uuWhen Driving uBSI (Blind Spot Information)*
Driving
Press the BSI OFF button until you hear a beep to turn on and off the system. A
message on the multi-information display appears for five seconds and indicates
that the system is on or off.
When BSI is off, the BSI indicator in the in strument panel stays on.
BSI stays off next time you sta rt the engine, if you turned it off the last time you drive
the vehicle.
■BSI On and Off1 BSI (Blind Spot Information)*
The BSI alert indicator may not come on under
following conditions:
•A vehicle does not stay in the alert zone for more
than two seconds.
•A vehicle is parked in a side lane.•The speed difference between your vehicle and the
vehicle you are passing is greater than 6 mph (10 km/h).
•An object not detected by the radar sensors
approaches or passes your vehicle.
Turn the system off when towing a trailer. The system
does not work properly for the following reasons:
•The added mass tilts the vehicle and changes the radar coverage.•The trailer itself can be detected by the radar sensors,
causing the BSI alert indicators to come on.
BSI may be adversel y affected when:•Objects (guard rails, poles, trees, etc,.) are detected.•An object that does not reflect radio waves well,
such as a motorcycle, is in the alert zone.
•Driving on a curved road.•A vehicle is moving from a far lane to the adjacent lane.•The system picks up external electrical interference.•The rear bumper or the sensors have been improperly
repaired or the rear bumper has been deformed.
•The orientation of the sensors has been changed.•In bad weather (Heavy rain, snow, and fog).
For a proper BSI use:
•Always keep the rear bu mper corner area clean.•Do not cover the rear bumper corner area with
labels or stickers of any kind.
•Take your vehicle to a dealer if you need the rear bumper
corner area or the radar sensors to be repaired, or the
rear bumper corner area is strongly impacted.

*2: If you drive in dusty conditions, replace the air cleaner element every 15,000 miles (24,000 km).
*3: If you drive primarily in urban areas that have high concentrations of soot in the air from industry and
from diesel-powered vehicles, replace the dust and pollen filter every 15,000 miles (24,000 km).

20 °F, -29 °C), or tow a trailer, replace every 60,000 miles/100,000 km.

mechanical (shear) stress to fluid. This requires differential fluid changes more frequently than
recommended by the Maintenance Minder. If you regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles/12,000 km, then every 15,000 miles/24,000 km.

NOTICEThe headlight aim is set by the factory, and does not
need to be adjusted. However, if you regularly carry
heavy items in the cargo ar ea or tow a trailer, have
the aiming readjusted at a dealer or by a qualified
technician.
The exterior lights’ inside lenses (headlights, brake
lamps, etc.) may fog temporarily after a vehicle wash
or while driving in the rain. This does not impact the
exterior light function.
