To lock, close the fuel-filler door securely and
lock all doors by operating the door handle
request switch, the LOCK button on the Intelli-
gent Key, the mechanical key or the power door
lock switch.
FUEL-FILLER CAP
WARNING
●Gasoline is extremely flammable and highly
explosive under certain conditions. You
could be burned or seriously injured if it is
misused or mishandled. Always stop engine
and do not smoke or allow open flames or
sparks near the vehicle when refueling.
● Do not attempt to top off the fuel tank after
the fuel pump nozzle shuts off automati-
cally. Continued refueling may cause fuel
overflow, resulting in fuel spray and possi-
bly 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 sys-
tem. An incorrect cap can result in a serious
malfunction and possible injury. It could
also cause
the malfunction indicator
light (MIL) to come on. ●
Never pour fuel into the throttle body to at-
tempt 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 contain- ers 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 the
light illuminates because the fuel-
filler cap is loose or missing, tighten or in-
stall the cap and continue to drive the ve-
hicle. The
light should turn off after a
few driving trips. If the
light does not
turn off after a few driving trips, have the
vehicle inspected by an INFINITI retailer.
● If your vehicle is equipped with the LOOSE
FUEL CAP warning, the LOOSE FUEL CAP
warning will illuminate if the fuel-filler cap is
not properly tightened. Failure to tighten the
fuel-filler cap properly after the LOOSE FUEL
CAP warning illuminates may cause the
malfunction indicator light (MIL) to
illuminate.

TIRE EQUIPMENT
SUMMER tires have a tread designed to provide
superior performance on dry pavement. How-
ever, the performance of these tires will be
substantially reduced in snowy and icy condi-
tions. 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 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” in the “8. Maintenance and do-it-
yourself” section of this manual.
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 reser-
voir 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 accel-
erating 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 slip-
pery 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 un-
der your vehicle. Keep snow clear of the ex-
haust pipe and from around your vehicle.
