When parking on a hill, always turn the
steering wheel. When the vehicle is
headed up the hill, the front wheels should
be turned away from the curb.When facing downhill, the front wheels
should be turned into the curb.
WARNING
. Never leave unattended children
or pets in the vehicle. They could
accidentally injure themselves or
others through inadvertent op-
eration of the vehicle. Also, on
hot or sunny days, the tempera-
ture in a closed vehicle could
quickly become high enough to
cause severe or possibly fatal
injuries to people.
. Do not park the vehicle over
flammable materials such as dry
grass, waste paper or rags, as
they may burn easily if they come
near hot engine or exhaust sys-
tem parts.
. Be sure to stop the engine if you
take a nap in the vehicle. If
engine exhaust gas enters the
passenger compartment, occu-
pants in the vehicle could die
from carbon monoxide (CO) con-
tained in the exhaust gas.
CAUTION
If your vehicle has a front under-
spoiler and rear underspoiler (both
optional), pay attention to blocks and other obstructions on the
ground when parking. The under-
spoilers could be damaged by con-
tact with them.

Starting and operating
Hill start assist system (MT
models –if equipped)
CAUTION
The Hill start assist system is a
device only for helping the driver
to START the vehicle on an uphill
grade. To prevent accidents when
the vehicle is parked on a slope, be
sure to firmly set the parking brake.
When setting the parking brake,
make sure that the vehicle remains
stationary when the clutch pedal is
released.
The Hill start assist system is a device to
make starting on an uphill grade easier.
On an uphill grade, when the clutch pedal
is depressed while the brake pedal is also
depressed, braking power is maintained
temporarily by the Hill start assist system
when the brake pedal is released. The
driver is therefore able to start the vehicle
the same way as on a level grade, just
using the clutch and accelerator pedal.The Hill start assist system does not
operate when the vehicle is facing down-
hill. And the Hill start assist system may
not operate on slight grades.
When starting in reverse and using the Hill
start assist system, a braking effect may
be felt even after the brake pedal has
been released. However, this braking
effect should disappear once the clutch
pedal is released. A slight jolt may be felt when the vehicle
begins to move forward after being re-
versed.
If the braking power of the Hill start assist
system is insufficient after the brake pedal
is released, apply more braking power by
depressing the brake pedal again.
&
To activate/deactivate the Hill
start assist system (STI)
CAUTION
While the Hill start assist system is
deactivated, when starting on an
uphill grade, braking power is not
maintained if the brake pedal is
released. Start on an uphill grade
by using the parking brake.
You can activate/deactivate the Hill start
assist system according to the following
procedure.
! To deactivate
1. Stop your vehicle in a flat and safe
place and apply the parking brake.
2. Turn off the engine.

! To increase the speed (by accel-
erator pedal)
1. Depress the accelerator pedal to
accelerate the vehicle to the desired
speed.
2. Push the “SET/COAST”button once.
Now the desired speed is set and the
vehicle will keep running at that speed
without depressing the accelerator pedal.NOTEIf the difference between the actual
vehicle speed when the button is
pushed and the speed last time you
set is less than 4 mph (6.8 km/h), the
vehicle speed will be lowered by 1 mph
(1.6 km/h). This occurs because the
cruise control system unit regards this
operation as that intended to decrease
the vehicle speed. !
To decrease the speed (by button)
Push the “SET/COAST ”button and hold it
until the vehicle reaches the desired
speed. Then, release the button. The
vehicle speed at that moment will be
memorized and treated as the new set
speed.
When the difference between the actual

than 4 mph (6.8 km/h), the set speed can
be lowered 1 mph (1.6 km/h) each time by
pressing the “SET/COAST ”button quickly.
! To decrease the speed (by brake
pedal)
1. Depress the brake pedal to release
cruise control temporarily.
2. When the speed decreases to the
desired speed, press the “SET/COAST”button once. Now the desired speed is set
