• Do not expose tapes to direct sunlight, high humidity, extreme heat or

extreme cold. Allow tapes that may have been exposed to extreme
temperatures to reach a moderate temperature before playing.

• Tighten very loose tapes by inserting a finger or pencil into the hole

and turning the hub.

• Remove loose labels before inserting tapes.
• Do not leave tapes in the cassette player for a long time when not

being played.

Radio frequency information

The Federal Communications Commission (FCC) and the Canadian Radio
and Telecommunications Commission (CRTC) establish the frequencies
AM and FM stations may use for their broadcasts. Allowable frequencies
are:
• AM 530, 540–1600, 1610 kHz

a

• FM 87.9

b

, 88.1–107.7, 107.9 MHz

Not all frequencies are used in a given area.

a

Some radios may tune up to 1710 kHz.

b

Some radios may tune down to 87.7 MHz.

Radio reception factors

Three factors can affect radio reception:
• Distance/strength. The further an FM signal travels, the weaker it is.

The listenable range of the average FM station is approximately 40 km
(24 miles). This range can be affected by “signal modulation.” Signal
modulation is a process radio stations use to increase their
strength/volume relative to other stations.

• Terrain. Hills, mountains and tall buildings between your vehicle’s

antenna and the radio station signal can cause FM reception problems.
Static can be caused on AM stations by power lines, electric fences,
traffic lights and thunderstorms. Moving away from an interfering
structure (out of its “shadow”) returns your reception to normal.

• Station overload. Weak signals are sometimes captured by stronger

signals when you pass a broadcast tower. A stronger signal may
temporarily overtake a weaker signal and play while the weak station
frequency is displayed.

Controls and features

The audio system automatically switches to single channel reception if it
will improve the reception of a station normally received in stereo.

SPEED CONTROL (IF EQUIPPED)

To turn speed control on
• Press ON.
Vehicle speed cannot be controlled
until the vehicle is traveling at or
above 48 km/h (30 mph).

Do not use the speed control in heavy traffic or on roads that
are winding, slippery, or unpaved.

Do not shift the gearshift lever into N (Neutral) with the speed
control on.

To turn speed control off
• Press OFF or
• Turn off the vehicle ignition.

Once speed control is switched off, the previously programmed set speed
will be erased.

To set a speed
• Press SET/SET ACC/SET ACCEL.

For speed control to operate, the
speed control must be ON and
the vehicle speed must be greater
than 48 km/h (30 mph).

If you drive up or down a steep hill, your vehicle speed may vary
momentarily slower or faster than the set speed. This is normal.

Speed control cannot reduce the vehicle speed if it increases above the
set speed on a downhill. If your vehicle speed is faster than the set
speed while driving on a downhill, you may want to shift to the next
lower gear or apply the brakes to reduce your vehicle speed.

If your vehicle slows down more than 16 km/h (10 mph) below your set
speed on an uphill, your speed control will disengage. This is normal.
Pressing RES/RSM/RESUME will re-engage it.

Do not use the speed control in heavy traffic or on roads that
are winding, slippery, or unpaved.

To set a higher set speed
• Press and hold SET/SET ACC/

SET ACCEL. Release the control
when the desired vehicle speed is
reached or

• Press and release SET/SET ACC/

SET ACCEL. Each press will
increase the set speed by
1.6 km/h (1 mph) or

• Accelerate with your accelerator

pedal. When the desired vehicle
speed is reached, press and release SET/SET ACC/SET ACCEL.
