OPERATING RANGE FOR EN-
GINE START FUNCTION
The Intelligent Key can only be used for
starting the engine when the Intelligent Key
is within the specified operating range.
When the Intelligent Key battery is almost
discharged or strong radio waves are pre-
sent near the operating location, the Intelli-
gent Key system’s operating range becomes
narrower and may not function properly.
If the Intelligent Key is within the operating
range, it is possible for anyone, even some-
one who does not carry the Intelligent Key,
to push the ignition switch to start the
engine..
The trunk area is not included in the
operating range but the Intelligent Key
may function.
. If the Intelligent Key is placed on the
instrument panel, rear parcel shelf, inside
the glove box or door pocket, the
Intelligent Key may not function.
. If the Intelligent Key is placed near the
door or window outside the vehicle, the
Intelligent Key may function.

PUSH-BUTTON IGNITION
SWITCH OPERATION
When the ignition switch is pushed without
depressing the brake pedal, the ignition
switch position will change as follows:
. Push center once to change to ACC.
. Push center two times to change to ON.
. Push center three times to change to
OFF. (No position illuminates.)
. Push center four times to return to ACC.
. Open or close any door to return to
LOCK during the OFF position.
If the battery of the vehicle is discharged,
the push-button ignition switch cannot be
turned from the LOCK position.

— On roads where the traffic isheavy or there are sharp curves
— On slippery road surfaces such as on ice or snow, etc.
— During bad weather (rain, fog, snow, etc.)
— When rain, snow or dirt adhere to the system sensor
— On steep downhill roads (the vehicle may go beyond the set
vehicle speed and frequent brak-
ing may result in overheating the
brakes)
— On repeated uphill and downhill roads
— When traffic conditions make it difficult to keep a proper distance
between vehicles because of fre-
quent acceleration or deceleration
. In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. You
may need to control the distance
from other vehicles using the accel-
erator pedal. Always stay alert and
avoid using the ICC system when it is
not recommended in this section. The radar sensor will not detect the follow-
ing objects:
.
Stationary and slow moving vehicles
. Pedestrians or objects in the roadway
. Oncoming vehicles in the same lane
. Motorcycles traveling offset in the travel
lane
The sensor generally detects the signals
returned from the vehicle ahead. Therefore,
if the sensor cannot detect the reflection
from the vehicle ahead, the ICC system may
not maintain the selected distance.
The following are some conditions in which
the sensor cannot detect the signals:
. When the snow or road spray from
traveling vehicles reduces the sensor’s
visibility
. When excessively heavy baggage is
loaded in the rear seat or the trunk of
your vehicle
The ICC system is designed to automatically
check the sensor’s operation within the
limitation of the system. When the sensor
is covered with dirt or is obstructed, the
system will automatically be canceled. If the
sensor is covered with ice, a transparent or
translucent vinyl bag, etc., the ICC system
may not detect them. In these instances, the
vehicle-to-vehicle distance control mode
may not cancel and may not be able to
maintain the selected following distance from the vehicle ahead. Be sure to check
and clean the sensor regularly.

DCA SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
of the DCA system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
.This system will not adapt automati-
cally to road conditions. Do not use
the system on roads with sharp
curves, or on icy roads, in heavy rain
or in fog.
. The DCA system will not apply brake
control while the driver’s foot is on
the accelerator pedal.
. As there is a performance limit to the
distance control function, never rely
solely on the DCA system. This sys-
tem does not correct careless, inat-
tentive or absent-minded driving, or
overcome poor visibility in rain, fog,
or other bad weather. Decelerate the
vehicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing circumstances in order to main-
tain a safe distance between vehicles. .
The system may not detect the
vehicle in front of you in certain road
or weather conditions. To avoid ac-
cidents, never use the DCA system
under the following conditions:
— On roads with sharp curves
— On slippery road surfaces such as on ice or snow, etc.
— During bad weather (rain, fog, snow, etc.)
— When rain, snow or dirt adhere to the system sensor
— On steep downhill roads (fre- quent braking may result in over-
heating the brakes)
— On repeated uphill and downhill roads
. In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. You
may need to control the distance
from other vehicles using the accel-
erator pedal. Always stay alert and
avoid using the DCA system when it
is not recommended in this section. The radar sensor will not detect the follow-
ing objects:
.
Stationary and slow moving vehicles
. Pedestrians or objects in the roadway
. Oncoming vehicles in the same lane
. Motorcycles traveling offset in the travel
lane
The following are some conditions in which
the sensor cannot detect the signals:
. When the snow or road spray from
traveling vehicles reduces the sensor’s
visibility
. When excessively heavy baggage is
loaded in the rear seat or the trunk room
