284 Emergency situations
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
Q;) 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
large cross section to carry the starter current
safely. Refer to the manufacturer's specifica
ti ons.
Use only jumper cables with
insulated termi
nal 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
injury. Follow the instructions below for
safe handling of your vehicle's battery.
- Always shield your eyes and avoid lean
ing over the battery whenever possible. -
A discharged battery can freeze at tem
peratures just below
32 °F (0 °(). Before
connecting a jumper cable, you must
thaw the frozen battery completely, 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 acid 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" rating
may cause an explosion and personal in
jury.
- Never charge a frozen battery. 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 batteries of different voltage or
substantially different capacity (Ah) rat
ing may cause an explosion 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 all
WARNINGS¢
page 230, Engine com
partment.
@ Note
- Applying a higher voltage booster bat
tery will cause expensive damage to sen
sitive electronic components, such as
control units, relays, radio, etc.
- There must be no electrical contact be
tween the vehicles as otherwise current
could already start to flow as soon as the
positive(+) terminals are connected. ..,.
@ Tips
-The discharged battery must be properly
connected to the vehicle's electrical sys
tem. When jump start ing or charging the
battery, never connect the negative
ground cable to the battery negative
post because the battery manager sys
tem must be able to detect the battery's
state of cha rge . A lways connect the neg
ative g round cab le to the negative
gro und post o f the battery manage r con
trol uni t.
Use of jumper cables
Make sure to connect the jumper cobl e
clomps in exactly the order describ ed b elow!

The procedure described below for connecting
jumper cables is intended to provide a jump
start for your veh icle .
Vehicle with discharged batter y:
.. Turn off lights and accessories , move lever
of automatic transmission to
N (Neutral) or
P (Park) and set parking brake.
Emergenc y situ ation s 285
Connect POSI TIVE(+ ) to POSITIVE (+ )
(red )
.. Remove the cover above the jump start con
nection .
.. Open the red cover on the positive pole
¢fig. 230 .
1. Connect one end of the red positive cable
on the
jump sta rt bolt ¢ fig. 231 (D
(Bolts under red cover= "positive ") of the
vehicle to be star ted @.
2. Connect the othe r end to the pos itive ter -
mina l@ of the booster battery @.
Connect NEGATIVE (-) to NEGATIVE (-)
(black )
3. Connect one end of the b lack negative ca
ble to the nega tive te rmi na l@ of the
booster battery @.
4 . Connect the other end to the
jump start
bolt @
(Bolts with hex head = "negative")
of the vehicle to be started @.
Sta rting the engine
.. Start t he engine of the veh icle w ith the
booster battery @. Run the engine at a
moderate speed .
.. Start engine w ith d ischarged vehicle battery
® in the usual manner .
.. If the eng ine fails to start: do not keep the
starter crank ing for lo nger than 10 seconds .
Wait for about 30 seconds and the n try
aga in .
.,. With engi ne runni ng , remove j umper cab les
from both vehicles in the exact
reverse o r
der .
.. Close the red cover on the positive pole .
T he battery is vented to the o utside to p revent
gases from entering the veh icle in ter ior . Make
s ur e that the j umper clamps a re well connect
e d with their
metal ports in full contact with
the batte ry terminals.
A WARNING
To avoid serious personal injury and dam
age to the vehicle, heed all warnings and
instructions of the jumper cable manufac-
turer . If i n doubt, call for road service .
