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 ope rations.
Starting by pushing or
towing
Q;) Note
Vehicles with an automati c 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 veh icle,
using a
pair of jumper cables to start the en
g ine .
Jumper cables
Use only jumper cables of sufficiently large
cross section to carry the starter current safe
ly. Refer to the manufacturer's specifications.
Use only jumper cables with
insulated termi
na l clamps which are distinctly marked:
plus(+) cable in most cases colored red
minu s(-) cable
in most cases colored black .
A WARNING
Batteries contain electricity, ac id, and gas .
Any of these can cause very serious or fatal
inju ry. Follow the instructions below for
safe handling of your veh icle's battery.
- Always shield you r eyes and avoid lean
ing over the battery whenever possible.
- A discharged battery can freeze at tem
peratures just be low 32 °F (0 °C). Before connecting a
jumper cable, you must
thaw the frozen battery complete ly, oth
erwise 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 gas
es. Keep sparks, flame and lighted ciga
rettes away from batteries.
- Do not try to jump start any vehicle with a low ac id level in the battery.
- The vo ltage 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 d ifferent voltage
or substantially different "Ah" rating
may cause an exp losion and personal in
jury.
- Never charge a frozen batte ry. Gas trap
ped in the ice may cause an explosion.
- Never charge or 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 capacity (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 a ll
WARNINGS ¢

(D Note
-App lying a higher voltage booster bat
tery will cause expensive damage to sen
sitive electronic components, such as
control units, relays, radio, etc .
- Th ere must be no electrical contact be
tween the vehicles as otherwise current cou ld already start to f low as soon as the
positive(+) terminals are connected. .,.
