ESP INFINITI QX 2011 Service Manual

Your new INFINITI has been designed to have
minimum maintenance requirements with long
service intervals to save you both time and
money. However, some day-to-day and regular
maintenance is essential to maintain your IN-
FINITI’s fine mechanical condition, as well as its
emission and engine performance.
It is the owner’s responsibility to make sure that
the scheduled maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the only one who
can ensure that your vehicle receives the proper
maintenance care. You are a vital link in the
maintenance chain.
SCHEDULED MAINTENANCE
For your convenience, both required and op-
tional scheduled maintenance items are de-
scribed and listed in your “INFINITI Service and
Maintenance Guide”. You must refer to that
guide to ensure that necessary maintenance is
performed on your INFINITI at regular intervals.
GENERAL MAINTENANCE
General maintenance includes those items
which should be checked during normal day-to-
day operation. They are essential for proper
vehicle operation. It is your responsibility to
perform these procedures regularly as pre-
scribed.
Performing general maintenance checks re-
quires minimal mechanical skill and only a few
general automotive tools.
These checks or inspections can be done by
yourself, a qualified technician or, if you prefer,
an INFINITI retailer.
WHERE TO GO FOR SERVICE
If maintenance service is required or your ve-
hicle appears to malfunction, have the systems
checked and serviced by an INFINITI retailer.
INFINITI technicians are well-trained specialists
and are kept up to date with the latest service
information through technical bulletins, service
tips, and in-retailership information systems.
They are completely qualified to work on
INFINITI vehiclesbeforework begins.
You can be confident that an INFINITI retailer’s
service department performs the best job to
meet the maintenance requirements on your
vehicle — in a reliable and economical way. During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or have an
INFINITI retailer do it promptly. In addition, you
should notify an INFINITI retailer if you think
that repairs are required.
When performing any checks or maintenance
work, see “MAINTENANCE PRECAUTIONS” later
in this section.

you
should first find out if the fuel available is
suitable for your vehicle’s engine.
Using fuel with too low an octane rating may
cause engine damage. All gasoline vehicles
must be operated with unleaded gasoline.
Therefore, avoid taking your vehicle to areas
where appropriate fuel is not available.
When transferring the registration of your ve-
hicle to another country, state, province or dis-
trict, it may be necessary to modify the vehicle
to meet local laws and regulations.
The laws and regulations for motor vehicle
emission control and safety standards vary
according to the country, state, province or
district; therefore, vehicle specifications may
differ.
When any vehicle is to be taken into another
country, state, province or district and regis-
tered, its modifications, transportation, and reg-
istration are the responsibility of the user.
INFINITI is not responsible for any inconvenience
that may result.

Temperature conditions can also affect towing.
For example, towing a heavy trailer in high
outside temperatures on graded roads can af-
fect engine performance and cause overheat-
ing. The transmission high fluid temperature
and engine protection mode, which helps re-
duce the chance of transmission and engine
damage, could activate and automatically de-
crease engine power. Vehicle speed may de-
crease under high load. Plan your trip carefully
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 collision. 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. See “IF
YOUR VEHICLE OVERHEATS” in the “6. In case of
emergency” section of this manual.
CAUTION
Vehicle damage resulting from improper tow-
ing procedures is not covered by INFINITI
warranties.
Tongue load
When using a weight carrying or a weight
distributing hitch, keep the tongue load be-
tween 10 to 15% of the total trailer load or use
the trailer tongue load specified by the trailer
manufacturer. The tongue load must be within
the maximum tongue load limits shown in the
following “Towing Load/Specification” chart. If
the tongue load becomes excessive, rearrange
cargo to allow for proper tongue load.

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 mea-
sured under controlled conditions on specified
government test surfaces of asphalt and con-
crete. A tire marked C may have poor traction
performance.
WARNING
The traction grade assigned to this tire is based
on straight-ahead braking traction tests, and
does not include acceleration, cornering, hy-
droplaning, or peak traction characteristics.
TEMPERATURE A, B AND C
The temperature grades A (the highest), B, and
C, representing the tire’s resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the ma-
terial of the tire to degenerate and reduce tire
life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A rep-
resent higher levels of performance on the
laboratory test wheel than the minimum re-
quired by law.
WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and not
overloaded. Excessive speed, under-inflation,
or excessive loading, either separately or in
combination, can cause heat build-up and pos-
sible tire failure.Your INFINITI is covered by the following emis-
sion warranties.
