2018 INFINITI Q70 HYBRID service

1-50Safety — Seats, seat belts and supplemental restraint system
should not be used on the preten-
sioner system.
. If you need to dispose of the preten-
sioner or scrap the vehicle, it is
recommended you visit an INFINITI
retailer for this service. Correct pre-
tensioner disposal procedures are set
forth in the appropriate INFINITI
Service Manual. Incorrect disposal
procedures could cause personal in-
jury.
The pretensioner system may activate with
the supplemental air bag system in certain
types of collisions. Working with the seat
belt retractor, it helps tighten the seat belt
when the vehicle becomes involved in certain
types of collisions, helping to restrain front
seat occupants.
The pretensioner is encased with the seat
belt retractor. These seat belts are used the
same way as conventional seat belts.
When a pretensioner seat belt activates,
smoke is released and a loud noise may be
heard. The smoke is not harmful, and it does
not indicate a fire. Care should be taken not
to inhale it as it may cause irritation and
choking. Those with a history of a breathing
condition should get fresh air promptly.
After pretensioner activation, load limiters
allow the seat belt to release webbing (if necessary) to reduce forces against the
chest.
The supplemental air bag warning light
is used to indicate malfunctions in the
pretensioner system. See “Supplemental air
bag warning light” (P.1-51). If the operation
of the supplemental air bag warning light
illuminates, have the system checked. It is
recommended you visit an INFINITI retailer
for this service.
When selling your vehicle, we request that
you inform the buyer about the seat belt
pretensioners and guide the buyer to the
appropriate sections in this Owner’s Manual.

SUPPLEMENTAL AIR BAG
WARNING LIGHT
The supplemental air bag warning light,
displayingin the instrument panel,
monitors the circuits for the air bag systems,
pretensioners and all related wiring.
When the ignition switch is in the ON
position, the supplemental air bag warning
light illuminates for about 7 seconds and
then turns off. This means the SRS air bag
systems are operational.
If any of the following conditions occur, the
air bags and/or pretensioner systems need
servicing: .
The supplemental air bag warning light
remains on after approximately 7 sec-
onds.
. The supplemental air bag warning light
flashes intermittently.
. The supplemental air bag warning light
does not come on at all.
Under these conditions, the air bags and/or
pretensioner systems may not operate prop-
erly. They must be checked and repaired. It is
recommended you visit an INFINITI retailer
for this service.
WARNING
If the supplemental air bag warning light
is on, it could mean that the air bags
and/or pretensioner systems will not
operate in an accident. To help avoid
injury to yourself or others, have your
vehicle checked. It is recommended you
visit an INFINITI retailer for this service
as soon as possible.

recommended you visit an INFINITI retailer
for this service.
When the Hybrid EPS warning light illumi-
nates with the hybrid system running, the
power assist to the steering will cease
operation but you will still have control of
the vehicle. At this time, greater steering
efforts are required to operate the steering
wheel, especially in sharp turns and at low
speeds. However, if the steering wheel
operation is still performed, the Hybrid EPS
may stop and the Hybrid EPS warning light
will illuminate. Place the ignition switch in
the OFF position. For a while after it refrains
from the steering wheel control, the tem-
perature of the Hybrid EPS system will go
