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
Previous feature activation happened within the last one second
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)
Lane width too narrow or too wide
Camera not calibrated after a windshield replacement
When driving on tight roads or on uneven roads
Why does the vehicle not come back into the middle of the lane
always, 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

How Your Vehicle Differs from Other Vehicles
Crossover vehicles can differ from
some other vehicles in a few
noticeable ways. Your vehicle may
be:
•Higher – to allow higher load
carrying capacity.
•Shorter – to give it the capability
to approach inclines. All other
things held equal, a shorter
wheelbase may make your vehicle
quicker to respond to steering
inputs than a vehicle with a
longer wheelbase.
•Narrower – to provide greater
maneuverability in tight spaces.
As a result of the above dimensional differences, crossover vehicles often
will have a higher center of gravity and a greater difference in center of
gravity between the loaded and unloaded condition.
These differences that make your vehicle so versatile also make it handle
differently than an ordinary passenger car.
TIRE CARE
Information About Uniform Tire Quality Grading
Tire Quality Grades apply to new
pneumatic passenger car tires. The Tire
Quality Grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
•Treadwear 200 Traction AA Temperature A
These Tire Quality Grades are determined by standards that the United
States Department of Transportation has set.
Tire Quality Grades apply to new pneumatic passenger car tires. They do
not apply to deep tread, winter-type snow tires, space-saver or
temporary use spare tires, light truck or LT type tires, tires with nominal

INFORMATION CONTAINED ON THE TIRE SIDEWALL
Both U.S. and Canada Federal regulations require tire manufacturers to
place standardized information on the sidewall of all tires. This
information identifies and describes the fundamental characteristics of
the tire and also provides a U.S. DOT Tire Identification Number for
safety standard certification and in case of a recall.
Information on P Type Tires
P215/65R15 95H is an example of a
tire size, load index and speed
rating. The definitions of these
items are listed below. (Note that
the tire size, load index and speed
rating for your vehicle may be
different from this example.)
A.P:
Indicates a tire, designated by the Tire and Rim Association, that may
be used for service on cars, sport utility vehicles, minivans and light trucks.
Note:If your tire size does not begin with a letter, this may mean it is
designated by either the European Tire and Rim Technical Organization
or the Japan Tire Manufacturing Association.
B.215:
Indicates the nominal width of the tire in millimeters from sidewall
edge to sidewall edge. In general, the larger the number, the wider the tire.
C.65:Indicates the aspect ratio which gives the tire’s ratio of height to
width.
D.R:Indicates a radial type tire.
E.15:Indicates the wheel or rim diameter in inches. If you change your
wheel size, you will have to purchase new tires to match the new wheel
diameter.
F.95:Indicates the tire’s load index. It is an index that relates to how
much weight a tire can carry. You may find this information in your
owner’s manual. If not, contact a local tire dealer.

Information on T Type Tires
T type tires have some additional
information beyond those of P type
tires. These differences are
described below.
T145/80D16 is an example of a tire
size.
Note:The temporary tire size for
your vehicle may be different from
this example. Tire Quality Grades
do not apply to this type of tire.
A.T:Indicates a type of tire, designated by the Tire and Rim
Association, that is intended for temporary service on cars, sport-utility
vehicles, minivans and light trucks.
B.145:Indicates the nominal width of the tire in millimeters from
sidewall edge to sidewall edge. In general, the larger the number, the
wider the tire.
C.80:Indicates the aspect ratio, which gives the tire’s ratio of height to
width. Numbers of 70 or lower indicate a short sidewall.
D.D:Indicates a diagonal type tire.R:Indicates a radial type tire.
E.16:Indicates the wheel or rim diameter in inches. If you change your
wheel size, you will have to purchase new tires to match the new wheel
diameter.
Location of the Tire Label
You will find a Tire Label containing tire inflation pressure by tire size
and other important information located on the B-Pillar or the edge of
the driver’s door. See the payload description and graphic in theLoad
Carryingchapter.
