-Never open the vehicle battery. Do not try to
change the battery electro lyte level. Other­
wise explosive gas will escape from the bat­
tery and increase the r isk of an explos ion .
(D Tips
If your vehicle is not driven for several weeks
in very cold temperatures, remove the battery
and store it in a place where it will not freeze.
This prevents the battery from being dam­
aged and needing to be replaced .
Working on the battery
Be especially careful when working on or near
the battery .
The battery (12 V) is located in the engine com­
partment.
Always heed the
safety warnings, when working
on the vehicle battery or the vehicle electrical
system to prevent injury.
The following WARNINGS are very important
when working on the battery:
Always heed the following WARNING SYM-
BOLS and safety precautions when working on
the battery.
®
Always wear eye protection.
&
Battery acid contains sulfuric acid. Al-
ways wear gloves and eye protection.
@
No
- sparks
- flames
- smoking.
A
When a battery is charged, it produces
hydrogen gas which is explosive and
.
could cause personal injury .
®
Always keep the battery well out of
reach of children.
A WARNING
Whenever working on the battery or on the
electrical system, there is the risk of injury,
-
Checking and Filling
accident and even fire . Read and heed the fol­
low ing WARNINGS:
- Always wear eye protection. Do not let bat­
tery acid or any lead particles get on your
skin or clothing. Shield your eyes. Explosive
gases can cause blindness or other injury.
- Battery acid contains sulfur ic acid. Sulfuric
acid can cause blindness and severe burns.
- Always wea r gloves and eye protection. Do
not tilt the battery because acid could lea k
out of the ventilation openings.
- If you get battery acid in yo ur eyes or on
you r skin, immed iate ly r inse with cold wa­
ter for severa l min utes and get medical at­
tent ion .
- If you shou ld ingest any battery acid, seek
medica l attention immediate ly.
- Do not expose the battery to an open flame,
electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and nega-
tive cables.
- When working on the battery, be sure not to
short-circuit the termina ls with tools or oth­
er metal objects. This would cause the bat­
tery to heat up very quickly, which could
lead to damage or exp losion and personal
inj ury.
- When a battery is charged, it produces hy­
drogen gas which is explosive and could
cause persona l injury.
- Always keep the battery well out of the
reach of children.
- Before work is done on the e lectrical sys­
tem, disconnect the negative ground cable.
- Before performing any work on the electri­
cal system, switch off the engine and igni­
tion as well as any electrical equipment. The
negat ive cab le on the battery must be dis­
connected. If you are just going to replace a
light bulb, then it is enough to switch off
the lights.
- Before disconnecting the battery, switch off
the anti-theft a larm system! Otherwise you
will set off the alarm .
- When disconnecting the battery, first dis­
connect the negat ive cable and then the
positive cable.

Emergency situations
Emergency situations
General
This chapter is intended for trained emergency crews and working personnel who have the nec­
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
CD Note
Vehicles with an automatic transmission can­
not be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine con be started by con­
necting it to the battery of another vehicle .
If the engine should fail to start because of a dis­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
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 in­
jury. Follow the instructions below for safe hand Ling of your vehicle's battery .
-Always shield your eyes and avoid leaning
over the battery whenever possible.
-A discharged battery can freeze at tempera­
tures just below 32 °F (0 °C). Before con­
necting a jumper cable, you must thaw the
244
frozen battery completely, 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 batteries generate explosive gases.
Keep sparks, flame and lighted cigarettes
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 battery. Use of
batteries of different voltage or substantial­
ly different "Ah" rating may cause an explo­
sion and personal injury .
- Never charge a frozen battery. Gas trapped in the ice may cause an explosion .
- Never charge or use a battery that has been
frozen . The battery case may have be weak­
ened .
- Use of batteries of different voltage or sub­ stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
~page 188.
CD Note
-Applying a higher voltage booster battery
will cause expensive damage to sensitive
electronic components, such as control
units, relays, radio, etc.
- There must be no electrical contact between
the vehicles as otherwise current could al­
ready start to flow as soon as the positive
(+) terminals are connected.
@ Tips
The discharged battery must be properly con-
nected to the vehicle's electrical system. .,..
