Starting a cold engine
• At ambient temperatures down to -155C, pull the cold start knob out fully before operating the sta rter .
At lower t em pe rature s, the knob should not
be pulle d out until engine is firing reg­ularly -the engine wi ll then start more
readily .

Turn the key in the igniti on lock to posi­
tion 2 (see page 35) -the glow plug wa rning
lamp comes on. It goes out when the igni­
t ion tempera ture is reached (see page 47) While the glow plugs are working do not switch on any other heavy cur­rent consumers because this would place an unnecessary load on the battery.

If the
engine only fire s irregul arly, continue to ope rate the starter a few seconds longer (30 seconds at maximum) until the engine
runs under its own power. If
the eng ine does not start , switch the g
low plugs on again and try starting it again as de­
scr ibed . If th e eng ine still doe s not start the
fuse for the glow plugs may have blown ­

Stopping engine
66 kW engine
Starting a cold engine
Ambient temperature above +5 0C:

The engine can be started without pre­
glow Do not depress throttle during the

starting procedure.

Ambient temperature below +5 0C:

• Turn the key in the ignition lock to posi­
tion 2 (see page 35) -the glow plug warning
lamp comes on It goes out when the igni­
tion temperature is reached (see page 47). While the glow plugs are working do not switch on any other heavy cur­rent consumers because this would place an unnecessary load on the battery.
• When the warning lamp goes out, start
the engine immediately
If the engine does not start, repeat
preglow and try starting it again as described. If the
engine still does not start the fuse for the glow plugs may have blown -see page 120.
Starting a warm engine
The glow plug lamp does not come on -the
engine can be started straight away
When engine has been running fast for a long time, let it idle for about 2 minutes so that it can cool down slightly before being switched off.
Attention After the engine has been stopped the fan can continue running for a while (up to about 10 minutes) with the ignition switched off. It can also start to run again suddenly after a short time if -the coolant temperature in­creases due to heat build-up
-when engine is hot and the en­gine compartment is heated additionally by strong sun­light.
Special care must therefore be taken when working in the en­gine compartment.
On vehicles with a catalytic con­verter, the ignition must not be switched off as long as the vehicle is rolling with a gear engaged, other­wise, unburnt fuel can pass into the catalytic converter and cause dam­age.

Warning lamps
Attention • Be careful when opening the coolant expansion tank! When the engine is hot the cooling sys­tem is under pressure -Danger of scalding! Let engine cool down therefore before unscrewing the cap_
• Do not touch the fan. The fan can switch on suddenly -even when ignition is switched off.
For furthe r details see pages 98 and 98.

Operating instructions
• Ensure that the sensor betvveen the
windscreen defrost outlets in the centre of
the instrument panel and the air grille next
to the radio is not covered.
• If, after switching on the ignition,
all sym­
bols in the display area flash for about 15
seconds, there is a fault in the system -con­
tact a Volkswagen dealer.
Notes for both air conditioning
systems
• To ensure that the heating, ventilation
and air conditioner can work properly, the air
inlet in front of the windscreen should be
kept free of ice, snow and leaves.
• The heat output depends
on the coolant
temperature -the full heat output is there­
fore available when the engine IS warm.
• The stale air escapes through openings
in the luggage compartment side panels.
Therefore when loading the luggage com­
partment ensure that the openings are not
covered .
• When the ambient temperature
is high
and the air very humid, condensed water can drip off the evaporator and form a
puddle under the vehicle. This is quite nor­
mal and does not indicate a leak.
Notes for the normal air condi­
tioner
• All controls except the rotar y switch A and buttons 0 and E can be set to any inter­
mediate position.
•
To prevent the windows from misting up
the blower should be running slowly when driving at low speeds.
Using air conditioners economi­
cally
In cooling operation the air conditioner com­
pressor places demands on the engine and
therefo re influences the fuel consumption.
To keep the period switched on as short as possible, the following points should be
noted:
• If the
in side temperature is very high
after the car has been parked in the sun, it is recommended to open doors or windows briefly to enable the hot air to escape
• The air conditioner should not be
switched on during a Journey if the
windows or sliding/tilting roof* are open.
• If the desired interior temperature
can be attained w ithout switching on the air
cond itioner the fresh air operation should
be selected (does not apply to Climatronicl.
Operating faults
• Should the air cond i:ioner not work at
any time, either .
- the ambient temperatu re IS below about +5 °C,
-or the fuse has blown.

Check fuse and if necessary r
enew it - see

page 119. If the troub le is n ot due to a defec­

tive fuse, SWitch the system off and have It
checked.

- the air conditioner
has svvitched off due

to coolant temperature being too high -see
page 45.
• If the cooling output drops off, switch
the AlC
off and have the system checked.

Downloaded from www.Manualslib.com manuals search engine DRIVING TIPS

Driving instructions
To obtain the best possible handling of ve­
hicle and trailer, the following should be
noted :
•
Try to avoid driving w ith an unladen ve­
hicle and a loaded trailer. If this cannot be
avoided, only drive
slowly to allow for the
unfavourable weight distribution .
• As driving stability
of vehicle and trailer
decreases when the speed increases do not drive at the maximum permissible top speed in unfavourable road, weather or wind conditions -particularly when going
downhill.
In any case the speed must be reduced im­
mediately the trailer shows the slightest
sign of snaking . On no account try to stop
the snakin g by accelerating.
• For safety reasons one should not drive
faster than 80
km/h (50 mph). This also
applies in countries where higher speeds
are permitted. •
Al
ways brake in good time. If the trailer
has an overrun brake, apply the brakes gen­
tl y at firs t then firmly. This will avoid the Je rk­
ing caused by the trailer wheels loc king. Change down before going down a steep
hill so that the engine can act as a braka.
•
When a lon g climb in a low gear with ex­
tremel y high engine revs must be nego­
tiated at exceptionally high ambient tem­peratures the coolant temperature gauge must be observed. When the gauge needle
moves to the upper end of the scale, the
road speed must be reduced immediately
If nevertheles s the warning lamp flashes,
stop
immediatel y and allow the engine to
cool off at id l ing speed for several minutes.
• The coo ling
effect of the radiator fan can­
not be increased by changing down, be­
cause the speed of the fan is not dependent
on the engine speed. One should the refore
not change down even when towing a
trailer as 10ll g as the engine can cope with­out the vehicle speed dropping too much .
General notes
• It is advisable to hav e the vehicle ser­viced between the Insp ection in tervals it it
is used frequently for towing a trailer .
• The trailer and draw
bar load figures on
the data plate of the towing bracke t are for test ce rtific ation only. The correct figures
for the vehicle, which may be lower t han
th ese figures, are given in the eh icle docu­ments and in this manual.

Attention
Particular care should be taken
when working in the engine com­
partment!

• Switch off engine. remove ignition key_
•
Pull handbrake on firmly.
• Move gear lever into neutral or
"P" position.

• Allow engine to cool off.
• As long as the engine is at op­
erating temperature:
-Do not put your hand into the
radiator fan. it could switch on
suddenly.
-Do not open the radiator cap be­
cause the cooling system is
under pressure.
• Avoid causing short circuits in
the electrical system -particu­
larly at the battery -.

• If tests have to be ca rried o ut with the engine running. there is an additional dang e r present from rotating parts - e.g . ribbedl V-belts, alternator, ra d iator fan etc. -and fro m the high voltage ignition system.
Attention m ust be paid to the w arn ings given in this Instruc­tion Manual and to the generally ap plicable safety regulations.
When topp ing up fluids one should ensure that they are not mistaken. one for the other, under any circum ­stances. otherwise serious fu nc­tional defects will result.
rJjh So that leaks are quickly de­(!J!J tected the ground underneath the vehicle should be checked reg­ularly. If spots as caused by oil or other operating fluids can be seen, the vehicle should be taken to the workshop for checking.
