left in this condition, the battery
may be discharged.
NOTE Although you can stop the engine by
operating the push-button ignition
switch, do not stop the engine during
driving except in an emergency.
& When access key does not
operate properly
Refer to “ Access key – if access key does
not operate properly ” F 9-16.Remote engine start system
(dealer option) WARNING. There are some general precau-
tions when starting the engine.
Carefully read the precautions
described in “ General precau-
tions when starting engine ” F 7-
9.
. Do not remote start a vehicle in
an enclosed environment (e.g.
closed garage). Prolonged opera-
tion of a motor vehicle in an
enclosed environment can cause
a harmful build-up of Carbon
Monoxide. Carbon Monoxide is
harmful to your health. Exposure
to high levels of Carbon Monox-
ide can cause headaches, dizzi-
ness or in extreme cases uncon-
sciousness and/or death.
. Before performing any servicing
of the vehicle, temporarily place
the remote engine start system in
service mode to prevent the
system from unexpectedly start-
ing the engine.
The remote engine start system allows7-14

you to start the engine from outside the
vehicle. In addition, the remote engine
start system can activate the heater or air
conditioner, providing you with a comfor-
table cabin upon entry.
NOTE The length of time for which it is
acceptable to allow the engine to
remain idling may be governed by local
laws and regulations. Check the local
rules when using the remote engine
start system. & Models with “ keyless access

placing battery of access key ” F 11-50.7-16

The auto mode has 3 modes as follows. Mode Operation
AUTO [+] This mode emphasizes traction
control and strengthens the
limitation of differential action
that is suitable for driving on
slippery roads for vehicle stabi-
lity.
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 the
mode, “ 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.& Manual mode
In the manual mode, you can use the
center differential control switch to adjust
the initial LSD torque as desired. When
this mode is selected, the “ AUTO ” indica-
tor disappears.Starting and operating/Driver ’ s Control Center Differential (C.DIFF/DCCD) (STI)
– CONTINUED –7-21

– 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 not
indicate 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 release When the driver stops the vehicle and
pulls the parking brake lever after manu-
ally 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-
mission The continuously variable transmission is
electronically controlled and provides an
infinite number of forward speeds and 1
reverse speed. It also has a manual mode.
WARNINGDo 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. Shift into the “ P ” or “ R ” position
only after the vehicle is comple-
tely stopped. Shifting while the
vehicle is moving may cause
damage to the transmission.
. Do not race the engine for more
than 5 seconds in any position
except the “ N ” or “ P ” position
when the brake is applied or
when chocks are used in the
wheels. This may cause the
transmission fluid to overheat.
. Never move the vehicle rearwardStarting and operating/Continuously variable transmission
– CONTINUED –7-23

Starting and operating/Continuously variable transmission
by inertia with the select lever set
in a forward position or move the
vehicle forward by inertia with
the select lever set in the reverse
position. Doing so may result in
an unexpected accident or mal-
function.
. Do not shift from the “ D ” position
into the “ R ” position or vice
versa until the vehicle has com-
pletely stopped. Such shifting
may cause damage to the trans-
mission.
. 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 automatically
shift 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 a CVT model under
continuous heavy load conditions such
as when climbing 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 main-
taining 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. Driving under a heavy
load must be performed with extreme
care.
. The continuously variable transmis-
sion is a chain type system that
provides superior transmission effi-
ciency for maximum fuel economy. At
times, depending on varying driving
conditions, a chain operating noise
may be heard that is characteristic of this type of system.
& Select lever
1) Select lever button7-24

: 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.
NOTE For 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 transmis-
sion.
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.
When the ignition switch has been turned
to the “ LOCK ” / “ OFF ” position, movement
of the select lever from the “ N ” to “ R ”
position is possible for a limited time
period by depressing the brake pedal,
and then it becomes impossible. For
details, refer to “ Shift lock function ” F 7-27. ! N (Neutral)
This position is for restarting a stalled
engine. In this position, the transmission is
neutral, meaning that the wheels and
transmission are not locked. Therefore,
the vehicle will roll freely, even on the
slightest incline unless the parking brake
or foot brake is applied.
Avoid coasting with the transmission in
neutral. Engine braking has no effect in
this condition.
WARNINGDo not drive the vehicle with the
select lever in the “ N ” (neutral)
position. Engine braking has no
effect in this condition and the risk
of an accident is consequently in-
creased.
NOTE If the select lever is in the “ N ” position
when you stop the engine for parking,
you may not subsequently be able to
move it to the “ R ” and “ P ” positions. If
this happens, turn the ignition switch to
the “ ON ” position. You will then be able
to move the select lever to the “ P ”
position.Starting and operating/Continuously variable transmission
