center. If your vehicle continues drifting out
of the lane, the system provides a steering
wheel vibration.

System Display

E151660

When you switch on the system, an
overhead graphic of a vehicle with lane
markings will display in the information
display. If you select aid mode when you
switch on the system, a separate white
icon will also appear or in some vehicles
arrows will display with the lane markings.

When you switch off the system, the lane
marking graphics will not display.

While the system is on, the color of the
lane markings will change to indicate the
system status.

Gray: Indicates that the system is
temporarily unable to provide a warning
or intervention on the indicated side(s).
This may be because:

•

Your vehicle is under the activation
speed.

•

The turn indicator is active.

•

Your vehicle is in a dynamic maneuver.

•

The road has no or poor lane markings
in the camera field-of-view.

•

The camera is obscured or unable to
detect the lane markings due to
environmental conditions (significant
sun angles, shadows, snow, heavy rain
or fog), traffic conditions (following a
large vehicle that is blocking or
shadowing the lane), or vehicle
conditions (poor headlamp
illumination).

See Troubleshooting for additional
information.

Green: Indicates that the system is
available or ready to provide a warning or
intervention, on the indicated side(s).

Yellow: Indicates that the system is
providing or has just provided a lane
keeping aid intervention.

Red: Indicates that the system is providing
or has just provided a lane keeping alert
warning.

The system can be temporarily suppressed
at any time by the following:

•

Quick braking.

•

Fast acceleration.

•

Using the turn signal indicator.

•

Evasive steering maneuver.

Troubleshooting

Why is the feature not available (line markings are gray) when I can see the lane markings

on the road?

Vehicle speed is outside the operational range of the feature

Sun is shining directly into the camera lens

Quick intentional lane change

Staying too close to the lane marking

Driving at high speeds in curves

The last Alert warning or Aid intervention occurred a short time ago

Ambiguous lane markings (mainly in construction zones)

Rapid transition from light to dark or vice versa

Sudden offset in lane markings

ABS or AdvanceTrac activation

Camera blockage due to dirt, grime, fog, frost or water on the windshield

Driving too close to the vehicle in front of you

Transitioning between no lane markings to lane markings or vice versa

Standing water on the road

Faint lane markings (partial yellow lane markings on concrete roads)

Why is the feature not available (line markings are gray) when I can see the lane markings

on the road?

Lane width too narrow or too wide

Camera not calibrated after a windshield replacement

Driving on tight roads or on uneven roads

Why does the vehicle not come back toward the middle of the lane, as expected, in the

Aid or Aid + Alert mode?

High cross winds

Large road crown

Rough roads, grooves, shoulder drop-offs

Heavy uneven loading of the vehicle or improper tire inflation pressure

If the tires have been exchanged (including snow tires), or the suspension has been
modified

BLIND SPOT INFORMATION
SYSTEM

WARNING

To help avoid injuries, NEVER use the
Blind Spot Information System as a
replacement for using the interior

and exterior mirrors or looking over your
shoulder before changing lanes. The Blind
Spot Information System is not a
replacement for careful driving.

A

A

E124788

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.

Note: The Blind Spot Information System
does not prevent contact with other vehicles
or objects; nor detect parked vehicles,
people, animals or infrastructure (fences,
guardrails, trees). It’s only designed to alert
you to vehicles in the blind spot zones.

Note: When a vehicle passes quickly
through the blind spot zone, typically fewer
than two seconds, the system does not
trigger.

Using the System

The Blind Spot Information System turns
on when you start the engine and you drive
your vehicle forward above 5 mph
(8 km/h).

For automatic transmissions, the Blind
Spot Information System remains on while
the transmission is in drive (D). If shifted
into reverse (R) or park (P) the Blind Spot
Information System turns off. Once shifted
back into drive (D), the Blind Spot
Information System turns back on when
you drive your vehicle above 5 mph
(8 km/h).

For manual transmissions, the Blind Spot
Information System is on for all gears
except the reverse (R).

Note: The Blind Spot Information System
does not function in reverse (R) or park (P).

System Lights and Messages

E142442

The Blind Spot Information System
illuminates an amber alert indicator in the
outside mirror on the side of your vehicle
the approaching vehicle is coming from.
When the Blind Spot Information System
is alerting on a vehicle and the
corresponding turn signal is ON, the Blind
Spot Information System alert indicator
flashes as an increased warning level.

The alert indicator dims when the system
detects nighttime darkness.

Note: The alert indicator flashes in case of
an alert and the turn signal is set to that side
at the same time.

System Sensor Blockage

WARNING

To help avoid injuries, NEVER use the
Blind Spot Information System as a
replacement for using the interior

and exterior mirrors or looking over your
shoulder before changing lanes. The Blind
Spot Information System is not a
replacement for careful driving.

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.
