2021 MAZDA MODEL CX-3 oil change

Do not operate a vehicle with a damaged seat belt:
Using a damaged seat belt is dangerous. An accident could damage the belt webbing of the
seat belt in use. A damaged seat belt cannot pr ovide adequate protection in a collision. Have
an Authorized Mazda Dealer inspect all seat be lt systems in use during an accident before
they are used again.
Have your seat belts changed immediately if the pretensioner or load limiter has been
expended:
Always have an Authorized Mazda Dealer imme diately inspect the seat belt pretensioners
and air bags after any collision. Like the air ba gs, the seat belt pretensioners and load limiters
will only function once and must be replaced aft er any collision that caused them to deploy. A
seat belt with an expended pret ensioner or load limiter is still better than wearing no seat belt
at all; however, if the seat belt pretensioners and load limiters are not replaced, the risk of
injury in a collision will increase.
Positioning the Shoulder Portion of the Seat Belt:
Improper positioning of the shoulder portion of the seat belt is dangerous. Always make sure
the shoulder portion of the seat belt is positioned across your shoulder and near your neck,
but never under your arm, on yo ur neck, or on your upper arm.
Positioning the Lap Portion of the Seat Belt:
The lap portion of the seat belt worn too high is dangerous. In a collision, this would
concentrate the impact force directly on the abdominal area, causing serious injury. Wear the
lap portion of the belt snugly and as low as possible.
CAUTION
Belt retraction may become difficult if the belts and rings are soiled, so try to keep them clean.
For more details about cleaning the seat belts, refer to "Seat Belt Maintenance" (page 6-59).

Ring
▼ Pregnant Women and Persons with Serious Medical Conditions
Pregnant women should always wear seat belts. Ask your doctor for specific
recommendations.
The lap belt should be worn SNUGLY AND AS LOW AS POSSIBLE OVER THE HIPS.

Do not use the front bumper to push other vehi cles or obstructions such as when pulling
out of a parking space. Otherwise, the radar sensor (front) could be hit and its position
deviated.
 Do not remove, disassemble, or modify the radar sensor (front).
 For repairs, replacement or paint work around the radar sensor (front), consult an
Authorized Mazda Dealer.
 Do not modify the suspension. If the suspensi on are modified, the vehicle's posture could
change and the radar sensor (front) may not be able to correctly detect a vehicle ahead or
an obstruction.
NOTE
Under the following conditions, the radar sensor (front) may not be able to detect vehicles
ahead or obstructions correctly and each system may not operate normally.
The rear surface of a vehicle ahead does not reflect radio waves effectively, such as an
unloaded trailer or an automobile with a loading platform covered by a soft top,
vehicles with a hard plastic tailgate, and round-shaped vehicles.
Vehicles ahead with low vehicle height and thus less area for reflecting radio waves.
Visibility is reduced due to a vehicle ahead ca sting off water, snow, or sand from its tires
and onto your windshield.
The luggage compartment is loaded with heavy objects or the rear passenger seats are
occupied.
Ice, snow, or soiling is on the front surface of the front emblem.
During inclement weather such as rain, snow, or sand storms.
When driving near facilities or objects emitting strong radio waves.
Under the following conditions, the radar sensor (front) may not be able to detect vehicles
ahead or obstructions.
The beginning and end of a curve.
Roads with continuous curves.
Narrow lane roads due to road construction or lane closures.
The vehicle ahead enters the radar sensor's blind spot.
The vehicle ahead is running abnormally due to accident or vehicle damage.
Roads with repeated up and down slopes
Driving on poor roads or unpaved roads.
The distance between your vehicle and the vehicle ahead is extremely short.
A vehicle suddenly comes close such as by cutting into the lane.
To prevent incorrect operation of the system, use tires of the same specified size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use tires
with significantly different wear patterns or tire pressures on the same vehicle (Including
the temporary spare tire).
If the battery power is weak, the system may not operate correctly.
