Engine oil viscosity
Measurement for the inner friction (vis-

oil can tolerate without becoming thin,
or the lower the temperature it can tol-
erate without becoming viscous, the
better the viscosity.

multifunction display that informs the
driver when the next vehicle mainte-

engine temperature, oil level, vehicle
speed, engine speed, distance driven
and the time elapsed since your last
maintenance service, and calls for the
next maintenance service accordingly.
Gear range

the automatic transmission for shifting.
The automatic gear shifting process
can be adapted to specific operating

KEYLESS-GO*
System for entering and operating the

Kickdown
Depressing the accelerator past the

acceleration needs.
