CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine is cold. If the coolant level is below
the MIN level
B, add coolant to the MAX
level
A. 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 reser-
voir up to the MAX level
A. This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years.
Mixing any other type of coolant that is not
equivalent to Genuine NISSAN Long Life
Antifreeze/Coolant (blue), or the use of non-
distilled water will reduce the life expectancy
of the factory-fill coolant. For additional in-
formation, refer to the "Maintenance and
schedules" section of this manual.
If the cooling system frequently requires
coolant, have it checked. It is recommended
that you visit an INFINITI retailer for this
service.
For additional information on the location of
the engine coolant reservoir, refer to “Engine
compartment check locations” in this section.
CHANGING ENGINE COOLANT
An INFINITI retailer can change the engine
coolant. The service procedure can be found
in the 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 en-
gine is hot.
∙ Never remove the radiator or engine coolant reservoir 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 cool- ant. If skin contact is made, wash thor-
oughly 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.

Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which
may cause excessive fuel consumption or en-
gine damage. If any of the above symptoms
are encountered, have your vehicle checked.
It is recommended that you visit an INFINITI
retailer.
However, now and then you may notice light
spark knock for a short time while accelerat-
ing or driving up hills. This is not a cause for
concern, because you get the greatest fuel
benefit when there is light spark knock for a
short time under heavy engine load.
ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade,
quality and viscosity engine oil to ensure sat-
isfactory engine life and performance. For
additional information, refer to "Recom-
mended fluids/lubricants and capacities" in
this section. INFINITI recommends the use of
an energy conserving oil in order to improve
fuel economy.Select only engine oils that meet the Ameri-
can Petroleum Institute (API) certification or
International Lubricant Standardization and
Approval Committee (ILSAC) certification
and SAE viscosity standard. These oils have
the API certification mark on the front of the
container. Oils which do not have the speci-
fied quality label should not be used as they
could cause engine damage.
Oil additives
INFINITI does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.

10-6Technical and consumer information

Your new vehicle was designed to be used
primarily to carry passengers and cargo. Re-
member that towing a trailer places addi-
tional loads on your vehicle’s engine, drive
train, steering, braking and other systems.
An INFINITI Towing Guide (U.S. only) is avail-
able on the website atwww.InfinitiUSA.com.
This guide includes information on trailer
towing capability and the special equipment
required for proper towing.
MAXIMUM LOAD LIMITS
Maximum trailer loads
Never allow the total trailer load to exceed
the value specified in the following Towing
Load/Specification Chart found in this sec-
tion. The total trailer load equals trailer
weight plus its cargo weight.
∙ When towing a trailer load of 3,500 lbs.
(1,587 kg) or more, trailers with a brake
system MUST be used.
The maximum Gross Combined Weight Rat-
ing (GCWR) should not exceed the value
specified in the following Towing
Load/Specification Chart. The GCWR equals the combined weight of
the towing vehicle (including passengers and
cargo) plus the total trailer load. Towing
loads greater than these or using improper
towing equipment could adversely affect ve-
hicle handling, braking and performance.
The ability of your vehicle to tow a trailer is
not only related to the maximum trailer loads,
but also the places you plan to tow. Tow
weights appropriate for level highway driving
may have to be reduced for low traction situ-
ations (for example, on slippery boat ramps).
Temperature conditions can also affect tow-
ing. For example, towing a heavy trailer in
high outside temperatures on graded roadscan affect engine performance and cause
overheating. The engine protection mode,
which helps reduce the chance of engine
damage, could activate and automatically
decrease engine power. Vehicle speed may
decrease under high load. Plan your trip care-
fully to account for trailer and vehicle load,
weather and road conditions.
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced
speed may be lower than other traffic,
which could increase the chance of a colli-
sion. Be especially careful when driving. If
the vehicle cannot maintain a safe driving
speed, pull to the side of the road in a safe
area. Allow the engine to cool and return to
normal operation. For additional informa-
tion, refer to “If your vehicle overheats” in
the “In case of emergency” section of this
manual.
CAUTION
Vehicle damage resulting from improper
towing procedures is not covered by
INFINITI warranties.
