battery INFINITI QX80 2014 Service Manual

Once a cellular phone is connected to the
in-vehicle phone module, no phone con-
necting procedure is required anymore.
Your phone is automatically connected
with the in-vehicle phone module when
the ignition switch is pushed to the ON
position with the registered cellular phone
turned on and carried in the vehicle.
You can register up to 5 different Blue-
tooth
®cellular phones in the in-vehicle
phone module. However, you can talk on
only one cellular phone at a time.
The INFINITI Voice Recognition system
supports the phone commands, so dialing
a phone number using your voice is
possible. For more details, see “INFINITI
Voice Recognition system” later in this
section; page 4-109.
Before using the Bluetooth
®Hands-Free
Phone System, refer to the following notes.
. Wireless LAN (Wi-Fi) and the Bluetooth
®
functions share the same frequency
band (2.4 GHz). Using the Bluetooth®
and the wireless LAN functions at the
same time may slow down or discon-
nect the communication and cause
undesired noise. It is recommended
that you turn off the wireless LAN (Wi-
Fi) when using the Bluetooth
®func- tions.
. Set up the wireless connection between
a compatible cellular phone and the in-
vehicle phone module before using the
Bluetooth
®Hands-Free Phone System.
. Some Bluetooth®enabled cellular
phones may not be recognized by the
in-vehicle phone module. Please visit
www.InfinitiUSA.com/bluetooth for a
recommended phone list.
. You will not be able to use a hands-free
phone under the following conditions:
— Your vehicle is outside of the tele-
phone service area.
— Your vehicle is in an area where it is
difficult to receive radio waves; such
as in a tunnel, in an underground
parking garage, behind a tall build-
ing or in a mountainous area.
— Your cellular phone is locked in
order not to be dialed.
. When the radio wave condition is not
ideal or ambient sound is too loud, it
may be difficult to hear the other
person’s voice during a call.
. Immediately after the ignition switch is
pushed to the ON position, it may be
impossible to receive a call for a short
period of time. .
Do not place the cellular phone in an
area surrounded by metal or far away
from the in-vehicle phone module to
prevent tone quality degradation and
wireless connection disruption.
. While a cellular phone is connected
through the Bluetooth®wireless con-
nection, the battery power of the
cellular phone may discharge quicker
than usual.
. If the Bluetooth
®Hands-Free Phone
System seems to be malfunctioning,
please visit www.InfinitiUSA.com/blue-
tooth for troubleshooting help.
. Some cellular phones or other devices
may cause interference or a buzzing
noise to come from the audio system
speakers. Storing the device in a
different location may reduce or elim-
inate the noise.
. Refer to the cellular phone Owner’s
Manual regarding the telephone pairing
procedure specific to your phone,
battery charging, cellular phone anten-
na, etc.
. The antenna display on the monitor will
not coincide with the antenna display
of some cellular phones.

To prevent a door lock from freezing, apply
deicer through the key hole. If the lock
becomes frozen, heat the key before
inserting it into the key hole or use the
Intelligent Key system.
ANTIFREEZE
In the winter when it is anticipated that the
outside temperature will drop below 328F
(08C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” in the
“8. Maintenance and do-it-yourself” sec-
tion.
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “Battery”in
the “8. Maintenance and do-it-yourself”
section.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system” in the“8. Main-
tenance and do-it-yourself” section.
TIRE EQUIPMENT
SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your
vehicle on snowy or icy roads, INFINITI
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels.
Consult an INFINITI retailer for the tire
type, size, speed rating and availability
information.
For additional traction on icy roads,
studded tires may be used. However, some
U.S. states and Canadian provinces prohi-
bit their use. Check local, state and
provincial laws before installing studded
tires.
Starting and driving5-117
COLD WEATHER DRIVING

is recommended that wheel nuts be
tightened to specifications at each
lubrication interval.
.Adjust tire pressure to the COLDpressure.
COLD pressure:
After the vehicle has been parked
for three hours or more or driven
less than 1 mile (1.6 km).
COLD tire pressures are shown on
the Tire and Loading Information
label affixed to the driver side center
pillar.
After adjusting tire pressure to the COLD
tire pressure, the display of the tire
pressure information may show higher
pressure than the COLD tire pressure after
the vehicle has been driven more than 1
mile (1.6 km). This is because the tire
pressurizes as the tire temperature rises.
This does not indicate a system malfunc-
tion.
Stowing the damaged tire and tools
1. Securely store the damaged tire, jack and tools in the storage area.
2. Close the cargo floor cover.
3. Replace the cargo floor board.
4. Close the lift gate.
WARNING
. Always make sure that the spare tire and
jacking equipment are properly secured
after use. Such items can become
dangerous projectiles in an accident or
sudden stop.
. The full-size temporary use only spare
tire (if so equipped) is designed for
emergency use. (See specific instruc-
tions under the heading “Wheels and
tires” in the “8. Maintenance and do-it-
yourself” section.)
To start your engine with a booster battery,
the instructions and precautions below
must be followed.
WARNING
.If done incorrectly, jump starting can
lead to a battery explosion, resulting in
severe injury or death. It could also
damage your vehicle.
. Explosive hydrogen gas is always pre-
sent in the vicinity of the battery. Keep
all sparks and flames away from the
battery.
. Do not allow battery fluid to come into
contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a
corrosive sulphuric acid solution which
can cause severe burns. If the fluid
should come into contact with anything,
immediately flush the contacted area
with water.
. Keep the battery out of the reach of
children.
. The booster battery must be rated at 12
volts. Use of an improperly rated battery
can damage your vehicle.
