ecu CADILLAC ESCALADE ESV 2008 Workshop Manual

When rotating your vehicle’s tires, always use the
correct rotation pattern shown here.
Do not include the spare tire in the tire rotation.
After the tires have been rotated, adjust the
front and rear ination pressures as shown
on the Tire and Loading Information label.
See Inflation - Tire Pressure on page 5-62
and Loading Your Vehicle on page 4-35 .
Reset the Tire Pressure Monitor System.
See Tire Pressure Monitor Operation on
page 5-65 . Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specifications on page 5-115 .
{ CAUTION: Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if needed, to get all the rust or dirt
off. See Changing a Flat Tire on page 5-79 .
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire. If it
moves, tighten the cable. See Storing a Flat or
Spare Tire and Tools on page 5-94 .

rotate the tires. See Tire Inspection and Rotation on
page 5-69 . At Least Once a Year Starter Switch Check
