2019 Hyundai Ioniq Electric wheel torque

5-34
Driving your vehicle
Driving with wheels and tyres with
different sizes may cause the ESC
system to malfunction. Before
replacing tyres, make sure all four
tyres and wheels are the same
size. Never drive the vehicle with
different sized wheels and tyres
installed.
ESC OFF usage
When Driving
The ESC OFF mode should only be
used briefly to help free the vehicle if
stuck in snow or mud, by temporarily
stopping operation of the ESC, to
maintain wheel torque.
To turn ESC off whilst driving, press
the ESC OFF button whilst driving on
a flat road surface. Do not allow wheel(s) of one
axle to spin excessively whilst
the ESC, ABS, and parking brake
warning lights are displayed.
The repairs would not be cov-
ered by the vehicle warranty.
Reduce vehicle power and do
not spin the wheel(s) excessive-
ly whilst these lights are dis-
played.
When operating the vehicle on a dynamometer, make sure the
ESC is turned off (ESC OFF light
illuminated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.

NOTICE
NOTICE
When the ESC is blinking, this
indicates the ESC is active:
Drive slowly and NEVER attempt
to accelerate. NEVER turn the
ESC off whilst the ESC indicator
light is blinking or you may lose
control of the vehicle resulting in
an accident.

Driving your vehicle
The Lane Keeping Assist (LKA) sys-
tem help detect lane markers on the
road with a camera at the front wind-
screen, and assists the driver's
steering to help keep the vehicle
between lanes.
When the system detects the vehicle
straying from its lane, it alerts the
driver with a visual and audiouble
warning, whilst applying a slight
counter-steering torque, trying to
prevent the vehicle from moving out
of its lane.

The Lane Keeping Assist (LKA)
system is not a substitute for
safe driving practices, but a
convenience function only. It is
the responsibility of the driver
to always be aware of the sur-
rounding and steer the vehicle.
WARNING
Take the following precautions
when using the Lane Keeping
Assist (LKA) system:
Do not steer the steering
wheel suddenly when the
steering wheel is being assist-
ed by the system.
LKA system helps to prevent
the driver from moving out of
the lane unintentionally by
assisting the driver's steering.
However, the driver should
not solely rely on the system
but always pay attention on
the steering wheel to stay in
the lane.

WARNING
(Continued)
The operation of the LKA sys-
tem can be cancelled or not
work properly according to
road condition and surround-
ings. Always be cautious
when driving.
Do not disassemble the LKA
system camera temporarily to
tint the window or attach any
types of coatings and acces-
sories. If you disassemble the
camera and assemble it again,
we recommend that you take
your vehicle to a HYUNDAI
authorised repairer and have
the system checked for cali-
bration.
When you replace the wind-
screen glass, LKA system
camera or related parts of the
steering wheel, we recom-
mend that you take your vehi-
cle to a HYUNDAI authorised
repairer and have the system
checked for calibration.(Continued)

Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Reduction gear fluid
The reduction gear fluid should be
inspected according to the intervals
specified in the maintenance sched-
ule.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake fluid
Check brake fluid level in the brake
fluid reservoir. The level should be
between the MIN and the MAX
marks on the side of the reservoir.
Use only hydraulic brake fluid con-
forming to DOT 3 or DOT 4 specifi-
cation.
Brake discs, pads, calipers
and rotors
Check the pads, the disc, and the
rotor for any excessive wear-out.
Inspect calipers for any fluid leakage.
For more information on checking
the pads or lining wear limit, refer to
the HYUNDAI web site.

vice.hyundai-motor.com)
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and the
hybrid system off, check for exces-
sive free-play in the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage.
Replace any damaged parts.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant
Check the air conditioning lines and
connections for leakage and damage.

Maintenance
Tyre rotation
To equalize tread wear, HYUNDAI
recommends that the tyres be rotat-
ed every 6,000 miles (10,000 km) or
sooner if irregular wear develops.
During rotation, check the tyres for
correct balance.
When rotating tyres, check for
uneven wear and damage. Abnormal
wear is usually caused by incorrect
tyre pressure, improper wheel align-
ment, out-of-balance wheels, severe
braking or severe cornering. Look for
bumps or bulges in the tread or side
of tyre. Replace the tyre if you find
either of these conditions. Replace
the tyre if fabric or cord is visible.
After rotation, be sure to bring the
front and rear tyre pressures to spec-
ification and check lug nut tightness
(proper torque is
11~13 kgf·m [79~94 lbf·ft]).Disc brake pads should be inspected
for wear whenever tyres are rotated.
Information
The outside and inside of the unsym-
metrical tyre is distinguishable. When
installing an unsymmetrical tyre, be
sure to install the side marked "out-
side" face the outside. If the side
marked "inside" is installed on the
outside, it will have a bad effect on
vehicle performance.

■ With a full-size spare tyre (if equipped)
■Without a spare tyre
Do not use the compact spare
tyre for tyre rotation.
Do not mix bias ply and radial
ply tyres under any circum-
stances. This may cause
unusual handling characteris-
tics that may cause loss of
vehicle control resulting in an
accident.

When replacing tyres, use the same size originally supplied with the vehicle.
Using tyres of a different size can damage the related parts or not work properly.
CAUTION
*1 : Normal load : Up to 3 persons
It is permissible to add 3 psi (20 kPa) to the standard tyre pressure specification if colder temperatures are expected soon. Tyres typically lose 1 psi (7 kPa) for every 7°C (12°F) temperature drop. If extreme temperature
variations are expected, recheck your tyre pressure as necessary to keep them properly inflated.
An air pressure generally decreases, as you drive up to a high-altitude area above sea level. Thus, if you plan to drive a high-altitude area, check the tyre pressures in advance. If necessary, inflate them to a proper level
(Air inflation per altitude: +2.4 psi/1 mile (+10 kPa/1 km).
