NOTElUse of tire chains on a vehicle equipped
with P225/40R18 specification tires could
cause interference with the vehicle body
and scratching. If tire chains are to be used,
replace both front and rear tires with P
205/50R17 tires. Please consult an
Authorized Mazda Dealer.
lIf your vehicle is equipped with the tire
pressure monitoring system, the system may
not function correctly when using tire
chains.
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 chain
bands 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.

Driving Tips
4-11

Ignition Switch
With advanced key
Refer to“Starting the engine (page 3-12)”
for information on how to use the ignition
switch.
qIgnition Switch Positions
(Without Advanced Key)
OFF
The power supply to electrical devices is
turned off. Only in this position can the
key be removed.
WARNING
Do not stop the engine while the
vehicle is moving:
Stopping the engine while the vehicle
is moving for any reason other than
in an emergency is dangerous.
Stopping the engine while the vehicle
is moving will result in reduced
braking ability due to the loss of
power braking, which could cause an
accident and serious injury.
Before leaving the driver's seat, always
switch the ignition to OFF, set the
parking brake and make sure the shift
lever is in P (automatic transaxle) or in
1st gear or R (manual transaxle):
It is important to switch the ignition
to OFF even if you are not removing
the key from the ignition or leaving
the vehicle. Leaving the key in other
positions will disable some of the
vehicle security systems and run the
battery down.
Leaving the driver's seat without
switching the ignition to 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. This could
cause an accident.
ACC (Accessory)
In this position, some electrical
accessories will operate.
ON
This is the normal running position after
the engine is started. Some indicator
lights/warning lights should be inspected
before the engine is started (page 5-47).

Driving Your Mazda
Starting and Driving

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.
ØAlways 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.
