engine MAZDA MODEL RX 8 2008 (in English) Service Manual

Black plate (137,1)
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,
don't use the clutch to hold the
vehicle on an upgrade. Riding the
clutch will cause needless clutch
wear and damage.
Ø Make sure the vehicle comes to a
complete stop before shifting to R.
Shifting to R while the vehicle is
still moving may damage the
transmission.
NOTE
If shifting to R is difficult, shift back into
neutral, release the clutch pedal, and try
again.
q Recommendations for Shifting
Upshifting
For normal acceleration, we recommend
these shift points.
Gear Vehicle speed
1 to 2 23 km/h (14 mph)
2 to 3 35 km/h (22 mph)
3 to 4 47 km/h (29 mph)
4 to 5 58 km/h (36 mph)
5 to 6 74 km/h (46 mph)
For cruising
Gear Vehicle speed
1 to 2 23 km/h (14 mph)
2 to 3 34 km/h (21 mph)
3 to 4 45 km/h (28 mph)
4 to 5 56 km/h (35 mph)
5 to 6 68 km/h (42 mph)
Downshifting
When you must slow down in heavy
traffic or on a steep upgrade, downshift
before the engine starts to overwork. This
reduces the chance of stalling and gives
better acceleration when you need more
speed.
On a steep downgrade , downshifting
helps maintain safe speed and prolongs
brake life.

Automatic Transmission Controls
Indicates that you must depress the brake pedal to shift (The ignition
switch must be in the ACC or ON position).
Indicates the shift lever can be shifted freely into any position.
Various Lockouts:
NOTE
This Sport AT has an option that is not included in traditional automatic transmission - giving the
driver the option of selecting each gear instead of leaving it to the transmission to shift gears. Even if
you intend to use the automatic transmission 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 you change speeds. If you notice the engine speed going higher or hear the engine racing,
confirm you have not accidentally slipped into manual shift mode (page 5-14).

qTransmission Ranges
The shift lever must be in P or N to
operate the starter.
P (Park)
P locks the transmission and prevents the
rear 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 transmission.
Ø Shifting into a driving gear or
reverse when the engine is running
faster than idle can damage the
transmission.
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 4-7).
N (Neutral)
In N, the wheels and transmission 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
transmission 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 transmission will automatically
shift through a 6-gear sequence.
M (Manual)
M is the manual shift mode position.
Gears can be shifted up or down by
operating the shift lever or steering shift
switches.
Refer to Manual Shift Mode (page 5-14).

qActive Adaptive Shift (AAS)
Active Adaptive Shift (AAS)
automatically controls the transmission
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 transmission 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 transmission
in the optimum gear and the driver may
sense that the transmission 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 switch is in the LOCK
position, 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 switch cannot be turned from
the ACC position to the LOCK position
when the shift lever is not in P.
q Manual Shift Mode
This mode gives you the feel of driving a
manual transmission vehicle by operating
the shift lever and allows you to control
engine rpm and torque to the rear wheels
much like a manual transmission when
more control is desired.
To change to manual shift mode, shift the
lever from D to M.
To return to automatic shift mode, shift
the lever from M to D.
NOTE
If you change to manual shift mode when the
vehicle is stopped, the gear will shift to M1.

WARNING
Keep your hands on the steering wheel
rim when using fingers or thumbs on
the steering shift switches:Putting your hands inside the rim of
the steering wheel when using the
steering shift switches is dangerous.
If the driver air bag were to deploy in
a collision, your hands could be
impacted causing injury.
NOTE
lWhen driving slowly, the gears may not
shift up depending on vehicle speed.
lIn manual shift mode, gears do not shift up
automatically. Don't run the engine with the
tachometer needle in the RED ZONE. If the
tachometer needle enters the RED ZONE,
you may feel engine-braking because the
fuel delivery will be stopped to protect the
engine. However, this does not indicate an
abnormality.
lWhen depressing the accelerator fully, the
transmission will shift to a lower gear,
depending on vehicle speed.
Manually Shifting down
(M6 →M5 →M4 →M3 →M2 →M1)
To shift down to a lower gear, tap the shift
lever forward (
) once.
To shift down to a lower gear with the
steering shift switches, press either of the
DOWN switches away from you once
with your thumb.
DOWN switches
WARNING
Do not use 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.
Keep your hands on the steering wheel
rim when using fingers or thumbs on
the steering shift switches: Putting your hands inside the rim of
the steering wheel when using the

gives better acceleration when you need
more speed.
On a steep downgrade , downshifting
helps maintain safe speed and prolongs
brake life.
q Driving Tips
Passing
For extra power when passing another
vehicle or climbing steep grades, depress
the accelerator fully. The transmission will
shift to a lower gear, depending on vehicle
speed.
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.

Power Steering
Power steering is only operable when the
engine is running. If the engine is off or if
the power steering system is inoperable,
you can still steer, but it requires more
physical effort.
If the steering feels stiffer than usual
during normal driving, consult an
Authorized Mazda Dealer.
NOTE
The steering may feel rigid if you continuously
attempt to steer when the vehicle is stopped or
moving extremely slowly. This has been
designed to protect the system and doesn't
indicate a malfunction. If you don't attempt to
steer for a minute, power steering will be
restored.
qPower Steering Malfunction
Indicator Light
This indicator light illuminates when the
ignition switch is turned to the ON
position and goes off when the engine is
started.
If this light illuminates while driving, it
indicates a malfunction of the power
steering system. Consult an Authorized
Mazda Dealer. NOTE
The power steering system is inoperable when
the power steering malfunction indicator light
illuminates. Steering is possible, but requires
more physical effort.

lPress the CANCEL button.
The system is off when the ignition is off.
NOTE
Cruise control will cancel at about 15 km/h (9
mph) below the preset speed (such as may
happen when climbing a long, steep grade) or
below 30 km/h (19 mph).
Traction Control System
(TCS)
í
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
without causing them to spin and lose
traction.
WARNING
Do not rely on the traction control
system 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 on the rear
wheels only 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.
NOTE
To turn off the TCS, press the DSC OFF switch
(page 5-26).

qTCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition switch is turned
to the ON position. If the TCS or DSC is
operating, the indicator light flashes.
If the light stays on, the TCS or DSC may
have a malfunction and they may not
operate correctly. Take your vehicle to an
Authorized Mazda Dealer.
NOTE
lIn addition to the indicator light flashing, a
slight lugging sound will come from the
engine. This indicates that the TCS is
operating properly.
lOn slippery surfaces, such as fresh snow, it
will be impossible to achieve high rpm
when the TCS is on.
Dynamic Stability Control
(DSC)
í
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 5-8) and TCS (page
5-23).
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.

qDSC OFF Switch
Press the DSC OFF switch to turn off the
TCS/DSC. The DSC OFF indicator light
will illuminate.
Press the switch again to turn the TCS/
DSC back on. The DSC OFF indicator
light will go out. NOTE
lWhen DSC 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 difficult.
When this happens, turn off the TCS/DSC.
lIf the TCS/DSC is off when the engine is
turned off, it automatically activates when
the ignition switch is turned on.
lLeaving the TCS/DSC on will provide the
best stability. When the TCS/DSC is off, the
TCS/DSC does not activate but the brake
LSD (Limited Slip Differentials) function
remains.
lIf the DSC OFF switch is pressed and held
for a second or more, the TCS/DSC system
may become inoperative due to the system
detecting switch trouble. If the TCS/DSC
system becomes inoperative, the TCS/DSC
and the DSC OFF indicator lights
illuminate simultaneously. In this case, turn
off the engine and restart it to restore the
TCS/DSC.
