Be sure the parking brake is firmly set when parked and
the gear shift lever is in the PARK position. When
parking on a hill you should apply the parking brake
before placing the gear shift lever in PARK, otherwise the
load on the transmission locking mechanism may make it
difficult to move the selector out of PARK.
WARNING!
•Always fully apply the parking brake when leav-
ing your vehicle, or it may roll and cause damage
or injury. Also be certain to leave an automatic
transmission in Park, a manual transmission in
Reverse or First gear. Failure to do so may allow
the vehicle to roll and cause damage or injury.
•Never leave children alone in a vehicle. Leaving
children in a vehicle unattended is dangerous for
a number of reasons. A child or others could be
seriously or fatally injured. Don’t leave the keys
in the ignition. A child could operate power
windows, other controls, or move the vehicle.
•Be sure the parking brake is fully disengaged before
driving, failure to do so can lead to brake problems
due to excessive heating of the rear brakes.

HSA on Automatic Vehicles
The system will work in reverse and all forward gears on
vehicles equipped with an automatic transmission. The
system will not activate if the vehicle is placed in neutral.
HSA on Manual Vehicles
The system will work in reverse, forward gears, and
neutral on manual transmission equipped vehicles. The
system does not recognize neutral on manual vehicles,
thus it will hold the vehicle on an incline for a short
period while in neutral, regardless of clutch position. To
prevent this, do not attempt to roll down a hill simply by
putting the transmission in neutral and letting gravity act
on the vehicle, as the HSA will prevent the vehicle from
rolling. Instead, use the appropriate gear for moving in
the desired direction.
Towing and Hauling with HSA (Vehicles Equipped
with Automatic Transmissions Only)
The HSA system does not know if your vehicle is loaded
or towing a trailer, unless the “TOW/HAUL” button,
located on the transmission gear selector lever, is se-
lected. When activated, the “TOW/HAUL” light will
illuminate in the instrument cluster. Refer to the “Starting
and Operating” Section of this manual for more informa-
tion on the “TOW/HAUL” mode. In order to accommo-
date the extra weight entailed under towing and hauling
conditions and to increase driver comfort while launch-
ing on a hill, the system recognizes when the Tow/Haul
button is activated and compensates by releasing brake
pressure at a slower rate while throttle is applied to in
order to prevent the vehicle from rolling down the hill.

WARNING!
If you use a trailer brake controller with your trailer,
your trailer brakes may be activated and deactivated
with the brake switch. If so, when the brake pedal is
released there may not be enough brake pressure to
hold the vehicle and trailer on a hill and this could
cause a collision with another vehicle or object
behind you. In order to avoid rolling down the
incline while resuming acceleration, manually acti-
vate the trailer brake or apply more vehicle brake
pressure prior to releasing the brake pedal. Always
remember the driver is responsible for braking the
vehicle.
WARNING!
HSA is not a parking brake. If you stop the vehicle
on a hill without putting the transmission in park or
using the parking brake, it will roll down the incline
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 parking brake
on manual transmission vehicle.
2. Start the engine.

WARNING!
Improper towing can lead to an injury accident.
Follow these guidelines to make your trailer towing
as safe as possible:
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
•When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
•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
P for Park. With a manual transmission, shift the
transmission into reverse. And with four-wheel-drive
vehicles, make sure the transfer case is not in neutral.
Always, block orchockthe 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

If using a manual transmission vehicle for trailer towing,
all starts must be in FIRST gear to avoid excessive clutch
slippage.
Towing Tips — Automatic Transmission
The “D” range can be selected when towing. However, if
frequent shifting occurs while in this range, the “TOW
HAUL” or “OD/OFF” range should be selected.
NOTE:Using the “TOW HAUL” or “OD/OFF” range
while operating the vehicle under heavy operating con-
ditions will improve performance and extend transmis-
sion life by reducing excessive shifting and heat build up.
This action will also provide better engine braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. See Schedule “B” in
section 8 of this manual for transmission fluid change
intervals.NOTE:Check the automatic transmission fluid level
before towing.
Towing Tips — Tow/Haul (If Equipped)
To reduce potential for automatic transmission overheat-
ing, turn the “TOW HAUL OD/OFF” feature ON when
driving in hilly areas or shift the transmission to Drive
position 2 on more severe grades.
Towing Tips — Electronic Speed Control (If
Equipped)
Don’t use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
