2005 MERCEDES-BENZ C CLASS COUPE automatic transmission

406 Practical hintsTowing the vehicleMercedes-Benz recommends that the vehi-
cle be transported with all wheels off the
ground using flatbed or appropriate wheel
lift/dolly equipment. This method is pref-
erable to other types of towing.When circumstances do not permit the
recommended towing methods, the vehi-
cle may be towed with all wheels on the
ground or front wheels raised only so far as
necessary to have the vehicle moved to a
safe location where the recommended
towing methods can be employed.
!Use flatbed or wheel lift/dolly equip-
ment with SmartKey in starter switch
turned to position
0.
Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
To prevent damage during transport,
do not tie down vehicle by its chassis or
suspension parts.
Switch off the tow-away alarm
(page 87) and deactivate the auto-
matic central locking (
page 148).
!Vehicles with automatic transmission:
Do not tow-start the vehicle.
!If the vehicle is towed with the front
axle raised, the engine must be shut off
(SmartKey in starter switch position 0
or 1). Otherwise, the ESP will immedi-
ately be engaged and will apply the rear
wheel brakes.
When towing the vehicle with all wheels
on the ground, the gear selector lever
must be in position N (manual trans-
mission: gears disengaged) and the
SmartKey must be in starter switch
position 2.
When towing the vehicle with all wheels
on the ground or the front axle raised,
the vehicle may be towed only for dis-
tances up to 30 miles (50 km) and at a
speed not to exceed 30 mph
(50 km/h).

438 Technical termsControl systemThe control system is used to call up
vehicle information and to change
component settings. Information and
messages appear in the multifunction
display. The driver uses the buttons on
the multifunction steering wheel to
navigate through the system and to ad-
just settings.
Cruise control Driving convenience system for auto-
matically maintaining the vehicle speed
set by the driver.

Engine number The number set by the manufacturer
and placed on the cylinder block to
uniquely identify each engine pro-
duced. Engine oil viscosity
Measurement for the inner friction (vis-
cosity) of the oil at different tempera-
tures. The higher the temperature an
oil can tolerate without becoming thin,
or the lower the temperature it can tol-
erate without becoming viscous, the
better the viscosity.
ESP (E

Improves vehicle handling and direc-
tional stability.
ETD (E
mergency T
ensioning D

Device which deploys in certain frontal
and rear collisions exceeding the sys-
tem's threshold to tighten the seat
belts.
->SRS FSS (Canada vehicles)
(F

Maintenance service indicator in the
multifunction display that informs the
driver when the next vehicle mainte-
nance service is due. FSS evaluates
engine temperature, oil level, vehicle
speed, engine speed, distance driven
and the time elapsed since your last
maintenance service, and calls for the
next maintenance service accordingly.

Overspeed range Engine speeds within the red marking
of the tachometer dial. Avoid this en-
gine speed range, as it may result in se-
rious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty. Poly-V-belt drive
Drives engine-components (alternator,
AC compressor, etc.) from the engine.
