308 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
Your vehicle is equipped with an automatic
transmission. Consequently, the engine
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 safe­
ly. Refer to the manufacturer's specifications.
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 °C). 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 248, 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 coble
clomps in exactly the order described below!

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 309
Connect POSI TIVE(+ ) to POSITIVE (+ )
(red )
.. Open the red cover on the positive pole
¢fig. 260 .
1. Connect one end of the red positive cable
on the
jump sta rt bolt ¢ fig. 261 (D
(Bolts under red cover = "posit ive") of the
vehicle to be started ®·
2. Co nnect th e other end to the pos itive ter-
mina l@ of the booster battery @.
Connect NEGATIVE( -) to NEGATIVE(-)
( black )
3. Connect one end of the black negative ca­
ble to the negat ive termina l@ of the
booster b attery @.
4 . Connect the othe r end of the black nega­
tive cab le to the
jump start bolt@ (Bolts
with hex head= "negative") of the vehicle
to be started @.
Sta rting the engine
.,. Sta rt the e ngine of the veh icle with the
booster ba tte ry @ . Ru n the engine at a
moderate speed .
.. Start engine with discharged vehicle battery
® in the usual manner .
.. If the eng ine fails to start: do not keep the
starter crank ing fo r longer than 10 seconds.
Wa it for about 30 seco nds a nd the n try
again .
.,. With engine runni ng, remove jumper cab les
from both vehicles in the exa ct
reverse or­
de r .
.. Close the red cover on the posi tive po le .
T he battery is vented to the outside to p reven t
gases from en ter ing the veh icle inter ior. Make
s ur e that the jumper clamps a re well connect­
ed with their
metal ports in full contact with
the battery term inals.
.&_ WARNING
-To avoid serious personal injury and dam­
age to the ve hicle, heed all warnings and
i n structions of the jumper cable manufac-
-
turer . If in doubt, call for road service . IIJ>
