Cadillac 2009 XLR Automobile User Manual


 
If the LOW COOLANT message does not appear on the
Driver Information Center (DIC) after two minutes, the
coolant is at the proper fill level. If a LOW COOLANT
message does appear, repeat Steps 1 through 3 then
reinstall the pressure cap, or see your dealer/retailer.
If coolant is needed, add the proper DEX-COOL
®
coolant mixture at the coolant surge tank.
Notice: If the pressure cap is not tightly installed,
coolant loss and possible engine damage may occur.
Be sure the cap is properly and tightly secured.
The coolant surge tank pressure cap must be fully
installed on the coolant surge tank. See Engine
Compartment Overview on page 6-12 for more
information on location.
Engine Overheating
The vehicle has several indicators to warn of engine
overheating.
There is a COOLANT OVER TEMP message or an
ENGINE HOT, STOP ENGINE message displayed in the
Driver Information Center (DIC). See DIC Warnings
and Messages on page 3-60. You will also hear a chime.
There is also an engine coolant temperature gage on
the instrument panel cluster. See Engine Coolant
Temperature Gage on page 3-49.
You may decide not to lift the hood when this warning
appears, but instead get service help right away.
See Roadside Service on page 8-7.
If you do decide to lift the hood, make sure the vehicle
is parked on a level surface.
Then check to see if the engine cooling fans are
running. If the engine is overheating, both fans should
be running. If they are not, do not continue to run
the engine and have the vehicle serviced.
Notice: Engine damage from running the engine
without coolant is not covered by the warranty.
Notice: If the engine catches fire while driving
with no coolant, the vehicle can be badly damaged.
The costly repairs would not be covered by the
vehicle warranty. See Overheated Engine Protection
Operating Mode on page 6-29 for information on
driving to a safe place in an emergency.
