automatically stopping during the same
journey.
. Whenever the Idling Stop System is
deactivated the indicator light
on the
Idling Stop OFF switch illuminates. In
this condition the Idling Stop System
cannot prevent unnecessary fuel con-
sumption, exhaust emissions, or noise
during your journey.
. If the Idling Stop System is malfunction-
ing, the indicator light
on the Idling
Stop OFF switch illuminates.
NOTE:
The Idling Stop System ON or OFF message
is displayed for a few seconds in the vehicle
information display when the Idling Stop
OFF switch is pushed. See “Idling Stop
System ON or OFF” (P.5-139).
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock
becomes frozen, heat the key before insert-
ing it into the key hole or use the Intelligent
Key system.
ANTIFREEZE
In the winter when it is anticipated that the
outside temperature will drop below 32°F
(0°C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system (for
VR30DDTT engine models)” (P.8-6), “En-
gine cooling system (for 2.0L turbo gasoline
engine models)” (P.8-8) or “Intercooler cool-
ing system (for VR30DDTT engine models)”
(P.8-9).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly. For
additional information, see “Battery” (P.8-
16).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For details, see “Engine cooling
system (for VR30DDTT engine models)”
(P.8-6) or “Engine cooling system (for 2.0L
turbo gasoline engine models)” (P.8-8).
TIRE EQUIPMENT
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. It is
recommended you consult an INFINITI re-
tailer 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 prohibit 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.8-40) of this manual.
Starting and driving5-141
COLD WEATHER DRIVING

Do not use excessive force.
9. Refill engine with recommended oil and install the oil filler cap securely.
See “Capacities and recommended
fluids/lubricants” (P.10-2) for drain and
refill capacity. The drain and refill capa-
city depends on the oil temperature and
drain time. Use these specifications for
reference only. Always use the dipstick
to determine the proper amount of oil in
the engine.
10. Start the engine and check for leakage around the drain plug and the oil filter.
Correct as required.
11. Turn the engine off and wait more than 15 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
After the operation
1. Install the engine undercover into posi-tion as the following steps.
a. Pull the center of the small plastic clip
out.
b. Hold the engine undercover into posi- tion.
c. Insert the clip through the undercover into the hole in the frame, then push
the center of the clip in to lock the clip
in place. d. Install the other bolts that hold the
undercover in place. Be careful not to
strip the bolts or over-tighten them.
2. Lower the vehicle carefully to the ground.
3. Dispose of waste oil and filter properly.
WARNING
. Prolonged and repeated contact with
used engine oil may cause skin cancer.
. Try to avoid direct skin contact with
used oil. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
. Keep used engine oil out of reach of
children. When checking or replacement is required,
we recommend an INFINITI retailer for
servicing.
CAUTION
.
It is recommended that you use only
Genuine NISSAN Matic S ATF. Do
not mix with other fluids.
. Using automatic transmission fluid
other than Genuine NISSAN Matic S
ATF may cause deterioration in dri-
veability and automatic transmission
durability, and may damage the
automatic transmission. Damage
caused by the use of fluid other than
as recommended is not covered by
the INFINITI new vehicle limited
warranty.
