Knowing your vehicle
How car audio worksAM and FM radio signals are broadcast
from transmitter towers located around
your city. They are intercepted by the
radio antenna on your car. This signal is
then received by the radio and sent to
your car speakers.
When a strong radio signal has reached
your vehicle, the precise engineering of
your audio system ensures the best pos-
sible quality reproduction. However, in
some cases the signal coming to your
vehicle may not be strong and clear. This
can be due to factors such as the dis-
tance from the radio station, closeness of
other strong radio stations or the pres-
ence of buildings, bridges or other large
obstructions in the area.AM broadcasts can be received at
greater distances than FM broadcasts.
This is because AM radio waves are
transmitted at low frequencies. These
long, low frequency radio waves can fol-
low the curvature of the earth rather than
travelling straight out into the atmos-
phere. In addition, they curve around
obstructions so that they can provide bet-
ter signal coverage.FM broadcasts are transmitted at high
frequencies and do not bend to follow the
earth's surface. Because of this, FM
broadcasts generally begin to fade at
short distances from the station. Also,
FM signals are easily affected by build-
ings, mountains, or other obstructions.
These can result in certain listening con-
ditions which might lead you to believe a
problem exists with your radio. The fol-
lowing conditions are normal and do not
indicate radio trouble:AUDIO SYSTEM

should be started without depressing
the accelerator.✽ ✽
NOTICEDo not engage the starter for more than
10 seconds. If the engine stalls or fails to
start, wait 5 to 10 seconds before re-
engaging the starter. Excessive or
improper use of the starter may damage
it. The starter will not operate if:
Manual Transaxle- the clutch pedal is
not fully depressed.
Automatic Transaxle- the shift lever
is NOT in the P (Park) or N (Neutral)
position.
WARNING
- Ignition key
• Never turn the ignition switch to
LOCK or ACC while the vehicle is
moving. This would result in loss
of directional control and braking
function, which could cause an
accident or collision.
Before leaving the driver’s seat,
always make sure the shift lever
is engaged in 1
stgear for manual
transaxle or P (Park) for automat-
ic transaxle. Then, set the parking
brake fully and shut the engine
off. Unexpected and sudden vehi-
cle movement may occur if these
precautions are not taken.
Never reach for the ignition
switch, or any other controls
through the steering wheel while
the vehicle is in motion. The pres-
ence of your hand or arm in this
area could cause a loss of vehicle
control, an accident and serious
bodily injury or death.
Do not place any movable objects
around the driver’s seat as they
may move while driving, interfere
with the driver and lead to an
accident.
CAUTION -
Stall
If the engine stalls while you are in
motion, do not attempt to move the
shift lever to the P (Park) position. If
traffic and road conditions permit,
you may put the shift lever in the N
(Neutral) position while the vehicle
is still moving and turn the ignition
switch to the START position in an
attempt to restart the engine.
WARNING
Always wear appropriate shoes
when operating your vehicle.
Unsuitable shoes (high heels, ski
boots,etc.) may interfere with your
ability to use the brake and acceler-
ator pedal, and the clutch (if
equipped).

Driving your vehicle4 4
Manual transaxle operationThe manual transaxle has five forward
gears.
Press the clutch pedal down fully while
shifting, then release it slowly.
The gearshift lever must be returned to
the neutral position before shifting into R
(Reverse). The ring located immediately
below the shift knob must be pulled
upward while moving the shift lever to the
R position.Make sure the vehicle is completely
stopped before shifting into R (Reverse).
Never operate the engine with the
tachometer (rpm) in the red zone.✽ ✽
NOTICEWhen downshifting from fifth gear to
fourth gear, caution should be taken not
to inadvertently press the gear shift
lever sideways in such a manner that
second gear is engaged. Such a drastic
downshift may cause the engine speed to
increase to the point that the tachometer
will enter the red-zone. Such over-
revving of the engine may possibly cause
engine damage.
MANUAL TRANSAXLE (IF EQUIPPED)
OMG045003N
The ring (1) must be pulled up while moving the shift lever. The shift lever can be moved without pulling the ring (1).

Driving your vehicle
To shift into reverse, rest the lever in
neutral for at least 3 seconds after your
car is completely stopped. Then move
the lever into the reverse position.
During cold weather, shifting may be
difficult until the transaxle lubricant has
warmed up. This is normal and not
harmful to the transaxle.
If you've come to a complete stop and
it's hard to shift into 1st or R (Reverse),
put the shift lever in N (Neutral) posi-
tion and release the clutch. Press the
clutch pedal back down, and then shift
into 1st or R (Reverse) gear position.
✽ ✽
NOTICETo avoid premature clutch wear and
damage, do not drive with your foot
resting on the clutch pedal. Also, don’t
use the clutch to hold the vehicle
stopped on an uphill grade, while wait-
ing for a traffic light, etc.
DownshiftingWhen you must slow down in heavy traf-
fic or while driving up steep hills, down-
shift before the engine starts to labor.
Downshifting reduces the chance of
stalling and gives better acceleration
when you again need to increase your
speed. When the vehicle is traveling
down steep hills, downshifting helps
maintain safe speed and prolongs brake
life.
