Warning!G
A driver’s attention to the road and traffic
conditions 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 44 feet
(approximately 14 m) every second.
