TPMS with Easy-Fill Tire Alert
When adding air to an under-inflated tire,
the TPMS with Easy-Fill Tire Alert provides
visual and audible signals outside the ve-
hicle to help you inflate the tires to the rec-
ommended COLD tire pressure.
Vehicle set-up
1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place theshif t lever in the P (Park) position.
3. Place the ignition switch in the ON posi- tion. Do not start the engine.
Operation
1. Add air to the tire.
2. Af ter a few seconds, the hazard indica- tors will start flashing.
3. When the designated pressure is reached, the horn beeps once and the
hazard indicators stop flashing.
4. Perform the above steps for each tire. • If the tire is over-inflated more thanapproximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash
three times. To correct the pressure,
push the core of the valve stem on the
tire briefly to release pressure. When the pressure reaches the designated
pressure, the horn beeps once.
• If the hazard indicator does not flash within approximately 15 seconds af ter
starting to inflate the tire, it indicates
that the Easy-Fill Tire Alert is not
operating.
• The TPMS will not activate the Easy-Fill Tire Alert under the following
conditions:– If there is interference from an exter- nal device or transmitter.
– The air pressure from the inflation device is not sufficient to inflate the
tire.
– There is a malfunction in the TPMS.
– There is a malfunction in the horn or hazard indicators.
– The identification code of the tire pressure sensor is not registered to
the system.
– The battery of the tire pressure sen- sor is low.
• If the Easy-Fill Tire Alert does not oper- ate due to TPMS interference, move
the vehicle about 3 f t (1 m) backward
or forward and try again.
If the Easy-Fill Tire Alert is not working, use a
tire pressure gauge.
5-8Starting and driving

If the radar sensorO1detects a slower
moving vehicle ahead, the system will re-
duce 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 ap-
proximately 40% of vehicle braking power)
if necessary.
The detection range of the sensor is ap-
proximately 650 f t (200 m) ahead.
VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE OPERATION
LSD4551
5-74Starting and driving

NOTE:
The approach warning chime may sound
and the system display may blink when
the ICC sensor detects objects on the
side of the vehicle or on the side of the
road. This may cause the ICC system to
decelerate or accelerate the vehicle. The
ICC sensor may detect these objects
when the vehicle is driven on winding
roads, narrow roads, hilly roads, or when
entering or exiting a curve. In these
cases you will have to manually control
the proper distance ahead of your
vehicle.
Also, the sensor sensitivity can be affected
by vehicle operation (steering maneuver or
driving position in the lane) or traffic or ve-
hicle condition (for example, if a vehicle is
being driven with some damage).
Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically can-
celed:
• When the vehicle ahead is not detectedand your vehicle is traveling below the
speed of 15 mph (25 km/h)
• When the system judges the vehicle is at a standstill • When the shif t lever is not in the D (Drive)
position, Manual mode or L (Low) range.
• When the parking brake system is applied
• When the VDC system is turned off
• When VDC operates
• When distance measurement becomes impaired due to adhesion of dirt or ob-
struction to the sensor
• When a wheel slips
• When the radar signal is temporarily interrupted
VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE LIMITATIONS
WARNING
Listed below are the system limitations
for the ICC system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
• The ICC system is primarily intended
for use on straight, dry, open roads
with light traffic. It is not advisable to
use the ICC system in city traffic or
congested areas. •
The ICC system will not adapt auto-
matically to road conditions. 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.
• As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive
or absentminded driving, or over-
come poor visibility in rain, fog, or
other bad weather. Decelerate the
vehicle speed by depressing the
brake pedal, depending on the dis-
tance 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 decelerates to a standstill
within the limitations of the system.
The system will cancel once it judges
that the vehicle has come to a stand-
still and sound a warning chime. To
prevent the vehicle from moving, the
driver must depress the brake pedal.
5-82Starting and driving

•Always pay attention to the opera-
tion of the vehicle and be ready to
manually control the proper follow-
ing distance. The ICC system may not
be able to maintain the selected dis-
tance between vehicles (following
distance) or selected vehicle speed
under some circumstances.
• The system may not detect the ve-
hicle in front of you in certain road or
weather conditions. To avoid acci-
dents, never use the ICC system un-
der 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.
– During bad weather (rain, fog,
snow, etc.)
– When rain, snow or dirt adhere to
the bumper around the distance
sensor
– On steep downhill roads (the ve-
hicle may go beyond the set ve-
hicle 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 fre-
quent acceleration or
deceleration
– Interference by other radar
sources
• Do not use the ICC system 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. Al-
ways stay alert and avoid using the
ICC system where not recommended
in this warning section.
The radar 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 The sensor generally detects the signals
returned from the vehicle ahead. Therefore,
if the sensor cannot detect the reflection
from the vehicle ahead, the ICC system
may not maintain the selected distance.
The following are some conditions in which
the sensor cannot properly detect a ve-
hicle ahead and the system may not oper-
ate properly:
• When snow or road spray from traveling
vehicles reduces the sensor’s detection.
• When your vehicle is towing a trailer, etc.
• When excessively heavy baggage is loaded in the rear seat or cargo area of
your vehicle.
The ICC system is designed to automati-
cally check the sensor’s operation within
the limitations of the system.
When the sensor is covered with dirt or is
obstructed, the system will automatically
be canceled. If the sensor 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 maintain the selected
following distance from the vehicle ahead.
Be sure to check and clean the sensor
regularly.
