4 –97 When Driving
i-ACTIVSENSENOTE 
In the following cases, the Forward Sensing Camera (FSC) cannot detect target objects
correctly, and each system may be unable to operate normally. 
The height of the vehicle ahead is low. 
You drive your vehicle at the same speed as the vehicle ahead. 
Headlights are not turned on during the night or when going through a tunnel. 
In the following cases, the Forward Sensing Camera (FSC) may not be able to detect
target objects correctly. 
When driving next to walls with no patterning (including fences and longitudinally
striped walls). 
The taillights of the vehicle ahead are turned off. 
A vehicle is outside the illumination range of the headlights. 
The vehicle is making a sharp turn, or ascending or descending a steep slope. 
Entering or exiting a tunnel. 
Heavy luggage is loaded causing the vehicle to tilt. 
Strong light is shone at the front of the vehicle (back light or high-beam light from on-
coming vehicles). 
There are many light emitters on the vehicle ahead. 
When the vehicle ahead is not equipped with taillights or the taillights are turned off at
nighttime. 
The vehicle ahead has a special shape. For example, a vehicle towing a trailer house
or a boat, or a vehicle carrier carrying a vehicle with its front pointed rearward.

6 –42 Maintenance and Care
Owner Maintenance 
Underinflation can cause reduced fuel
economy, uneven and accelerated tire
wear, and poor sealing of the tire bead,
which will deform the wheel and cause
separation of tire from rim. 
Overinflation can produce a harsh ride,
uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
Keep your tire pressure at the correct
levels. If one frequently needs inflating,
have it inspected.
Tire Rotation
WARNINGRotate tires periodically:
Irregular tire wear is dangerous. To
equalize tread wear for maintaining
good performance in handling and
braking, rotate the tires every 12,000
km (7,500 miles). However Mazda
recommends to rotate every 8,000 km
(5,000 miles) to help increase tire life
and distribute wear more evenly.
Refer to Scheduled Maintenance on
page 6-4 .
During rotation, inspect them for correct
balance.
Do not include (TEMPORAR Y USE ONLY)
spare tire in rotation. Forward Also, inspect them 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 .
CAUTION Rotate unidirectional tires and radial
tires that have an asymmetrical tread
pattern or studs only from front to rear,
not from side to side. Tire performance
will be reduced if rotated from side to
side.
(With limited-slip differential)
Do not use the following: 
Tires not of the designated size 
Tires of different sizes or types at
the same time 
Tires not sufficiently inflated
If these instructions are not followed,
the rotation of the left and right wheels
will be different and will thus apply
a constant load on the limited-slip
differential.
This will cause a malfunction.
