WARNING
•The exhaust gas and the exhaust system
are very hot. Keep people, animals and
flammable materials away from the ex-
haust system components.
•Do not stop or park the vehicle over
flammable materials such as dry grass,
wastepaper or rags. They may ignite
and cause a fire.
CAUTION
•Do not use leaded gasoline. (See "Rec-
ommended fluids/lubricants and ca-
pacities".) Deposits from leaded gaso-
line seriously reduce the ability of the
three-way catalyst to help reduce ex-
haust pollutants and/or damage the
three-way catalyst.
•Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems may cause overrich
fuel to flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if noticeable
loss of performance or other unusual op-
erating conditions are detected. Have
the vehicle inspected promptly. It is rec-ommended you visit an INFINITI retailer
for this service.
•Avoid driving with an extremely low fuel
level. Running out of fuel could cause the
engine to misfire, damaging the three-
way catalyst.
•Do not race the engine while warming it
up.
•Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if present),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label.
(If your vehicle has tires of a different size
than the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of yourtires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your tires
as soon as possible, and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the
system detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illumi-
nated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
Starting and driving5-3

•Always use tires of the same type, size,
brand, construction (bias, bias-belted,
or radial), and tread pattern on all four
wheels. Install tire chains on the front
wheels when driving on slippery roads
and drive carefully.
•Be sure to check the brakes immediately
after driving in mud or water. .
•Avoid parking your vehicle on steep hills.
If you get out of the vehicle and it rolls
forward, backward or sideways, you
could be injured.
•Whenever you drive off-road through
sand, mud or water as deep as the wheel
hub, more frequent maintenance may be
required. For additional information, re-
fer to "Maintenance schedules".
ALL-WHEEL DRIVE (AWD)
DRIVING SAFETY PRECAUTIONS
(IF SO EQUIPPED)
WARNING
•Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Install tire chains on the front
wheels when driving on slippery roads
and drive carefully.
•This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
•For AWD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to any
D (Drive) or R (Reverse) position with
the engine running. Doing so may result
in drivetrain damage or unexpected ve-
hicle movement which could result in se-
rious vehicle damage or personal injury
•Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer, (such as the dynamometers
used by some states for emissions test-
ing), or similar equipment even if the
other two wheels are raised off the
ground. Make sure you inform test facil-
ity personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong
test equipment may result in drivetrain
damage or unexpected vehicle move-
ment which could result in serious ve-
hicle damage or personal injury.
•When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
5-12Starting and driving

START3
The engine starter activates and the engine
will start. As soon as the engine has started,
release the key immediately. It will return to
the ON position.
NOTE
For vehicles fitted with Idle Stop/Start Sys-
tem:
When the engine is automatically stopped
by the Idle Stop/Start System the ignition
switch can still be operated as usual.
At the end of a journey turn the ignition OFF
to avoid a discharged battery. The Idle
Stop/Start System does not automatically
turn ignition off.
Vehicles with Intelligent Key are equipped with
keys featuring an integrated Intelligent Key
function and in some cases a detachable push-
button ignition switch (Start/Stop button).
A check which periodically establishes a radio
connection between the vehicle and the key
determines whether a valid key is in the ve-
hicle. This occurs, for example, when starting
the engine.
When you insert the push-button ignition
switch into the ignition lock, the system needs
approximately two seconds recognition time.
You can then use the push-button ignition
switch.
WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in
an emergency. (The engine will stop when
the ignition switch is pressed 3 consecutive
times in quick succession or the ignition
switch is pushed and held for more than 2
seconds.) If the engine stops while the ve-
hicle is being driven, this could lead to a
crash and serious injury.
Before operating the push-button ignition
switch:
•Select P (Park).Pressing the Start/Stop button several times
in succession corresponds to the different
key positions in the ignition lock. Prerequisite
for this is that:
•You do not depress the brake pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
To start the vehicle without actively using the
key:
•The push-button ignition switch must be
inserted in the ignition lock.
•The key must be in the vehicle.
•The vehicle must not be locked with the
key or Intelligent Key (see "Keys").
Do not keep the Intelligent Key:
•With electronic devices, for example a mo-
bile phone or another key.
•With metallic objects, for example coins or
metal film.
•Inside metallic objects, for example a metal
case.
This can affect the functionality of the Intel-
ligent Key.
