coolant temperature CADILLAC CTS 2007 1.G Owners Manual

To prevent starter-motor gear damage, this
system also prevents cranking if the engine is
already running. The engine cranking can
be stopped by turning the ignition switch to the
ACCESSORY or OFF position.
2. If your engine will not start, or starts but then
stops, it could be ooded with too much
gasoline. Try pushing your accelerator pedal
all the way to the oor and holding it there
as you turn the key to START. If the vehicle
starts briey but then stops again, do the
same thing.
Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with
your dealer. If you do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.Engine Coolant Heater
Your vehicle may have an engine coolant heater.
In very cold weather, 0°F (−18°C) or colder,
the engine coolant heater can help. You will get
easier starting and better fuel economy during
engine warm-up.
Usually, the coolant heater should be plugged in
a minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C), use of
the coolant heater is not required. Your vehicle
may also have an internal thermostat in the
plug end of the cord. This will prevent operation of
the engine coolant heater when the temperature
is at or above 0°F (−18°C) as noted on the cord.
120

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. For the 2.8L V6 and the 3.6L V6
engines, the cord is located in the engine
compartment on the passenger’s side of the
vehicle in front of the fuse block. For the
6.0L V8 engine, the cord is located in
the engine compartment on the driver’s side
of the vehicle near the inner fender and above
the strut.
Remove the plastic cap to access the plug.
3. Plug it into a normal, grounded 110-volt AC
outlet.{CAUTION:
Plugging the cord into an ungrounded
outlet could cause an electrical shock.
Also, the wrong kind of extension cord
could overheat and cause a re. You
could be seriously injured. Plug the cord
into a properly grounded three-prong
110-volt AC outlet. If the cord will not
reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it
away from moving engine parts. If you do
not, it could be damaged.
How long should you keep the coolant heater
plugged in? The answer depends on the outside
temperature, the kind of oil you have, and
some other things. Instead of trying to list
everything here, we ask that you contact your
dealer in the area where you will be parking your
vehicle. The dealer can give you the best
advice for that particular area.
