2023 GENESIS G90 ground clearance

3-77
03
ORS031082L
Just before impact, drivers often brake
heavily. Such heavy braking lowers the
front portion of the vehicle causing it
to “ride” under a vehicle with a higher
ground clearance. Air bags may not
inflate in this “underride” situation
because deceleration forces that are
detected by sensors may be significantly
reduced by such “underride” collisions.
ORS031083
Front air bags may not inflate in
rollover accidents because front air bag
deployment would not provide additional
occupant protection.
Information
With rollover sensor
The side and curtain air bags and the
front center side air bag may inflate in a
rollover situation, when it is detected by
the rollover sensor.
ORS031084L
Air bags may not inflate if the vehicle
collides with objects such as utility poles
or trees, where the point of impact is
concentrated and the collision energy is
absorbed by the vehicle structure.

In the following cases, some vehicles,
pedestrians or animals in your lane

- Vehicles offset to one side
- Slow-moving vehicles or sudden-
decelerating vehicles
- Vehicles with higher ground
clearance or vehicles carrying loads
that stick out of the back of the
vehicle
- Vehicles that has the front lifted
dueto heavy loads

(2m) from your vehicle
- Oncoming vehicles
- Stopped vehicles - Vehicles with small rear profile, such
as trailers
- Narrow vehicles, such as

Emergency Situations
When driving with the compact spare tire
mounted to your vehicle:
• Check the tire pressure after installing
the compact spare tire. The compact
spare tire should be inflated to 60 psi
(420 kPa).
• Do not take this vehicle through
an automatic car wash while the
compact spare tire is installed.
• Do not use the compact spare tire on
any other vehicle because this tire
has been designed especially for your
vehicle.
• The compact spare tire’s tread life is
shorter than a regular tire. Inspect
your compact spare tire regularly and
replace worn compact spare tires with
the same size and design, mounted on
the same wheel.
• Do not use more than one compact
spare tire at a time.
• Do not tow a trailer while the compact
spare tire is installed.
Information
When the original tire and wheel are
repaired and reinstalled on the vehicle, the
wheel bolt torque must be set correctly.
The correct wheel bolt tightening torque is
101~116 lbf·ft (14~16 kgf·m).
NOTICE
To prevent damaging the compact
spare tire and your vehicle:
• Drive slowly enough for the road
conditions to avoid all hazards, such
as a potholes or debris.
• Avoid driving over obstacles. The
compact spare tire diameter is
smaller than the diameter of a
conventional tire and reduces the
ground clearance approximately
1 in. (25 mm).
• Do not use tire chains on the
compact spare tire. Because of the
smaller size, a tire chain will not fit
properly.
• Do not use the compact spare tire
on any other wheels, nor should
standard tires, snow tires, wheel
covers or trim rings be used with the
compact spare wheel.
• Do not suddenly accelerate or
decelerate 0 ~ 25 mph (0 ~ 40 km/h)
in any driving mode. It may cause
leakage of transfer oil.
