fuel reserve GMC YUKON XL DENALI 2002 Owners Manual

4-41
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.
Recreational Vehicle Towing
Recreational vehicle towing means towing your
vehicle behind another vehicle
-- such as behind a
motorhome. The two most common types of
recreational vehicle towing are known as ªdinghy
towingº (towing your vehicle with all four wheels on the
ground) and ªdolly towingº (towing your vehicle with
two wheels on the ground and two wheels up on a
device known as a ªdollyº).
Your vehicle was not designed to be towed with any of
its wheels on the ground. If your vehicle must be towed,
see ªTowing Your Vehicleº in the Index.
NOTICE:
Towing your vehicle with all four wheels on the
ground will damage drivetrain components. And,
since your vehicle has all
-wheel drive, towing
with only two wheels on the ground will also
damage drivetrain components.
