NOTE
In the following cases, the Forward Sensing Camera (FSC) cannot detect target objects
correctly, and each system may be unable to operate normally.
The height of the vehicle ahead is low. You drive your vehicle at the same speed as the vehicle ahead. Headlights are not turned on during the night or when going through a tunnel.
In the following cases, the Forward Sensing Camera (FSC) may not be able to detect
target objects correctly.
Under bad weather condition, such as rain, fog and snow. The window washer is being used or the windshield wipers are not used when it's raining. Ice, fog, snow, frost, rainfall, dirt, or foreign matter such as a plastic bag is stuck on
the windshield.
Trucks with low loading platforms and vehicles with an extremely low or high profile. When driving next to walls with no patterning (including fences and lon\
gitudinally
striped walls).
The taillights of the vehicle ahead are turned off. A vehicle is outside the illumination range of the headlights. The vehicle is making a sharp turn, or ascending or descending a steep s\
lope. Entering or exiting a tunnel. Heavy luggage is loaded causing the vehicle to tilt. Strong light is shone at the front of the vehicle (back light or high-beam light from on-
coming vehicles).
There are many light emitters on the vehicle ahead. When the vehicle ahead is not equipped with taillights or the taillights\
are turned off at
nighttime.
Elongated luggage or cargo is loaded onto installed roof rails and covers the Forward
Sensing Camera (FSC).
Exhaust gas from the vehicle in front, sand, snow, and water vapor rising from
manholes and grating, and water splashed into the air.
When towing a malfunctioning vehicle. The vehicle is driven with tires having significantly different wear. The vehicle is driven on down slopes or bumpy roads. There are water puddles on the road. The surroundings are dark such as during the night, early evening, or early morning,
or in a tunnel or indoor parking lot.
The illumination brightness of the headlights is reduced or the headlight illumination
is weakened due to dirt or a deviated optical axis.
The target object enters the blind spot of the Forward Sensing Camera (FSC). A person or object bursts onto the road from the shoulder or cuts right in front of you. You change lanes and approach a vehicle ahead. When driving extremely close to the target object. Tire chains or a temporary spare tire is installed. The vehicle ahead has a special shape. For example, a vehicle towing a t\
railer house
or a boat, or a vehicle carrier carrying a vehicle with its front pointed rearward.

When Driving
i-ACTIVSENSE
NOTE
Under the following conditions, the radar sensor (front) may not be able to detect
vehicles ahead or obstructions correctly and each system may not operate normally.
The rear surface of a vehicle ahead does not reflect radio waves effectively, such as
an unloaded trailer or an automobile with a loading platform covered by a soft top,
vehicles with a hard plastic tailgate, and round-shaped vehicles.
Vehicles ahead with low vehicle height and thus less area for reflecting radio waves. Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its
tires and onto your windshield.
The trunk compartment is loaded with heavy objects or the rear passenger seats are
occupied.
Ice, snow, or soiling is on the front surface of the front emblem. During inclement weather such as rain, snow, or sand storms. When driving near facilities or objects emitting strong radio waves.
Under the following conditions, the radar sensor (front) may not be able to detect
vehicles ahead or obstructions.
The beginning and end of a curve. Roads with continuous curves. Narrow lane roads due to road construction or lane closures. The vehicle ahead enters the radar sensor's blind spot. The vehicle ahead is running abnormally due to accident or vehicle damag\
e. Roads with repeated up and down slopes Driving on poor roads or unpaved roads. The distance between your vehicle and the vehicle ahead is extremely short. A vehicle suddenly comes close such as by cutting into the lane.
To prevent incorrect operation of the system, use tires of the same specified size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use tires
with significantly different wear patterns or tire pressures on the same vehicle (Including
the temporary spare tire).
If the battery power is weak, the system may not operate correctly. When driving on roads with little traffic and few vehicles ahead or obstructions for
the radar sensor (front) to detect, “Front Radar Sensor Blocked” may be temporarily
displayed, however, this does not indicate a problem.

Tire Pressure Monitoring System
Tire Pressure Monitoring System
The Tire Pressure Monitoring System (TPMS) monitors the air pressure of all\
four tires. If
the air pressure of one or more tires is too low, the system warns the driver by indicating the
tire pressure monitoring system warning light in the instrument cluster \
and operating a beep
sound. The system monitors the tire pressures indirectly using the data sent from the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the specified
tire pressure (value on the tire pressure label). Follow the procedure\
and perform the
initialization.
Refer to Tire Pressure Monitoring System Initialization on page 4-162.
The warning light flashes when the system has a malfunction.
Refer to Warning Indication/Warning Lights on page 4-33.

When Driving
Tire Pressure Monitoring System
CAUTION
Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire inflation pressure label, you should determine
the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires
is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and inflate them to the proper
pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may
affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the
driver's responsibility to maintain correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when
the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for approximately one minute and then
remain continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the installation of replacement
or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to
continue to function properly.
To avoid false readings, the system samples for a little while before indicating a problem. As
a result it will not instantaneously register a rapid tire deflation or blow out.

When Driving
Tire Pressure Monitoring System
NOTE
Because this system detects slight changes in tire conditions, the timing of the warning may
be faster or slower in the following cases:
The size, manufacturer, or the type of tires is different from the specification. The size, manufacturer, or the type of a tire is different from the others, or the level of tire
wear is excessively different between them.
A run-flat tire, studless tire, snow tire, or tire chains are used. An emergency tire is used (The tire pressure monitoring system warning light may flash
and then continue illuminating).
A tire is repaired using the emergency flat tire repair kit. The tire pressure is excessively higher than the specified pressure, or the tire pressure is
suddenly lowered for some reason such as a tire burst during driving.
The vehicle speed is lower than about 15 km/h (9.3 mph) (including wh\
en the vehicle is
stopped), or the drive period is shorter than 5 minutes.
The vehicle is driven on an extremely rough road or a slippery, icy road. Hard steering and rapid acceleration/deceleration are repeated such as during aggressive
driving on a winding road.
Load on the vehicle is applied to a tire such as by loading heavy luggage to one side of
the vehicle.
System initialization has not been implemented with the specified tire pressure.
