The f ollowing f actors can lower your
vehicle’s f uel economy:
A properly maintained vehicle
maximizes f uel economy. Poor
maintenance can signif icantly reduce
f uel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the
inf ormation display (see
on page ).
For example: Rapid
acceleration, abrupt cornering,
and hard braking increase fuel
consumption.
Aerodynamic drag has a big ef f ect
on f uel mileage at speeds above 45
mph (75 km/h). Reduce your
speed and you reduce the drag.
Trailers, car top carriers, roof
racks and bike racks are also big
contributors to increased drag.
If your vehicle has a
manual transmission, you can
boost your f uel economy by up
shif ting as early as possible.
Idling
results in 0 miles per gallon.
An under-inf lated tire increases
‘‘rolling resistance,’’ which reduces
f uel economy.
It puts a heavier
load on the engine, increasing f uel
consumption.
In
particular, a build-up of snow or
mud on your vehicle’s underside
adds weight and rolling resistance.
Frequent cleaning helps your f uel
economy.

Fill the f uel tank until the nozzle automatically clicks of f .
Reset trip counter to zero.
Record the total gallons (liters) needed to ref ill.
Follow one of the simple calculations above.
The A/C
puts an extra load on the engine
which makes it use more f uel. Use
the f resh-air ventilation when
possible.
Combine several short trips into
one. A warmed-up engine is more
f uel ef f icient than a cold one.
Direct calculation is the
recommended source of inf ormation
about your actual f uel economy.
Using f requency of f ill-ups or taking
f uel gauge readings are NOT
accurate measures of f uel economy.

Youshoulddothefollowingchecks
and adjustments bef ore you drive
your vehicle.Make sure all windows, mirrors,
and outside lights are clean and
unobstructed. Remove f rost, snow,
or ice. Check that any items you may be
carrying are stored properly or
f astened down securely.
Fasten your seat belt. Check that
your passenger has f astened his or
her seat belt (see page ).
When you start the engine, check
the gauges and indicators in the
instrument panel (see page ).
Check the seat adjustment (see

Check the adjustment of the
inside and outside mirrors (see
page ).
Make sure the doors are securely
closed and locked.
Check that the hood is f ully closed.
Check that the trunk is f ully
closed.
Visually check the tires. If a tire

Apply the parking brake.
In cold weather, turn of f all
electrical accessories to reduce
the drain on the battery.
Push the clutch pedal down all the
way. The ENGINE START button
has no ef f ect unless the clutch
pedal is pressed.
Turn the ignition key to the ON
(II) position.
Without touching the accelerator
pedal, push the ENGINE START
button. Do not hold the ENGINE
START button for more than 15
seconds at a time. If the engine
does not start right away, pause
f or at least 10 seconds bef ore
trying again.If the engine fails to start, press
the accelerator pedal all the way
downandholdittherewhile
starting to clear flooding. If the
engine still does not start, return
to step 6.
If theenginedoesnotstartwithin
15 seconds, or starts but stalls
right away, repeat step 5 with the
accelerator pedal pressed halfway
down. If the engine starts, release
pressure on the accelerator pedal
so the engine does not race.

The engine is harder to start in cold
weather. Also, the thinner air f ound at
altitudes above 8,000 f eet (2,400
meters) adds to this problem.
T he immobilizer system protects your
vehicle f rom thef t. If an improperly-
coded key (or other device) is used, the
engine’s f uel system is disabled. For

The manual transmission is
synchronized in all f orward gears f or
smooth operation. It has a lockout so
you cannot shift directly from fifth to
reverse instead of sixth (see page). When shif ting up or down,
make sure you push the clutch pedal
down all the way, shift to the next
gear, and let the pedal up gradually.
When you are not shif ting, do not
rest your f oot on the clutch pedal.
This can cause your clutch to wear
out f aster. When slowing down, you can get
extra braking f rom the engine by
shifting to a lower gear. This extra
braking can help you maintain a safe
speed and prevent your brakes f rom
overheating while going down a
steep hill. Bef ore downshif ting,
make sure the engine speed will not
go into the tachometer’s red zone in
the lower gear.
Your vehicle is equipped with an
aluminum shif t lever. If you leave the
vehicle parked outside f or a long
time on a hot day, be caref ul bef ore
moving the shift lever. Because of
the heat, the shift lever may be
extremely hot. If the outside
temperature is low, the shif t lever
f eels cold.
Come to a full stop before you shift
into reverse. You can damage the
transmission by trying to shift into
reverse with the vehicle moving.
Push down the clutch pedal, and
pause f or a f ew seconds bef ore
shif ting into reverse, or shif t into one
of the f orward gears f or a moment.
This stops the gears so they won’t
‘‘grind.’’

Rapid slowing or speeding up
can cause loss of control on
slippery surfaces. If you crash,
you can be injured.
Use extra care when driving on

If you exceed the maximum speed
f or the gear you are in, the engine
speed will enter into the tachometer’s
red zone. If this occurs, you may f eel
the engine cut in and out. This is
caused by a limiter in the engine’s
computer controls. The engine will
run normally when you reduce the
rpm below the red zone.
Bef ore downshif ting, make sure the
engine will not go into the
tachometer’s red zone.With the clutch pedal pressed, move
theshiftlevertothereversesideof
the neutral gate. Then push the shift
lever down, and shift to reverse.

f uel economy and ef f ective
emissions control. The f ollowing

Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness
and reduces brake pad life. In
addition, f uel economy can be
reduced. It also keeps your brake
lights on all the time, conf using
drivers behind you.
Your vehicle is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. The anti-lock
brake system (ABS) helps you retain
steering control when braking very
hard.
Always use the parking brake when
you park your vehicle. Make sure
the parking brake is set f irmly, or
your vehicle may roll if it is parked
on an incline.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by taking your f oot of f the
accelerator and downshif ting to a
lower gear.
Make sure the convertible top and
the windows are closed.
Make sure the removable hardtop
is properly installed and the
windows are closed.
Make sure the parking brake is
f ully released bef ore driving away.
Driving with the parking brake
partially set can overheat or
damage the rear brakes.
If the vehicle is f acing downhill,
turn the front wheels toward the
curb, and put the transmission in
reverse gear.
If the vehicle is f acing uphill, turn
the front wheels away from the
curb, and put the transmission in
f irst gear.
Never park over dry leaves, tall
grass, or other f lammable materials. The hot three way
catalytic converter could cause
these materials to catch on fire.
Lock the doors.
Place any packages, valuables, etc.,
in the trunk or take them with you.
Turn of f the lights.
