Normally, a battery should be charged at no
more than 10 percent of its rated capacity.
For example, a charging current of 4.5 amps
wou ld be used on a battery rated at 45 Ah.
Rated capacity of the battery in your veh icle is
listed on the battery housing .
The battery caps should

- Fast charging a battery is dangerous and
should only be attempted by a compe­
tent tech nician with the proper equip­
ment .
- Battery acid that may spill during charg­
ing should be washed off with a solution
of wa rm water and bak ing soda to neu­
tralize th e ac id .

Emergency situations
General
This chapter is intended for trained emer­
gency crews and working personnel who
have the necessary tools and equipment to
perform these operations.
Starting by pushing or
towing
(D Note
Vehicles with an automatic transmission
cannot be started by pushing or towing .
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another vehicle,
using a
pair of jumper cables to start the en­
gine.
Jumper cables
Use only jumper cables of sufficiently
largec ross section to safely carry the starter
current. Refer to the manufacturer's specifica­
tions.
Use only jumper cables which have
insulated
termina l clamps and are properly marked for
distinction :
plus(+) cable in most cases colored red
minus(-) cable
i n most cases colored black.
_& WARNING
Batteries contain electricity, ac id, and gas.
Any of these can cause very serious or fatal
injury. Follow the instructions below for
safe handling of your vehicle's battery.
- Always shield you r eyes and avoid lean­
ing over the battery whenever possible.
Emergency situations 231
-A discharged battery can already freeze
at temperatures just below 32 °F (0 °C).
Before connecting a jumper cable, the
frozen battery must be thawed com­
pletely, othe rwise 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 batter ies generate explosive gas­
es. Keep sparks, flame and lighted ciga­
rettes away from batteries.
- Do not try to jump start any veh icle w ith
a low ac id level in the battery.
- The voltage of the booster battery must
also have a 12-Volt rating. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged bat­
tery . Use of batteries of different voltage
or substantially different "Ah" rat ing
may cause an exp losion and personal in­
jury.
- Never charge a frozen battery. Gas trap­
ped in the ice may cause an explosion.
- Never charge o r use a battery that has
been frozen . The battery case may have
be weakened.
- Use of batter ies of different voltage or
substantially different capacity (Ah) rat ­
ing may cause an exp losion and injury .
The ca pa city (Ah) of the booster battery
should not be lower than that of the dis­
charged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢
page 172, Engine com­
partment.
(D Note
- App lying a higher voltage booster bat­
tery will cause expensive damage to sen­
sit ive electronic components, such as
control units, relays, rad io, etc .
- There must be no electrical contact be­
tween the vehicles as otherwise current
could already start to flow as soon as the
posit ive(+) terminals are connected. ..,. •
