Driving with wheel and tire sizes dif-
ferent than original-equipment may
cause the ESC system to malfunc-
tion. Before replacing tires, make
sure all four tires and wheels are the
same as the original size. Never
drive the vehicle with different sized
tires and wheels installed.
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 gear is shifted to 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.
NOTICE
If the ESC indicator light ( ) or
MDPS warning light ( ) stays
on or blinks, your vehicle may
have a malfunction with the
VSM system. When the warning
light illuminates, have your vehi-
cle checked by an authorized
retailer of Genesis Branded
products as soon as possible.
WARNING
Always be ready to depress the
accelerator pedal when starting
off on a incline. The HAC acti-
vates only for approximately 2
seconds.
WARNING

Using All Wheel Drive (AWD)
The All Wheel Drive (AWD) system
delivers engine power to front and
rear wheels for maximum traction.
AWD is useful when extra traction is
required, such as when driving on,
muddy, wet, or snow-covered roads.
If the system determines there is a
need for four wheel drive, the
engine's driving power is distributed
to all four wheels automatically.

If the AWD warning light ( )
stays on the instrument cluster,
your vehicle may have a mal-
function with the AWD system.
When the AWD warning light
( ) illuminates have your
vehicle checked by an author-
ized retailer of Genesis Branded
products as soon as possible.
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 cor- nering or turning.
Do not make quick steering wheel movements, such as
sharp lane changes or fast,
sharp turns.
The risk of a rollover is great- ly increased if you lose con-
trol 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.
Always drive safely and use caution when driving an AWD
vehicle.
WARNING

Information
• Do not drive in water if the level ishigher than the bottom of the vehi-
cle.
• 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 mainte- nance interval if you drive in off-
road conditions such as sand, mud
or water (see "Maintenance Under
Severe Usage Conditions" in chap-
ter 7).
• Make sure that an AWD vehicle is towed by flatbed tow truck.
For safe AWD operation
Before driving
Make sure all passengers arewearing seat belts.
Sit upright and adjust the steering wheel to a position comfortable for
you to drive.
Driving on snow-covered or icy
roads
Start off slowly by applying theaccelerator pedal gently.
Use of snow tires is recommended. For more information on Snow
Tires refer to "Winter Driving" in
this chapter.
Keep sufficient distance between your vehicle and the vehicle in front
of you.
When approaching a stop sign or stop light, release the accelerator
pedal to provide engine braking
during deceleration.
Avoid speeding, rapid acceleration, sudden brake applications, and
sharp turns to prevent skids.

Driving your vehicle

Driving in sand or mud
Maintain slow and constant speed.
Keep sufficient distance betweenyour 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, avoid running the
engine continuously at high rpm,
doing so may damage the tires,
transmission, differential or AWD
system.
Information
• When using Snow Tires, mount them on all four wheels.
• When using AutoSock
®(fabric snow
chain), install them on all four tires.
However, if you are in a situation to
use only two AutoSock
®, install
them on the rear tires. In this case,
drive a short distance to prevent
damage to the AWD system.
For more information on Snow Tires
and Tire Chains, refer to "Winter
Driving" in this chapter.
Driving up or down hills
Driving uphill - Before starting off, check if it ispossible to drive uphill.
- Drive as straight as possible.
Driving downhill - Do not change gear while drivingdownhill. Select gear before driv-
ing downhill.
- Drive slowly and select Manual Shift Mode to provide engine
braking while driving downhill.
- Drive straight as possible.

the grade, terrain and water/
mud conditions.
WARNING

Emergency Precautions
Tires
When replacing the tires, be sure to
equip all four tires with the same
size, type, tread, brand and load-car-
rying capacity.
In an emergency situation, a com-
pact spare tire may be used. But, do
not use the compact spare tire con-
tinuously. Repair or replace the origi-
nal tire as soon as possible to avoid
failure of the differential or AWD sys-
tem.
Tire size mismatch. Check all tire
sizes.
If your vehicle is equipped with differ-
ent tires (size, type, etc.) on the front
and rear, the message will appear. To
use the AWD system, equip the vehi-
cle with the same tires on the front
and rear.
