Warning!
When the engine is not running, both
the service brake and the steering are
w ithout power assistance. Under these
circum stances, a much greater effort
is necessary to steer or stop the
vehicle.
Emergency Engine Start
(Tow-starting)
Shift selector lever to position " N".
Turn key in steering lock to position
" 2 " and have vehicle towed.
A fter attaining a tow ing speed of
30 km /h/18 mph (with cold transm is­
sion) or 50 km /h/30 mph (with warm
transm ission), shift selector lever to
position " 3 " to tow -start the engine.
Depress accelerator fully. As soon as
the engine has started, release acce­
lerator and return selector lever to
" N " immediately.
It is im portant to allow the engine to
idle fo r at least 1 minute before
starting o ff because the preglowing
process starts when the key is in
steering lock position " 2" and is not
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
seconds, shift the selector lever from
" 3 " to " N " to pro tect the transm is­
sion from damage.
For a new starting attem pt, to w -sta rt
the vehicle fo r some tim e again with
the selector lever in position " N" and
repeat the starting procedure.
The same method can be used to
start the engine in em ergencies when
rolling downhill.
Tow-starting and Towing the Vehicle

The vehicle may be tow ed with all of
the wheels on the ground and the
sele ctor lever in position " N" fo r
distances up to 120 km /75 miles and

50 km /h /3 0 mph.
To positively avoid a possibility of
damage to the transm ission, how­
ever, we recom m end to disconnect
the drive shaft at the rear axle drive
flange on any tow ing beyond a short
to w to a nearby garage.
