[Power Steering Malfunction See Operators
Manual]
In conjunction with this warning, steering as-
sistance will no longer be provided by the sys-
tem.
The effort required to steer the vehicle will
increase. This will be most noticeable at low
speed and when performing a tight turning
maneuver.
Check whether you are able to provide the ex-
tra effort required.

ELECTRIC POWER STEERING SYSTEM
5-86Starting and driving

WARNING
•Never rely solely on the Hill Start Assist
(HSA) system to prevent the vehicle from
moving backward on a hill. Always drive
carefully and attentively. Depress the brake
pedal when the vehicle is stopped on a
steep hill. Be especially careful when
stopped on a hill on frozen or muddy roads.
Failure to prevent the vehicle from rolling
backwards may result in a loss of control of
the vehicle and possible serious injury or
death.
•The Hill Start Assist system is not designed
to hold the vehicle at a standstill on a hill.
Depress the brake pedal when the vehicle is
stopped on a steep hill. Failure to do so may
cause the vehicle to roll backwards and may
result in a collision or serious personal in-
jury.
•The Hill Start Assist system may not pre-
vent the vehicle from rolling backwards on a
hill under all load or road conditions. Al-
ways be prepared to depress the brake
pedal to prevent the vehicle from rolling
backwards. Failure to do so may result in a
collision or serious personal injury.
•After a short time, hill start assist will no
longer brake your vehicle and it could roll
away There is a risk of an accident and in-
jury. Therefore, quickly move your foot from
the brake pedal to the accelerator pedal.
Never leave the vehicle when it is held by
hill start assist.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It
holds the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and
depress it before the vehicle begins to roll.
Hill start assist is not active if
•You are pulling away on a level road or a
downhill gradient.
•On vehicles with automatic transmission,
the transmission is in position N.
•The electric parking brake is applied.
•VDC is malfunctioning.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the
key hole, or use the INFINITI Intelligent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C), check the
antifreeze to assure proper winter protection. For
additional information, seeEngine cooling
systemin the8. Do-it-yourselfsection.
BATTERY
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For details, see
Batteryin the8. Do-it-yourselfsection of this
manual.
DRAINING OF ENGINE COOLANT
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, seeChanging engine

usual circumstances force you to drive so
slowly that your vehicle might become a
hazard to other traffic.
•Turn signals do not work when the hazard
warning flasher lights are on.
Some jurisdictions may prohibit the use of the
hazard warning flasher switch while driving.If you have a flat tire, follow the instructions in
this section.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
WARNING
•If the low tire pressure warning light illumi-
nates or a tire pressure-related warning is
displayed by the vehicle information dis-
play while driving, avoid sudden steering
maneuvers or abrupt braking, reduce ve-
hicle speed, pull off the road to a safe loca-
tion and stop the vehicle as soon as pos-
sible. Driving with under-inflated tires may
permanently damage the tires and increase
the likelihood of tire failure. Serious vehicle
damage could occur and may lead to an ac-
cident and could result in serious personal
injury. Check the tire pressure for all four
tires. Adjust the tire pressure to the recom-
mended COLD tire pressure shown on the
tire and loading information label to turn
the low tire pressure warning light OFF. If
you have a flat tire, replace it with a replace-
ment tire as soon as possible.

When performing any inspection or mainte-
nance work on your vehicle, always take care to
prevent serious accidental injury to yourself or
damage to the vehicle. The following are gen-
eral precautions which should be closely ob-
served.
WARNING
•Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from moving.
Press the P (Park) button.
•Be sure the ignition switch is in the OFF
position when performing any parts re-
placement or repairs.
•Do not work under the hood while the en-
gine is hot. Always turn off the engine and
wait until it cools down.
•If you must work with the engine running,
keep your hands, clothing, hair and tools
away from moving fans, belts and any other
moving parts.
•It is advisable to secure or remove any loose
clothing and any jewelry, such as rings,
watches, etc. before working on your ve-
hicle.
•If you must run the engine in an enclosedspace such as a garage, be sure there is
proper ventilation for exhaust gases to es-
cape.
•Never get under the vehicle while it is sup-
ported by a jack.
•Keep smoking materials, flame and sparks
away from fuel and the battery.
•Never connect or disconnect either the bat-
tery or any transistorized component con-
nector while the ignition switch is in the ON
position.
•On gasoline engine models with the Multi-
port Fuel Injection system, the fuel filter and
fuel lines should be serviced by an INFINITI
retailer or qualified workshop because the
fuel lines are under high pressure even
when the engine is turned off.
•Your vehicle is equipped with an automatic
engine cooling fan. It may come on at any
time without warning, even if the ignition
switch is in the OFF position and the engine
is not running. To avoid injury, always dis-
connect the negative battery cable before
working near the fan.
•Always wear eye protection whenever you
work on your vehicle.
•Never leave the engine or the transmission
related component harness connector dis-
connected while the ignition switch is in the
ON position.
•Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, engine coolant, and/or other vehicle flu-
ids can hurt the environment. Always con-
form to local regulations for disposal of ve-
hicle fluids.
This “ 8. Do-it-yourself” section provides in-
structions regarding only those items which are
relatively easy for an owner to perform.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could affect
your warranty coverage.If in doubt about any
servicing, it is recommended you have it done by
an INFINITI retailer.
