To Use The Engine Coolant Heater; Automatic Transmission Operation - GMC 1999 Jimmy Owner's Manual

To Use the Engine Coolant Heater

1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is located on the driver's side of the engine
compartment, behind the underhood fuse block.
3. Plug it into a normal, grounded 110
CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three
-
110 volt AC outlet. If the cord won't reach, use a
- -
heavy duty three prong extension cord rated for
at least 15 amps.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it away
from moving engine parts. If you don't, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

Automatic Transmission Operation

Your automatic transmission may have a shift lever
located on the console between the seats or on the
steering column.
There are several different positions for your shift lever.
If your vehicle is equipped with a column shift lever, it
features an electronic shift position indicator within the
instrument cluster. This display must be powered anytime the
-
prong
shift lever is capable of being moved out of PARK (P). This
means that if your key is in OFF, but not locked, there will be
a small current drain on your battery which could discharge
your battery over a period of time. If you need to leave your
key in the ignition in OFF for an extended period, it is
recommended that you disconnect the battery cable from
the battery to prevent discharging your battery.
PARK (P): This locks your rear wheels. It's the best
position to use when you start your engine because your
vehicle can't move easily.
