Hazardous Driving
WARNING
Be extremely careful if it is necessary to
downshift 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.
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.
When driving on ice or in water, snow,
mud, sand, or similar hazards:
lBe cautious and allow extra distance
for braking.
lAvoid sudden braking and sudden
maneuvering.
lDo not pump the brakes. Continue to
press down on the brake pedal.
Refer to Anti-Lock Brake System
(ABS) on page 5-8.
lIf you get stuck, select a lower gear and
accelerate slowly. Do not spin the front
wheels.
lFor 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 front wheels.
NOTE
Use snow chains only on the front wheels.
Floor Mat
WARNING
Make sure the floor mats are hooked
on the retention pins to prevent them
from bunching up under the foot
pedals: Using a floor mat that is not secured
is dangerous as it will interfere with
the accelerator and brake pedal
operation, which could result in an
accident.
Do not install two floor mats, one on
top of the other, on the driver's side: Installing two floor mats, one on top
of the other, on the driver's side is
dangerous as the retention pins can
only keep one floor mat from sliding
forward.
In using a heavy duty floor mat for
winter use always remove the
original floor mat.
Loose floor mat(s) will interfere with
the foot pedal and could result in an
accident.
When setting a floor mat, position the
floor mat so that its eyelets are inserted
over the pointed end of the retention
posts.

Install the chains on the front tires.
Do not use chains on the rear tires.
Please consult an Authorized Mazda
Dealer.
Installing the chains
1. Remove the wheel covers, or the chainbands will scratch them.
2. Secure the chains on the front tires as tightly as possible. Always follow the
chain manufacturer's instructions.
3. Retighten the chains after driving 1/2 ―1 km (1/4 ―1/2 mile).
Driving In Flooded Area
WARNING
Dry wet brakes by driving very slowly
and applying the brakes lightly until
brake performance returns to normal:
Driving with wet brakes is
dangerous. Increased stopping
distance or the vehicle pulling to one
side when braking could result in a
serious accident. Light braking will
indicate whether the brakes have
been affected.
CAUTION
Do not drive the vehicle on flooded
roads as it could cause short
circuiting of electrical/electronic
parts, or engine damage or stalling
from water absorption. If the vehicle
has been immersed in water, consult
an Authorized Mazda Dealer.

Ignition Switch
With advanced key
Refer to“Starting the engine (page 3-12) ”
for information on how to use the ignition
switch.
q Ignition Switch Positions
(Without Advanced Key)
The engraved mark on the actual vehicle
may read OFF or LOCK depending on the
type of ignition system.
OFF/LOCK
The power supply to electrical devices is
turned off. Only in this position can the
key be removed.
WARNING
Remove the key only when the vehicle
is parked (with steering lock
mechanism):
Removing the key from the ignition
switch while the vehicle is moving is
dangerous. Removing the key allows
the steering wheel to lock. You will
lose steering control and a serious
accident could occur.
Before leaving the driver's seat, always
switch the ignition off, set the parking
brake, and make sure the shift lever is
in P (automatic transaxle) or in 1st gear
or R (manual transaxle): Leaving the driver's seat without
switching the ignition off, setting the
parking brake, and shifting the shift
lever to P (automatic transaxle) or to
1st gear or R (manual transaxle) 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.
NOTE
If turning the key is difficult, move the steering
wheel left and right.
Leaving the key in any position but the OFF/
LOCK position also disables some of the
security features and may run the battery
down.
ACC (Accessory)
In this position, some electrical
accessories will operate.

CAUTION
ØDo not drive with your foot held
on the clutch pedal or brake pedal,
or hold the clutch pedal depressed
halfway unnecessarily. Doing so
could result in the following:
ØThe clutch and brake parts will
wear out more quickly.
ØThe brakes can overheat and
adversely affect brake
performance.
Ø Always depress the brake pedal
with the right foot. Applying the
brakes with the unaccustomed left
foot could slow your reaction time
to an emergency situation
resulting in insufficient braking
operation.
ØWear shoes appropriate for driving
in order to avoid your shoe
contacting the brake pedal when
depressing the accelerator pedal.
qParking Brake
WARNING
Before leaving the driver's seat, always
switch the ignition off, set the parking
brake, and make sure the shift lever is
in P (automatic transaxle) or in 1st gear
or R (manual transaxle):
Leaving the driver's seat without
switching the ignition off, setting the
parking brake, and shifting the shift
lever to P (automatic transaxle) or to
1st gear or R (manual transaxle) 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.
CAUTION
Driving with the parking brake on
will cause excessive wear of the brake
linings or pads.
NOTE
For parking in snow, refer to Winter Driving
(page 4-9) regarding parking brake use.
