CONT

Part-time four-wheel drive (4WD) allows a vehicle to be driven in the two-wheel drive mode for ordinary highway and everyday driving (which reduces drivetrain friction and tire wear for improved fuel economy and tire life), and allows it to be switched to four-wheel drive when extra traction is needed (as when driving off-road, on gravel, snow, ice or mud).

DEF

[Système qui] achemine la puissance des roues arrière motrices aux roues avant par l'entremise d'une boîte de transfert. [...] la puissance est équitablement divisée entre les deux essieux. C'est donc dire que les roues avant et arrière ne peuvent tourner à des vitesses différentes.

OBS

Il est recommandé, pour des raisons de sécurité et de durabilité, de n'engager le dispositif que si le coefficient d'adhérence est bas (neige, boue, etc.) et non lorsque la chaussée est pavée et sèche.
