The f ollowing f actors can lower your
vehicle’s f uel economy:
Aggressive driving (hard
acceleration and braking)
Excessive idling, accelerating and
braking in stop-and-go traf f ic
Cold engine operation (engines
aremoreefficientwhenwarmed
up)
Driving with a heavy load or the
air conditioner running
Improperly inf lated tires
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: 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.
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.
Combine several short trips into
one. A warmed-up engine is more
f uel ef f icient than a cold one. 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.

Apply the parking brake.
In cold weather, turn of f all
electrical accessories to reduce
the drain on the battery.
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.If the engine does not start within
15 seconds, or starts but stalls
right away, repeat step 4 with the
accelerator pedal pressed halfway
down. If the engine starts, release
pressure on the accelerator pedal
so the engine does not race.
If the engine fails to start, press
the accelerator pedal all the way
down, and hold it there while
starting to clear flooding. If the
engine still does not start, return
to step 5.

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
more inf ormation, see page .
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.

µµThis position mechani-
cally locks the transmission. Use
Park whenever you are turning of f or
starting the engine. To shif t out of
Park, you must press on the brake
pedal and have your f oot of f the
accelerator pedal. Pull the shif t lever
towards you, then move it out of
Park.
If you have done all of the above and
still cannot move the lever out of
Park, see on
page .
You must also pull the shif t lever
towards you to shift into Park. To
avoid transmission damage, come to
a complete stop bef ore shif ting into
Park. The shif t lever must be in Park
for you to remove the key from the
ignition switch. Press the brake
pedal and pull the shif t lever towards
you to shif t f rom Park to reverse. To
shif t f rom reverse to neutral, come
to a complete stop, and then shif t.

Press the D3 switch on the end of
the shif t lever to turn this mode on
or of f ; the D3 indicator comes on
whenever D3 is selected.
TheD3switchcanbeoperatedonly
when the ignition switch is in the ON
(II) position and the shif t lever is in
the D position.
Use this position f or
your normal driving. The
transmission automatically selects a
suitable gear (1 through 5) f or your
speed and acceleration. You may
notice the transmission shif ting up at
higher engine speeds when the
engine is cold. This helps the engine
warm up f aster.
Af ter you stop in D, 2, 1, N, or R
position with the ignition switch in
the ACCESSORY (I) position f or an
extended period, you may not be
able to move the shift lever from
neutral to reverse or Park. In this
case, press the brake pedal, and turn
the ignition switch to the ON (II)
position, then shif t out of neutral. Use neutral if you
need to restart a stalled engine, or if
it is necessary to stop brief ly with
the engine idling. Shif t to the Park
position if you need to leave your
vehicle for any reason. Press on the
brake pedal when you are moving
the shift lever from neutral to
another gear.

µTo shif t to second,
pull the shif t lever towards you, then
shif t to the lower gear. This position
locks the transmission in second
gear. It does not downshif t to f irst
gear when you come to a stop.
Use second gear:
For more power when climbing.
To increase engine braking when
going down steep hills.
For starting out on a slippery
surf ace or in deep snow.
To help reduce wheel spin.
When driving downhill with a
trailer.
When towing a trailer on level roads
under normal driving conditions, do
not use D3. This will increase the
automatic transmission f luid
temperature and may cause
overheating.
Shif ting out of the D position will
cancel D3, and cause the D3
indicator to go out. Selecting the D
position again will resume D3, and
the indicator will come on.
Turning the ignition switch to the
LOCK (0) position turns D3 of f . To
use D3 when you restart the engine,
select the D position, and press the
D3 switch again.
TheD3indicatoralsocomesonfora
f ew seconds when you turn the
ignition switch to the ON (II)
position.
When D3 is on, the transmission
selects only the f irst three gears.
Use D3 f or engine braking when
going down a steep hill.

µTo shif t f rom second to
first, pull the shift lever towards you,
then shif t to the lower gear. This
position locks the transmission in
f irst gear. By upshif ting and
downshif ting through 1, 2, and D,
you can operate the transmission
much like a manual transmission
without a clutch pedal.
If you shif t into f irst position when
the vehicle speed is above 28 mph
(45 km/h), the transmission shif ts
into second gear first to avoid
sudden engine braking. 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.
This allows you to move the shif t
lever out of Park if the normal
method of pushing on the brake
pedal and pulling the shif t lever does
not work.
Set the parking brake.
Make sure the ignition switch is in
the LOCK (0) position.
