ECU CADILLAC ESCALADE ESV 2007 2.G Repair Manual

Acquaint yourself with the feel of handling and
braking with the added weight of the trailer. And
always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly
as responsive as your vehicle is by itself.
Before you start, check all trailer hitch parts and
attachments, safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer
has electric brakes, start your vehicle and
trailer moving and then apply the trailer brake
controller by hand to be sure the brakes are
working. This lets you check your electrical
connection at the same time.
During your trip, check occasionally to be sure
that the load is secure, and that the lamps and
any trailer brakes are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead
as you would when driving your vehicle without
a trailer. This can help you avoid situations
that require heavy braking and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a
good deal longer, you’ll need to go much farther
beyond the passed vehicle before you can
return to your lane.
Backing Up
Hold the bottom of the steering wheel with
one hand. Then, to move the trailer to the left, just
move that hand to the left. To move the trailer to the
right, move your hand to the right. Always back up
slowly and, if possible, have someone guide you.
Making Turns
Notice:Making very sharp turns while
trailering could cause the trailer to come in
contact with the vehicle. Your vehicle could
be damaged. Avoid making very sharp
turns while trailering.
When you’re turning with a trailer, make wider
turns than normal. Do this so your trailer
won’t strike soft shoulders, curbs, road signs,
trees or other objects. Avoid jerky or sudden
maneuvers. Signal well in advance.

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.
The coolant surge tank pressure cap must be fully
installed on the coolant surge tank. SeeEngine
Compartment Overview on page 406for more
information on location.

You will nd a coolant temperature gage on your
vehicle’s instrument panel. SeeEngine Coolant
Temperature Gage on page 238.
In addition, the messages ENGINE OVERHEATED
STOP ENGINE, ENGINE OVERHEATED IDLE
ENGINE, or ENGINE POWER IS REDUCED could
appear in the Driver Information Center (DIC) on
the instrument panel. SeeDIC Warnings and
Messages on page 250.
If Steam Is Coming From Your Engine
{CAUTION:
Steam from an overheated engine can
burn you badly, even if you just open the
hood. Stay away from the engine if you
see or hear steam coming from it. Just
turn it off and get everyone away from the
vehicle until it cools down. Wait until
there is no sign of steam or coolant
before you open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch re.
You or others could be badly burned.
Stop your engine if it overheats, and get
out of the vehicle until the engine is cool.

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your
tires as soon as possible and check wheel
alignment. Also check for damaged tires or wheels.
SeeWhen It Is Time for New Tires on page 469
andWheel Replacement on page 474for
more information.
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire. If it
moves, use the ratchet/wheel wrench to tighten the
cable. SeeChanging a Flat Tire on page 476.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The
rst rotation is the most important. SeeScheduled
Maintenance on page 521.

wrench counterclockwise until approximately
6 inches (15 cm) of cable is exposed.
6. Stand the wheel blocks on their shortest ends,
with the backs facing each other.
7. Place the bottom
edge of the jack (A)
on the wheel
blocks (B),
separating them so
that the jack is
balanced securely.

6. Raise the tire fully against the underside of
the vehicle by turning the wheel wrench
clockwise until you hear two clicks or feel it

pull (A), and then try to turn (B) the tire. If the
tire moves, use the wheel wrench to tighten
the cable.

sure to position the holes in the base of
the jack onto the pin in the mounting bracket.
5. Use the retaining bracket (C) to fasten the tool
bag (B) on the stud and turn the wing nut (D)
clockwise to secure.
6. Return the storage tray to its original stored
position.Spare Tire
Your vehicle, when new, had a fully-inated spare
tire. A spare tire may lose air over time, so check its
ination pressure regularly. SeeInation - Tire
Pressure on page 460andLoading Your Vehicle on
page 370for information regarding proper tire
ination and loading your vehicle. For instruction on
how to remove, install, or store a spare tire, see
Removing the Flat Tire and Installing the Spare Tire
on page 482andStoring a Flat or Spare Tire and
Tools on page 492.
After installing the spare tire on your vehicle, you
should stop as soon as possible and make
sure the spare is correctly inated. Have the
damaged or at road tire repaired or replaced as
soon as you can and installed back onto your
vehicle. This way, a spare tire will be available in
case you need it again.
Your vehicle may have a different size spare tire
than the road tires, those originally installed on your
vehicle. This spare tire was developed for use on
your vehicle, so it is all right to drive on it.
