CAUTION
Do not keep the starter motor engaged for more
than 10 seconds. If the engine does not start
right away, push the ignition switch to the OFF
position and wait 10 seconds before trying
again.
9. After starting your engine, carefully dis-connect the negative cable and then the
positive cable (
4→3→2→1).
10. Replace the vent caps (if so equipped). Be sure to dispose of the cloth used to
cover the vent holes as it may be con-
taminated with corrosive acid.
Do not attempt to start the engine by pushing.
CAUTION
●Automatic transmission models cannot be
push-started or tow-started. Attempting to
do so may cause transmission damage.
● Three way catalyst equipped models should
not be started by pushing since the three
way catalyst may be damaged.
● Never try to start the vehicle by towing it;
when the engine starts, the forward surge
could cause the vehicle to collide with the
tow vehicle.
If needed, Roadside Assistance is available.
Please see your Warranty Information Booklet
or Roadside Assistance I.D. Card for the toll-free
number to call (U.S.) or Warranty & Roadside
Assistance Information Booklet (Canada).
CAUTION
● Do not continue to drive if your vehicle over-
heats. Doing so could cause engine damage
or a vehicle fire.
● To avoid the danger of being scalded, never
remove the radiator cap while the engine is
still hot. When the radiator cap is removed,
pressurized hot water will spurt out, possi-
bly causing serious injury.
● Do not open the hood if steam is coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading), or
if you feel a lack of engine power, detect
abnormal noise, etc., take the following steps:
1. Move the vehicle safely off the road, apply the parking brake.
2. Automatic Transmission model:
Move the selector lever to the P (Park)
position.
Manual Transmission model:
Move the shift lever to the N (Neutral) posi-
tion.
Do not stop the engine.

3. Turn off the air conditioner. Open all thewindows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed.
4. If engine overheating is caused by climb- ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.
5. Get out of the vehicle. Look and listen for steam or coolant escaping from the radia-
tor before opening the hood. (If steam or
coolant is escaping, turn off the engine.)
Do not open the hood further until no
steam or coolant can be seen.
6. Open the engine hood.
WARNING
If steam or water is coming from the engine,
stand clear to prevent getting burned.
7. Visually check the drive belt for damage or looseness. Also check if the cooling fan
is running. The radiator hoses and radia-
tor should not leak water. If coolant is
leaking or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair, jewelry
or clothing to come into contact with, or get
caught in, engine belts or the engine cooling
fan. The engine cooling fan can start at any
time.
8. After the engine cools down, check the coolant level in the reservoir with the
engine running. Add coolant to the reser-
voir if necessary. Have your vehicle re-
paired at the nearest INFINITI retailer.
If needed, Roadside Assistance is available.
Please see your Warranty Information Booklet
or Roadside Assistance I.D. Card for the toll-free
number to call (U.S.) or Warranty & Roadside
Assistance Information Booklet (Canada). When towing your vehicle, all State (Provincial
in Canada) and local regulations for towing
must be followed. Incorrect towing equipment
could damage your vehicle. Towing instructions
are available from an INFINITI retailer. Local
service operators are familiar with the appli-
cable laws and procedures for towing. To assure
proper towing and to prevent accidental dam-
age to your vehicle, INFINITI recommends that
you have a service operator tow your vehicle. It
is advisable to have the service operator care-
fully read the following precautions.WARNING
●
Never ride in a vehicle that is being towed.
● Never get under your vehicle after it has been
lifted by a tow truck.
CAUTION
● When towing, make sure that the transmis-
sion, axles, steering system and drivetrain
are in working condition. If any unit is dam-
aged, dollies must be used.
● Always attach safety chains before towing.

The engine cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine NISSAN
Long Life Antifreeze/Coolant (blue) and 50% water
to provide year-round anti-freeze and coolant pro-
tection. The antifreeze solution contains rust and
corrosion inhibitors. Additional engine cooling
system additives are not necessary.
WARNING
●Never remove the radiator or coolant reservoir
cap when the engine is hot. Wait until the
engine and radiator cool down. Serious burns
could be caused by high pressure fluid escap-
ing from the radiator. See precautions in “IF
YOUR VEHICLE OVERHEATS” in the “6. In case
of emergency” section of this manual.
● The radiator is equipped with a pressure
type radiator cap. To prevent engine dam-
age, use only a genuine NISSAN radiator cap.
CAUTION
●When adding or replacing coolant, be sure to
use only Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent. Genu-
ine NISSAN Long Life Antifreeze/Coolant (blue)
is pre-diluted to provide antifreeze protection
to 34°F (37°C). If additional freeze protec-
tion is needed due to weather where you oper-
ate your vehicle, add Genuine NISSAN Long
Life Antifreeze/Coolant (blue) concentrate fol-
lowing the directions on the container. If an
equivalent coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue) is used,
follow the coolant manufacturer’s instructions
to maintain minimum antifreeze protection to
34°F (37°C). The use of other types of cool-
ant solutions other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or equivalent
may damage the engine cooling system.
●The life expectancy of the factory-fill coolant
is 105,000 miles (168,000 km) or 7 years. Mix-
ing any other type of coolant other than Genu-
ine NISSAN Long Life Antifreeze/Coolant
(blue), including Genuine NISSAN Long Life
Antifreeze/Coolant (green), or the use of non-
distilled water will reduce the life expectancy
of the factory-fill coolant. Refer to the INFINITI
Service and Maintenance Guide for more
details.
CHECKING ENGINE COOLANT LEVEL
Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below the MIN level
2, open the reservoir tank
cap and add coolant up to the MAX level
1.If
the reservoir tank is empty, check the coolant
level in the radiator when the engine is cold. If
there is insufficient coolant in the radiator, fill
the radiator with coolant up to the filler opening
and also add it to the reservoir tank up to the
MAX level
1.
Tighten the cap securely after adding engine
coolant.
If the cooling system frequently requires cool-
ant, have it checked by an INFINITI retailer.

CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by an INFINITI retailer. The service pro-
cedures can be found in the appropriate INFINITI
Service Manual.
Improper servicing can result in reduced heater
performance and engine overheating.
WARNING
●To avoid the danger of being scalded, never
change the coolant when the engine is hot.
● Never remove the radiator cap when the en-
gine is hot. Serious burns could be caused by
high pressure fluid escaping from the
radiator.
● Avoid direct skin contact with used coolant.
If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as
possible.
● Keep coolant out of the reach of children and
pets. Engine coolant must be disposed of properly.
Check your local regulations.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and
apply the parking brake.
2. Run the engine until it reaches operating temperature.
3. Turn off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way.
5. Remove the dipstick again and check the oil level. It should be within the range
1.
If the oil level is below
2, remove the oil
filler cap and pour recommended oil
through the opening. Do not overfill
