Replacing

Xenon headlight bulb

WARNING

HIGH VOLTAGE

When xenon headlights are on, they produce a

high voltage. To prevent an electric shock,

never attempt to modify or disassemble. Al-

ways have your xenon headlights replaced at

an INFINITI dealer. For additional information,

see “HEADLIGHT AND TURN SIGNAL SWITCH” in

the “2. Instruments and controls” section.

CAUTION

Use the same number and wattage as originally

installed:

High/Low beams (Xenon)

Wattage: 35

Bulb no.: D2S

If replacement is required, see an INFINITI

dealer.

Fog may temporarily form inside the lens of the

exterior lights in the rain or in a car wash. A

temperature difference between the inside and

the outside of the lens causes the fog. This is

not a malfunction. If large drops of water collect

inside the lens, contact an INFINITI dealer.

If you have a flat tire, see “FLAT TIRE” in the “6. In

case of emergency” section.

TIRE PRESSURE
Tire Pressure Monitoring System

(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, one or

more of your tires is significantly under-

inflated.
The TPMS will activate only when the vehicle is

driven at speeds above 16 MPH (25 km/h). Also,

this system may not detect a sudden drop in tire

pressure (for example a flat tire while driving).
For more details, see “Low tire pressure warn-

ing light” in the “2. Instruments and controls”

section, “TIRE PRESSURE MONITORING SYSTEM

(TPMS)” in the “5. Starting and driving” section

and “TIRE PRESSURE MONITORING SYSTEM

(TPMS)” in the “6. In case of emergency” sec-

tion.

Tire inflation pressure

Check the pressure of the tires (includ-
ing the spare) often and always prior to
long distance trips. The recommended

tire pressure specifications are shown
on the Tire and Loading Information
label under the “Cold Tire Pressure”
heading. The Tire and Loading Informa-
tion label is affixed to the driver side
center pillar. Tire pressures should be
checked regularly because:

●

Most tires naturally lose air over time.

●

Tires can lose air suddenly when
driven over potholes or other objects
or if the vehicle strikes a curb while
parking.

The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle has
been parked for 3 or more hours, or
driven less than 1 mile (1.6 km) at mod-
erate speeds.
Incorrect tire pressure, including under

inflation, may adversely affect tire life

and vehicle handling.

WARNING

●

Improperly inflated tires can fail sud-

denly and cause an accident.

●

The Gross Vehicle Weight rating

(GVWR) is located on the F.M.V.S.S./

C.M.V.S.S. label. The vehicle weight

capacity is indicated on the Tire and

Loading Information label. Do not

load your vehicle beyond this capac-

ity. Overloading your vehiclemay re-

sult in reduced tire life, unsafe operat-

ing conditions due to premature tire

failure, or unfavorable handling char-

acteristics and could also lead to a

serious accident. Loading beyond the

specified capacity may also result in

failure of other vehicle components.

●

Before taking a long trip, or whenever

you heavily load your vehicle, use a

tire pressure gauge to ensure that the

tire pressures are at the specified

level.

●

Do not drive your vehicle over 85 MPH

(137 km/h) unless it is equipped with

high speed rated tires. Driving faster

than 85 MPH (137 km/h) may result in

tire failure, loss of control and pos-

sible injury.

●

For additional information regarding

tires, refer to “Important Tire Safety

Information” (US) or “Tire Safety In-

formation” (Canada) in the Warranty

Information Booklet.

Checking the tire pressure

1.

Remove the valve stem cap from the
tire.

2.

Press the pressure gauge squarely
onto the valve stem. Do not press too
hard or force the valve stem side-
ways, or air will escape. If the hissing
sound of air escaping from the tire is
heard while checking the pressure,
reposition the gauge to eliminate this
leakage.

3.

Remove the gauge.

4.

Read the tire pressure on the gauge
stem and compare it to the specifica-
tion shown on the Tire and Loading
Information label.

5.

Add air to the tire as needed. If too
much air is added, press the core of
the valve stem briefly with the tip of
the gauge stem to release pressure.
Recheck the pressure and add or re-
lease air as needed.

6.

Install the valve stem cap.

7.

Check the pressure of all other tires,
including the spare.

TIRE LABELING

Federal law requires tire manufacturers to
place standardized information on the
sidewall of all tires. This information iden-
tifies and describes the fundamental char-
acteristics of the tire and also provides the
tire identification number (TIN) for safety
standard certification. The TIN can be used
to identify the tire in case of a recall.

s

1

Tire size (example: P215/60R16 94H)

TYPES OF TIRES

WARNING

● When changing or replacing tires, be sure all

four tires are of the same type (Example:

Summer, All Season or Snow) and construc-

tion. An INFINITI dealer may be able to help

you with information about tire type, size,

speed rating and availability.

● Replacement tires may have a lower speed

rating than the factory equipped tires, and

may not match the potential maximum ve-

hicle speed. Never exceed the maximum

speed rating of the tire.

● Replacing tires with those not originally

specified by INFINITI could affect the proper

operation of the TPMS.

● For additional information regarding tires,

refer to “Important Tire Safety Information”

(US) or “Tire Safety Information” (Canada) in

the Warranty Information Booklet.

All season tires

INFINITI specifies all season tires on some

models to provide good performance all year,

including snowy and icy road conditions. All

Season tires are identified by ALL SEASON

and/or M&S (Mud and Snow) on the tire side-

wall. Snow tires have better snow traction than

All Season tires and may be more appropriate in

some areas.

Summer tires

INFINITI specifies summer tires on some models

to provide superior performance on dry roads.

Summer tire performance is substantially re-

duced in snow and ice. Summer tires do not

have the tire traction rating M&S on the tire

sidewall.
If you plan to operate your vehicle in snowy or

icy conditions, INFINITI recommends the use of

SNOW tires or ALL SEASON tires on all four

wheels.

Snow tires

If snow tires are needed, it is necessary to

select tires equivalent in size and load rating to

the original equipment tires. If you do not, it can

adversely affect the safety and handling of your

vehicle.
Generally, snow tires will have lower speed

ratings than factory equipped tires and may not

match the potential maximum vehicle speed.

Never exceed the maximum speed rating of the

tire.
If you install snow tires, they must be the same

size, brand, construction and tread pattern on

all four wheels.
For additional traction on icy roads, studded

tires may be used. However, some U.S. states

and Canadian provinces prohibit their use.

Check local, state and provincial laws before

installing studded tires. Skid and traction capa-

bilities of studded snow tires, on wet or dry

surfaces, may be poorer than that of non-

studded snow tires.

TIRE CHAINS

Use of tire chains may be prohibited according

to location. Check the local laws before install-

ing tire chains. When installing tire chains,

make sure they are the proper size for the tires

on your vehicle and are installed according to

the chain manufacturer’s suggestions.

Use only

SAE Class S chains. Class “S” chains are used

on vehicles with restricted tire to vehicle clear-

ance. Vehicles that can use Class “S” chains are

designed to meet the SAE standard minimum

clearances between the tire and the closest

vehicle suspension or body component re-

quired to accommodate the use of a winter

traction device (tire chains or cables). The mini-

mum clearances are determined using the fac-

tory equipped tire size. Other types may dam-

age your vehicle. Use chain tensioners when

recommended by the tire chain manufacturer to

ensure a tight fit. Loose end links of the tire

chain must be secured or removed to prevent

the possibility of whipping action damage to

the fenders or underbody. If possible, avoid

fully loading your vehicle when using tire

chains. In addition, drive at a reduced speed.

Otherwise, your vehicle may be damaged

and/or vehicle handling and performance may

be adversely affected.

Tire chains must be installed only on the rear

wheels and not on the front wheels.
Never install tire chains on a TEMPORARY USE

ONLY spare tire.
Do not use tire chains on dry roads. Driving with

tire chains in such conditions can cause dam-

age to the various mechanisms of the vehicle

due to some overstress.
