Getting Started
Most of the necessary maintenance
and minor repair that an automobile will
need can be done with ordinary tools.
Below is some important information on
how to work safely, a discussion of
what tools will be needed and how to
use them.
Safety
Although an automobile presents many
hazards, common sense and good
equipment can help ensure safety.
Many accidents happen because of
carelessness. Pay attention and stick
to safety rules in this manual.
Lifting the car
The proper jacking points should be
used to raise the car safely and avoid
damage. The jack supplied with the car
can only be used at the four side
points (arrows)—just behind the front
wheels or just in front of the rear
wheels.
WARNING!
Never work under a lifted car
unless it is solidly supported on
jack stands that are intended for
that purpose.
When raising the car using a
floor jack or a hydraulic lift,
carefully position the jack pad to
prevent damaging the car body.
Plastic pads are provided for
this purpose by the
manufacturer at the jacking
points.
Watch the jack closely. Make
sure it stays stable and does not
shift or tilt. As the car is raised,
it may roll slightly and the jack
may shift.
Raising car safely
-
Park car on flat, level surface.
-
If changing a tire, loosen lug bolts
before rasing car. See
Changing a tire
.
Place jack into position. Make sure jack
is resting on flat, solid ground. Use a
board or other support to provide a firm
surface for the jack, if necessary
-
Raise car slowly while constantly
checking position of jack and car.
-
Once car is raised, block wheel
that is opposite and farthest from
jack to prevent car from
unexpectedly rolling.
WARNING!
Do not rely on the transmission
or the emergency brake to keep
the car from rolling. They are
not a substitute for positively
blocking the opposite wheel.
Never work under a car that is
supported only by a jack. Use
jack stands that are designed to
support the car. See
Tools
.
Working under car safely
-
Disconnect negative (–) cable from
battery so that no one can start
car. Let others know what you will
be doing.
CAUTION!
Prior to disconnecting the battery,
read the battery disconnection
cautions given at the front of this
manual on page viii.
-
Raise car slowly as described
above.
-
Use at least two jack stands to
support car. Use jack stands
designed for the purpose of
supporting a car. For more
information on jack stands, see
Tools
.
WARNING!
A jack is a temporary lifting
device and should not be used
alone to support the car while
you are under it.
Do not use wood, concrete
blocks, or bricks to support a
car. Wood may split. Blocks or
bricks, while strong, are not
designed for that kind of load,
and may break or collapse.
-
Place jack stands on firm, solid
surface. If necessary, use a flat
board or similar solid object to
provide a firm footing.
-
Lower car slowly until its weight is
fully supported by jack stands.
Watch to make sure that the jack
stands do not tip or lean as the
car settles on them.
-
Observe all jacking precautions
again when raising car to remove
jack stands.
