Volvo S60 2018 Owner's Manual page 441

WARNING
The battery can generate oxyhydrogen
•
gas, which is highly explosive. A spark can
be formed if a jump lead is connected
incorrectly, and this can be enough for
the battery to explode.
Do not connect the jump leads to any
•
fuel system component or any moving
part. Be careful of hot engine parts.
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 imme-
diately.
Never smoke near the battery.

NOTE
If the starter battery has been discharged so
much that the car has no normal electrical
functions and the engine is then jump-started
with an external battery or a battery charger,
the Start/stop function may continue to be
activated. If the Start/stop function then auto-
stops the engine shortly afterwards, there is a
great risk that engine auto-start will fail due
to insufficient battery capacity, because the
battery has not had the time to recharge.
If the car has been jump-started, or if there is
insufficient time to charge the battery with a
battery charger, the Start/stop function is
temporarily deactivated until the battery has
been recharged by the car. In an outside tem-
perature of approx. +15 °C (approx. 60 °F),
the battery needs to be charged for at least
1 hour by the car. In a lower outside tempera-
ture, the charging time may increase to
3–4 hours. The recommendation is to charge
the battery using an external battery charger.

STARTING AND DRIVING
Towbar*
The car can be equipped with a towbar that
makes it possible to tow e.g. a trailer behind the
car.
There may be different towbar variants available
for the car. Contact a Volvo dealer for more infor-
mation.
IMPORTANT
When the engine is switched off, the constant
battery voltage to the trailer connector can be
switched off automatically so as not to drain
the starter battery.
IMPORTANT
The towball needs regular cleaning and lubri-
cation with grease in order to prevent wear.
NOTE
When a hitch with a vibration damper is used,
the towball must not be lubricated.
This also applies when fitting a bicycle rack
that is clamped in around the towball.
NOTE
If the car is equipped with a towbar, there is
no rear mounting for a towing eye.
