•After a short time, hill start assist will no
longer brake your vehicle and it could
roll away There is a risk of an accident
and injury. Therefore, quickly move your
foot from the brake pedal to the accel-
erator pedal. Never leave the vehicle
when it is held by hill start assist.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It
holds the vehicle for a short time after you
have removed your foot from the brake
pedal. This gives you enough time to move
your foot from the brake pedal to the accel-
erator pedal and depress it before the vehicle
begins to roll.
Hill start assist is not active if
•You are pulling away on a level road or a
downhill gradient.
•On vehicles with automatic transmission,
the transmission is in position N.
•The electric parking brake is applied.
•VDC is malfunctioning.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer 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".
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 details, see
"Battery" of this manual.
DRAINING OF ENGINE COOLANT
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, see "Changing engine
coolant" of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide 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.
COLD WEATHER DRIVING
5-96Starting and driving

•When a replacement tire is mounted or a
wheel is replaced, the TPMS will not
function and the low tire pressure warn-
ing light will flash for approximately
1 minute. The light will remain on after
1 minute. It is recommended you Con-
tact an INFINITI retailer as soon as pos-
sible for tire replacement and/or system
resetting.
•Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
•If you used Emergency Tire Sealant to
repair a minor tire puncture, the TPMS
sensor should be checked when repair-
ing or replacing the tire. It is recom-
mended you visit an INFINITI retailer for
this service.
The Tire Pressure Monitoring System (TPMS)
monitors tire pressure of all tires. When the
low tire pressure warning light is lit, and a tire
pressure-related warning (if equipped) ap-
pears in the vehicle information display, one
or more of your tires is significantly under-
inflated. If the vehicle is being driven with low
tire pressure, the TPMS will activate and
warn you of it by the low tire pressure warn-
ing light (in the meter panel). This system willactivate only when the vehicle is driven at
speeds above 16 MPH (25 km/h).
For more details about the TPMS, see "Tire
Pressure Monitoring System (TPMS)".

solution contains rust and corrosion inhibi-
tors, therefore additional cooling system
additives are not necessary.
•Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused by
high-pressure fluid escaping from the
radiator. For additional information on
precautions, refer to "If your vehicle
overheats"
•The engine coolant reservoir tank is
equipped with a pressure type cap. To
prevent engine damage, use only a
genuine INFINITI pressure cap.
CAUTION
•Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause dam-
age to the engine, transmission and/or
cooling system.NIC2833
