Hummer H3T Automobile User Manual


 
Run the engine for short periods
only as needed to keep warm,
but be careful.
To save fuel, run the engine for
only short periods as needed to
warm the vehicle and then shut the
engine off and close the window
most of the way to save heat.
Repeat this until help arrives
but only when you feel really
uncomfortable from the cold. Moving
about to keep warm also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine
runs faster than the idle speed. This
keeps the battery charged to
restart the vehicle and to signal for
help with the headlamps. Do
this as little as possible to save fuel.
If Your Vehicle is
Stuck in Sand, Mud,
Ice, or Snow
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
See Rocking Your Vehicle to Get It
Out on page 4-34.
If the vehicle has a traction system,
it can often help to free a stuck
vehicle. Refer to the vehicle’s
traction system in the Index. If stuck
too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method.
{ CAUTION
If you let your vehicle’s tires spin
at high speed, they can explode,
and you or others could be
injured. The vehicle can overheat,
causing an engine compartment
fire or other damage. Spin the
wheels as little as possible and
avoid going above 35 mph
(55 km/h) as shown on the
speedometer.
For information about using tire
chains on the vehicle, see Tire
Chains on page 5-65.
