WARNING
.Do not drive the vehicle with the
clutch disengaged (i.e., when the
clutch pedal is depressed) or with
the shift lever in the neutral
position. Engine braking has no
effect in either of these condi-
tions and the risk of an accident
is consequently increased.
.Do not engage the clutch (i.e.,
release the clutch pedal) sud-
denly when starting the vehicle.
By doing so the vehicle might
unexpectedly accelerate or the
transmission could malfunction.
CAUTION
Shift into reverse ONLY when the
vehicle has completely stopped. It
may cause damage to the transmis-
sion to try shifting into reverse when
the vehicle is moving.
&Shifting speeds!Recommended shifting speeds
The best compromise between fuel econ-
omy and vehicle performance during
normal driving is ensured by shifting up
at the speeds listed in the following table.
Shift up mph (km/h)
1st to 2nd 15 (24)
2nd to 3rd 25 (40)
3rd to 4th 40 (64)
4th to 5th 45 (72)
5th to 6th50 (80)
!Shift-up indicator (STI)The shift-up indicator appears to informthe driver about the upshift timing.
The shift-up indicator can be activated or
deactivated. For details, refer to“Gear
position indicator (MT models)/Shift-up
indicator (STI)”F3-34.
!Maximum allowable speeds
The following table shows the maximum
speeds that are possible with each differ-
ent gear. The tachometer’s needle will
enter the red area if these speeds are
exceeded.
With the exception of cases where sudden
acceleration is required, do not drive the
vehicle with the tachometer’s needle in-
side the red area. Failure to observe this
precaution can lead to excessive engine
wear and poor fuel economy.

&Auto modeIn the auto mode, the system estimates the
driving and road conditions using signals
from the wheel speed sensor, throttle
position sensor, steering angle sensor
and brake switch, etc. According to the
result, it electronically and automatically
controls the degree of limitation of the
differential action (LSD torque) to optimize
the differential action of the center differ-
ential. When you turn the ignition switch
ON, the“AUTO”indicator on the combina-
tion meter appears.The auto mode has 3 modes as follows.
Mode Operation
AUTO [+] This mode emphasizes traction
control and strengthens the lim-
itation of differential action that
is suitable for driving on slippery
roads for vehicle stability.
AUTO This mode is suitable for most
driving situations.
AUTO [] This mode is suitable when you
seek quick response from the
steering wheel and smooth
driving.
!Mode setting method
In most situations, it is recommended that
the“AUTO”mode is selected.Push the control switch forward to select
the“AUTO [+]”mode. After setting themode,“AUTO [+]”appears.
Pull the control switch rearward to select
the“AUTO []”mode. After setting the
mode,“AUTO []”appears.
When the“AUTO [+]”mode is selected,
pull the control switch rearward to change
to the“AUTO”mode. When the“AUTO []”
mode is set, push the control switch
forward to change to the“AUTO”mode.

Pull the switch rearward to reduce the
initial LSD torque. When the lowest posi-
tion of the driver’s control center differen-
tial indicator is displayed, the initial LSD
torque will be minimum.
CAUTION
.Do not operate the control switch
when a wheel slippage occurs.
Wait until the wheelspin has been
brought under control.
.Under any of the following condi-
tions after setting to the manual
mode, pull the center differential
control switch to minimize the
initial LSD torque:
–When a temporary spare tire is
installed–When your vehicle is towed
–When the vehicle is stopped
with the manual mode se-
lected
NOTE.A higher initial LSD torque setting
gives the vehicle greater traction when
driving straight ahead but makes cor-
nering more difficult. Remember this
when adjusting the initial LSD torque.
In general, higher initial LSD torque
settings assist driving on slippery
roads and lower settings for non-slip-
pery roads. When the vehicle is stuck in
snow or mud, setting the initial LSD
torque to the maximum will help to free
the vehicle.
.The setting of the initial LSD torque
will remain even when the auto mode is
selected or the ignition switch is turned
to the“LOCK”/“OFF”position. How-
ever, the initial LSD torque will be
minimized when the battery is discon-
nected and reconnected.
.During cornering or when making
turns (especially when going into the
garage), the rotational difference be-
tween the front and rear wheels may
cause a braking effect accompanied by
vibration and noise. This does notindicate a problem. The phenomenon
will disappear when setting the initial
LSD torque to the minimum.
In the auto mode, it controls the initial
LSD torque automatically. While in the
auto mode, this phenomenon some-
times occurs depending on the driving
condition, however, it does not indicate
a problem.
.Use the center differential indicator
only as a rough indication of the initial
LSD torque.
.If you operate the center differential
control switch while quickly accelerat-
ing or turning a tight corner, you may
feel slight shocks. This is due to
differential action by the center differ-
ential and does not indicate a problem.
&Temporary releaseWhen the driver stops the vehicle and pulls
the parking brake lever after manually
setting the initial LSD torque, the LSD
torque is temporarily minimized. However
the indicator on the combination meter
continues to show the driver’s selected
initial LSD torque. When the driver re-
leases the parking brake lever, the initial
LSD torque set by the driver is restored.

Continuously variable trans-
missionThe continuously variable transmission is
electronically controlled and provides an
infinite number of forward speeds and 1
reverse speed. It also has a manual mode.
WARNING
Do not shift from the“P”or“N”
position into the“D”or“R”position
while depressing the accelerator
pedal. This may cause the vehicle
to jump forward or backward.
CAUTION
.Observe the following precau-
tions. Otherwise, the transmis-
sion could be damaged.
–Shift into the“P”or“R”posi-
tion only after the vehicle has
completely stopped.
–Do not shift from the“D”
position into the“R”position
or vice versa until the vehicle
has completely stopped.
.Do not race the engine for more
than 5 seconds in any position
except the“N”or“P”positionwhen the brake is applied or
when chocks are used in the
wheels. This may cause the
transmission fluid to overheat.
.Never move the vehicle as fol-
lows. Doing so may result in an
unexpected accident or malfunc-
tion.
–Moving rearward by inertia
with the select lever set in a
forward driving position.
–Moving forward by inertia with
the select lever set in the“R”
position.
.When parking the vehicle, first
securely apply the parking brake
and then place the select lever in
the“P”position. Do not park for a
long time with the select lever in
any other position as doing so
could result in a dead battery.
NOTE.When the engine coolant tempera-
ture is still low, the transmission will
upshift to higher engine speeds than
when the coolant temperature is suffi-
ciently high in order to shorten the
warm-up time and improve driveability.
The gearshift timing will automaticallyshift to the normal timing after the
engine has warmed up.
.Immediately after transmission fluid
is replaced, you may feel that the
transmission operation is somewhat
unusual. This results from invalidation
of data which the on-board computer
has collected and stored in memory to
allow the transmission to shift at the
most appropriate times for the current
condition of your vehicle. Optimized
shifting will be restored as the vehicle
continues to be driven for a while.
.When driving under continuous hea-
vy load conditions such as when climb-
ing a long, steep hill, the engine speed
or the vehicle speed may automatically
be reduced. This is not a malfunction.
This phenomenon results from the
engine control function maintaining
the cooling performance of the vehicle.
The engine and vehicle speed will
return to a normal speed when the
engine is able to maintain the optimum
cooling performance after the heavy
load decreases. Take extremely care
when driving under a heavy load.
.The continuously variable transmis-
sion is a chain type system that pro-
vides superior transmission efficiency
for maximum fuel economy. At times,
depending on varying driving condi-
tions, a chain operating noise may be

heard that is characteristic of this type
of system.&Select lever1) Select lever button
: With the brake pedal depressed, shift
while pressing the select lever button
in.: Shift while pressing the select lever
button in.: Shift without pressing the select lever
button.
The select lever has four positions,“P”,
“R”,“N”,“D”and it also has an“M”position
for using the manual mode.NOTEFor some models, to protect the engine
while the select lever is in the“P”or“N”
position, the engine is controlled so
that the engine speed may not become
too high even if the accelerator pedal is
depressed hard.!P (Park)
This position is for parking the vehicle and
starting the engine. In this position, the
transmission is mechanically locked to
prevent the vehicle from rolling freely.
When you park the vehicle, first apply the
parking brake firmly, then shift into the“P”
position. Do not hold the vehicle with only
the mechanical friction of the transmission.
To shift the select lever from the“P”
position to any other position, you should
depress the brake pedal fully then move
the select lever. This prevents the vehicle
from lurching when it is started.
!R (Reverse)
This position is for backing the vehicle. To
shift from the“N”to“R”position, stop the
vehicle completely then move the lever to
the“R”position while pressing the select
lever button in.
Even when you have turned the ignition
switch to the“LOCK”/“OFF”position, you
can still move the select lever from the“N”
to“R”position for a limited time period by
depressing the brake pedal, and then it
becomes impossible. For details, refer to
“Shift lock function”F7-27.
