WARNING
Remove the key only when the vehicle
is parked:
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 off the ignition, 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, jiggle the steering
wheel from side to side.
Leaving the key in any position but LOCK
position also disables some of the security
features and may run the battery down.
ACC (Accessory)
The steering wheel unlocks and some
electrical accessories will operate.
ON
This is the normal running position after
the engine is started. The warning lights
(except brakes) should be inspected
before the engine is started (page 5-39).
NOTE
When the ignition switch is turned to the ON
position, the sound of the fuel pump motor
operating near the fuel tank can be heard. This
does not indicate an abnormality.
NOTE
(With headlight auto-leveling)
When the ignition switch is turned to the ON
position, the sound of the headlight leveling
motors operating at the front of the engine
compartment can be heard. This does not
indicate an abnormality.
START
The engine is started in this position. It
will crank until you release the key; then
it returns to the ON position. The brake
warning light can be checked after the
engine is started (page 5-39).
qIgnition Key Reminder
If the ignition is switched to off (LOCK)
or ACC with the key inserted, a
continuous beep sound will be heard
when the driver's door is opened.
NOTE
A personalized function is available to change
the sound volume for the ignition key reminder.
Refer to Personalization Features on page
10-9.

Starting the Engine
With advanced key
Refer to“Starting the engine (page 3-11)”
for information on how to start the engine.
NOTE
Engine-starting is controlled by the spark
ignition system.
This system meets all Canadian Interference-
Causing Equipment Standard requirements
regulating the impulse electrical field strength
of radio noise.
1. Occupants should fasten their seat
belts.
2. Make sure the parking brake is on.
3. Depress the brake pedal.
4.(Manual transaxle)
Depress the clutch pedal all the way
and shift into neutral.
Keep the clutch pedal depressed while
cranking the engine.
(Automatic transaxle)
Put the vehicle in park (P). If you must
restart the engine while the vehicle is
moving, shift into neutral (N).
NOTE
(Manual transaxle)
The starter will not operate unless the clutch is
depressed sufficiently.
(Automatic transaxle)
The starter will not operate if the shift lever is
notin P or N.
5. Turn the ignition switch to the START
position and hold (up to 10 seconds at
a time) until the engine starts.
CAUTION
Do not try the starter for more than
10 seconds at a time. If the engine
stalls or fails to start, wait 10 seconds
before trying again. Otherwise, you
may damage the starter and drain
the battery.
6. After starting the engine, let it idle for
about 10 seconds.
NOTE
lIn extremely cold weather or after the
vehicle has not been driven in several days,
let the engine warm up without operating
the accelerator.
lWhether the engine is cold or warm, it
should be started without use of the
accelerator.
lIf the engine does not start the first time,
refer to Starting a Flooded Engine under

Brake System
qFoot Brake
Your Mazda has power-assisted brakes
that adjust automatically through normal
use.
Should power-assist fail, you can stop by
applying greater force than normal to the
brake pedal. But the distance required to
stop will be greater than usual.
WARNING
Do not coast with the engine stalled or
turned off, find a safe place to stop:
Coasting with the engine stalled or
turned off is dangerous. Braking will
require more effort, and the brake's
power-assist could be depleted if you
pump the brake. This will cause
longer stopping distances or even an
accident.
Shift to a lower gear when going down
steep hills:
Driving with your foot continuously
on the brake pedal or steadily
applying the brakes for long
distances is dangerous. This causes
overheated brakes, resulting in
longer stopping distances or even
total brake failure. This could cause
loss of vehicle control and a serious
accident. Avoid continuous
application of the brakes.
Dry brakes that have become wet by
driving very slowly and applying the
brakes lightly until brake performance
is 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.

qBrake System Warning Light
This warning has the following functions:
Parking brake warning
The light illuminates when the parking
brake is applied with the ignition switched
to START or ON. It turns off when the
parking brake is fully released.
Low brake fluid level warning
If the light stays on after the parking brake
is fully released, you may have a brake
problem.
Drive to the side of the road and park off
the right-of-way.
You may notice that the pedal is harder to
depress or that it may go closer to the
floor. In either case, it will take longer to
stop the vehicle.
1. With the engine stopped, open the
hood and check the brake fluid level
immediately, and then add fluid if
required (page 8-22).
2. After adding fluid, check the light
again.
If the warning light remains on, or if the
brakes do not operate properly, do not
drive the vehicle. Have it towed to an
Authorized Mazda Dealer.
Even if the light turns off have your brake
system inspected as soon as possible by
an Authorized Mazda Dealer.NOTE
Having to add brake fluid is sometimes an
indicator of leakage. Consult an Authorized
Mazda Dealer as soon as possible even if the
brake light is no longer illuminated.
WARNING
Do not drive with the brake system
warning light illuminated. Contact an
Authorized Mazda Dealer to have the
brakes inspected as soon as possible:
Driving with the brake system
warning light illuminated is
dangerous. It indicates that your
brakes may not work at all or that
they could completely fail at any
time. If this light remains
illuminated, after checking that the
parking brake is fully released, have
the brakes inspected immediately.
qAnti-Lock Brake System (ABS)
The ABS control unit continuously
monitors the speed of each wheel. If one
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 when the ABS operates. Continue
to depress the brake pedal without
pumping the brakes.

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
lBraking 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.
lThe 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.
qABS Warning Light
The warning light stays on for a few
seconds when the ignition is switched
ON.If the ABS warning light stays on while
you're driving, the ABS control unit has
detected a system malfunction. If this
occurs, your brakes will function normally
as if the vehicle had no ABS.
Should this happen, consult an Authorized
Mazda Dealer as soon as possible.
NOTE
lWhen the engine is jump-started to charge
the battery, uneven rpm occurs and the ABS
warning light may illuminate. If this occurs,
it is the result of the weak battery and does
not indicate an ABS malfunction.
Recharge the battery.
l(With DSC vehicles)
The brake assist system does not operate
while the ABS warning light is illuminated.
qElectronic Brake Force
Distribution System Warning
If the electronic brake force distribution
control unit determines that some
components are operating incorrectly, the
control unit may illuminate the brake
system warning light and the ABS
warning light on simultaneously. The
problem is likely to be the electronic
brake force distribution system.

Manual Transaxle Operation
qManual Transaxle Shift Pattern
5-speed transaxle
6-speed transaxleNeutral position
Neutral position
The vehicle is equipped with either a 5-
speed or 6-speed manual transaxle. The
shift pattern for each is shown above.
Depress the clutch pedal all the way down
while shifting; then release it slowly.
(5-speed transaxle)
A safety feature prevents accidental
shifting from 5 to R (reverse). The shift
lever must be put in neutral before being
shifted to R.(6-speed transaxle)
Vehicles with 6-speed transaxle are
equipped with a device to prevent shifting
to R (reverse) by mistake. Push the shift
lever downward and shift to R.
WARNING
Do not use sudden engine braking on
slippery road surfaces or at high
speeds:
Shifting down while driving on wet,
snowy, or frozen roads, or while
driving at high speeds causes sudden
engine braking, which 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.
Be sure to leave the shift lever in 1 or R
position and set the parking brake
when leaving the vehicle unattended:
Otherwise the vehicle could move
and cause an accident.

CAUTION
ØKeep your foot off the clutch pedal
except when shifting gears. Also,
do not use the clutch to hold the
vehicle on an upgrade. Riding the
clutch will cause needless clutch
wear and damage.
ØDo not apply any excessive lateral
force to the gear lever when
changing from 5th to 4th gear.
This could lead to the accidental
selection of 2nd gear, which can
result in damage to the transaxle.
ØMake sure the vehicle comes to a
complete stop before shifting to R.
Shifting to R while the vehicle is
still moving may damage the
transaxle.
NOTE
If shifting to R is difficult, shift back into
neutral, release the clutch pedal, and try
again.
qRecommendations for Shifting
Upshifting
For normal acceleration, we recommend these shift
points.
Gear 5-speed transaxle 6-speed transaxle
1 to 2 21 km/h (13 mph) 24 km/h (15 mph)
2 to 3 39 km/h (24 mph) 43 km/h (27 mph)
3 to 4 55 km/h (34 mph) 56 km/h (35 mph)
4 to 5 78 km/h (49 mph) 72 km/h (45 mph)
5to6―90 km/h (56 mph)
For cruising
Gear 5-speed transaxle 6-speed transaxle
1 to 2 18 km/h (11 mph) 16 km/h (10 mph)
2 to 3 29 km/h (18 mph) 32 km/h (20 mph)
3 to 4 47 km/h (29 mph) 48 km/h (30 mph)
4 to 5 68 km/h (42 mph) 60 km/h (37 mph)
5to6―71 km/h (44 mph)
Downshifting
When you must slow down in heavy
traffic or on a steepupgrade, downshift
before the engine starts to overwork. This
reduces the chance of stalling and gives
better acceleration when you need more
speed.
On a steepdowngrade, downshifting
helps maintain safe speed and prolongs
brake life.

Automatic Transaxle Controls
Indicates that you must depress the brake pedal to shift (The ignition
must be switched to ACC or ON).
Indicates the shift lever can be shifted freely into any position.
Various Lockouts:
NOTE
The Sport AT has an option that is not included in the traditional automatic transaxle giving the
driver the option of selecting each gear instead of leaving it to the transaxle to shift gears. Even if
you intend to use the automatic transaxle functions as a traditional automatic, you should also be
aware that you can inadvertently shift into manual shift mode and an inappropriate gear may be
retained as the vehicle speed increases. If you notice the engine speed going higher or hear the
engine racing, confirm you have not accidentally slipped into manual shift mode (page 5-15).

qTransaxle Ranges
The shift lever must be in P or N to
operate the starter.
P (Park)
P locks the transaxle and prevents the
front wheels from rotating.
WARNING
Always set the shift lever to P and set
the parking brake:
Only setting the shift lever to the P
position without using the parking
brake to hold the vehicle is
dangerous. If P fails to hold, the
vehicle could move and cause an
accident.
CAUTION
ØShifting into P, N or R while the
vehicle is moving can damage
your transaxle.
ØShifting into a driving gear or
reverse when the engine is running
faster than idle can damage the
transaxle.
R (Reverse)
In position R, the vehicle moves only
backward. You must be at a complete stop
before shifting to or from R, except under
rare circumstances as explained in
Rocking the Vehicle (page 4-8).
N (Neutral)
In N, the wheels and transaxle are not
locked. The vehicle will roll freely even
on the slightest incline unless the parking
brake or brakes are on.
WARNING
If the engine is running faster than idle,
do not shift from N or P into a driving
gear:
It's dangerous to shift from N or P
into a driving gear when the engine
is running faster than idle. If this is
done, the vehicle could move
suddenly, causing an accident or
serious injury.
Do not shift into N when driving the
vehicle:
Shifting into N while driving is
dangerous. Engine braking cannot be
applied when decelerating which
could lead to an accident or serious
injury.
CAUTION
Do not shift into N when driving the
vehicle. Doing so can cause transaxle
damage.
NOTE
Apply the parking brake or depress the brake
pedal before moving the shift lever from N to
prevent the vehicle from moving unexpectedly.
D (Drive)
D is the normal driving position. From a
stop, the transaxle will automatically shift
through a 5-gear sequence.
M (Manual)
M is the manual shift mode position.
Gears can be shifted up or down by
operating the shift lever.
Refer to Manual Shift Mode (page 5-15).

qActive Adaptive Shift (AAS)
Active Adaptive Shift (AAS)
automatically controls the transaxle shift
points to best suit the road conditions and
driver input. This optimizes engine
performance and improves driving
comfort. When cornering the vehicle,
AAS mode will hold the transaxle in the
gear the vehicle was in before entering the
curve, allowing the vehicle to be
accelerated from the same gear after
exiting the curve.
If the driver accelerates rapidly, or
accelerates and decelerates rapidly by
operating the accelerator and brake pedal
for a certain period of time while the
selector lever is in the D position, AAS
mode could activate. When this occurs,
AAS mode will maintain the transaxle in
the optimum gear and the driver may
sense that the transaxle is not shifting,
however this does not indicate an
abnormality.
qShift-Lock System
The shift-lock system prevents shifting
out of P unless the brake pedal is
depressed.
To shift from P:
1. Depress and hold the brake pedal.
2. Start the engine.
3. Move the shift lever.NOTE
lWhen the ignition is switched off (LOCK),
the shift lever cannot be shifted from P.
lTo be sure the vehicle is in park,the
ignition key cannot be removed unless the
shift lever is in P.
l(With Advanced Key)
The ignition cannot be switched from ACC
to off (LOCK) when the shift lever is not in
P.
qShift-Lock Override
If the shift lever will not move from P
using the proper shift procedure, continue
to hold down the pedal.
1. Remove the shift-lock override cover
using a cloth-wrapped flat head
screwdriver.
2. Insert a screwdriver and push it down.
Cover
3. Move the shift lever.
4. Take the vehicle to an Authorized
Mazda Dealer to have the system
checked.
