tire sealant.Observe the maximum permissible speed of
50 mph (80 km/h) for a tire sealed with tire
sealant.*NOTE Staining caused by leaking tire seal-
ant
Aser use, excess tire sealant may leak out
from the Nlling hose.
Therefore, place the Nlling hose in the
plastic bag that contained the TIREFIT
kit.+ENVIRONMENTAL NOTE Environmental
pollution caused by environmentally irre-
sponsible disposal

Notes on starting assistance and charging the 12
V battery
All vehicles
When charging the battery and during starting
assistance, always use the jump-start connection
point in the engine compartment.
*NOTE Damage to the battery due to over-
voltage
When charging using a battery charger without
a maximum charging voltage, the battery or the on-board electronics may be damaged.
Only use battery chargers with a maxi-
mum charging voltage of 14.8 V.&WARNING Risk of explosion due to the
ignition of hydrogen gas
If there is a short circuit or sparks are created,
there is a danger of hydrogen gas igniting
when you charge the battery.
Make sure that the POSITIVE terminal of
a connected battery does not come into
contact with vehicle parts.Never place metal objects or tools on a
battery.When connecting and disconnecting the battery, always observe the sequence of
battery terminals described.During starting assistance, always take
care to connect only battery terminals of
identical polarity.During starting assistance, observe the sequence described for connecting and
disconnecting the jumper cables.Do not connect or disconnect the bat-
tery terminals with the engine running.&WARNING Risk of explosion due to a mix-
ture of explosive gases
A mixture of explosive gases can escape from

Fire, open Oames, smoking and creating
sparks must be avoided.Make sure that there is suPcient ventila-
tion.Do not stand over the battery.&WARNING Risk of explosion from a frozen
battery
A discharged battery may freeze at tempera-
tures slightly above or below freezing point.
During starting assistance or battery charging,
battery gas can be released.
Always allow a battery to thaw before
charging it or performing starting assis-
tance.
If the indicator/warning lamps on the instrument cluster do not light up at low temperatures, it is
very likely that the discharged battery has frozen.
In this case, you may neither jump-start the vehi-
cle nor charge the battery.
The service life of a battery that has been thawedmay be dramatically shortened. The starting char-
acteristics may be impaired, especially at low
temperatures.
It is recommended that you have a thawed battery checked at a qualiNed specialist workshop.

tance and when charging the battery:
= Use only undamaged jumper cables/charging
cables with a suPcient cross-section and
insulated terminal clamps.
= Non-insulated parts of the terminal clamps
must not come into contact with other metal
parts while the jumper cable/charging cable
is connected to the battery/jump-start con-
nection point.
= The jumper cable/charging cable must not
come into contact with any parts that may move when the engine is running.
= Always make sure that neither you nor the bat-
tery is electrostatically charged.
