2014 INFINITI Q50 HYBRID jacking

maintaining the correct air pressure and
visually inspect the tires for wear and
damage. See“Wheels and tires” (P.8-30) of
this manual.
If a tire rapidly loses air pressure or
“blows-out” while driving maintain control
of the vehicle by following the procedure
below. Please note that this procedure is
only a general guide. The vehicle must be
driven as appropriate based on the condi-
tions of the vehicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pressure.
Losing control of the vehicle may cause a
collision and result in personal injury.
. The vehicle generally moves or pulls in
the direction of the flat tire.
. Do not rapidly apply the brakes.
. Do not rapidly release the accelerator
pedal.
. Do not rapidly turn the steering wheel.
1. Remain calm and do not overreact. 2. Maintain a firm grip on the steering
wheel with both hands and try to hold a
straight course.
3. When appropriate, slowly release the accelerator pedal to gradually slow the
vehicle.
4. Gradually steer the vehicle to a safe location off the road and away from
traffic if possible.
5. Lightly apply the brake pedal to gradu- ally stop the vehicle.
6. Turn on the hazard warning flashers and either contact a roadside emer-
gency service to change the tire or see
“Jacking up the vehicle and replacing
tires” (P.8-40) of this Owner’s Manual.
DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alcohol or
drugs. Alcohol in the bloodstream reduces
coordination, delays reaction time and im-
pairs judgement. Driving after drinking
alcohol increases the likelihood of being
involved in an accident injuring yourself and others. Additionally, if you are injured in an
accident, alcohol can increase the severity
of the injury.
INFINITI is committed to safe driving.
However, you must choose not to drive
under the influence of alcohol. Every year
thousands of people are injured or killed in
alcohol-related accidents. Although the
local laws vary on what is considered to
be legally intoxicated, the fact is that
alcohol affects all people differently and
most people underestimate the effects of
alcohol.
Remember, drinking and driving don’t mix!
And that is true for drugs, too (over-the-
counter, prescription, and illegal drugs).
Don’t drive if your ability to operate your
vehicle is impaired by alcohol, drugs, or
some other physical condition.
Starting and driving5-9

6-4In case of emergency
.Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
. Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.
RUN-FLAT TIRES
Run-flat tires are those tires that can be
used temporarily if they are punctured. See
“Run-flat tires” (P.8-36).
Also, refer to “Important Tire Safety In-
formation” (US) or“Tire Safety Informa-
tion” (Canada) in the INFINITI Warranty
Information Booklet.
WARNING
. Although you can continue driving with a
punctured run-flat tire, remember that
vehicle handling stability is reduced,
which could lead to an accident and
personal injury. Also, driving a long
distance at high speeds may damage
the tires. .
Do not drive at speeds above 50 MPH
(80 km/h) and do not drive more than
approximately 93 miles (150 km) with a
punctured run-flat tire. The actual dis-
tance the vehicle can be driven on a flat
tire depends on outside temperature,
vehicle load, road conditions and other
factors.
. Drive safely at reduced speeds. Avoid
hard cornering or braking, which may
cause you to lose control of the vehicle.
. If you detect any unusual sounds or
vibrations while driving with a punctured
run-flat tire, pull off the road to a safe
location and stop the vehicle as soon as
possible. The tire may be seriously
damaged and need to be replaced.CAUTION
.Never install tire chains on a punctured
run-flat tire, as this could damage your
vehicle.
. Avoid driving over any projection or
pothole, as the clearance between the
vehicle and the ground is smaller than
normal. .
Do not enter an automated car wash with
a punctured run-flat tire.
. Have the punctured tire inspected by an
INFINITI retailer or other authorized
repair shop. Replace the tire as soon
as possible if the tire is seriously
damaged.
If you have a flat tire and have to stop the
vehicle, follow the instructions below.
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 shift lever to
the P (Park) position.
4. Turn off the hybrid system.
5. Raise the hood to warn other traffic, and to signal professional road assis-
tance personnel that you need assis-
tance.
6. Have all passengers get out of the vehicle and stand in a safe place, away
from traffic and clear of the vehicle.
For the tire removing procedure, see
“Jacking up the vehicle and replacing tires”
(P.8-40).

CHANGING WHEELS AND TIRES
Tire rotation
INFINITI recommends rotating the
tires every 5,000 miles (8,000 km).
(See“Jacking up the vehicle and
replacing tires” (P.8-40) for tire re-
placing procedures.)
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 the specification at all
times. It is recommended that wheel
nuts be tightened to the specifica-
tion at each tire rotation interval.
WARNING
.
After rotating the tires, check and
adjust the tire pressure.
. Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information ”(US) or “Tire
Safety Information ”(Canada) in
the Warranty Information Booklet.

ence with the brake discs/drums. Such
interference can lead to decreased brak-
ing efficiency and/or early brake pad/
shoe wear. See“Wheels and tires” (P.9-
9) of this manual for wheel off-set
dimensions.
. When r a wheel is replaced, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately 1 minute. The light will
remain on after 1 minute. Contact your
INFINITI retailer as soon as possible for
tire replacement and/or system reset-
ting.
. Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
. Do not install a damaged or deformed
wheel or tire even if it has been repaired.
Such wheels or tires could have struc-
tural damage and could fail without
warning.
. The use of retread tire is not recom-
mended.
. For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or“Tire Safety Infor-
mation” (Canada) in the Warranty In- formation Booklet.
Intelligent All-Wheel Drive (AWD)
models
CAUTION
Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four wheels.
Failure to do so may result in a circumfer-
ence difference between tires on the front
and rear axles which will cause excessive
tire wear and may damage the transmission,
transfer case and differential gears.
If excessive tire wear is found, it is
recommended that all four tires be re-
placed with tires of the same size, brand,
construction and tread pattern. The tire
pressure and wheel alignment should also
be checked and corrected as necessary.
Contact an INFINITI retailer.
Wheel balance
Unbalanced wheels may affect vehicle
handling and tire life. Even with regular
use, wheels can get out of balance. There- fore, they should be balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
For additional information regarding tires,
refer to
“Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada)
in the INFINITI Warranty Information Book-
let.
Care of wheels
See “Cleaning exterior” (P.7-2) for details
about care of the wheels.
JACKING UP THE VEHICLE AND
REPLACING TIRES
Your vehicle is equipped with run-flat tires
and you can continue driving to a safe
location even if they are punctured. (See
“Run-flat tires” (P.6-4) and“Run-flat tires”
(P.8-36).)
This section contains the information
about the vehicle jack-up procedures and
the tire replacement.

close to your vehicle. Wait for profes-
sional road assistance.
MCE0001A
Blocking wheels
Place suitable blocks*1at 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.
Jacking up the vehicle and remov-
ing a 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 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 limited slip differen-
tials.
. Do not allow passengers to stay in the
vehicle while it is on the jack.
