Good braking practices
WARNING
Whenever leaving the vehicle or
parking, always come to a complete
stop and continue to depress the brake
pedal. Shift the gear to the P (Park)
position, then apply the parking brake,
and press the Engine Start/Stop button
to the OFF position.
Vehicles parked with the parking brake
not applied or not fully engaged may
roll inadvertently and may cause injury
to the driver and others. ALWAYS apply
the parking brake before exiting the
vehicle.
Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle will not stop as
quickly if the brakes are wet. Wet brakes
may cause the vehicle to pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns to
normal. If the braking action does not
return to normal, stop as soon as it is safe
to do so and call an authorized HYUNDAI
dealer for assistance.
DO NOT drive with your foot resting on
the brake pedal. Even light, but constant
pedal pressure can result in the brakes
overheating, brake wear, and possibly
even brake failure.
If a tire goes flat while you are driving,
apply the brakes gently and keep the
vehicle pointed straight ahead while you
slow down. When you are moving slowly
enough for it to be safe to do so, pull off
the road and stop in a safe location.
Keep your foot firmly on the brake pedal
when the vehicle is stopped to prevent
the vehicle from rolling forward.

Four Wheel Drive (4WD) delivers engine
power to front and rear wheels for
maximum traction. 4WD is useful when
extra traction is required, such as when
driving on, muddy, wet, or snow-covered
roads.
WARNING
To reduce the risk of SERIOUS INJURY
or DEATH:
Do not drive in conditions that
exceed the vehicles intended
design such as challenging off-road
conditions.
Avoid high speeds when cornering or
turning.
Do not make quick steering wheel
movements, such as sharp lane
changes or fast, sharp turns.
The risk of a rollover is greatly
increased if you lose control of your
vehicle at highway speeds.
Loss of control often occurs if two or
more wheels drop off the roadway
and the driver over steers to reenter
the roadway.
In the event your vehicle leaves
the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
NOTICE
Do not drive in water if the level
is higher than the bottom of the
vehicle.
Check your brake condition once
you are out of mud or water. Depress
the brake pedal several times as you
move slowly until you feel normal
braking return.
Shorten your scheduled
maintenance interval if you drive in
off-road conditions such as sand,
mud or water (see "Maintenance
Under Severe Usage Conditions"
section in chapter 9).
Always wash your vehicle thoroughly
after off road use, especially the
bottom of the vehicle.
Be sure to equip the vehicle with four
tires of the same size and type.
Make sure that a full time 4WD
vehicle is towed by a flat bed tow
truck.

CAUTION
When driving on normal roads,
deactivate the 4WD LOCK mode by
pushing the 4WD LOCK button (4WD
LOCK indicator light goes off). Driving
on normal roads with the 4WD LOCK
mode, especially, when cornering
may cause mechanical noise or
vibration. The noise and vibration will
disappear when the 4WD LOCK mode is
deactivated. Prolonged driving with the
noise and vibration may damage some
parts of the power train.
NOTICE
When the 4WD LOCK mode is
deactivated, a sensation may be felt
as the driving power is delivered
entirely to the front wheels.
For safe 4WD operation
Make sure all passengers are wearing
seat belts.
Sit upright and closer to the steering
wheel than usual. Adjust the steering
wheel to a position comfortable for
you to drive.
Start off slowly by applying the
accelerator pedal gently.
Use snow tires or tire chains.
Keep sufficient distance between your
vehicle and the vehicle in front of you.
Apply engine braking during
deceleration by using the paddle
shifter (manual shift mode) and
manually selecting a lower gear.
Avoid speeding, rapid acceleration,
sudden brake applications, and sharp
turns to prevent skids.

Maintain slow and constant speed.
Operate the accelerator pedal slowly
to ensure safe driving (wheel-slip
prevention).
Keep sufficient distance between your
vehicle and the vehicle in front of you.
Reduce vehicle speed and always
check the road condition.
Avoid speeding, rapid acceleration,
sudden brake applications, and sharp
turns to prevent getting stuck.
When the vehicle is stuck in snow,
sand or mud, the tires may not
operate.
This is to protect the transmission and
not a malfunction.
CAUTION
When the vehicle is stuck in snow, sand
or mud, place a non-slip material under
the drive wheels to provide traction
OR slowly spin the wheels in forward
and reverse directions which causes
a rocking motion that may free the
vehicle. However, avoid running the
engine continuously at high rpm, doing
so may damage the 4WD system.

Driving uphill
- Before starting off, check if it is
possible to drive uphill.
- Drive as straight as possible.
Driving downhill
- Do not change gear while driving
downhill. Select gear before driving
downhill.
- Drive slowly using engine braking
while driving downhill.
- Drive straight as possible.
WARNING
Exercise extreme caution driving up or
down steep hills. The vehicle may flip
over depending on the grade, terrain,
water and mud conditions.

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 recommended by HYUNDAI for off-
road driving, you should not use these
tires for highway driving.
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.
Towing
4WD vehicles must be towed with
a wheel lift and dollies or flatbed
equipment with all the wheels off the
ground. For more details, refer to
"Towing" section in chapter 8.
Dynamometer testing
An 4WD vehicle must be tested on a
special four wheel chassis dynamometer.
OOS057009
[A] : Roll tester (Speedometer),
[B] : Temporary free roller
An 4WD vehicle should not be tested
on a 2WD roll tester. If a 2WD roll tester
must be used, perform the following
procedure:
1. Check the tire pressures
recommended for your vehicle.
2. Place the rear wheels on the roll tester
for a speedometer test as shown in
the illustration.
3. Release the parking brake.
4. Place the front wheels on the
temporary free roller as shown in the
illustration.
CAUTION
Never engage the parking brake
while performing the test.
When the vehicle is lifted up, do not
operate the front and rear wheel
separately. All four wheels should be
operated.

by the ISG system, some warning lights
(ABS, ESC, ESC OFF, EPS or Parking
brake warning light) may turn on for a
few seconds. This happens because of
low battery voltage. It does not mean
the system is malfunctioning.
