AUDIO
290Radio reception
Usually, a problem with radio reception does not mean there
is a problem with your radio
− it is just the normal result of
conditions outside the vehicle.
For example, nearby buildings and terrain can interfere with
FM reception. Power lines or telephone wires can interfere
with AM signals. And of course, radio signals have a limited
range. The farther you are from a station, the weaker its signal
will be. In addition, reception conditions change constantly as
your vehicle moves.
Here are some common reception problems that probably do
not indicate a problem with your radio:
FM
Fading and drifting stations − Generally, the ef fective range
of FM is about 40 km (25 miles). Once outside this range, you
may notice fading and drifting, which increase with the
distance from the radio transmitter. They are often
accompanied by distortion.
Multipath − FM signals are reflective, making it possible for
two signals to reach your antenna at the same time. If this
happens, the signals will cancel each other out, causing a
momentary flutter or loss of reception.
Static and fluttering − These occur when signals are blocked
by buildings, trees, or other large objects. Increasing the bass
level may reduce static and fluttering. Station swapping −
If the FM signal you are listening to is
interrupted or weakened, and there is another strong station
nearby on the FM band, your radio may tune in the second
station until the original signal can be picked up again.
AM
Fading − AM broadcasts are reflected by the upper
atmosphere − especially at night. These reflected signals can
interfere with those received directly from the radio station,
causing the radio station to sound alternately strong and weak.
Station interference − When a reflected signal and a signal
received directly from a radio station are very ne arly the same
frequency, they can interfere with each other, making it dif ficult
to hear the broadcast.
Static − AM is easily affected by external sources of electrical
noise, such as high tension power lines, lightening, or electrical
motors. This results in static.
Caring for your cassette player and tapes
For the best performance for your cassette player and tapes:
Clean the tape head and other parts regularly.
 A dirty tape head or tape path can decrease sound quality
and tangle your cassette tapes. The easiest way to clean
them is by using a cleaning tape. (A wet type is
recommended.)

BEFORE STARTING THE ENGINE
1. Check the area around the vehicle before entering it.
2. Adjust seat cushion length, seat position, seatback angle,
seat cushion angle, seat cushion height, head restraint height
and steering wheel angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts.

SMART IGNITION SWITCH WITH STEERING LOCK
31L345a
Carrying a smart key allows you to start the engine
without the key being inserted into the ignition switch.
The smart key system can be deactivated using a key cancel
switch. For details, see “Deactivating the smart key system”
on page 34.

STARTING AND DRIVING
299
31L346a
When you enter the vehicle carrying a sm art key and push
the ignition switch, the electronic code in the key is
automatically checked as to whether it corresponds to the
registered ID code for the vehicle. The key indicator light
comes on, the steering column lock is released, and the
engine immobilizer system is cancelled.
At this time, the security indicator light goes off and you can
start the engine when you turn the ignition switch and the key
indicator light does not come on. When you turn the ignition
switch, turn it slowly and surely. If you turn it quickly, it may
become stuck. To free it, see the following “If the ignition switch
seems to be stuck”.
If you push the ignition switch when the smart key is not within
the effective range of the smart key system, a warning tone
sounds and “Key is not Detected” appears on the display. If the ignition switch seems to be stuck:
To free the ignition switch, perform the following:
31L638
1. Push the ignition switch.
31L639
2. Be sure to push the ignition switch while turning the
steering wheel slightly in either direction, and then turn
the switch.

STARTING AND DRIVING
300“START” Starter motor on. The ignition switch will
return to the “ON” position when released.
For starting tips, see page 304.
“ON” Engine on and all accessories on.
This is the normal driving position.
NOTICE
Do not leave the ignition switch in the “ON” position if
the engine is not running. The battery will discharge
and the electronic ignition system could be damaged.
“ACC” Accessories such as the radio operate, but the
engine is off.
31L347
“LOCK” Engine is off and the steering wheel is locked.
When
you leave your vehicle, be sure to turn the ignition switch
to the “LOCK” position and carry the smart key.
 If you open the driver’s door without returning the ignition
switch to the “LOCK” position, beeps keep sounding while
the door is opened.
 If you close a door to leave your vehicle while carrying a key
on which the ignition switch has not been returned to the
“LOCK” position, “Key is not Detected” appears on the
multi−information display, a warning tone sounds inside and
beeps sound outside.
 If the selector lever is in a position other than “P”, you cannot
turn the ignition switch to the “LOCK” position. At this time,
when you open the driver’s door and are going to get out of
the vehicle, “Shift to P Range” appears on the
multi−information display and a warning tone sounds inside.

STARTING AND DRIVING
301
When you turn the ignition switch to the “LOCK” position, the
engine immobilizer system is automatically set. See “Engine
immobilizer system” on page 17.
If, in an emergency, you must turn the engine off while the
vehicle is moving, turn the ignition switch only to “ACC”.
