2004 CADILLAC XLR coolant temperature

Notice:Holding the button in for longer than
15 seconds at a time will cause the battery to be
drained much sooner. This can also cause damage
to the starter motor. Wait 15 seconds between
each try to avoid draining your vehicle's battery or
damaging the starter.
2. If the engine does not start and no DIC message is
displayed, wait 15 seconds before trying again.
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.
Stopping Your Engine
Move the shift lever to PARK (P) and press the
OFF/ACCESSORY button. If the shifter is not in PARK
(P), the vehicle will go into ACCESSORY mode and
the DIC will display SHIFT TO PARK. Once the shifter
is moved to PARK (P), the vehicle will turn off.If the keyless access transmitter is not detected
while going to off, the DIC will display NO FOB, OFF
OR RUN.
See
DIC Warnings and Messages on page 3-57for
more information.
Engine Coolant Heater
Your vehicle may be equipped with an engine coolant
heater.
In very cold weather, 0ÉF (-18ÉC) 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 32ÉF (0ÉC), use of the coolant
heater is not required.
2-21

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord is located on the driver's side
of the engine compartment, in front of the engine
coolant surge tank.
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.

Notice:We recommend you use only ¯uid labeled
DEXRONž-III, because ¯uid with that label is
made especially for your automatic transmission.
Damage caused by ¯uid other than DEXRON
ž-III is
not covered by your new vehicle warranty.
Change both the ¯uid and ®lter every 50,000 miles
(80 000 km) if the vehicle is mainly driven under one of
these conditions:
·In heavy city traffic where the outside temperature
regularly reaches 90ÉF (32ÉC) or higher.
·In hilly or mountainous terrain.
·High performance operation.
If you do not use your vehicle under one of these
conditions, change the ¯uid and ®lter every
100,000 miles (166 000 km).
See
Scheduled Maintenance on page 6-4for the proper
service intervals for the transmission ¯uid and ®lter.
Engine Coolant
The cooling system in your vehicle is ®lled with
DEX-COOLžengine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs ®rst, if you add
only DEX-COOL
žextended life coolant.The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, see
Engine Overheating on
page 5-23.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
žcoolant will:
·Giving freezing protection down to-34É F-37É C.
·Give boiling protection up to 265É F (129É C).
·Protect against rust and corrosion.
·Help keep the proper engine temperature.
·Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOLžmay
cause premature engine, heater core or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at 30,000 miles (50 000 km)
or 24 months, whichever occurs ®rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
ž(silicate-free) coolant in your vehicle.

Coolant Surge Tank Pressure Cap
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.
See
Engine Compartment Overview on page 5-12for
information on location.
Engine Overheating
You will ®nd an COOLANT OVER TEMP message or
an ENGINE HOT, STOP ENGINE message displayed in
the Driver Information Center (DIC). 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 3-47.
Overheated Engine Protection
Operating Mode
This operating mode allows your vehicle to be driven to
a safe place in an emergency situation. If an overheated
engine condition exists and the DIC message ENGINE
HOT, STOP ENGINE is displayed, an overheat
protection mode which alternates ®ring groups of
cylinders helps prevent engine damage. In this mode,
you will notice a signi®cant loss in power and engine
performance. Driving extended miles (km) in the
overheat protection mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any
repair. The engine oil will be severely degraded.
Repair the cause of coolant loss, change the oil and
reset the oil life system. See
Engine Oil on
page 5-13.
