Trailer Towing
General Towing
Information
Only use towing equipment
that has been designed for the
vehicle. Contact your dealer or
trailering dealer for assistance
with preparing the vehicle to
tow a trailer. Read the entire
section before towing a trailer.
To tow a disabled vehicle, see
Transporting a Disabled
Vehicle (Electronic Shifter)
0450 or
Transporting a Disabled
Vehicle (Mechanical Shifter)
0 452. To tow the vehicle
behind another vehicle such as
a motor home, see
Recreational Vehicle Towing
0 454.
When towing with the 2.0L L4
engine, only use unleaded
gasoline with an octane rating
of 89 or higher. Using gasoline
with a lower octane rating while towing may damage the
engine and may not be
covered by the vehicle
warranty. See Recommended
Fuel (LSY 2.0L L4 Turbo
Engine)
0354 or
Recommended Fuel (L3B 2.7L
L4 Turbo and LF4 3.6L V6
Twin Turbo Engines) 0355.

360 Driving and Operating
If equipped, the following
driver assistance features
should be turned to alert or
off when towing a trailer:
.Automatic Emergency
Braking (AEB)
.Intelligent Brake Assist (IBA)
.Front Pedestrian
Braking (FPB)
If equipped with Lane Change
Alert (LCA), the LCA detection
zones that extend back from
the side of the vehicle do not
move further back when a
trailer is towed. Use caution
while changing lanes when
towing a trailer.
If equipped with Rear Cross
Traffic Alert (RCTA), use
caution while backing up when
towing a trailer, as the RCTA
detection zones that extend
out from the back of the
vehicle do not move further
back when a trailer is towed.
{Warning
To prevent serious injury or
death from carbon monoxide
(CO), when towing a trailer:
.Do not drive with the
liftgate, trunk/hatch,
or rear-most
window open.
.Fully open the air outlets
on or under the
instrument panel.
.Adjust the climate control
system to a setting that
brings in only outside air.
See “Climate Control
Systems” in the Index.
For more information about
carbon monoxide, see
Engine Exhaust 0271.
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 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
0365. 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.
