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.

When the ambient temperature is lower than 32 °F (0 °C) and the remaining high voltage battery is low, the power of the vehicle with a trailer can be dropped, causing a trouble in acceleration or drop of the speed when driving hills.

When driving with a trailer, be sure to charge the high voltage battery more than 50 % if the ambient temperature is lower than 32 °F (0 °C).

Driving Range

When towing a trailer, your EV range calculation shown in the instrument cluster will slowly reduce as the vehicle detects the added power needed to overcome with wind resistance and load of the trailer. After the trailer is removed, the calculated range will need to to adjust to your normal driving style. Keep this in mind when changing driving styles to and from towing, and planning when to charge.

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.

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 occasionally to be sure the trailer bulbs are still working. You must also check the lights every time you disconnect and then reconnect the wires.

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 HYUNDAI dealer for assistance.

Driving on hills

Reduce speed and set to a higher regenerative braking system (paddle shifter) before you start down a long or steep downgrade. Otherwise, you might have to use your brakes so much that they would get overheated and may not operate efficiently.

If your trailer weighs more than the maximum trailer weight without trailer brakes and you have an reducer, drive in D (Drive) when towing a trailer.

Operating your vehicle in D (Drive) when towing a trailer can minimize heat build-up and extend the life of your reducer.

To prevent motor overheating:

If you tow a trailer with the maximum gross vehicle weight and maximum trailer weight, it can cause the motor to overheat. When driving in such conditions, allow the motor to idle until it cools down. You may proceed once the motor 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:

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).
Shift the gear to P (Park).
Set the parking brake and shut off the vehicle.
Place wheel chocks under the trailer wheels on the down hill side of the wheels.
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.
Reapply the brakes and parking brakes.
Shift the gear to P (Park) when the vehicle is parked on a uphill grade and in R (Reverse) on a downhill.
Shut off the vehicle and release the vehicle brakes but leave the parking brake set.

To prevent serious or fatal injury:

Do not get out of the vehicle without the parking brake firmly set. If you have left the vehicle 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.

Driving the vehicle after it has been parked on a hill

With the gear in P (Park), apply your brakes and hold the brake pedal down while you:
- Start your vehicle.
- Shift into gear into D (Drive) or R (Reverse).
- Release the parking brake,
Slowly remove your foot from the brake pedal.
Drive slowly until the trailer is clear of the chocks.
Stop and have someone pick up and store the chocks.
