Ignition Switch
▼Push Button Start Positions
The system operates only when the key
is within operational range.
Each time the push button start is
pressed, the ignition switches in the
order of
off, ACC, and ON. Pressing
the push button start again from ON
switches the ignition off.
1. Indicator light
2. Push button start
NOTE
The engine starts by pressing the
push button start while depressing
the clutch pedal (manual
transmission) or the brake pedal
(automatic transmission). To switch
the ignition position, press the push
button start without depressing the
pedal.
Do not leave the ignition switched
ON while the engine is not running.
Doing so could result in the battery
going dead. If the ignition is left in
ACC (For automatic transmission,
the selector lever is in the P position,
and the ignition is in ACC), the
ignition switches o ff automatically
after about 25 minutes.
O ff
The power supply to electrical devices
turns off and the indicator light
(amber) also turns off .
WARNING
Before leaving the driver's seat,
always switch the ignition o ff, set the
parking brake, and make sure the
selector lever is in P (automatic
transmission) position or in 1st gear
or R (manual transmission):
Leaving the driver's seat without
switching the ignition off, setting the
parking brake, and shifting the selector
lever to P (automat ic transmission)
position or to 1st gear or R (manual
transmission) is dangerous.
Unexpected vehicle movement could
occur which could result in an
accident.
In addition, if your intention is to leave
the vehicle for even a short period, it is
important to switch the ignition off, as
leaving it in another position will
disable some of the vehicle's security
systems and run the battery down.
ACC (Accessory)
Some electrical accessories will
operate and the indicator light (amber)
illuminates.
NOTE
The keyless entry system does not
function while the push button start
has been pressed to ACC, and the
doors will not lock/unlock even if they
have been locked manually.

Windshield Wipers andWasher
▼Windshield Wipers and Washer
The ignition must be switched ON to
use the wipers.
WARNING
Use only windshield washer
fluid or
plain water in the reservoir:
Using radiator antifreeze as washer
fl uid is dangerous. If sprayed on the
windshield, it will dirty the windshield,
a ff ect your visibility, and could result in
an accident.
Only use windshield washer fluid
mixed with anti-freeze protection in
freezing weather conditions:
Using windshield washer fluid without
anti-freeze protection in freezing
weather conditions is dangerous as it
could freeze on the windshield and
block your vision which could cause an
accident. In addition, make sure the
windshield is su fficiently warmed using
the defroster before spraying the
washer fluid.
CAUTION
 When the wipers are not used during
freezing temperatures or for a long
time, the wiper rubber may adhere
to the glass. If the wipers are
operated while adhered to the glass,
it could damage the wiper rubber
and motor.
 If the wipers are operated while the
glass is dry, the glass could be
scratched and the wiper rubber
damaged. When the glass is dry,
spray washer
fluid before operating
the wipers.
 If the amount of washer fluid spray is
insu fficient, do not use the washer
switch. If the washer switch
continues to be operated with no
washer fluid being sprayed, it could
lead to pump damage.
NOTE
If the windshield wipers are operated
under cold weather conditions or
during snowfall, they could stop due to
accumulated snow on the windshield.
If the windshield wipers stop due to
accumulated snow on the windshield,
park the vehicle in a safe place, turn
the wiper switch o ff, and then remove
the accumulated snow. If the wiper
switch is turned to another position

Authorized Mazda Dealer as soon as
possible.
WARNING
Do not drive with worn disc pads:
Driving with worn disc pads is
dangerous. The brakes could fail and
cause a serious accident. As soon as
you hear a screeching noise consult an
Authorized Mazda Dealer.
NOTE
In high humidity weather conditions,
brake noises, such as brake squeak or
brake squeal can be heard. It does not
indicate a malfunction.
▼Brake Assist
During emergency braking situations
when it is necessary to depress the
brake pedal with greater force, the
brake assist system provides braking
assistance, thus
enhancing braking
performance.

When the brake pedal is depressed
hard or depressed more quickly, the
brakes apply more firmly.
NOTE
When the brake pedal is depressed
hard or depressed more quickly, the
pedal will feel softer but the brakes
will apply more firmly. This is a
normal eff ect of the brake assist
operation and does not indicate a
malfunction.
When the brake pedal is depressed
hard or depressed more quickly, a
motor/pump operation noise may
be heard. This is a normal e ffect of
the brake assist and does not
indicate a malfunction.
The brake assist equipment does not

Antilock Brake System(ABS)
▼Antilock Brake System (ABS)
The ABS control unit continuously
monitors the speed of each wheel. If
one wheel is about to lock up, the ABS
responds by automatically releasing
and reapplying that wheel's brake.

The driver will feel a slight vibration in
the brake pedal and may hear a
chattering noise from the brake system.
This is normal ABS system operation.
Continue to depress the brake pedal
without pumping the brakes.

The warning light turns on when the
system has a malfunction.
Refer to ABS Warning Indication/
Warning Light on page 7-30.
WARNING
Do not rely on ABS as a substitute for
safe driving:
The ABS cannot compensate for unsafe
and reckless driving , excessive speed,
tailgating (following another vehicle
too closely), driving on ice and snow,
and hydroplaning (reduced tire friction
and road contact because of water on
the road surface). You can still have an
accident.
NOTE
Braking distances may be longer on
loose surfaces (snow or gravel, for
example) which usually have a hard
foundation. A vehicle with a normal
braking system may require less
distance to stop under these
conditions because the tires will
build up a wedge of surface layer
when the wheels skid.
The sound of the ABS operating may
be heard when starting the engine or
immediately after starting the
vehicle, however, it does not indicate
a malfunction.
