tions of the vehicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pressure.
Losing control of the vehicle may cause a
collision and result in personal injury.
.The vehicle generally moves or pulls in
the direction of the flat tire.
. Do not rapidly apply the brakes.
. Do not rapidly release the accelerator
pedal.
. Do not rapidly turn the steering wheel.
1. Remain calm and do not overreact.
2. Maintain a firm grip on the steering
wheel with both hands and try to hold a
straight course.
3. When appropriate, slowly release the accelerator pedal to gradually slow the
vehicle.
4. Gradually steer the vehicle to a safe location off the road and away from
traffic if possible. 5. Lightly apply the brake pedal to gradu-
ally stop the vehicle.
6. Turn on the hazard warning flashers and either contact a roadside emer-
gency service to change the tire or see
“Changing a flat tire” in the“6. In case
of emergency” section of this Owner’s
Manual.
DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alcohol or
drugs. Alcohol in the bloodstream reduces
coordination, delays reaction time and im-
pairs judgement. Driving after drinking
alcohol increases the likelihood of being
involved in an accident injuring yourself and
others. Additionally, if you are injured in an
accident, alcohol can increase the severity
of the injury.
INFINITI is committed to safe driving.
However, you must choose not to drive
under the influence of alcohol. Every year
thousands of people are injured or killed in
alcohol-related accidents. Although the local laws vary on what is considered to
be legally intoxicated, the fact is that
alcohol affects all people differently and
most people underestimate the effects of
alcohol.
Remember, drinking and driving don’t mix!
And that is true for drugs, too (over-the-
counter, prescription, and illegal drugs).
Don’t drive if your ability to operate your
vehicle is impaired by alcohol, drugs, or
some other physical condition.
DRIVING SAFETY PRECAUTIONS
Your INFINITI is designed for both normal
and off-road use. However, avoid driving in
deep water or mud as your INFINITI is
mainly designed for leisure use, unlike a
conventional off-road vehicle.
Remember that Two-Wheel Drive (2WD)
models are less capable than Four-Wheel
Drive (4WD) models for rough road driving
and extrication when stuck in deep snow,
mud, or the like.
Please observe the following precautions:
Starting and driving5-9

states for emissions testing), or similar
equipment even if the other two wheels
are raised off the ground. Make sure you
inform test facility personnel that your
vehicle is equipped with 4WD before it is
placed on a dynamometer. Using the
wrong test equipment may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury (4WD
models).
. When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
. Accelerating quickly, sharp steering
maneuvers or sudden braking may cause
loss of control.
. If at all possible, avoid sharp turning
maneuvers, particularly at high speeds.
Your vehicle has a higher center of
gravity than a conventional passenger
car. The vehicle is not designed for
cornering at the same speeds as con-
ventional passenger cars. Failure to
operate this vehicle correctly could
result in loss of control and/or a rollover
accident.
. 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 rear
wheels when driving on slippery roads
and drive carefully.
. Be sure to check the brakes immediately
after driving in mud or water. See “Brake
system” later in this section for wet
brakes.
. 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. See the maintenance
information in the “INFINITI Service and
Maintenance Guide”.
. Spinning the rear wheels on slippery
surfaces may cause the 4WD warning
light to flash. The 4WD system may also
automatically switch from the 4WD
mode to the 2WD mode. This could
reduce traction. Be especially careful
when towing a trailer (4WD models).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 pushed 3 consecutive
times or the ignition switch is pushed and
held for more than 2 seconds.) If the engine
stops while the vehicle is being driven, this
could lead to a crash and serious injury.
Before operating the push-button ignition
switch, be sure to move the shift lever to
the P (Park) position.
Starting and driving5-11
PUSH-BUTTON IGNITION SWITCH

5-100Starting and driving
.Keep your engine tuned up.
. Follow the recommended scheduled
maintenance.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases
tire wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
. Use the recommended viscosity engine
oil. (See “Engine oil and oil filter
recommendation” in the“9. Technical
and consumer information” section.)
WARNING
.Do not attempt 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
drivetrain 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 or
similar equipment even if the other two
wheels are raised off the ground. Make
sure you inform test facility personnel
that your vehicle is equipped with 4WD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or
personal injury.
CAUTION
.Do not drive the vehicle in the 4HI or 4LO
position on dry hard surface roads.
Driving on dry, hard surfaces in 4HI or 4LO may cause unnecessary noise, tire
wear and increased fuel consumption.
If the Four-Wheel Drive (4WD) warning
light turns on when driving on dry hard
surface roads:
—in the 4HI position, shift the 4WD
shift switch to AUTO.
—in the 4LO position, stop the vehicleand shift the transmission lever to
the N (Neutral) position with the
brake pedal depressed and shift the
4WD shift switch to AUTO.
If the 4WD warning light is still on
after the above operation, have your
vehicle checked by an INFINITI retai-
ler as soon as possible.
. The transfer case may be damaged if you
continue driving with the 4WD warning
light blinking.
See “On-pavement and off-road driving
precautions” earlier in this section for
other precautions for offroad driving.

Warning light and display
When the Preview Function is not operating
properly, the chime sounds and the system
warning light (orange) will come on.
Action to take:
If the warning light comes on, park the
vehicle in a safe place. Turn the engine off,
restart the engine and resume driving.
If the indicator stays on, it may indicate
that the Preview Function is malfunction-
ing (the brake is operative). Although the
Vehicle is still driveable under normal
conditions, have the vehicle checked at
an INFINITI retailer.
How to handle the sensor
The sensor for the Preview Function is
common with Intelligent Cruise Control and
is located below the front bumper.
To keep the Preview Function operating
properly, be sure to observe the following:
.Always keep the sensor clean. Wipe
with a soft cloth carefully so as not to
damage the sensor.
. Do not strike or damage the areas
around the sensor. Do not touch or
remove the screw located on the
sensor. Doing so could cause failure
or malfunction. If the sensor is da-
maged due to an accident, contact an
INFINITI retailer.
. Do not attach a sticker (including
transparent material) or install an
accessory near the sensor. This could
cause failure or malfunction.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
. The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless or
dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remember
that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if you
are using tire chains. Always maintain a
safe distance from the vehicle 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 spare tire, make
sure that it is the proper size and
type as specified on the Tire and
Loading Information label. See “Tire
Starting and driving5-113

Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow
tires.
Tire chains may be used. For details, see
“Tire chains”in the“8. Maintenance and
do-it-yourself” section of this manual.
For four-wheel drive
If you install snow tires, they must also be
the same size, brand, construction and
tread pattern on all four wheels.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
.A scraper and stiff-bristled brush to
remove ice and snow from the windows
and wiper blades.
. A sturdy, flat board to be placed under
the jack to give it firm support.
. A shovel to dig the vehicle out of
snowdrifts.
. Extra window washer fluid to refill the
reservoir tank.
DRIVING ON SNOW OR ICE
WARNING
. Wet ice (328F, 0 8C 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 the cruise control on slippery
roads.
. Snow can trap dangerous exhaust gases
under your vehicle. Keep snow clear of
the exhaust pipe and from around your
vehicle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist in
cold temperature starting.
The engine block heater should be used
when the outside temperature is 208 F
(−78C) or lower.
To use the engine block heater
1. Turn the engine off.
2. Open the hood and unwrap the engine
block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension
cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected,
grounded 110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least 2 - 4 hours,

To shut off the engine in an emergency
situation while driving, perform the follow-
ing procedure:
.Rapidly push the push-button ignition
switch 3 consecutive times in less than
1.5 seconds, or
. Push and hold the push-button ignition
switch for more than 2 seconds.TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the CHECK TIRE
PRESSURE warning appears in the dot
matrix liquid crystal display, one or more
of your tires is significantly under-inflated.
If the vehicle is being driven with low tire
pressure, the TPMS will activate and warn
you of it by the low tire pressure warning
light. This system will activate only when
the vehicle is driven at speeds above 16
MPH (25 km/h). For more details, see
“Warning/indicator lights and audible re-
minders” in the“2. Instruments and
controls” section,“TIRE PRESSURE infor-
mation” in the“4. Monitor, climate, audio,
phone and voice recognition systems”
section and “Tire Pressure Monitoring
System (TPMS)” in the“5. Starting and
driving” section.
WARNING
.If the low tire pressure warning light
illuminates or LOW PRESSURE informa- tion is displayed on the monitor screen
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 likelihood of tire fail-
ure. Serious vehicle damage could occur
and may lead to an accident 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 Information label to turn
the low tire pressure warning light OFF. If
the light still illuminates while driving
after adjusting the tire pressure, a tire
may be flat. If you have a flat tire,
replace it with a spare tire as soon as
possible.
. When a spare tire is mounted or a wheel
is replaced, 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.
Contact your INFINITI retailer as soon as
possible for tire replacement and/or
system resetting.

TOWING RECOMMENDED BY INFINITI
Two-Wheel Drive (2WD) models
INFINITI recommends that your vehicle be
towed with the driving (rear) wheels off the
ground or place the vehicle on a flat bed
truck as illustrated.
CAUTION
.Never tow automatic transmission mod-
els with the rear wheels on the ground
or four wheels on the ground (forward or
backward), as this may cause serious and expensive damage to the transmis-
sion. If it is necessary to tow the vehicle
with the front wheels raised, always use
towing dollies under the rear wheels.
. When towing rear wheel drive models
with the front wheels on the ground or
on towing dollies: Place the ignition in
the ACC or ON position, and secure the
steering wheel in a straight-ahead posi-
tion with a rope or similar device.

wheel or tire even if it has been repaired.
Such wheels or tires could have struc-
tural damage and could fail without
warning.
. The use of retread tire is not recom-
mended.
. For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or“Tire Safety Infor-
mation” (Canada) in the Warranty Infor-
mation Booklet.
Four-wheel Drive (4WD) models
CAUTION
. Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may
damage the transmission, transfer case
and differential gears.
. ONLY use spare tires specified for the
4WD model.
If excessive tire wear is found, it is
recommended that all four tires be re-
placed 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.
Contact an INFINITI retailer.
Wheel balance
Unbalanced wheels may affect vehicle
handling and tire life. Even with regular
use, wheels can get out of balance. There-
fore, they should be balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada)
in the INFINITI Warranty Information Book-
let.
Care of wheels
See “Cleaning exterior” in the“7. Appear-
ance and care” section for details about
care of the wheels.
Spare tire
When a spare tire is mounted (TEMPORARY
USE ONLY or conventional), the TPMS will
not function.
Spare tire (FULL-SIZE TEMPORARY USE
ONLY spare tire) (Applies ONLY to vehicles
equipped with P275/50R22 tires):
Observe the following precautions if the
full-size temporary use only spare tire must
be used, otherwise your vehicle could be
damaged or involved in an accident.
WARNING
. The full-size temporary use only spare
tire should be used for emergency use. It
should be replaced with the standard
tire at the first opportunity to avoid
possible tire or differential damage
. Drive carefully while the spare tire is
installed. Avoid sharp turns and abrupt
braking while driving. The vehicle driv-
ing performance may be affected when
driving on wet or snow covered roads.
. When the spare tire is installed, the
following systems may not work cor-
rectly.
