9-4 Driving and Operating
Engine Coolant Heater The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below − 18°C (0°F). Vehicles
with an engine heater should be
plugged in at least four hours before
starting. An internal thermostat in
the plug-end of the cord may exist
which will prevent engine coolant
heater operation at temperatures
above − 18°C (0°F). Using the Engine Coolant
Heater 1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord. The cord is
secured to a wiring harness
between the engine and the
Hybrid Auxiliary Underhood
Fuse Block with a clip. Carefully
remove the wire tie which
secures the electrical cord.
Do not cut the electrical cord.
3. Plug the cord into a normal,
grounded 110-volt AC outlet.
{ WARNINGPlugging the cord into an
ungrounded outlet could cause
an electrical shock. Also, the
wrong kind of extension cord
could overheat and cause a fire.
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.

Vehicle Checks Doing Your Own
Service Work
{ WARNINGNever try to do your own service
on hybrid components. You can
be injured and the vehicle can be
damaged if you try to do your own
service work. Service and repair
of these hybrid components
should only be performed by a
trained service technician with the
proper knowledge and tools. { WARNINGYou can be injured and the
vehicle could be damaged if you
try to do service work on a vehicle
without knowing enough about it. .
Be sure you have sufficient
knowledge, experience,
the proper replacement
parts, and tools before
attempting any vehicle
maintenance task. .
Be sure to use the proper
nuts, bolts, and other
fasteners. Metric and
English fasteners can be
easily confused. If the wrong
fasteners are used, parts can
later break or fall off. You
could be hurt. If doing some of your own service
work, use the proper service
manual. It tells you much more
about how to service the vehicle
than this manual can. To order the
proper service manual, see “ Service
Publications Ordering Information ”
in the owner manual.
This vehicle has an airbag system.
Before attempting to do your own
service work, see “ Airbag System
Check ” in the owner manual.
Keep a record with all parts receipts
and list the mileage and the date of
any service work performed. See
“ Maintenance Records ” in the owner
manual.

Automatic Transmission
Fluid When to Check and Change
Automatic Transmission Fluid It is usually not necessary to
check the transmission fluid level.
The only reason for fluid loss is a
transmission leak or overheating
the transmission. If a small leak is
suspected, then use the following checking procedures to check the
fluid level. However, if there is a
large leak, then it may be necessary
to have the vehicle towed to a
dealer and have it repaired before
driving the vehicle further.
Notice: Use of the incorrect
automatic transmission fluid
may damage the vehicle, and the
damages may not be covered by
the vehicle warranty. Always use
the automatic transmission fluid
listed in Recommended Fluids
and Lubricants on page 11 ‑ 2 .
Change the fluid and filter at the
scheduled maintenance intervals.
See “ Scheduled Maintenance ” in
the owner manual. Be sure to use
the transmission fluid listed in
Recommended Fluids and
Lubricants on page 11 ‑ 2 .

Vehicle Care 10-13When to Change Lubricant
See “ Scheduled Maintenance ” in the
owner manual to determine how
often to change the lubricant.
What to Use
Refer to the Recommended Fluids
and Lubricants on page 11 ‑ 2 to
determine what kind of lubricant
to use.
Electrical System High Voltage Devices and
Wiring
{ WARNINGExposure to high voltage can
cause shock, burns, and even
death. The high voltage
components in the vehicle can
only be serviced by technicians
with special training.
High voltage components are
identified by labels. Do not
remove, open, take apart,
or modify these components.
High voltage cable or wiring has
orange covering. Do not probe,
tamper with, cut, or modify high
voltage cable or wiring. Fuses and Circuit
Breakers The wiring circuits in the vehicle
are protected from short circuits
by a combination of fuses, circuit
breakers and fusible thermal links.
This greatly reduces the chance of
fires caused by electrical problems.
Be sure you replace a bad fuse with
a new one of the identical size and
rating.
If you ever have a problem on the
road and do not have a spare fuse,
you can borrow one that has the
same amperage. Just pick some
feature of the vehicle that you can
get along without, like the radio or
cigarette lighter, and use its fuse,
if it is the correct amperage.
Replace it as soon as you can.
Black plate (14,1)Cadillac Escalade Hybrid - 2012
10-14 Vehicle Care The vehicle also has a special fuse
in the battery box for the 300-volt
batteries. If this fuse has failed and
needs to be replaced, the vehicle
will be disabled and you will need
to have the vehicle repaired by
your dealer. Do not attempt to
self-service this fuse.
Engine Compartment
Fuse Block Hybrid Auxiliary Engine
Compartment Fuse Block The hybrid auxiliary engine
compartment fuse block is located
in the engine compartment near the
front of the vehicle. Lift the cover for
access to the fuse/relay block. See
