4. Drive at economical speeds and dis-
tances.
.Observing the speed limit and not
exceeding 60 MPH (97 km/h) (where
legally allowed) can improve fuel
efficiency due to reduced aerody-
namic drag.
.Maintaining a safe following distance
behind other vehicles reduces unne-
cessary braking.
.Safely monitoring traffic to anticipate
changes in speed permits reduced
braking and smooth acceleration
changes.
.Select a gear range suitable to road
conditions.
5. Use cruise control.
.Using cruise control during highway
driving helps maintain a steady speed.
.Cruise control is particularly effective
in providing fuel savings when driving
on flat terrains.
6. Plan for the shortest route.
.Utilize a map or navigation system to
determine the best route to save time.
7. Avoid idling.
.Shutting off your engine when safe
for 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 cruising
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 more than
30 seconds of idling at start-up to
effectively circulate the engine oil
before driving.
.Your vehicle will reach its ideal oper-
ating temperature more quickly while
driving versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered parking
area or in the shade whenever possi-
ble.
.When entering a hot vehicle, opening
the windows will help to reduce the
inside temperature faster, resulting 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 engine
oil. (See “Engine oil and oil filter recom-
mendation” (P.10-6).)

If the belt is in poor condition or loose,
have it replaced or adjusted. It is recom-
mended you visit an INFINITI retailer for
this service.
2. Have the belts checked regularly for
condition and tension in accordance with
the maintenance schedule shown in the
“9. Maintenance and schedules” section.
WARNING
Be sure the engine and the ignition
switch are off and that the parking
brake is engaged securely.
CAUTION
Be sure to use the correct socket to
remove the spark plugs. An incorrect
socket can damage the spark plugs.

REPLACING SPARK PLUGS
If replacement is required, it is recommended
you visit an INFINITI retailer for this service.
Iridium-tipped spark plugs
It is not necessary to replace the iridium-
tipped spark plugs as frequently as the
conventional type spark plugs since they will
last much longer. Follow the maintenance
schedule shown in the “9. Maintenance and
schedules” section, but do not reuse them by
cleaning or regapping.
Always replace spark plugs with recom-
mended or equivalent ones.
SPARK PLUGS

WARNING
.Operating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops flame
if the engine backfires. If it is not
there, and the engine backfires, you
could be burned. Do not drive with
the air cleaner removed, and be care-
ful when working on the engine with
the air cleaner removed.
.Never pour fuel into the throttle body
or attempt to start the engine with
the air cleaner removed. Doing so
could result in serious injury.
The filter element should not be cleaned and
reused. Replace it according to the main-
tenance schedule shown in the “9. Main-
tenance and schedules” section. When
replacing the filter, wipe the inside of the
air cleaner housing and the cover with a
damp cloth.
When maintenance is required, it is recom-
mended you contact an INFINITI retailer for
servicing.
CLEANING
If your windshield is not clear after using the
windshield washer or if a wiper blade
chatters when running, wax or other materi-
al may be on the blade or windshield.
Clean the outside of the windshield with a
washer solution or a mild detergent. Your
windshield is clean if beads do not form
when rinsing with clear water.
Clean each blade by wiping it with a cloth
soaked in a washer solution or a mild
detergent. Then rinse the blade with clear
water. If your windshield is still not clear
after cleaning the blades and using the
wiper, replace the blades.
Worn windshield wiper blades can damage
the windshield and impair driver vision.
When a washer nozzle is clogged
If a washer nozzle is clogged or any
malfunction occurs, have it checked. It is
recommended you visit an INFINITI retailer
for this service. Do not attempt to clean the
nozzle using a needle or a pin. Doing so may
damage the nozzle.

Under some driving or climate conditions,
occasional brake squeak, squeal or other
noise may be heard. Occasional brake noise
during light to moderate stops is normal and
does not affect the function or performance
of the brake system.
Proper brake inspection intervals should be
followed.For additional information, see the
maintenance schedule shown in the “9.
Maintenance and schedules” section.

WARNING
Never use a fuse of a higher or lower
amperage rating than that specified on
the fuse box cover. This could damage
the electrical system or electronic con-
trol units or cause a fire.
If any electrical equipment does not operate,
check for an open fuse.
1. Be sure the ignition switch is placed in
the OFF or LOCK position and the
headlight switch is turned to OFF.
2. Open the engine hood.
3. Remove the fuse/fusible link holder
cover.
4. Remove the fuse with the fuse puller.

TIRE CHAINS
CAUTION
Tire chains/cables should not be in-
stalled on P255/40RF19,
P255/35R20, 255/35R20 and
275/30R20 tires. Doing so will cause
damage to the vehicle. If you plan to use
tire chains/cables, you should install
245/40RF19 run-flat tires or
245/40R19 non run-flat tires on your
vehicle.
Use of tire chains may be prohibited accord-
ing 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 sug-
gestions.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 component 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 damageyour vehicle. Use chain tensioners when
recommended 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 loading your vehicle
when using tire chains. In addition, drive at
a reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling
and performance may be adversely affected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Never install tire chains on a TEMPORARY
USE ONLY spare tire (if so equipped). Never
install tire chains on a punctured run-flat tire
(if so equipped), as this could damage your
vehicle.
Do not use tire chains on dry roads. Driving
with tire chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress.

CHANGING WHEELS AND TIRES
Tire rotation (models equipped with
same size tires on all wheels)
INFINITI recommends rotating the
tires at the specified interval shown
in the maintenance schedule. (See the
"9. Maintenance and schedules" sec-
tion. For tire replacing procedure, see
“Jacking up the vehicle and replacing
tires” (P.8-38).)
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.
