Jacking up the vehicle and removing
the damaged tire
WARNING
. Never get under the vehicle while it is
supported only by the jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Use only the jack provided with your
vehicle to lift the vehicle. Do not use
the jack provided with your vehicle on
other vehicles. The jack is designed
for lifting only your vehicle during a
tire change.
. Use the correct jack-up points. Never
use any other part of the vehicle for
jack support.
. Never jack up the vehicle more than
necessary.
. Never use blocks on or under the jack.
. Do not start or run the INFINITI
Direct Response Hybrid
®System
while vehicle is on the jack, as it may
cause the vehicle to move. This is
especially true for vehicles with lim-
ited slip differentials.

the vehicle while it is on the jack.
Carefully read the caution label attached to
the jack body and the following instruc-
tions.
CE1089-A
Jack-up point
1. Place the jack directly under the jack-up point as illustrated so the top of the jack
contacts the vehicle at the jack-up point.
Align the jack head between the two
notches in the front or the rear as shown.
Also fit the groove of the jack head
between the notches as shown.
The jack should be used on level firm
ground.

2. Loosen each wheel nut one or two turnsby turning counterclockwise with the
wheel nut wrench. Do not remove the
wheel nuts until the tire is off the
ground.
3. Carefully raise the vehicle until the tire clears the ground. To lift the vehicle,
securely hold the jack lever and rod with
both hands as shown above. Remove the
wheel nuts, and then remove the tire.
SCE0661
Installing the spare tire
The T-type spare tire is designed for
emergency use. (See specific instructions
under the heading “Wheels and tires” (P.8-
26).)
1. Clean any mud or dirt from the surfacebetween the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly in the
sequence illustrated (
,,,,) until
they are tight.
4. Lower the vehicle slowly until the tire touches the ground. Then, with the
In case of emergency6-7

6-8In case of emergency
wheel nut wrench, tighten the wheel
nuts securely in the sequence illustrated.
Lower the vehicle completely.
WARNING
.Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
. Do not use oil or grease on the wheel
studs or nuts. This could cause the
nuts to become loose.
. Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
.As soon as possible, tighten the wheel
nuts to the specified torque with a
torque wrench.
Wheel nut tightening torque: 80 ft-lb (108 N·m)
The wheel nuts must be kept tigh-
tened to specification at all times. It
is recommended that wheel nuts be
tightened to specifications at each
lubrication interval.
.Adjust tire pressure to the COLD pressure.
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.

5. Securely store the flat tire and jacking
equipment in the vehicle.

6. Put trunk floor coveragainst in the
trunk room and store the damaged tire.
7. Close the trunk.
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 T-type spare tire and small size
spare tire are designed for emergency
use. See specific instructions under
the heading “Wheels and tires” (P.8- 26).
Before attempting to jump start the vehicle,
make sure the fuel tank is not empty and the
correct starting procedure is followed. See
“Starting the INFINITI Direct Response
Hybrid
®System” (P.5-13). Do not drive the
vehicle on battery power only if the fuel tank
is empty. The Lithium ion (Li-ion) battery will
become discharged and the INFINITI Direct
Response Hybrid
®System will turn off.
CONFIRM BATTERY IS DIS-
CHARGED
If any of the following conditions occurs, the
12-volt battery might discharged:
. The instrument cluster and/or headlights
are not normal brightness.
. Audio accessories cannot be turned on.
. The hybrid system does not become
READY to drive mode.
. The ignition switch cannot be placed in
the ON position.
Check the following if you notice above
conditions.
1. Check that the 12-volt battery terminals are tight and clean. See “12-volt battery”
(P.8-13). The battery is located on the
left hand side of the trunk behind an
access panel. If the 12-volt battery
terminals are loose, it is recommended
you contact your INFINITI retailer.

IF THE VEHICLE DOES NOT START

6-10In case of emergency
2. If the 12-volt battery terminals are tightand clean, try to jump start the vehicle.
See “Jump starting” (P.6-10).
If the hybrid system still does not start, it is
recommended that you contact an INFINITI
retailer. To start your INFINITI Direct Response
Hybrid®System with a booster battery, the
instructions and precautions below must be
followed.
Jump starting provides power to the 12 volt
system to allow the electrical systems to
operate. The electrical systems must be
operating to allow the Lithium ion (Li-ion)
battery to be charged. Jump starting does
not charge the Li-ion battery.
WARNING
. If done incorrectly, jump starting can
lead to a 12-volt battery explosion,
resulting in severe injury or death. It
could also damage your vehicle.
. Explosive hydrogen gas is always
present in the vicinity of the 12-volt
battery. Make sure that the vent
tube is mounted.
. Do not allow battery fluid to come
into contact with eyes, skin, clothing
or painted surfaces. Battery fluid is a
corrosive sulfuric acid solution which
can cause severe burns. If the fluid
should come into contact with any-
thing, immediately flush the con-
tacted area with water.
. Keep the 12-volt 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.
. Whenever working on or near a 12-
volt battery, always wear suitable
eye protectors (for example, goggles
or industrial safety spectacles) and
remove rings, metal bands, or any
other jewelry. Do not lean over the
12-volt battery when jump starting.
. Do not attempt to jump start a
frozen battery. It could explode and
cause serious injury.
. Your vehicle has an automatic engine
cooling fan. It could come on at any
time. Keep hands and other objects
away from it.
CAUTION
Do not attempt to jump start a hybrid
vehicle as a booster vehicle.
JUMP STARTING

JVE0010X
WARNING
Always follow the instructions below.
Failure to do so could result in damage to
the charging system and cause personal
injury.
1. If the booster battery is in another vehicle
, position the two vehicles (and) to bring the 12-volt battery and
fuse box into close proximity to each
other.
Do not allow the two vehicles to touch. 2. Apply parking brake. Move the shift lever
to the P (Park) position. Switch off all
unnecessary electrical systems (light,
heater, air conditioner, etc.).
3. Connect jumper cables in the sequence as illustrated (
???).
For models with a steering wheel lock
mechanism: If the 12-volt battery is
disconnected or discharged, the steering
wheel will lock and cannot be turned.
Supply power using jumper cables be-
fore pushing the ignition switch and
disengaging the steering lock.
CAUTION
. Always connect positive (+) to posi-
tive (+) and negative (−) to body
ground (as illustrated) − not to the
12-volt battery.
. Make sure the jumper cables do not
touch moving parts in the engine
compartment and that clamps do
not contact any other metal.
4. Start the engine of the booster vehicle
and let it run for a few minutes.
5. Start the hybrid system of the vehicle being jump started
.
CAUTION
If the hybrid system does not start right
away, push the ignition switch to the
OFF position and wait 10 seconds
before trying again.
6. After starting your vehicle, carefully disconnect the negative cable and then
the positive cable (
???).
7. Put the battery cover and fuse cover on.
