µ
Each year, many children are injured
or killed in vehicle crashes because
they are either unrestrained or not
properly restrained. In f act, vehicle
accidents are the number one cause
of death of children ages 12 and
under.
To reduce the number of child
deaths and injuries, every state and
Canadian province requires that
inf ants and children be restrained
whenever they ride in a vehicle.
(See page
.)
(See page
.) We strongly recommend that you do
not carry any child in this car.
One reason is that your car does not
have a back seat, and accident
statistics show that a child of any
size or age is saf er when they are
properly restrained in the back seat
of a vehicle.
In addition, your car has a passenger’s
airbag which poses serious risks to
children particularly inf ants and
small children.

Any child too small for a seat
belt should be properly
restrained in a child seat. A

This section covers how to set up the
system controls f or ventilation,
heating, cooling, dehumidif ying, and
def rosting.
The engine must be running f or the
heater and air conditioning to
generate hot and cold air. The heater
uses engine coolant to warm the air.
If the engine is cold, it will be several
minutes bef ore you f eel warm air
coming from the system.
The air conditioning does not rely on
engine temperature.
You can adjust the direction of the
air coming from the vents on both
sides of the instrument panel and at
the corner of the dashboard on the
passenger’s side. To adjust the air
flow up and down, move the tab in
the center of each vent up and down.
To adjust it lef t and right, turn the
dial under each vent lef t and right. You can shut off the air flow from
each vent by turning the dial all the
way toward the mark until it
clicks.

µCheck your tires
f requently f or wear and proper
pressure. Both are important in
preventing ‘‘hydroplaning’’ (loss of
traction on a wet surface). In the
winter, mount snow tires on all f our
wheels f or the best handling.
Watch road conditions caref ully,
they can change f rom moment to
moment. Wet leaves can be as slip-
pery as ice. ‘‘Clear’’ roads can have
patches of ice. Driving conditions
can be very hazardous when the
outside temperature is near f reezing.
The road surf ace can become
covered with areas of water puddles
mixed with areas of ice, so your
traction can change without warning.
Be caref ul when downshif ting. If
traction is low, you can lock up the
drive wheels f or a moment and cause
askid. Be very cautious when passing, or
beingpassedbyothercars.The
spray f rom large cars reduces your
visibility, and the wind buf f eting can
cause you to lose control.Your car is not designed to tow a
trailer. Attempting to do so can void
your warranties.
