Hood
To open:
To unlock the hood, pull release lever (1) under the driver's side of the instrument panel. At the same time handle
(2) will extend out of the radiator grill (it may be necessary to lift the hood up slightly).
Caution !
To avoid damage to the windshield wiper or hood, open the hood only with wiper in the parked position. Pull handle
(2) completely out of radiator grill and open hood (do not pull up on handle).
To close:
Lower hood and let it drop into lock from a height of approx. 1 ft. (30 cm), assisting with hands placed flat on edges
of hood (3). To avoid hood damage, if hood is not fully closed, repeat closing procedure. Do not push down on hood
to attempt to fully close it.
Warning!
To help prevent personal injury, stay clear of moving parts when the hood is open and the engine is running.
Be sure the hood is properly closed before driving. When closing hood, use extreme caution not to catch
hands or fingers. The engine is equipped with a transistorized ignition system. Because of the high voltage it
is dangerous to touch any components (ignition coils, spark plug sockets, diagnostic socket) of the ignition
system
• with the engine running,
• while starting the engine,
• if ignition is "on" and the engine is turned manually.
If you see flames, steam or smoke coming from the engine compartment, or if the coolant temperature
gauge indicates that the engine is overheated, do not open the hood. Move away from vehicle and do not
open the hood until the engine has cooled. If necessary, call a fire department.

Example
Checking Coolant Level
To check the coolant level, the vehicle must be parked on level ground and the engine stopped.
Check coolant level only when coolant is cold.
The coolant level should reach the black top part of the reservoir.
Adding Coolant
If coolant has to be added, a 50/50 mixture of water and MB anticorrosion/antifreeze should be added. The drain
plugs
for the cooling system are located on the right side of the engine block and at the bottom of the radiator.
Anticorrosion/antifreeze, see Coolants in Index.
Warning!
In order to avoid possibly serious burns or injury:
•Use extreme caution when opening the hood if there are any signs of steam or coolant leaking from the
cooling system, or if the coolant temperature gauge indicates that the coolant is overheated.
•Do not remove pressure cap on coolant reservoir if engine temperature is above 194°F (90°C). Allow
engine to cool down before removing cap. The coolant reservoir contains hot fluid and is under pressure.
•Using a rag, slowly open cap approximately 1/2 turn to relieve excess pressure. If opened immediately,
scalding hot fluid and steam will be blown out under pressure.
•Do not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes
into contact with hot engine parts.

Checking Engine Oil Level
Example
1. Oil dipstick
2. Oil filler cap
To check the engine oil level, park vehicle on level ground, with engine at normal operational temperature. Check
engine
oil level approximately 5 minutes after stopping the engine, allowing for the oil to return to the oil pan.
Oil Dipstick:
Wipe oil dipstick clean prior to checking the engine oil level. Fully insert dipstick in tube, and remove after three
seconds to obtain accurate reading.
Oil level must be between the
lower (min) and upper (max)
mark of the dipstick.
Fill quantity between upper and lower dipstick marking level is approximately 2.1 US qt (2.0 I).
Do not overfill the engine.
Excessive oil must be drained or siphoned. It could cause damage to engine and catalytic converter not covered by
the Mercedes-Benz Limited Warranty.
For low engine oil level warning lamp, see Index.

Odometer Display Field
(Models C 280 and C 43 AMG)
Turn electronic key in steering lock to position 2 and wait until the symbols and appears in the
odometer display field. Within 1 second press button 0 twice.
The following messages are available:
"OK"
"-1.0 Q" (Canada: -1.0 L)
"-1.5 Q" (Canada: -1.5L)
"-2.0 Q" (Canada: -2.0 L)
If the message "-2.0 Q" (Canada: -2.0 L) blinks and a signal sounds, add oil to upper (max) mark of the dipstick.
"HI"
The message "Hi" blinks and a signal sounds.
Do not overfill the engine.
Excessive oil must be drained or siphoned. It could cause damage to engine and catalytic converter not covered
by the Mercedes-Benz Limited Warranty.
The symbol flashes in the odometer field if a proper oil level check cannot be performed. The oil level check
can be repeated after a short while. Perform the oil level check with the dipstick, if it cannot be completed via the
odometer display field. In this case we recommend that you have the system checked at a Mercedes-Benz dealer.
Notes:
If the symbols and are continuously illuminated after pressing button 0 twice and there is no change in the
odometer display field or the low engine oil level warning lamp comes on, a malfunction has occurred to the system .
Perform the engine oil level check with the dipstick. If no oil leaks are noted continue to drive to the nearest
Mercedes-Benz dealer to have the system checked.
Automatic Transmission Fluid Level
The transmission has a permanent fill of automatic transmission fluid. Regular automatic transmission fluid
level checks and changes are not required. For this reason the dipstick is omitted. If you notice fluid leaks or
gear shifting malfunctions, have your authorized Mercedes-Benz dealer check the transmission fluid level.

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.

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.

Wheels
Replace rims or tires with the same designation, manufacturer and type as shown on the original part. See your
authorized Mercedes-Benz dealer for further information. See your authorized Mercedes-Benz dealer for information
on tested and recommended rims and tires for summer and wi nter 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". We recommend that you break in new ti res 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".
Warning !
Worn, old tires can cause accidents. If the tire tread is badly worn, or if the tires have sustained damage, replace
them. When replacing rirns, use only genuine Mercedes-Benz w heel bolts specified for the particular rim type. Failure
to do so can result in the bolts loosening and possibly an accident.
Rotating Wheels
Rotation of wheels with summer tires does not apply to m odel C 43 AMG. 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 at the
scheduled service intervals, 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 charac teristics and safety of the
vehicle. Dented or bent rims can caus e 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 refer to
Index.
Spare Wheel (except C 43 AMG)
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 an d 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.
Unidirectional tires must always be mounted with arrow on tire sidewall pointing in direction of vehicle forward
movement. If the arrow on tire side wall does not point in direction of vehicle forward movement when using the spare
wheel, observe the following restrictions:
• Drive to the nearest tire repair facility as soon as possible.
For rim and tire specifications, refer to "Technical Data".
Warning !
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.

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.
