The system is activated when the ignition key
is turned to RUN and will automatically adjust
vehicle height thereafter. The system may exhaust
(lower vehicle height) for up to 10 minutes after
the ignition key has been turned to LOCK. You
may hear the air compressor operating when the
height is being adjusted.
If a weight-distributing hitch is being used, it is
recommended to allow the shocks to inflate,
thereby leveling the vehicle prior to adjusting the
height. See“Weight distributing Hitches and
Weight Carrying Hitches”underTowing a Trailer
on page 6!42.
Towing
Towing Your Vehicle
To avoid damage, the disabled vehicle should betowed with all four wheels off the ground. Consult yourdealer/retailer or a professional towing service if thedisabled vehicle must be towed. SeeRoadside Serviceo n p a g e 9!8.
To tow the vehicle behind another vehicle forrecreational purposes (such as behind a motorhome),see“Recreational Vehicle Towing”following.
Recreational Vehicle Towing
If the vehicle has a two–mode hybrid engine, see theTwo–mode Hybrid manual for more information.
Recreational vehicle towing means towing the vehiclebehind another vehicle–such as behind a motorhome.The two most common types of recreational vehicletowing are known as“dinghy towing”(towing the vehiclewith all four wheels on the ground) and“dolly towing”(towing the vehicle with two wheels on the ground andtwo wheels up on a device known as a“dolly”).
Here are some important things to consider beforerecreational vehicle towing:
.What is the towing capacity of the towing vehicle?Be sure to read the tow vehicle manufacturer'srecommendations.
.What is the distance that will be travelled? Somevehicles have restrictions on how far and how longthey can tow.
.Is the proper towing equipment going to be used?See your dealer/retailer or trailering professionalfor additional advice and equipmentrecommendations.
.Is the vehicle ready to be towed? Just as preparingthe vehicle for a long trip, make sure the vehicle isprepared to be towed. SeeBefore Leaving on aLong Trip on page 6!26.

Two-wheel-drive vehicles should not be towed withthe rear wheels on the ground. Two-wheel-drivetransmissions have no provisions for internal lubricationwhile being towed.
Dolly Towing (Rear Wheels Off the Ground)
Use the following procedure to dinghy tow atwo-wheel-drive vehicle from the rear:
1. Attach the dolly to the tow vehicle following thedolly manufacturer's instructions.
2. Drive the rear wheels onto the dolly.
3. Firmly set the parking brake. SeeParking Brakeon page 3!38.
4. Put the transmission in P (Park).
5. Secure the vehicle to the dolly following themanufacturer's instructions.
6. Use an adequate clamping device designed fortowing to ensure that the front wheels are lockedinto the straight position.
7. Turn the ignition to LOCK/OFF.
Level Control
Automatic Level Control
The automatic level control rear suspension is availableon light!duty vehicles and comes as a part of theAutoride®suspension, if equipped.
This type of level control is fully automatic and willprovide a better leveled riding position as well as betterhandling under a variety of passenger and loadingconditions. An air compressor connected to the rearshocks will raise or lower the rear of the vehicle tomaintain proper vehicle height. The system is activatedwhen the ignition key is turned to ON/RUN and willautomatically adjust vehicle height thereafter. Thesystem may exhaust (lower vehicle height) for up toten minutes after the ignition key has been turned off.You may hear the air compressor operating when theheight is being adjusted.

Power Steering Fluid
SeeEngine CompartmentOverviewon page 7!16for reservoir location.
When to Check Power Steering Fluid
It is not necessary to regularly check power steeringfluid unless you suspect there is a leak in the system oryou hear an unusual noise. A fluid loss in this systemcould indicate a problem. Have the system inspectedand repaired.
How to Check Power Steering Fluid
To check the power steering fluid:
1. Turn the key off and let the engine compartmentcool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with aclean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the fluid levelon the dipstick.
The level should be at the FULL COLD mark.If necessary, add only enough fluid to bring the level upto the mark.
What to Use
To determine what kind of fluid to use, seeRecommended Fluids and Lubricantson page 8!10.Always use the proper fluid.
Notice:Use of the incorrect fluid may damage thevehicle and the damages may not be covered by thevehicle's warranty. Always use the correct fluidlisted inRecommended Fluids and Lubricantsonpage 8!10.

TPMS Sensor Matching Process
Each TPMS sensor has a unique identification code.Any time you rotate your vehicle's tires or replace oneor more of the TPMS sensors, the identification codeswill need to be matched to the new tire/wheel position.The sensors are matched to the tire/wheel positionsin the following order: driver side front tire, passengerside front tire, passenger side rear tire, and driverside rear tire using a TPMS diagnostic tool. See yourdealer/retailer for service.
The TPMS sensors can also be matched to each tire/wheel position by increasing or decreasing the tire's airpressure. If increasing the tire's air pressure, do notexceed the maximum inflation pressure indicated on thetire's sidewall.
To decrease air-pressure out of a tire you can use thepointed end of the valve cap, a pencil-style air pressuregage, or a key.
You have two minutes to match the first tire/wheelposition, and five minutes overall to match all four tire/wheel positions. If it takes longer than two minutes, tomatch the first tire and wheel, or more than five minutesto match all four tire and wheel positions the matchingprocess stops and you need to start over.
The TPMS sensor matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with theengine off.
3. PressQandKon the Remote Keyless Entry
(RKE) transmitter at the same time forapproximately five seconds. The horn sounds twiceto signal the receiver is in relearn mode and TIRELEARNING ACTIVE message displays on the DICscreen.
4. Start with the driver side front tire.
