2003 MERCEDES-BENZ C320 COUPE automatic transmission

298 Practical hintsJump startingThe battery is located in the engine com-
partment on the right hand side. The
terminals for jump starting are located in
front of the battery.
Make sure that the two vehicles do not
touch.

Turn off the engine.
On both vehicles:

Turn off all electrical consumers.

Apply parking brake.

Shift selector lever to positionP (man-
ual transmission to Neutral).1Positive terminal of charged battery
2Positive under hood terminal in front of
discharged battery
3Negative terminal of charged battery
4Negative under hood terminal in front
of discharged battery

Connect positive terminal1 of the
charged battery with under hood
terminal2 in front of the discharged
battery with the jumper cables. Clamp
cable to charged battery1 first.

Start engine of the vehicle with the
charged battery and run at idle speed.

Connect negative terminal3 of the
charged battery with under hood
terminal4 in front of the discharged
battery with the jumper cables. Clamp
cable to charged battery3 first.

Start the engine of the disabled vehi-
cle.
After the engine has started, you can again
turn on the electrical consumers. Do not
turn on the lights under any circumstanc-
es.

Remove the jumper cables first from
negative terminals3 and4 and then
from positive terminals1 and2.

Have the battery checked at the
nearest authorized Mercedes-Benz
Center.
Warning!
G
Keep flames or sparks away from battery.
Do not smoke.
Observe all safety instructions and precau-
tions when handling automotive batteries
(page 231).
!Vehicles with automatic transmission:
Do not tow-start the vehicle.

299 Practical hints
Towing the vehicle
Towing the vehicle
Mercedes-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 key in starter switch turned
to position0.
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 79) and deactivate the auto-
matic central locking (
page 122).
!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
(key in starter switch position0 or1).
Otherwise, the ESP will immediately be
engaged and will apply the rear wheel
brakes.
When towing the vehicle with all wheels
on the ground, the selector lever must
be in positionN (manual transmission:
gears disengaged) and the key must be
in starter switch position2.
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).

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.
