∙ Use a heavy-duty 3-wire, 3-pronged ex-tension cord rated for at least 10 A. Plug
the extension cord into a Ground Fault
Interrupt (GFI) protected, grounded
110-VAC outlet. Failure to use the
proper extension cord or a grounded out-
let can result in a fire or electrical shock
and cause serious personal injury.
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 least2-4hours, de-
pending on outside temperatures, to
properly warm the engine coolant. Use
an appropriate timer to turn the engine
block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away
from moving parts.
ACTIVE NOISE CANCELLATION
This system uses microphones1located in-
side the vehicle to detect engine booming
noise. The system then automatically gener-
ates a noise canceling sound through the
speakers and woofer (if so equipped) to re-
duce engine booming noise.
NOTE:
To operate the active noise cancellation sys-
tem properly:
∙ Do not cover the speakers or woofer (if
so equipped).

5-194Starting and driving

Add a washer solvent to the washer for bet-
ter cleaning. In the winter season, add a
windshield-washer antifreeze. Follow the
manufacturer’s instructions for the mixture
ratio.
Refill the reservoir more frequently when
driving conditions require an increased
amount of windshield-washer fluid.
Recommended fluid is Genuine NISSAN
Windshield Washer Concentrate Cleaner &
Antifreeze or equivalent.
CAUTION
∙ Do not substitute engine antifreeze cool-ant for windshield-washer fluid. This
may result in damage to the paint.
∙ Do not fill the windshield-washer fluid reservoir with washer fluid concentrates
at full strength. Some methyl alcohol
based washer fluid concentrates may
permanently stain the grille if spilled
while filling the windshield-washer fluid
reservoir. ∙ Pre-mix washer fluid concentrates with
water to the manufacturer’s recom-
mended levels before pouring the fluid
into the windshield-washer fluid reser-
voir. Do not use the windshield-washer
fluid reservoir to mix the washer fluid
concentrate and water. ∙ If the battery is labeled "do not open" it is
maintenance free and battery fluid
should not be checked. It is recom-
mended that you visit an INFINITI retailer
or a qualified specialist workshop to con-
firm the battery’s performance.
∙ Keep the battery surface clean and dry. Clean the battery with a solution of bak-
ing soda and water.
∙ Make certain the terminal connections are clean and securely tightened.
∙ If the vehicle is not to be used for 30 days or longer, disconnect the negative (-) bat-
tery terminal cable to prevent discharge.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as: 1. Installation or extended use of elec-
tronic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc).
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
