or speed up to maintain the select-
ed distance. If the vehicle ahead speeds up,
your vehicle will travel at a steady
cruising speed after accelerating to
the set speed. (Continued)
If the warning chime sounds,
depress the accelerator or
brake pedal to actively adjust
the vehicle speed, and the dis-
tance to the vehicle ahead.
Even if the warning chime is
not activated, always pay

In traffic situation
In traffic, your vehicle will stop if the
vehicle ahead of you stops. Also, if
the vehicle ahead of you starts mov-
ing, your vehicle will start as well.
However, if the vehicle stops for
more than 3 seconds, you must
depress the accelerator pedal or
push up the lever (RES+) to start
driving.
Sensor to detect distance to
the vehicle ahead
The Smart Cruise Control uses a
sensor to detect distance to the vehi-
cle ahead.

Limitations of the system
The Smart Cruise Control System
may have limits to its ability to detect
distance to the vehicle ahead due to
road and traffic conditions.
On curves
The Smart Cruise Control Systemmay not detect a moving vehicle in
your lane, and then your vehicle
could accelerate to the set speed.
Also, the vehicle speed will
decrease when the vehicle ahead
is recognized suddenly.
Select the appropriate set speed on curves and apply the brakes or
accelerator pedal if necessary. Your vehicle speed can be reduced
due to a vehicle in the adjacent lane.
Apply the accelerator pedal and
select the appropriate set speed.
Check to be sure that the road con-
ditions permit safe operation of the
Smart Cruise Control.

On inclines
During uphill or downhill driving,the Smart Cruise Control System
may not detect a moving vehicle in
your lane, and cause your vehicle
to accelerate to the set speed.
Also, the vehicle speed will rapidly
decrease when the vehicle ahead
is recognized suddenly.
Select the appropriate set speed on inclines and apply the brake or
accelerator pedal if necessary.
Lane changing
A vehicle which moves into yourlane from an adjacent lane cannot
be recognized by the sensor until it
is in the sensor's detection range.
The sensor may not detect imme- diately when a vehicle cuts in sud-
denly. Always pay attention to the
traffic, road and driving conditions.
If a slower vehicle moves into your lane, your speed may decrease to
maintain the distance to the vehicle
ahead.
If a faster vehicle which moves into your lane, your vehicle will acceler-
ate to the set speed.
Vehicle recognition
Some vehicles in your lane cannot
be recognized by the sensor:
- Narrow vehicles such as motorcy-cles or bicycles
- Vehicles offset to one side
- Slow-moving vehicles or sudden- decelerating vehicles
- Stopped vehicles
- Vehicles with small rear profile such as trailers with no loads

Driving your vehicle
A vehicle ahead cannot be recog-
nized correctly by the sensor if any of
following occurs:
- When the vehicle is pointing upwards due to overloading in the
trunk
- While the steering wheel is operat- ing
- When driving to one side of the lane
- When driving on narrow lanes or on curves
Apply the brake or accelerator pedal
if necessary. Your vehicle may accelerate when
a vehicle ahead of you disappears.
When you are warned that the vehicle ahead of you is not detect-
ed, drive with caution. When vehicles are at a standstill
and the vehicle in front of you
changes to the next lane, be care-
ful when your vehicle starts to
move because it may not recog-
nize the stopped vehicle in front of
you.

Always look out for pedestrianswhen your vehicle is maintaining a
distance with the vehicle ahead. Always be cautious for vehicles
with higher height or vehicles car-
rying loads that sticks out from the
back of the vehicle.

When using the Smart Cruise
Control take the following pre-
cautions:
If an emergency stop is nec-
essary, you must apply the
brakes. The vehicle cannot be
stopped at every emergency
situation by using the Smart
Cruise Control System.
Keep a safe distance accord-
ing to road conditions and
vehicle speed. If the vehicle to
vehicle distance is too close
during a high-speed driving, a
serious collision may result.
Always maintain sufficient
braking distance and deceler-
ate your vehicle by applying
the brakes if necessary.

Driving in the rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or
on slick pavement:
Slow down and allow extra follow-ing distance. A heavy rainfall
makes it harder to see and increas-
es the distance needed to stop
your vehicle.
Turn OFF your Cruise Control. (if equipped)
Replace your windshield wiper blades when they show signs of
streaking or missing areas on the
windshield.
Be sure your tires have enough tread. If your tires do not have
enough tread, making a quick stop
on wet pavement can cause a skid
and possibly lead to an accident.
Refer to "Tire Tread" in chapter 7.
Turn on your headlamps to make it easier for others to see you.
Driving too fast through large pud- dles can affect your brakes. If you
must go through puddles, try to
drive through them slowly. If you believe your brakes may be
wet, apply them lightly while driv-
ing until normal braking operation
returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the
water. The best advice is SLOW
DOWN when the road is wet. The
risk of hydroplaning increases as the
depth of tire tread decreases. (Refer
to "Tire Tread" in chapter 7.)
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.

Snow or icy conditions
You need to keep sufficient distance
between your vehicle and the vehicle
in front of you.
Apply the brakes gently. Speeding,
rapid acceleration, sudden brake
applications, and sharp turns are
potentially very hazardous practices.
During deceleration, use engine
braking to the fullest extent. Sudden
brake applications on snowy or icy
roads may cause skids to occur.
To drive your vehicle in deep snow, it
may be necessary to use snow tires
or to install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to
carry include tire chains, tow straps
or chains, a flashlight, emergency
flares, sand, a shovel, jumper cables,
a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.

chain) on the rear tires for 2WD
vehicles or on all four tires for
AWD vehicles. It should be noted
that installing AutoSock
®(fabric
snow chain) on the tires will pro-
vide a greater driving force, but
will not prevent side skids.
• Do not install studded tires with- out first checking local, state and
municipal regulations for possible
restrictions against their use. Chain Installation
When installing AutoSock®(fabric
snow chain), follow the manufactur-
er's instructions and mount them as
tightly possible. Drive slowly (less
than 20 mph (30 km/h)) with chains

tacting the body or chassis, stop and
tighten them. If they still make con-
tact, slow down until the noise stops.
Remove the AutoSock
®(fabric snow
chain) as soon as you begin driving
on cleared roads.
When mounting AutoSock
®(fabric
snow chain), park the vehicle on
level ground away from traffic. Turn
on the vehicle Hazard Warning
Flasher and place a triangular emer-
gency warning device behind the
vehicle (if available).
