•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"
in the "10. Technical information" section
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.

Starting and driving5-87
CAUTION
Never tow the vehicle with one axle raised.
This may damage the differential. Damage
of this sort is not covered by the warranty.
All wheels must be fully raised (see "Four-
Wheel Drive (4WD) models" in the "6. In
case of emergency" section)
4WD, together with VDC, improves the trac-
tion of your vehicle whenever a drive wheel
spins due to insufficient grip.
If you fail to adapt your driving style, 4WD
can neither reduce the risk of an accident nor
override the laws of physics. 4WD cannot
take account of road, weather, and traffic
conditions. 4WD is only an aid. You are re-
sponsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time, and for staying in lane.
If a drive wheel spins due to insufficient grip
•When pulling away, only depress the ac-
celerator pedal as far as is necessary.
•Accelerate less when driving.
NOTE
In wintry driving conditions, the maximum
effectiveness of 4WD can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.
WARNING
•Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
•Safe parking procedures require that
both the parking brake be applied and
the P (Park) position engaged. Failure to
do so could cause the vehicle to move
unexpectedly or roll away and result in
an accident.
•When parking the vehicle, make sure the
P (Park) position is engaged. The shift
lever cannot be moved out of the P
(Park) position without depressing the
brake pedal.
•Never leave the engine running while the
vehicle is unattended.
•Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls or move the
vehicle. Unattended children could be-
come involved in serious accidents.
•To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not leave
children, people who require the assis-
tance of others, or pets unattended in your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm
day can quickly become high enough to
cause a significant risk of injury or death
to people and pets.
CAUTION
Always secure the vehicle correctly against
rolling away. Otherwise, the vehicle or its
drive train could be damaged.
To ensure that the vehicle is secured against
rolling away unintentionally:
•The electric parking brake must be applied.
•The transmission must be in position P
(Park) and the transmission position dis-
play must show P in the vehicle informa-
tion display.
•The key must be removed from the ignition
switch.
•On uphill or downhill gradients, the front
wheels must be turned towards the curb.

Visit an INFINITI retailer and seek advice
NOTE
You can obtain information about trickle
chargers from an INFINITI retailer. The electric power steering system is de-
signed to reduce the driver effort required to
steer the vehicle.
WARNING
If during operation a fault is detected the
following message will be displayed in the
vehicle information display along with an
audible warning tone.
[Power Steering Malfunction See Opera-
tors Manual]
In conjunction with this warning, steering
assistance will no longer be provided by the
system.
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
extra effort required.
If you are able to steer safely: Carefully
drive on to an INFINITI retailer.
If you are unable to steer safely: Do NOT
drive on. It is recommended you contact
the nearest INFINITI retailer for
assistance.
CAUTION
•If wheels or tires other than INFINITI
recommended ones are used, the power
steering system may not operate prop-
erly and the [Power Steering Malfunc-
tion See Operators Manual] warning
may appear in the vehicle information
display.
•Do not modify the vehicle's suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not INFINITI
recommended for your vehicle or are ex-
tremely deteriorated, the power steer-
ing system may not operate properly
and the [Power Steering Malfunction

5-90Starting and driving
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
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced, in
order to assure the best braking perfor-
mance.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" in the
"9. Maintenance and Schedules" section.)
– For detailed information, see "Wheels and
tires" in the "8. Do-it-yourself" section.
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
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels from
locking up. Steer the vehicle to avoid ob-
stacles.
WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.

The hazard warning flasher switch1oper-
ates regardless of the ignition switch position
except when the battery is discharged.
The hazard warning flasher is used to warn
other drivers when you have to stop or park
under emergency conditions.
When the hazard warning flasher switch is
pushed, all turn signal lights will flash. To turn
off the hazard warning flasher, push the haz-
ard warning switch again.
WARNING
•If stopping for an emergency, be sure to
move the vehicle well off the road.
•Do not use the hazard warning flashers
while moving on the highway unless un-
usual circumstances force you to drive so slowly that your vehicle might be-
come a hazard to other traffic.
•Turn signals do not work when the haz-
ard 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 il-
luminates or a tire pressure-related
warning is displayed by the vehicle in-
formation display 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 increase the likeli-
hood of tire failure. Serious vehicle dam-
age could occur and may lead to an acci-
dent and could result in serious personal
injury. Check the tire pressure for all
four tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the tire and loading informa-
tion label to turn the low tire pressure
warning light OFF. If you have a flat tire,
replace it with a replacement tire as
soon as possible.

Two-Wheel Drive (FWD) models
CAUTION
NEVER tow automatic transmission (DCT)
models with the front wheels on the
ground or with all four wheels on the
ground (forwards or backwards), as this
may cause serious and expensive damage
to the transmission. If it is necessary to tow
the vehicle with the rear wheels raised, al-
ways use towing dollies under the front
wheels.
Four-Wheel Drive (4WD) models
INFINITI recommends that towing dollies be
used under the front or rear wheels when
towing your vehicle or the vehicle be placed
on a flatbed tow truck as illustrated.
CAUTION
Never tow 4WD models with any of the
wheels on the ground. Doing so will cause
serious and expensive damage to the
drivetrain.
Vehicle recovery (freeing a stuck

WARNING
To avoid vehicle damage, serious personal
injury or death when recovering a stuck ve-
hicle:
•Contact a professional towing service to
recover the vehicle if you have any ques-
tions regarding the recovery procedure.
•Tow chains or cables must be attached
only to main structural members of the
vehicle.
•Do not use the vehicle tie downs to tow
or free a stuck vehicle.
•Only use devices specifically designed
for vehicle recovery and follow the
manufacturer's instructions.
•Always pull the recovery device straight
out from the front of the vehicle. Never
pull at an angle.
•Route recovery devices so they do not
touch any part of the vehicle except the
attachment point.

information.)
2 Three-digit number (215): This number gives the width in millimeters of the tire
from sidewall edge to sidewall edge.
3 Two-digit number (60): This number, known as the aspect ratio, gives the tire’s
ratio of height to width.
4 R: The “R” stands for radial.
5 Two-digit number (16): This number is the wheel or rim diameter in inches. 6 Two- or three-digit number (94): This
number is the tire’s load index. It is a mea-
surement of how much weight each tire
can support. You may not find this infor-
mation on all tires because it is not re-
quired by law.

All season tires
INFINITI specifies all season tires on some
models to provide good performance all year,
including snowy and icy road conditions. All
season tires are identified by ALL SEASON
and/or M&S on the tire sidewall. Snow tires
have better snow traction than all season
tires and may be more appropriate in some
areas.
Summer tires
INFINITI specifies summer tires on some
models to provide superior performance on
dry roads. Summer tire performance is sub-
stantially reduced in snow and ice. Summer
tires do not have the tire traction rating M&S
on the tire sidewall.
If you plan to operate your vehicle in snowy or
icy conditions, INFINITI recommends the use
of snow or all season tires on all four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating
to the original equipment tires. If you do not,
it can adversely affect the safety and han-
dling of your vehicle.Generally, snow tires have lower speed rat-
ings than factory equipped tires and may not
match the potential maximum vehicle speed.
Never exceed the maximum speed rating of
the tire. If you install snow tires, they must be
the same size, brand, construction and tread
pattern on all four wheels.
For additional traction on icy roads, studded
tires may be used. However, some U.S. states
and Canadian provinces prohibit their use.
Check local, state and provincial laws before
installing studded tires. Skid and traction ca-
pabilities of studded snow tires on wet or dry
surfaces may be poorer than that of non-
studded snow tires.
Four-Wheel Drive (4WD) models
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked and
corrected as necessary. It is recommended
that you visit an INFINITI retailer.
TIRE CHAINS
CAUTION
Tire chains/cables should not be installed
on 235/45 R19 or 235/50 R18 size tires.
Installation of the tire chains/cables on
235/45 R19 or 235/50 R18 size tires will
cause damage to the vehicle. If you plan to
use tire chains/cables, you should install
215/60 R17 size tires on your vehicle.
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure that they are of proper size
for the tires on your vehicle and are installed
according to the chain manufacturer’s in-
structions.
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. If possible, avoid fully loading
your vehicle when using tire chains. In addi-
tion, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or vehicle
handling and performance may be adversely
affected.
Tire chains must be installed only on the
front wheels and not on the rear wheels.
