Precautions for Blind Spot WarningINFOID:0000000006223856
SIDE RADAR HANDLING
 Side radar for BSW system is located inside the rear bumper.
 Always keep the rear bumper near the side radar clean.
 Do not attach a sticker (including transparent material), install an accessory or paintwork near the side radar.
 Do not strike or damage the areas around the side radar.
 Do not strike, damage, and scratch the side radar, especially the vent seal (gray circular) area, under repair.
PRECAUTIONS FOR BLIND SPOT WARNING
 The BSW system is not a replacement for proper driving procedure and are not designed to prevent contact
with vehicles or objects. When changing lanes, always us e the side and rear mirrors and turn and look in the
direction driver will move to ensure it is safe to change lanes. Never rely solely on the BSW system.
 The BSW system may not provide a warning for v ehicles that pass through the detection zone quickly.
 Do not use the BSW system when towing a trai ler because the system may not function properly.
 Excessive noise (e.g. audio system volume, open vehicle window) will interfere with the chime sound, and it may not be heard.
 The side radar may not be able to detect and activate BSW when certain objects are present such as:
- Pedestrians, bicycles, animals.
- Several types of vehicles such as motorcycles.
- Oncoming vehicles.
- Vehicles remaining in the detection z one when driver accelerate from a stop.
- A vehicle merging into an adjacent lane at a speed approximately the same as vehicle.
- A vehicle approaching rapidly from behind.
- A vehicle which vehicle overtakes rapidly.
 Severe weather or road spray conditions may reduce t he ability of the side radar to detect other vehicles.
 The side radar detection zone is designed based on a standard lane width. When driving in a wider lane, the
side radar may not detect vehicles in an adjacent lane. When driving in a narrow lane, the side radar may
detect vehicles driving two lanes away.
 The side radar are designed to ignore most stationary objects, however objects such as guardrails, walls,
foliage and parked vehicles may occasionally be det ected. This is a normal operating condition.

Tow Truck TowingINFOID:0000000006280880
CAUTION:
 All applicable local laws regarding the towing operation must be obeyed.
 It is necessary to use proper towi ng equipment to avoid possible damage to the vehicle during tow-
ing operation. To wing is in accordance with Towing Procedure Manual at dealer.
 Always attach safety chains before towing.
 When towing, check that the transmission, steering syst em and powertrain are in good order. If any
unit is damaged, dollies must be used.
 Never tow automatic transmission model from the rear (that is backward) with four wheels on the
ground. This may cause serious and exp ensive damage to the transmission.
4WD MODELS
NISSAN recommends that a dolly be used as illustrated when towing 4WD models.
CAUTION:
Never tow 4WD models with any of the wheels on the ground as this may cause serious and expensive
damage to the powertrain.
Vehicle Recovery (Freeing a Stuck Vehicle)INFOID:0000000006280881
FREEING TRAPPED VEHICLE
WARNING:
 Stand clear of a stuck vehicle.
 Never allow anyone to stand near the towing line during the pulling operation.
 Never spin your tires at high sp eed. This could cause them to explode and result in serious injury.
Parts of your vehicle could also overheat and be damaged.
CAUTION:
 Tow chains or cables must be attached only to the vehicle recovery hooks or main structural mem-
bers of the vehicle. Otherwise, the vehicle body will be damaged.
 Never use the vehicle tie downs to free a vehicle st uck in sand, snow, mud, etc. Never tow the vehi-
cle using the vehicle tie downs or recovery hooks.
 Always pull the cable straight out from the front of the vehicle. Never pull on the hook at an angle.

AUTOMATIC TRANSMISSION
To tow a vehicle equipped with an automatic tr ansmission, an appropriate vehicle dolly MUST be placed under
the towed vehicle's drive wheels. Always follow the dolly manufacture's recommendations when using their
product.
If the vehicle is stuck in sand, snow , mud, etc., use the following procedure:
1. Turn off the Vehicle Dynam ic Control System. (if equipped)
2. Check the area in front and behind the vehicle is clear of obstructions.
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 before shifting between R and D.
Do not spin the tires above 35 mph. (55 km/h).
5. If the vehicle can not be freed after a few tries, cont act a professional towing service to remove the vehi-
cle.

one or more of the following driving conditions:
 Repeated short trips of less than 5 miles (8 km).
 Repeated short trips of less than 10 miles (16 km) with outside temperatures
remaining below freezing.
 Operating in hot weather in stop-and-go “rush hour” traffic.
 Extensive idling and/or low speed driving for long distances, such as police, taxi
or door-to-door delivery use.
