles. An on-board diagnostic connector is located in the
passenger compartment near to the parking brake pedal, allowi ng the accurate identification of system malfunctions
through the readout of diagnostic trouble codes.
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.
Vehicle Jack
1. Jack arm
2. Jack base
See illustration for proper storage of jack. Before storing the jack on the felt in the spare wheel well, the jack arm
must be lowered almost to the base of the jack.
Warning !
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.
Spare Wheel for Model C 43 AMG
The spare wheel rim size is 71/2 J x 17 H2
In the case of a flat tire or breakdown, you may temporarily use a 71/2 J x 17 H 2 instead of the
81/2 J x 17 H 2 wheel rim on the rear axle, when observing the following restrictions:
• Do not exceed vehicle speed of 50 mph (80 km/h).
• Drive to the nearest repair facility to have the flat tire repaired or replaced as appropriate.
For additional information, refer to "Technical Data".
Warning !
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.

Changing Wheels
Move vehicle to a level area which is a safe distance from the road way.
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 a level road, place one chock in front of and one behind the wheel that is
diagonally opposite to the wheel being changed.
4. Using the wrench, loosen but do not yet remove the wheel bolts.
5. Remove the protective cover from the jack support tube opening by inserting the
screwdriver (supplied in the tool kit) in the opening and prying it out. The tube
openings are located directly behind the front wheel housings and in front of the
rear
wheel housings.
6. Insert jack arm fully into the tube hole up to the stop.
Place jack on firm ground. Position the jack so that it is always vertical (plumb-line)
as seen from the side (see arrow), even if the vehicle is parked on an incline.
7. Jack up the vehicle until the wheel is clear of the ground.
Never start engine while vehicle is raised.
8. Unscrew upper-most wheel bolt and install alignment bolt (1) supplied in the
tool kit. Remove the remaining bolts. Keep bolt threads protected from dirt and
sand.
9. Remove wheel. Grip wheel from the sides. Keep hands from beneath the wheels.
10.Clean contact surfaces of wheel and wheel hub. Install spare wheel on wheel hub.
Insert wheel bolts and tighten them slightly. To avoid paint damage, place wheel
flat
against hub and hold it there while installing first wheel bolt.
Unscrew the alignment bolt (1) to install the last wheel bolt.
11.Lower car. Remove jack and insert jack tube cover.
Before storing the jack, the jack arm must be lowered almost to the base of the jack.
Warning !
Always replace wheel bolts that are damaged or rusted.
Never apply oil or grease to wheel bolts. Damaged wheel hub threads should
be repaired immediately.
Incorrect mounting bolts or improperly tightened mounting bolts can cause the
wheel to come off. This could cause an accident. Be sure to use the correct
mounting bolts.
12. Using the wrench, tighten the five bolts evenly, following the sequence illustrated,
until all bolts are tight. Observe a tightening torque of 80 ft.lb. (110 Nm).
13. Ensure proper tire pressure.
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.
Towing the Vehicle
Warning!
Prior to towing the vehicle with all wheels on the ground, make
certain that the electronic key is in steering lock position 2.
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, the steering is locked. To unlock, remove
electronic key from steering lock and reinsert.
Important !
When towing the vehicle, please, note the following:
With the automatic central locking activated and the electronic key inn steering lock position 2, the vehicle
doors lock if the left front wheel as well as the right rear wheel are turning at vehicle speeds of approx. 9 mph (15
km/h) or more. To prevent the vehicle door locks from locking, deactivate the automatic central locking.
All except C 43 AMG
The rear towing eye is located at the right, below the bumper. The front towing eye is located on the passenger side
behind a cover in the bumper panel.
Models C 230 Kompressor and C 280:
Cover removal:
Insert finger in recess on left end of cover and pull cover out.
Cover installation:
Engage cover at top right and press cover in securely.
C 43 AMG
Model C 43 AMG
Cover removal:
Hold left and right end of cover and pull out.
Cover installation:
Engage cover at bottom and press in top securely.
We recommend that the vehicle be transported using flat bed equipment. This method is preferable to other types of
towing. The vehicle may be towed with all wheels on the ground and the selector lever in position "N" for distances up
to 30 miles (50 km) and at a speed not to exceed 30 mph (50 km/h). The electronic key must be in steering lock
position 2. To positively avoid a possibility of damage to the transmission, however, we recommend to disconnect the
drive shaft at the rear axle drive flange on any towing beyond a short tow to a nearby garage. Do not tow with sling-
type equipment. Towing with sling-type equipment over bumpy roads will damage radiator and supports. Use wheel
lift, dolly, or flat bed equipment, with electronic key in steering lock turned to position 0.
Warning !
With the engine not running, there Is no power assistance for the braking and steering systems.
In this case, it is important to keep in mind that a considerably higher degree of effort is necessary
to brake and steer the vehicle.
Note:
To signal turns while being towed with hazard warning flasher in use, turn electronic key in steering lock
to position 2 and activate combination switch for left or right turn signal in usual manner - only the
selected turn signal will operate. Upon cancelling the turn signal, the hazard warning flasher will operate again.
