If a weight!distributing hitch is being used, it isrecommended to allow the shocks to inflate, therebyleveling the vehicle prior to adjusting the hitch.
Autoride®
With this feature, improved vehicle ride and handling isprovided under a variety of passenger and loadingconditions.
The system is fully automatic and uses a computercontroller to continuously monitor vehicle speed, wheelto body position, lift/dive and steering position of thevehicle. The controller then sends signals to each shockabsorber to independently adjust the damping level toprovide the optimum vehicle ride.
Autoride also interacts with the tow/haul mode that,when activated, will provide additional control of theshock absorbers. This additional control results in betterride and handling characteristics when the vehicle isloaded or towing a trailer. See“Tow/Haul Mode”underTowing a Traileron page 6!42for more information.
Towing a Trailer
If the vehicle has a two–mode hybrid engine, see theTwo–mode Hybrid manual for more information.
Do not tow a trailer during break!in. SeeNew VehicleBreak-Inon page 3!26for more information.
{WARNING:
The driver can lose control when pulling a trailer if
the correct equipment is not used or the vehicle is
not driven properly. For example, if the trailer is
too heavy, the brakes may not work well—or
even at all. The driver and passengers could be
seriously injured. The vehicle may also be
damaged; the resulting repairs would not be
covered by the vehicle warranty. Pull a trailer only
if all the steps in this section have been followed.
Ask your dealer/retailer for advice and information
about towing a trailer with the vehicle.
Notice:Pulling a trailer improperly can damage thevehicle and result in costly repairs not covered bythe vehicle warranty. To pull a trailer correctly,follow the advice in this section and see yourdealer/retailer for important information abouttowing a trailer with the vehicle.
To identify the trailering capacity of the vehicle, read theinformation in“Weight of the Trailer”that appears laterin this section.

During the trip, check occasionally to be sure that theload is secure and the lamps and any trailer brakesstill work.
Following Distance
Stay at least twice as far behind the vehicle ahead asyou would when driving the vehicle without a trailer.This can help to avoid heavy braking and sudden turns.
Passing
More passing distance is needed when towing a trailer.The combination will not accelerate as quickly and islonger so it is necessary to go much farther beyond thepassed vehicle before returning to the lane.
Backing Up
Hold the bottom of the steering wheel with one hand.Then, to move the trailer to the left, move that hand tothe left. To move the trailer to the right, move your handto the right. Always back up slowly and, if possible,have someone guide you.
Making Turns
Notice:Making very sharp turns while traileringcould cause the trailer to come in contact with thevehicle. The vehicle could be damaged. Avoidmaking very sharp turns while trailering.
When turning with a trailer, make wider turns thannormal. Do this so the trailer will not strike softshoulders, curbs, road signs, trees or other objects.Avoid jerky or sudden maneuvers. Signal wellin advance.
If the trailer turn signal bulbs burn out, the arrowson the instrument panel will still flash for turns. It isimportant to check occasionally to be sure the trailerbulbs are still working.

WARNING: (Continued)
vehicle and tire size combination and road
conditions. Follow that manufacturer's
instructions. To help avoid damage to the vehicle,
drive slowly, re!adjust or remove the device if it is
contacting the vehicle, and do not spin the
wheels. If you do find traction devices that will fit,
install them on the rear tires.
If a Tire Goes Flat
It is unusual for a tire to blowout while you are driving,especially if you maintain your vehicle's tires properly.If air goes out of a tire, it is much more likely to leak outslowly. But if you should ever have a blowout, here area few tips about what to expect and what to do:
If a front tire fails, the flat tire creates a drag that pullsthe vehicle toward that side. Take your foot off theaccelerator pedal and grip the steering wheel firmly.Steer to maintain lane position, and then gently braketo a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like askid and may require the same correction you woulduse in a skid. In any rear blowout remove your foot fromthe accelerator pedal. Get the vehicle under control bysteering the way you want the vehicle to go. It may bevery bumpy and noisy, but you can still steer. Gentlybrake to a stop, well off the road if possible.
{WARNING:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without the
appropriate safety equipment and training. If a
jack is provided with the vehicle, it is designed
only for changing a flat tire. If it is used for
anything else, you or others could be badly
injured or killed if the vehicle slips off the jack.
If a jack is provided with the vehicle, only use
it for changing a flat tire.
If a tire goes flat, the next part shows how to use thejacking equipment to change a flat tire safely.
