Catalytic converter for petrol
eng ines
Leaded fuel will damage the catalytic
converter and parts of the electronic
system, thereby rendering them
inoperative.
On vehicles with a catalytic converter, the
fuel ta nk filler neck is of a narrow design so
that a dispensing pump for leaded fuel
cannot be inserted.
Damage to the catalytic converter or the
vehicle m ay result if the following points
are not observed:
z If the engine misfires or runs roughly
after a cold start, the engine power has
reduced significantly or other unusual
operating problems occur that indicate a
fault in the ignition system, please
contact a workshop as quickly as
possible. Drive at a slower speed and
with less engine revs for a short time if
ne ce ssary.
z If unburned fuel enters the catalytic
converter, this may result in overheating
and irreparable damage to the catalytic
converter.
You should therefore avoid frequent cold
starts, unnecessarily long use of the
starter when setting off, running the tank
dry (an irregular fuel supply leads to
overhea ting) and starting the engine by
pushing or towing.
z If the control indicator for exhaust
emission Z flashes, lift your foot off the
accelerator until the indicator stops
fla shing and is steadily lit. Contact a
workshop immediately.

emissions - see page 27.
