2018 INFINITI QX30 Radar sensors

Message Possible causes/consequences and solutions
[Radar Sensor (See
Operator's Manual):]At least one of the following driving systems or driving safety systems is temporarily restricted or inoperative:
•Forward Emergency Braking•Intelligent Cruise Control•Blind Spot Warning
Possible causes:
•The sensors in the radiator trim and/or at the sides of the rear bumpers are dirty.•The function of the driving system and/or driving safety system is impaired due to heavy rain or snow.
A warning tone also sounds.
Once the causes listed above no longer apply, the display message goes out. All driving systems/driving safety systems are
operative again.
If the display message does not disappear:
1. Pull over and stop the vehicle safely as soon as possible, paying attention to road and traffic conditions
2. Secure the vehicle against rolling away.
3. Switch off the engine.
4. Clean the sensors in the following locations:
- In the radiator trim
- At the sides of the rear bumper
5. Restart the engine. The display message disappears.
[SRS Malfunction Service
Required]The restraint system needs servicing. The
warning light also lights up in the combination meter.
It is recommended you visit an INFINITI retailer for these services.
Unless checked and repaired, the Supplemental Restraint Systems and/or the pretensioner seat belt may not function properly.
WARNING
If this light is on, it could mean that the front air bag, side air bag, curtain air bag systems and/or pretensioner systems will not
operate in an accident. To help avoid injury to yourself or others, have your vehicle checked as soon as possible. It is recommended
you visit an INFINITI retailer for this service.
For further information about the restraint system, see "Supplemental Restraint System (SRS)".
2-38Instruments and controls

The BSW system uses radar sensorsAin-
stalled near the rear bumper to detect other
vehicles beside your vehicle in an adjacent
lane.The radar sensors can detect vehicles on ei-
ther side of your vehicle within the detection
zone shown as illustrated. This detection
zone starts from the outside mirror of your
vehicle and extends approximately 10 ft (3 m)
behind the rear bumper, and approximately
10 ft (3 m) sideways.

BSW SYSTEM OPERATION
1Side indicator light
2Steering wheel mounted controls
3Vehicle information display
AMENU bar
The BSW system operates above approxi-
mately 20 MPH (30 km/h). When the BSW is
activated, the side indicator light illuminates
in yellow up to a speed of 20 MPH (30 km/h).
At speeds above 20 MPH (30 km/h), the indi-
cator light goes out and the BSW system is
operational.
Illustration 1:If the radar sensors detect a
vehicle in the detection zone, the BSW indi-
cator light
1located by the outside mirrors
illuminates.

Illustration 2:If the turn signal is then acti-
vated, the system chimes (twice) and the
BSW indicator light flashes. The BSW indica-
tor light continues to flash until the detected
vehicles leave the detection zone.
NOTE
•The BSW indicator lights illuminate for a
few seconds when the ignition switch is
placed in the ON position.
•The brightness of the BSW indicator lights
is adjusted automatically depending on the
brightness of the ambient light.
•If a vehicle comes into the detection zone
after the driver activates the turn signal,
then only the BSW indicator light flashes
and no chime sounds. (See "Another ve-
hicle approaching from behind" later in this
section.)
A chime sounds if the radar sensors have
already detected vehicles when the driver ac-
tivates the turn signal.
WARNING
•Do not use the BSW system when tow-
ing a trailer because the system may not
function properly.
•Excessive noise (for example audio sys-
tem volume, open vehicle window) will
interfere with the chime sound, and it
may not be heard.
•The radar sensors may not be able to
detect and activate BSW when certain
objects are present such as:
–Pedestrians, bicycles, animals
–Several types of vehicles such as mo-
torcycles
–Oncoming vehicles
–Vehicles remaining in the detection
zone when you accelerate from a
stop.–A vehicle merging into an adjacent
lane at a speed approximately the
same as your vehicle.
–A vehicle approaching rapidly from
behind.
–A vehicle which your vehicle over-
takes rapidly.
•Severe weather or road spray conditions
may reduce the ability of the radar to
detect other vehicles.
•The radar sensors detection zone is de-
signed based on a standard lane width.
When driving in a wider lane, the radar
sensors may not detect vehicles in an
adjacent lane. When driving in a narrow
lane, the radar sensors may detect ve-
hicles driving two lanes away.
•The radar sensors are designed to ignore
most stationary objects, however ob-
jects such as guardrails, walls, foliage
and parked vehicles may occasionally be
detected. This is a normal operating
condition.

BSW SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the BSW system. Failure to operate the
vehicle in accordance with these system
limitations could result in serious injury or
death.
•The BSW system cannot detect all ve-
hicles under all conditions.
•The radar sensors may not be able to
detect and activate BSW when certain
objects are present such as:
–Pedestrians, bicycles, or animals.

5-40Starting and driving

–Vehicles such as motorcycles, low
height vehicles, or high ground clear-
ance vehicles.
–Oncoming vehicles.
–Vehicles remaining in the detection
zone when you accelerate from a
stop.
–A vehicle merging into an adjacent
lane at a speed approximately the
same as your vehicle.
–A vehicle that is too close to your
vehicle.
–A vehicle approaching rapidly from
behind.
–A vehicle which your vehicle over-
takes rapidly.
•The radar sensors detection zone is de-
signed based on a standard lane width.
When driving in a wider lane, the radar
sensors may not detect vehicles in an
adjacent lane. When driving in a narrow
lane, the radar sensors may detect ve-
hicles driving two lanes away.
•The radar sensors are designed to ignore
most stationary objects, however ob-
jects such as guardrails, walls, foliage
and parked vehicles may occasionally be
detected. This is a normal operating
condition.
•The following conditions may reduce the
ability of the radar to detect other ve-
hicles:
–Severe weather
–Road spray
–Ice/frost/dirt build-up on the vehicle
•Do not attach stickers (including trans-
parent material), install accessories or
apply additional paint near the radar
sensors. These conditions may reduce
the ability of the radar to detect other
vehicles.
•Do not use the BSW system when tow-
ing a trailer because the system may not
function properly.
•Excessive noise (e.g. audio system vol-
ume, open vehicle window) will interfere
with the chime sound, and it may not be
heard.
•The BSW system may not provide a
warning for vehicles that pass through
the detection zone quickly.
Another vehicle approaching from
behind
Illustration 1: The BSW indicator light illumi-
nates if a vehicle enters the detection zone
from behind in an adjacent lane.
However, if the overtaking vehicle is travel-
ling much faster than your vehicle, the indica-
tor light may not illuminate before the de-
tected vehicle is beside your vehicle. Always
use the side and rear mirrors and turn and
look in the direction your vehicle will move to
ensure it is safe to change lanes.

Illustration 2: If the driver activates the turn
signal, then the system chimes (twice) and the
BSW indicator light flashes.
NOTE
•The radar sensors may not detect vehicles
which are approaching rapidly from be-
hind.
•If the driver activates the turn signal be-
fore a vehicle enters the detection zone,
the BSW indicator light will flash but no
chime will sound when the other vehicle is
detected.
Accelerate from a stop
NOTE
Illustration 3: If you accelerate from a stop
with a vehicle in the detection zone, the
other vehicle may not be detected.
Overtaking another vehicle
When you overtake a vehicle, the warning
only occurs if the difference in speed is less
than 7 MPH (12 km/h).
Illustration 4: The side indicator light illumi-
nates if you overtake a vehicle and that ve-
hicle stays in the detection zone for approxi-
mately 3 seconds.

NOTE
•When overtaking several vehicles in a row,
the vehicles after the first vehicle may not
be detected if they are travelling close to-
gether.
•The radar sensors may not detect slower
moving vehicles if they are passed quickly.
•If the driver activates the turn signal be-
fore a vehicle enters the detection zone,
the side indicator light will flash but no
chime will sound when the other vehicle is
detected.
