Starting with jumper
cables
If necessary, the engine con be started by con-
necting it to the battery of another vehicle.
If the engine should fail to start because of a dis-
charged or weak battery, the battery can be con-
nected to the battery of
another
vehicle, using a
pair of j umper cables to start the engine.
Jumper cables
Use
only
jumper cables of sufficiently large cross
section to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated
term inal
clamps which are distinctly marked:
plus (+) cable in most cases colored red
minus (-) cable in most cases colored black.
A
WARNING
_ ,
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal in·
jury. Follow the instructions below for safe
handling of your vehicle's battery.
- Always shield your eyes and avoid leaning
over the battery whenever possible.
- A discharged battery can freeze at tempera-
tures just below 32 °F (0 °C). Before con-
necting a jumper cable, you must thaw the
288
frozen battery completely, otherwise it
could explode.
- Do not allow battery acid to contact eyes or
skin. Flush any contacted area with water
immediately.
- Improper use of a booster battery to start a
vehicle may cause an explosion.
- Vehicle batteries generate explosive gases.
Keep sparks, flame and lighted cigarettes
away from batteries.
- Do not t ry to jump start any vehicle with a
low acid level in the battery.
- The voltage of t he booster battery must also
have a 12-volt rating. The capacity (Ah) of
the booster battery s hould not be lower
than that of the discharged battery. Use of
batteries of different voltage or substantial-
ly different "Ah" rating may cause an explo-
sion and personal injury.
- Never charge a frozen battery. Gas trapped
in the ice may cause an explosion.
- Never charge or use a battery that has been
frozen. The battery case may have be weak-
ened.
- Use of batteries of different voltage or sub-
stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all

CD
Note
- Applying a higher voltage booster battery
wi ll cause expensive damage to sensitive
electronic
components, such as control
units, relays, radio, etc.
- There must be no electrical contact between
the vehicles as otherwise current could al-
ready start to flow as soon as the positive
(+)terminals are connected.
Tips
The discharged battery must be properly con-
nected to the vehicle's electrical system.
