2003 INFINITI G35 engine overheat

after using oxygenate-blend fuels, immediately
change to a non-oxygenate fuel or a fuel with
a low blend of MTBE.
Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.
Aftermarket fuel additives INFINITI does not recommend the use of any
fuel additives (i.e. fuel injector cleaner, octane
booster, intake valve deposit removers, etc.)
which are sold commercially. Many of these
additives intended for gum, varnish or deposit
removal may contain active solvent or similar
ingredients that can be harmful to the fuel
system and engine.
Octane rating tips In most parts of North America, you should use
unleaded gasoline with an octane rating of at
least 87 or 91 AKI (Anti-Knock Index) number.
However, you may use unleaded gasoline with
an octane rating as low as 85 AKI number in
these high altitude areas [over 4,000 ft (1,219
m)] such as: Colorado, Montana, New Mexico,
Utah, Wyoming, northeastern Nevada, south-
ern Idaho, western South Dakota, western
Nebraska, and that part of Texas which is
directly south of New Mexico. Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on level
roads, have your dealer correct the condi-
tion. Failure to correct the condition is
misuse of the vehicle, for which INFINITI is
not responsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may
cause excessive fuel consumption or damage
to the engine. If any of the above symptoms
are encountered, have your vehicle checked at
an INFINITI retailer or other competent service
facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.

condition; check for improper tongue load,
overload, worn suspension or other pos-
sible causes of either condition.
O Always secure items in the trailer to prevent
load shifts while driving.
O Be certain your rear view mirrors conform to
all federal, state or local regulations. If not,
install any mirrors required for towing be-
fore driving the vehicle.
Trailer towing tips In order to gain skill and an understanding of
the vehicle's behavior, you should practice
turning, stopping and backing up in an area
which is free from traffic. Steering stability, and
braking performance will be somewhat differ-
ent than under normal driving conditions.
O Always secure items in the trailer to prevent
load shift while driving.
O Avoid abrupt starts, acceleration or stops.
O Avoid sharp turns or lane changes.
O Always drive your vehicle at a moderate
speed.
O Always block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if you
must do so, and if your vehicle is equipped with automatic transmission, first apply the
parking brake and block the wheels, and
then move the transmission selector lever
into the P (Park) position. If you move the
selector lever to the P (Park) position be-
fore blocking the wheels and applying the
parking brake, the transmission may be
damaged.
O When going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending on a long grade, down-
shift the transmission to a lower gear and
reduce speed to reduce chances of engine
overloading and/or overheating.
O If the engine coolant rises to an extremely
high temperature when the air conditioning
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by
opening the windows, switching the fan
control to high and setting the temperature
control to the HOT position.
O Trailer towing consumes more fuel than
normal circumstances.
O Avoid towing a trailer for the first 500 miles
(800 km).
O Have your vehicle serviced more often than
at intervals specified in the recommended
maintenance schedule. O When making a turn, your trailer wheels will
be closer to the inside of the turn than your
vehicle wheels. To compensate for this,
make a larger than normal turning radius
during the turn.
O Crosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly
causing vehicle sway. When being passed
by larger vehicles, be prepared for possible
changes in crosswinds that could affect
vehicle handling. If swaying does occur,
firmly grip the steering wheel, steer straight
ahead, and immediately (but gradually) re-
duce vehicle speed. This combination will
help stabilize the vehicle. Never increase
speed.
O Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember the length of the trailer
must also pass the other vehicle before you
can safely change lanes.
O To maintain engine braking efficiency and
electrical charging performance, do not use
sixth gear (manual transmission) or fifth
position (automatic transmission).
O Avoid holding the brake pedal down too
long or too frequently such as on long
down-hill sections of road. This could cause

the brakes to overheat, resulting in reduced
braking efficiency. Shift down and use en-
gine braking.
When towing a trailer, change transmission
oil more frequently.
See ªPeriodic maintenance schedulesº in
the ª9. Maintenanceº section. Shift down
and use engine braking. DOT (Department Of Transportation) Quality
Grades: All passenger car tires must conform
to federal safety requirements in addition to
these grades.
Quality grades can be found where applicable
on the tire sidewall between tread shoulder
and maximum section width. For example:
Treadwear 200 Traction AA Temperature A
Treadwear Treadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified government
test courses. For example, a tire graded 150
would wear one and a half (1-1/2) times as well
on the government course as a tire graded
100. However, relative tire performance de-
pends on actual driving conditions, and may
vary significantly from the norm due to varia-
tions in driving habits, service practices and
differences in road characteristics and climate.
Traction AA, A, B and C The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades represent
the tire's ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of asphalt and concrete. A tire marked C may have poor
traction performance.
WARNING The traction grade assigned to your ve-
hicle tires is based on straight-ahead
braking traction tests, and does not in-
clude acceleration, cornering, hydro-
planing, or peak traction characteristics.
Temperature A, B and C Temperature grades are A (the highest), B,
and C. They represent a tire's resistance to
heat build-up, and its ability to dissipate heat
when tested under controlled conditions on a
specified indoor laboratory test wheel. Sus-
tained high temperature can cause tire mate-
rial to degenerate, reducing tire life. Excessive
temperatures can lead to sudden tire failure.
Grade C corresponds to a performance level
which all passenger car tires must meet under
the Federal Motor Vehicle Safety Standard No.
109. Grades A and B represent higher levels of
performance on laboratory test wheels than
the minimum required by law.UNIFORM TIRE QUALITY
