warning VAUXHALL MERIVA 2014.5 Repair Manual

154Driving and operating
Pressing the LPG button switches
between petrol and liquid gas
operation as soon as the required
parameters (coolant temperature,
gas temperature and minimum
engine speed) have been reached.
The requirements are usually fulfilled
after around 60 seconds (depending
on exterior temperature) and the first
firm press on the accelerator. The
LED status shows the current
operating mode.1 off=petrol operation1 illumi‐
nates=liquid gas operation1 flashes=no switching is
possible, one type
of fuel is empty
As soon as the liquid gas tanks are
empty, petrol operation is
automatically engaged until the
ignition is switched off.
Every six months, run the petrol tank
down until control indicator i
illuminates, then refuel. This helps
maintain fuel quality and system
function for petrol operation.
Fill the tank completely at regular
intervals to prevent corrosion in the
tank.
Faults and remedies
If gas mode is not possible, check the following:
■ Is there enough liquid gas present?
■ Is there enough petrol present for starting?
Due to extreme temperatures in
combination with the gas
composition, it may take slightly
longer before the system switches
from petrol to liquid gas mode.
In extreme situations, the system may
also switch back to petrol mode if the
minimum requirements are not
fulfilled.
Seek the assistance of a workshop in the event of all other faults.Caution
Repairs and adjustments may onlybe made by trained specialists in
order to maintain the safety and
warranty on the LPG system.
Liquid gas is given a particular odour
(odorised) so that any leaks can be
detected easily.
9 Warning
If you smell gas in the vehicle or in
the immediate vicinity, switch to petrol mode immediately. No
smoking. No naked flames or
ignition sources.
If possible, close the manual shut-off
valve on the multivalve. The
multivalve is located on the liquid gas
tank in the load compartment,
underneath the rear floor cover.

Driving and operating157
Screw the required adapter hand-
tight onto the filler neck.
ACME Adapter: Screw the nut of the
filling nozzle onto the adapter. Press
locking lever on filler nozzle down.
DISH (Italy) filler neck: Place the filler
nozzle into the adapter. Press locking lever on filler nozzle down.
Bayonet filler neck: Place filler nozzle
on the adapter and turn to the left or
right through one quarter turn. Pull
locking lever of filler nozzle fully.
EURO filler neck: Press the filler
nozzle onto the adapter until it
engages.
Press the button of the liquid gas supply point. The filling system stops
or begins to run slowly when 80% of
the tank volume is reached
(maximum fill level).
Release button on filling system and
the filling process stops. Release the
locking lever and remove the filler
nozzle. A small quantity of liquid gas
can escape.
Remove adapter and stow in vehicle.
Fit protective cap to prevent the
penetration of foreign bodies into the
filler opening and the system.9 Warning
Due to the system design, an
escape of liquid gas after
releasing the locking lever is
unavoidable. Avoid inhaling.
9 Warning
The liquid gas tank may only be
filled to 80% for safety reasons.
The multivalve on the liquid gas tank
automatically limits the fill quantity. If
a larger quantity is added, we
recommend not exposing the vehicle
to the sun until the excess amount
has been used up.
Filling adapter
As filling systems are not
standardised, different adapters are
required which are available from
Vauxhall Distributors and from
Vauxhall Authorised Repairers.

Driving and operating159

General information
Only use towing equipment that has
been approved for your vehicle.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case use the coupling ball
bar for towing. Always keep the
coupling ball bar in the vehicle.
Driving characteristics and
towing tips Before attaching a trailer, lubricate
the coupling ball. However, do not do so if a stabiliser, which acts on the
coupling ball, is being used to reduce
snaking movements.
For trailers with low driving stability
and caravan trailers with a permitted
gross vehicle weight of more than1100 kg the use of a stabiliser is
strongly recommended when driving
above 50 mph.
If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 224.

Performing work9 Warning
Only perform engine compartment
checks when the ignition is off.
The cooling fan may start
operating even if the ignition is off.

168Vehicle care
If the cooling system is cold, the
coolant level should be above the
filling line mark. Top up if the level is
low.
9 Warning
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.
Washer fluid
Fill with clean water mixed with a
suitable quantity of 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.
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.

170Vehicle care
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 vehicle 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
Vauxhall vehicle battery.
Notice
Using an AGM vehicle battery
different from the original Vauxhall
vehicle battery may result in a lower performance of the stop-start
system.9 Warning
When fitting a battery with a length
deviating from the original one, itis essential to ensure a proper
fitting of the buffer element.
We recommend that you have the
vehicle battery replaced by a
workshop.

Tyre pressures differ depending onvarious options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 215.
2. Identify the respective tyre.
The tyre pressure tables show all possible tyre combinations 3 224.
For the tyres approved for your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
If the tyre pressure must be reduced
or increased on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Tyre deflation detection system The tyre deflation detection system
continually checks the rotation speed
of all four tyres.
If a tyre loses pressure the control
indicator w illuminates yellow and a
warning message is displayed in the
Driver Information Centre with
Uplevel-Display. Stop immediately
and check tyre pressure.

System initialisation After tyre pressure correction or
wheel change, the system must be
initiated:
1. Apply electrical parking brake.
2. Press the MENU button to select
the Vehicle Information Menu .3. Turn the adjuster wheel to select
Tire Pressure System .
4. Press the SET/CLR button to
select the reset of the system.
On vehicles with Midlevel- Display, make a longer press on
the SET/CLR button to start the
initialisation of the system.
5. On vehicles with Uplevel-Display, the selection is confirmed by a
pop-up indication. Confirm to start
the initialisation of the system.
Selection and indication can be
different between Midlevel-Display
and Uplevel-Display.

Vehicle care191
If the system is ready again, a
message is displayed in the Driver
Information Centre with
Uplevel-Display.
Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than 2 mm.The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels periodically. Ensure that
the direction of rotation of the wheels
remains the same.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel
size If tyres of a different size than those
fitted at the factory are used, it may be necessary to reprogramme the
speedometer as well as the nominal
tyre pressure and make other vehicle
modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
Wheel covers
Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.
9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
