Safety chains
You should always attach chains between
your vehicle and your trailer.
Instructions about safety chains may
be provided by the hitch manufacturer
or trailer manufacturer. Follow the
manufacturer’s recommendation for
attaching safety chains. Always leave just
enough slack so you can turn with your
trailer. And, never allow safety chains to
drag on the ground.
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.

NOTICE
To prevent engine and/or transmission
overheating:
• When towing a trailer on steep
grades (in excess of 6%) pay close
attention to the engine coolant
temperature gauge to ensure the
engine does not overheat. If the
needle of the coolant temperature
gauge moves towards “H” (HOT),
pull over and stop as soon as it is
safe to do so, and allow the engine
to idle until it cools down. You may
proceed once the engine has cooled
sufficiently.
• If you tow a trailer with the maximum
gross vehicle weight and maximum
trailer weight, it can cause the
engine or transmission to overheat.
When driving in such conditions,
allow the engine to idle until it cools
down. You may proceed once the
engine or transmission has cooled
sufficiently.
• When towing a trailer, your vehicle
speed may be much slower than the
general flow of traffic, especially
when climbing an uphill grade. Use
the right hand lane when towing a
trailer on an uphill grade. Choose
your vehicle speed according to the
maximum posted speed limit for
vehicles with trailers, the steepness
of the grade, and your trailer weight.
Parking on hills
Generally, if you have a trailer attached
to your vehicle, you should not park your
vehicle on a hill.
However, if you ever have to park your
trailer on a hill, here’s how to do it:
1. Pull the vehicle into the parking space.
Turn the steering wheel in the
direction of the curb (right if headed
down hill, left if headed up hill).
2. Shift the gear to P (Park).
3. Set the parking brake and shut off the
vehicle.
4. Place wheel chocks under the trailer
wheels on the down hill side of the
wheels.
5. Start the vehicle, hold the brakes, shift
to neutral, release the parking brake
and slowly release the brakes until the
trailer chocks absorb the load.
6. Reapply the brakes and parking
brakes.
7. Shift the gear to P (Park) when the
vehicle is parked on a uphill grade and
in R (Reverse) on a downhill.
8. Shut off the vehicle and release the
vehicle brakes but leave the parking
brake set.
WARNING
To prevent serious or fatal injury:
• Do not get out of the vehicle without
the parking brake firmly set. If you
have left the engine running, the
vehicle can move suddenly. You and
others could be seriously or fatally
injured.
• Do not apply the accelerator pedal to
hold the vehicle on an uphill.

WARNING
Take the following precautions when
using Forward Collision-Avoidance
Assist:
• For your safety, change the Settings
after parking the vehicle at a safe
location.
• With ‘Active assist’ or ‘Warning only’
selected, when ESC is turned off by
pressing and holding the ESC OFF
button for more than 3 seconds,
Forward Collision-Avoidance Assist
will turn off automatically. In this
case, the system cannot be set
from the Settings menu and the

warning light will illuminate on the
cluster which is normal. If ESC is
turned on by pressing the ESC OFF
button, Forward Collision-Avoidance
Assist will maintain the last setting.
• Forward Collision-Avoidance Assist
does not operate in all situations or
cannot avoid all collisions.
• The driver should hold the
responsibility to control the vehicle.
Do not solely depend on Forward
Collision-Avoidance Assist. Rather,
maintain a safe braking distance, and
if necessary, depress the brake pedal
to reduce driving speed or to stop
the vehicle.
• Never deliberately operate Forward
Collision-Avoidance Assist on people,
animal, objects, etc. It may cause
serious injury or death.
• Forward Collision-Avoidance
Assist may not operate if the driver
depresses the brake pedal to avoid
collision. •
Depending on the road and driving
conditions, Forward Collision-
Avoidance Assist may warn the driver
late or may not warn the driver.
• During Forward Collision-Avoidance
Assist operation, the vehicle may
stop suddenly injuring passengers
and shifting loose objects. Always
have the seat belt on and keep loose
objects secured.
• If any other system’s warning
message is displayed or audible
warning is generated, Forward
Collision-Avoidance Assist warning
message may not be displayed
and audible warning may not be
generated.
• You may not hear the warning sound
of Forward Collision-Avoidance
Assist if the surrounding is noisy.
• Forward Collision-Avoidance
Assist may turn off or may not
operate properly or may operate
unnecessarily depending on the road
conditions and the surroundings.
WARNING
• Even if there is a problem with
Forward Collision-Avoidance
Assist, the vehicle’s basic braking
performance will operate normally.
• During emergency braking,
braking control by the system will
automatically cancel when the
driver excessively depresses the
accelerator pedal or sharply steers
the vehicle.

Lane Keeping Assist
• To warn the driver that the vehicle
is departing from the projected lane
in front, the green
indicator
light will blink on the cluster, and the
steering wheel will make adjustments
to keep the vehicle inside the lane.
• The system will operate when
your vehicle speed is between
approximately 40~120 mph (60~200
km/h).
OTMH070016N
Hands-off warning
If the driver takes their hands off the
steering wheel for several seconds,
the ‘Keep hands on the steering wheel’ warning message will appear on the
cluster, and an audible warning will
sound in stages.
WARNING
• The steering wheel may not be
assisted if the steering wheel is held
very tight or the steering wheel is
steered over a certain degree.
• Lane Keeping Assist does not operate
at all times. It is the responsibility of
the driver to safely steer the vehicle
and to maintain the vehicle in its
lane.
• The hands–off warning message
may appear late depending on road
conditions. Always have your hands
on the steering wheel while driving.
• If the steering wheel is held very
lightly, the hands–off warning
message may appear because the
system may not recognize that the
driver has their hands on the steering
wheel.
• If you attach objects to the steering
wheel, the hands-off warning may
not work properly.
