Remove the dipstick again and
check the level. It should be
between the upper and lower
marks.Look at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, see
on page f or
inf ormation on adding the proper
coolant.
If it is near or below the lower mark,
see on page . Refer to

The condition of your vehicle and
your driving habits are the two most
important things that affect the fuel
mileage you get.
Always maintain your vehicle accord-
ing to the maintenance schedule.
This will keep it in top operating
condition.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.
Depending on traf f ic conditions, try
to maintain a constant speed. Every
time you slow down and speed up,
your vehicle uses extra f uel. Use the
cruise control, when appropriate, to
increase f uel economy.
The air conditioning puts an extra
load on the engine which makes it
usemorefuel.Turnoff theA/Cto
cut down on air conditioning use.
Use the f low-through ventilation
when the outside air temperature is
moderate.
In winter, the build-up of snow on
your vehicle’s underside adds weight
and rolling resistance. Frequent
cleaning helps your f uel mileage and
reduces the chance of corrosion. 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. 259

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. If the engine
does not start right away, do not
hold the key in START (III) f or
more than 15 seconds at a time.
Pause f or 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 half-way
down. If the engine starts, release
pressure on the accelerator pedal
so the engine does not race.If the engine still does not start,
press the accelerator pedal all the
way down and hold it there while
starting in order to clear f looding.
As bef ore, keep the ignition key in
the START (III) position f or no
more than 15 seconds. Return to
step 5 if the engine does not start.
If it starts, lif t your f oot of f the
accelerator pedal so the engine
does not race.
An engine is harder to start in cold
weather. The thinner air f ound at
high altitude above 8,000 f eet (2,400
meters) adds to the problem.
Use the f ollowing procedure: Turn of f all electrical accessories
to reduce the drain on the battery. Push the accelerator pedal half-
way to the f loor and hold it there
while starting the engine. Do not
hold the ignition key in START
(III) f or more than 15 seconds.
When the engine starts, release
the accelerator pedal gradually as
the engine speeds up and smooths
out.
If the engine fails to start in step 2,
push the accelerator pedal to the
f loor and hold it there while you
try to start the engine for no more
than 15 seconds. If the engine
does not start, return to step 2.

The shif t lever has eight positions. It
must be in Park or Neutral to start
the engine. When you are stopped in
D,D,D,2,1,NorR,pressfirmly
on the brake pedal, and keep your
f oot of f the accelerator pedal. YoucannotshiftoutofParkwiththe
brake pedal depressed when the
ignition switch is in LOCK (0) or
ACCESSORY (I). This 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.
If you have done all of the above and
still cannot move the lever out of
Park, see Shif t Lock Release on page .
To avoid transmission damage, come
to a complete stop bef ore shif ting
into Park. The shif t lever must be in
Park bef ore you can remove the key
from the ignition switch. 215

To shif t to Reverse
f rom Park, see the explanation under
Park. To shif t to Reverse f rom
Neutral, come to a complete stop and
then shift. 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 Park posi-
tion if you need to leave the vehicle
f or any reason. Press on the brake pe-
dal when you are moving the shif t
lever from Neutral to another gear.
Use this position f or
your normal driving. The
transmission automatically selects a
suitable gear for your speed and
acceleration. You may notice the
transmission shif ting up at higher
speeds when the engine is cold. This
helps the engine warm up f aster.
Your car has a reverse lockout so
you cannot accidentally shif t to
Reverse from Neutral or any other
driving position when the vehicle
speed exceeds 7 9 mph (12 14
km/h).
If you cannot shif t to Reverse when
the car is stopped, press the brake
pedal and slowly shif t to Neutral, and
then to Reverse.
If there is a problem in the reverse
lockout system, or your vehicle’s
battery is disconnected or goes dead,
you cannot shif t to Reverse. (Ref er
to Shif t Lock Release on page ).

These positions
are similar to D , except when you
select the D position, only the f irst
f our gears are selected. When you
select D , only the f irst three gears
are selected. D can also keep the
transmission f rom cycling between
f ourth and f if th gears in stop-and-go
driving, and D can keep the
transmission f rom cycling between
third and f ourth gears. This position locks
the transmission in second gear. It
does not downshif t to f irst gear
when you come to a stop. Second
gives you more power when climbing,
and increased engine braking when
going down steep hills. Use second
gear when starting out on a slippery
surf ace or in deep snow. It will help
reduce wheelspin.
ForfasteraccelerationwheninD ,
D or D , you can get the
transmission to automatically
downshif t by pushing the accelerator
pedal to the f loor. The transmission
will shif t down one or two gears,
depending on your speed.
Use D to provide engine braking
when going down a steep hill. D
gives you more power and increased
engine braking.

µIf 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. Set the Parking brake.
With the lever in this
position, the transmission locks in
First gear.
If you shif t into First position when
the vehicle speed is above 31 mph
(50 km/h), the transmission shif ts
into Second gear f irst to avoid
sudden engine braking. This allows you to move the shif t
lever out of Park if the normal
method of pushing on the brake
pedal does not work. This procedure
is also used to release the Reverse
Lockout.
Make sure the key is in the
ignition switch LOCK (0) position.
To release the Reverse Lockout,
make sure the key is in the
ACCESSORY (I) position.
