Heated Mirrors — If Equipped
These mirrors are heated to melt frost or ice. This
feature is activated whenever you turn on the rear
window defroster. Refer to “Rear Window Features” in
“Understanding The Features Of Your Vehicle” for fur-
ther information.
Tilt Mirrors In Reverse (Available With Memory
Seat Only) — If Equipped
Tilt Mirrors in Reverse provides automatic outside mirror
positioning which will aid the drivers view of the ground
rearward of the front doors. Outside mirrors will move
slightly downward from the present position when the
vehicle is shifted into REVERSE. Outside mirrors will
then return to the original position when the vehicle is
shifted out of REVERSE position. Each stored memory
setting will have an associated Tilt Mirrors in Reverse
position. NOTE:
The Tilt Mirrors in Reverse feature is not en-
abled when delivered from the factory. The Tilt Mirrors in
Reverse feature can be enabled or disabled in the Elec-
tronic Vehicle Information Center (EVIC). Refer to “Elec-
tronic Vehicle Information Center (EVIC)/Customer-

Sun Visor Extension — If Equipped
This feature has a pull out extension on the sun visor for
increased coverage.
BLIND SPOT MONITORING — IF EQUIPPED
The Blind Spot Monitoring (BSM) system uses two radar-
based sensors, located inside the rear bumper fascia, to
detect highway licensable vehicles (automobiles, trucks,
motorcycles, etc.) that enter the blind spot zones from the
rear/front/side of the vehicle.
Illuminated Vanity Mirror
Rear Detection Zones
112 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

When the vehicle is started, the BSM warning light will
momentarily illuminate in both outside rear view mirrors
to let the driver know that the system is operational. The
BSM system sensors operate when the vehicle is in any
forward gear or REVERSE and enters stand by mode
when the vehicle is in PARK.
The BSM detection zone covers approximately one lane
on both sides of the vehicle (11 ft or 3.35 m). The zone
starts at the outside rear view mirror and extends ap-
proximately 20 ft (6 m) to the rear of the vehicle. The BSM
system monitors the detection zones on both sides of the
vehicle when the vehicle speed has reached approxi-
mately 6 mph (10 km/h) or higher and will alert the
driver of vehicles in these areas.NOTE:
•The BSM system does NOT alert the driver about
rapidly approaching vehicles that are outside the
detection zones.
•The BSM system detection zone DOES NOT change if
your vehicle is towing a trailer. Therefore, visually
verify the adjacent lane is clear for both your vehicle
and trailer before making a lane change. If the trailer
or other object (i.e., bicycle, sports equipment) extends
beyond the side of your vehicle, this may result in the
BSM warning light remaining illuminated the entire
time the vehicle is in a forward gear.3
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 113

The area on the rear fascia where the radar sensors are
located must remain free of snow, ice, and dirt/road
contamination so that the BSM system can function
properly. Do not block the area of the rear fascia where
the radar sensors are located with foreign objects (bum-
per stickers, bicycle racks, etc.).The BSM system notifies the driver of objects in the
detection zones by illuminating the BSM warning light
located in the outside mirrors in addition to sounding an
audible (chime) alert and reducing the radio volume.
Refer to “Modes Of Operation” for further information.

Warning Light Location
114 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

The BSM system monitors the detection zone from three
different entry points (side, rear, front) while driving to
see if an alert is necessary. The BSM system will issue an
alert during these types of zone entries.
Entering From The Side
Vehicles that move into your adjacent lanes from either
side of the vehicle.
Side Monitoring

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 115

Entering From The Rear
Vehicles that come up from behind your vehicle on either
side and enter the rear detection zone with a relative
speed of less than 30 mph (48 km/h).Overtaking Traffic
If you pass another vehicle slowly (with a relative speed
less than 10 mph (16 km/h) and the vehicle remains in
the blind spot for approximately 1.5 seconds, the warning
light will be illuminated. If the difference in speed
between the two vehicles is greater than 10 mph
(16 km/h), the warning light will not illuminate.
Rear Monitoring
Overtaking/Approaching
116 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

The BSM system is designed not to issue an alert on
stationary objects such as guardrails, posts, walls, foliage,
berms, etc. However, occasionally the system may alert
on such objects. This is normal operation and your
vehicle does not require service.

The BSM system will not alert you of objects that are
traveling in the opposite direction of the vehicle in
adjacent lanes.WARNING!
The Blind Spot Monitoring system is only an aid to
help detect objects in the blind spot zones. The BSM
system is not designed to detect pedestrians, bicy-
clists, or animals. Even if your vehicle is equipped
with the BSM system, always check your vehicles
mirrors, glance over your shoulder, and use your turn
signal before changing lanes. Failure to do so can
result in serious injury or death.
Rear Cross Path
The Rear Cross Path (RCP) feature is intended to aid the
driver when backing out of parking spaces where their
vision of oncoming vehicles may be blocked. Proceed
slowly and cautiously out of the parking space until the
rear end of the vehicle is exposed. The RCP system will
then have a clear view of the cross traffic and if an
oncoming vehicle is detected, alert the driver.
