Gasoline
For proper operation of your car's emission controls, your engine is
designed to use unleaded fuel only.

CAUTION:

Using leaded or even low-lead gasoline could damage some of your
emission controls, and also void their coverage under the emission
controls warranty.
Use gasoline from pumps labeled unleaded, with a pump octane
number of 86 or higher. The pump octane number is an average of
the Research (R) octane and Motor (M) octane numbers. Use of a
lower octane gasoline can cause persistent, heavy "SPARK
KNOCK" (a metallic rapping noise), which can lead to engine damage

if severe.
CAUTION:
If you notice steady spark knock while holding a steady speed on a
level road, try changing brands of gasoline. If the spark knock persists, consult your Honda dealer. Failure to do so is considered
misuse, and misuse is not covered under the New Car Warranty.
Occasionally you may notice light spark knock while accelerating or
driving up hills. This is no cause for concern, it simply means your engine is running at its most economical.
Gasoline Containing Alcohol
If you decide to use a gasoline containing alcohol ("gasohol"), be
sure its octane rating is at least as high as that recommended for
unleaded gasoline. There are two types of "gasohol": that
containing ethanol, and that containing methanol. Do not use
gasohol that contains more than 10% ethanol. Do not use gasoline
containing methanol (methyl or wood alcohol) that does not also contain cosolvents and corrosion inhibitors for methanol. Never use
gasoline containing more than 5% methanol, even if it hascosolvents and corrosion inhibitors.

Ignition Switch
The combined ignition switch/anti-theft lock is located on the right side of the steering column and has four positions:
0-LOCK position: The key can be removed or inserted in thisposition. To remove the key, push it in at position I, then turn it to
0 and pull it out. When the key is removed, the steering column

will lock.

NOTE:

On cars equipped with automatic transmissions, the transmission
must be in Park before pushing and turning the key to the O-LOCK position.
Never turn the ignition switch to the lock position or remove the
key while the car is in motion; the steering wheel can lock causing
a loss of directional control, and an accident could result. I-ACCESSORY position: In this position, the accessory circuit is

on, but the ignition circuit is off.
If the key is difficult to turn from the 0 to the I position, turn the

steering wheel slightly to relieve pressure on the lock.
II-ON position: This Is the normal running position.
III-START position: The starter will engage when the key is
turned to this position.
To remind you to remove the ignition key when leaving your car, a beeper will sound if the key is still in the ignition when you open the
driver's door. The beeper system is deactivated when you turn the ignition to 0 (Lock) and fully remove the key.ProCarManuals.comMain Menu t s

Safety Items
Before driving away, check that: The doors are closed properly. The mirrors are properly adjusted, and the windows clean.
The driver and passengers are wearing properly adjusted seat
belts.
The head restraints are properly adjusted.
The warning and indicator lights are operating properly.
The brake pedal feels normal.
All luggage and cargo is secured.
Nothing is interfering with the driver's feet or blocking vision to

the rear.

While driving remember to: Always drive defensively; expect the unexpected. Reduce your speed during night hours and bad weather.
Follow at a safe distance; don't tailgate.
Get off the highway when you are tired; stop and take a rest.
When stopping for repairs: Park the car well off the road.
Turn on the hazard warning flasher. Use flares or other warning devices to warn other motorists.
After parking your car: Apply the parking brake and shift to first gear if equipped withmanual transmission, or PARK on automatic transmission

equipped cars.
Make sure the windows are closed and all doors are locked.
If parked on a hill:
Turn the front wheels away from the curb if facing uphill.

Operating Tips

For smoother operation, apply the brakes when shifting from
Neutral or Park to a forward or reverse gear.
When parking: bring the car to a stop with the foot brake, hold the brake on and shift into Park, set the hand brake and then turn off
the engine.

NOTE:

Your 4 speed automatic transmission is equipped with a torque
converter lock-up clutch. Because of this, you may notice what
feels like an extra shift as the clutch engages.
CAUTION: Shift into P only after the car has come to a complete stop.
Shift into or out of R only after the car has come to a complete

stop.

Do not "rev-up" the engine when the brake is on and the shift
lever is in D, S, 2 or R.
When stopped on a hill, use the brakes to hold your position, not the accelerator pedal.Do not shift from N or P into D, S, 2 or R when the engine is
above idle speed. Before shifting into gear, make sure your foot
is firmly on the brake pedal. Do not rest your hand on the shift lever or push the shift button
while driving.

Driving Technique

D-4th
Use the D range for normal in-town and highway driving. The car
will start off in 1st and shift automatically to 2nd, 3rd, and 4th. The
further down you push the accelerator, the later the transmission will shift and the faster the car will accelerate.

S3/S4

The "S" shift selector range changes the shift points under part
throttle acceleration, allowing the transmission to stay in each lower
gear for a longer period before automatically upshifting. With the shift selector in the "S" range, the "S3" indicator light in the dashpanel will come on and the transmission will shift from 1st to 2nd
and 3rd but not 4th. This is especially useful when climbing or
descending grades. While driving in the "S" range, the car's performance is improved but fuel economy is reduced.
Shifting the Automatic (cont'd)ProCarManuals.comMain Menu t s

While driving in the "S" range, you can select 4th gear by pushing
the "S4"
switch. Depending upon vehicle speed and throttle pedal
position, the transmission will shift to 4th gear when the switch is
pressed; the "S4" indicator light in the instrument panel will come
on. Pushing the "S4" switch again will cause the transmission to
downshift to 3rd gear In the "S3" mode. The "S4" indicator light in
the instrument panel will go out, and the "S3" light on the instrument panel will come on.
If the shift lever is moved to any other driving range, the "S4"
switch will be cancelled automatically.

NOTE:
In both the D and S modes, the transmission holds in
2nd while
you are
stopped in gear. When you start moving again, the
transmission shifts to 1st, then 2nd and so on. If rapid acceleration is necessary, depress the accelerator to the
floor; the transmission will automatically shift down according to
load and engine speed. This applies to both D and S ranges.

Towing a Trailer (cont'd)

Hitches

Use only a hitch recommended by your Honda dealer. The hitch

should be bolted securely to the car and installed by a qualified

technician. Do not use a hitch designed for temporary installation
and never use one that attaches only to the bumper.
Trailer Brakes and safety chains
The Honda Automobile Division recommends that trailers equippedwith brakes, should conform to any applicable federal and stateregulations, When using a trailer equipped with electric brakes, a
trailer brake controller that connects to the car's electrical system is recommended. Installing a brake controller that connects to the car's
brake hydraulic system could result in brake fluid contamination or
leaks, A safety chain must always be used between the car and the
trailer. Leave sufficient slack in the chain so that it does not bind in
sharp turns. The chain should cross under the trailer tongue to prevent the tongue from dropping to the ground.

Tires
Make sure your car's are properly inflated. Adjust tire pressure

to the recommended tire pressure indicated on the label attached to
the edge of the driver's door.The trailer tires should be of the proper size, load rating and inflated to the pressure recommended
by the trailer manufacturer.
Trailer Lights
Trailer light must comply with federal, state and local regulations. See your local recreation vehicle dealer or rental agency for the

correct type of lighting and wiring for your trailer, Check for correct
operation of the turn signals and stop lights each time you hitch up.

CAUTION:

Connections to your car's electrical system should be made by
your Honda dealer or a qualified electrician.Improper installation

may damage your vehicle's electrical system and cause a

malfunction of the lights.
ProCarManuals.comMain Menu t s

CAUTION:
Before starting out, check the operation of the lights and all car/
trailer connections. After driving a short distance, stop and
recheck the lights and connections.
Reversing is difficult and requires practice. While backing-up,
the trailer may pivot off-course. To correct for this, grip the bottom of the steering wheel and move your hand to the left to
move the trailer to the left, or to the right to move the trailer to
the right. Turn the steering wheel a little at a time, and keep the
speed very low. Have someon e guide you when backing.

To help
prevent overheating of the brakes, shift into a lower
gear to make use of engine braking before descending steep or
long grades. Do not make sudden downshifts. Pay strict attention to the coolant temperature gauge when
going up hills. Because of the added load of the trailer, your car's
engine may overheat on hot days. Turning off the air conditioner
will reduce the load on the cooling system.
On cars equipped with automatic transmission. —Do not hold the car stationary on an incline by using the accelerator pedal; this can cause the transmission fluid tooverheat. Instead, use the handbrake or footbrake.
—When towing trailers, avoid high transmission fluid temperatures (caused by the transmission frequently shiftingbetween 3rd and 4th gears) by driving in S3.

NOTE:

Be sure to check state and local laws concerning maximum speed or

other driving restrictions for cars towing trailers. If you are driving
across several states, check each state's requirements before

leaving home, because restrictions may vary.

Parking with a Trailer

Whenever parking your car on an incline with a trailer attached, first
place and seat chocks at each wheel of the car and trailer. This is in

addition to the normal parking preparations of firmly applying the parking brake and placing the transmission in first or reverse
(manual transmission) or P (automatic transmission).

CAUTION:
Parking on an incline is not recommended and should be done only
if it cannot be avoided. Follow all precautions mentioned above
and turn the wheels to point towards a curb if facing downhill,
away from a curb if facing uphill. When leaving an inclined parking place, move the car slightly to unseat the chocks. Then while
keeping the foot brakes firmly applied, have an assistant remove
the chocks.ProCarManuals.comMain Menu t s

Check the following items at each fuel stop:

1. Engine oil level.

2. Radiator coolant level.
Check the following items periodically: 1. Brakes: for braking efficiency, brake pedal travel and hydraulic fluid level.
2. Lights: for operation of headlights, taillights, side marker lights, stoplights, turn signals and back-up lights.
3. Tires: for correct pressures (including spare); inspect for cuts and uneven or excessive wear. Rotate every 7,500 miles (12,000 km)
in the pattern shown on page 107.
4. Steering: for excessive play or vibration while driving. 5. Exhaust system: for leaks or loose mounts.
6. Wipers: for operation of windshield wipers and washer, and condition of wiper blades.
7. Seat belts: for condition of fabric and buckles, and operation of the restraint mechanism.
