2019 MAZDA MODEL CX-9 compression ratio

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 when towing a trailer in hilly terrain or when
heavily loaded.
The D position will allow operating the vehicle without frequen t shifting.
Lane changes and turning
Avoid quick lane changes, sudden turns, and tight turns. Slow d own before turning to avoid
the need of sudden braking.
A turning trailer will make a tighter arc than the tow vehicle. Compensate with turns that are
larger than normal.
Passing
Plan well ahead to pass other v ehicles, and provide plenty of r oom before changing lanes.
Crosswinds from passing vehicles, especially larger ones, and t he effects of rough roads will
affect handling.
If swaying occurs, firmly grip the steering wheel and reduce sp eed immediately, but
gradually.
Steer straight ahead. If no extr eme correction of steering or b raking is made, the
combination of less speed and firm steering will result in stab ility.
Backing up
Backing a vehicle with a traile r requires practice and patience . Back slowly, and have a
helper outside at the rear of th e trailer to reduce the risk of an accident.
To turn the trailer, place your ha nd at the bottom of the steering wheel and turn it in the
direction you want the trailer to go. Make only slight movement s to prevent sharp or
prolonged turning.
Ascending a hill
Shift into a lower gear to redu ce the possibility of overloadin g or overheating the engine, or
both.
Descending a hill
Shift into a lower gear and use engine compression as a braking effect.
