standard lane markers; lane
markers covered with water,
dirt, snow, etc.
— On roads where discontinued lane markers are still detect-
able.
— On roads where there are sharp curves.
— On roads where there are sharply contrasting objects,
such as shadows, snow,
water, wheel ruts, seams or
lines remaining after road re-
pairs.
— On roads where the traveling lane merges or separates.
— When the vehicle’s traveling direction does not align with
the lane markers.
— When traveling close to the vehicle in front of you, which
obstructs the lane camera
unit detection range.
— When rain, snow or dirt ad- heres to the windshield in
front of a lane camera unit.
— When the headlights are not bright due to dirt on the lens
or if aiming is not adjusted properly.
— When strong light enters a lane camera unit. (For exam-
ple: light directly shines on the
front of the vehicle at sunrise
or sunset.)
— When a sudden change in brightness occurs. (For exam-
ple: when the vehicle enters or
exits a tunnel or under a
bridge.)
. Do not use the I-BSI system under
the following conditions because
the system may not function
properly.
— During bad weather. (For ex-
ample: rain, fog, snow, etc.)
— When driving on slippery roads, such as on ice or snow,
etc.
— When driving on winding or uneven roads.
— When there is a lane closure due to road repairs.
— When driving in a makeshift or temporary lane.
— When driving on roads where the lane width is too narrow. — When driving with a tire that is
not within normal tire condi-
tions (for example, tire wear,
low tire pressure, installation
of spare tire, tire chains, non-
standard wheels).
— When the vehicle is equipped with non-original steering
parts or suspension parts.
— When towing a trailer or other vehicle.
. Excessive noise (for example,
audio system volume, open vehi-
cle window) will interfere with the
chime sound, and it may not be
heard.

.The radar sensors detect ap-
proaching (moving) vehicles. The
radar sensors cannot detect
every object such as:
— Pedestrians, bicycles, animals
or child operated toy vehicles
— A vehicle that passing at speeds greater than approxi-
mately 15 MPH (24 km/h)
. The radar sensors may not detect
approaching vehicles in certain
situations:
— Illustration a. When a vehicle
parked next to you obstructs
the beam of the radar sensor.
— Illustration b. When the vehicle is parked in an angled parking
space.
— Illustration c. When the vehicle is parked on inclined ground.
— Illustration d. When an ap- proaching vehicle turns into
your vehicle’s parking lot aisle.
— Illustration e. When the angle formed by your vehicle and
approaching vehicle is small.
. The following conditions may re-
duce the ability of the radar
sensors to detect other vehicles: — Severe weather
— Road spray
— Ice/frost/dirt build up on the
vehicle
. Do not attach stickers (including
transparent material), install ac-
cessories or apply additional
paint near the radar sensors.
These conditions may reduce the
ability of the radar sensors to
detect other vehicles.
. The sonar sensors detect station-
ary objects behind the vehicle.
The sonar sensor may not detect:
— Small or moving objects
— Wedge-shaped objects
— Object close to the bumper
(less than approximately 1 ft
(30 cm))
— Thin objects such as rope, wire and chain, etc.
. The brake engagement by the I-
BI system is not as effective on a
slope as it is on flat ground. When
on a steep slope the system may
not function properly.
. Do not use the I-BI system under
the following conditions because
the system may not function properly.
— When driving with a tire that is
not within normal tire condi-
tions (for example, tire wear,
low tire pressure, installation
of spare tire, tire chains, non-
standard wheels).
— When the vehicle is equipped with non-original brake parts
or suspension parts.
. When towing a trailer or other
vehicle, turn the I-BI system off to
prevent the occurrence of an un-
expected accident resulting from
sudden system operation. (See “I-
BI system operation” (P.5-65).)
. Excessive noise (for example,
audio system volume, open vehi-
cle window) will interfere with the
chime sound, and it may not be
heard.

— The vehicle is driving on asteep hill.
— There is an accumulation of snow or ice behind the vehi-
cle.
— An ultrasonic wave source, such as another vehicle’s so-
nar, is near the vehicle.
. Once the automatic brake control
operates, it does not operate
again if the vehicle approaches
the same obstacle.
. The automatic brake control can
only operate for a short period of
time. Therefore, the driver must
depress the brake pedal.
. In the following situations, the
RAB system may not operate
properly or may not function
sufficiently:
— The vehicle is driven in bad
weather (rain, fog, snow, etc.).
— The vehicle is driven on a steep hill.
— The vehicle’s posture is chan- ged (e.g., when driving over a
bump).
— The vehicle is driven on a slippery road. — The vehicle is turned sharply
by turning the steering wheel
fully.
— Snow chains are used.
— Wheels or tires other than NISSAN recommended are
used.
— The brakes are cold at low ambient temperatures or im-
mediately after driving has
started.
— The braking force becomes poor due to wet brakes after
driving through a puddle or
washing the vehicle.
. Turn the RAB system off in the
following conditions to prevent
the occurrence of an unexpected
accident resulting from sudden
system operation:
— The vehicle is towed.
— The vehicle is carried on a
flatbed truck.
— The vehicle is on the chassis dynamometer.
— The vehicle drives on an un- even road surface. — Suspension parts other than
those designated as genuine
parts are used. (If the vehicle
height or the vehicle body
inclination is changed, the
system may not detect an
obstacle correctly.)
. When towing a trailer or other
vehicle, turn the RAB system off
to prevent the occurrence of an
unexpected accident resulting
from sudden system operation.
(See “RAB system operation” (P.5-
118).)
. Excessive noise (e.g., audio sys-
tem volume, an open vehicle win-
dow) will interfere with the chime
sound, and it may not be heard.

illuminates (for 4WD models).
See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-18) and “Vehicle Dynamic
Control (VDC) off indicator light” (P.2-18).
The computer has a built-in diagnostic
feature that tests the system each time
you start the engine and move the vehicle
forward or in reverse at a slow speed.
When the self-test occurs, you may hear a
“clunk” noise and/or feel a pulsation in the
brake pedal. This is normal and is not an
indication of a malfunction.
WARNING
.The VDC system is designed to
help improve driving stability but
does not prevent accidents due
to abrupt steering operation at
high speeds or by careless or
dangerous driving techniques.
Reduce vehicle speed and be
especially careful when driving
and cornering on slippery sur-
faces and always drive carefully.
. Do not modify the vehicle’s sus-
pension. If suspension parts such
as shock absorbers, struts,
springs, stabilizer bars, bushings
and wheels are not NISSAN re-
commended for your vehicle or are extremely deteriorated, the
VDC system may not operate
properly. This could adversely
affect vehicle handling perfor-
mance, and the VDC warning light
may illuminate.
. If brake related parts such as
brake pads, rotors and calipers
are not NISSAN recommended or
are extremely deteriorated, the
VDC system may not operate
properly and the VDC warning
light
may illuminate.
. If engine control related parts are
not NISSAN recommended or are
extremely deteriorated, the VDC
warning light
may illuminate.
. When driving on extremely in-
clined surfaces such as higher
banked corners, the VDC system
may not operate properly and the
VDC warning light
may illumi-
nate. Do not drive on these types
of roads.
. When driving on an unstable sur-
face such as a turntable, ferry,
elevator or ramp, the VDC warn-
ing light
may illuminate. This
is not a malfunction. Restart the
engine after driving onto a stable
surface. .
If wheels or tires other than the
NISSAN recommended ones are
used, the VDC system may not
operate properly and the VDC
warning light
may illuminate.
. The VDC system is not a substi-
tute for winter tires or tire chains
on a snow covered road.

VEHICLE RECOVERY (freeing a stuck
vehicle)
WARNING
.Stand clear of a stuck vehicle.
. Do not spin your tires at high
speed. This could cause them to
explode and result in serious in-
jury. Parts of your vehicle could
also overheat and be damaged.
Pulling a stuck vehicle
If your vehicle is stuck in sand, snow, mud,
etc., use a tow strap or other device
designed specifically for vehicle recovery.
Always follow the manufacturer’s instruc-
tions for the recovery device.
Attach the tow strap to the towing hook.
CAUTION
.Tow chains or cables must be
attached only to the main struc-
tural members of the vehicle or
the towing hooks. Otherwise, the
vehicle body will be damaged.
. Use the towing hook only to free
a vehicle stuck in sand, snow, mud, etc. Never tow the vehicle
for a long distance using only the
towing hook.
. The towing hook is under tre-
mendous force when used to free
a stuck vehicle. Never pull the
hook at an angle.
. Always pull the cable straight out
from the front or rear of the
vehicle.
. Pulling devices should be routed
so they do not touch any part of
the suspension, steering, brake or
cooling systems.
. Pulling devices such as ropes or
canvas straps are not recom-
mended for use in vehicle towing
or recovery.
Rocking a stuck vehicle
If your vehicle is stuck in sand, snow, mud,
etc., use the following procedure:
1. Turn off the Vehicle Dynamic Control
(VDC) system.
2. Make sure the area in front and behind the vehicle is clear of obstruc-
tions.
3. Turn the steering wheel right and left to clear an area around the front tires. 4. Slowly rock the vehicle forward and
backward.
.Shift back and forth between R(Reverse) and D (Drive).
.Apply the accelerator as little as possible to maintain the rocking
motion.
.Release the accelerator pedal be-
fore shifting between R and D.
.Do not spin the tires above 35 MPH(55 km/h).
5. If the vehicle cannot be freed after a few tries, contact a professional tow-
ing service to remove the vehicle.
In case of emergency6-19

.Replacement tires may have a
lower speed rating than the fac-
tory equipped tires, and may not
match the potential maximum
vehicle speed. Never exceed the
maximum speed rating of the
tire.
. Replacing tires with those not
originally specified by NISSAN
could affect the proper operation
of the TPMS.
. For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
All season tires
NISSAN specifies all season tires on some
models to provide good performance all
year, including snowy and icy road con-
ditions. All Season tires are identified by
ALL SEASON and/or M&S (Mud and Snow)
on the tire sidewall. Snow tires have
better snow traction than All Season tires
and may be more appropriate in some
areas.
Summer tires
NISSAN specifies summer tires on some
models to provide superior performance
on dry roads. Summer tire performance is
substantially reduced in snow and ice.
Summer tires do not have the tire trac-
tion rating M&S on the tire sidewall.
If you plan to operate your vehicle in
snowy or icy conditions, NISSAN recom-
mends the use of SNOW tires or ALL
SEASON tires on all four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load
rating to the original equipment tires. If
you do not, it can adversely affect the
safety and handling of your vehicle.
Generally, snow tires will have lower
speed ratings than factory equipped tires
and may not match the potential max-
imum vehicle speed. Never exceed the
maximum speed rating of the tire.
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.
For additional traction on icy roads,
studded tires may be used. However,
some U.S. states and Canadian provinces
prohibit their use. Check local, state and
provincial laws before installing studded tires. Skid and traction capabilities of
studded snow tires, on wet or dry sur-
faces, may be poorer than that of non-
studded snow tires.
TIRE CHAINS
Use of tire chains may be prohibited
according to location. Check the local
laws before installing tire chains. When
installing tire chains, make sure they are
the proper size for the tires on your
vehicle and are installed according to
the chain manufacturer’s suggestions.
Use only SAE Class S chains.
Class “S”
chains are used on vehicles with re-
stricted tire to vehicle clearance. Vehicles
that can use Class “S” chains are designed
to meet the SAE standard minimum
clearances between the tire and the
closest vehicle suspension or body com-
ponent required to accommodate the
use of a winter traction device (tire chains
or cables). The minimum clearances are
determined using the factory equipped
tire size. Other types may damage your
vehicle. Use chain tensioners when re-
commended by the tire chain manufac-
turer to ensure a tight fit. Loose end links
of the tire chain must be secured or
removed to prevent the possibility of
whipping action damage to the fenders
or underbody. If possible, avoid fully load-
ing your vehicle when using tire chains. In
