329 Technical terms
Tire speed rating
Part of tire designation; indicates the
speed range for which a tire is ap-
proved.
Traction
Force exerted by the vehicle on the
road via the tires.
Transfer case
Speed of rotation/torque converter
that works together with the ->auto-
matic transmission. In the LOW mode
off-road position, the transfer case de-
creases the output rotational speed of
the ->automatic transmission by ap-
proximately half. This results in a corre-
sponding increase of torque on the
drive axles.
The vehicle then has nearly double the
driving force but drives only approxi-
mately half as fast.VIN
(V
ehicle I
dentification N
umber)
The number set by the manufacturer
and placed on the body to uniquely
identify each vehicle produced.
Voice control system*
Voice control system for car phones,
portable cell phones and audio sys-
tems (radio, CD, etc.).
