INFINITI VEHICLE IMMOBILIZER
SYSTEM
The INFINITI Vehicle Immobilizer System will
not allow the engine to start without the use
of the registered key.
If the engine fails to start using the registered
key, it may be due to interference caused by
another registered key, an automated toll
road device or automated payment device on
the key ring. Restart the engine using the
following procedures:1. Leave the ignition switch in the ON po- sition for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position and wait approximately
5 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the inter-
ference) separate from the registered
key.
If the no start condition re-occurs, INFINITI
recommends placing the registered key on a
separate key ring to avoid interference from
other devices. ∙ Make sure the area around the vehicle is
clear.
∙ Check fluid levels such as engine oil, cool- ant, brake fluid, and windshield-washer
fluid as frequently as possible, or at least
whenever you refuel.
∙ Check that all windows and lights are clean.
∙ Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
∙ Check that all doors are closed.
∙ Position seat and adjust head restraints/headrests.
∙ Adjust inside and outside mirrors.
∙ Fasten seat belts and ask all passengers to do likewise.
∙ Check the operation of warning lights when the ignition switch is placed in the
ON position. For additional information,
refer to “Warning lights, indicator lights
and audible reminders” in the “Instru-
ments and controls” section of this
manual. 1. Apply the parking brake.
2. Press the Park button to place the ve-
hicle in P (Park) or move the shift lever to
N (Neutral). P (Park) is recommended.
The starter is designed not to operate if
the shift lever is in any of the driving
positions.
3. Push the ignition switch to the ON posi- tion. Depress the brake pedal and push
the ignition switch to start the engine.
To start the engine immediately, push
and release the ignition switch while de-
pressing the brake pedal with the ignition
switch in any position.
∙ If the engine is very hard to start in extremely cold weather or when re-
starting, depress the accelerator pedal
a little (approximately 1/3 to the floor)
and while holding, crank the engine.
Release the accelerator pedal when
the engine starts.
BEFORE STARTING THE ENGINE STARTING THE ENGINE
Starting and driving5-17

switch in the OFF position and wait for
10 seconds. Then place the ignition switch
back in the ON position. The vehicle should
return to its normal operating condition. If it
does not return to its normal operating con-
dition, have the transmission checked and
repaired, if necessary. It is recommended
that you visit an INFINITI retailer for this
service.
WARNING
When the high fluid temperature protec-
tion mode or fail-safe operation occurs, ve-
hicle speed may be gradually reduced. The
reduced speed may be lower than other
traffic, which could increase the chance of a
collision. Be especially careful when driving.
If necessary, pull to the side of the road at a
safe place and allow the transmission to re-
turn to normal operation, or have it re-
paired if necessary.
WARNING
∙ Be sure the parking brake is fully releasedbefore driving. Failure to do so can cause
brake failure and lead to an accident.
∙ Do not release the parking brake from outside the vehicle.
∙ Do not use the shift lever in place of the parking brake. When parking, be sure the
parking brake is fully engaged. ∙ To help avoid risk of injury or death
through unintended operation of the ve-
hicle 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.
The electronic parking brake can be applied
or released automatically or by operating the
parking brake switch.
AUTOMATIC OPERATION
The electronic parking brake will apply auto-
matically if the ignition switch is placed in the
OFF position when the brake force is main-
tained by the automatic brake hold function.
The electronic parking brake is automatically
released as soon as the vehicle starts and the
accelerator pedal is depressed.
The driver’s seat belt needs to be fastened.

5-24Starting and driving

– When installing a spare tire, make surethat it is the proper size and type as
specified on the Tire and Loading In-
formation label. For additional infor-
mation, refer to “Tire and Loading In-
formation label” in the “Technical and
consumer information” section of this
manual.
– For additional information, refer to “Wheels and tires” in the “Do-it-
yourself” section of this manual.
The ABS controls the brakes so the wheels do
not lock during hard braking or when braking
on slippery surfaces. The system detects the
rotation speed at each wheel and varies the
brake fluid pressure to prevent each wheel
from locking and sliding. By preventing each
wheel from locking, the system helps the
driver maintain steering control and helps to
minimize swerving and spinning on slippery
surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate to pre-
vent 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.
Self-test feature
The Anti-lock Braking System (ABS) includes
electronic sensors, electric pumps, hydraulic
solenoids and a computer. The computer has
a built-in diagnostic feature that tests the
system each time you start the engine and
move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may
hear a “clunk” noise and/or feel a pulsation in
the brake pedal. This is normal and does not
indicate a malfunction. If the computer
senses a malfunction, it switches the ABS off
and illuminates the ABS warning light on the
instrument panel. The brake system then op-
erates normally but without anti-lock assis-
tance.
If the ABS warning light illuminates during
the self-test or while driving, have the vehicle
checked. It is recommended that you visit an
INFINITI retailer for this service.
Normal operation
The Anti-lock Braking System (ABS) operates
at speeds above3-6mph(5-10km/h). The
speed varies according to road conditions. When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsation
in the brake pedal and hear a noise from
under the hood or feel a vibration from the
actuator when it is operating. This is normal
and indicates that the ABS is operating prop-
erly. However, the pulsation may indicate
that road conditions are hazardous and extra
care is required while driving.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional brake booster even with
light pedal force.
WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the driv-
er’s responsibility to stay alert, drive safely
and be in control of the vehicle at all times.

DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For additional information, refer to
“Changing engine coolant” in the “Do-it-
yourself” section of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate 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 infor-
mation.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing 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.
3. Tire chains may be used. For additional information, refer to “Tire chains” in the
“Do-it-yourself” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
∙ A scraper and stiff-bristled brush to re- move 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 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 the cruise control on slippery roads.
