Starting and driving
131
• Have the car serviced regularly in accordance
with the service programme.
• Always be alert to any misfiring of the
engine (not running on all cylinders) and
any loss of power or performance. At the
first sign of a malfunction, reduce speed
and take the car to a workshop as soon as
possible. We recommend that you contact
an authorised Cadillac workshop.
• If the engine fails to start (in severe cold or
if the battery is flat), the car can be bump
started (manual gearbox only) or started
using jump leads to a donor battery. However,
as soon as you have started the
engine, it is important that it runs on all
cylinders. If it is misfiring, allow it to idle for
up to 5 minutes to give it time to settle and
run smoothly. If, after this time, the engine
still fails to run properly, switch off the
engine to avoid serious damage to the
catalytic converter. We recommend that
you contact an authorised Cadillac workshop
for advice.

• Never park the car in dry grass or on other
combustible material. The catalytic converter
gets very hot and could therefore
start a fire.
• Never drive off if the engine is misfiring.
• If you bump start the car when the engine
is already at normal working temperature,
the engine must start to run on all cylinders.
Abort bump starting if the engine
fails to start immediately.
Failure to strictly follow these instructions
can result in damage to the catalytic converter
and associated components, and
could represent a breach of the warranty
conditions.
NOTICE
If the car runs out of petrol, air may be
drawn in with the fuel, which, in turn, can
cause the catalytic converter to be damaged
by overheating.
WARNING
If the engine is being run with the car on a
rolling road or dynamometer, to ensure
adequate cooling, air must be blown into
the engine compartment and under the
car at a rate equivalent to the ram-air
effect that would obtain at the corresponding
road speed.
