The system uses radar sensors for the
following features.NOTEThe BSD/RCTA radar sensor has been
certified by the radio wave related laws
of the U.S. and other FCC compliant
countries, Canada and Mexico. When
driving in other countries, certifica-
tion of the country where the vehicle is
driven must be obtained. For certifica-
tion in the U.S. and other FCC compli-
ant countries, Canada and Mexico,
refer to "Certification for the BSD/
RCTA" 
P275.

Blind Spot Detection (BSD)1) Operating range
The system notifies the driver of the pres-
ence of vehicles in its blind spot.
 If the system detects a vehicle in its
blind spot, it warns the driver by illumi-
nating the BSD/RCTA approach indicator
light(s) on the outside mirror(s).
 If the driver operates the turn signal
lever in the direction where the BSD/
RCTA approach indicator light is illumi-
nating, the system warns the driver of
dangers by flashing the BSD/RCTA
approach indicator light.
▽Lane Change Assist (LCA)1) Operating rangeThe system notifies the driver of vehicles
approaching at a high speed in the neigh-
boring lanes. 
If the system detects a vehicle
approaching at a high speed in the neigh-
boring lanes, it warns the driver of
dangers by illuminating the BSD/RCTA
approach indicator light(s) on the outside
mirror(s).
 If the driver operates the turn signal
lever in the direction where the BSD/
RCTA approach indicator light is illumi-
nating, the system warns the driver of
dangers by flashing the BSD/RCTA
approach indicator light.

Rear Cross Traffic Alert (RCTA)1) Operating rangeThe system notifies the driver of another
vehicle approaching from either side when
driving in reverse. This feature helps the

Reverse Automatic Braking (RAB) System (If Equipped)
281
Starting and Operating7
– CONTINUED –
- Pedestrians.
- Moving objects including
moving vehicles.
- Objects which absorbs sound
waves such as cloth or snow.
- Objects whose surface has a
diagonal angle.
- Objects that are low to the
ground such as parking blocks.
- Objects that are high above the
ground such as objects hanging
from above.
- Objects that are out of range of
the center of the vehicle in the hori-
zontal direction.
- Objects that are not in a vertical
direction.
 When reversing the vehicle, the
functions may not be able to work
properly or may cause a system
malfunction if the following conditions
exist.
High frequency sound from other
sources are nearby:
- Horn sound from another
vehicle.
- Engine sound from other vehi-
cles.
- Sound of an air brake.
- Vehicle detection equipment or a
sonar from another vehicle. - A sound wave with a frequency
similar to the vehicle’s system is
transmitted near by.
- A vehicle equipped with the
same system is reversing toward
your reversing direction.
Weather conditions:
- Extremely high or extremely low
temperatures in which the area near
the sonar sensor becomes too hot
or too cold to operate.
- The sonar sensors or the rear
bumper near the sonar sensors are
exposed to heavy rain or a signifi-
cant amount of water.
- Fog, snow or sandstorm, etc.
- Air is moving rapidly such as
when a strong wind is blowing.
Parts attached to the rear bumper
near the sonar sensor:
- Commercial electr
onic parts (fog
light, fender pole, radio antenna) or
commercial attachment parts (trailer
hitch, bicycle carrier, bumper guard)
are attached.
- Parts that emit high frequency
sound, such as a horn or speaker,
are attached.
Vehicle conditions:
- Ice, snow or mud is adhered to
the sonar sensors or the rear
bumper near the sonar sensor. - The vehicle is significantly
inclined.
- The ground clearance is signifi-
cantly reduced due to the vehicle’s
loading condition, etc.
- When the sonar sensor is
misaligned due to a collision or an
accident.
Surrounding environment:
- A cloth banner, flag, hanging
branch or railroad crossing bars are
present in the reversing direction.
- When reversing on a gravel or
grassy area.
- When reversing in an area where
objects or walls are adjacent to the
vehicle such as narrow tunnels,
narrow bridges, narrow roads or
narrow garages.
- Wheel track or hole is present in
the ground of the reversing direc-
tion.
- When reversing over a drainage
cover (grating cover).

Access Key Fob – If Access Key Fob Does Not Operate Properly
325
In Case of Emergency9
– CONTINUED –
1. Release the parking brake and put the
transmission in neutral.
2. The ignition switch should be in the
“ON” position while the vehicle is being
towed.
3. Take up slack in the towline slowly to
prevent damage to the vehicle.
9-7. Access Key Fob – If
Access Key Fob Does Not Operate ProperlyThe following functions may be inoperable
because of strong radio signals in the
surrounding area or a low battery condi-
tion of the access key fob.
Locking/unlocking doors including
trunk
 Switching power status
 Starting engine
In such cases, perform the following
procedure. When the battery of the
access key fob is discharged, replace it
with a new one. Refer to "Replacing
Battery of Access Key Fob" P376.
CAUTION
 If transmission failure occurs,
transport your vehicle on a flat-
bed truck.Sometime damaged vehicles
cannot be towed because of their
damaged condition. In that case,
use a flat-bed truck for transpor-
tation.The traveling speed must be
limited to less than 20 mph (32
km/h) and the traveling distance
to less than 19 miles (30 km). For
greater speeds and distances,
transport your vehicle on a flat-
bed truck.Use a flat-bed truck if there are
long distance downgrades or
steep slopes. However, do not
apply the brake pedal for a long
time because the engine braking
will not work while towing. Doing
so could overheat the brake.Drive carefully and do not make
an impact on the towing rope by
suddenly starting.
Use a specific towing rope for
towing. If wire ropes and metal
chains are needed to be used for
towing, wrap the contact portion
of the bumper with cloth to
protect it from damage.
CAUTION
Keep metallic objects, magnetic
sources and signal transmitters
away from the area between the
access key fob and the push-button
ignition switch. They may interfere
with the communication between
the access key fob and the push-
button ignition switch.

Tire Information

Consumer Information and Reporting Safety Defects13
– CONTINUED –
The vehicle placard shows original
tire size, recommended cold tire
inflation pressure on each tire at
maximum loaded vehicle weight,
seating capacity and loading infor-
mation.
▼Adverse safety consequences
of under-inflation
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to flex severely and to
rapidly become hot. A sharp
increase in temperature could
cause tread separation, and failure
of the tire(s). Possible resulting loss
of vehicle control could lead to an
accident.
▼ Measuring and adjusting air
pressure to achieve proper
inflation
Check and, if necessary, adjust the
pressure of each tire (including the
spare) at least once a month and
before any long journey. Check the
tire pressures when the tires are
cold. Use a pressure gauge to adjust the tire pressures to the
specific values. Driving even a short
distance warms up the tires and
increases the tire pressures. Also,
the tire pressures are affected by
the outside temperature. It is best to
check tire pressure outdoors before
driving the vehicle. When a tire
becomes warm, t
he air inside it
expands, causing the tire pressure
to increase. Be careful not to
mistakenly release air from a warm
tire to reduce its pressure.
■ Glossary of Tire TerminologyAccessory weight
The combined weight (in excess of
those standard items which may be
replaced) of automatic transmis-
sion, power steering, power brakes,
power windows, power seats, radio,
and heater, to the extent that these
items are available as factory-
installed equipment (whether
installed or not).
 Bead
The part of the tire that is made of
steel wires, wrapped or reinforced by ply cords and that is shaped to fit
the rim.

Bead separation
A breakdown of the bond between
components in the bead.
 Bias ply tire
A pneumatic tire in which the ply
cords that extend to the beads are
laid at alternate an gles substantially
less than 90 degrees to the
centerline of the tread.
 Carcass
The tire structure, except tread and
sidewall rubber which, when
inflated, bears the load.
 Chunking
The breaking away of pieces of the
tread or sidewall.
 Cold tire pressure
The pressure in a tire that has been
driven less than 1 mile or has been
standing for three hours or more.
 Cord
The strands forming the plies in the
tire.
