Shifting the 4 or 5 Speed
The fully synchronized manual trans- mission is very easy to shift up or
down. When you slow down for
traffic, steep hills, or corners, shift
to a lower gear before the engine starts to labor. When descendingsteep grades, select a lower gear to
help maintain a safe speed and toprevent the brakes from overheat-

ing.

When shifting, depress the clutch pedal fully, shift gears and then release the clutch gradually. Do not speed-shift; allow time for the
gears to synchronize.
To prevent grinding the gears when shifting into reverse, hold the clutch pedal depressed briefly before shifting, or shift the lever into one of the forward gears before selecting reverse.
On 5 speed transmissions, a safety lockout prevents accidentalshifting straight from 5th to Reverse.
Avoid rapid acceleration or sudden deceleration when either or both driving wheels are on a slippery surface. Decreased traction
could cause loss of directional control.

Clutch Pedal Adjustment
Clutch pedal free travel must be adjusted periodically to
compensate for lining wear. There should be approximately 25 mm (1 in) of pedal free travel. If not, or if the clutch seems to slip or
you have difficulty shifting, have your dealer check the clutch adjustment.
CAUTION:
Do not drive with your foot on the clutch pedal as this will cause
premature wear of clutch components.
Do not shift into reverse while the car is moving. Driving with the clutch pedal free travel improperly adjusted can
cause premature wear of the clutch components.

Maximum Allowable Speeds

The speeds shown below are the maximum at which the car can be driven or downshifted in each gear without over-revving the engine.ProCarManuals.comMain Menu s t

Shifting the Automatic
The automatic transmission shift lever has a locking mechanism to prevent accidental shifting into Reverse (R), Park (P) or 2nd (2). Also,
an Automatic Shift Lock prevents you from shifting out of Park
unless the brake pedal is already depressed and the ignition switch is
in the II position.
Push the button on the shift handle to shift into 2nd, Reverse or
Park; depress the brake pedal and then push the button on the shift
handle to shift out of Park. : Depress the brake pedal first
and push the button, then shift.
: Push the button, then shift.
: Shift as desired.

Neutral.

4. Return the key to the ignition switch, depress the brake pedaland restart the engine.

NOTE:
If you encounter any problem shifting out of Park, have your
authorized Honda dealer check the system as soon as possible.ProCarManuals.comMain Menu s t

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 D4, D3, 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 D4, D3, 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
D4-4th
Use the D4 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.

D3-3rd

Use of D3 will allow the transmission to start off in 1st and shift
automatically to 2nd and 3rd. Use D3 when climbing grades to
prevent the transmission from "hunting" between 3rd and 4th gear;
or when increased braking is needed.
NOTE: 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 D4 and D3 ranges.

2-2nd Use 2nd gear for increased engine braking when driving downhill,
and increased power when driving uphill; also for driving on slippery roads, and freeing the car from mud or sand, where 1st gear could provide too much power and cause skidding or wheelspin. The
maximum recommended speed in 2nd gear is:
62 mph (100 km/h)

R-Reverse

CAUTION:

Shift into or out of reverse only after the car has come to a
complete stop; the transmission may be damaged if you shift
while the car is moving.

P-Park
CAUTION:

Use this position when starting the engine, or when parking. Shift
into Park only when the car is COMPLETELY stopped.

N-Neutral
Use when starting the engine or during prolonged idling in traffic.

Engine Oil and Filter

Checking
Check the engine oil a couple of minutes after shutting the engine
off, with the car parked on level ground. Remove the dipstick and wipe it clean. Re-insert it all the way down, then pull it out and read
the level. The level should be between the upper and lower marks.

DIPSTICK

FILLER CAP

Adding
If the level has dropped close to the lower mark, add oil until it is
even with the upper mark.
1.Turn the oil filler cap counterclockwise to remove. Add oil, then check the level again. Do not overfill.
2. Reinstall the cap and twist clockwise until it stops.

CAUTION:
Be sure the oil filler cap is correctly replaced before starting the

engine.
Engine oil is a major factor affecting the performance and
service life of the engine, you should use only a premium quality
detergent oil labeled SG grade.
Some oil labels may also include additional designations of quality
such as CC or CD. However, these are acceptable only when used

together with SG.

LOOK FOR THIS LABEL ON THE

OIL CONTAINER
Use the proper viscosity oil for the
climate in which you drive:

Fuel Efficient Oil For the best fuel economy from your car, it is recommended that
you use a fuel efficient SG grade oil. This oil is usually identified by
the words such as: "Energy Conserving II," "Gas Saving," and "Fuel Saving," etc.
Changing Oil and Filter
Engine oil and filter should be changed together every 6 months or
7,500 miles (12,000 km), whichever comes first. The filter is located
on the engine block, below the intake manifold. A special "cap
type" oil filter wrench is required (available from your Honda dealer). Use only a genuine Honda filter or its equivalent.

CAUTION:

The oil filter cannot easily be removed from above the engine. For
this reason it is recommended that the oil filter change be done by a skilled mechanic.
1. Start the car to warm up the engine, then shut it off.
2. Remove the engine oil filler cap and drain bolt, and drain the oil.
A warmed-up engine and the oil in
it are hot; be careful not to burn yourself.
3. Remove the oil filter and let the remaining oil drain out.
4. Install a new filter according to
the instructions on or with the

filter.

5. Reinstall the drain bolt with a new washer and tighten it securely.Refill the engine with the recom-
mended oil, to the upper mark on

the dipstick.

NOTE:Please dispose of used motor oil in a manner that is compatible with
the environment. We suggest you take it in a sealed container to

your local service station for reclamation. Do not throw it in the

trash or pour it on the ground.

CAUTION:

Used motor oil may cause skin cancer if repeatedly left in contact
with the skin for prolonged periods. Although this is unlikely
unless you handle used oil on a daily basis, it is still advisable to
thoroughly wash your hands with soap and water as soon as possible after handling used oil.ProCarManuals.comMain Menu s t
