2003 INFINITI G35 coolant temperature

CHANGING ENGINE COOLANT O Major cooling system repairs should be
performed by your INFINITI retailer. The
service procedures can be found in the
appropriate INFINITI Service Manual. O Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING O To avoid being scalded, never change
the coolant when the engine is hot.
O Never remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
O Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
O Keep coolant out of reach of children
and pets.
1. Open radiator drain plug at the bottom of
radiator, and remove radiator filler cap.
O Be careful not to allow coolant to con-
tact drive belts.
O Waste coolant must be disposed of
properly. Check your local regulations.
2. Close the radiator drain plug securely after
the coolant is drained. 3. Fill the radiator slowly with the proper mix-
ture of anti-freeze solution and demineral-
ized water/distilled water. Fill the reservoir
tank up to the MAX level. Then install the
radiator filler cap.
4. Start the engine and warm it up until it
reaches normal operating temperature.
Then race the engine 2 or 3 times under no
load. Watch the engine coolant tempera-
ture gauge for signs of overheating.
5. Stop the engine. After it completely cools
down, refill the radiator up to the filler
opening. Fill the reservoir tank up to the
MAX level. Check the drain plug for any
sign of leakage.
6. Recheck the coolant level after the vehicle
has been driven for a day.SDI0114

Seat belts: Check that all parts of the seat belt
system (For example, buckles, anchors, ad-
justers and retractors) operate properly and
smoothly, and are installed securely. Check
the belt webbing for cuts, fraying, wear or
damage.
Accelerator pedal: Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort. Keep
the floor mat away from the pedal.
Clutch pedal*: Make sure the pedal operates
smoothly and check that it has the proper free
play.
Brakes: Check that the brakes do not pull the
vehicle to one side when applied.
Brake pedal*: Check the pedal for smooth
operation and make sure it has the proper
distance under it when depressed fully. Check
the brake booster function. Be sure to keep the
floor mat away from the pedal.
Parking brake*: Check that the lever has the
proper travel and confirm that your vehicle is
held securely on a fairly steep hill with only the
parking brake applied.
Automatic transmission P (Park) mecha-
nism: On a fairly steep hill check that your
vehicle is held securely with the selector lever in the P (Park) position without applying any
brakes.
Under the hood and vehicle The maintenance items listed here should be
checked periodically (For example, each time
you check the engine oil or refuel).
Windshield washer fluid*: Check that there
is adequate fluid in the tank.
Engine coolant level*: Check the coolant
level when the engine is cold.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure
the hoses have no cracks, deformation, dete-
rioration or loose connections.
Brake and clutch fluid level*: Make sure that
the brake and clutch fluid level is between the
MAX and MIN lines on the reservoir.
Battery*: Check the fluid level in each cell.
It should be between the MAX and MIN lines.
Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
Engine drive belts*: Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*: Check the level after park- ing the vehicle on a level spot and turning off
the engine. (Wait at least 10 minutes for the oil
to drain back into the oil pan.)
Power steering fluid level* and lines: Check
the level when the fluid is cold and the engine
is turned off. Check the lines for proper attach-
ment, leaks, cracks, etc.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the sound of
the exhaust seems unusual or there is a smell
of exhaust fumes, immediately locate the
trouble and correct it. See ªPrecautions when
starting and drivingº in the ª5. Starting and
drivingº section for exhaust gas (Carbon mon-
oxide).
Underbody: The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, being careful
to clean those areas where mud and dirt may
accumulate. For additional information, see
ªCleaning exteriorº in the ª7. Appearance and
careº section.
Fluid leaks: Check under the vehicle for fuel,
oil, water or other fluid leaks after the vehicle

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

If you believe that your vehicle has a defect
which could cause a crash or could cause
injury or death, you should immediately
inform the National Highway Traffic Safety
Administration
(NHTSA) in addition to no-
tifying INFINITI.
If
NHTSA receives similar complaints, it
may open an investigation, and if it finds
that a safety defect exists in a group of
vehicles, it may order a recall and remedy
campaign. However,
NHTSA cannot be-
come involved in individual problems be-
tween you, your retailer, or INFINITI.
To contact
NHTSA , you may call the Auto
Safety Hotline toll-free at 1-888-327-4236.
You may also write to:
NHTSA , U.S. De-
partment of Transportation, Washington,
D.C. 20590. You can also obtain other
information about motor vehicle safety from
the Hotline. You may notify INFINITI by contacting our
Consumer Affairs Department, toll-free, at
1-800-662-6200.
In Hawaii call (808) 836-0888. Due to legal requirements in some states/
areas, your vehicle may be required to be in
what is called the ªready conditionº for an
Inspection/Maintenance (I/M) test of the emis-
sion control system.
The vehicle is set to the ªready conditionº
when it is driven through certain driving pat-
terns. Usually, the ªready conditionº can be
obtained by ordinary usage of the vehicle.
If a powertrain system component is repaired
or the battery is disconnected, the vehicle may
be reset to a not ªready conditionº. Before
taking the I/M test, drive the vehicle through
the following pattern to set the vehicle to the
ready condition. If you cannot or do not want to
perform the driving pattern, an INFINITI re-
tailer can conduct it for you.
WARNING Always drive the vehicle in a safe and
prudent manner according to traffic con-
ditions, and obey all traffic laws.
1. Start the engine. Allow the engine to idle
until the engine coolant temperature gauge
needle points between the C and H (normal
operating temperature). 2. Accelerate the vehicle to 55 MPH (88
km/h), then quickly release the accelerator
pedal completely and keep it released for at
least 6 seconds.
3. Quickly depress the accelerator pedal for a
moment, then drive the vehicle at a speed
of 53 to 60 MPH (86 to 96 km/h) for at least
5 minutes.
4. Stop the vehicle. Leave the engine running.
5. Accelerate the vehicle to 35 MPH (55 km/h)
and maintain the speed for 20 seconds.
6. Repeat steps 4 and 5 at least 3 times.
7. Accelerate the vehicle to 55 MPH (88 km/h)
and maintain the speed for at least 3 min-
utes.
8. Stop the vehicle. Place the automatic trans-
mission selector lever in the ªPº or ªNº
position or the manual transmission shift
lever in the ªNº position.
9. Turn the engine off.
10.Repeat steps 1 through 8 at least one more
time.
If step 1 through 7 is interrupted, repeat the
preceding step. Any safe driving mode is ac-
ceptable between steps. Do not stop the en-
gine until step 7 is completed.REPORTING SAFETY DEFECTS
