The battery is located in the engine compart­
ment. Before you check anything in the engine
compartment,
read and heed all WARNINGS
c::>& .
Always heed the safety warnings, when wo rking
on the vehicle battery or the vehicle electrical
system to prevent injury.
The following WARNINGS are very important
when working on the battery:

BOLS and safety precautions when working on
the battery.
®
Always wear eye protection.
&
Battery acid contains sulfuric acid. Al-
ways wear glov es and eye protection .
@
No

- flames
- smoking.
~
When a battery i s 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,
accident and even fire . Read and heed the fol­
lowing WARNINGS:
-Always wear eye protection. Do not let bat­
tery acid or any lead particles get on your
skin or clothing. Shield your eyes. Exp losive
gases can cause blindness or other injury .
- Battery acid contains su lfuric acid. Sulfuric
acid can cause blindness and severe burns.
-
Checking and Filling
-Always wear gloves and eye protection. Do
not tilt the battery because acid could leak
out of the ventilation openings.
- If you get battery acid in your eyes or on
your skin, immed iate ly r inse with cold wa­
ter for several minutes and get med ical at­
tent ion.
- If you shou ld ingest any battery acid, seek
med ica l attent ion immed iate 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 cou ld
lead to damage or explosion and personal
injury .
- When a battery is charged, it produces hy­
drogen gas which is explosive and could
cause personal injury.
- Always keep the battery well out of the
reach of children .
- Before work is done on the e lectrical sys­
tem, disconnect the negat ive ground cable.
- Before performing any work on the electri­
cal system, sw itch off the engine and ign i­
tion as well as any electrical equipment. The
negat ive cable on the battery must be dis­
connected. If you are just going to replace a light bulb, then it is enough to swi tch off
the lights.
- Before disconnecting the battery, switch off
the anti-theft alarm system! Otherwise you
will set off the alarm.
- When disconnecting the battery, first dis­
connect the negative cable and then the
positive cable.
- Before reconnecting the battery, make sure
all electrical consumers are switched off.
Reconnect the positive cable first and then
the negative cable. Never interchange the
cables -this could start a fire!

To reduce the risk of lime sca le deposits on the
spray nozzles, use clean water with low amounts
of calci um. Always add window cleaner to the wa­
t er. When the outside temper atures are co ld, an
anti-free zing agent should be added to the water
so that it does not freeze .
Cl) Note
-The concentration of anti-free zing agent
must be adjusted to the vehicle operating
conditions in the respective climate. A con ­
centration that is too high can lead to veh i­
cle damage .
- Never add rad iator anti -freeze or other addi ­
tives to the washer fluid .
- Do not use a glass cleaner that contains
paint solvents, beca use this could damage
the pa int.
Service interval display
The service interval display detects when your ve­
hicle is due for service.

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
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary, the engin e 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
handling 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
356
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 304.
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. .,..
