Replacing the battery
Note
Any deviation from the instructions
given in this paragraph may lead to
a temporary deactivation of the
stop- start system.
Only use batteries that allow the fuse
box to be mounted above the battery.
In vehicles with stop-start system,
ensure to have the AGM (Absorptive
Glass Mat) battery replaced with an
AGM battery again.
An AGM battery can be identified by
the label on the battery. We
recommend the use of an original
GM battery.
Note
Using an AGM battery different
from the original GM battery might
result in a lower performance of
the stop-start system.
We recommend that you have the
battery replaced by a repairer.
Charging the battery
Diesel fuel filter
Draining water from the fuel
filter
If water in fuel gets into the engine
and fuel system, it may cause
serious damage to the fuel system.
When the water level in fuel filter
exceeds a certain level, water in fuel
warning light q is illuminated.
Have the vehicle checked by a
repairer.
Wiper blade replacement
Properly functioning windshield
wipers are essential for clear vision
and safe driving. Regularly check the
condition of the wiper blades.
Replace hard, brittle or cracked
blades or those that smear dirt on the
windshield.
Foreign material on the windshield or
wiper blades can reduce the
effectiveness of the wipers. If the
blades are not wiping properly, clean
both the windshield and the blades
with a good cleaner or mild
detergent. Rinse them thoroughly
with water.
Repeat the process, if necessary.
There is no way to remove traces of
silicone from glass. Therefore never
apply silicone polish or wax polish to
your vehicle's windshield or you may
have streak marks, blade chatter or
blade noise that impairs the driver's
vision.
{Warning
On vehicles with stop-start system,
ensure that the charging potential
does not exceed 14.6 volts when
using a battery charger. Otherwise
the battery might be damaged.
