snow chains INFINITI QX55 2023 Owners Manual

•When using a wheel without the TPMS
such as the spare tire, when a spare tire is
mounted or a wheel is replaced, tire pres-
sure will not be indicated, the TPMS will
not function and the low tire pressure
warning light will flash for approxi-
mately 1 minute. The light will remain on
after 1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you
visit an INFINITI retailer for this service.
• Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
• Do not inject any tire liquid or aerosol tire
sealant into the tires, as this may cause a
malfunction of the tire pressure sensors.
CAUTION
• The TPMS may not function properly
when the wheels are equipped with tire
chains or the wheels are buried in snow.
• Do not place metalized film or any metal
parts (antenna, etc.) on the windows.
This may cause poor reception of the sig-
nals from the tire pressure sensors, and
the TPMS will not function properly. Some devices and transmitters may tempo-
rarily interfere with the operation of the
TPMS and cause the low tire pressure
warning light to illuminate.
Some examples are:
• Facilities or electric devices using similar
radio frequencies are near the vehicle.
• If a transmitter set to similar frequencies is being used in or near the vehicle.
• If a computer (or similar equipment) or a DC/AC converter is being used in or near
the vehicle.
The low tire pressure warning light may illu-
minate in the following cases:
• If the vehicle is equipped with a wheel and tire without TPMS.
• If the TPMS has been replaced and the ID has not been registered.
• If the wheel is not originally specified by INFINITI.

LDP SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the LDP system. Failure to follow the
warnings and instructions for proper use of
the LDP system could result in serious in-
jury or death.
• The LDP system may activate if you
change lanes without first activating
your turn signal or, for example, if a con-
struction zone directs traffic to cross an
existing lane marker. If this occurs you
may need to apply corrective steering to
complete your lane change.
• Because the LDP may not activate under
the road, weather, and lane marker con-
ditions described in this section, it may
not activate every time your vehicle be-
gins to leave its lane and you will need to
apply corrective steering.
• The LDP system will not operate at
speeds below approximately 37 mph (60
km/h) or if it cannot detect lane markers.
• When the LDP system is operating,
avoid excessive or sudden steering ma-
neuvers. Otherwise, you could lose con-
trol of the vehicle. •
Do not use the LDP system under the
following conditions as it may not func-
tion properly:
– During bad weather (rain, fog, snow,
etc.).
– When driving on slippery roads, such
as on ice or snow.

roads.
– When there is a lane closure due to
road repairs.
– When driving in a makeshift or tem-
porary 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, non-standard
wheels).
– When the vehicle is equipped with
non-original brake parts or suspen-
sion parts.
• The system may not function properly
under the following conditions: – On roads where there are multiple

5-98Starting and driving

–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
designated 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.) –
If the vehicle is using an accessory like
a bike rack, or cargo carrier that
blocks the sensors.
• 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 See Owner’s Manual” 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
O1clean.
• If the parking sensors are dirty, wipe them off with a soft cloth while being careful to
not damage them.
• Do not subject the area around the parking sensors
O1to strong impact. Also, do not
remove or disassemble the parking sensors.
If the parking sensors and peripheral areas
are deformed in an accident, etc., have the
sensors checked. It is recommended that
you visit an INFINITI retailer for this service.

Parking brake break-in
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or rotors are replaced, in order to
assure the best brake performance.
This procedure is described in the INFINITI
Service Manual. It is recommended that you
visit an INFINITI retailer for this service.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
• The ABS is a sophisticated device, but it
cannot prevent accidents resulting from
careless or dangerous driving tech-
niques. It can help maintain vehicle con-
trol during braking on slippery surfaces.
Remember that stopping distances on
slippery surfaces will be longer than on
normal surfaces even with ABS. Stop-
ping distances may also be longer on
rough, gravel or snow covered roads, or
if you are using tire chains. Always main-
tain a safe distance from the vehicle in
front of you. Ultimately, the driver is re-
sponsible for safety. •
Tire type and condition may also affect
braking effectiveness.
– When replacing tires, install the
specified size of tires on all four
wheels.
– When installing a spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. For additional in-
formation, see “Tire and Loading In-
formation label” (P. 8-29).
– For additional information, see
“Wheels and tires” (P. 8-27).
The ABS controls the brakes so the wheels do
not lock during hard braking or when braking
on slippery surfaces. The system detects the
rotation speed at each wheel and varies the
brake fluid pressure to prevent each wheel
from locking and sliding. By preventing each
wheel from locking, the system helps the
driver maintain steering control and helps to
minimize swerving and spinning on slippery
surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate to pre- vent the wheels from locking up. Steer the
vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test feature
The Anti-lock Braking System (ABS) includes
electronic sensors, electric pumps, hydraulic
solenoids and a computer. The computer has
a built-in diagnostic feature that tests the
system each time you start the engine and
move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may
hear a “clunk” noise and/or feel a pulsation in
the brake pedal. This is normal and does not
indicate a malfunction. If the computer
senses a malfunction, it switches the ABS off
and illuminates the ABS warning light on the
instrument panel. The brake system then op-
erates normally but without anti-lock
assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the vehicle
checked. It is recommended that you visit an
INFINITI retailer for this service.
5-140Starting and driving

•When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the
indicator light may flash
or both theandindicator
lights may illuminate. This is not a mal-
function. Restart the engine after driv-
ing onto a stable surface.
• If wheels or tires other than the INFINITI
recommended ones are used, the VDC
system may not operate properly and
the
indicator light may flash or both
theandindicator lights may
illuminate.
• The VDC system is not a substitute for
winter tires or tire chains on a snow cov-
ered road.
BRAKE FORCE DISTRIBUTION
During braking while driving through turns,
the system optimizes the distribution of force
to each of the four wheels depending on the
radius of the turn.
WARNING
• The VDC system is designed to help the
driver maintain controllability but does
not prevent accidents due to abrupt
steering operation at high speeds or by
careless or dangerous driving tech-
niques. Reduce vehicle speed and be es-
pecially careful when driving and corner-
ing on slippery surfaces and always drive
carefully.
• Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not INFINITI
recommended for your vehicle or are ex-
tremely deteriorated, the VDC system
may not operate properly. This could ad-
versely affect vehicle handling perfor-
mance, and the
indicator light may
flash or both theandindicator
lights may illuminate.
• If brake related parts such as brake pads,
rotors and calipers are not INFINITI rec-
ommended or are extremely deterio-
rated, the VDC system may not operate
properly and both the
and theindicator lights may illuminate. •
If engine control related parts are not
INFINITI recommended or are extremely
deteriorated, both the
andindicator lights may illuminate.
• When driving on extremely inclined sur-
faces such as higher banked corners, the
VDC system may not operate properly
and the
indicator light may flash or
both theandindicator lights
may illuminate. Do not drive on these
types of roads.
• When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the
indicator light may flash
or both theandindicator
lights may illuminate. This is not a mal-
function. Restart the engine after driv-
ing onto a stable surface.
• If wheels or tires other than the INFINITI
recommended ones are used, the VDC
system may not operate properly and
the
indicator light may flash or both
theandindicator lights may
illuminate.
• The VDC system is not a substitute for
winter tires or tire chains on a snow cov-
ered road.

FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock be-
comes frozen, heat the key before inserting it
into the key hole, or use the INFINITI Intelli-
gent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper winter
protection. For additional information, see
“Engine cooling system” (P. 8-4).
BATTERY
If the battery is not fully charged during ex-
tremely 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. 8-12).
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, see
“Changing engine coolant” (P. 8-5).
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 operate
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 information.
2. For additional traction on icy roads, stud- ded tires may be used. However, some
U.S. states and Canadian provinces pro-
hibit their use. Check local, state and pro-
vincial 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.
3. Tire chains may be used. For additional information, see “Tire chains”(P. 8-37).
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 snowdrifts.
• 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
caution. 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.
COLD WEATHER DRIVING
Starting and driving5-153

All-Wheel Drive (AWD) models with
Continuously Variable Transmission
(CVT)
INFINITI recommends that towing dollies be
used when towing your vehicle or place the
vehicle on a flatbed truck as illustrated.
CAUTION
Never tow AWD models equipped with a
Continuously Variable Transmission (CVT)
with any of the wheels on the ground as
this may cause serious and expensive dam-
age to the transfer case and transmission.
NOTE:
If the battery is completely drained the
transmission will not manually shift to other
positions.
VEHICLE RECOVERY (freeing a
stuck vehicle)
WARNING
To avoid vehicle damage, serious personal
injury or death when recovering a stuck
vehicle: •
Contact a professional towing service to
recover the vehicle if you have any ques-
tions regarding the recovery procedure.
• Tow chains or cables must be attached
only to main structural members of the
vehicle.
• Do not use the vehicle tie-downs to tow
or free a stuck vehicle.
• Only use devices specifically designed for
vehicle recovery and follow the manu-
facturer's instructions.
• Always pull the recovery device straight
out from the front of the vehicle. Never
pull at an angle.
• Route recovery devices so they do not
touch any part of the vehicle except the
attachment point.
If your vehicle is stuck in sand, snow, mud,
etc., use a tow strap or other device designed
specifically for vehicle recovery. Always fol-
low the manufacturer's instructions for the
recovery device.
