BLIND SPOT INFORMATION

SYSTEM

WARNING

Blind Spot Information System as a

replacement for using the interior

and exterior mirrors or looking over your

shoulder before changing lanes. The Blind

The Blind Spot Information System is

designed to aid you in detecting vehicles

that may have entered the blind spot zone

(A). The detection area is on both sides of

your vehicle, extending rearward from the

exterior mirrors to approximately 13 ft

(4 m) beyond the bumper. The system is

designed to alert you if certain vehicles

enter the blind spot zone while driving.

System Lights and Messages

E205199

The system uses radar sensors that are

located behind the bumper fascia on each

side of your vehicle. Any dirt, mud and

snow in front of the sensors and/or driving

in heavy rain can cause system

degradation. Also, other types of

obstructions in front of the sensor can

cause system degradation. This is referred

to as a ‘blocked’ condition.

repair compound to these areas, this can

cause degraded system performance.

You can temporarily switch the Blind Spot

Information System off in the information

display. See General Information (page

91). When the Blind Spot Information

System switches off, you will not receive

alerts and the information display shows

a system off message. The telltale in the

cluster also illuminates. When you switch

the Blind Spot Information System on or

off, the alert indicators flash twice.

Note: The Blind Spot Information System

remembers the last selected on or off

setting.

You can also have the Blind Spot

Information System switched off

permanently at an authorized dealer. Once

switched off permanently, the system can

only be switched back on at an authorized

dealer.

If the system detects a degraded

performance condition, a message warning

of a blocked sensor will appear in the

information display. Also the BLIS alert

indicators will remain ON and BLIS will no

longer provide any vehicle warnings. You

can clear the information display warning

but the alert indicators will remain

illuminated.

A "blocked" condition can be cleared in

two ways:

•

After the blockage in front of the

sensors is removed or the

rainfall/snowfall rate decreases or

stops, drive for a few minutes in traffic

to allow the sensors to detect passing

vehicles.

•

By cycling the ignition from ON to OFF

and then back ON.

CROSS TRAFFIC ALERT

factory equipped trailer tow module and it

is towing a trailer, the sensors will

Cross Traffic Alert is designed to warn you

of vehicles approaching from the sides

the information display. See Information

Cross Traffic Alert turns on when you start

the engine and you shift into reverse (R).
