If you need more power for passing, and you’re:
Going less than 35 mph (55 kmk), push the
accelerator pedal about halfway down.
Going about 35 mph (55 kmh) or more, push the
accelerator all the way down.
The transaxle will shift down to the next gear and
have more power.
.NOTICE:
If your vehicle seems to start up rather slowly, or
if it doesn’t seem to shift gears as you accelerate,
something may be wrong with
a transaxle system
sensor..
If you drive very far that way, your
vehicle can be damaged.
So if this happens, have
your vehicle serviced right
away. Until then, you
can use SECOND
(2) when you are driving less
than
35 mph (55 km/h) and,OVERDRIVE (a)
for higher speeds.-
THIRD (3): This position is also. used for normal
driving, however, it offers more power and lower fuel
economy than
OVERDRIVE (0).
Here are examples for using THIRD (3) instead of
OVERDRIVE (0):
When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
. When going down a steep hill.
SECOND (2): This position gives you more power. You
can use SECOND (2) on hills. It ,can help control your
speed as you go down steep mountain roads, but then
you wbuld
also want to use your brakes off and on.

With the digital and analog cluster, you can go back and
forth from English (miles) to metric (kilometers) by
pressing this button.
Speedometer ar Odometer
The speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour
(km/h). The
odometer shows how far your vehicle has been driven,
in either miles (used in the United States) or kilometers
(used in Canada).
You may wonder what happens if a vehicle has to have a
new odometer installed. The new one may read the
correct mileage. This is because your vehicle’s computer
has stored the mileage in memory.

this
happens, the engine’s fuel supply is shut off. When the
vehicle speed slows, the fuel supply will come on again.

I NOTICE:
Do not operate the engine with the tachometer in
the red area or engine damage may occur.
Engine Speed Limiter
This feature prevents the engine from operating at too
many revolutions per minute (rpm). When the engine’s
rpm are critically high, the fuel supply to the engine is shu\
t
off. When the engine speed slows, the fuel supply will
come on again.
This helps prevent damage to the engine. This part describes the warning lights and gages that
may be on
your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be
or is a
problem with one of your vehicle’s functions.
As you
will see in the details
on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they’re working.
If you are
familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages and
warning lights work together to let you know when
there’s a problem with your vehicle.

Analog Cluster
This gage shows the
engine coolant
temperature. If the gage
pointer moves into the red area, the engine is too hot.
That reading means the same thing as the warning
light
-- the engine coolant
has overheated.
In the
section “Problems on the
Road,” this manual
explains what to do. See
“Engine Overheating” in
the Index.
Malfunction Indicator Lamp
(Service Engine Soon Light)
Your vehicle is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
control systems. SERVICE
ENGINE
SOON
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping to produce a cleaner
environment. The
SERVICE ENGINE SOON light
comes on and a chime will sound to indicate that there is
a problem and service is required. Malfunctions often
will be indicated by the system before
any problem is
apparent. This may prevent more serious damage
to
your vehicle. This system is also designed to assist your
service technician in correctly diagnosing
any
malfunction.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work
as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running.
If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
0 Light Flashing -- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis and service may be required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
Avoiding hard accelerations.
Avoiding steep uphill grades.
0 If you are towing a trailer, reduce the amount of
cargo being hauled
as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light
Is On Steady’’ following.
If the light continues to flash, when it is safe to do
so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least
10 seconds and restart the
engine. If the light remains
on steady, see “If the Light
Is On Steady’’ following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.

Downloaded from www.Manualslib.com manuals search engine If the Light Is On Steady Have you recentIy changed brands of fuel?
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If
so, reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine if the fuel
cap has been left
off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed should turn the light
off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly.
It
will take a few driving trips to turn the light off. If
so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your \
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may
go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use.
It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn
off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical
or electrical
problems that may have developed.
