Remote Vehicle Start
Your vehicle may have a remote starting feature that
starts the engine from outside of the vehicle.
If your vehicle has an automatic climate control system,
the climate control system will default to a heating or
cooling mode depending on the outside temperatures. If
your vehicle does not have an automatic climate control
system, the system will turn on at the setting the vehicle
was set to when the vehicle was last turned off.
If your vehicle has an automatic climate control system
and heated seats, the heated seats will turn on
during colder outside temperatures and will shut off
when the key is turned to ON/RUN. SeeHeated Seats
on page 1-5for more information.
The rear window defogger and heated mirrors, if your
vehicle has them, will turn on during colder outside
temperatures and will turn off when the key is turned to
ON/RUN.
Laws in some communities may restrict the use of
remote starters. For example, some laws may require a
person using the remote start to have the vehicle in
view when doing so. Check local regulations for
any requirements on remote starting of vehicles.

If your vehicle has the memory package, the outside
mirrors are able to perform the park tilt function. This
feature may be useful in allowing the driver to view the
curb when parallel parking. This feature will cause the
passenger’s and/or driver’s mirror to tilt to a preselected
position when the vehicle is in REVERSE (R).
The passenger’s and/or driver’s mirror will return to its
original position when the vehicle is shifted out of
REVERSE (R), or the ignition is turned off or to

information.

A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
The passenger’s side mirror may have convex glass. A
convex mirror’s surface is curved so more can be
seen from the driver’s seat.

climate control panel, to also turn the outside heated
mirrors on or off. The mirrors will heat to help clear fog
or frost from the surface of the mirror.
