( With Electric Parking Brake (EPB))
If the electric parking brake (EPB) cannot
be released when towing the vehicle,
transport the vehicle with all front and
rear wheels raised
off the ground as
shown in the figure. If the vehicle is
towed without raising the wheels off the
ground, the brake system could be
damaged.
Wheel dollies
Tiedown Hooks*
CAUTION
Do not use the front and rear tiedown
eyelets for towing the vehicle.
They have been designed only for securing
the vehicle to a transport vessel during
shipping.
Using the eyelets for any other purpose
could result in the vehicle being damaged.
▼ Tiedown Hooks
1. Remove the tiedown eyelet and the lug
wrench from the luggage compartment
(page 7-3).
2. Wrap a flathead screwdriver or similar
tool with a soft c loth to prevent
damage to a painted bumper, and open
the cap located on the front or rear
bumper.

SignalWarning
Brake System Warning
Light With Electric Parking Brake (EPB)
This warning has the following functions:
Parking brake warning/Warning light inspection
The light illuminates when the electric parking brake (EPB) is
applied with the igni-
tion switched to START or ON. It turns off when the electric pa rking brake (EPB) is
released.
When the light turns on
If the brake system warning light remains turned on even though the electric parking
brake (EPB) is released, the brak e fluid may be low or there could be a problem with
the brake system. Park the vehicle in a safe place immediately and contact an Author-
ized Mazda Dealer.
When the light is flashing
The light flashes if the electric parking brake (EPB) has a mal function.
If the light remains flashing ev en if the electric parking brake (EPB) switch is operat-
ed, consult an Authorized Mazd a Dealer as soon as possible.
WARNING
Do not drive with the brake system warning light illuminated. Contact an Authorized
Mazda Dealer to have the brakes inspected as soon as possible:
Driving with the brake system warning light illuminated is dangerous. It indicates that
your brakes may not work at all or that they could completely fail at any time. If this
light remains illuminated, after checking that the parking brake is fully released, have
the brakes inspected immediately.
CAUTION
In addition, the effectiveness of the braking may diminish so you may need to depress
the brake pedal more strongly than normal to stop the vehicle.
Electronic Brake Force Distribution System Wa r n i n g If the electronic brake force di
stribution control unit determines that some compo-
nents are operating incorrectly , the control unit may illuminate the brake system
warning light and the ABS warni ng light simultaneously. The problem is likely to be
the electronic brake force distribution system.
WARNING
Do not drive with both the ABS warning light and brake warning light illuminated.
Have the vehicle towed to an Authorized Mazda Dealer to have the brakes inspected as
soon as possible:
Driving when the brake system warning ligh t and ABS warning light are illuminated si‐
multaneously is dangerous.
When both lights are illuminated, the rear wheels could lock more quickly in an emer‐
gency stop than under normal circumstances.

SignalWarning
Power Steering Mal-
function Indicator Light The light illuminates/flashes if the electric power steering ha
s a malfunction.
If the light illuminates/flashes, stop the vehicle in a safe pl ace and do not operate the
steering wheel. There is no problem if the light turns off afte r a while. Contact an Au-
thorized Mazda Dealer if the lig ht illuminates/flashes continuously.
NOTE
If the indicator light illuminates/flashes, the power steering will not operate normal-
ly. In this happens, the st eering wheel can still be oper ated, however, the operation
may feel heavy compar ed to normal, or the steering wheel could vibrate when turn-
ing.
Repeatedly jerking the steering wheel left and right while the vehicle is stopped or
moving extremely slowly will cause the power steering system to go into protective
mode which will make the steering feel heavy, but this does not indicate a problem. If
this occurs, park the vehicle safely and wait several minutes for the system to return
to normal.
▼ Contact Authorized Mazda Deal
er and Have Vehicle Inspected
If any of the following warning lights o r the indicator light turns on/flashes, the system may
have a malfunction. Contact an Authorized Mazda Dealer to have your vehicle inspected.
SignalWarning
ABS Warning LightIf the ABS warning light stays on while you're driving, the ABS
control unit has detected
a system malfunction. If this occurs, your brakes will function normally as if the vehicle
had no ABS.
Should this happen, consult an A uthorized Mazda Dealer as soon as possible.
NOTE
When the engine is jump-started to charge the battery, uneven rpm occurs and the ABS
warning light may illuminate. If this occurs, it is the result of the weak battery and does
not indicate an ABS malfunction.
The brake assist system does not operate while the ABS warning light is illuminated.

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 cour
se.
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 condi tions of their use, however,
and may depart significantly from the norm because of variation s in driving habits, service
practices and differences in ro ad 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 contro lled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction
performance.
WA R N I N G
The traction grade assigned to this tire is based on braking (straight ahead) traction tests and
does not include acceleration cornering (t urning), hydroplaning, or peak traction
characteristics.
▼ Temperature-A, B, C
The temperature grades A (the hi
ghest), B, and C, represent the tire's resistance to the
generation of heat and its ability to dissipate heat when teste d 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 passeng er vehicle tires must meet
under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher
levels of performance on the labo ratory test wheel than the minimum required by law.

Traction: The traction grades, from highe st to lowest are AA, A, B, and C. The grades
represent the tire's ability to stop on wet pavement as measure d 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 : The temperature grades are A (the highest), B and C, represent ing the tire's
resistance to the generation of heat and its ability to dissipa te heat when tested under
controlled conditions on a spec ified indoor laboratory test whe el.
Snow Tires
In some heavy snow areas, local governments may require true sn ow tires, those with very
deeply cut tread. These tires should only be used in pairs or p laced on all four wheels. Make
sure you purchase snow tires that are the same size and construction type as the other tires
on your vehicle.
SAFETY WARNING
The following safety warning a ppears on the tire's sidewall.
SERIOUS INJURY MAY RESULT FROM:
EXPLOSION OF TIRE/RIM ASSEMBLY DUE TO IMPROPER MOUNTING-MATCH
TIRE DIAMETER TO RIM D IAMETER; NEVER EXCEED 40 psi (275 kPa) TO SEAT
BEADS-ONLY SPECIALLY TRAINED PERSONS SHOULD MOUNT TIRES.
