Tyre designations
Meanings:
e.g. 235/60 R 17 102 H
Speed code letters: Winter tyres
3
See page 223 for restrictions.
Winter tyres improve safety at extremely
low outside temperatures and should
therefore be fitted on all wheels.
The design of summer tyres means they
have limited qualities for winter driving.
If the maximum permissible speed for the
winter tyres is less than that of the vehicle,
a notice indicating the maximum
permissible speed for the tyres must be
affixed within the driver's field of vision 3
1).
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.
Ensure that winter tyres are inflated to the
correct pressure specified by the tyre
manufacturer.
If winter tyres are installed that have not
been approved for your vehicle, ESC
performance may be affected. Consult a
workshop regarding availability of
approved winter tyres.
Wheel trims 3
If the wheel trims and tyres used are not
Opel-approved, make sure the tyres do not
have a beaded edge - see page 149. Tyre chains
3
See page 223 for restrictions.
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 wheel on the rear
axle and transfer one of the rear wheels to
the front axle.

zNever expose the battery to naked
flames or sparks.
z A discharged battery can freeze at
temperatures of 0
°C. Defrost the battery
in a warm room before connecting the
jump leads.
z Do not allow battery fluid to contact
eyes, skin, fabrics or painted surfaces.
The fluid contains sulphuric acid which
can cause injuries and damage in the
event of direct contact.
z Wear eye protection and protective
clothing when handling a battery. z
Use auxiliary battery with same voltage
(12 volts). Its capacity (Ah) must not be
considerably less than that of the
discharged battery. Voltage and
capacity information can be found on
the batteries.
z Use jump leads with insulated terminals
and a width of at least 16 mm
2 (25 mm2
for diesel engines).
z Do not disconnect the discharged
battery from the vehicle.
z Switch off all unnecessary electrical
consumers. Infotainment system may be
damaged if switched on while jump
starting.
z Do not lean over the battery during jump
starting procedure.
z Do not allow the terminals of one lead to
touch those of the other lead.
z The vehicles should not touch while jump
starting.
z Apply hand brake.
z Manual transmissi on in neutral,
automatic transmission 3 in P. Connect the leads in th
e order shown in the
illustration:
1. Connect one end of the first jump lead to the positive terminal 1 of the battery
providing the jump start (identified by
“+” sign on battery case or terminal).
2. Connect the other end of the first jump lead to the positive terminal 2 of the
discharged battery (“+” sign).
3. Connect one end of the second jump lead to the negative terminal 3 of the
battery providing the jump start
(identified by "-" sign on battery case or
terminal).
4. Connect the other end of the second jump lead 4 to ground on the vehicle with
the discharged battery, e.g. on the
engine block.
