Follow these easy-to-use Fuel Efficient Driv-
ing Tips to help you achieve the most fuel
economy from your vehicle.
1.Use Smooth Accelerator and Brake Pedal
Application
•Avoid rapid starts and stops.
•Use smooth, gentle accelerator and
brake application whenever possible.
•Maintain constant speed while com-
muting and coast whenever possible.
2.Maintain Constant Speed
•Look ahead to try and anticipate and
minimize stops.
•Synchronizing your speed with traffic
lights allows you to reduce your num-
ber of stops.
•Maintaining a steady speed can mini-
mize red light stops and improve fuel
efficiency.
3.Use Air Conditioning (A/C) at Higher
Vehicle Speeds
•Below 40 MPH (64 km/h), it is more
efficient to open windows to cool the
vehicle due to reduced engine load.
•Above 40 MPH (64 km/h), it is more
efficient to use A/C to cool the vehicle
due to increased aerodynamic drag.
•Recirculating the cool air in the cabin
when the A/C is on reduces cooling
load.
4.
Drive at Economical Speeds and Distances
•Observing the speed limit and not ex-
ceeding 60 MPH (97 km/h) (where le-
gally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag.
•Maintaining a safe following distance
behind other vehicles reduces unneces-
sary braking.
•Safely monitoring traffic to anticipate
changes in speed permits reduced brak-
ing and smooth acceleration changes.
•Select a gear range suitable to road
conditions.
5.Use Cruise Control
•Using cruise control during highway
driving helps maintain a steady speed.
•Cruise control is particularly effective in
providing fuel savings when driving on
flat terrains.
Utilize a map or navigation system to deter-
mine the best route to save time.6.Avoid Idling
•Shutting off your engine when safe for
stops exceeding 30 seconds saves fuel
and reduces emissions.
7.Buy an Automated Pass for Toll Roads
•Automated passes permit drivers to
use special lanes to maintain cruising
speed through the toll and avoid stop-
ping and starting.
8.Winter Warm Up
•Limit idling time to minimize impact to
fuel economy.
•Vehicles typically need no more than
30 seconds of idling at start-up to ef-
fectively circulate the engine oil before
driving.
•Your vehicle will reach its ideal operat-
ing temperature more quickly while
driving versus idling.
9.Keeping your Vehicle Cool
•Park your vehicle in a covered parking
area or in the shade whenever possible.
•When entering a hot vehicle, opening
the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system.
FUEL EFFICIENT DRIVING TIPS
Starting and driving5-85

•Do not place the ignition switch in the on
position while the steering wheel or a
tire is removed.
•Do not turn the steering wheel as much
as possible while the ignition switch is in
any position other than the ON position.
•Installing an accessory on the steering
wheel, or changing the steering wheel,
may reduce the steering performance.
NOTE
When the steering wheel is operated repeat-
edly or continuously while parking or driving
at a very low speed, the power assistance for
the steering wheel will be reduced. This is to
prevent overheating of the electric power
steering system and protect it from becom-
ing damaged. While the power assistance is
reduced, steering wheel operation will be-
come heavy. When the temperature of the
electric power steering system decreases,
the power assistance level will return to nor-
mal. Avoid repeating such steering wheel
operations that could cause the electric
power steering system to overheat.The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will
still have braking ability at two wheels.
BRAKE PRECAUTIONS
WARNING
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or acceler-
ating could cause the wheels to skid and
result in an accident.
Vacuum assisted brakes
The brake booster aids braking by using en-
gine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on the
brake pedal will be required to stop the ve-
hicle. The stopping distance will be longer.
WARNING
•If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
•Do not coast with the engine stopped.When the brake pedal is depressed slowly
and firmly, you may hear a clicking noise and
feel a slight pulsation. This is normal and
indicates that the Brake Assist System is op-
erating (if equipped).
Using brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake linings/pads faster, and
increase fuel consumption.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down
a slope or long grade. Overheated brakes
may reduce braking performance and could
result in loss of vehicle control.
While driving on a slippery surface, be careful
when braking, accelerating or downshifting.
Abrupt braking or acceleration could cause
the wheels to skid and result in an accident.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result,
your braking distance will be longer and the
vehicle may pull to one side during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly depressing the brake
pedal to heat up the brakes. Do this until the
BRAKE SYSTEM
5-90Starting and driving

Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer.
The computer has a built-in diagnostic fea-
ture 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 mal-
function. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates
the ABS warning light on the instrument
panel. The brake system then operates nor-
mally, but without anti-lock assistance. If the
ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked. It is recommended you visit an
INFINITI retailer for this service.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h). The speed varies ac-
cording 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.The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving
conditions, the VDC system helps to perform
the following functions.
•Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power is
transferred to a non slipping drive wheel
on the same axle.
•Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function).
•Controls brake pressure at individual
wheels and engine output to help the
driver maintain control of the vehicle in the
following conditions:
– understeer (vehicle tends to not follow
the steered path despite increased
steering input)
– oversteer (vehicle tends to spin due to
certain road or driving conditions).
The VDC system can help the driver to main-
tain control of the vehicle, but it cannot pre-
vent loss of vehicle control in all driving situ-
ations.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-92Starting and driving

When the VDC system operates, the VDC
warning light in the instrument panel flashes
so note the following:
•The road may be slippery or the system
may determine some action is required to
help keep the vehicle on the steered path.
•You may feel a pulsation in the brake pedal
and hear a noise or vibration from under
the hood. This is normal and indicates that
the VDC system is working properly.
•Adjust your speed and driving to the road
conditions.
See " Vehicle Dynamic Control (VDC) warning
light".
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system automati-
cally turns off.
WARNING
•The VDC system is designed to help the
driver maintain stability but does not
prevent accidents due to abrupt steer-
ing operation at high speeds or by care-
less or dangerous driving techniques.Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces and always drive care-
fully.
•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 VDC system
may not operate properly. This could
adversely affect vehicle handling per-
formance, and the VDC warning light
may illuminate.
•If brake related parts such as brake
pads, rotors and calipers are not
INFINITI recommended or are extremely
deteriorated, the VDC system may not
operate properly and the VDC warning
light
may illuminate.
•If engine control related parts are not
INFINITI recommended or are extremely
deteriorated, the VDC warning light
may illuminate.
•When driving on extremely inclined sur-
faces such as higher banked corners, the
VDC system may not operate properly and
the VDC warning light
may illuminate.
Do not drive on these types of roads.
•When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the VDC warning light
may
illuminate. This is not a malfunction.
Restart the engine after driving onto a
stable surface.
•If wheels or tires other than the INFINITI
recommended ones are used, the VDC
system may not operate properly and the
VDC warning light
may illuminate.
•The VDC system is not a substitute for
winter tires or tire chains on a snow cov-
ered road.
•If VDC is malfunctioning, VDC is unable
to stabilize the vehicle. In addition,
other driving safety systems are
switched off. This increases the risk of
skidding and an accident. Drive on care-
fully. Have VDC checked. It is recom-
mended you visit an INFINITI retailer for
this service.
Starting and driving5-93

CAUTION
•When VDC is deactivated, the
VDC OFF warning light lights up con-
tinuously.
•If both thewarning light and
warning light are lit continuously, VDC
is not available due to a malfunction.
TRACTION CONTROL SYSTEM
(TCS)
The Traction Control System (TCS) is part of
VDC.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side. In addition, more drive torque is trans-
ferred to the wheel or wheels with traction.
Traction control remains active if you deacti-
vate VDC.
CHARACTERISTICS OF VDC
If theVDC warning light goes out before
beginning the journey, VDC is automatically
active.If VDC intervenes, the
VDC warning
light flashes in the combination meter.
If VDC intervenes:
•Do not deactivate VDC under any circum-
stances.
•When pulling away, only depress the ac-
celerator pedal as far as is necessary.
•Adapt your driving style to suit the prevail-
ing road and weather conditions.
Deactivating/activating VDC
WARNING
If you deactivate VDC, VDC no longer
stabilizes the vehicle. There is an increased
risk of skidding and an accident.
Only deactivate VDC in the situations
described in the following section.
You can select between the following sta-
tuses of VDC:
•VDC is activated.
•VDC is deactivated.
It may be best to deactivate VDC in the fol-
lowing situations:
•When using snow chains.
•In deep snow.
•On sand or gravel.NOTE
Activate VDC as soon as the situations de-
scribed above no longer apply. VDC will oth-
erwise not be able to stabilize the vehicle if
the vehicle starts to skid or a wheel starts to
spin.
You can activate/deactivate VDC using the
vehicle information display. To activate/
deactivate VDC:
1. Start the engine
2. Press the
orbutton on the
steering wheel to select the [DriveAssist]
menu in the vehicle information display.
3. Press the
orbutton to select
VDC.
4. Press thebutton on the steering
wheel. The current selection is displayed.
5. To activate/deactivate: press the
button again.
VDC is deactivated if the
warning
light in the combination meter lights up
continuously when the engine is running.
Characteristics when VDC is deactivated:
If VDC is deactivated and one or more wheels
start to spin, the
VDC warning light
flashes in the combination meter. In such
situations, VDC will not stabilize the vehicle.
5-94Starting and driving

If you deactivate VDC:
•VDC no longer intervenes in understeer or
oversteer situations.
•Engine torque is no longer limited and the
drive wheels are able to spin.
The spinning of the wheels results in a
cutting action, so the tires cut through the
loose surface until the hit solid ground,
giving better traction.
•Traction control is still activated.
•VDC still provides support when you brake.
EBD (ELECTRONIC BRAKE
FORCE DISTRIBUTION)
EBD monitors and controls the brake pres-
sure on the rear wheels to help improve han-
dling during braking.
WARNING
If EBD is malfunctioning, the EBD [Inop-
erative See Operator's Manual] warning is
displayed in the vehicle information dis-
play. The
VDC warning light may also
light up.
If EBD is malfunctioning as a result of a
VDC malfunction, the rear wheels can lock,
e.g. under full braking. This increases the
risk of skidding and an accident.You should therefore adapt your driving
style to the different handling characteris-
tics. Have the brake system checked. It is
recommended you see an INFINITI retailer.
STEER CONTROL
STEER CONTROL helps you by transmitting
a noticeable steering force to the steering
wheel in the direction required for vehicle
stabilisation.
This steering support is provided in particular
if:
•Both right wheels or both left wheels are
on a wet or slippery road surface when
you brake.
•The vehicle starts to skid.
WARNING
No steering support is provided from
STEER CONTROL, if:
•VDC is malfunctioning.•The steering is faulty.
Power steering will, however, continue to
function.
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 re-
sult in a loss of control of the vehicle and
possible serious injury or death.
•The Hill Start Assist system is not de-
signed 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 colli-
sion or serious personal injury.
•The Hill Start Assist system may not
prevent the vehicle from rolling back-
wards on a hill under all load or road
conditions. Always be prepared to de-
press the brake pedal to prevent the
vehicle from rolling backwards. Failure
to do so may result in a collision or seri-
ous personal injury.

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.
