CAUTIONKeep the interior of the vehicle as quiet as
possible to hear the tone clearly.
The sonar system sounds a tone to warn
the driver of obstacles near the bumper.
When the “ Sonar Display ” key is ON, the
sonar indicator will also appear in the
center display. (See “ Sonar indicator ” (P.5-
49).) The system detects rear obstacles
when the selector lever is in the “ R ”
(Reverse) position.
The system may not detect objects at
speeds above 6 MPH (10 km/h) and may
not detect certain angular or moving
objects.
The sonar system detects obstacles up to
3.9 feet (1.2 m) from the bumper with a
decreased coverage area at the outer
corners of the bumper. Refer to the
illustration for approximate zone coverage
areas. As you move closer to the obstacle,
the rate of the tone increases. When the
obstacle is less than 11.8 in (30 cm) away, the tone will sound continuously.
Keep the corner/center sonar (located on
the bumper fascia) free from snow, ice and
large accumulations of dirt (do not clean
the sonar with sharp objects). If the sonar
is covered, it will affect the accuracy of the
sonar system.
The sensitivity level of the corner/center
sonar can be adjusted (higher or lower) in
the SONAR setting display. (See “ How to
use SETTING button ” (P.4-14) for the
“ Sonar ” settings.) SSD0928

ANTIFREEZE GUID-F8D7961D-C579-4F53-826C-B5C0F179A8A4
In the winter when it is anticipated that the
outside temperature will drop below 32 8 F
(0 8 C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “ Engine cooling system ” (P.8-9).
BATTERY GUID-7370DBB5-3733-4F67-B170-202B0ECEAFD5
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “ Battery ”
(P.8-17).
DRAINING OF COOLANT WATER GUID-1E2017DE-B388-4F4A-AC44-3F639AB39240
If the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“ Engine cooling system ” (P.8-9). TIRE EQUIPMENT GUID-CB13ADAD-1389-4CA9-89D4-C970D4152E81
SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your
vehicle on snowy or icy roads, INFINITI
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels.
Consult an INFINITI retailer for the tire
type, size, speed rating and availability
information.
For additional traction on icy roads,
studded tires may be used. However, some
U.S. states and Canadian provinces prohi-
bit their use. Check local, state and
provincial laws before installing 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.
Tire chains may be used. For details, see
“ Tire chains ” (P.8-39) of this manual.
For all-wheel drive GUID-7A027A3E-CFDC-48CE-8A84-86EFBDFF0BCB
If you install snow tires, they must also be
the same size, brand, construction and
tread pattern on all four wheels. SPECIAL WINTER EQUIPMENT GUID-6AEDC1F1-78E0-49EE-A495-05AD7B0A46B7
It is recommended that the following items
be carried in the vehicle during winter:
. A scraper and stiff-bristled brush to
remove 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
snowdrifts.
. Extra window washer fluid to refill the
reservoir tank.
DRIVING ON SNOW OR ICE GUID-0864712C-2A8E-4B2A-96E7-B1801A0D999A
WARNING . Wet ice (32 8 F, 0 8 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 evenCOLD WEATHER DRIVING

[ Edit: 2012/ 1/ 17 Model: V36-D ]8-6 Maintenance and do-it-yourselfdripping from the air conditioner after use
is normal. If you should notice any leaks or
if gasoline fumes are evident, check for the
cause and have it corrected immediately.
Power steering fluid level* and lines:
Check the level when the fluid is cold,
with the engine off. Check the lines for
proper attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust.
It is very important to remove these
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information,
see “ Cleaning exterior ” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir. GUID-DA5BC1C7-4A3F-402D-B20E-D7AF3C2C5866
