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 economy 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 (0 kms
per liter).
An underinf 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.

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

Visually check the tires. If a tire
looks low, use a gauge to check its
pressure (see page ).

In cold weather, turn of f all
electrical accessories to reduce
the drain on the battery.
Press the clutch pedal down all the
way. The START (III) position
does not f unction unless the clutch
pedal is pressed.
Make sure the shif t lever is in
Park. Press on the brake pedal.Without touching the accelerator
pedal, turn the ignition key to the
START (III) position. Do not hold
the key in the START (III)
position f or more than 15 seconds
at a time. If the engine does not
start right away, pause for at least
10 seconds bef ore trying again.

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.On vehicles with 6-speed manual
transmission, the lockout system
prevents you f rom shif ting directly
from any forward gear to reverse
while the vehicle is moving at a
certain speed (see page ).
When shif ting up or down, make
sure you push the clutch pedal down
all the way, shif t 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 cancause your clutch to wear out f aster.
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.’’

The engine can be damaged if
you inadvertently downshif t into the
wrong gear (f or example, going f romthird gear at high rpms to second gear
instead of upshif ting to f ourth gear; theengine speed limiter will not work in thissituation).

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.
Drive in the highest gear that lets
the engine run and accelerate
smoothly. This will give you good
f uel economy and ef f ective
emissions control. The f ollowing
shif t points are recommended:

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.
Your vehicle has a rev limit indicator
to show you when the engine speed
is near the tachometer’s red zone
(see page ).If you are still unable to shif t to
reverse, apply the parking brake,
and turn the ignition key to the
ACCESSORY (I) or LOCK (0)
position.
With the clutch pedal still pressed,
start the engine.
Press the clutch pedal, and shif t to
reverse.
If you need to use this procedure to
shif t to reverse, your vehicle may be
developing a problem. Have the
vehicle checked by your dealer.
The manual transmission has a
lockout so you cannot accidentally
shif t f rom any f orward gear to
reverse while the vehicle is moving
at a certain speed. If you cannot shif t
to reverse when the vehicle is
stopped, do the f ollowing:
With the clutch pedal pressed,
move the shift lever to the first/
second gear side of the neutral
gate, then shif t to reverse.
