and protection devices) is suitable for a
heavy-duty service.
.Electrical outlets may wear out with
normal usage or may be damaged over
time, making them unsuitable for electric
vehicle charging.
.Check the electrical outlet/plug while
charging and discontinue use if the
electrical outlet/plug is hot, then have the
electrical outlet serviced by a qualified
electrician.
.When outdoors, plug into an electrical
outlet that is weatherproof while in use.
.Do not attempt to use the charge cord
with non-utility supplied electrical power
sources such as backup generating
equipment.
.If the charge cord overheats, remove from
direct sunlight.
.Disconnect the charge cord from the
vehicle before disconnecting the
attachment plug from the wall.
.When charging your vehicle, ensure all
components are connected properly, there
is no damage, and the outlet has power.
.Do not use the charge cord in severe
weather conditions.

Driving and Operating 295
The trailer structure, the tires, and the
brakes must be all be rated to carry the
intended cargo. Inadequate trailer
equipment can cause the combination to
operate in an unexpected or unsafe manner.
Before driving, inspect all trailer hitch parts
and attachments, safety chains, electrical
connectors, lamps, tires, and mirrors. See
Towing Equipment0301. If the trailer has
electric brakes, start the combination
moving and then manually apply the trailer
brake controller to check the trailer brakes
work. During the trip, occasionally check
that the cargo and trailer are secure and
that the lamps and any trailer brakes are
working.
Towing with a Stability Control System
When towing, the stability control system
might be heard. The system reacts to
vehicle movement caused by the trailer,
which mainly occurs during cornering. This is
normal when towing heavier trailers.
Following Distance
Stay at least twice as far behind the vehicle
ahead as you would when driving without a
trailer to help to avoid heavy braking and
sudden turns.
Passing
More passing distance is needed when
towing a trailer. The combination of the
vehicle and trailer will not accelerate as
quickly and is much longer than the vehicle
alone. It is necessary to go much farther
beyond the passed vehicle before returning
to the lane. Pass on level roadways. Avoid
passing on hills if possible.
Backing Up
Hold the bottom of the steering wheel with
one hand. To move the trailer to the left,
move that hand to the left. To move the
trailer to the right, move that hand to the
right. Always back up slowly and, if possible,
have someone guide you.
Making Turns
Caution
Turn more slowly and make wider arcs
when towing a trailer to prevent damage
to your vehicle. Making very sharp turns
could cause the trailer to contact the
vehicle. Make wider turns than normal when towing,
so the trailer does not go over soft
shoulders, over curbs, or strike road signs,
trees, or other objects. Always signal turns
well in advance. Do not steer or brake
suddenly.
Driving on Grades
Reduce speed before starting down a long or
steep downhill grade. Use regenerative
braking to help slow the vehicle or maintain
speed by keeping the vehicle in gear and
limiting the initial battery charge to 80% or
less. Avoid using Regen on Demand. See
Hill
and Mountain Roads 0190.
Viewing Systems
If equipped, the viewing systems on the
vehicle can improve visibility while hitching,
backing up, and driving with a trailer. See
Advanced Driver Assistance Systems 0244.
Parking on Hills
{Warning
To prevent serious injury or death,
always park your vehicle and trailer on a
level surface when possible.

Rear Gross Axle Weight Rating
(GAWR-RR)
The GAWR-RR is the total weight that can be
supported by the rear axle of the vehicle. Do
not exceed the GAWR-RR for the vehicle,
with the tow vehicle and trailer fully loaded
for the trip including the weight of the
trailer tongue. If using a weight-distributing
hitch, do not exceed the GAWR-RR before
applying the weight distribution spring bars.
The GAWR-RR for the vehicle is on the
Trailering Information Label.
For additional assistance with trailering or
additional information, see your dealer.
Towing Equipment
Hitches
{Warning
In order to avoid serious injury or
property damage, always follow the hitch
manufacturer's instructions when securing
your draw bar/coupling device to the
vehicle's hitch receiver.
Ensure that the draw bar/coupling device
is secured with a locking retainer pin or
other means such that rotation of the pin
or locking mechanism will not cause the
pin to back out or loosen during use.
Failure to correctly secure the draw bar/
coupling device to the receiver can result
in separation of the hitch/receiver while
towing.
Conventional Hitch
A conventional hitch is bolted to the frame
or cross member of the tow vehicle, and is
generally rated Class 2, 3, or 4.
Always use the correct hitch equipment for
your vehicle. Crosswinds, large trucks going
by, and rough roads can affect the trailer
and the hitch.Proper hitch equipment for your vehicle
helps maintain control of the vehicle-trailer
combination. Many trailers can be towed
using a weight-carrying hitch with a coupler
latched to the hitch ball, or a tow eye
latched to a pintle hook. Other trailers may
require a weight-distributing hitch that uses
spring bars to distribute the trailer tongue
weight between your vehicle and trailer
axles. See
“Maximum Trailer Tongue Weight
Rating” underTrailer Towing 0297 for
weight limits with various hitch types.
Never attach rental hitches or other
bumper-type hitches. Only use
frame-mounted hitches that do not attach to
the bumper.
Consider using mechanical sway controls
with any trailer. Ask a trailering professional
about sway controls or refer to the trailer
manufacturer's recommendations and
instructions.Weight-Distributing Hitch and
Adjustment
A weight-distributing hitch may be useful
with some trailers. Use the following
guidelines to determine if a
weight-distributing hitch should be used.
