Controls in the instrument panel
Thumbwheel for adjusting interior brightness
Thumbwheel for headlamp levelling

A car with LED headlamps* has automatic head-
lamp levelling and therefore does not have the
thumbwheel for headlamp levelling.
Adjusting the interior brightness
The lamps inside the car come on differently
depending on the ignition position used.
The thumbwheel adjusts the brightness of display
lighting, control lighting, ambient lighting and
mood lighting.
Headlamp levelling
The load in the car changes the vertical align-
ment of the headlamp beam, which could dazzle
oncoming motorists. Avoid this by adjusting the
LED (Light Emitting Diode)

height of the beam. Lower the beam if the car is
heavily laden.
1. Leave the engine running, or have the car's
electrical system in ignition position I.
2. Roll the thumbwheel up/down to raise/lower
beam alignment.
The position in which the thumbwheel should be
set for a number of load cases is shown below.
