overheating MAZDA MODEL CX-9 2021 Owners Manual

Floor Mat
We recommend the use of Genuine
Mazda floor mats.
WARNING
Make sure the floor mats are hooked on the
retention pins to prevent them from
bunching up under the foot pedals:
Using a floor mat that is not secured is
dangerous as it will interfere with the
accelerator and brake pedal operation,
which could result in an accident.
Do not install two floor mats, one on top of
the other, on the driver's side:
Installing two floor mats, one on top of the
other, on the driver's side is dangerous as
the retention pins can only keep one floor
mat from sliding forward.
Loose floor mat(s) will interfere with the
foot pedals and could result in an accident.
If using an all-weather mat for winter use
always remove the original floor mat.
When setting a floor mat, position the
floor mat so that its grommets are inserted
over the pointed end of the retention posts.
Rocking the Vehicle
WA R N I N G
Do not spin the wheels at more than 56
km/h (35 mph), and do not allow anyone
to stand behind a wheel when pushing the
vehicle:
When the vehicle is stuck, spinning the
wheels at high speed is dangerous. The
spinning tire could overheat and explode.
This could cause serious injuries.
CAUTION
Too much rocking may cause engine
overheating, transaxle failure, and tire
damage.
If you must rock the vehicle to free it from
snow, sand or mud, depress the accelerator
slightly and slowly move the selector lever
from D to R position.
Before Driving
Driving Tips
3-51
CX-9_8JK1-EA-20G_Edition6_old 2021-12-8 9:30:44

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.

WARNING
Always use lower gears to reduce speed:
Holding the brake pedal down too long or too frequently is dangerous as it could cause the
brakes to overheat and lose power, resulting in loss of control and a serious accident. Use
lower gears to help reduce speed . Pull off the road and allow brakes to cool down whenever
braking performance feels reduced.
Overheated engine
The extra weight of the trailer may strain the engine on hot days and on long or steep
upgrades.
If the temperature gauge indicates overheating, turn off the air conditioner, drive safely to
the side of the road, park off the right-of- way and wait for engine to cool. Refer to
Overheating on page 7-23.
Parking
Always make sure the tires of the trailer and the tow vehicle are blocked while parked.
Apply the parking brake firmly and put the transaxle in P.
Avoid parking on an incline, but if you must, follow these instructions:
1. Depress and hold down the brake pedal.
2. Have a helper put wheel blocks against the downhill side of all vehicle and trailer tires.
3. Then release the brake pedal slowly until the blocks bear the load.
If the grade is downhill, turn the steering wheel so that the front of the front tires face
the curb.
If it is uphill, face the rear of the front tires against the curb.
4. Firmly apply the parking brake.
5. Shift the transaxle into P, and stop the engine.
To restart after parking on an incline:
1. With the transaxle in P, start the engine. (Be sure to depress and hold the brake pedal.)
2. Shift into gear.
3. Release the parking brake (also the foot brake) and pull away from the wheel blocks. Stop; apply the parking brake and shift into P.
4. Have a helper retrieve the wheel blocks.
Fuel consumption
Trailer towing causes higher fuel consumption.

Driving Tips
WARNING
Do not let the vehicle move in a direction
opposite to the direction selected by the
selector lever:
Do not let the vehicle move backward with
the selector lever in a forward position, or
do not let the vehicle move forward with
the selector lever in the reverse position.
Otherwise, the engine may stop, causing
the loss of the power brake and power
steering functions, and make it difficult to
control the vehicle which could result in an
accident.
Passing
For extra power when passing another
vehicle or climbing steep grades, depress
the accelerator fully. The transaxle will
shift to a lower gear, depending on vehicle
speed.
NOTE
The accelerator pedal may initially feel
heavy as it is being depressed, then feel
lighter as it is depressed further. This
change in pedal force aids the engine
control system in determining how much
the accelerator pedal has been
depressed for performing kickdown, and
functions to control whether or not
kickdown should be performed.
While the selector lever is in the M
position and the TCS is turned off,
manual shift mode does not switch to
automatic shift mode even if the
accelerator pedal is completely
depressed. Operate the selector lever.
Climbing steep grades from a stop
To climb a steep grade from a stopped
position:
1. Depress the brake pedal.
2. Shift to D or M1, depending on the load weight and grade steepness.
3. Release the brake pedal while gradually accelerating.
Descending steep grades
When descending a steep grade, shift to
lower gears, depending on load weight and
grade steepness. Descend slowly, using the
brakes only occasionally to prevent them
from overheating.
