TOW N GO — IF EQUIPPED
Tow N Go combines the capabilities of the vehicle
control systems, along with driver input, to provide
optimum performance for road conditions.
Push any one of the four drive mode buttons to
select the desired mode.

Drive Mode Buttons
Tow N Go consists of the following positions:TRACK
– Track mode optimizes settings for
transmission, engine, driveline, and suspension
in order to maximize vehicle performance. Also
the electric power steering offers more feed -
back of the tire gripping the road. This feature
will reset to AUTO upon an ignition cycle. To turn
off Electronic Stability Control (ESC)
Ú page 192.
SPORT – Dry weather, on-road calibration.
Performance based tuning that provides a
rear-wheel drive feel but with improved handling
and acceleration over a two-wheel drive vehicle.
This feature will reset to AUTO upon an ignition
cycle.
TOW – Tow drive mode also optimizes the trans -
mission shifting for towing, as well as maxi -
mizing straight line traction by optimizing
driveline settings on AWD system. Use this
mode for towing/hauling. Vehicle suspension
will go to SPORT mode. Trailer Sway Control
(TSC) is enabled in the ESC system. This feature
will reset to AUTO upon an ignition cycle.
SNOW – Tuning set for additional stability in
inclement weather. Use on and off-road on
loose traction surfaces such as snow. This
feature will reset to AUTO upon an ignition cycle.
GUIDELINES FOR TRACK USE
If your vehicle is equipped with Drive Modes,
they will alter the vehicle’s performance in
various driving situations. It is recommended
that your vehicle operates in SPORT or TRACK
modes during the track event.
Prior to each track event, verify all fluids are at
the correct levels.
Prior to each track event, verify the front and
rear brake pads have more than half pad thick -
ness remaining. If the brake pads require
changing, complete a brake burnish procedure
prior to track outing at full pace.
NOTE:Use of DOT 4 brake fluid is suggested for extended
track usage due to increased thermal capacity.
At the conclusion of each track event, it is
recommended that a brake bleed procedure is
performed to maintain the pedal feel and stop -
ping capability of your Brembo High Perfor -
mance brake system.
It is recommended that each track outing
should end with a minimum of one cooldown lap
using minimal braking.
It is recommended that the suspension system,
brake system, prop shaft, and half shaft boots
be checked for wear or damage after every track
event.

To resume a previously set speed, push the RES
button and release. Resume can be used at any
speed above 20 mph (32 km/h).
To Deactivate
A tap on the brake pedal, pushing the CANC button,
or normal brake pressure while slowing the vehicle
will deactivate the Cruise Control system without
erasing the set speed from memory.
The following conditions will also deactivate the
Cruise Control without erasing the set speed from
memory:
Vehicle parking brake is applied
Stability event occurs
Gear selector is moved out of DRIVE
Engine overspeed occurs
Pushing the on/off button or placing the ignition in
the OFF position will erase the set speed from
memory.
ADAPTIVE CRUISE CONTROL (ACC) —
I
F EQUIPPED
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while
traveling on highways and major roadways.
However, it is not a safety system and not designed
to prevent collisions. The Cruise Control function
performs differently Ú page 119.
ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your Cruise Control. ACC
utilizes a radar sensor and a forward facing
camera designed to detect a vehicle directly ahead
of you.
NOTE:
If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or acceleration (not to
exceed the original set speed) automatically to
maintain a preset following distance, while
matching the speed of the vehicle ahead.
Any chassis/suspension or tire size modifica -
tions to the vehicle will affect the performance
of the Adaptive Cruise Control and Forward Colli -
sion Warning system.
Fixed Speed Cruise Control (ACC not enabled)
will not detect vehicles directly ahead of you.
Always be aware of the mode selected
Ú page 327.
WARNING!
Adaptive Cruise Control (ACC) is a conve -
nience system. It is not a substitute for active
driver involvement. It is always the driver’s
responsibility to be attentive of road, traffic,
and weather conditions, vehicle speed,
distance to the vehicle ahead; and, most
importantly, brake operation to ensure safe
operation of the vehicle under all road condi -
tions. Your complete attention is always
required while driving to maintain safe control
of your vehicle. Failure to follow these warn -
ings can result in a collision and death or
serious personal injury.
The ACC system:
Does not react to pedestrians, oncoming
vehicles, and stationary objects (e.g., a
stopped vehicle in a traffic jam or a
disabled vehicle).
Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance condi -
tions.
Does not always fully recognize complex
driving conditions, which can result in
wrong or missing distance warnings.

VEHICLE LOADING
CERTIFICATION LABEL
As required by National Highway Traffic Safety
Administration regulations, your vehicle has a
certification label affixed to the driver's side door or
pillar.
This label contains the month and year of
manufacture, Gross Vehicle Weight Rating
(GVWR), front and rear Gross Axle Weight Rating
(GAWR), and Vehicle Identification Number (VIN). A
Month-Day-Hour (MDH) number is included on this
label and indicates the Month, Day and Hour of
manufacture. The bar code that appears on the
bottom of the label is your VIN.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your
vehicle including driver, passengers, vehicle,
options and cargo. The label also specifies
maximum capacities of front and rear (GAWR).
Total load must be limited so GVWR and front and
rear GAWR are not exceeded.
Payload
The payload of a vehicle is defined as the allowable
load weight a truck can carry, including the weight
of the driver, all passengers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the
front and rear axles. The load must be distributed
in the cargo area so that the GAWR of each axle is
not exceeded.
Each axle GAWR is determined by the components
in the system with the lowest load carrying capacity
(axle, springs, tires or wheels). Heavier axles or
suspension components sometimes specified by
purchasers for increased durability does not
necessarily increase the vehicle's GVWR.
Tire Size
The tire size on the Vehicle Certification Label
represents the actual tire size on your vehicle.
Replacement tires must be equal to the load
capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire
size listed.
Inflation Pressure
This is the cold tire inflation pressure for your
vehicle for all loading conditions up to full GAWR.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the “Malfunc -
tion Indicator Light” to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.

TRAILER AND TONGUE WEIGHT
Never exceed the maximum tongue weight
stamped on your bumper or trailer hitch.

Weight Distribution
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 equip
-
ment 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 considered as part of the total load on
your vehicle. Refer to the Tire And Loading Infor -
mation placard for the maximum combined weight
of occupants and cargo for your vehicle
Ú page 300.
TOWING REQUIREMENTS
To promote proper break-in of the new vehicle
drivetrain components, the following guidelines
are recommended. Perform the maintenance listed in Scheduled
Servicing Ú
page 264. When towing a trailer,
never exceed the GAWR or GCWR ratings.
CAUTION!
Always load a trailer with 60% of the weight in
the front of the trailer. This places 10% of the
GTW on the tow hitch of your vehicle. Loads
balanced over the wheels or heavier in the rear
can cause the trailer to sway severely side 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.
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.
WARNING!
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 a collision.
When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading
can cause a loss of control, poor performance
or damage to brakes, axle, engine, transmis -
sion, steering, suspension, chassis structure
or tires.
CAUTION!

ESC Operating Modes
Depending upon model and mode of operation, the
ESC system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC.
Whenever the vehicle is started, the ESC system
will be in this mode. This mode should be used for
most driving conditions. Alternate ESC modes
should only be used for specific reasons as noted
in the following paragraphs. Partial Off
This mode may be useful if the vehicle becomes
stuck. This mode may modify TCS and ESC
thresholds for activation, which allows for more
wheel spin than normally allowed.
To enter the “Partial Off” mode, momentarily push
the ESC OFF button and the ESC OFF Indicator
Light will illuminate. To turn the ESC on again,
momentarily push the ESC OFF button and the
ESC OFF Indicator Light will turn off.
NOTE:For vehicles with multiple partial ESC modes, the
push and release of the button will toggle the
ESC modes. Multiple attempts may be required to
return to "ESC On" mode.
WARNING!
Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road condi
-
tions. ESC cannot prevent accidents, including
those resulting from excessive speed in turns,
driving on very slippery surfaces, or hydro -
planing. ESC also cannot prevent accidents
resulting from loss of vehicle control due to
inappropriate driver input for the conditions.
Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ESC
equipped vehicle must never be exploited in a
reckless or dangerous manner which could
jeopardize the user’s safety or the safety of
others.Vehicle modifications, or failure to properly
maintain your vehicle, may change the
handling characteristics of your vehicle, and
may negatively affect the performance of the
ESC system. Changes to the steering system,
suspension, braking system, tire type and size
or wheel size may adversely affect ESC perfor -
mance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any
vehicle modification or poor vehicle mainte -
nance that reduces the effectiveness of the
ESC system can increase the risk of loss of
vehicle control, vehicle rollover, personal
injury and death.
WARNING!
WARNING!
When in “Partial Off” mode, the TCS function -
ality of ESC, except for the limited slip feature
described in the TCS section, has been
disabled and the ESC OFF Indicator Light will
be illuminated. When in “Partial Off” mode,
the engine power reduction feature of TCS is
disabled, and the enhanced vehicle stability
offered by the ESC system is reduced.
Trailer Sway Control (TSC) is disabled when
the ESC system is in the “Partial Off” mode.

262IN CASE OF EMERGENCY
Proper towing or lifting equipment is required to
prevent damage to your vehicle. Use only tow bars
and other equipment designed for this purpose,
following equipment manufacturer’s instructions.
Use of safety chains is mandatory. Attach a tow bar
or other towing device to main structural members
of the vehicle, not to fascia/bumpers or associated
brackets. State and local laws regarding vehicles
under tow must be observed.
If you must use the accessories (wipers,
defrosters, etc.) while being towed, the ignition
must be in the ON/RUN mode, not the ACC mode.
If the vehicle's battery is discharged, instructions
on shifting the automatic transmission out of PARK
(P) in order to move the vehicle can be found on
Ú page 258.
REAR WHEEL DRIVE MODELS
FCA US LLC recommends towing your vehicle with
all four wheels OFF the ground using a flatbed.
If flatbed equipment is not available, and the
transmission is operable, the vehicle may be towed
(with rear wheels on the ground) under the
following conditions:
The transmission must be in NEUTRAL (N).
For instructions on shifting the transmission to
NEUTRAL (N) when the engine is off
Ú page 258.
The towing speed must not exceed
30 mph (48 km/h).
The towing distance must not exceed
30 miles (48 km). If the transmission is not operable, or the vehicle
must be towed faster than 30 mph (48 km/h) or
farther than 30 miles (48 km), tow with the rear
wheels
OFF the ground. Acceptable methods are to
tow the vehicle on a flatbed, or with the front
wheels raised and the rear wheels on a towing
dolly, or (when using a suitable steering wheel
stabilizer to hold the front wheels in the straight
position) with the rear wheels raised and the front
wheels ON the ground.
CAUTION!
Do not use sling type equipment when towing.
Vehicle damage may occur.
When securing the vehicle to a flat bed truck,
do not attach to front or rear suspension
components. Damage to your vehicle may
result from improper towing.
CAUTION!
Towing faster than 30 mph (48 km/h) or
farther than 30 miles (48 km) with rear
wheels on the ground can cause severe trans -
mission damage. Damage from improper
towing is not covered under the New Vehicle
Limited Warranty.
