Emergency Precautions
Tires
When replacing the tires, be sure to
equip all four tires with the tire and
wheel of the same size, type, tread,
brand and load-carrying capacity.
In an emergency situation, a com-
pact spare tire may be used. But, do
not use the compact spare tire con-
tinuously. Repair or replace the origi-
nal tire as soon as possible to avoid
failure of the differential or AWD sys-
tem.
Exercise extreme caution driv-
ing up or down steep hills. The
vehicle may flip depending on
the grade, terrain and water/
mud conditions.
WARNING
Do not use tire and wheel with
different size and type from the
one originally installed on your
vehicle. It can affect the safety
and performance of your vehi-
cle, which could lead to steering
failure or rollover causing seri-
ous injury.
WARNING

6-20
What to do in an emergency
Your vehicle has metric threads
on the studs and lug nuts. Make
certain during tire changing that
the same nuts that were removed
are reinstalled. If you have to
replace your lug nuts make sure
they have metric threads to avoid
damaging the studs and ensure
the wheel is properly secured to
the hub. Consult an authorized
retailer of Genesis Branded prod-
ucts for assistance.
If any of the equipment such as the
jack, lug nuts, studs, or other equip-
ment is damaged or in poor condi-
tion, do not attempt to change the
tire and call for assistance.
Use of compact spare tires
Compact spare tires are designed for
emergency use only. Drive carefully
on the compact spare tire and
always follow the safety precautions.
NOTICE
To prevent compact spare tire
failure and loss of control pos-
sibly resulting in an accident:
Use the compact spare tire only in an emergency.
NEVER operate your vehicle over 50 mph (80 km/h).
Do not exceed the vehicle's maximum load rating or the
load carrying capacity shown
on the sidewall of the com-
pact spare tire.
Do not use the compact spare tire continuously. Repair or
replace the original tire as
soon as possible to avoid fail-
ure of the compact spare tire.
On AWD vehicles, do not use the compact spare tire contin-
uously. It may damage to the
AWD driving system or the
differential. Temporarily use
the compact spare tire for
emergency only.

*1: Refer to the recommended SAE viscosity numbers on the next page.
*2: Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel economy by reducing the amount of fuel
necessary to overcome engine friction. Often, these improvements are difficult to
measure in everyday driving, but in a year’s time, they can offer significant cost and
energy savings.
*
3: If the API SM & ILSAC GF-4 engine oil is not available in your country, you are able to use API SL & ILSAC GF-3
*
4: If the front/rear differential is submerged, we recommend that you visit an author- ized retailer of Genesis Branded products to replace differential oil.
