Hill-Start Assist Control (HAC)
Hill-Start Assist Control 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 5
seconds and releases the brake after 5
seconds or when the accelerator pedal is
depressed.
WARNING
Always be ready to depress the
accelerator pedal when starting off
an incline. Hill-Start Assist Control
activates only for approximately 5
seconds.
Information
• Hill-Start Assist Control does not
operate when the gear is shifted to P
(Park) or N (Neutral).
• Hill-Start Assist Control activates even
when the ESC (Electronic Stability
Control) is off. However, it does not
activate, when ESC does not operate
normally.

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 we recommend that you call
an authorized retailer of Genesis Branded
products 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.

an 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
AWD vehicles must be towed with
a wheel lift and dollies or flatbed
equipment with all the wheels off the

This could damage the AWD system.
• Never engage the parking brake while
running the engine on a car lift. This
may damage the AWD system.
Dynamometer testing
An AWD vehicle must be tested on a
special four wheel chassis dynamometer.
OJX1069026LOJX1069026L[A] : Roll tester (Speedometer),
[B] : Temporary free roller
An AWD 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

Backing up
Hold the bottom of the steering wheel
with one hand. Then, to move the trailer
to the left, move your hand to the left. To
move the trailer to the right, move your
hand to the right. Always back up slowly
and, if possible, have someone guide
you.
Making turns
When you’re turning with a trailer, make
wider turns than normal. Do this so your
trailer won’t strike soft shoulders, curbs,
road signs, trees, or other objects. Avoid
jerky or sudden maneuvers. Signal well in
advance.
Turn signals
When you tow a trailer, your vehicle has
to have a different turn signal flasher and
extra wiring. The green arrows on your
instrument panel will flash whenever you
signal a turn or lane change. Properly
connected, the trailer lights will also flash
to alert other drivers you’re about to turn,
change lanes, or stop.
When towing a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer
are burned out. Thus, you may think
drivers behind you are seeing your
signals when, in fact, they are not. It’s
important to check frequently to be sure
the trailer bulbs are still working. You
must also check the lights every time
you disconnect and then reconnect the
wires.
WARNING
Do not connect a trailer lighting system
directly to your vehicle’s lighting
system. Use an approved trailer wiring
harness. Failure to do so could result in
damage to the vehicle electrical system
and/or personal injury. Consult an
authorized retailer of Genesis Branded
products for assistance.
Driving on hills
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift to a lower
gear, you may have to use your brakes
excessively and they would overheat and
may not operate efficiently.
On a long uphill grade, shift to a lower
gear and reduce your speed to around
45 mph (70 km/h) to reduce the possibility of engine and transmission
overheating.
If your trailer weighs more than the
maximum trailer weight without trailer
brakes and you have an automatic
transmission, you should drive in D
(Drive) when towing a trailer.
Operating your vehicle in D (Drive)
when towing a trailer will minimize heat
build-up and extend the life of your
transmission.
