Autosteer and its associated functions are particularly
unlikely to operate as intended when:
Autosteer is unable to accurately determine lane
markings. For example, lane markings are excessively
worn, have visible previous markings, have been
adjusted due to road construction, are changing
Tire performance is reduced in low ambient
temperatures, resulting in reduced grip and an increased
susceptibility to damage from impacts. Performance
tires (summer applications) have reduced traction in
ambient temperatures below 40º F (5º C), and are not
recommended in snow/ice conditions.
