Hill Start Assist (HSA)
The HSA system is designed to mitigate roll back from a
complete stop while on an incline. If the driver releases
the brake while stopped on an incline, HSA will continue
to hold the brake pressure for a short period. If the driver
does not apply the throttle before this time expires, the
system will release brake pressure and the vehicle will
roll down the hill as normal.
The following conditions must be met in order for HSA to
activate:
•The feature must be enabled.
• The vehicle must be stopped.
• Park brake must be off.
• Driver door must be closed.
• The vehicle must be on a sufficient grade. •
The gear selection must match vehicle uphill direction
(i.e., vehicle facing uphill is in forward gear; vehicle
backing uphill is in REVERSE gear).
• HSA will work in REVERSE gear and all forward
gears. The system will not activate if the transmission
is in PARK or NEUTRAL. For vehicles equipped with
a manual transmission, if the clutch is pressed, HSA
will remain active.
WARNING!
There may be situations where the Hill Start Assist
(HSA) will not activate and slight rolling may occur,
such as on minor hills or with a loaded vehicle, or
while pulling a trailer. HSA is not a substitute for
active driving involvement. It is always the driver ’s
responsibility to be attentive to distance to other
vehicles, people, and objects, and most importantly

brake operation to ensure safe operation of the ve-
hicle under all road conditions. Your complete atten-
tion is always required while driving to maintain
safe control 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 activated and
deactivated with the brake switch. If so, there may

WARNING! (Continued)
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 acceleration, manually ac-
tivate 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 transmission 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.

NOTE:
•For vehicles with multiple partial ESC modes a mo-
mentary button push will toggle the ESC mode. Mul-
tiple momentary button pushed may be required to
return to ESC On.
• Trailer Sway control (TSC) is disabled when the ESC
system is in the “Partial Off” mode.
• ESC Sport andESC Track (If equipped) are ESC
partial off mode(s).
Full Off – If Equipped
This mode is intended for off-highway or off-road use
only and should not be used on any public roadways. In
this mode, TCS and ESC features are turned OFF. To enter
the “Full Off” mode, push and hold the “ESC Off” switch
for five seconds while the vehicle is stopped with the
engine running. After five seconds, a chime will sound,
the “ESC Off Indicator Light” will illuminate, and the “ESC OFF” message will display in the Driver Informa-
tion Display (DID). To turn ESC ON again, momentarily
push the “ESC Off” switch.
NOTE:
System may switch from ESC Full Off to Partial
mode when vehicle exceeds a predetermined speed.
When the vehicle speed slows below the predetermined
speed the system will return to ESC Full Off.
ESC modes may also be affected by drive modes – if
equipped.
WARNING!
• In the ESC “Full Off” mode, the engine torque
reduction and stability features are disabled.
Therefore, enhanced vehicle stability offered by
the ESC system is unavailable. In an emergency
evasive maneuver, the ESC system will not engage

NOTE:Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWRs) for the front and rear
axles must not be exceeded. For further information on
GAWRs, vehicle loading, and trailer towing, refer to
“Vehicle Loading” in the “Starting And Operating” sec-
tion of this manual.
To determine the maximum loading conditions of your
vehicle, locate the statement “The combined weight of
occupants and cargo should never exceed XXX lbs or
XXX kg” on the Tire and Loading Information placard.
The combined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never exceed
the weight referenced here. Steps For Determining Correct Load Limit
1. Locate the statement “The combined weight of occu-
pants and cargo should never exceed XXX lbs or
XXX kg” on your vehicle’s placard.
2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and pas- sengers from XXX lbs or XXX kg.

4. The resulting figure equals the available amount ofcargo and luggage load capacity. For example, if
“XXX” amount equals 1,400 lbs (635 kg) and there will
be five 150 lb (68 kg) passengers in your vehicle, the
amount of available cargo and luggage load capacity
is 650 lbs (294 kg) (since 5 x 150 lbs (68 kg) = 750 lbs
(340 kg), and 1400 lbs (635 kg) – 750 lbs (340 kg) =
650 lbs [294 kg]).
5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not
safely exceed the available cargo and luggage load
capacity calculated in step 4. NOTE:
•
If your vehicle will be towing a trailer, load from your
trailer will be transferred to your vehicle. The follow-
ing table shows examples on how to calculate total
load, cargo/luggage, and towing capacities of your
vehicle with varying seating configurations and num-
ber and size of occupants. This table is for illustration
purposes only and may not be accurate for the seating
and load carry capacity of your vehicle.
• For the following example, the combined weight of
occupants and cargo should never exceed 865 lbs
(392 kg).

While studded tires improve performance on ice, skid
and traction capability on wet or dry surfaces may be
poorer than that of non-studded tires. Some states pro-
hibit studded tires; therefore, local laws should be
checked before using these tire types.
Run Flat Tires — If Equipped
Run 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 immedi-
ately. 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 infor-
mation.
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 automatic 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

•Refer to the “Vehicle Certification Label” affixed to the
rear of the driver’s door for your vehicle’s GVWR and
GAWRs.
• Refer to the “Tire Placard” for your vehicle’s proper
tire pressure.
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 recommendations in this
manual concerning vehicles used for trailer towing.
Common Towing Definitions
The 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. Refer to “Vehicle Loading/Vehicle
Certification Label” in “Starting And Operating” for
further information.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or tem-
porary) loaded in or on the trailer in its loaded and
ready for operation condition.
464 STARTING AND OPERATING
Page 467 of 620

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 supported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of your vehicle
and trailer when weighed in combination.
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. Refer to “Vehicle Loading/Vehicle Certifica-
tion Label” in “Starting And Operating” for further
information.
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. You could lose
control of the vehicle and have a collision.
Tongue Weight (TW)
The tongue weight is the downward force exerted on the
hitch ball by the trailer. You must consider this as part of
the load on your vehicle.
Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
