Driving in hot climates

Always check the coolant level before
starting a journey. When the engine is cold,
the coolant level must be on or just above
the KALT/COLD mark (boundary between
the upper and lower sections of the tank).
At the end of a journey, allow the engine to
idle for 2–3 minutes before switching it off.
If the needle on the temperature gauge
enters the red zone, the following message
will be shown on the DIC:
Hot engine. Make a
safe stop. Idle engine.
1 Stop the car but do not switch off the
engine. Do not remove the cap on the
cooling system expansion tank, even if
the tank is empty. The engine tempera-
ture should decrease. If the temperature
continues to rise with the engine idling,
the engine must be switched off.
2 If the engine is idling and the needle on
the temperature gauge falls, wait until a
normal temperature is shown (about in
the middle of the scale) before switching
off the engine. If the coolant needs to be
topped up, carefully unscrew the
expansion tank cap.
Fill as required with a mixture of 50 %
antifreeze and 50 % clean water. Use an
antifreeze approved by Cadillac.
WARNING
• Exercise care when opening the
bonnet if the engine is overheated.
Never remove the expansion tank cap
completely when the engine is hot.
• The cooling system is pressurised - hot
coolant and vapour can escape. These
can cause injury to your eyes and
burns. Open the cap slowly to release
the pressure before removing it.
3 Have the car's cooling system checked
at a workshop. We recommend that you
contact an authorised Cadillac work-
shop.
Cars with diesel engine: The engine
has a protective function that prevents it
from overheating. The engine output is
reduced when the engine temperature is
so high that the needle enters the red
zone.
