fully opening the hood .
' Working in the engine compartment
Be especially careful whenever you work in
the engine compartment.
Whenever you must perform any work in the
engine compartment, for example checking
and filling different fluids, there is a risk of injury, burns and accidents. To prevent per­
sonal injury always observe the following
WARNINGS. The engine compartment of any
vehicle is a hazardous area
~ ,&. .
A WARNING
To help avoid injury, before you check any­
thing under the hood:
- Turn off the engine.
- Switch off the ignition .
- Apply the parking brake.
- Move selector lever to "P" (Park) .
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood.
- Keep children away from the engine com­
partment.
- Never spill fluids on hot engine compo­
nents . They can cause a fire .
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly .
- Never open the coolant reservoir cap
when the engine is still warm . The cool­
ant system is pressurized and hot cool­
ant could spray out.
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir.
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:

-Always disconnect the battery.
- Never smoke or work near heaters or open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch :
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
- First, fully apply the parking brake,
move selector lever to "P" (Park).
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts. Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and
chemical ha zards c:::> & .

246 Checking and filling
Battery charging
Starting the engine requires a well charged
battery.
Fig . 202 Engine co mpartme nt: connectors fo r a charg ­
er and jump sta rt cables
Always read and heed all WARNINGS below
c:> A and c:> A in Working on the battery on
page 244 .
.,. Switch off the ignition and all electrical con­
sumers .
.,. Make sure the area is well ventilated when
you charge the battery .
.,. Open the engine hood
r:::.> page 232 .
.,. Remove the cover© by press ing on the ar­
row
c:>fig . 202.
.,. Open the cover @on the positive term inal.
.,. Connect the charger connectors according
to the instructions to the
jump start bolts.
(Bolts under the red cover= "positive" , Bolts
with hex head = "negative").
.,. Only now plug the mains lead for the charg­
ing equipment into the wall outlet and turn
it on
r:::.> &_ .
.,. Make sure the charging rate i s not over
30 amps/14.8 Volt.
.,. When the battery is fully charged: Turn the
charging equipment off and remove the
mai ns lead from the wall outlet.
.,. Now
remove the clamps for the charging
equipment.
.. Close the red cover on the posit ive pole .
.,. Close the hood
c:> page 233 .
A discharged battery can freeze at tempera­
tures of only 32 F
0 (0 °C). Allow a frozen bat­
tery to thaw completely before attempting to
charge it
r:::.> &. . However , we recommend not
using a thawed battery again because the bat -tery casing can be cracked due to ice forma
­
tion and can leak battery acid.
Battery charging (Maximum charging rate
of 30 amps/14.8 Volt)
When charging at low voltages (e.g. with a
trickle charger), the battery cables do not
have to be disconnected f irst. The battery
caps should
not be opened when charging a
battery.
It i s not necessary to remove the battery from
the luggage compartment, and it is also not
necessary to disconnect the cables.
Fast charging the battery (charging rate
above 14 .8 Volts )
For technical reasons do not use a battery
charger that uses voltage greater than 14.8
Volts to charge your vehicle's battery .
A WARNING
Charging a battery can be dangerous.
- Always follow the operating instructions
provided by the battery charger manu­
facturer when charg ing your battery .
- 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
tr ica l spar k. Do not smoke. Hydrogen gas
generated by the battery is explos ive .
- To reduce the danger of explosion,
never
connect or disconnect charger cables
while the charger is operating .
- Fast charging a battery is dangerous and
should only be attempted by a compe­
tent technician with the proper equip­
ment .
- Battery acid that may spill dur ing charg­
ing should be washed off with a solution
of warm water and baking soda to neu­
tralize the acid.
