2009 OPEL MERIVA wheel size

46 Seats, InteriorzSit with your shoulders as far back
against the backrest as possible. Set the
backrest rake so that you can easily
reach the steering wheel with your arms
slightly bent. Mainta in contact between
your shoulders and the backrest when
turning the steering wheel. Do not angle
the backrest too far back. We
recommend a maximum rake of
approx. 25.
z Adjust the steering wheel 35.
z Set seat height 3 high enough to have a
clear field of vision on all sides and of all
display instruments. There should be at
least six inches of clearance between
your head and the headlining. Your
thighs should rest lightly on the seat
without pressing into it.
z Adjust the head restraint.
z Adjust the height of the seat belt 362.
z Adjust the lumbar support 3 so that it
supports the natural shape of the spine.

Driving and operation
Picture no: 14723s.tif
Hand brake Always apply hand brake firmly without
pressing the release button, and apply as
firmly as possible on steep slopes.
To release the hand brake pull lever up
slightly, press release button, and lower
lever all the way down.
To reduce the operating forces of the hand
brake, depress the foot brake at the same
time.
Brake assist If the brake pedal is operated quickly with
a powerful push, the vehicle is
automatically braked at full braking power
in order to achieve the shortest possible
braking distance when full-on braking
occurs (brake assist).
Maintain steady pressure on the brake
pedal for as long as full-on braking is to
continue. When the brake pedal is
released, the maximum brake force
amplification is taken away. Hill Start Assist
3 (HSA)
The system helps pull away on inclines.
After releasing the footbrake, if the hand
brake is not applied the brakes are only
released after 2 seconds. As soon as the
acceleration is sufficient to prevent rolling
back, the brake is released.
Wheels, tyresSuitable tyres and restrictions 3 228.
Tyres fitted in the factory are adapted to
the chassis and provide optimum driving
comfort and safety.
Changing tyre/wheel type
If tyres of a different size than those fitted
at the factory are used, it may be
necessary to reprogram the electronic
speedometer and make other vehicle
modifications.
After converting to a different tyre size,
have the adhesive label with tyre pressures
replaced.
9 Warning
Use of unsuitable tyres or wheels may
lead to accidents and render the vehicle
unroadworthy.

154 Driving and operationFitting new tyres
Fit tyres in pairs or in sets, which is even
better. Ensure that tyres on one axle are
zthe same size
z the same design
z the same make
z and have the same tread pattern
Fit directional tyres such that they roll in the
direction of travel. The rolling direction is
indicated by a symbol (e.g. an arrow) on
the sidewall.
Tyres fitted opposing the rolling direction
(such as when changing a tyre) should be
refitted as soon as possible. This is the only
way to benefit fully from the design
properties of the tyre.
Pay attention to legal requirements when
disposing of tyres.

Tyre pressure
Check tyre pressure, including the spare
wheel, at least every 14 days and prior to
any long journey; the tyres should be
checked when cold. Do n’t forget to check
the spare wheel 3.
Remove the valve cap key from the tank
flap and use it to unscrew the valve cap.
Tyre pressure 3228 and on the adhesive
label 3 on the inside of the tank flap.
The tyre pressure data is for cold tyres. It
applies to both summer and winter tyres. Always inflate the spare wheel
3 to the
pressure specified for full load.
Do not reduce tyre pressure when the tyres
are warm. Otherwise the pressure may
drop below the permissible minimum when
the tyres cool down.
After having checked the tyre pressure,
tighten the valve caps using the valve cap
key.
Incorrect inflation pressures will impair
safety, vehicle handling, comfort and fuel
economy and will increase tyre wear.

Vehicles with tyre repair kit 3
The jack and tyre repair kit are located in
the storage compartment below the floor
covering in the luggage compartment.

Spare wheel
3
Some vehicles are equipped with a tyre
repair kit instead of a spare wheel 3178.
Storing the spare wheel in the luggage
compartment
The spare wheel is in the luggage
compartment below the floor cover. It is
mounted via a wing nut in a well in the
vehicle floor.
To access the spare wheel, remove the
luggage compartment cover 3 3 55, lift
the floor cover using the handle and raise
toward the front. Fold the spare wheel
cover up toward the front. Placing wide wheels in the spare wheel
well
The spare wheel well is not designed for all
sizes of permitted tyres. If a wider wheel is
stowed in the spare wheel well after
changing wheels, the floor cover can rest
on the protruding wheel.
This must be taken into account when
loading the luggage compartment.

228 Technical DataTyres Restrictions
Not all tyres available on the market
currently meet the structural requirements.
We recommend that you consult an Opel
Partner concerning suitable tyre makes.
These tyres have undergone special tests
to establish their reliability, safety and
specific suitability for Opel vehicles.
Despite continuous market monitoring, we
are unable to assess these attributes for
other tyres, even if they have been granted
approval by the relevant authorities or in
some other form.
Further information 3153. Winter tyres
3
Tyres of size 205/50 R 16 are not suitable
for use as winter tyres except on vehicles
with the Z 16 LET engine.
Tyres of size 205/45 R 17 are not suitable
for use as winter tyres. If winter tyres are in use, the spare wheel
may still be fitted with a summer tyre. Use
of the spare wheel may alter vehicle
handling. Obtain a replacement for the
faulty tyre as soon as possible, and have
the wheel balanced and fitted to the
vehicle.
Further information 3
157.
Tyre chains
3
Tyre chains may be used on the front
wheels only.
We recommend the use of tyre chains with
a fine mesh that add no more than 10 mm
to the running surface and the insides of
the tyres (including chain lock).
Tyre chains are not permitted on tyre
sizes 205/50 R 16 and 205/45 R 17.
Further information 3157. Wheels Wheel bolt tightening torque: 110 Nm.
Spare wheel
3
Depending on model, the spare wheel is
designed as a temporary spare wheel 3.
When using the spare wheel, the driving
behaviour may be modified. Replace the
faulty tyre as soon as possible, balance the
wheel and refit to vehicle. Follow the notes
on this page and 3157, 3173.
On vehicles with alloy wheels 3 the spare
wheel may have a steel rim.
The spare wheel can be fitted with a
smaller tyre
1)and a smaller rim than the
wheels fitted on the vehicle.
Tyre pressure (overpressure) The specified tyre pressures are valid for
cold tyres. The increased tyre pressure
resulting from extensive driving must not
be reduced. The tyre pressures specified on
the following pages apply to both summer
and winter tyres.
The spare wheel must always be inflated to
the tyre pressure for a full load – see table
on following pages.
Further information 3153 to 3157. 1)Country-specific version: The spare wheel is
only to be used as a temporary spare wheel.
