the trailer brakes are inadequate for the
load, the vehicle may not stop as
expected. You and others could be
seriously injured. The vehicle may also be

trailer only if all the steps in this section

Driving with a Trailer
Trailering is different than just driving the
vehicle by itself. Trailering affects handling,
acceleration, braking, and durability.
Successful and safe trailering requires proper
use of the correct equipment.
The following information has many
time-tested, important trailering tips and
safety rules. Many of these are important
for your safety and that of your passengers.
Read this section carefully before towing a
trailer.
When towing a trailer:
Become familiar with, and follow all state
and local laws that apply to trailer
towing. These requirements vary from
state to state.
State laws may require the use of
extended side view mirrors. If your
visibility is limited or restricted while
towing, install extended side view mirrors
on your vehicle, even if not required.
Do not tow a trailer during the first
800 km (500 mi) of vehicle use to prevent
damage to vehicle.
Do not drive over 800 km/h (50 mph) and
do not make starts at full throttle during
the first 800 km (500 mi) of trailer
towing.
Tow in D (Drive). Tow/Haul Mode is
recommended for heavier trailers. See
Driver Mode Control 0 195.
One-Pedal Driving can be a useful feature
when towing. See One-Pedal Driving
0 188.

Rear Cross Traffic Alert (RCTA)

Do not use Automatic Parking Assist (APA)
while towing a trailer.
Towing a trailer requires experience. The
combination of the vehicle and trailer is
longer and not as responsive as the vehicle
itself. Become familiar with handling and
braking of the combination by driving on a
level road surface before driving on public
roads.
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 Equipment 0 259. If the trailer has
