Tow-starting and Towing the Vehicle
Please keep in mind that considerably
more effort is necessary to steer and
brake the car while the engine is not
running since there is no servo-
assistance.
Emergency Engine Start
(Tow-starting)
Shift selector lever to " N" and turn
key in steering lock to position "
Have vehicle towed. Having attained a
speed of 30 km/h/18 mph — cold
transmission — or 50 km/h/30 mph
— warm transmission — keep on
driving at this speed for approxi­
1
mately minute to ensure sufficient
fluid pressure in the transmission.
To crank the engine, shift selector
lever to ''3" . Depress accelerator
fully. As soon as the engine has
started, release accelerator and
return selector lever to " N" immedia­
tely.

It is important to allow the engine to
1
idle for at least minute before
starting off because the preglowing
process starts when the key is in
steering lock position "
immediately disrupted after the
engine has been tow-started. During
this time the preglowing process is
cut out automatically.
If the engine has not fired after a few
2
" .
seconds, shift the selector lever from
" 3" to " N" to protect the transmis­
sion from damage.
For a new starting attempt, tow-start
the vehicle for some time again with
the selector lever in position " N" and
repeat the starting procedure.
The same method can be used to
start the engine in emergencies when
rolling downhill.
Towing a Vehicle
The vehicle may be towed with all of
the wheels on the ground and the
selector lever in position " N" for
2
" and is not
distances up to 120 km/75 miles and
at a speed not to exceed
50 km/h/30 mph.
To positively avoid a possibility of
damage to the transmission, how­
ever, we recommend to disconnect
the drive shaft at the rear axle drive
flange on any towing beyond a short
tow to a nearby garage.
Front tow ing: Attach J-hooks to the
subframe crossmember. Position towba
under the radiator support. Attach safety
chains to the lower control arms, betwe<
the springs and shock absorbers.
Rear towing: Attach T-hooks to the
tie-down slots. Position towbar under re
of trunk floor. Attach safety chains to the
lower control arms.
