Cautions
 Do not rely too much on dynamic radar cruise control. Vehicletovehicle distance control has its limitations.
Always remain aware of the distance from the vehicle ahead and other veh\
icles. If necessary, depress the brake pedal to ensure
sufficient distance.
 Dynamic radar cruise control is not a collisionavoidance system.
If necessary, depress the brake pedal to ensure sufficient distance.
 Dynamic radar cruise control should not be used in the following conditi\
ons:
In bad weather (such as rain, fog, snow, sandstorms)
 Raindrops or snowflakes get in the millimeter wave radar sensor or the g\
rille cover
 On the roads in heavy traffic or at sharp bends
 On slippery road surfaces (icy or snow− covered road surfaces)
 On steep downhill slopes
 Acceleration or deceleration must be repeated
 On roads with steep and short inclines and declines
In any conditions of the above, an appropriate vehicle −to− vehicle distance control
may not be attained.
 This system is not provided to justify careless driving.
Always remain aware of the distance from the vehicle ahead and other veh\
icles.
 The dynamic radar cruise control should not be used when exiting from,
or when entering or merging onto a freeway.
When you are following a slower moving vehicle and exiting, the sensor d\
oes not detect
the vehicle and will accelerate to preset speed.

Warning Display
If there is trouble somewhere in the dynamic radar cruise control while th\
e vehicle −to− vehicle distance control mode is on, the “CRUISE”
indicator light in the instrument cluster flashes, the master warning light comes \
on and the warning tone sounds, and one or mo re of the
warning messages will appear on the multi −information display.
If a warning message appears on the display, take the appropriate measure referring to Section 3 −1, “Owner’s Manual”.
 Approach Warning
Dynamic radar cruise control and approach warning do not operate when the vehicl\
e ahead is at a stop
or is driving much slower than your vehicle. Use caution for the vehicle at the end of the line in heavy
traffic or at the tollgate, the vehicle at a stop and the very slow vehicle.
If your vehicle approaches the vehicle ahead because of insufficient braking when the vehicle ahead deceler-
ates abruptly or when another vehicle cuts in ahead of you, the multi −information display flashes and beeps.
Depress the brake pedal to slow down, ensuring sufficient vehicle −to− vehicle distance.
Warning message
“CLEAN RADAR SENSOR”
 “CRUISE NOT AVAILABLE”
 “CHECK CRUISE SYSTEM”
If any warning message shown above appears, the preset
speed automatically cancels out.

Depress the accelerator or brake pedal to attain the desired speed.
 Press the control lever downward in the “– SET” direction and r\
elease it.
This sets the vehicle at that speed.
If a vehicle is detected ahead of you: Your cruising speed changes in proportion to the speed
of the vehicle ahead to maintain an appropriate distance from your vehic\
le to the vehicle ahead.
If there was no vehicle ahead, your cruising speed will be gradually inc\
reased up to the preset speed.
If no vehicle is detected ahead of you: Your cruising speed is
maintained at the preset speed.
 Cancelling
To stop the operation: Push the “ON −OFF” button to turn off.
To stop the operation temporarily:
Pull the control lever in the “CANCEL” direction.
To resume follow −up cruising or cruising at fixed speed,
press the control lever upward and release it.

Operation Procedure
 Acceleration/Deceleration
To accelerate: Depress the accelerator pedal. (When you release the accelerator ped\
al, follow −up cruising or fixed speed cruising
resumes.) If there was no vehicle ahead, the vehicle will accelerate gradually to the\
preset speed. At this time, depressing the acceler-
ator pedal will accelerate quickly.
To decelerate: Depress the brake pedal. (Even when you release the brake pedal, dyn\
amic radar cruise control does not return
to follow− up cruising or fixed speed cruising. Press the control lever upward to \
resume follow− up−cruising or fixed speed cruising.)
 Changing the preset speed
Using the control lever:
 Press the control lever upward or downward.
Press the control lever upward in the “+RES” direction to increase\

the preset speed. The displayed speed will increase in increments of 5 \
mph
(for U.S.A) or 5 km/h (for Canada).
 Press the control lever downward in the “– SET” direction to de\
crease
the preset speed. The displayed speed will decrease in decrements
of 5 mph (for U.S.A.) or 5 km/h (for Canada).
 Release the control lever when the multi −information display shows
the desired preset speed.
Using the accelerator and brake pedals:
 When using the accelerator pedal, you need to cancel the preset speed on\
ce.
 Depress the accelerator or brake pedal to attain the desired speed.
 Press the control lever downward in the “– SET” direction and
release the lever.
