Driving at Night
Night driving presents more hazards than
driving in the daylight. Here are some
important tips to remember:
• Slow down and keep more distance
between you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.
• Adjust your mirrors to reduce the glare
from other drivers’ headlamps.
• Keep your headlamps clean and
properly aimed. Dirty or improperly
aimed headlamps will make it much
more difficult to see at night.
• Avoid staring directly at the
headlamps of oncoming vehicles. You
could be temporarily blinded, and it
will take several seconds for your eyes
to readjust to the darkness.
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 Cruise Control. (if
equipped)
• 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 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 headlamps 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.

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
WARNING
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 affected.
We recommend that you use snow tires when road temperature is below 45°F (7°C).
Refer to the below chart, and mount the recommended snow tire for your vehicle.

If you mount snow tires on your vehicle, make sure to use the same Inflation pressure
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.

Check spark plugs and ignition system
Inspect the spark plugs, as specified in
chapter 8. If necessary, replace them.
Also check all ignition wirings and
components for any cracks, wear-out,
and damage.
To prevent locks from freezing
To prevent the locks from being frozen,
spray approved de-icing fluid or glycerin
into key holes. When a lock opening is
already covered with ice, spray approved
de-icing fluid over the ice to remove it.
When an internal part of a lock freezes,
try to thaw it with a heated key. Carefully
use the heated key to avoid an injury.
Use approved window washer anti-
freeze solution in system
To prevent the window washer from
being frozen, add authorized window
washer anti-freeze solution, as specified
on the window washer container.
Window washer anti-freeze solution is
available from an authorized retailer of
Genesis Branded products, and most
vehicle accessory outlets. Do not use
engine coolant or other types of anti-
freeze solution, to prevent any damage
to the vehicle paint.Do not let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when there
is an accumulation of snow or ice around
or near the rear brakes or if the brakes
are wet. When there is the risk that your
parking brake may freeze, temporarily
apply it with the gear in P (Park). Also,
block the rear wheels in advance, so the
vehicle may not roll. Then, release the
parking brake.
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.

Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to
your country’s regulations and that
it is properly installed and operating
correctly.
If your trailer weighs more than the
maximum trailer weight without trailer
brakes loaded, then it needs its own
brakes and they must be adequate. Be
sure to read and follow the instructions
for the trailer brakes so you’ll be able
to install, adjust and maintain them
properly. Be sure not to modify your
vehicle’s brake system.
WARNING
Do not use a trailer with its own brakes
unless you are absolutely certain that
you have properly set up the brake
system. This is not a task for amateurs.
Use an experienced, competent trailer
shop for this work.
Driving with a Trailer
Towing a trailer requires a certain
amount of experience. Before setting
out for the open road, you must get to
know your trailer. Acquaint yourself with
the feel of handling and braking with the
added weight of the trailer. And always
keep in mind that the vehicle you are
driving is now longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch
and platform, safety chains, electrical
connector(s), lights, tires and brakes.
During your trip, occasionally check
to be sure that the load is secure, and
that the lights and trailer brakes are still
working.
Distance
Stay at least twice as far behind the
vehicle ahead as you would when driving
your vehicle without a trailer. This can
help you avoid situations that require
heavy braking and sudden turns.
Passing
You will need more passing distance up
ahead when you’re towing a trailer. And,
because of the increased vehicle length,
you’ll need to go much farther beyond
the passed vehicle before you can return
to your lane.

Driving Your Vehicle
6-68
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.
