Replacing the battery
Your veh icle is equipped with an inte llige nt ene r­
gy management system for d istr ibut ing elect rici ­
ty ¢
page 138. The battery cha rges better in
vehicles with the en ergy management system
than in vehicles without the system. To ensure
that th e additional pow er is availabl e after re ­
p lac ing the battery, rep lacing w ith the same type
of b attery from the s ame manufac turer ( like the
battery that was delivered with the veh icle) is
recommended . Yo ur authorized deale r must code
the battery in the energy management system to
Ch eck ing and Filling
enable you to use the energy management func­
tions corr ectly aft er replacing the batt ery .
If it is no t possib le to use a battery of this type,
the new battery mus t have the same capacity,
vo ltage ( 12-volts), amperage, construction and
plug sealing.
When install ing the battery, make sure the ig ni­
t ion and all electr ica l cons umers are tu rned off.
Q) Note

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. .,..

When jump starting or charging the battery,
never connect the negative ground cable to
the battery negative post because the battery
manager system must be able to detect the
battery's state of charge . Always connect the
negative ground cable to the negat ive ground
post of the battery manager control unit .
Using the jump start
cable
Both jump start cables must be connected in the
correct order!

the negative terminal @on the battery that
i s p roviding the current@.
4. Secure the other end of the negative cable
(black) to the jump start pin@ (hex head pin
= "negative") on the vehicle that needs to be
started @.
Starting the engine
.. Start the engine on the vehicle providing the
jump start @and let it run at idle .
.. Now start the engine on the vehicle with the
drained battery @ .
.. If the engine does not start, stop the starting
procedure after 10 seconds and then repeat it
after approx imately 30 seconds .
.. Remove the cables when the engines are run­
ning. Remove them in reverse order from the
way they were installed.
.. Close the red cover on the positive terminal.
T he battery is vented to the outside to prevent
gases from enter ing the vehicle interior . Make
s ur e that the jumper clamps are well connected
with their
metal ports in full contact with the
battery terminals.
_& WARNING
-To avoid serious personal injury and damage to the vehicle, heed all warnings and instruc ­
tions of the jumper cable manufacturer. If in
doubt, call for road service.
- Jumper cables must be long enough so that
the vehicles do not touch . ..,_
357

Emergency situations
-When connecting jumper cables, make sure
that they cannot get caught in any moving
parts in the engine compartment.
- Do not bend over the batteries -danger of
chemical burns!
- The battery cell locking screws must be
tightened securely.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS

(D Note
Improper hook-up of jumper cables can ruin
the generator.
- Always connect POSITIVE(+) to POSITIVE
(+), and NEGATIVE(-) to NEGATIVE(-)
ground post of the battery manager control
unit.
- Check that all screw p lugs on the battery
cells are screwed in firmly. If not, tighten
plugs prior to connect ing clamp on negative
battery terminal.
- Please note that the procedure for connect ­
i ng a jumper cable as described above ap­
plies specifically to the case of your vehicle
being jump started . When you are giving a
ju mp start to another vehicle, do
not con­
nect the negative (-) cable to the negative
(-) terminal on the discharged batte ry @
