Before Driving Your Mazda
Driving Tips
Form No. 8S15-EA-03G
When driving on ice or in water, snow,
mud, sand, or similar hazard:
•Be cautious and allow extra distance
for braking.
• Avoid sudden braking and quick
steering.
• If your vehicle is not equipped with
ABS, brake with the pedal by using a
light up-down motion. Don
’t hold the
pedal down constantly.
If your vehicle is equipped with ABS,
don ’t pump the brakes. Continue to
press down on the brake pedal.
• If you get stuck, select a lower gear and
accelerate slowly. Don
’t spin the rear
wheels.
• For more traction in starting on
slippery surfaces such as ice or packed
snow, use sand, rock salt, chains,
carpeting, or other nonslip material
under the rear wheels. If you must rock the vehicle to free it from
snow, sand, or mud, depress the
accelerator slightly and slowly move the
shift lever from 1 (D) to R.
Hazardous Driving
Downshifting on Slippery Surfaces:
Downshifting into lower gear while
driving on slippery surfaces is
dangerous. The sudden change in tire
speed could cause the tires to skid.
This could lead to loss of vehicle
control and an accident. If it is
necessary to downshift on slippery
surfaces, be very careful.
NOTE
Use snow chains only on the rear
wheels.
WARNING
Rocking the Vehicle
Spinning the Wheels:
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. Don't spin the wheels at
more than 56 km/h (35 mph), and
don't allow anyone to stand behind a
wheel when pushing the vehicle.
Too much rocking may cause engine
overheating, transmission failure, and
tire damage.

Uniform Tire Quality Grading System (UTQGS)
This information relates to the tire grading system developed by the U.S. National
Highway Traffic Safety Administration for grading tires by tread wear, traction, and
temperature performance.

Tr e a d We a r
The tread wear grade is a comparative rating based on the wear rate of the tire when tested
under controlled conditions on a specified government test course.
For example, a tire graded 150 would wear one-and-a-half times as well on the government
course as a tire graded 100.
The relative performance of tires depends upon the actual conditions of their use, however,
and may depart significantly from the norm because of variations in driving habits, service
practices and differences in road characteristics and climate.

Traction-AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B, and C. These grades represent
the tire
’s ability to stop on wet pavement as measured under controlled conditions on
specified government test surfaces of asphalt and concrete. A tire marked C may have poor
traction performance.

Te m p e r a t u r e - A , B , C
The temperature grades are A (the highest), B, and C, represent the tire
’s resistance to the
generation of heat and its ability to dissipate heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire
life, and excessive temperatures can lead to sudden tire failure.
Grade C corresponds to a level of performance which all passenger vehicle tires must meet
under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent
higher levels of performance on the laboratory test wheel than the minimum required by
law.
Uniform Tire Quality Grading System (UTQGS)
The traction grade assigned to this tire is based on braking (straight ahead) traction
tests and does not include acceleration cornering (turning), hydroplaning, or peak
traction characteristics.
