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 .
