CRUISE CONTROL OPERATIONS
The cruise control allows driving at a speed
between 25 to 89 MPH (40 to 144 km/h) without
keeping your foot on the accelerator pedal.
To turn on the cruise control,push the MAIN
switch on. The CRUISE indicator will come on.
To set cruising speed, accelerate your vehicle to
the desired speed, push the SET/COAST switch
and release it. (The CRUISE SET indicator will
come on in the instrument panel.) Take your foot off the accelerator pedal. Your vehicle will
maintain the set speed.
●
To pass another vehicle, depress the accel-
erator pedal. When you release the pedal,
the vehicle will return to the previously set
speed.
● The vehicle may not maintain the set speed
on winding or hilly roads. If this happens,
drive without the cruise control.
To cancel the preset speed, follow any of these
methods:
a) Push the CANCEL button. The SET indica- tor will go out.
b) Tap the brake pedal. The SET indicator will go out.
c) Move the selector lever to the N (Neutral) position. The SET indicator will go out.
d) Turn the MAIN switch off. Both the CRUISE indicator and SET indicator will go out.
●If you depress the brake pedal while pushing
the RESUME/ACCELERATE or SET/COAST
switch and reset at the cruising speed, the
cruise control will disengage. Turn the MAIN
switch off once and then turn it on again.
● The cruise control will automatically cancel if
the vehicle slows more than 8 MPH (12
km/h) below the set speed. ●
If you move the selector lever to the N
(Neutral) position, the cruise control will be
canceled.
To reset at a faster cruising speed, use one of
the following methods:
● Depress the accelerator pedal. When the
vehicle attains the desired speed, push and
release the SET/COAST switch.
● Push and hold the RESUME/ACCELERATE
switch. When the vehicle attains the speed
you desire, release the switch.
● Push, then quickly release the
RESUME/ACCELERATE switch. Each time you
do this, the set speed will increase by about
1 MPH (1.6 km/h).
To reset at a slower cruising speed, use one of
the following methods:
● Lightly tap the brake pedal. When the ve-
hicle attains the desired speed, push the
SET/COAST switch and release it.
● Push and hold the SET/COAST switch. Re-
lease the switch when the vehicle slows
down to the desired speed.
● Push, then quickly release the SET/COAST
switch. Each time you do this, the set speed
will decrease by about 1 MPH (1.6 km/h).

To resume the preset speed,push and release
the RESUME/ACCELERATE switch. The vehicle
will resume the last set cruising speed when the
vehicle speed is over 25 MPH (40 km/h). The Intelligent Cruise Control (ICC) system
maintains a selected distance from the vehicle
in front of you within the speed range of 0 to 90
MPH (0 to 144 km/h) up to the set speed. The
set speed can be selected by the driver between
20 to 90 MPH (32 to 144 km/h).
The vehicle travels at a set speed when the road
ahead is clear.
The ICC system can be set to one of two cruise
control modes.
●
Vehicle-to-vehicle distance control mode:
For maintaining a selected distance between
your vehicle and the vehicle in front of you
up to the preset speed.
● Conventional (fixed speed) cruise control
mode:
For cruising at a preset speed.WARNING
● Always drive carefully and attentively when
using either cruise control mode. Read and
understand the Owner’s Manual thoroughly
before using the cruise control. To avoid se-
rious injury or death, do not rely on the sys-
tem to prevent accidents or to control the
vehicle’s speed in emergency situations. Do
not use cruise control except in appropriate
road and traffic conditions.
● In the conventional (fixed speed) cruise con-
trol mode, a warning chime will not sound to
warn you if you are too close to the vehicle
ahead. Pay special attention to the distance
between your vehicle and the vehicle ahead
of you or a collision could occur.

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE
In the vehicle-to-vehicle distance control mode,
the Intelligent Cruise Control (ICC) system auto-
matically maintains a selected distance from
the vehicle traveling in front of you according to
that vehicle’s speed (up to the set speed), or at
the set speed when the road ahead is clear.
With ICC, the driver can maintain the same
speed as other vehicles without the constant
need to adjust the set speed as you would with
a normal cruise control system.

PRECAUTIONS ON VEHICLE-TO-
VEHICLE DISTANCE CONTROL MODE
The system is intended to enhance the opera-
tion of the vehicle when following a vehicle
traveling in the same lane and direction.
If the distance sensor
Adetects a slower
moving vehicle ahead, the system will reduce
the vehicle speed so that your vehicle follows
the vehicle in front at the selected distance.
The system automatically controls the throttle
and applies the brakes (up to 25% of vehicle
braking power) if necessary.
The detection range of the sensor is approxi-
mately 390 ft (120 m) ahead.
WARNING
● This system is only an aid to assist the driver
and is not a collision warning or avoidance
device. It is the driver’s responsibility to stay
alert, drive safely and be in control of the
vehicle at all times.
● The system is primarily intended for use on
straight, dry, open roads with light traffic. It
is not advisable to use the system in city
traffic or congested areas.
● This system will not adapt automatically to
road conditions. This system should be used
in evenly flowing traffic. Do not use the sys-
tem on roads with sharp curves, or on icy
roads, in heavy rain or in fog.
The distance 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
WARNING
● As there is a performance limit to the dis-
tance control function, never rely solely on
the Intelligent Cruise Control system. This
system does not correct careless, inatten-
tive or absent-minded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed by de-
pressing the brake pedal, depending on the
distance to the vehicle ahead and the sur-
rounding circumstances in order to maintain
a safe distance between vehicles.
● If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within the
limitations of the system. The system will
cancel once it judges that the vehicle has
come to a standstill and sound a warning
chime. To prevent the vehicle from moving,
the driver must depress the brake pedal.
● The system may not detect the vehicle in
front of you in certain road or weather condi-
tions. To avoid accidents, never use the In-
telligent Cruise Control system under the
following conditions:
– On roads where the traffic is heavy or there are sharp curves
– On slippery road surfaces such as on ice or snow, etc.
SSD0701
5-36Starting and driving

– During bad weather (rain, fog, snow, etc.)When the windshield wiper is operated at
the low speed (LO) or high speed (HI) po-
sition, the Intelligent Cruise Control sys-
tem is automatically canceled.
– When strong light (for example, at sun- rise or sunset) is directly shining on the
front of the vehicle
– When rain, snow or dirt adhere to the sys- tem sensor
– On steep downhill roads (the vehicle may go beyond the set vehicle speed and fre-
quent braking 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 frequent acceleration or
deceleration
● Do not use the Intelligent Cruise Control sys-
tem if you are towing a trailer. The system
may not detect a vehicle ahead. ●
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 dis-
tance from other vehicles using the accelera-
tor pedal. Always stay alert and avoid using
the ICC system when it is not recommended
in this section.
VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE OPERATION
Always pay attention to the operation of the
vehicle and be ready to manually control the
proper following distance. The vehicle-to-
vehicle distance control mode of the Intelligent
Cruise Control (ICC) system may not be able to
maintain the selected distance between ve-
hicles (following distance) or selected vehicle
speed under some circumstances.
The vehicle-to-vehicle distance control mode
uses a sensor
Alocated on the front of the
vehicle to detect vehicles traveling ahead. The
sensor generally detects the signals returned
from the reflectors on a vehicle ahead. There-
SSD0701
Starting and driving5-37

When driving on some roads, such as winding,
hilly, curved, narrow roads, or roads which are
under construction, the ICC sensor may detect
vehicles in a different lane, or may temporarily
not detect a vehicle traveling ahead. This may
cause the ICC system to decelerate or acceler-
ate the vehicle.
The detection of vehicles may also be affected
by vehicle operation (steering maneuver or trav-
eling position in the lane, etc.) or vehicle con-
dition.If this occurs, the ICC system may warn
you by blinking the system indicator and sound-
ing the chime unexpectedly. You will have to
manually control the proper distance away from
the vehicle traveling ahead. When driving on the freeway at a set speed and
approaching a slower traveling vehicle ahead,
the ICC will adjust the speed to maintain the
distance, selected by the driver, from the ve-
hicle ahead. If the vehicle ahead changes lanes
or exits the freeway, the ICC system will accel-
erate and maintain the speed up to the set
speed. Pay attention to the driving operation to
maintain control of the vehicle as it accelerates
to the set speed.
The vehicle may not maintain the set speed on
winding or hilly roads. If this occurs, you will
have to manually control the vehicle speed.Intelligent cruise control switch
The system is operated by a MAIN switch and
four control switches, all mounted on the steer-
ing wheel.
1. RESUME/ACCELERATE switch:
Resumes set speed or increases speed
incrementally.
2. SET/COAST switch:
Sets desired cruise speed, reduces
speed incrementally.
3. CANCEL switch:
Deactivates the system without erasing
the set speed.
