WARNING! (Continued)
•HSA is not a parking brake. If you stop the vehicle
on a hill without putting the transmission in
PARK and using the parking brake, it will roll
down the hill and could cause a collision with
another vehicle or object. Always remember to use
the parking brake while parking on a hill, and that
the driver is responsible for braking the vehicle.
HSA Off
If you wish to turn off the HSA system, follow this
procedure:
1. Start with the engine off and vehicle in PARK (auto-
matic transmission) or NEUTRAL with clutch out
(manual transmission) with wheels straight. Apply park-
ing brake on manual transmission vehicle.
2. Start the engine.3. With the engine running, the brake applied, and the
clutch out, rotate the steering wheel 180° counterclock-
wise from center.
4. Press the ESP OFF switch four times within twenty
seconds.
5. Rotate the steering wheel 360° clockwise (180° clock-
wise from center).
6. Cycle ignition switch OFF then ON.
7. If the sequence was completed properly, the “ESP/
TCS Indicator Light” will blink several times to confirm
HSA is off.
Steps 1-7 must be completed within 90 seconds to turn off
HSA. Repeat steps 1-7 to re-enable HSA functionality.

WARNING! (Continued)
•Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on
the tow vehicle. Put the tow vehicle automatic
transmission in PARK. With a manual transmis-
sion, shift the transmission into first gear. And
with four-wheel-drive vehicles, make sure the
transfer case is not in N (Neutral). Always, block
or\bchock\b the trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
(Continued)
WARNING! (Continued)
4. Tongue weight rating for the trailer hitch utilized
(This requirement may limit the ability to always
achieve the 10% to 15% range of tongue weight as a
percentage of total trailer weight).
Towing Requirements – Tires

Do not attempt to tow a trailer while using a compact
spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting and Oper-
ating” for proper tire inflation procedures.
Check the trailer tires for proper tire inflation pres-
sures before trailer usage.
430 STARTING AND OPERATING

RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
CAUTION!
Front or rear wheel lifts should not be used. Internal
damage to the transmission or transfer case will occur
if a front or rear wheel lift is used when recreational
towing.
Two-Wheel Drive Models
Recreational towing is allowed ONLY if the rear drive-
shaft is removed. See your authorized dealer or refer to
the Service Manual.Towing with the rear wheels on the
ground while the driveshaft is connected can result in
severe transmission damage.
WARNING!
If the driveshaft is removed, the vehicle can roll even
if the transmission is in PARK, which could cause
serious injury or death.
The parking brake must be firmly engaged and the
wheels chocked during driveshaft removal and installa-
tion. The parking brake must remain engaged unless the
vehicle is securely and properly connected to the tow
vehicle, or the driveshaft is completely reinstalled. See
your authorized dealer for proper driveshaft removal
and reinstallation procedures, including flange
orientation/alignment, use of thread-locking compound,
proper bolt torque specifications, etc.

STARTING AND OPERATING 435

Four-Wheel Drive Models
NOTE:The transfer case must be shifted into N (Neu-
tral), automatic transmission must be shifted into PARK,
and manual transmission must be placed in gear (not in
NEUTRAL) for recreational towing.
Shifting Into Neutral (N)
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move,
even if the transmission is in PARK. The parking
brake should always be applied when the driver is
not in the vehicle. Use the following procedure to prepare your vehicle for
recreational towing.
CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in N (Neutral) before recre-
ational towing to prevent damage to internal parts.
1. Turn the engine off.
2. Press the brake pedal.
3. Shift the automatic transmission into NEUTRAL or
press the clutch pedal on a manual transmission.
4. Shift the transfer case lever into N (Neutral).
5. Start the engine.
6. Shift the automatic transmission into DRIVE or the
manual transmission into gear.

moving fan blades.
•Remove any metal jewelry such as watch bands or
bracelets that might make an inadvertent electrical
