Driving your vehicle
Driving with wheels and tires with
different sizes may cause the ESC
system to malfunction. Before
replacing tires, make sure all four
tires and wheels are the same
size. Never drive the vehicle with
different sized tires and wheels
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 while driving, press
the ESC OFF button while driving on
a flat road surface.To prevent damage to the trans-
mission:
Do not allow wheel(s) of one
axle to spin excessively while
the ESC, ABS, and parking brake
warning lights are displayed.
The repairs would not be cov-
ered by the vehicle warranty.
Reduce engine power and do
not spin the wheel(s) excessive-
ly while 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.

Hill-Start Assist Control (HAC)
The Hill-Start Assist Control (HAC)
helps prevent the vehicle from rolling
backwards when starting a vehicle
from a stop on a hill. The system
operates the brakes automatically for
approximately 2 seconds and releas-
es the brake after 2 seconds or when
the accelerator pedal is depressed.
The HAC does not operate when
the shift lever is in P (Park) or N
(Neutral)
The HAC activates even though
the ESC (Electronic Stability
Control) is off but does not acti-
vate when the ESC has malfunc-
tioned.
Downhill Brake Control (DBC)
The Downhill Brake Control (DBC)
feature assists the driver to descend
down a steep hill without having to
depress the brake pedal.
NOTICE
If ESC indicator light ( ) or EPS
warning light ( ) stays on, your
vehicle may have a malfunction
with the VSM system. When the
warning light illuminates, have
your vehicle checked by an
authorized HYUNDAI dealer as
soon as possible.

road.
Emergency precautions
Tires
Do not use a tire and wheel package
with a different size and type from
the one originally installed on your
vehicle. It can affect the safety and
performance of your vehicle, which
could lead to steering failure or
rollover causing serious injury.
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. If
you equip your vehicle with any
tire/wheel combination not recom-
mended by HYUNDAI for off-road
driving, you should not use these
tires for highway driving.
Towing
AWD vehicles must be towed with a
wheel lift and dollies or flatbed equip-
ment with all the wheels off the
ground.
For more details, refer to "Towing"
in chapter 6.
Dynamometer testing
A full-time AWD vehicle must be test-
ed on a special four wheel chassis
dynamometer.OTLE055003
Do not grab the inside of the
steering wheel when you are
driving off-road. You may hurt
your arm by a sudden steering
maneuver or from steering wheel
rebound due to an impact with
objects on the ground. You could
lose control of the steering wheel
which may lead to serious injury
or death.
WARNING
Never start or run the engine
while a full-time AWD vehicle is
raised on a jack. The vehicle can
slip or roll off of a jack causing
serious injury or death to you or
those nearby.

The severe weather conditions of
winter quickly wear out tires and
cause other problems. To minimize
winter driving problems, you should
take the following suggestions:
Snow or Icy Conditions
You need to keep sufficient distance
between your vehicle and the vehicle
in front of you.
Apply the brakes gently. Speeding,
rapid acceleration, sudden brake
applications, and sharp turns are
potentially very hazardous practices.
During deceleration, use engine
braking to the fullest extent. Sudden
brake applications on snowy or icy
roads may cause the vehicle to skid.
To drive your vehicle in deep snow, it
may be necessary to use snow tires
or to install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to
carry include tire chains, tow straps
or chains, a flashlight, emergency
flares, sand, a shovel, jumper cables,
a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.
Snow tires
If you mount snow tires on your vehi-
cle, make sure to use radial tires of
the same size and load range as the
original tires. Mount snow tires on all
four wheels to balance your vehicle’s
handling in all weather conditions.
The traction provided by snow tires
on dry roads may not be as high as
your vehicle's original equipment
tires. Check with the tire dealer for
maximum speed recommendations.
Information
Do not install studded tires without
first checking local, state and munici-
pal regulations for possible restric-
tions against their use.
Tire chains
Since the sidewalls of radial tires are
thinner than other types of tires, they
may be damaged by mounting some
types of tire chains on them.
Therefore, the use of snow tires is
recommended instead of tire chains.
Do not mount tire chains on vehicles
equipped with aluminum wheels; if
unavoidable use a wire type chain. If
tire chains must be used, use gen-
uine HYUNDAI parts and install the
tire chain after reviewing the instruc-
tions provided with the tire chains.
Damage to your vehicle caused by
improper tire chain use is not cov-
ered by your vehicle manufacturer's
warranty.
i
Snow tires should be equivalent
in size and type to the vehicle’s
standard tires. Otherwise, the
safety and handling of your
vehicle may be adversely affect-
ed.
WARNING
OTLE058036

5-128
Driving your vehicle
- When using tire chains:
Wrong size chains or improperly
installed chains can damage
your vehicle's brake lines, sus-
pension, body and wheels.
Use SAE "S" class or wire
chains.
If you hear noise caused by
chains contacting the body,
retighten the chain to prevent
contact with the vehicle body.
To prevent body damage,
retighten the chains after driving
0.3~0.6 miles (0.5~1.0 km).
Do not use tire chains on vehi-
cles equipped with aluminum
wheels. If unavoidable, use a
wire type chain.
Use wire chains less than 0.59
inch (15 mm) wide to prevent
damage to the chain’s connec-
tion.
Winter Precautions
Use high quality ethylene glycol
coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Change to "winter weight" oil if
necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 7. The level of charge in
your battery can be checked by an
authorized HYUNDAI dealer or a
service station.

Tire Pressure Monitoring
System
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If
your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for
those tires.)As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the
tire to overheat and can lead to tire
failure.
Under-inflation also reduces fuel effi-
ciency and tire tread life, and may
affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver's responsi-
bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
telltale.Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS mal-
function indicator is combined with
the low tire pressure telltale. When
the system detects a malfunction,
the telltale will flash for approximate-
ly one minute and then remain con-
tinuously illuminated. This sequence
will continue upon subsequent vehi-
cle start-ups as long as the malfunc-
tion exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire pres-
sure as intended. TPMS malfunc-
tions may occur for a variety of rea-
sons, including the installation of
replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or alter-
nate tires and wheels allow the
TPMS to continue to function proper-
ly. Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure that
may cause loss of vehicle con-
trol resulting in an accident.

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.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 com-
pact 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 com-
pact 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.When the original tire and wheel
are repaired and reinstalled on the
vehicle, the lug nut torque must be
set correctly. The correct lug nut
tightening torque is 79~94 lbf·ft
(11~13 kgf·m).
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.
WARNING

What to do in an emergency
Jack label
To prevent damaging the com-
pact 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 diame-
ter is smaller than the diame-
ter of a conventional tire and
reduces the ground clearance
approximately 1 inch (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 com-
pact spare wheel.
CAUTION
The actual Jack label in the vehicle may differ from the illustration.
For more detailed specifications, refer to the label attached to the jack.

Tire Care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
All specifications (sizes and pres-
sures) can be found on a label
attached to the driver's side center
pillar.Replace tires that are worn,
show uneven wear, or are dam-
aged. Worn tires can cause
loss of braking effectiveness,
steering) control, or traction.
ALWAYS replace tires with the
same size as each tire that
was originally supplied with
this vehicle. Using tires and
wheels other than the recom-
mended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle's Anti-Lock Brake System
(ABS) resulting in a serious
accident.
Tire failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of
SERIOUS INJURY or DEATH,
take the following precautions:
Inspect your tires monthly for
proper inflation as well as
wear and damage.
The recommended cold tire
pressure for your vehicle can
be found in this manual and on
the tire label located on the dri-
ver's side center pillar. Always
use a tire pressure gauge to
measure tire pressure. Tires
with too much or too little
pressure wear unevenly caus-
ing poor handling.
Check the pressure of the
spare every time you check
the pressure of the other tires
on your vehicle.
WARNING

Maintenance
Tire Replacement
If the tire is worn evenly, a tread wear
indicator will appear as a solid band
across the tread. This shows there is
less than 1/16 inch (1.6 mm) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.
OLMB073027
Tread wear indicatorTo reduce the risk of DEATH or
SERIOUS INJURY:
Replace tires that are worn,
show uneven wear, or are
damaged. Worn tires can
cause loss of braking effec-
tiveness, steering control, and
traction.
Always replace tires with the
same size as each tire that
was originally supplied with
this vehicle. Using tires and
wheels other than the recom-
mended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle’s Anti-Lock Brake System
(ABS) resulting in a serious
accident.
WARNING When replacing tires (or
wheels), it is recommended to
replace the two front or two
rear tires (or wheels) as a pair.
Replacing just one tire can
seriously affect your vehicle's
handling.
Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, HYUNDAI recommends
that tires be replaced after six
(6) years of normal service.
Heat caused by hot climates or
frequent high loading condi-
tions can accelerate the aging
process. Failure to follow this
warning may cause sudden
tire failure, which could lead to
a loss of vehicle control result-
ing in an accident.
