Tyre condition, wheel condition
Drive over edges slowly and at right angles
if possible. Driving over sharp edges can
cause tyre and wheel damage. Do not trap
tyres on the kerb when parking.
Regularly check wheels for damage. Seek
the assistance of a workshop if there is any
damage or unusual wear.
Picture no: 6457u.tif
Tread depth
Check tread depth regularly.
For reasons of safety, tyres should be
replaced when their tread depth has worn
down to 2 to 3 mm (winter tyres: 4 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 wear indicators (TWI
1)). A number of
wear indicators are spaced at equal
intervals around the tyre within the tread.
Their position is indicated by markings on
the tyre sidewall.
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 wear in the front is greater than that in
the rear, move the rear wheels to the front
axle and vice versa.
Correct tyre pressure. General information
z
The risk of aquaplaning is greater if the
tyres are worn.
z Tyres age, even if they are not used or
used infrequently. We recommend tyre
replacement every six years at the latest.
z Never fit used tyres the previous history
and use of which you do not know. Tyre designations
Meanings:
e.g.
175/70 R 14 88 T
Speed code letters:
175 = Tyre width in mm
70 = Cross-section ratio (tyre height to
tyre width in %)
R = Belt type Radial
14 = Rim diameter in inches
88 = Load index e.g. 88 corresponds
to 567 kg
T = Speed code letter:
Q = Up to 160 km/h
S = Up to 180 km/h
T = Up to 190 km/h
H = Up to 210 km/h
V = Up to 240 km/h
W = Up to 270 km/h

Driving and operation
Winter tyres 3
Notes on fitting new tyres 3 154.
Restrictions 3228.
Winter tyres improve driving safety at
temperatures below 7 C.
The design of summer tyres means they
have limited qualities for winter driving.
In accordance with country-specific
regulations, affix the speed sticker 3 in the
driver’s field of view.
If you use the spare wheel when it is fitted
with a summer tyre, the vehicle’s
driveability may be affected, especially on
slippery road surfaces. Obtain a
replacement for the faulty tyre as soon as
possible, and have the wheel balanced
and fitted to the vehicle.
Wheel covers 3
Use of wheel trims and tyres that approved
by Opel for the vehicle in question and
thereby fulfil all requirements for the wheel
and tyre combination.
If the wheel trims and tyres used are not
Opel-approved, the ty res must not have a
beaded edge. Wheel trims must not impair brake cooling.
Remove the wheel trims if fitting tyre
chains
3.
Picture no: 6459u.tif
Tyre chains 3
Restrictions and further information 3 228.
Tyre chains are only permitted on the
driven wheels (front axle). They must be
fitted to the tyres symmetrically in order to
achieve a concentric fit.
Always use fine mesh chains that add no
more than 10 mm to the tyre tread and the
inboard sides (including chain lock).
9 Warning
Use of unsuitable tyres or wheel trims
could lead to sudden loss of air and
thereby accidents.

158 Driving and operationRemove the wheel trims if using tyre chains
3174.
Tyre chains may only be used at speeds up
to 50 km/h. When travelling on roads that
are free of snow, they may only be used for
brief periods.
Tyre chains must not be used on the
temporary spare wheel. If you need to use
tyre chains after suffering a flat front tyre,
fit the temporary spare on the rear axle
and transfer one of the rear wheels to the
front axle.
Roof rack
3
For safety reasons and to avoid roof
damage we recommend using the Opel
roof rack system that is approved for your
vehicle.
Follow the usage instructions for the roof
rack.
Remove the roof rack when not in use.
Disengage covers concealing roof rack
mounts by pushing sliders in direction of
arrow (e.g. with coin) and remove. To close
roof rack mounts, insert covers at front and
engage sliders at rear.
Driving hints 3 135
Towing equipment
3
Only use towing equipment that has been
approved for your vehicle. Ask a workshop
to retrofit towing equipment. It may be
necessary to make changes that affect the
cooling system, heat shields or other
equipment.
Mounting dimensions of towing equipment
3232.
9 Warning
Damage may lead to tyre blowout.

Towing equipment with
removable coupling ball bar

Stowage of coupling ball bar
The coupling ball bar is located in a bag
with the vehicle tools housed under the
spare wheel - see Fig. above.
Spare wheel 3 3172.
On vehicles with tyre repair kit 3, the
coupling ball bar is located in the left
stowage compartment beneath the floor
cover in the luggage compartment 3162,
Fig. 17923 S.
Picture no: 15271s.tif
Fitting the coupling ball bar
Fold down the socket. Remove the sealing
plug from the hole for the coupling ball bar
and stow it in the luggage compartment.
Picture no: 12416t.tif
Checking the tensioning of the coupling ball bar

z Red marking on rotary knob must point
towards white marking on coupling ball
bar.
z The gap between the rotary knob
and the coupling ball bar must be
approx. 4 mm.
z Key in the lock must be at position 1.
Caution
The coupling ball bar is to be removed
when not towing.

downwards.
Insert the sealing plug in the opening for
the coupling ball bar. Close the socket
3 159, Fig. 15271 S.
9 Warning
Towing a caravan/trailer is only
permitted with a properly fitted coupling
ball bar. If the coupling ball bar cannot
be correctly fitted, please contact a
workshop for assistance.

Stowage of coupling ball bar
Place coupling ball bar in bag and clip onto
the tool kit below the spare wheel 3159,
Fig. 14195 S.
On vehicles with tyre repair kit 3, the
coupling ball bar is stored in the left
stowage compartment beneath the floor
cover in the luggage compartment - see
Fig. above.
Caravan/trailer towingCaravan and trailer loads
1)
The permissible caravan/trailer loads are
vehicle and engine-dependent maximum
values which must not be exceeded. The
actual caravan/trailer load is the difference
between the actual gross weight of the
caravan/trailer and the actual coupling
socket load with the caravan/trailer
coupled.
The permissible caravan/trailer loads are
specified in the vehi cle documents. In
general, they are valid for gradients up to
maximum 12% The permitted caravan/trailer load applies
up to the specified incline and up to an
altitude of 1000 metres above sea level.
Since engine power decreases as altitude
increases because of the air becoming
thinner, therefore reducing climbing ability,
the permitted towing weight also
decreases by 10 % for
every 1000 metres of
additional altitude. The towing weight
does not have to be reduced when driving
on roads with slight inclines (less than 8 %,
e.g. motorways).
The permissible gross train weight must not
be exceeded. This weig ht is specified on
the identification plate 3218. 1)Observe national regulations.
