All Wheel Drive (AWD) 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.
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.
WARNING
If the AWD () warning light stays on
the instrument cluster, your vehicle
may have a malfunction with the
AWD system. Whenever the AWD
(
) warning light illuminates, have
the vehicle inspected by an authorized
retailer of Genesis Branded products as
soon as possible.
NOTICE

[Do not drive in water if the water
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 condition is returned.

[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 AWD
vehicle is towed by a flat bed tow
truck.

Driving up or down hills

[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.
WARNING
Do not drive across the contour of steep
hills. A slight change in the wheel angle
can destabilize the vehicle, or a stable
vehicle may lose stability if the vehicle
stops its forward motion. Your vehicle
may roll over and lead to a serious injury
or death.
Emergency Precautions
Tires
When replacing tires, be sure to equip
all four tires with the same size, type,
tread pattern, brand and load-carrying
capacity.
WARNING
Do not use tire and wheel with 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.
In an emergency situation, a compact
spare tire may be used. But, do not use
the compact spare tire continuously.
Repair or replace the original tire as
soon as possible to avoid failure of the
differential or AWD system.

Driving Your Vehicle
Driving in the Rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or on
slick pavement:

[Slow down and allow extra following
distance. A heavy rainfall makes
it harder to see and increases the
distance needed to stop your vehicle.

[Turn OFF your Smart Cruise Control

[Replace your windshield wiper blades
when they show signs of streaking or
missing areas on the windshield.

[Be sure your tires have enough tread.
If your tires do not have enough depth
of tire tread, making a quick stop on
wet pavement can cause a skid and
possibly lead to an accident. See “Tire
Tread” section in chapter 9.

[Turn on your headlights to make it
easier for others to see you.

[Driving too fast through large puddles
can affect your brakes. If you must go
through puddles, try to drive through
them slowly.

[If you believe your brakes may be wet,
apply them lightly while driving until
normal braking operation returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the water.
The best advice is SLOW DOWN when
the road is wet.
The risk of hydroplaning increases as the
depth of tire tread decreases, refer to
“Tire Tread” section in chapter 9.
Driving in Flooded Areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel hub.
Drive through any water slowly. Allow
adequate stopping distance because
brake performance may be reduced.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.
Highway Driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or damage
the tires.
Do not install worn-out or damaged tires,
which may reduce traction or fail the
braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as specified
on your tires.
Fuel, engine coolant and engine oil
Driving at higher speeds on the highway
consumes more fuel and is less efficient
than driving at a slower, more moderate
speed. Maintain a moderate speed in
order to conserve fuel when driving on
the highway.
Be sure to check both the engine coolant
level and the engine oil before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.

6-74
Driving Your Vehicle
Do not let ice and snow accumulate
underneath
Under some conditions, snow and ice
can build up under the fenders and
interfere with the steering. When driving
in such conditions during the severe
winter, you should check underneath
the vehicle on a regular basis, to ensure
that the front wheels and the steering
components is unblocked.
Carry emergency equipment
In accordance with weather conditions,
you should carry appropriate emergency
equipment, while driving. Some of the
items you may want to carry include tire
chains, tow straps or chains, flashlight,
emergency flares, sand, shovel, jumper
cables, window scraper, gloves, ground
cloth, coveralls, blanket, etc.
Do not place objects or materials in the
engine compartment
Putting objects or materials in the engine
compartment may cause an engine
failure or combustion, because they may
block the engine cooling. Such damage
will not be covered by the manufacturer’s
warranty.
Drive your vehicle when water vapor
condenses and accumulates inside the
exhaust pipes
When the vehicle is stopped for a
long time in winter while the engine is
running, water vapor may condense and
accumulate inside the exhaust pipes.
Water in the exhaust pipes may cause
noise, etc., but it is drained driving at
medium to high speed.

If You Have a Flat Tire While
Driving
If a tire goes flat while you are driving:
• Take your foot off the accelerator
pedal and let the vehicle slow down
while driving straight ahead. Do not
apply the brakes immediately or
attempt to pull off the road as this
may cause loss of vehicle control
resulting in an accident. When the
vehicle has slowed to such a speed
that it is safe to do so, brake carefully
and pull off the road. Drive off the
road as far as possible and park on
firm, level ground. If you are on a
divided highway, do not park in the
median area between the two traffic
lanes.
• When the vehicle is stopped, press the
hazard warning flasher button, shift
the gear to P (Park), apply the parking
brake, and press the Engine Start/Stop
button to the OFF position.
• Have all passengers get out of the
vehicle. Be sure they all get out on the
side of the vehicle that is away from
traffic.
• When changing a flat tire, follow the
instructions provided later in this
chapter.
IF THE ENGINE WILL NOT
START
• Be sure to shift the gear to N (Neutral)
or P (Park). The engine starts only
when the gear is in N (Neutral) or P
(Park).
• Turn on the interior light. If the light
dims or goes out when you operate
the starter, the battery is drained.
See instructions for “Jump Starting”
provided in this chapter.
• Check the fuel level and add fuel if
necessary.
If the vehicle still does not start, call an
authorized retailer of Genesis Branded
products for assistance.
NOTICE
Push or pull starting the vehicle may
cause the catalytic converter to
overload which can lead to damage to
the emission control system.
