– On roads where there are sharply con-trasting objects, such as shadows,
snow, water, wheel ruts, seams or
lines remaining after road repairs.
– 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 adheres 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 cam- era unit (e.g., light directly shines on
the front of the vehicle at sunrise or
sunset).
– When a sudden change in brightness occurs (e.g., when the vehicle enters or
exits a tunnel or under a bridge). ∙ Do not use the BSI system under the fol-
lowing conditions because the system
may not function properly:
– During bad weather (e.g., 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 lane.
– When driving on roads where the lane width is too narrow.
– When driving with a tire that is not within normal tire conditions (e.g., tire
wear, low tire pressure, installation of
spare tire, tire chains, nonstandard
wheels).
– When the vehicle is equipped with non-original brake parts or suspen-
sion parts.
∙ Do not use the BSI system when towing a trailer. ∙ Excessive noise (e.g., audio system vol-
ume, open vehicle window) will interfere
with the chime sound, and it may not be
heard.

5-72Starting and driving

– The vehicle’s posture is changed (e.g.,when driving over a bump).
– The vehicle is driven on a slippery road.
– The vehicle is turned sharply by turn- ing the steering wheel fully.
– Snow chains are used.
– Wheels or tires other than INFINITI recommended are used.
– The brakes are cold at low ambient temperatures or immediately 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 uneven road surface. –Suspension parts other than those des-
ignated as Genuine INFINITI parts are
used. (If the vehicle height or the vehicle
body inclination is changed, the system
may not detect an obstacle correctly.)
∙ Excessive noise (e.g., audio system vol-
ume, an open vehicle window) will inter-
fere with the chime sound, and it may not
be heard.
SYSTEM MALFUNCTION
If the RAB system malfunctions, it will be
turned off automatically, the RAB system
warning light will illuminate, and the “System
fault” warning message will appear in the
vehicle information display.
Action to take
If the warning light illuminates, park the ve-
hicle in a safe location, turn the engine off,
and restart the engine. If the warning light
continues to illuminate, have the RAB system
checked. It is recommended that you visit an
INFINITI retailer for this service.
NOTE:
If the RAB system cannot be operated tem-
porarily, the RAB system warning light
blinks.
SYSTEM MAINTENANCE
Observe the following items to ensure proper
operation of the system:
∙ Always keep the parking sensors

Follow these easy-to-use Fuel Efficient Driv-
ing Tips to help you achieve the most fuel
economy from your vehicle.1. Use Smooth Accelerator and Brake
Pedal Application
∙ Avoid rapid starts and stops.
∙ Use smooth, gentle accelerator and brake application whenever possible.
∙ Maintain constant speed while com- muting and coast whenever possible.
2. Maintain Constant Speed
∙ Look ahead to try and anticipate and minimize stops.
∙ Synchronizing your speed with traffic lights allows you to reduce your num-
ber of stops.
∙ Maintaining a steady speed can mini- mize red light stops and improve fuel
efficiency.
3. Use Air Conditioning (A/C) at Higher
Vehicle Speeds
∙ Below 40 mph (64 km/h), it is more efficient to open windows to cool the
vehicle due to reduced engine load. ∙ Above 40 mph (64 km/h), it is more
efficient to use A/C to cool the vehicle
due to increased aerodynamic drag.
∙ Recirculating the cool air in the cabin when the A/C is on reduces cooling
load.
4. Drive at Economical Speeds and Dis-
tances
∙ Observing the speed limit and not ex- ceeding 60 mph (97 km/h) (where le-
gally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag.
∙ Maintaining a safe following distance behind other vehicles reduces unnec-
essary braking.
∙ Safely monitoring traffic to anticipate changes in speed permits reduced
braking and smooth acceleration
changes.
∙ Select a gear range suitable to road conditions.
5. Use Cruise Control
∙ Using cruise control during highway driving helps maintain a steady speed. ∙ Cruise control is particularly effective
in providing fuel savings when driving
on flat terrains.
6. Plan for the Shortest Route
∙ Utilize a map or navigation system to determine the best route to save time.
7. Avoid Idling
∙ Shutting off your engine when safe for stops exceeding 30–60 seconds saves
fuel and reduces emissions.
8. Buy an Automated Pass for Toll Roads
∙ Automated passes permit drivers to use special lanes to maintain cruising
speed through the toll and avoid stop-
ping and starting.
9. Winter Warm Up
∙ Limit idling time to minimize impact to fuel economy.
∙ Vehicles typically need no more than 30 seconds of idling at start-up to ef-
fectively circulate the engine oil before
driving.
∙ Your vehicle will reach its ideal operat- ing temperature more quickly while
driving versus idling.
FUEL EFFICIENT DRIVING TIPS
5-172Starting and driving

10.Keeping your Vehicle Cool
∙ Park your vehicle in a covered parking area or in the shade whenever pos-
sible.
∙ When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system. ∙ Keep your engine tuned up.
∙ Follow the recommended scheduled
maintenance.
∙ Keep the tires inflated to the correct pressure. Low tire pressure increases tire
wear and lowers fuel economy.
∙ Keep all the wheels in correct alignment. Improper alignment increases tire wear
and lowers fuel economy.
∙ Use the recommended viscosity engine oil. For additional information, refer to
“Engine oil and oil filter recommenda-
tions” in the “Technical and consumer in-
formation” section of this manual. If any malfunction occurs in the Intelligent
AWD system while the engine is running,
messages are displayed in the meter.

The sonar system sounds a tone to inform the
driver of obstacles near the bumper.
When the sonar system is turned on, the
sonar view will automatically appear in the
center display when the camera is activated.
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the sonar system
could result in serious injury or death.
∙ The sonar system is not a replacement forproper driving procedures and is not de-
signed to prevent contact with vehicles
or objects. ∙ The driver is always responsible for
safety during parking and other maneu-
vers. Always look around and check that
it is safe to do so before parking.
∙ This function is designed as an aid to the driver in detecting large stationary ob-
jects to help avoid damaging the vehicle.
If your vehicle sustains damage to the bum-
per fascia, leaving it misaligned or bent, the
sensing zone may be altered causing inaccu-
rate measurement of obstacles or false
alarm.
CAUTION
∙ Excessive noise (such as audio system volume or an open vehicle window) will
interfere with the tone and it may not be
heard.
∙ Keep the sonar sensors (located on the bumper fascias) free from snow, ice and
large accumulations of dirt. Do not clean
the sensors with sharp objects. If the sen-
sors are covered, the accuracy of the so-
nar function will be diminished.
SYSTEM OPERATION
The system informs with a visual and audible
signal of front obstacles when the shift lever
is in the D (Drive) position and both front and
rear obstacles when the shift lever is in the R
(Reverse) position.

The system is deactivated at speeds above
6 mph (10 km/h). It is reactivated at lower
speeds.
The intermittent tone will stop after 3 sec-
onds when an obstacle is detected by only
the corner sensor and the distance does not
change. The tone will stop when the obstacle
get away from the vehicle.

DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For additional information, refer to
“Changing engine coolant” in the “Do-it-
yourself” section of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
INFINITI recommends the use of MUD &
SNOW or ALL SEASON TIRES on all
four wheels. It is recommended that you
visit an INFINITI retailer for the tire type,
size, speed rating and availability infor-
mation.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing studded tires. Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow tires.
3. Tire chains may be used. For additional information, refer to “Tire chains” in the
“Do-it-yourself” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
∙ A scraper and stiff-bristled brush to re- move ice and snow from the windows
and wiper blades.
∙ A sturdy, flat board to be placed under the jack to give it firm support.
∙ A shovel to dig the vehicle out of snow- drifts.
∙ Extra washer fluid to refill the windshield-washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
∙ Wet ice (32°F, 0°C and freezing rain),very cold snow or ice can be slick and very
hard to drive on. The vehicle will have
much less traction or “grip” under these
conditions. Try to avoid driving on wet
ice until the road is salted or sanded.
∙ Whatever the condition, drive with cau- tion. Accelerate and slow down with
care. If accelerating or downshifting too
fast, the drive wheels will lose even more
traction.
∙ Allow more stopping distance under these conditions. Braking should be
started sooner than on dry pavement.
∙ Allow greater following distances on slippery roads.
∙ Watch for slippery spots (glare ice). These may appear on an otherwise clear
road in shaded areas. If a patch of ice is
seen ahead, brake before reaching it. Try
not to brake while on the ice, and avoid
any sudden steering maneuvers.
∙ Do not use the cruise control on slippery roads.
5-192Starting and driving

CAUTION
∙ Continuously Variable Transmission(CVT) models cannot be push-started or
tow-started. Attempting to do so may
cause transmission damage.
∙ Do not push start this vehicle. The three- way catalyst may be damaged.
WARNING
∙ Do not continue to drive if your vehicleoverheats. Doing so could cause engine
damage or a vehicle fire.
∙ To avoid the danger of being scalded, never remove the coolant reservoir cap
while the engine is still hot. When the
coolant reservoir cap is removed, pres-
surized hot water will spurt out, possibly
causing serious injury.
∙ Do not open the hood if steam is coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading),
or if you feel a lack of engine power, detect
abnormal noise, etc. take the following steps. 1. Move the vehicle safely off the road, apply the parking brake and engage the
P (Park) position.
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed. 3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. (If
steam or coolant is escaping, turn off the
engine.) Do not open the hood further
until no steam or coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the engine,
stand clear to prevent getting burned.
5. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leak-
ing, the water pump belt is missing or
loose, or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling fan
can start at any time.
