vehicles, people, and objects, and most im-
portantly brake operation to ensure safe
operation of the vehicle under all road con-
ditions. Your complete attention is always
required while driving to maintain safe con-
trol of your vehicle. Failure to follow these
warnings can result in a collision or serious
personal injury.
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
WARNING!
•If you use a trailer brake controller with
your trailer, the trailer brakes may be acti-
vated and deactivated with the brake
switch. If so, there may not be enough
brake pressure to hold both the vehicle
and the trailer on a hill when the brake

pedal is released. In order to avoid rolling
down an incline while resuming accelera-
tion, manually activate the trailer brake or
apply more vehicle brake pressure prior to
releasing the brake pedal.
•HSA is not a parking brake. Always apply
the parking brake fully when leaving your
vehicle. Also, be certain to leave the trans-
mission in PARK.
•Failure to follow these warnings may
cause the vehicle to roll down the incline
and could collide with another vehicle,
object or person, and cause serious or
fatal injury. Always remember to use the
parking brake while parking on a hill and
that the driver is responsible for braking
the vehicle.
Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting, proceed as follows:•For vehicles equipped with the Electronic
Vehicle Information Center (EVIC), refer to
“Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument
Panel” for further information.
•If disabling HSA using Uconnect Settings,
refer to “Uconnect Settings” in “Understand-
ing Your Instrument Panel” for further
information.
For vehicles not equipped with the EVIC, per-
form the following steps:
1. Center the steering wheel (front wheels
pointing straight forward).
2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than
one-half turn to the left.
6. Push the “ESC Off” button located in the
lower switch bank below the climate control

Run Flat Tires — If EquippedRun Flat tires allow you the capability to drive 50
miles (80 km) at 50 mph (80 km/h) after a rapid
loss of inflation pressure. This rapid loss of
inflation is referred to as the Run Flat mode. A
Run Flat mode occurs when the tire inflation
pressure is of/or below 14 psi (96 kPa). Once a
Run Flat tire reaches the run flat mode it has
limited driving capabilities and needs to be
replaced immediately. A Run Flat tire is not
repairable.
It is not recommended driving a vehicle loaded
at full capacity or to tow a trailer while a tire is in
the run flat mode.
See the tire pressure monitoring section for
more information.
Spare Tires — If Equipped
NOTE:
For vehicles equipped with Tire Service Kit
instead of a spare tire, please refer to “Tire
Service Kit” in “What To Do In Emergencies”
for further information.
CAUTION!
Because of the reduced ground clearance,
do not take your vehicle through an auto-
matic car wash with a compact or limited-use
temporary spare installed. Damage to the
vehicle may result.
Spare Tire Matching Original Equipped Tire
And Wheel — If Equipped
Your vehicle may be equipped with a spare tire
and wheel equivalent in look and function to the
original equipment tire and wheel found on the
front or rear axle of your vehicle. This spare tire
may be used in the tire rotation for your vehicle.
If your vehicle has this option, refer to an
authorized tire dealer for the recommended tire
rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency
use only. You can identify if your vehicle is
equipped with a compact spare by looking at
the spare tire description on the Tire and Load-
ing Information Placard located on the driver’s
side door opening or on the sidewall of the tire.
Compact spare tire descriptions begin with theletter “T” or “S” preceding the size designation.
Example: T145/80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life, the original
equipment tire should be repaired (or replaced)
and reinstalled on your vehicle at the first op-
portunity.
Do not install a wheel cover or attempt to mount
a conventional tire on the compact spare wheel,
since the wheel is designed specifically for the
compact spare tire. Do not install more than one
compact spare tire and wheel on the vehicle at
any given time.
WARNING!
Compact spares are for temporary emer-
gency use only. With these spares, do not
drive more than 50 mph (80 km/h). Tempo-
rary use spares have limited tread life. When
the tread is worn to the tread wear indicators,
the temporary use spare tire needs to be
replaced. Be sure to follow the warnings,

methanol/gasoline or E-85 ethanol blends are
not the responsibility of the manufacturer.
CAUTION!
Use of fuel with Ethanol content higher than
15% may result in engine malfunction, start-
ing and operating difficulties, and materials
degradation. These adverse effects could
result in permanent damage to your vehicle.
Clean Air GasolineMany gasolines are now being blended that
contribute to cleaner air, especially in those
areas where air pollution levels are high. These
new blends provide a cleaner burning fuel and
some are referred to as “reformulated gasoline.”
The manufacturer supports these efforts toward
cleaner air. You can help by using these blends
as they become available.
MMT In GasolineMMT is a manganese containing metallic addi-
tive that is blended into some gasoline to in-
crease octane. Gasoline blended with MMTprovides no performance advantage beyond
gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces
spark plug life and reduces emission system
performance in some vehicles. The manufac-
turer recommends that gasoline without MMT
be used in your vehicle. The MMT content of
gasoline may not be indicated on the gasoline
pump; therefore, you should ask your gasoline
retailer whether or not his/her gasoline contains
MMT.
Materials Added To FuelBesides using unleaded gasoline with the
proper octane rating, gasolines that contain
detergents, corrosion and stability additives are
recommended. Using gasolines that have these
additives will help improve fuel economy, re-
duce emissions, and maintain vehicle perfor-
mance.
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these ma-
terials intended for gum and varnish removal
may contain active solvents or similar ingredi-ents. These can harm fuel system gasket and
diaphragm materials.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to pre-
vent carbon monoxide poisoning:
•Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odor-
less gas which can kill. Never run the
engine in a closed area, such as a garage,
and never sit in a parked vehicle with the
engine running for an extended period. If
the vehicle is stopped in an open area with
the engine running for more than a short
period, adjust the ventilation system to
force fresh, outside air into the vehicle.

TRAILER TOWING
In this section you will find safety tips and
information on limits to the type of towing you
can reasonably do with your vehicle. Before
towing a trailer, carefully review this information
to tow your load as efficiently and safely as
possible.
To maintain the New Vehicle Limited Warranty
coverage, follow the requirements and recom-
mendations in this manual concerning vehicles
used for trailer towing.
Common Towing DefinitionsThe following trailer towing related definitions
will assist you in understanding the following
information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers,
cargo, and tongue weight. The total load must
be limited so that you do not exceed the GVWR.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the
weight of all cargo, consumables and equip-ment (permanent or temporary) loaded in or on
the trailer in its"loaded and ready for operation"
condition.
The recommended way to measure GTW is to
put your fully loaded trailer on a vehicle scale.
The entire weight of the trailer must be sup-
ported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of
your vehicle and trailer when weighed in com-
bination.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front
and rear axles. Distribute the load over the front
and rear axles evenly. Make sure that you do
not exceed either front or rear GAWR.
WARNING!
It is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating is
exceeded.Tongue Weight (TW)
The tongue weight is the downward force ex-
erted on the hitch ball by the trailer. Tongue
weight must not exceed the lesser of either the
hitch certification rating, or the trailer tongue
chassis rating. You must consider tongue load
as part of the load on your vehicle and its
GAWR.
WARNING!
An improperly adjusted hitch system may
reduce handling, stability and braking perfor-
mance and could result in an accident. Con-
sult with your hitch and trailer manufacturer
or a reputable trailer/caravan dealer for ad-
ditional information.
Frontal Area
The frontal area is the maximum height multi-
plied by the maximum width of the front of a
trailer.
213

Trailer Sway ControlThe trailer sway control can be a mechanical
telescoping link that can be installed between the
hitch receiver and the trailer tongue that typically
provides adjustable friction associated with the
telescoping motion to dampen any unwanted
trailer swaying motions while traveling.
If equipped, the electronic Trailer Sway Control
(TSC) recognizes a swaying trailer and auto-
matically applies individual wheel brakes and/or
reduces engine power to attempt to eliminate
the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer
tongue weight, just as if it were luggage located
at a hitch ball or some other connecting point of
the vehicle. These kinds of hitches are the most
popular on the market today and they are
commonly used to tow small and medium sized
trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying
leverage through spring (load) bars. They are
typically used for heavier loads to distribute
trailer tongue weight to the tow vehicle’s frontaxle and the trailer axle(s). When used in ac-
cordance with the manufacturer’s directions, it
provides for a more level ride, offering more
consistent steering and brake control thereby
enhancing towing safety. The addition of a
friction/hydraulic sway control also dampens
sway caused by traffic and crosswinds and
contributes positively to tow vehicle and trailer
stability. Trailer sway control and a weight dis-
tributing (load equalizing) hitch are recom-
mended for heavier Tongue Weights (TW) and
may be required depending on vehicle and
trailer configuration/loading to comply with
Gross Axle Weight Rating (GAWR) require-
ments.
WARNING!
•An improperly adjusted Weight Distributing
Hitch system may reduce handling, stabil-
ity, braking performance, and could result
in a collision.
(Continued)
WARNING!(Continued)
•Weight Distributing Systems may not be
compatible with Surge Brake Couplers.
Consult with your hitch and trailer manu-
facturer or a reputable Recreational Ve-
hicle dealer for additional information.
Breakaway Cable AttachmentEuropean braking regulations for braked trailers
up to 7,700 lbs (3,500 kg), require trailers to be
fitted with either a secondary coupling or break-
away cable.
The recommended location for attaching the
normal trailer’s breakaway cable is in the
stamped slot located on the sidewall of the hitch
receiver.
214

With Attachment Point
•For detachable tow bar pass the cable
through the attachment point and clip it back
onto itself.
•
For fixed ball tow bar attach the clip directly to
the designated point. This alternative must be
specifically permitted by the trailer manufac-
turer since the clip may not be sufficiently
strong for use in the way.
Without Attachment Points
•For detachable ball tow bar you must follow
the recommended manufacturer or supplier
procedure.•For fixed ball tow bar loop the cable around
the neck of the tow ball. If you fit the cable
like this, use a single loop only.
Trailer Towing Weights (Maximum
Trailer Weight Ratings)
The following chart provides the maximum
trailer weight ratings towable for your given
drivetrain.
215

Engine/Transmission Frontal Area Max. GTW (Gross Trailer Wt.) Max. Tongue Wt. (See Note 1)
2.0L Auto/Man 22 sq ft (2.04 sq m) 2,645 lbs (1,199 kg) 132 lbs (59 kg)
2.4L Auto/Man 22 sq ft (2.04 sq m) 3,307 lbs (1,500 kg) 165 lbs (74 kg)
When towing a trailer the technically permissible laden weight may be exceeded by not more than 10% or 220 lbs (99 kg), whichever is lower pro-
vided that the operating speed is restricted to 62 mph (100 km/h) or less.
Refer to local laws for maximum trailer towing speeds
Note 1 – The trailer tongue weight must be
considered as part of the combined weight of
occupants and cargo, and should never exceed
the weight referenced on the Tire and Loading
Information placard.
Trailer And Tongue WeightNever exceed the maximum tongue weight
stamped on your trailer hitch.
Consider the following items when computing
the weight on the rear axle of the vehicle:
•The tongue weight of the trailer.
•The weight of any other type of cargo or
equipment put in or on your vehicle.
•The weight of the driver and all passengers.NOTE:
Remember that everything put into or on the
trailer adds to the load on your vehicle. Also,
additional factory-installed options, or
dealer-installed options, must be consid-
ered as part of the total load on your vehicle.
Refer to the Tire and Loading Information
placard, located on the drivers door pillar,
for the maximum combined weight of occu-
pants and cargo for your vehicle.
Towing RequirementsTo promote proper break-in of your new vehicle
drivetrain components the following guidelines
are recommended:
CAUTION!
•Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is
driven. The engine, axle or other parts
could be damaged.
•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.
216

WARNING!
Improper towing can lead to an injury acci-
dent. Follow these guidelines to make your
trailer towing as safe as possible:
•Make certain that the load is secured in the
trailer and that it will not shift during travel.
When trailering cargo that is not fully se-
cured, 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.
•All trailer hitches should be professionally
installed on your vehicle.
•When hauling cargo or towing a trailer, do
not overload your vehicle or trailer. Over-
loading can cause a loss of control, poor
performance, or damage to brakes, axle,
engine, transmission, steering, suspen-
sion, chassis structure, or tires.
(Continued)
WARNING!(Continued)
•Safety chains must always be used be-
tween your vehicle and trailer. Always con-
nect the chains to the frame or hook re-
tainers 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 park-
ing brake on the tow vehicle. Always, block
or"chock"the trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed be-
tween the tow vehicle and the trailer
such that the following four ratings are
not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch
utilized.Towing Requirements — Tires
•Do not attempt to tow a trailer while using a
compact spare tire.
•Proper tire inflation pressures are essential
for the safe and satisfactory operation of your
vehicle. Refer to “Tires – General Informa-
tion” in “Starting and Operating” for proper
tire inflation procedures.
•Check the trailer tires for proper tire inflation
pressures before trailer usage.
•Check for signs of tire wear or visible tire
damage before towing a trailer. Refer to
“Tires – General Information” in “Starting and
Operating” for the proper inspection
procedure.
•When replacing tires, refer to “Tires – Gen-
eral Information” in “Starting and Operating”
for proper tire replacement procedures. Re-
placing tires with a higher load carrying ca-
pacity will not increase the vehicle’s GVWR
and GAWR limits.
217

Towing Requirements — Trailer Brakes
–Donotinterconnect the hydraulic brake sys-
tem or vacuum system of your vehicle with
that of the trailer. This could cause inad-
equate braking and possible personal injury.
– When towing a trailer equipped with a hy-
draulic surge actuated brake system, an
electronic brake controller is not required.
– Trailer brakes are recommended for trailers
over 1,000 lbs (453 kg) and required for
trailers in excess of 1,653 lbs (749 kg).
CAUTION!
If the trailer weighs more than 1,000 lbs
(453 kg) loaded, it should have its own
brakes and they should be of adequate
capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake
pedal effort, and longer stopping distances.
WARNING!
•Do not connect trailer brakes to your vehi-
cle’s hydraulic brake lines. It can overload
your brake system and cause it to fail. You
might not have brakes when you need
them and could have an accident.
•Towing any trailer will increase your stop-
ping distance. When towing, you should
allow for additional space between your
vehicle and the vehicle in front of you.
Failure to do so could result in an accident.
Towing Requirements – Trailer Lights And
Wiring
Whenever you pull a trailer, regardless of the
trailer size, stop lights and turn signals on the
trailer are required for motoring safety.The Trailer Tow Package may includea7ora
13–pin wiring harness. Use a factory approved
trailer harness and connector.
NOTE:
Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to
the vehicle but you must mate the harness to a
trailer connector.

Towing TipsBefore setting out on a trip, practice turning,
stopping and backing the trailer in an area away
from heavy traffic.
Manual Transmission — If Equipped
If using a manual transmission vehicle for trailer
towing, all starts must be in first gear to avoid
excessive clutch slippage.
Automatic Transmission — If Equipped
The DRIVE range can be selected when towing.
However, if frequent shifting or changes in
engine speed occur while in DRIVE, use the
AutoStick shift control to manually select a
lower gear ratio.
NOTE:
Using a lower gear ratio while operating the
vehicle under heavy loading conditions, will
improve performance and extend transmis-
sion life by reducing excessive shifting and
heat buildup. This action will also provide
better engine braking.
If you REGULARLY tow a trailer for more than
45 minutes of continuous operation, then
change the transmission fluid and filter asspecified for"police, taxi, fleet, or frequent
trailer towing."Refer to the “Maintenance
Schedule” for the proper maintenance intervals.
AutoStick
•When using the AutoStick shift control, select
the highest gear that allows for adequate
performance and avoids frequent downshifts.
For example, choose"4"if the desired speed
can be maintained. Choose"3"or"2"if
needed to maintain the desired speed.
•To prevent excess heat generation, avoid
continuous driving at high RPM. Reduce
vehicle speed as necessary to avoid ex-
tended driving at high RPM. Return to a
higher gear or vehicle speed when grade and
road conditions allow.
Electronic Speed Control — If Equipped
•Do not use in hilly terrain or with heavy loads.
•When using the speed control, if you experi-
ence 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.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
When stopped for short periods of time, shift the
transmission into NEUTRAL and increase en-
gine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
