A dischar ged battery may freeze at temp era-

During starting assistance or battery charging,
battery gas can be released. #
Always allow a battery tothaw before

clus ter do not light up at low temp eratures, it is
ve ry likely that the dischar ged battery has frozen.
In this case you may neither jump-start theve hi-

The service life of a bat tery that has been thawed
may be dramatically shor tened. The starting char-

The wheels, valves or tyres could be damaged.
To o low a tyre pressure can lead tothe tyres
bursting. #
Examine the tyres forfo re ign objects. #
Check whe ther the tyre has a puncture
or theva lve has a leak. #
Ifyo u are unable torectify the damage,
contact a quali/ed specialist workshop. Information on

fo rth eve hicle's factor y-/tted tyres can be found
on the tyre pressure table on the inside of the fuel

Use a suitable pressure gauge tocheck the tyre
pressure. The outer appearance of a tyre does not
permit any reliable conclusion about the tyre pres-

Only cor rect tyre pressures when the tyres are
cold. Conditions for cold tyres:
R The vehicle has been par ked with the tyres out
of direct sunlight for at least thre e hours. R
The vehicle has tr avelled less than 1.6 km.
The vehicle's tyres heat up when driving. As the
