Removing the resonator
Remove the resonator*Aif necessary. Pull the
resonator upward to remove it. Install the
resonator securely after any inspection or
maintenance work is performed. 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 protection. The antifreeze solution
contains rust and corrosion inhibitors. Additional
engine cooling system additives are not neces-
sary.
WARNING
.
Never remove the radiator or cool-
ant reservoir cap when the engine is
hot. Wait until the engine and
radiator cool down. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
See precautions in “If your vehicle
overheats” (P.6-11) of this manual.
. The radiator is equipped with a
pressure type radiator cap. To pre-
vent engine damage, use only a
genuine NISSAN radiator cap.
CAUTION
.Never use any cooling system ad-
ditives such as radiator sealer. Ad- ditives may clog the cooling system
and cause damage to the engine,
transmission and/or cooling sys-
tem.
. When adding or replacing coolant,
be sure to use only Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) or equivalent. Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) is pre-diluted to provide
antifreeze protection to −348 F
(−378C) . If additional freeze protec-
tion is needed due to weather where
you operate your vehicle, add Gen-
uine NISSAN Long Life Antifreeze/
Coolant (blue) concentrate follow-
ing the directions on the container.
If an equivalent coolant other than
Genuine NISSAN Long Life Anti-
freeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s
instructions to maintain minimum
antifreeze protection to −348 F
(−378C) . The use of other types of
coolant solutions other than Genu-
ine 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. Mixing any other
type of coolant other than Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) , including Genuine
NISSAN Long Life Antifreeze/Cool-
ant (green) , or the use of non-
distilled water will reduce the life
expectancy of the factory-fill cool-
ant. Refer to the NISSAN Service
and Maintenance Guide for more
details.

CHECKING ENGINE COOLANT LEVEL
Check the coolant level in the reservoir when
the engine is cold. If the coolant level is below
the MIN level
*2, open the reservoir cap and
add coolant up to the MAX level
*1. If the
reservoir 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 up to the MAX level
*1.
Tighten the cap securely after adding engine
coolant.
If the cooling system frequently requires
coolant, have it checked by a NISSAN
dealer.
CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by a NISSAN dealer. The service
procedures can be found in the appropriate
NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
. To avoid the danger of being
scalded, never change the coolant
when the engine is hot.
. Never remove the radiator cap when
the engine 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 reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.

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 manufacturer 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
front wheels and not on the rear wheels.
Never install tire chains on a TEMPORARY USE
ONLY spare tire.
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.

every 7,500 miles (12,000 km) . (See “Flat
tire” (P.6-2) for tire replacing procedures.)
As soon as possible, tighten the wheel
nuts to the specified torque with a
torque wrench.Wheel nut tightening torque:80 ft-lb (108 N·m)
The wheel nuts must be kept tigh-
tened to the specification at all times. It is recommended that wheel nuts be
tightened to the specification at each
tire rotation interval.
WARNING
.
After rotating the tires, check
and adjust the tire pressure.
. Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.) .
. Do not include the spare tire or
any other small size spare tire in
the tire rotation.
