Precaution for Brak e Control SystemINFOID:0000000006222557
 Slight vibrations are felt on the brake pedal and the operation noises occur, when VDC function, TCS func-
tion, ABS function, EBD function, hill start assist function or brake limited slip differential (BLSD) function
operates. This is not a malfunction because it is caus ed by VDC function, TCS function, ABS function, EBD
function, hill start assist function or brake limited sl ip differential (BLSD) function that is normally operated.
 When starting engine or when starting vehicle just after starting engine, brake pedal may vibrate or motor
operating noise may be heard from engine compartment. This is normal condition.
 Brake stopping distance may become longer than models without ABS function depending on the road con-
ditions, when ABS function is operated on slippery r oad like rough road, gravel road or snowy road.
 When a malfunction is indicated, always collect info rmation from the customer about conditions of occur-
rence, estimate cause and perform operation. Check brake booster operation, brake fluid level and brake
fluid leakage, as well as electrical system.
 The optimum performance is achieved by control for V DC function, TCS function, ABS function, EBD func-
tion, hill start assist function or brake limited slip di fferential (BLSD) function when all of brakes, suspensions

Precautions for Vehicle-to-V ehicle Distance Control ModeINFOID:0000000006224276
 ICC 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 safe ly 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 condi tions. This system should be used in evenly flowing
traffic. Do not use the system on roads with sharp curves, or on icy roads, in heavy rain or in fog.
 The ICC sensor will not detect under most conditions.
- Stationary and slow moving vehicles.
- Pedestrians or objects in the roadway.
- Oncoming vehicles in the some lane.
- Motorcycles traveling offset in the travel lane.
 As there is a performance limit to the distance contro l function, never rely solely on the ICC system. This
system does not correct careless, inattentive 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 surrounding circumstances in order to maintain a safe distance
between vehicles.
 If the vehicle ahead comes to a stop, the vehicle decelerat es to a standstill within the limitations of the sys-
tem. 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 movi ng, the driver must depress the brake pedal.
 The system may not detect the vehicle in front of the dr iver in certain road or weather conditions. To avoid
accidents, never use the ICC syst em 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.
- On off-road surfaces such as on sand or rock, etc.
- During bad weather (rain, fog, snow, etc.)
- When the windshield wipers are operating at high speed. The ICC system may cancel when the wipers are
set to the AUTO position.
- When strong light (for example, at sunrise or sunset ) is directly shining on the front of the vehicle.
- 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 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.
- When towing a trailer or other vehicle
 In some road or traffic conditions, a vehicle or object can unexpectedly come into the sensor detection zone and cause automatic braking. The driver may need to c ontrol the distance from other vehicles using the
accelerator pedal. Always stay alert and avoid using t he ICC system when it is not recommended in this sec-
tion.
 The vehicle-to-vehicle distance control mode uses a sensor located on the front of the vehicle to detect vehi-
cles traveling ahead. The sensor generally detects t he signals returned from the reflectors on a vehicle
ahead. Therefore, if the sensor c annot detect the reflector on the v ehicle 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 reflector of the vehicle ahead is positioned high on the vehicle (trailer, etc.).
- When the reflector on the vehicle ahead is missing, damaged or covered.
- When the reflector of the vehicle ahead is covered with dirt, snow and road spray.
- When the snow or road spray from traveling vehicles reduces the sensor's visibility.
- When dense exhaust or other smoke (black smoke) fr om vehicles reduces the sensor's visibility.
- When excessively heavy baggage is loaded in the rear seat or the luggage room of own vehicle.
- When the vehicle is towing a trailer, etc.
 The ICC system is designed to automatic ally check the sensor's operation within the limitation of the system.
When the sensor is covered with dirt or is obstruct ed, the system will automatically be canceled. If the sen-
sor 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 main-
tain the selected following distance from the vehicle ahead. Be sure to check and clean the sensor regularly.

Precautions for Lane Departure Wa
rning/Lane Departure PreventionINFOID:0000000006223714
LANE CAMERA UNIT HANDLING
To keep the proper operation of the LDW/LDP systems and prevent a system malfunction, be sure to observe
the following:
 Always keep the windshield clean.
 Do not attach a sticker (including transparent materi al) or install an accessory near the lane camera unit.
 Do not place reflective materials, such as white paper or a mirror, on the instrument panel. The reflection of
sunlight may adversely affect the lane camera unit capability of detecting the lane markers.
 Do not strike or damage the areas around the lane camera unit.
 Do not touch the camera lens.
 Do not remove the screw located on the lane camera unit.
LANE DEPARTURE WARNING (LDW)
 LDW system is only a warning device to inform the dr iver of a potential unintended lane departure. It will not
steer the vehicle or prevent loss of cont rol. It is the driver’s responsibility to stay alert, drive safely, keep the
vehicle in the traveling lane, and be in control of the vehicle at all times.
 LDW system will not operate at speeds below approximat ely 70 km/h (45 MPH) or if it cannot detect lane
markers.
 Excessive noise will interfere with the warning chime sound, and the chime may not be heard.
 LDW system may not function properly under the following conditions:
- On roads where there are multiple parallel lane marker s; lane markers that are faded or not painted clearly;
yellow painted lane markers; non-standard lane markers; or lane markers covered with water, dirt or snow,
etc.
- On roads where the discontinued lane markers are still detectable.
- On roads where there are sharp curves.
- On roads where there are sharply c ontrasting objects, such as shadows, snow, water, wheel ruts, seams or
lines remaining after road repairs. (The LDW syst em could detect these items as lane markers.)
- On roads where the traveling lane merges or separates.
- When the vehicle's traveling direction does not align with the lane marker.
- When traveling close to other vehicle in front of the vehicle, which obstructs the lane camera unit detection
range.
- When rain, snow or dirt adheres to the wi ndshield in front of the lane camera unit.
- When the headlights are not bright due to dirt on the lens or if the aiming is not adjusted properly.
- When strong light enters the lane camera uni t. (For example, the light directly shines on the front of the vehi-
cle at sunrise or sunset.)
- When a sudden change in brightness occurs. (For exampl e, when the vehicle enters or exits a tunnel or
under a bridge.)
LANE DEPARTURE PREVENTION (LDP)
 LDP system will not steer the vehicle or prevent loss of control. It is the driver’s responsibility to stay alert,
drive safely, keep the vehicle in the traveling lane, and be in control of vehicle at all times.
 LDP system is primarily intended for use on well-dev eloped freeways or highways. It may not detect the lane
markers in certain roads, weather or driving conditions.
 Using the LDP system under some conditions of road, lane marker or weather, or when driver change lanes
without using the turn signal could lead to an unexpect ed system operation. In such conditions, driver needs
to correct the vehicle's direction with dr iver's steering operation to avoid accidents.
 When the LDP system is operating, avoid excessive or sudden steering maneuvers. Otherwise, driver could
lose control of the vehicle.
 The LDP system will not operate at speeds below approxim ately 70 km/h (45 MPH) or if it cannot detect lane
markers.
 The LDP system may not function properly under the following conditions, and do not use the LDP system:
- During bad weather (rain, fog, snow, wind, etc.).
- When driving on slippery roads, such as on ice or snow, etc.
- When driving off-road such as on sand or rock, etc.
- When driving on winding or uneven roads.
- When there is a lane closure due to road repairs.
- When driving in a makeshift lane.
- When driving on roads where the lane width is too narrow.
