Vehicle care1619Warning
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 released 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.
Washer fluid
Fill with clean water mixed with a
suitable quantity of approved
windscreen washer fluid which
contains antifreeze.
Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
Washer fluid 3 203.
Brakes
In the event of minimum thickness of
the 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.

162Vehicle care
The brake fluid level must be betweenthe MIN and MAX marks.
If fluid level is below the MIN mark,
seek the assistance of a workshop.
Brake and clutch fluid 3 203.
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 vehicle 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 3 108.
Disconnecting 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 section may lead to
temporary deactivation or
disturbance of the stop-start system.
When the vehicle battery is being
replaced, please 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.
Ensure that the battery is always
replaced by the same type of 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.

182Vehicle careThe use of commercially-availableliquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
Operating electronic devices or being close to facilities using similar wave
frequencies could disrupt the tyre
pressure monitoring system.
Each time the tyres are replaced, tyre
pressure monitoring system sensors
must be dismounted and serviced. For the screwed sensor; replace
valve core and sealing ring. For the
clipped sensor; replace complete
valve stem.
Vehicle loading status
Adjust tyre pressure to load condition according to the tyre information labelor tyre pressure chart 3 214, and
select the appropriate setting in the menu Tyre Load in the Driver
Information Centre, Vehicle
Information Menu 3 83 . This setting is
the reference for the tyre pressure
warnings.
The menu Tyre Load only appears
when the vehicle is at a standstill and
the parking brake is applied.On vehicles with automatic
transmission, the selector lever must
be in P.
Midlevel display:
Select ● LO for comfort pressure up to
three people.
● ECO for Eco pressure up to three
people.
● Hi for full loading.
Uplevel display:
Select ● Light for comfort pressure up to
three people.
● Eco for Eco pressure up to three
people.
● Max for full loading.
Tyre pressure sensor matching
process
Each pressure sensor has a unique identification code. The identification
code must be matched to a new
wheel position after rotating the
wheels or exchanging the complete
wheel set and if one or more tyre
pressure sensors were replaced. The
Page 185 of 231

Vehicle care183tyre pressure sensor matching
process should also be performed
after replacing a spare wheel with a
road wheel containing a tyre pressure
sensor.
The malfunction light w and the
warning message or code should
extinguish at the next ignition cycle. The sensors are matched to the
wheel positions, using a relearn tool,
in the following order: left side front
wheel, right side front wheel, right
side rear wheel and left side rear
wheel. The turn light at the current
active position is illuminated until
sensor is matched.
Consult a workshop for service. There
are 2 minutes to match the first wheel position, and 5 minutes overall to
match all four wheel positions. If it
takes longer, the matching process
stops and must be restarted.
The tyre pressure sensor matching
process is:
1. Apply the parking brake.
2. Turn the ignition on.3. On vehicles with automatic transmission: set the selector
lever to P.
On vehicles with manual
transmission: select neutral.
4. Use MENU on the stalk to select
the Vehicle Information
Menu ? in the Driver
Information Centre.
5. Turn the adjuster wheel to scroll to
the tyre pressure menu.
Midlevel display:
Uplevel display:
6. Press SET/CLR to begin the
sensor matching process. A
message requesting acceptance
of the process should be
displayed.
7. Press SET/CLR again to confirm
the selection. The horn sounds
twice to indicate that the receiver
is in relearn mode.
8. Start with the left side front wheel.
9. Place the relearn tool against the tyre sidewall, near the valve stem.Then press the button to activate
the tyre pressure sensor. A horn
chirp confirms that the sensor
identification code has been
matched to this wheel position.
