2015 Hyundai Sonata ground clearance

Safety system of your vehicle
In an angled collision, the force of
impact may direct the occupants in a
direction where the air bags would
not be able to provide any additional
benefit, and thus the sensors may
not deploy any air bags.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 "under-
ride" situation because deceleration
forces that are detected by sensors
may be significantly reduced by such
“underride” collisions.Front air bags may not inflate in
rollover accidents because front air
bag deployment would not provide
additional occupant protection.

What to do in an emergency
When driving with the compact spare
tyre mounted to your vehicle:
• Check the tyre pressure after
installing the compact spare tyre.
The compact spare tyre should be
inflated to 420 kPa (60 psi).
• Do not take this vehicle through an
automatic car wash whilst the com-
pact spare tyre is installed.
• Do not use the compact spare tyre
on any other vehicle because this
tyre has been designed especially
for your vehicle.
• The compact spare tyre’s tread life
is shorter than a regular tyre.
Inspect your compact spare tyre
regularly and replace worn com-
pact spare tyres with the same size
and design, mounted on the same
wheel.
• Do not use more than one compact
spare tyre at a time.
• Do not tow a trailer whilst the com-
pact spare tyre is installed.When the original tyre and wheel
are repaired and reinstalled on the
vehicle, the nut torque must be set
correctly. The correct nut tighten-
ing torque is 9-11 kg.m (65-79
lb.ft).
NOTICE
To prevent damaging the com-
pact spare tyre and your vehi-
cle:
•Drive slowly enough for the
road conditions to avoid all
hazards, such as a potholes
or debris.
•Avoid driving over obstacles.
The compact spare tyre diam-
eter is smaller than the diame-
ter of a conventional tyre and
reduces the ground clearance
approximately 25 mm (1 inch).
•Do not use tyre chains on the
compact spare tyre. Because
of the smaller size, a tyre
chain will not fit properly.
•Do not use the compact spare
tyre on any other wheels, nor
should standard tyres, snow
tyres, wheel covers or trim
rings be used with the com-
pact spare wheel.

Maintenance
Compact spare tyre replace-
ment (if equipped)
A compact spare tyre has a shorter
tread life than a regular size tyre.
Replace it when you can see the
tread wear indicator bars on the tyre.
The replacement compact spare tyre
should be the same size and design
as the one provided with your new
vehicle and should be mounted on
the same compact spare tyre wheel.
The compact spare tyre is not
designed to be mounted on a regular
size wheel, and the compact spare
tyre wheel is not designed for mount-
ing a regular size tyre. (Continued)•The use of any other tyre size
or type may seriously affect
ride, handling, ground clear-
ance, stopping distance, body
to tyre clearance, snow tyre
clearance, and speedometer
reliability.
•It is best to replace all four
tyres at the same time. If that
is not possible, or necessary,
then replace the two front or
two rear tyres as a pair.
Replacing just one tyre can
seriously affect your vehicle’s
handling.
•The ABS works by comparing
the speed of the wheels. Tyre
size can affect wheel speed.
When replacing tyres, all four
tyres must use the same size
originally supplied with the
vehicle. Using tyres of a dif-
ferent size can cause the ABS
(Anti-lock Brake System) and
ESC (Electronic Stability
Control) (if equipped) to work
irregularly.
•Driving on worn-out tyres is
very hazardous and will
reduce braking effectiveness,
steering accuracy, and trac-
tion.
•Your vehicle is equipped with
tyres designed to provide for
safe ride and handling capa-
bility. Do not use a size and
type of tyre and wheel that is
different from the one that is
originally installed on your
vehicle. It can affect the safety
and performance of your vehi-
cle, which could lead to han-
dling failure or rollover and
serious injury. When replacing
the tyres, be sure to equip all
four tyres with the tyre and
wheel of the same size, type,
tread, brand and load-carrying
capacity.

Maintenance
Wheel replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
Tyre traction
Tyre traction can be reduced if you
drive on worn tyres, tyres that are
improperly inflated or on slippery
road surfaces. Tyres should be
replaced when tread wear indicators
appear. To reduce the possibility of
losing control, slow down whenever
there is rain, snow or ice on the road.
Tyre maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tyre wear. If you find a tyre is worn
unevenly, have your dealer check the
wheel alignment.
When you have new tyres installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tyre life. Additionally, a tyre should
always be rebalanced if it is removed
from the wheel.
Tyre sidewall labeling
This information identifies and
describes the fundamental charac-
teristics of the tyre and also provides
the tyre identification number (TIN)
for safety standard certification. The
TIN can be used to identify the tyre in
case of a recall.

A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling
characteristics, ground clear-
ance, body-to-tyre clearance,
snow chain clearance,
speedometer and odometer cal-
ibration, headlamp aim and
bumper height.
