sparks near the vehicle when refuel-
ing.
. Do not attempt to top off the fuel
tank after the fuel pump nozzle shuts
off automatically. Continued refuel-
ing may cause fuel overflow, resulting
in fuel spray and possibly a fire.
. Use only an original equipment type
fuel-filler cap as a replacement. It has
a built-in safety valve needed for
proper operation of the fuel system
and emission control system. An in-
correct cap can result in a serious
malfunction and possible injury. It
could also cause the malfunction
indicator light to come on.
. Never pour fuel into the throttle body
to attempt to start your vehicle.
. Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable
fuel containers:
— Always place the container on the ground when filling.
— Do not use electronic devices when filling. — Keep the pump nozzle in contact
with the container while you are
filling it.
— Use only approved portable fuel containers for flammable liquid.
CAUTION
. If fuel is spilled on the vehicle body,
flush it away with water to avoid
paint damage.
. Insert the cap straight into the fuel-
filler tube, then tighten until the fuel-
filler cap clicks. Failure to tighten the
fuel-filler cap properly may cause the
malfunction indicator light (MIL)
to illuminate. If thelight illumi-
nates because the fuel-filler cap is
loose or missing, tighten or install the
cap and continue to drive the vehicle.
The
light should turn off after a
few driving trips. If thelight does
not turn off after a few driving trips,
have the vehicle inspected. It is
recommended you visit an INFINITI
retailer for this service.
. The Loose Fuel Cap warning will
appear if the fuel-filler cap is not
properly tightened. It may take a few driving trips for the message to be
displayed. Failure to tighten the fuel-
filler cap properly after the Loose
Fuel Cap warning appears may cause
the
Malfunction Indicator Light
(MIL) to illuminate.
Turn the cap counterclockwise to remove.
To tighten, turn the cap clockwise until a
single click is heard.

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.8-35).
For four-wheel drive
If you install snow tires, they must also be
the same size, brand, construction and tread
pattern on all four wheels.
SPECIAL WINTER EQUIPMENT
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
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 down-
shifting 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 pave-
ment.
. 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 steer-
ing maneuvers.
. Do not use the cruise control on
slippery roads.
. Snow can trap dangerous exhaust
gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist in
cold temperature starting.
The engine block heater should be used
when the outside temperature is 20°F
(−7°C) or lower.
