SYSTEM MAINTENANCE
The TSR system uses the same multi-
sensing front camera unit that is used by
the Lane Departure Warning (LDW) system,
located in front of the interior rearview mir-
ror. For additional information, refer to ”Sys-
tem maintenance” in the “Lane Departure
Warning (LDW)” section.

HOW TO ENABLE/DISABLE THE
LDW SYSTEM
Perform the following steps to enable or
disable the LDW system.1. Press the

∙ Do not use the LDW system under thefollowing conditions as it may not
function properly:
– During bad weather (rain, fog, snow, etc.).
– When driving on slippery roads, such as on ice or snow.
– When driving on winding or un- even roads.
– When there is a lane closure due to road repairs.
– When driving in a makeshif t or temporary lane.
– When driving on roads where the lane width is too narrow.
– When driving without normal tire conditions (for example, tire wear,
low tire pressure, installation of
spare tire, tire chains, nonstandard
wheels).
– When the vehicle is equipped with non-original brake parts or sus-
pension parts.
– When you are towing a trailer or other vehicle. ∙ The system may not function prop-
erly under the following conditions:
– On roads where there are multiple parallel lane markers; lane mark-
ers that are faded or not painted
clearly; yellow painted lane mark-
ers; non-standard lane markers; or
lane markers covered with water,
dirt, snow, etc.
– On roads where the discontinued lane markers are still detectable.
– On roads where there are sharp curves.
– On roads where there are sharply contrasting objects, such as shad-
ows, snow, water, wheel ruts,
seams or lines remaining af ter
road repairs. (The LDW system
could detect these items as lane
markers.)
– On roads where the traveling lane merges or separates.
– When the vehicle’s traveling direc- tion does not align with the lane
marker. – When traveling close to the vehicle
in front of you, which obstructs the
lane camera unit detection range.
– When rain, snow, dirt or an object adheres to the windshield in front
of the lane camera unit.
– When the headlights are not bright due to dirt on the lens or if the aim-
ing is not adjusted properly.
– When strong light enters the lane camera unit. (For example, the light
directly shines on the front of the
vehicle at sunrise or sunset.)
– When a sudden change in bright- ness occurs. (For example, when
the vehicle enters or exits a tunnel
or under a bridge.)
SYSTEM TEMPORARILY

∙ Do not place reflective materials, suchas white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit’s
capability of detecting the lane mark-
ers.
∙ Do not strike or damage the areas around the camera unit. Do not touch
the camera lens or remove the screw
located on the camera unit. If the cam-
era unit is damaged due to an accident,
it is recommended that you visit a
NISSAN dealer.
