Infiniti QX: Changing a flat tire
If you have a flat tire, follow the instructions below.
Stopping the vehicle
1. Safely move the vehicle off the road
and away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the
parking brake. Move the selector lever
to the P (Park) position.
4. Turn off the engine.
5. Raise the hood to warn other traffic,
and to signal professional road assistance
personnel that you need assistance.
6. Have all passengers get out of the
vehicle and stand in a safe place, away
from traffic and clear of the vehicle.
WARNING
► Make sure the parking brake is securely
applied and the automatic transmission
is in the P (Park) position.
► Never change tires when the vehicle is
on a slope, ice or slippery areas. This is
hazardous.
► Never change tires if oncoming traffic is
close to your vehicle. Wait for professional
road assistance.
Blocking wheels
Place suitable blocks 1 at both the front and back of the wheel diagonally opposite the flat tire to prevent the vehicle from moving when it is jacked up.
WARNING
Be sure to block the wheel as the vehicle
may move and result in personal injury.
Getting the spare tire and tools
1. Open the lift gate.
2. Raise the cargo floor board using the
handle A .
WARNING
When removing jacking tools, be sure the
rubber sound suppressor 1 , used to
control jack stand from rattling against
metal, is not attached to the jacking tool.
If rubber sound suppressor remains on jack when vehicle is being jacked up, the vehicle will be unstable and may fall off jack stand causing serious injury of death.
3. Remove the cargo floor cover.
4. Remove the jacking tools.
5. Securely screw to connect the T-shaped end of the jack rod and two extension bars 1 as illustrated. 6. Fit the square end of the jack rod into the square hole of the wheel nut wrench to form a handle 2 . 7. Locate the oval opening above the middle of the rear bumper. 8. Place the T-shaped end of the jack rod through the opening and direct it towards the spare wheel winch assembly, located directly above the spare wheel.
CAUTION
Do not insert the jack rod straight as it is
designed to be inserted at an angle as
shown.
9. Seat the T-shaped end of the jack rod into the T-shaped opening of the spare wheel winch. Apply pressure to keep the jack rod engaged in the spare wheel winch and turn the jack rod counterclockwise to lower the spare wheel.
10.Once the spare wheel is completely lowered, remove the jack rod and reach under the vehicle to remove the hanging plate. 11.Carefully slide the spare wheel from under the rear of the vehicle. After preparing the spare tire, to remove the rod, pull out the rod while moving the rod to the right and left with the screw of the extension facing the side.
CAUTION
When storing the wheel, make sure that the
hanging plate is in the center of the wheel
and then lift it up into the storage area.
CAUTION
When storing the wheel, be sure to mount
the wheel horizontally. Securing the wheel
that is in a tilted position as illustrated may
cause looseness and dropping of the wheel
while driving. Lower the wheel on the
ground again, and make sure that the
hanging plate is properly set. Hang the
wheel again and make sure that the wheel is
held horizontally, then store the wheel.
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 engine while
vehicle is on the jack, as it may cause
the vehicle to move. This is especially
true for vehicles with limited slip differentials.
► Do not allow passengers to stay in the
vehicle while it is on the jack.
Carefully read the caution label attached to
the jack body and the following instructions.
1. Place the jack directly under the jack-up points as illustrated. The jack should be used on level firm ground.
2. Loosen each wheel nut one or two turns by turning counterclockwise with the wheel nut wrench. Do not remove the wheel nuts until the tire is off the ground.
3. Install the assembled jack rod into the jack as shown. 4. Carefully raise the vehicle until the clearance between the tire and ground is achieved. 5. To lift the vehicle, securely hold the jack lever and rod with both hands and turn the jack lever.
NOTE:
Before jacking up the vehicle, make sure the ignition switch is placed in the OFF position. If the vehicle is lifted up with the engine running, the auto-leveling suspension will become disabled after 120 seconds. To reset the auto-leveling suspension, cycle the ignition switch ON/OFF one time.
Installing the spare tire
The full-size temporary use only spare tire (if so equipped) is designed for emergency use. (See specific instructions under the heading “Wheels and tires” in the “8. Maintenance and do-it-yourself” section.)
1. Clean any mud or dirt from the surface
between 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 as illustrated (1 , 2 , 3 ,
4 , 5 , 6 ) until they are tight.
4. Lower the vehicle slowly until the tire
touches the ground. Then, with the
wheel nut wrench, tighten the wheel
nuts securely in the sequence as
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:
98 ft-lb (133 N·m)
The wheel nuts must be kept tightened
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.
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 malfunction.
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 instructions
under the heading “Wheels and
tires” in the “8. Maintenance and do-ityourself”
section.)
