compression ratio MAZDA MODEL CX-9 2020 Owners Manual (in English)

Avoid jerky starts or sudden acceleration.
Avoid sudden braking. It may cause loss of control and result in jackknifing, especially so
on wet or slippery roads.
Shift the selector lever to the D position wh en towing a trailer in hilly terrain or when
heavily loaded.
The D position will allow operating th e vehicle without frequent shifting.
Lane changes and turning
Avoid quick lane changes, sudden turns, and tight turns. Slow down before turning to avoid
the need of sudden braking.
A turning trailer will make a tighter arc than th e tow vehicle. Compensate with turns that are
larger than normal.
Passing
Plan well ahead to pass other vehicles, and provide plenty of room before changing lanes.
Crosswinds from passing vehicles, especially larger ones, and the effects of rough roads will
affect handling.
If swaying occurs, firmly grip the steering wheel and reduce speed immediately, but
gradually.
Steer straight ahead. If no extreme correc tion of steering or braking is made, the
combination of less speed and firm steering will result in stability.
Backing up
Backing a vehicle with a trailer requires practice and patience. Back slowly, and have a
helper outside at the rear of the trailer to reduce the risk of an accident.
To turn the trailer, place your hand at the bott om of the steering wheel and turn it in the
direction you want the trailer to go. Make only slight movements to prevent sharp or
prolonged turning.
Ascending a hill
Shift into a lower gear to redu ce the possibility of overloading or overheating the engine, or
both.
Descending a hill
Shift into a lower gear and use engine compression as a braking effect.

Strong signal noise
This occurs very close to a transmitter
tower. The broadcast signals are extremely
strong, so the result is noise and sound
breakup at the radio receiver.
Station drift noise
When a vehicle reaches the area of 2
strong stations broadcasting at similar
frequencies, the original station may be
temporarily lost and the second station
picked up. At this time there will be some
noise from this disturbance.
Station 2
88.3 MHz
Station 1
88.1 MHz

Operating Tips for MP3
MP3 stands for MPEG Audio Layer 3,
which is standardized voice compression
established by the ISO
*1 working group
(MPEG).
Use of MP3 allows for audio data to be
compressed to approximately a tenth of
the source data size.
This unit plays files with the extension
(.mp3) as MP3 files.
*1 International Organization for
Standardization
CAUTION
Do not use an audio file extension on files
other than audio files. In addition, do not
change the audio file extension. Otherwise,
the unit will not recognize the file correctly
resulting in noise or a malfunction.
