Four-wheel drive

GENERAL INFORMATION

Vectra 4x4

The "Constant Drive of All Wheels" system, at the working engine is in constant readiness. The driving effort by means of not wearing out liquid coupling (Visko-mufta) automatically is distributed between forward and back wheels according to an instant ratio of forces of interaction of tires with a roadbed.

At the amplifying slipping on a forward axis (entrance on the slippery road) the most part of driving effort is redistributed on a back axis.

For ensuring normal braking at a speed over 25 km/h the drive of back wheels is switched-off, and after a brake otpuskaniye instantly turns on again.

For the physical reasons efficiency of braking of the vseprivodny car cannot be higher, than at the two-wheeled drive.

Therefore it is impossible to pass to risky style of driving.

Distribution of driving effort between four wheels gives the chance, especially in winter conditions, to overcome rises which cannot be overcome at the two-wheeled drive. On descents, however, the four-wheel drive does not give advantages in braking in comparison with two-wheeled. Overcome such sites of a way carefully.

Control lamp of the drive of all wheels

Lights up at ignition. Dies away after start of the engine.

Fire when driving, only the forward drive. If the lamp continues to burn also after new start, for elimination of malfunction to address in the workshop Opel.

Blinking, long turning on of the drive of all wheels. Immediately address in the authorized workshop Opel, at the same time conduct the car carefully as stability of braking in critical situations is limited.

The four-wheel drive increases traction effort. Gives advantages at start-off and slow driving, and also on slippery roads and difficult sites.

Distribution of driving effort between 4 wheels reduces their slipping, uses coupling of tires with a roadbed better and by that increases efficiency of accelerations.

Stability of a continence of a strip due to growth of the transferred side efforts improves.

Decrease in slipping promotes reduction of wear of tires. At the same time durability of tires in identical conditions is higher, than at tires on the leading axis of the all-wheel drive car of the same power.

For the faultless course of the car to use in a set of the tire of one manufacturer, a design, the size and a profile.

It is regular to control profile depth. Profile depth on forward wheels should not be significantly less than depth of a profile back (the maximum difference of 2 mm). The big difference leads to jamming of system of the drive.

If wear on forward wheels is more, than on back, it is necessary to trade their places.

Not to tow with a speed over 80 km/h. To carry out towage with the raised forward axis, only at the switched-off ignition or having taken out a safety lock 19. Otherwise the mode of the four-wheel drive will be activated.
