overheating CADILLAC XLR 2009 1.G Owners Manual

Notice:Adding any electrical equipment to the
vehicle can damage it or keep other components
from working as they should. The repairs would not
be covered by the vehicle warranty. Do not use
equipment exceeding maximum amperage rating of
20 amperes. Check with your dealer/retailer before
adding electrical equipment.
When adding electrical equipment, be sure to follow the
installation instructions included with the equipment.
We recommend that you see a qualied technician or
your dealer/retailer for the proper installation of the
equipment.
Notice:Improper use of the power outlet can cause
damage not covered by the warranty. Do not hang
any type of accessory or accessory bracket from the
plug because the power outlets are designed for
accessory power plugs only.Ashtray(s) and Cigarette Lighter
The ashtray and cigarette lighter are located under a
lid in the front console to the right of the shift lever.
Press the left side of the lid and it will open
automatically.
To use the cigarette lighter, push it in all the way and
let go. When it is ready, it will pop back out by itself.
Notice:If papers, pins, or other ammable
items are put in the ashtray, hot cigarettes or other
smoking materials could ignite them and possibly
damage the vehicle. Never put ammable items
in the ashtray.
Notice:Holding a cigarette lighter in while it is
heating does not let the lighter back away from the
heating element when it is hot. Damage from
overheating can occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
As the pointer nears 260°F (125°C), your engine coolant
temperature is high. A message may display on the
Driver Information Center (DIC) depending on how high
the temperature is. SeeDIC Warnings and Messages
on page 3-60for more information.

(Temperature)
This message displays when the transmission uid in
the vehicle is too hot. Stop and allow the vehicle to idle

Engine Coolant
The cooling system in the vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in the vehicle for ve years or
150,000 miles (240 000 km), whichever occurs rst.
The following explains the cooling system and how to
check and add coolant when it is low. If there is a
problem with the engine overheating, seeEngine
Overheating on page 6-27.
What to Use
{CAUTION:
Adding only plain water to the cooling system can
be dangerous. Plain water, or some other liquid
such as alcohol, can boil before the proper coolant
mixture will. The vehicle’s coolant warning system
is set for the proper coolant mixture. With plain
water or the wrong mixture, the engine could get
too hot but you would not get the overheat
warning. The engine could catch re and you or
others could be burned. Use a 50/50 mixture of
clean, drinkable water and DEX-COOL
®coolant.Use a 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant. If using this mixture, nothing else
needs to be added. This mixture:
Gives freezing protection down to−34°F (−37°C),
outside temperature.
Gives boiling protection up to 265°F (129°C),
engine temperature.
Protects against rust and corrosion.
Will not damage aluminum parts.
Helps keep the proper engine temperature.
Notice:If an improper coolant mixture is used,
the engine could overheat and be badly damaged.
The repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and
other parts.
Notice:If extra inhibitors and/or additives are used
in the vehicle’s cooling system, the vehicle could
be damaged. Use only the proper mixture of
the engine coolant listed in this manual for the
cooling system. SeeRecommended Fluids and
Lubricants on page 7-11for more information.
6-23

If the LOW COOLANT message does not appear on the
Driver Information Center (DIC) after two minutes, the
coolant is at the proper ll 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. SeeEngine
Compartment Overview on page 6-12for 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). SeeDIC 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. SeeEngine 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.
SeeRoadside 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 re while driving
with no coolant, the vehicle can be badly damaged.
The costly repairs would not be covered by the
vehicle warranty. SeeOverheated Engine Protection
Operating Mode on page 6-29for information on
driving to a safe place in an emergency.

2. Push the release lever (B) to disengage the hook
and push the wiper arm (A) out of the blade (C).
3. Push the new wiper blade securely on the wiper arm
until you hear the release lever click into place.
Tires
Your new vehicle comes with high-quality tires
made by a leading tire manufacturer. If you ever
have questions about your tire warranty and where
to obtain service, see your vehicle warranty
booklet for details. For additional information refer
to the tire manufacturer.
{CAUTION:
Poorly maintained and improperly used tires
are dangerous.
Overloading your vehicle’s tires can
cause overheating as a result of too
much exing. You could have an air-out
and a serious accident. SeeLoading the
Vehicle on page 5-21.
Underinated tires pose the same danger
as overloaded tires. The resulting
accident could cause serious injury.
Check all tires frequently to maintain the
recommended pressure. Tire pressure
should be checked when your vehicle’s
tires are cold. SeeInflation - Tire
Pressure on page 6-54.
Overinated tires are more likely to be cut,
punctured, or broken by a sudden
impact — such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents. If the
tire’s tread is badly worn, or if your
vehicle’s tires have been damaged,
replace them.
