You can manually select various
f unctions of the Climate Control
system when it is in FULL AUTO.
All other f eatures remain auto-
matically controlled. Making any
manual selection causes the word
FULL to go out.
When you turn the A/C of f , the sys-
tem cannot regulate the inside tem-
perature if you set the dial below the
outside temperature. With the A/C
on, use the temperature control dial
to adjust the temperature of the air
flow to a comfortable setting.With the A/C in economy mode, you
will see A/C ECON in the system’s
display. Use this mode to get better
f uel economy.
Press the A/C button to operate the
air conditioning. Each time you press
the A/C button, the display shows
the mode: A/C ECON, A/C OFF, or
A/C ON.
In this mode, you may f eel a slight re-
duction in cooling ef f iciency. If you
want more cooling, select A/C ON or
FULL AUTO.

A cold engine uses more f uel than a
warm engine. It is not necessary to
‘‘warm-up’’ a cold engine by letting it
idle f or a long time. You can drive
away in about a minute, no matter
how cold it is outside. The engine
will warm up f aster, and you get
better f uel economy. To cut down on
the number of ‘‘cold starts,’’ try to
combine several short trips into one.
You can improve f uel economy by
driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more f uel.
Always drive in the highest gear that
allows the engine to run and acceler-
ate smoothly.
An important part of that mainte-
nance is the (see page ). For
example, an underinf lated tire
causes more ‘‘rolling resistance,’’
which uses f uel. It also wears out
f aster, so check the tire pressure at
least monthly. The air conditioning puts an extra
load on the engine which makes it
usemorefuel.Turnoff theA/Cor
set the climate control to a higher
temperature to cut down on air
conditioning use. Use the flow-
through ventilation when the outside
air temperature is moderate.
The condition of your car and your
driving habits are the two most
important things that affect the fuel
mileage you get.
Always maintain your car according
to the maintenance schedule. This
will keep it in top operating condition.
In winter, the build-up of snow on
your car’s underside adds weight and
rolling resistance. Frequent cleaning
helps your f uel mileage and reduces
thechanceof corrosion.
Depending on traf f ic conditions, try
to maintain a constant speed. Every
time you slow down and speed up,
your car uses extra f uel. Use the
cruise control, when appropriate, to
increase f uel economy.

µµBeing able to see
clearly in all directions and being
visible to other drivers are important
in all weather conditions. This is
more dif f icult in bad weather. To be
seen more clearly during daylight
hours, turn on your headlights. Check 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
beingpassedbyothervehicles.The
spray f rom large vehicles reduces
your visibility, and the wind buf f eting
can cause you to lose control.
Inspect your windshield wipers and
washers f requently. Keep the wind-
shield washer reservoir f ull of the
proper f luid. Have the windshield
wiper blades replaced if they start to
streak the windshield or leave parts
unwiped. Use the def roster and air
conditioning to keep the windows
f rom f ogging up on the inside (see
pages and ).

The added weight, length, and
height of a trailer will af f ect your
vehicle’s handling and perf ormance,
so driving with a trailer requires
some special driving skills and
techniques.Maketurnsmoreslowlyandwider
than normal. The trailer tracks a
smaller arc than your vehicle, and it
canhitorrunoversomethingthe
vehicle misses. Allow more time and
distance f or braking. Do not brake or
turn suddenly as this could cause the
trailer to jackknif e or turn over.If you must stop when f acing uphill,
use the f oot brake or parking brake.
Do not try to hold the vehicle in
place by pressing on the accelerator,
as this can cause the automatic
transmission to overheat.
When driving down hills, reduce
your speed and shif t down to 2nd
gear. Do not ‘‘ride’’ the brakes, and
remember it will take longer to slow

discussed below.
When climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, turn the air

necessary, pull to the side of the
road to let the engine cool.
If the automatic transmission shifts

Drive slower than normal in all
driving situations, and obey posted
speed limits f or vehicles with trailers.
Use the D position when towing a
trailer on level roads. D is the
proper shif t lever position to use
when towing a trailer in hilly terrain.
