WARNING
Always follow the instructions below. Failure
to do so could result in damage to the
charging system and cause personal injury.
1. Remove the engine compartment cover,if necessary. See “Engine compartment
check locations ”(P.8-7).
2. If the booster battery is in another vehicle
*A, position the two vehicles
(
*Aand*B) to bring their batteries
into close proximity to each other.
Do not allow the two vehicles to touch.
3. Apply parking brake. Move the shift lever to the P (Park) position. Switch off
all unnecessary electrical systems
(light, heater, air conditioner, etc.).
4. Remove vent caps on the battery (if so equipped). Cover the battery with a
firmly wrung out moist cloth
*Cto
reduce explosion hazard.
5. Connect jumper cables in the sequence as illustrated (
*1?*2?*3?*4).

7-4Appearance and care
ambient temperature.
. Rinse the wheel to completely remove
the cleaner within 15 minutes after the
cleaner is applied.
CHROME PARTS
Clean chrome parts regularly with a non-
abrasive chrome polish to maintain the
finish.
TIRE DRESSING
INFINITI does not recommend the use of
tire dressings. Tire manufacturers apply a
coating to the tires to help reduce dis-
coloration of the rubber. If a tire dressing is
applied to the tires, it may react with the
coating and form a compound. This com-
pound may come off the tire while driving
and stain the vehicle paint.
If you choose to use a tire dressing, take
the following precautions:
.Use a water-based tire dressing. The
coating on the tire dissolves more
easily with an oil-based tire dressing.
. Apply a light coat of tire dressing to
help prevent it from entering the tire
tread/grooves (where it would be diffi-
cult to remove). .
Wipe off excess tire dressing using a
dry towel. Make sure the tire dressing
is completely removed from the tire
tread/grooves.
. Allow the tire dressing to dry as
recommended by tire dressing manu-
facturer. Occasionally remove loose dust from the
interior trim, plastic parts and seats using
a vacuum cleaner or soft bristled brush.
Wipe the vinyl and leather surfaces with a
clean, soft cloth dampened in mild soap
solution, then wipe clean with a dry soft
cloth.
Regular care and cleaning is required in
order to maintain the appearance of the
leather.
Before using any fabric protector, read the
manufacturer’
s recommendations. Some
fabric protectors contain chemicals that
may stain or bleach the seat material.
Use a cloth dampened only with water, to
clean the meter and gauge lens.
WARNING
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classification
sensors. This can also affect the operation
of the air bag system and result in serious
personal injury.

seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints move up
and down smoothly and that the locks (if
so equipped) hold securely in all latched
positions.
Steering wheel:Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly
and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery*: Check the fluid level in each cell.
It should be between the MAX and MIN
lines. Vehicles operated in high tempera- tures or under severe condition require
frequent checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1.
Installation or extended use of electro-
nic 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.
Brake fluid level*: Make sure that the
brake fluid level is between the MAX and
MIN lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no belt
is frayed, worn, cracked or oily.
Engine oil level*: Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil pan.
Exhaust system:
Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in-
spected by an INFINITI retailer. (See
“Precautions when starting and driving”
(P.5-3) section for exhaust gas (carbon
monoxide).)
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks or
if gasoline fumes are evident, check for the
cause and have it corrected immediately.
Power steering fluid level* and lines:
Check the level when the fluid is cold,
with the engine off. Check the lines for
proper attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as

8-24Maintenance and do-it-yourself
Contact an INFINITI retailer if checking or
replacement is required.If the brakes do not operate properly, have
the brakes checked by an INFINITI retailer.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjust-
ing brakes.
The disc-type brakes self-adjust every time
the brake pedal is applied.
WARNING
See an INFINITI retailer for a brake system
check if the brake pedal height does not
return to normal.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear
warnings. When a brake pad requires
replacement, it will make a high pitched
scraping sound when the vehicle is in
motion. This scraping sound will first occur
only when the brake pedal is depressed.
After more wear of the brake pad, the
sound will always be heard even if the
brake pedal is not depressed. Have the
brakes checked as soon as possible if the
wear warning sound is heard.
Under some driving or climate conditions,occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is
normal and does not affect the function or
performance of the brake system.
Proper brake inspection intervals should
be followed.
For additional information,
see the maintenance log section of your
“INFINITI Service and Maintenance Guide”
for maintenance intervals.

HEADLIGHTS
Replacing
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 retailer.
Xenon headlight bulb:
If replacement is required, see an INFINITI
retailer.
WARNING
HIGH VOLTAGE
When xenon headlights are on, they pro-
duce a high voltage. To prevent an electric
shock, never attempt to modify or disas-
semble. Always have your xenon headlights
replaced at an INFINITI retailer. For addi-
tional information, see “Headlight and turn
signal switch” (P.2-38).

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 and the CHECK TIRE
PRESSURE warning appears on the dot
matrix liquid crystal display, 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
warning light” (P.2-16),“Tire Pressure
Monitoring System (TPMS)” (P.5-4) and
“Tire Pressure Monitoring System (TPMS)”
(P.6-3).
Tire inflation pressure
Check the pressure of the tires
(including the spare) often and al- ways prior to long distance trips. The
recommended tire pressure specifi-
cations are shown on the Tire and
Loading Information label under the
“Cold Tire Pressure”
heading. The
Tire and Loading Information 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 whendriven 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
moderate speeds.
Incorrect tire pressure, including
under inflation, may adversely affect
tire life and vehicle handling.
