glance over your shoulder before
changing lanes.
The passenger side mirror is convex

Heated Front Seats
{Warning
If you cannot feel temperature
change or pain to the skin, the
seat heater may cause burns. To
reduce the risk of burns, people
with such a condition should use
care when using the seat heater,
especially for long periods of
time. Do not place anything on
the seat that insulates against
heat, such as a blanket, cushion,
cover, or similar item. This may
cause the seat heater to
overheat. An overheated seat
heater may cause a burn or may
damage the seat.
