Charging of battery
Starting the engine requires a well charged battery.
11-Al way s read and heed all WARNING S be­
low¢
A and ¢ A in Working on the bat­
tery on page 177.
11-Switch off the ignit ion and all electrical con­
sumers.
11-Make sure the area is well vent ilated when
you charge the bat tery.
11-Connect charger cables. ALWAY S co nnect
charge r cables POSITI VE
G) to POSITIVE
G) ; NEGATIVE Qto NEGA TIV E Q .
11-Switch on the charger.
11-Turn off the charger¢ &_.
11-Disconnect the charger cables.
11-Connect both battery cables to the battery if
necessary -
first plus, then m inus.
When charging at
low voltages (e.g. with a
trickle charg er), the battery cables do not
h ave to be d isconnected first. Before charging
at
high voltages, i.e. " fas t charging ", you
must disconnect both cables. In e ithe r case,
follow the instru ctions from the man ufactu rer
of the charger .
Fastcharging a battery is
dan gerou s¢ & in
Working on the battery on page 177.
It r e­
q ui res specia l charg ing equipment and the
know ledge to go with it. We recommend hav­
ing your battery fast charged on ly by a quali­
f ied workshop .
A discharged battery can
freeze at tempera ­
tures of on ly 32 °F (0 °C). A llow a frozen bat­
tery to thaw completely befo re attempting to
charge it¢ & . However, we recommend not
using a thawed battery again because the bat­
tery cas ing can be cracked due to ice forma­
tion and can leak battery acid.
Do not open the battery caps when charging
the battery.
A WARNING
-
Charging a battery can be dangerous.
Checkin g and fillin g 179
-Never charge a frozen battery. It may ex­
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out first.
- Do not reuse batteries wh ich were fro­
zen. The battery housing may have
cracked and weakened when the battery
froze.
- Charge the battery in a well ventilated
area. Keep away from open flame or elec­
trical spark. Do not smoke. Hydrogen gas
generated by the battery is explos ive.
- To reduce the danger of explosion, never
connect or d isconnect c harger cab les
while the charger is ope rat ing.
- Fast cha rging a batte ry is dangerous and
should only be attempted by a compe­
tent techn ic ian with the prope r equip­
men t.
- Battery acid that may spi ll dur ing cha rg­
i n g should be washed off wi th a solu tion
of wa rm w ater and baking soda to neu­
trali ze the ac id.
(D Note
Neve r use a fast cha rg er as a boost er to
star t the engi ne. This w ill ser iously dam­
age sens it ive e lectronic componen ts, su ch
as cont ro l units, re lays, radio, etc., as well
as the batte ry charger.
(D Tips
T he vehicle ba tte ry mu st not be charged
wi th a standa rd small charger that plugs

Clean water should be used when filling up . If
possible, use soft water to prevent scal ing on
the washer jets . Always add a glass cleaner
solutio n (with frost p rotection in the winter) .

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
g ine.
Jumper cables
Use only jumper cables of sufficiently
largecross 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
in most cases colored black.
_& 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 you r eyes and avoid lean­
ing over the battery whenever possible.
Emergency situations 21 7
-A discharged battery can already freeze
at temperatures just below 32 °F (0 °C).
Before connect ing a jumper cable, the
frozen battery must be thawed com­
pletely, otherwise 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 c iga­
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 diff erent 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 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 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
c::;,page 165, Working in the
engine compartment.
(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. ..,. •
