Driving with a hot engine cooling system
could damage your vehicle. If the tempera-
ture gauge reads “H” pull over and stop the
vehicle. Idle the vehicle with the air condi -
tioner turned off until the pointer drops back
into the normal range. If the pointer remains
on the “H”, turn the engine off immediately
and call an authorized dealer for service.

contact with your exhaust system. Do not
park or operate your vehicle in areas where
your exhaust system can contact anything
that can burn.
CAUTION!
The engine may be switched off even if the
warning light is on: repeated interruptions of
the regeneration process could cause an
early deterioration of engine oil. For this rea -
son it is always advisable to wait for the sym -
bol to go off before turning off the engine,
following the instructions above. Do not com -
plete the DPF regeneration process when the
vehicle is stopped.

IF ENGINE FAILS TO START
If the engine fails to start after you have
followed the “Normal Starting” or “Extreme Cold
Weather” procedure, it may be flooded. Push
the accelerator pedal all the way to the floor and
hold it there. Crank the engine for no more than
15 seconds. This should clear any excess fuel in
case the engine is flooded. Leave the ignition in
the RUN position, release the accelerator pedal
and repeat the “Normal Starting” procedure.
AFTER STARTING
The idle speed is controlled automatically and
will decrease as the engine warms up.
