
The warning indication/warning light illuminates if there is a problem with the system.
Have your vehicle inspected at an Authorized Mazda Dealer. 
The LDWS does not operate when the warning indication/warning light illuminates.
CAUTION 
A problem in the system may be indicated under the following conditions. Have your
vehicle inspected at an Authorized Mazda Dealer.

When the warning indication/warning light illuminates while driving the vehicle.
When the system is canceled automatically, the warning indication/warning
light illuminates. Normally, the system restores automatically and the warning
indication/warning light turns off, however, if the warning indication/warning light
illuminates, there may be a problem with the system.

The warning indication/warning light does not illuminate when the ignition is
switched ON.

Always use tires for all wheels that are of the specified size, and the same
manufacture, brand, and tread pattern. In addition, do not use tires with significantly
different wear patterns on the same vehicle. If such improper tires are used, the LDWS
may not operate normally.

When an emergency spare tire is used, the system may not operate normally.
NOTE If the windshield area in front of the Forward Sensing Camera (FSC) is fogged or
obstructed, the light turns on temporarily. If the light remains turned on, there may be a
problem with the system.

Tire Information (U.S.A.)
WARNING Always check the tire inflation pressures on a regular basis according to the
recommended tire inflation pressure on the tire label and in conjunction with the
information in this owner's manual:
Driving your vehicle with under-inflated tires is dangerous.
Under-inflation is the most common cause of failures in any kind of tire and may result
in severe cracking, tread separation or “blowout”, with unexpected loss of vehicle
control and increased risk of injury. Under-inflation increases sidewall flexing and
rolling resistance, resulting in heat buildup and internal damage to the tire. It results in
unnecessary tire stress, irregular wear, loss of control and accidents. A tire can lose up to
half of its air pressure and not appear to be flat!
It is impossible to determine whether or not tires are properly inflated just by looking at
them.
Checking Tire Pressure1. When you check the air pressure, make sure the tires are cold — meaning they are not hot
from driving even a mile.
2. Remove the cap from the valve on one tire.
3. Firmly press a tire gauge onto the valve.
4. Add air to achieve recommended air pressure.
5. If you overfill the tire, release air by pushing on the metal st em in the center of the valve.
Then recheck the pressure with your tire gauge.
6. Replace the valve cap.
7. Repeat with each tire, including the spare.
NOTE
Some spare tires require higher inflation pressure.
8. Visually inspect the tires to make sure there are no nails or other objects embedded that
could poke a hole in the tire and cause an air leak.
9. Check the sidewalls to make sure there are no gouges, cuts, bulges, cracks or other
irregularities.

Tire Information (U.S.A.)
Tire MaintenanceImproper or inadequate vehicle maintenance can cause tires to w ear abnormally. Here are
some important maintenance points:
Tire Inflation PressureInspect all tire pressure monthly (including the spare) when the tires are cold. Maintain
recommended pressures for the best ride, top handling, and minimum tire wear. Use the
pressures specified on the vehicle tire information placard or t ire label for optimum service.
Tire RotationTo equalize tread wear, rotate the tires every 12,000 km (7,500 miles) at the latest or sooner
if irregular wear develops. Mazda recommends to rotate every 8,000 km (5,000 miles) to
help increase tire life and distribute wear more evenly.
Do not include (TEMPORAR Y USE ONLY)
spare tire in rotation. Forward
Inspect the tires for uneven wear and damage. Abnormal wear is usually caused by one or a
combination of the following: 
Incorrect tire pressure 
Improper wheel alignment 
Out-of-balance wheel 
Severe braking
After rotation, inflate all tire pressures to specification (page 9-8 ) and inspect the lug
nuts for tightness.
(With tire pressure monitoring system)
After adjusting the tire pressure, initialization of the tire pressure monitoring system is
necessary to make the system operate normally.
Refer to Tire Pressure Monitoring System Initialization on page 4-108 .

Tire Information (U.S.A.)NOTE
Tires degrade over time, even when they are not being used on the road. It is recommended
that tires generally be replaced when they are 6 years or older. Heat caused by hot climates
or frequent high loading conditions can accelerate the aging process. The period in which
the tire was manufactured (both week and year) is indicated by a 4-digit number.
Refer to Tire Labeling on page 8-24 .
Safety PracticesThe way you drive has a great deal to do with your tire mileage and safety. So cultivate good
driving habits for your own benefit. 
Observe posted speed limits and drive at speeds that are safe for the existing weather
conditions 
Avoid fast starts, stops and turns 
Avoid potholes and objects on the road 
Do not run over curbs or hit the tire against the curb when parking
CAUTION If you feel a sudden vibration or ride disturbance while driving or you suspect your tire
or vehicle has been damaged, immediately reduce your speed. Drive with caution until
you can safely pull off the road. Stop and inspect the tire for damage. If the tire is under-
inflated or damaged, deflate it, remove the tire and rim and replace it with your spare tire.
If you cannot detect a cause, have the vehicle towed to the nearest vehicle or tire dealer to
have the vehicle inspected.
