Vehicle care231Engine coolant
The coolant provides freeze
protection down to approx. -28 °C. In
cold regions with very low
temperatures, the factory filled
coolant provides frost protection
down to approx. -37 °C.Caution
Only use approved antifreeze.
Coolant and antifreeze 3 276.
Coolant level
Caution
Too low a coolant level can cause engine damage.
If the cooling system is cold, the
coolant level should be above the
filling line mark. Top up if the level is
low.
Depending on version, the filling line
mark is inside the filler opening. To check, open the cap.
Additional cooling circuit for Turbo
engine
Coolant container is fixed to the air
cleaner housing.
If the cooling system is cold, the
coolant level should be above the
filling line mark. Top up if the level is
low.
Page 234 of 327
232Vehicle careGeneral9Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up, use a 1:1 mixture of
approved coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Power steering fluid
Caution
Extremely small amounts of
contamination can cause steering
system damage and cause it to not
work properly. Do not allow
contaminates to contact the fluid
side of the reservoir cap/dipstick or
from entering the reservoir.
Power steering fluid level normally
does not have to be checked. If an
unusual noise sounds during steering or the power steering reacts
conspicuous seek the assistance of a
workshop.
Washer fluid
Fill with clean water mixed with a
suitable quantity of approved
windscreen washer fluid which
contains antifreeze.
Page 235 of 327

Vehicle care233Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
after a sudden drop in
temperature.
Use of washer fluid containing
isopropanol can damage exterior
lamps.
Washer fluid 3 276.
Brakes In the event of minimum thickness ofthe brake lining, a squealing noise
sounds during braking.
Continued driving is possible but
have the brake lining replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake fluid9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes, skin, fabrics and painted surfaces.
The brake fluid level must be betweenthe MIN and the MAX marks.
If fluid level is below MIN seek the
assistance of a workshop.
Brake and clutch fluid 3 276.
Vehicle battery
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
four weeks can lead to vehicle battery discharge. Disconnect the clamp from
the negative terminal of the vehicle
battery.
Ensure the ignition is switched off
before connecting or disconnecting
the vehicle battery.
Battery discharge protection 3 140.

234Vehicle careDisconnecting the battery
If the vehicle's battery is to be
disconnected (e.g. for maintenance
work), the alarm siren must be
deactivated as follows: Switch the
ignition on then off, then disconnect
the vehicle's battery within
15 seconds.
Replacing the vehicle battery Note
Any deviation from the instructions
given in this paragraph may lead to
a temporary deactivation of the stop-
start system.The vehicle battery is covered.
Remove the cover to replace the battery. Lift up the cover at the rear
and unlatch it at the front.
When the battery is being replaced, ensure that there are no open
ventilation holes in the vicinity of the
positive terminal. If a ventilation hole
is open in this area, it must be closed
off with a dummy cap, and the
ventilation in the vicinity of the
negative terminal must be opened.
Only use vehicle batteries that allow
the fuse box to be mounted above the
battery.
In vehicles with an AGM (Absorptive
Glass Mat) battery, make sure to
have the battery replaced with
another AGM battery.
An AGM battery can be identified by
the label on the battery. We
recommend the use of an original
Opel battery.
Note
Using an AGM vehicle battery
different from the original Opel
vehicle battery may result in a lower performance.
We recommend that you have the
vehicle battery replaced by a
workshop.

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.
