Driving Your Vehicle
6-22
Driving on hills
B6003204
When coasting uphill or downhill, the
front sensors may not detect the vehicle
ahead or suddenly detect the vehicle
ahead at the end of the incline or at the
point where the incline changes. The
regenerative braking intensity is adjusted
automatically changing your vehicle
speed. Brake as needed to reduce your
driving speed.
Changing lanes
B6003205
• When a vehicle moves into your lane from an adjacent lane, it cannot be
detected by the sensors until it is in the
sensor's detection range.
• The smart regeneration system may not immediately detect the vehicle when
your vehicle changes lanes abruptly.
Braking System
Power-Assist Brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event of a vehicle power failure, the
power assist for the brakes will not work.
You can still stop your vehicle, but it will
require greater force and increased pedal
travel than normal. The stopping
distance, however, will be longer than
with power brakes.
Information • When the brake pedal is depressed under certain driving conditions or weather
conditions, you may temporarily hear a
noise. This is normal and does not indicate
a problem with your brakes.
• While driving on a road with deicing chemicals, brake noise or abnormal tire
wear may occur due to deicing chemicals.
In a safe traffic condition, additionally
apply the brakes to remove deicing
chemicals on the brake discs and pads.

WARNING Take the following precautions:
• Do not drive with your foot resting on the brake pedal. This will create
abnormal high brake temperatures,
excessive brake lining and pad wear,
and increased stopping distances. So
increase the regeneration braking level
with the left paddle shifter to decrease
the speed.
• When descending down a long or steep hill, use the paddle shifter to increase
the regeneration braking level in order
to decrease your speed without using
the brake pedal excessively. Applying
the brakes continuously will cause the
Hyundai_CE_en_US.book Page 22

brakes to overheat and could result in a
temporary loss of braking performance.
• Wet brakes may impair the vehicle's ability to safely decelerate. Because
wet brakes increase braking distance
and cause noise troubles, select 0 step
of the regenerative braking system and
depress the brake pedal around 10
times, with keeping the safe distance
from other vehicles, lightly in order to
dry the braking system. Such
procedure may decrease the driving
distance by restraining the
regenerative braking system, which is
not a system malfunction. Inspect the
braking system after car wash or
driving over wet road conditions.

Disc Brakes Wear Indicator
When your brake pads are worn and new
pads are required, you will hear a high
pitched warning sound from your front or
rear brakes. You may hear this sound
come and go or it may occur whenever
you depress the brake pedal.

Information Always replace brake pads as complete front
or rear axle sets.

WARNING Frequent braking may deform
components and worn the disc brake
causing vibration when braking. Observe
the speed limit to prevent brake damage
from excessive braking.
Brake wear, noise, vibration from
excessive braking or deformation of the
brakes caused by repeatedly braking in
high speed, racing on tracks, etc. can be
excluded from warranty coverage.

Explanation of Scheduled
Maintenance Items
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 maintenance
schedule.
Gear Fluid
The gear fluid should be inspected and
replaced according to the intervals
specified in the maintenance schedule.
Brake Hoses and Lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake Fluid
Check the 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 conforming to DOT 4
specification.
Brake Discs, Pads, Calipers
and Rotors
Check the pads, the discs, and the rotors
for any excessive wear-out. Inspect
calipers for any fluid leakage.
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 vehicle
off, check for excessive free-play in the
steering wheel. Check the linkage for
bends or damage. 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.

Check Tire Inflation Pressure
Check your tires, including the spare
tire, once a month or more.
How to check
Use a good quality tire pressure
gauge to check tire pressure. You can
not tell if your tires are properly
inflated simply by looking at them.
Radial tires may look properly inflated
when they are under-inflated.
Remove the valve cap from the tire
valve stem. Press the tire gauge
firmly onto the valve to get a pressure
measurement. If the cold tire inflation
pressure matches the recommended
pressure on the tire and loading
information label, no further
adjustment is necessary. If the
pressure is low, add air until you
reach the recommended pressure.
Make sure to put the valve caps back
on the valve stems. Without the valve
cap, dirt or moisture could get into
the valve core and cause air leakage.
If a valve cap is missing, install a new
one as soon as possible.
If you overfill the tire, release air by
pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gauge. Be
sure to put the valve caps back on the
valve stems. Without the valve cap,
dirt or moisture could get into the
valve core and cause air leakage. If a
valve cap is missing, install a new one
as soon as possible.
Tire Rotation
To equalize tread wear, HYUNDAI
recommends that the tires be rotated
according to the maintenance
schedule or sooner if irregular wear
develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire
pressure, improper wheel alignment,
out-of-balance wheels, severe
braking or severe cornering. Look for
bumps or bulges in the tread or side
of the tire. Replace the tire if you find
any of these conditions. Replace the
tire if fabric or cord is visible. After
rotation, be sure to bring the front
and rear tire pressures to
specification and check wheel lug nut
tightness (proper torque is 79-94
lbf·ft (11-13kgf·m).
B9005001
Disc brake pads should be inspected
for wear whenever tires are rotated.
Information When installing an unsymmetrical tire,
install the side marked “outside” facing
out.
