Wa r n i n g !
A driver’s attention to the road must always be his /
her primary focus when driving. For your safety and the safety of others, selecting 
features through the multifunction steering wheel 
should only be done by the driver when traffic and 
road conditions permit it to be done safely. Bear in mind that at a speed of just 30 mph 
(approximately 50 km/h), your vehicle is covering 
a distance of approximately 50 feet (approximately 
14 m) every second.
