■Hitches
Read the trailer manufacturer’s instructions, and select the appropriate draw bar for
the height of the trailer you will be towing.■Weight distribution hitches
Your vehicle is designed to tow without the need for a load distributing hitch. If you
wish to use one, please consult your trailer maker for proper installation and set-up.
Improper set-up could degrade the handling, stability, and braking performance of
your vehicle.■Safety chains
Always use safety chains when you tow a trailer. Leave enough slack to allow the
trailer to turn corners easily, but do not allow the chains to drag on the ground.■Sway control
This device can be used if your trailer tends to sway. Your trailer maker can tell you
what kind of sway control you need and how to install it. Improper installation could
degrade the handling and stability of your vehicle.■Automatic transmission cooler
Install an additional ATF (automatic transmission fluid) cooler to help prevent the
transmission from overheating, and damaging. You can get the additional ATF
cooler at a dealer.An additional ATF cooler is required to keep the transmission from overheating when
towing more than 3,500 lbs (1,588 kg). You can get the additional ATF cooler at a dealer.■Trailer mirrors
Many states, provinces and territories require special exterior mirrors when towing a
trailer. Install special mirrors whenever you cannot clearly see behind you, or if the
trailer creates a blind spot.4WD models

*
Important Safety Reminders
The LKAS is for your convenience only. It is not a
substitute for your vehicle control. The system does
not work if you take your hands off the steering
wheel or fail to steer the vehicle.
2 Multi-Information Display (MID) Warning
and Information Messages P. 96
Do not place an object on the top of the instrument
panel. It may reflect onto the windshield and prevent
the system from detecting lane lines properly.
The LKAS is convenient when it is used on freeways.
The LKAS may not work properly under the following
conditions:•Your tires are over or under inflated.•Your tires or wheels are of varied size or
construction.•Your vehicle’s suspension has been altered,
changing the height of the vehicle.•Your vehicle has heavy load in the trunk or on the
rear seats.•A compact spare tire
* is mounted.
•Driving on snowy or wet roads.•Roadway lane markers are difficult to see due to
weather (rain, snow, fog, etc.) or road conditions.•Driving on a road with temporary lane markings.•Multiple or varied lane markings are visible on the
pavement due to road repairs or old lane markings.•Roadway objects or structures are misinterpreted
as lane markers.•On non-freeway roadways and on freeways with
many curves.
■Steering input assist
The system applies torque to the
steering to keep the vehicle between
the left and right lane lines. The
applied torque becomes stronger as the
vehicle gets closer to either of the lane
lines.
■Audible and visual alerts
Beeps and a warning display alert
you that the vehicle is drifting out of
a detected lane.
When you operate the turn signals to change lanes, the system is suspended, and
resumes after the signals are off.
If you make a lane change without operating the turn signals, the LKAS alerts
activate, and torque is applied to the steering.
