Jump starting
If the battery is flat then the car can be started
with current from another battery.
When jump starting the car, the following steps
are recommended to avoid short circuits or
other damage:
1. Insert the remote control key in key posi-
tion 0, see page 80.
2. Check that the donor battery has a voltage
of 12 V.
3. If the donor battery is installed in another
car - switch off the donor car's engine and
make sure that the two cars do not touch
each other.4. Connect one of the red jump lead's clamps
to the donor battery's positive terminal (1).
IMPORTANT
Connect the start cable carefully to avoid
short circuits with other components in the
engine compartment.
5. Open the clips on the front cover of the
battery in your car and remove the cover,
see page 328.
6. Connect the red jump lead's other clamp
onto the car's positive terminal (2).
7. Connect one of the black jump lead's
clamps to the donor battery's negative ter-
minal (3).
8. Connect the other clamp to a grounding
point, e.g. right-hand engine mounting at
the top, the outer screw head (4).
9. Check that the jump lead clamps are
affixed securely so that there are no sparks
during the starting procedure.
10. Start the engine of the "donor car" and
allow it to run a few minutes at a speed
slightly higher than idle approx. 1500 rpm.
11. Start the engine in the car with the dis-
charged battery.
IMPORTANT
Do not touch the crocodile clips during the
start procedure. There is a risk of sparks
forming.
12. Remove the jump leads in reverse order -
first the black and then the red.
> Make sure that none of the black jump
lead's clamps comes into contact with
the battery's positive terminal or the
clamp connected to the red jump lead!
WARNING
•The battery can generate oxyhydrogen
gas, which is highly explosive. A spark
can be formed if a jump lead is con-
nected incorrectly, and this can be
enough for the battery to explode.
•The battery contains sulphuric acid,
which can cause serious burns.
•If sulphuric acid comes into contact
with eyes, skin or clothing, flush with
large quantities of water. If acid
splashes into the eyes - seek medical
attention immediately.

327 Operation
The service life and function of the battery is
influenced by factors such as the number of
starts, discharging, driving style, driving con-
ditions, climatic conditions etc.
•Never disconnect the battery when the
engine is running.
•Check that the cables to the battery are
correctly connected and properly tight-
ened.

gas, which is highly explosive. A spark
can be formed if a jump lead is con-
nected incorrectly, and this can be

attention immediately.
NOTE
The life of the battery is shortened if it
becomes discharged repeatedly.
The life of the battery is affected by several
factors, including driving conditions and cli-
mate. Battery starting capacity decreases
gradually with time and therefore needs to
be recharged if the car is not used for a
longer time or when it is only driven short
distances. Extreme cold further limits star-
ting capacity.
To maintain the battery in good condition, at
least 15 minutes of driving/week is recom-
mended or that the battery is connected to
a battery charger with automatic trickle
charging.
A battery that is kept fully charged has a
maximum service life.
IMPORTANT
Never use a quick charger to charge the
battery.
IMPORTANT
If the following instruction is not observed
then the energy saving function for infotain-
ment may be temporarily disengaged, and/
or the message in the information display
about the main battery's state of charge
may be temporarily inapplicable, following
the connection of an external battery or bat-
tery charger:
•The negative battery terminal on the
car's main battery must never be used
for connecting an external battery or
battery charger - only the car chassis
may be used as the grounding point.
See the section "Start assistance" - for a
description of how the cable clamps must
be attached.
