ORS081008LORS081008L
1. Park your vehicle in a safe location.
2. Connect the filling hose O of the
compressor directly to the tire valve.
3. Plug the compressor power cord into
the vehicle power outlet.
4. Adjust the tire inflation pressure to
the recommended tire inflation. With
the ignition switched on, proceed as
follows.
-To increase the inflation pressure:
Switch on the compressor. To
check the current inflation pressure
setting, briefly switch off the
compressor.
-To reduce the inflation pressure:
Press the button U on the
compressor.
NOTICE
Do not let the compressor run for more
than 10 minutes, otherwise the device
will overheat and may be damaged.
Information
• The pressure gauge may show
higher than actual reading when the
compressor is running. To get an
accurate tire reading, the compressor
needs to be turned off.
• When reinstalling the repaired or
replaced tire and wheel on the vehicle,
tighten the wheel bolt to 101~116 lbf·ft
(14~16 kgf·m).
CAUTION
Do not use the sealant when the tire
pressure only needs to be adjusted.
WARNING
The tire inflation pressure must be at
least 32 psi (220 kPa). If it is not, do not
continue driving.
Call for road side service or towing.

Maintenance
Operating precautions for catalytic
converters
WARNING
The exhaust system and catalytic
system are very hot while the engine is
running or immediately after the engine
is turned off. To avoid SERIOUS INJURY
or DEATH:

[Do not park, idle, or drive the vehicle
over or near flammable objects, such
as grass, vegetation, paper, leaves,
etc. A hot exhaust system can ignite
flammable items under your vehicle.

[Keep away from the exhaust system
and catalytic converter or you may
get burned.
Also, do not remove the heat sink
around the exhaust system, do not
seal the bottom of the vehicle, and
do not coat the vehicle for corrosion
control. It may present a fire risk
under certain conditions.
Your vehicle is equipped with a catalytic
converter emission control device.
To prevent damage to the catalytic
converter and to your vehicle, take the
following precautions:

[Use only UNLEADED FUEL for
gasoline engines.

[Do not operate the vehicle when
there are signs of engine malfunction,
such as misfire or a noticeable loss of
performance.

[Do not misuse or abuse the engine.
Examples of misuse are coasting with
the engine off and descending steep
grades in gear with the engine off.

[Do not operate the engine at high idle
speed for extended periods
(5 minutes or more).

[Do not modify or tamper with any
part of the engine or emission
control system. All inspections and
adjustments must be made by an
authorized retailer of Genesis Branded
products.

[Avoid driving with an extremely low
fuel level.
Running out of fuel could cause the
engine to misfire, damaging the
catalytic converter.
