7. Avoid idling..Shutting off your engine when safefor stops exceeding 30-60 seconds
saves fuel and reduces emissions.
8. Buy an automated pass for toll roads.
.Automated passes permit drivers to use special lanes to maintain cruis-
ing speed through the toll and
avoid stopping and starting.
9. Winter warm up.
.Limit idling time to minimize impact to fuel economy.
.Vehicles typically need no morethan 30 seconds of idling at start-
up to effectively circulate the en-
gine oil before driving.
.Your vehicle will reach its ideal
operating temperature more
quickly while driving versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered parking area or in the shade when-
ever possible.
.When entering a hot vehicle, open- ing the windows will help to reduce
the inside temperature faster, re-
sulting in reduced demand on your
A/C system. .
Keep your engine tuned up.
. Follow the recommended scheduled
maintenance.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases
tire wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire
wear and lowers fuel economy.
. Use the recommended viscosity en-
gine oil. (See “Engine oil and oil filter
recommendation” (P.10-6).)
WARNING
.Do not attempt to raise two
wheels off the ground and shift
the transmission to any drive or
reverse position with the engine
running. Doing so may result in
drivetrain damage or unexpected
vehicle movement which could
result in serious vehicle damage
or personal injury.
. Do not attempt to test a 4WD
equipped vehicle on a 2-wheel
dynamometer or similar equip-
ment even if the other two
wheels are raised off the ground.
Make sure you inform test facility
personnel that your vehicle is
equipped with 4WD before it is
placed on a dynamometer. Using
the wrong test equipment may
result in drivetrain damage or
unexpected vehicle movement
which could result in serious ve-
hicle damage or personal injury.
INCREASING FUEL ECONOMYNISSAN ALL-MODE 4WD® (if so equipped)

illuminates (for 4WD models).
See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-18) and “Vehicle Dynamic
Control (VDC) off indicator light” (P.2-18).
The computer has a built-in diagnostic
feature that tests the system each time
you start the engine and move the vehicle
forward or in reverse at a slow speed.
When the self-test occurs, you may hear a
“clunk” noise and/or feel a pulsation in the
brake pedal. This is normal and is not an
indication of a malfunction.
WARNING
.The VDC system is designed to
help improve driving stability but
does not prevent accidents due
to abrupt steering operation at
high speeds or by careless or
dangerous driving techniques.
Reduce vehicle speed and be
especially careful when driving
and cornering on slippery sur-
faces and always drive carefully.
. Do not modify the vehicle’s sus-
pension. If suspension parts such
as shock absorbers, struts,
springs, stabilizer bars, bushings
and wheels are not NISSAN re-
commended for your vehicle or are extremely deteriorated, the
VDC system may not operate
properly. This could adversely
affect vehicle handling perfor-
mance, and the VDC warning light
may illuminate.
. If brake related parts such as
brake pads, rotors and calipers
are not NISSAN recommended or
are extremely deteriorated, the
VDC system may not operate
properly and the VDC warning
light
may illuminate.
. If engine control related parts are
not NISSAN recommended or are
extremely deteriorated, the VDC
warning light
may illuminate.
. When driving on extremely in-
clined surfaces such as higher
banked corners, the VDC system
may not operate properly and the
VDC warning light
may illumi-
nate. Do not drive on these types
of roads.
. When driving on an unstable sur-
face such as a turntable, ferry,
elevator or ramp, the VDC warn-
ing light
may illuminate. This
is not a malfunction. Restart the
engine after driving onto a stable
surface. .
If wheels or tires other than the
NISSAN recommended ones are
used, the VDC system may not
operate properly and the VDC
warning light
may illuminate.
. The VDC system is not a substi-
tute for winter tires or tire chains
on a snow covered road.

TIRE EQUIPMENT
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,
NISSAN recommends the use of MUD &
SNOW or ALL SEASON tires on all four
wheels. It is recommended you consult a
NISSAN dealer 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 win-
dows 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
downshifting too fast, the drive
wheels will lose even more trac-
tion.
. Allow more stopping distance
under these conditions. Braking
should be started sooner than on
dry pavement.
. 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 steering
maneuvers.
. Do not use the cruise control on
slippery roads.
. Snow can trap dangerous ex-
haust gases under your vehicle.
Keep snow clear of the exhaust
pipe and from around your vehi-
cle.

.Replacement tires may have a
lower speed rating than the fac-
tory equipped tires, and may not
match the potential maximum
vehicle speed. Never exceed the
maximum speed rating of the
tire.
. Replacing tires with those not
originally specified by NISSAN
could affect the proper operation
of the TPMS.
. For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
All season tires
NISSAN specifies all season tires on some
models to provide good performance all
year, including snowy and icy road con-
ditions. All Season tires are identified by
ALL SEASON and/or M&S (Mud and Snow)
on the tire sidewall. Snow tires have
better snow traction than All Season tires
and may be more appropriate in some
areas.
Summer tires
NISSAN specifies summer tires on some
models to provide superior performance
on dry roads. Summer tire performance is
substantially reduced in snow and ice.
Summer tires do not have the tire trac-
tion rating M&S on the tire sidewall.
If you plan to operate your vehicle in
snowy or icy conditions, NISSAN recom-
mends the use of SNOW tires or ALL
SEASON tires on all four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load
rating to the original equipment tires. If
you do not, it can adversely affect the
safety and handling of your vehicle.
Generally, snow tires will have lower
speed ratings than factory equipped tires
and may not match the potential max-
imum vehicle speed. Never exceed the
maximum speed rating of the tire.
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.
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 sur-
faces, may be poorer than that of non-
studded snow tires.
TIRE CHAINS
Use of tire chains may be prohibited
according to location. Check the local
laws before installing tire chains. When
installing tire chains, make sure they are
the proper size for the tires on your
vehicle and are installed according to
the chain manufacturer’s suggestions.
Use only SAE Class S chains.
Class “S”
chains are used on vehicles with re-
stricted tire to vehicle clearance. Vehicles
that can use Class “S” chains are designed
to meet the SAE standard minimum
clearances between the tire and the
closest vehicle suspension or body com-
ponent required to accommodate the
use of a winter traction device (tire chains
or cables). The minimum clearances are
determined using the factory equipped
tire size. Other types may damage your
vehicle. Use chain tensioners when re-
commended by the tire chain manufac-
turer to ensure a tight fit. Loose end links
of the tire chain must be secured or
removed to prevent the possibility of
whipping action damage to the fenders
or underbody. If possible, avoid fully load-
ing your vehicle when using tire chains. In
