system will release brake pressure in proportion to
amount of throttle applied as the vehicle starts to move in
the intended direction of travel.
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
•Vehicle must be stopped.
•Vehicle must be on a 3% (approximate) for manual
transmission and 6% (approximate) for automatic
transmissions.
•Gear selection matches vehicle uphill direction (i.e.,
vehicle facing uphill is in forward gear; vehicle back-
ing uphill is in REVERSE gear).
WARNING!
There may be situations on minor hills with a loaded
vehicle, or while pulling a trailer, when the system
will not activate and slight rolling may occur. This
could cause a collision with another vehicle or object.
Always remember the driver is responsible for brak-
ing the vehicle.
HSA Off
If you wish to turn off the HSA system, it can be done in
the Uconnect® settings. Refer to#Uconnect® Settings#in
#Understanding Your Instrument Panel#for further infor-
mation.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. The ESC
corrects for oversteering and understeering the vehicle

FUEL REQUIREMENTS
3.6L Engine — If Equipped
This engine is designed to meet all emis-
sions regulations and provide excellent
fuel economy and performance when us-
ing high-quality unleaded “regular” gaso-
line having an octane rating of 87. The use
of premium gasoline is not recommended, as it will not
provide any benefit over regular gasoline in these
engines.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required. Poor quality gasoline can cause problems such
as hard starting, stalling, and hesitations. If you experi-
ence these symptoms, try another brand of gasoline
before considering service for the vehicle.
Over 40 auto manufacturers worldwide have issued and
endorsed consistent gasoline specifications (the World-
wide Fuel Charter, WWFC) which define fuel properties
necessary to deliver enhanced emissions, performance,
and durability for your vehicle. The manufacturer recom-
mends the use of gasolines that meet the WWFC speci-
fications if they are available.
5.7L Engine (With Automatic Transmission)
The 5.7L engine (with automatic transmis-
sion) is designed to meet all emissions
regulations and provide satisfactory fuel
economy and performance when using
high-quality unleaded gasoline having an
octane range of 87 to 89. The manufacturer recommends
the use of 89 octane for optimum performance. The use of

Trailer Towing Weights (Maximum Trailer Weight Ratings)
The following chart provides the maximum trailer
weight ratings towable for your given drivetrain.
Engine/TransmissionFrontal AreaMax. GTW (Gross
Trailer Wt.)Max. Tongue Wt.
3.6L Automatic12 sq ft (1.11 sq m) 1,000 lbs (454 kg)100 lbs (45 kg)
5.7L Automatic12 sq ft (1.11 sq m) 1,000 lbs (454 kg)100 lbs (45 kg)
Refer to local laws for maximum trailer towing speeds.
Trailer And Tongue Weight
Always load a trailer with 60% to 65% of the weight in
the front of the trailer. This places 10% to 15% of the
Gross Trailer Weight (GTW) on the tow hitch of your
vehicle. Loads balanced over the wheels or heavier in the
rear can cause the trailer to swayseverelyside to side
which will cause loss of control of the vehicle and trailer.
Failure to load trailers heavier in front is the cause of
many trailer collisions.
Never exceed the maximum tongue weight stamped on
your bumper or trailer hitch.
440 STARTING AND OPERATING

CAUTION!(Continued)
•Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps
the engine and other parts of the vehicle wear in at
the heavier loads.
WARNING!
Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as
possible:
•Make certain that the load is secured in the trailer
and it 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 a collision.
(Continued)
WARNING!(Continued)
•When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance, or dam-
age to brakes, axle, engine, transmission, steering,
suspension, chassis 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 PARK. Always, block or$chock$
the trailer wheels.
•GCWR must not be exceeded.

Towing Tips
Before setting out on a trip, practice turning, stopping,
and backing up the trailer in an area located away from
heavy traffic.
Automatic Transmission — If Equipped
The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to avoid
frequent shifting when towing. However, if frequent
shifting does occur while in DRIVE, you can use the
AutoStick® shift control to manually select a lower gear.
NOTE:Using a lower gear while operating the vehicle
under heavy loading conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up. This action will also
provide better engine braking.

452 WHAT TO DO IN EMERGENCIES

WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided. Have the deflated (flat) tire
repaired or replaced immediately.
Preparations For Jacking
1. Park the vehicle on a firm, level surface as far from the
edge of the roadway as possible. Avoid icy or slippery
areas.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic, pull far enough off
the road to avoid being hit when operating the jack
or changing the wheel.
2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Place the shift lever into PARK (automatic transmis-
sion) or 1st gear (manual transmission).
5. Turn OFF the ignition.
6. Block both the front and rear of the wheel diagonally
opposite of the jacking position. For
example, if changing the right front
tire, block the left rear wheel.
NOTE:Passengers should not remain
in the vehicle when the vehicle is
being jacked.

Jacking And Changing A Tire
WARNING!
Carefully follow these tire changing warnings to
help prevent personal injury or damage to your
vehicle:
•Always park on a firm, level surface as far from the
edge of the roadway as possible before raising the
vehicle.
•Turn on the Hazard Warning flasher.
•Block the wheel diagonally opposite the wheel to
be raised.
•Set the parking brake firmly and set an automatic
transmission in PARK; a manual transmission in
REVERSE.
•Never start or run the engine with the vehicle on a
jack.
(Continued)
WARNING!(Continued)
•Do not let anyone sit in the vehicle when it is on a
jack.
•Do not get under the vehicle when it is on a jack. If
you need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
•Only use the jack in the positions indicated and for
lifting this vehicle during a tire change.
•If working on or near a roadway, be extremely
careful of motor traffic.

470 WHAT TO DO IN EMERGENCIES

WARNING!
•Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is ON. You can be injured by
moving fan blades.
•Remove any metal jewelry such as rings, watch
bands and bracelets that could make an inadvertent
electrical contact. You could be seriously injured.
•Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
1. Set the parking brake, shift into PARK (automatic
transmission) or 1st gear (manual transmission) and
place the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electri-
cal accessories.
3. If using another vehicle to jump-start the battery, park
the vehicle within the jumper cables reach, set the
parking brake and make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this jump-starting procedure could
result in personal injury or property damage due to
battery explosion.
