Recommendations for shifting
Upshifting
For normal acceleration and cruising, Mazda recommends these shift points:

Gear Vehicle speed *1
M1 to M2 24 km/h (15 mph)
M2 to M3 40 km/h (25 mph)
M3 to M4 65 km/h (40 mph)
M4 to M5 73 km/h (45 mph)
M5 to M6 81 km/h (50 mph)
*1 Always observe local speed limit regulations.


Downshifting
When you must slow down in heavy traf¿ c or on a steep upgrade, downshift before the
engine starts to overwork. This gives better acceleration when you need more speed.

On a steep downgrade, downshifting helps maintain safe speed and prolongs brake life.

Driving Tips
WARNING
Do not let the vehicle move in a
direction opposite to the direction
selected by the selector lever:
Do not let the vehicle move backward
with the selector lever in a forward
position, or do not let the vehicle
move forward with the selector lever
in the reverse position. Otherwise, the
engine may stop, causing the loss of
the power brake and power steering
functions, and make it diffi cult to
control the vehicle which could result
in an accident.

Passing
For extra power when passing another
vehicle or climbing steep grades, depress
the accelerator fully. The transaxle will
shift to a lower gear, depending on vehicle
speed.
N O T E
(Some models)
The accelerator pedal may initially feel
heavy as it is being depressed, then feel
lighter as it is depressed further. This
change in pedal force aids the engine
control system in determining how much
the accelerator pedal has been depressed
for performing kickdown, and functions to
control whether or not kickdown should be
performed.

Climbing steep grades from a stop
To climb a steep grade from a stopped
position:

1. Depress the brake pedal.
2. Shift to D or M1, depending on the
load weight and grade steepness.
3. Release the brake pedal while gradually
accelerating.

Descending steep grades
When descending a steep grade, shift to
lower gears, depending on load weight and
grade steepness. Descend slowly, using the
brakes only occasionally to prevent them
from overheating.

Switches and Controls
CAUTION
 


¾ Do not shade the light sensor by adhering a sticker or a label on the windshield. Otherwise
the light sensor will not operate correctly.

 


¾ The light sensor also works as a rain sensor for the auto-wiper control. Keep hands and
scrapers clear of the windshield when the wiper lever is in the
position and the
ignition is switched ON as fi ngers could be pinched or the wipers and wiper blades could be
damaged when the wipers activate automatically. If you are going to clean the windshield,
be sure the wipers are turned off completely when it is particularly tempting to leave the
engine running. This is particularly important when clearing ice and snow.

N O T E
 


y The headlights, other exterior lights and dashboard illumination may not turn off
immediately even if the surrounding area becomes well-lit because the light sensor
determines that it is night time if the surrounding area is continuously dark for several
minutes such as inside long tunnels, traf¿ c jams inside tunnels, or in indoor parking lots.

 In this case, the lights turn off if the light switch is turned to the position.



y (Without auto headlight off function) 
 When the headlight switch is in the position and the ignition is switched to ACC or
the ignition is switched off, the headlights, other exterior lights and dashboard
illumination will turn off.
 


y The dashboard illumination can be adjusted by rotating the knob in the instrument cluster.
Also, the day/night mode can be changed by rotating the knob until a beep sound is heard.
To adjust the brightness of the dashboard illumination:
  Refer to Dashboard Illumination on page 4-19 .



y The sensitivity of the AUTO lights may be changed by an Authorized Mazda Dealer.
 Refer to Personalization Features on page 9-10 .

When Driving
Switches and Controls
Auto-wiper control
When the wiper lever is in the

position, the rain sensor senses the amount
of rainfall on the windshield and turns the
wipers on or off automatically (off—
intermittent—low speed—high speed).

The sensitivity of the rain sensor can be
adjusted by turning the switch on the
wiper lever.
From the center position (normal), rotate
the switch upward for higher sensitivity
(faster response) or rotate it downward for
less sensitivity (slower response).

CAUTION
 


¾ Do not shade the rain sensor by
adhering a sticker or a label on the
windshield. Otherwise the rain sensor
will not operate correctly.
 

 


¾ When the wiper lever is in the
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
 


¾ If the windshield above the rain
sensor is touched or wiped with a
cloth.
 


¾ If the windshield is struck with a hand
or other object from either outside or
inside the vehicle.
  Keep hands and scrapers clear of the
windshield when the wiper lever is in the

position and the ignition is
switched ON as fi ngers could be pinched
or the wipers and wiper blades damaged
when the wipers activate automatically.
  If you are going to clean the windshield,
be sure the wipers are turned off
completely (when it is most likely
that the engine is left running) this is
particularly important when clearing ice
and snow.

When Driving
Brake
B r a k e S y s t e m
Foot Brake
This vehicle 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 , fi nd a safe place to stop:
Coasting with the engine stalled or
turned off is dangerous. Braking will
require more eff ort, 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 off brakes that have become
wet by driving slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the 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 aff ected.

CAUTION




¾ Do not drive with your foot held on the
brake pedal. Doing so could result in the
following:
 


¾ The brake parts will wear out more
quickly.
 


¾ The brakes can overheat and
adversely aff ect brake performance.




¾ 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 insuffi cient braking
operation.
 

 


¾ Wear shoes appropriate for driving in
order to avoid your shoe contacting
the brake pedal when depressing the
accelerator pedal.

When Driving
ABS/TCS/DSC
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 Warning Lights on page 4-25 .
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.

N O T E
 


y 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.
 


y 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.

4–59
When Driving
ABS/TCS/DSC
Traction Control System
(TCS)
The Traction Control System (TCS)
enhances traction and safety by controlling
engine torque and braking. When the TCS
detects driving wheel slippage, it lowers
engine torque and operates the brakes to
prevent loss of traction.

This means that on a slick surface, the
engine adjusts automatically to provide
optimum power to the drive wheels,
limiting wheel spin and loss of traction.

The warning light turns on when the
system has a malfunction.
Refer to Warning Lights on page 4-25 .
WARNING
Do not rely on the Traction Control
System (TCS) as a substitute for safe
driving:
The Traction Control System ( TCS)
cannot compensate for unsafe and
reckless driving, excessive speed,
tailgating (following another vehicle
too closely), and hydroplaning
(reduced tire friction and road contact
because of water on the road surface).
You can still have an accident.

Use snow tires or tire chains and drive at
reduced speeds when roads are covered
with ice and/or snow:
Driving without proper traction devices
on snow and/or ice-covered roads
is dangerous. The Traction Control
System ( TCS) alone cannot provide
adequate traction and you could still
have an accident.

N O T E
To turn off the TCS, press the TCS OFF
switch (page 4-60 ).

TCS/DSC Indicator Light

This indicator light stays on for a few
seconds when the ignition is switched
ON. If the TCS or DSC is operating, the
indicator light À ashes.

If the light stays on, the TCS, DSC
or the brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an
Authorized Mazda Dealer.
N O T E
 


y In addition to the indicator light
À ashing, a slight lugging sound will
come from the engine. This indicates
that the TCS/DSC is operating properly.
 


y On slippery surfaces, such as fresh
snow, it will be impossible to achieve
high rpm when the TCS is on.

TCS OFF Indicator Light

This indicator light stays on for a few
seconds when the ignition is switched ON.
It also illuminates when the TCS OFF
switch is pressed and TCS is switched off.
Refer to TCS OFF Switch on page 4-60 .

If the light remains illuminated and the
TCS is not switched off, take your vehicle
to an Authorized Mazda Dealer. The DSC
may have a malfunction.
TCS OFF Switch
Press the TCS OFF switch to turn off the
TCS. The TCS OFF indicator light in the
instrument cluster will illuminate.


Press the switch again to turn the TCS
back on. The TCS OFF indicator light will
turn off.
N O T E
 


y When TCS is on and you attempt to free
the vehicle when it is stuck, or drive
it out of freshly fallen snow, the TCS
(part of the DSC system) will activate.
Depressing the accelerator will not
increase engine power and freeing
the vehicle may be dif¿ cult. When this
happens, turn off the TCS.
 


y If the TCS is off when the engine is
turned off, it automatically activates
when the ignition is switched ON.
 


y Leaving the TCS on will provide the
best traction.
 


y If the TCS OFF switch is pressed and
held for 10 seconds or more, the TCS
OFF switch malfunction detection
function operates and the TCS system
activates automatically. The TCS OFF
indicator light turns off while the TCS
system is operative.

When Driving
ABS/TCS/DSC
Dynamic Stability
Control (DSC)
The Dynamic Stability Control (DSC)
automatically controls braking and engine
torque in conjunction with systems such
as ABS and TCS to help control side slip
when driving on slippery surfaces, or
during sudden or evasive maneuvering,
enhancing vehicle safety.

Refer to ABS (page 4-58 ) and TCS
(page 4-59 ).

DSC operation is possible at speeds
greater than 20 km/h (12 mph).

The warning light turns on when the
system has a malfunction.
Refer to Warning Lights on page 4-25 .
WARNING
Do not rely on the Dynamic Stability
Control as a substitute for safe driving:
The Dynamic Stability Control (DSC)
cannot compensate for unsafe and
reckless driving, excessive speed,
tailgating (following another vehicle
too closely), and hydroplaning
(reduced tire friction and road contact
because of water on the road surface).
You can still have an accident.

CAUTION
 


¾ The DSC may not operate correctly
unless the following are observed:
 


¾ Use tires of the correct size specifi ed
for your Mazda on all four wheels.
 


¾ Use tires of the same manufacturer,
brand and tread pattern on all four
wheels.
 


¾ Do not mix worn tires. 



¾ The DSC may not operate correctly when
tire chains are used or a temporary spare
tire is installed because the tire diameter
changes.
