light CADILLAC ESCALADE EXT 2004 2.G Owners Manual

Winter DrivingHere are some tips for winter driving:
·Have your vehicle in good shape for winter.
·You may want to put winter emergency supplies in
your vehicle.
Include an ice scraper, a small brush or broom, a
supply of windshield washer ¯uid, a rag, some winter
outer clothing, a small shovel, a ¯ashlight, a red
cloth and a couple of re¯ective warning triangles. And, if
you will be driving under severe conditions, include a
small bag of sand, a piece of old carpet or a couple of
burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.

{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You can not see it
or smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow does
not collect there.
Open a window just a little on the side of the
vehicle that is away from the wind. This will
help keep CO out.Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine
again and repeat this only when you feel really
uncomfortable from the cold. But do it as little as
possible. Preserve the fuel as long as you can. To help
keep warm, you can get out of the vehicle and do
some fairly vigorous exercises every half hour or so until
help comes.

If You Are Stuck: In Sand, Mud, Ice
or Snow
In order to free your vehicle when it is stuck, you will
need to spin the wheels, but you do not want to
spin your wheels too fast. The method known as
ªrockingº can help you get out when you are stuck, but
you must use caution.
{CAUTION:
If you let your tires spin at high speed, they
can explode, and you or others could be
injured. And, the transmission or other parts of
the vehicle can overheat. That could cause an
engine compartment ®re or other damage.
When you are stuck, spin the wheels as little
as possible. Do not spin the wheels above
35 mph (55 km/h) as shown on the
speedometer.
Notice:Spinning your wheels can destroy parts of
your vehicle as well as the tires. If you spin the
wheels too fast while shifting your transmission
back and forth, you can destroy your transmission.
For information about using tire chains on your
vehicle, see
Tire Chains on page 5-81.
Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and right. That will
clear the area around your front wheels. If your vehicle
has the Stabilitrak
žSystem, turn the system off by
pressing the Stabilitrakžbutton so that the STABILITY
SYS DISABLED message and the traction off light
are illuminated on the instrument panel cluster. Then
shift back and forth between REVERSE (R) and a
forward gear, spinning the wheels as little as possible.
Release the accelerator pedal while you shift, and press
lightly on the accelerator pedal when the transmission
is in gear. By slowly spinning your wheels in the forward
and reverse directions, you will cause a rocking
motion that may free your vehicle. If that does not get
you out after a few tries, you may need to be towed out.
Or, you can use your recovery hooks if your vehicle
has them. If you do need to be towed out, see
Towing
Your Vehicle on page 4-46.
4-44

Press the button at the end of the shift lever to
enable/disable the tow/haul mode.A light on the instrument
panel will illuminate to
indicate that tow/haul
mode has been selected.
The vehicle will automatically turn off tow/haul every
time it is started.
Operating the vehicle in tow/haul when lightly loaded or
with no trailer at all will not cause damage. However,
there is no bene®t to the selection of tow/haul when the
vehicle is unloaded. Such a selection when unloaded
may result in unpleasant engine and transmission driving
characteristics and reduced fuel economy. Tow/haul
is recommended only when pulling a heavy trailer or a
large or heavy load.

CAUTION: (Continued)
·
Be sure to use the proper nuts, bolts and
other fasteners. ªEnglishº and ªmetricº
fasteners can be easily confused. If you
use the wrong fasteners, parts can later
break or fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the air¯ow around it. This may cause wind
noise and affect windshield washer performance. Check
with your dealer before adding equipment to the
outside of your vehicle.
Fuel
Use of the recommended fuel is an important part of the
proper maintenance of your vehicle.
Gasoline Octane
Use premium unleaded gasoline with a posted octane of
91 or higher for best performance. You may also use
middle grade or regular unleaded gasoline rated at
87 octane or higher, but your vehicle's acceleration may
be slightly reduced. If the octane is less than 87, you
may get a heavy knocking noise when you drive. If this
occurs, use a gasoline rated at 87 octane or higher
as soon as possible. Otherwise, you might damage your
engine.

CAUTION: (Continued)
Keep sparks, ¯ames and smoking materials
away from fuel. Do not leave the fuel pump
unattended when refueling your vehicle Ð this
is against the law in some places. Keep
children away from the fuel pump; never let
children pump fuel.
The fuel cap is located behind a hinged door on the
driver's side of the vehicle.
To remove the fuel cap,
turn it slowly to the left
(counterclockwise). It will
require more effort to turn
the fuel cap on the last turn
as you loosen it.
While refueling, hang
the fuel cap by the tether
using the hook located
on the inside of the
®ller door.
{CAUTION:
If a ®re starts while you are refueling, do not
remove the nozzle. Shut off the ¯ow of fuel by
shutting off the pump or by notifying the
station attendant. Leave the area immediately.
Be careful not to spill fuel. Don't top off or over®ll your
tank and wait a few seconds after you've ®nished
pumping before you remove the nozzle. Clean any spilled
fuel from painted surfaces as soon as possible. See
Cleaning the Outside of Your Vehicle on page 5-105.
When you put the fuel cap back on, turn it to the right
(clockwise) until you hear a clicking sound. It will require
more effort to turn the fuel cap on the last turn as you
tighten it. Make sure you fully install the cap. The
diagnostic system can determine if the fuel cap has
been left off or improperly installed. this would allow fuel
to evaporate into the atmosphere. See
Malfunction
Indicator Lamp on page 3-44.
Notice:If you need a new fuel cap, be sure to get
the right type. Your dealer can get one for you. If you
get the wrong type, it may not ®t properly. This may
cause your malfunction indicator lamp to light and
may damage your fuel tank and emissions system.
See
Malfunction Indicator Lamp on page 3-44.

How to Inspect
Vehicles with an Air Filter Restriction
Indicator
Locate the air ®lter restriction indicator on the engine air
cleaner/®lter cover. When the indicator turns black or
is in the red/orange ªchangeº zone, replace the ®lter and
reset the indicator. See the steps following to replace
the engine air cleaner/®lter and to reset the air ®lter
restriction indicator.
Vehicles without an Air Filter Restriction
Indicator
To inspect the air cleaner/®lter, remove the engine air
cleaner/®lter from the vehicle using the steps following.
When you have the engine air cleaner/®lter removed,
lightly shake it to release loose dust and dirt. If the
engine air cleaner/®lter remains caked with dirt, a new
one is required.
Replacing the Engine Air Cleaner/Filter
and Resetting the Air Filter Restriction
Indicator
1. Locate the air cleaner/®lter assembly on the front
corner of the engine compartment on the
passenger's side of the vehicle.
2. Loosen the screws on the cover of the housing and
lift up the cover.

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 5-26.A 50/50 mixture of clean, drinkable water and
DEX-COOL
žcoolant will:
·Give freezing protection down to-34ÉF (-37ÉC).
·Give boiling protection up to 265ÉF (129ÉC).
·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.
