the driver's door opening, see "Tire and load-
ing information label". The low tire pressure
warning light does not automatically turn
off when the tire pressure is adjusted. After
the tire is inflated to the recommended pres-
sure, the vehicle must be driven at speeds
above 16 MPH (25 km/h) to activate the
TPMS and turn off the low tire pressure
warning light. Use a tire pressure gauge to
check the tire pressure.
The low tire pressure warning message ap-
pears each time the ignition switch is placed
in the ON position as long as the low tire
pressure warning light remains illuminated.
For additional information, see "Vehicle in-
formation display" later in this section and
"Tire Pressure Monitoring System (TPMS)".
TPMS malfunction:
If the TPMS is not functioning properly, the
low tire pressure warning light will flash for
approximately 1 minute when the ignition
switch is placed in the ON position. The light
will remain on after 1 minute. Have the sys-
tem checked. It is recommended that you visit
an INFINITI retailer for this service. The low
tire pressure warning does not appear if the
low tire pressure warning light illuminates to
indicate a TPMS malfunction.
For additional information, see "Tire Pressure
Monitoring System (TPMS)".WARNING
•Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufac-
turer for the possible influences before
use.
•If the light does not illuminate with the
ignition switch pushed ON, have the ve-
hicle checked. It is recommended you
visit an INFINITI retailer for this service.
•If the light illuminates while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle speed,
pull off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and in-
crease the likelihood of tire failure. Seri-
ous vehicle damage could occur and may
lead to an accident and could result in
serious personal injury or death. Check
the tire pressure for all four tires. Adjust
the tire pressure to the recommended
COLD tire pressure shown on the tire
placard, located in the driver's door
opening, to turn the low tire pressure
warning light off. If the light still illumi-
nates while driving after adjusting the
tire pressure, a tire may be flat. If youhave a flat tire, replace it with a replace-
ment tire as soon as possible.
•If a replacement tire is mounted or a
wheel is replaced without a TPMS sen-
sor tire pressure will not be indicated,
the TPMS will not function and the low
tire pressure warning light will flash for
approximately 1 minute. The light will
remain on after 1 minute. Have your ve-
hicle's tires replaced and/or TPMS sys-
tem reset as soon as possible. It is rec-
ommended you visit an INFINITI retailer
for these services.
•Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
CAUTION
•The TPMS is not a substitute for the
regular tire pressure check. Be sure to
check the tire pressure regularly.
•If the vehicle is being driven at speeds of
less than 16 MPH (25 km/h), the TPMS
may not operate correctly.
•Be sure to install the specified size of
tires to all four wheels correctly.

•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

•Keep your engine tuned up.
•Follow the recommended scheduled
maintenance.
•Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
•Keep all the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
•Use the recommended viscosity engine oil.
For additional information, see "Recom-
mended fluids/lubricants and capacities"
WARNING
•Do not drive beyond the performance
capability of the tires, even with 4WD
engaged. Accelerating quickly, sharp
steering maneuvers or sudden braking
may cause loss of control.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels.
•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 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to any
drive or reverse position with the engine
running. Doing so may result in drive-
train damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
•Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer
(such as the dynamometers used by
some states for emissions testing) or
similar equipment even if the other two
wheels are raised off the ground. Make
sure that you inform the test facility
personnel that your vehicle is equipped
with 4WD before it is placed on a dyna-
mometer. Using the wrong test equip-
ment may result in drivetrain damage or
unexpected vehicle movement which
could result in serious vehicle damage or
personal injury.
•When a wheel is off the ground due to an
uneven surface, do not spin the wheel
excessively.
INCREASING FUEL ECONOMY FOUR-WHEEL DRIVE (4WD) (IF
EQUIPPED)
5-86Starting and driving

brakes return to normal. Avoid driving the
vehicle at high speeds until the brakes func-
tion correctly.
Driving uphill
When starting on a steep gradient, it is some-
times difficult to operate the brake. Use the
parking brake to hold the vehicle. When ready
to start, make sure that the shift lever is in an
appropriate forward or reverse driving posi-
tion, release the parking brake while depress-
ing the accelerator pedal. If your vehicle has
an electric parking brake, this will automati-
cally release when you depress the accelera-
tor pedal (DCT models).
Driving downhill
The engine braking action is effective for
controlling the vehicle while descending hills.
A low gear position in the manual shift mode,
low enough to obtain sufficient engine brak-
ing, should be selected.
Parking brake break-in
Break in the parking brake shoes whenever the
stopping effect of the parking brake is weak-
ened or whenever the parking brake shoes
and/or drums/rotors are replaced, in order to
assure the best braking performance.
This procedure is described in the vehicle ser-
vice manual and can be performed by an
INFINITI retailer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot prevent
accidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking on
slippery surfaces. Remember that stopping
distances on slippery surfaces will be lon-
ger than on normal surfaces even with
ABS. Stopping distances may also be lon-
ger on rough, gravel or snow covered
roads, or if you are using tire chains. Al-
ways maintain a safe distance from the ve-
hicle in front of you. Ultimately, the driver
is responsible for safety.
Tire type and condition may also affect
braking effectiveness.
–When replacing tires, install the specified
size of tires on all four wheels.–When installing a replacement tire, make
sure that it is the proper size and type as
specified on the tire and loading informa-
tion label. (See "Wheels and Tires".)
–For detailed information, see "Wheels and
tires".
The Anti-lock Braking System (ABS) controls
the brakes so the wheels do not lock during
hard braking or when braking on slippery sur-
faces. The system detects the rotation speed
at each wheel and varies the brake fluid pres-
sure to prevent each wheel from locking and
sliding. By preventing each wheel from lock-
ing, the system helps the driver maintain
steering control and helps to minimize swerv-
ing and spinning on slippery surfaces.
Using system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady pres-
sure, but do not pump the brakes. The ABS will
operate to prevent the wheels from locking up.
Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.
Starting and driving5-91

•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 injury. Therefore, quickly move your
foot from the brake pedal to the accel-
erator 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 accel-
erator 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 be-
comes frozen, heat the key before inserting it
into the key hole, or use the INFINITI Intelli-
gent 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, see
"Engine cooling system".
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
"Battery" 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, see "Changing engine
coolant" of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced in
snowy and icy conditions. If you operate
your vehicle on snowy or icy roads,
INFINITI recommends the use of MUD &
SNOW or ALL SEASON TIRES on all four
wheels. It is recommended that you visit
an INFINITI retailer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, stud-
ded tires may be used. However, some
U.S. states and Canadian provinces pro-
hibit their use. Check local, state and pro-
vincial laws before installing studded tires.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow tires.
COLD WEATHER DRIVING
5-96Starting and driving

3. Tire chains may be used if desired. Make
sure they are the proper size for the tires
on your vehicle and are installed according
to the chain manufacturer’s instructions.
Use chain tensioners when recommended
by the tire chain manufacturer to ensure a
tight fit. Loose end links of the tire chains
must be secured or removed to prevent
the possibility of whipping action damage
to the fenders or underbody. In addition,
drive at a reduced speed, otherwise, your
vehicle may be damaged and/or vehicle
handling and performance may be ad-
versely affected.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during the winter:
•A scraper and stiff-bristled brush to re-
move ice and snow from the windows.
•A sturdy, flat board to be placed under the
jack to give it firm support.
•A shovel to dig the vehicle out of snow-
drifts.
•Extra washer fluid to refill the windshield
washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
•Wet ice (32°F, 0°C and freezing rain),
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” under
these conditions. Try to avoid driving on
wet ice until the road is salted or sanded.
•Whatever the condition, drive with cau-
tion. Accelerate and slow down with
care. If accelerating or downshifting too
fast, the drive wheels will lose even more
traction.
•Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
•Allow greater following distances on
slippery roads.
•Watch for slippery spots (glare ice).
These may appear on an otherwise clear
road in shaded areas. If a patch of ice is
seen ahead, brake before reaching it. Try
not to brake while on the ice, and avoid
any sudden steering maneuvers.
•Do not use cruise control on slippery
roads.
•Snow can trap dangerous exhaust gas
under your vehicle. Keep snow clear of
the exhaust pipe and from around your
vehicle.
Starting and driving5-97

In addition to the vehicle load, the driving
distance possible depends upon:
•Vehicle speed.
•Road condition.
•Outside temperature.
The driving distance possible in run-flat mode
may be reduced by extreme driving
conditions/maneuvers, or it can be increased
through a moderate style of driving.
The driving distance possible in run-flat mode
is counted from the moment the tire pressure
loss warning appears in the vehicle informa-
tion display.
You must not exceed a maximum speed of
50 MPH (80 km/h).
When replacing one or all tires, observe the
following specifications for your vehicle's tires:
•Size
•Type
•Run-flat mark
If a tire has gone flat and cannot be replaced
with a run flat tire, a standard tire may be
used as a temporary measure. Make sure that
you use the proper size and type (summer or
winter tire).
WARNING
Do not exceed the stated maximum speed.
Avoid abrupt steering and driving maneu-
vers, and driving over obstacles (curbs, pot
holes, off road). This applies in particular to
a laden vehicle.
Stop driving in emergency mode if:
•You hear banging noises.
•The vehicle starts to shake.
•You see smoke and smell rubber.
•VDC is intervening constantly.
•There are tears in the sidewalls of the
tire.
After driving in emergency mode, have the
wheel rims checked with regard to their
further use. It is recommended you visit an
INFINITI retailer for this service. The faulty
tire must be replaced.
REMOVING AND FITTING
WHEELS
NOTE
A spare wheel is not provided with your ve-
hicle.
Blocking the wheels
WARNING
Make sure to block the appropriate wheel
to prevent the vehicle from moving, which
may cause personal injury.
Place suitable blocks
1in front of and be-
hind the wheel diagonally opposite the flat
tire
