2009 CADILLAC ESCALADE ESV heating

Rear Window Defogger The rear window defogger uses a warming grid to
remove fog from the rear window.
< (Rear Window Defogger): Press to turn the rear
window defogger on or off. It automatically turns off after
it has been activated. The defogger can also be turned off
by turning off the engine. Do not drive the vehicle until all
the windows are clear.
Notice: Do not use a razor blade or sharp object
to clear the inside rear window. Do not adhere
anything to the defogger grid lines in the rear glass.
These actions may damage the rear defogger.
Repairs would not be covered by your warranty.
Heated Mirrors: For vehicles with heated outside
rearview mirrors, the mirrors heat to help clear fog or
frost from the surface of the mirror when the rear window
defog button is pressed. See Outside Heated Mirrors
on page 2-42 .
Heated or Cooled Seats: For vehicles with heated
seats or heated and cooled seats, see Heated Seats on
page 1-5 or Heated and Cooled Seats on page 1-6 .Outlet Adjustment Use the air outlets located in the center and on the side
of the instrument panel to direct the airow.
Operation Tips
Keep the hood and front air inlets free of ice, snow,
or any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of the windows.
When you enter a vehicle in cold weather, press
the fan up button to the maximum fan level before
driving. This helps clear the intake ducts of snow
and moisture, and reduces the chance of fogging
the inside of the window.
Keep the air path under the front seats clear of
objects. This helps air to circulate throughout the
vehicle.
Adding outside equipment to the front of the
vehicle, such as hood-air deectors, may affect
the performance of the heating and air conditioning
system. Check with your dealer/retailer before
adding equipment to the outside of the vehicle.

Driving On Grades Reduce speed and shift to a lower gear before starting
down a long or steep downgrade. If the transmission is
not shifted down, the brakes might have to be used so
much that they would get hot and no longer work well.
Vehicles can tow in D (Drive). Shift the transmission to
a lower gear if the transmission shifts too often under
heavy loads and/or hilly conditions.
The tow/haul mode may be used if the transmission
shifts too often. See Tow/Haul Mode Light on page 3-46 .
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a lower
temperature than at normal altitudes. If the engine is
turned off immediately after towing at high altitude on
steep uphill grades, the vehicle may show signs similar to
engine overheating. To avoid this, let the engine run while
parked, preferably on level ground, with the transmission
in P (Park) for a few minutes before turning the engine
off. If the overheat warning comes on, see Engine
Overheating on page 6-30 . Parking on Hills
{ CAUTION: Parking the vehicle on a hill with the trailer
attached can be dangerous. If something goes
wrong, the rig could start to move. People can be
injured, and both the vehicle and the trailer can be
damaged. When possible, always park the rig on a
at surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift into P (Park)
yet. Turn the wheels into the curb if facing downhill
or into traffic if facing uphill.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking
brake and shift into P (Park).
5. Release the brake pedal.
