260 Driving and Operating
connectors, lamps, tires, and mirrors. See
Towing Equipment 0 265. 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 0 180.
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 0 219.
Parking on Hills
Warning
To prevent serious injury or death,
always park your vehicle and trailer on a
level surface when possible.
When parking your vehicle and trailer on
a hill:
1. Press and hold the brake pedal, but do
not shift into P (Park). Turn the wheels
toward the curb if facing downhill or
toward traffic if facing uphill.
