Some models may also come equipped
with a sport mode which allows the driver
to reduce normal AdvanceTrac system
intervention and provide a more spirited
driving experience. To enter sport mode,
toggle the stability control button twice
rapidly. The message appears in the
information display that the system is now
in sport mode.
For vehicles equipped with the selectable
drive mode feature, AdvanceTrac sport
mode is not available. You can utilize the
performance oriented AdvanceTrac mode
by selecting track drive mode. In this mode,
AdvanceTrac intervention is reduced and
tuned specifically for track use only and is
not for use on public roads. In all of the
selectable drive modes, you can disable
traction control and AdvanceTrac with the
AdvanceTrac switch.
Line Lock (If Equipped)
Line Lock is a feature intended for use at
tracks only and should not be used on
public roadways. Use of this feature will
result in significantly increased rear tire
wear. It is intended to condition the rear
tires to maximum traction prior to track
use. Line Lock maintains brake force at the
front wheels, allowing the rear wheels to
spin with minimal vehicle movement.
This feature is located in the Track Apps
menu. Make selections through the 5-way
information display control and OK button
located on the steering wheel.
Using Line Lock
There are three Line Lock stages:
• Initiated.
• Engaged.
• Off. Initiating Line Lock
The initiation stage verifies that the vehicle
is ready for Line Lock function, and
confirms driver intent. Follow the prompts
in the information display in to initiate Line
Lock.
The following conditions must be met to
initialize Line Lock:
•
The vehicle is on a level surface.
• The engine is running.
• The vehicle is traveling less than 25
mph (40 km/h).
• Selectable Drive Mode is not in wet
mode (if equipped).
• There are no AdvanceTrac faults.
If you want to cancel Line Lock once it is
initialized, press the left information
display control. Once initiated, Line Lock
is prepared for activation and will remain
initiated up to 25 mph (40 km/h). If vehicle
speed exceeds 25 mph (40 km/h), Line
Lock will be automatically canceled.
Engaging Line Lock
Follow the prompts in the information
display to engage Line Lock after it is
initialized. To engage, firmly apply the
brakes. Then press the OK button. Once
engaged, release the brake pedal. The
front brakes will remain applied and the
rear brakes will release. At this point, the
engagement timer is initiated and shown
on the driver information display.
The following conditions must be met to
engage Line Lock:
• The vehicle is on a level surface.
• The engine is running.
• The vehicle is stopped.
• The parking brake is not applied.
• The driver door is closed.
• The transmission is in a forward gear.

Disengaging the System
Press the brake pedal, press CNCL, or
press the clutch pedal (if equipped). The
last set speed displays in grey but will not
erase.
Overriding the System WARNING
Whenever the driver is overriding the
system by pressing the accelerator
pedal, the system will not
automatically apply the brakes to maintain
separation from any vehicle ahead. You can override the set speed and gap
distance by pressing the accelerator pedal.
When you override the system,
the green indicator light
illuminates and the lead vehicle
graphic does not show in the
information display.
The system will resume operation when
you release the accelerator pedal. The
vehicle speed will decrease to the set
speed, or a lower speed if following a
slower vehicle.
Changing the Set Speed
• Accelerate or brake to the desired
speed, then press and release
SET+.
• Press and hold SET+ or SET- until the
desired set speed shows on the
information display. The vehicle speed
will gradually change to the selected
speed.
• Press and release
SET+ or SET-. The
set speed will change in approximately
1 mph (2 km/h) increments.
The system may apply the brakes to slow
the vehicle to the new set speed. The set
speed will display continuously in the
information display while the system is
active. Resuming the Set Speed
Note:
Only use resume if you are aware of
the set speed and intend to return to it.
Press and release
RES. The vehicle will
return to the previously set speed. The set
speed will display continuously in the
information display while the system is
active.
Automatic Cancellation
The system is not functional at vehicle
speeds below 12 mph (20 km/h). An
audible alarm will sound and the
automatic braking releases if the vehicle
drops below this speed. The system will
cancel at low speeds if you switch off
electronic stability control.
Hilly Condition Usage
Note: An audible alarm will sound and the
system will shut down if it is applying brakes
for an extended period of time. This allows
the brakes to cool down. The system will
function normally again when the brakes
have cooled down.
You should select a lower gear position
when the system is active in situations
such as prolonged downhill driving on
steep grades, for example in mountainous
areas. The system needs additional engine
braking in these situations to reduce the
load on the vehicle ’s regular brake system
to prevent them from overheating.
Switching the System Off
Note: The set speed memory erases when
you switch off the system.
Press and release
OFF or turn off the
ignition.

BLIND SPOT INFORMATION
SYSTEM
Blind Spot Information System
(BLIS
™) with Cross Traffic Alert
(If Equipped) WARNING
To help avoid injuries, NEVER use the
Blind Spot Information System as a
replacement for using the interior
and exterior mirrors and looking over your
shoulder before changing lanes. The Blind
Spot Information System is not a
replacement for careful driving. The Blind Spot Information System aids
you in detecting vehicles that may have
entered the blind spot zone (A). The
detection area is on both sides of your
vehicle, extending rearward from the
exterior mirrors to approximately 10 ft
(3 m) beyond the bumper. The system
alerts you if certain vehicles enter the blind
spot zone while driving. WARNING
To help avoid personal injury, NEVER
use the cross traffic alert system as
a replacement for using the interior
and exterior mirrors and looking over your
shoulder before backing out of a parking
space. Cross traffic alert is not a
replacement for careful driving. Cross traffic alert warns you of vehicles
approaching from the sides when the
transmission is in reverse (R).
Note:
The Blind Spot Information System
does not prevent contact with other vehicles
or objects; nor does it detect parked
vehicles, people, animals or infrastructure
(fences, guardrails or trees). It only alerts
you to vehicles in the blind zones.
Note: When a vehicle passes quickly
through the blind zone, typically fewer than
two seconds, the system does not trigger.
Using the Systems
The Blind Spot Information System turns
on when you start the engine and you drive
your vehicle forward above
5 mph
(8 km/h), it remains on while the
transmission is in drive (D) or neutral (N).
If shifted out of drive (D) or neutral (N),
the system enters cross traffic alert mode.
Once shifted back into drive (D), the Blind
Spot Information System turns back on
when you drive your vehicle above
5 mph
(8 km/h).
Note: The Blind Spot Information System
does not function in reverse (R) or park (P).
Note: Cross traffic alert detects
approaching vehicles and bicycles from up
to
46 ft (14 m) away though coverage
decreases when the sensors are blocked.
Reversing slowly helps increase the
coverage area and effectiveness.

All other system faults will display only
with a message in the information display.
See Information Messages (page 91).
Switching the Systems Off and On
You can temporarily switch off one or both
systems in the information display. See
General Information
(page 83). When
you switch off the Blind Spot Information
System, you will not receive alerts and the
information display will display a system
off message.
Note: The cross traffic alert system always
turns on whenever the ignition is switched
on. However, the Blind Spot Information
System will remember the last selected on
or off setting.
You cannot switch one or both systems
off when MyKey is used.
See Principle of
Operation (page 50).
You can also have one or both systems
switched off permanently at an authorized
dealer. Once switched off, only an
authorized dealer can switch the system
back on.
STEERING
Electric Power Steering WARNINGS
The electric power steering system
has diagnostic checks that
continuously monitor the system to
ensure proper operation. When a system
error is detected a steering message will
appear in the information display. The electric power steering system
has diagnostic checks that
continuously monitor the system to
ensure proper operation of the electronic
system. When an electronic error is
detected, a message will be displayed in
the information display. If this happens,
stop the vehicle in a safe place, and turn WARNINGS
off the engine. After at least 10 seconds,
reset the system by restarting the engine,
and watch the information display for a
steering message. If a steering message
returns, or returns while driving, take the
vehicle to your dealer to have it checked. Obtain immediate service if a system
error is detected. You may not notice
any difference in the feel of your
steering, but a serious condition may exist.
Failure to do so may result in loss of
steering control. Your vehicle has an electric power steering
system. There is no fluid reservoir to check
or fill.
If your vehicle loses electrical power while
you are driving (or if you switch the ignition
off), you can steer your vehicle manually,
but it takes more effort. Extreme
continuous steering may increase the effort
it takes for you to steer. This occurs to
prevent internal overheating and
permanent damage to your steering
system. If this should occur, you will neither
lose the ability to steer your vehicle
manually nor will it cause permanent
damage. Typical steering and driving
maneuvers allows the system to cool and
steering assist to return to normal.
Steering Tips
If the steering wanders or pulls, check for:
•
An improperly inflated tire.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
A high crown in the road or high crosswinds
may also make the steering seem to
wander or pull.

•
Track – Provides a performance driving
experience. The engine responds
directly to your inputs and takes on a
more powerful tone. Track mode is for
use when pure performance is desired.
A performance oriented AdvanceTrac
mode is automatically utilized when
Track drive mode is selected. In this
mode, AdvanceTrac intervention is
reduced and tuned specifically for track
usage only and is not intended for
public roads. See Using Stability
Control (page 144).
• Snow/Wet - Provides a confident
handling driving experience during poor
weather. This mode provides an
confident drive experience and a direct

sacrificing any of the composure
demanded from your vehicle.
Note: Selectable driving modes has
diagnostic checks that continuously monitor
the system to ensure proper operation.
Certain selectable drive modes will not be
available based on gear shifter position (for
example, Snow/Wet is not available while
in sport (S) position). If a selected mode is
unavailable due to a system fault or change
in gear shifter position, the selected mode
will default to Normal.
Selectable Steering
Note: The steering setting defaults to
Normal if the battery is disconnected or
removed. To change the steering feel,
toggle the switch on the
instrument panel. The first press
illuminates the selected mode, subsequent
presses will change the selected mode. Modes:
•
Normal - Default factory setting.
• Sport - Slightly higher effort required
for steering with more road force felt
through the steering wheel.
• Comfort - Slightly less effort required
for steering with less road force felt
through the steering wheel.
After selecting the desired setting, you may
feel a soft feedback bump in the steering
wheel when the changeover occurs.
Note: If your vehicle is equipped with the
selectable drive modes feature, the steering
feel will change when you select a new drive
mode. You can override this automatic
selection by pressing the steering
button/switch.

WARNING
Exceeding the Safety
Compliance Certification
Label vehicle weight rating limits
could result in substandard
vehicle handling or performance,
engine, transmission and/or
structural damage, serious
damage to the vehicle, loss of
control and personal injury. Maximum Loaded Trailer
Weight - The highest possible
weight of a fully loaded trailer the
vehicle can tow. Consult an
authorized dealer (or the RV and
Trailer Towing Guide available at
an authorized dealer) for more
detailed information. WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
Safety Compliance Certification
Label. Do not use replacement tires
with lower load carrying
capacities than the original tires
because they may lower your
vehicle ’s GVWR and GAWR
limitations. Replacement tires
with a higher limit than the original
tires do not increase the GVWR
and GAWR limitations. Exceeding any vehicle weight
rating limitation could result
in serious damage to your vehicle,
personal injury or both. Steps for determining the
correct load limit:
1. Locate the statement "The
combined weight of occupants
and cargo should never exceed
XXX kg or XXX lb." 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 passengers
from XXX kg or XXX lb.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For
example, if the “XXX” amount
equals 1,400 lb. and there will
be five 150 lb. passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lb.
(1400-750 (5 x 150) = 650 lb.)
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.
6. If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your
vehicle. Consult this manual to
determine how this reduces the
available cargo and luggage
load capacity of your vehicle.

WARNING
Exceeding the Safety Compliance
Certification Label vehicle weight
rating limits could result in
substandard vehicle handling or
performance, engine, transmission and/or
structural damage, serious damage to the
vehicle, loss of control and personal injury. GCW (Gross Combined Weight)
- is the Gross Vehicle Weight plus
the weight of the fully loaded
trailer.
GCWR (Gross Combined
Weight Rating) - is the maximum
allowable weight of the vehicle
and the loaded trailer, including
all cargo and passengers, that the
vehicle can handle without risking
damage. (Important: The towing
vehicle ’s braking system is rated
for operation at Gross Vehicle
Weight Rating, not at Gross
Combined Weight Rating.)
Separate functional brakes should
be used for safe control of towed
vehicles and for trailers where the
Gross Combined Weight of the towing vehicle plus the trailer
exceed the Gross Vehicle Weight
Rating of the towing vehicle.
The
Gross Combined Weight must
never exceed the Gross
Combined Weight Rating.
Maximum Loaded Trailer
Weight -
is the highest possible
weight of a fully loaded trailer the
vehicle can tow. It assumes a
vehicle with mandatory options,
driver and front passenger weight
(150 pounds [68 kilograms]
each), no cargo weight (internal
or external) and a tongue load of
10– 15% (conventional trailer) or
king pin weight of 15– 25% (fifth
wheel trailer). Consult an
authorized dealer (or the RV and
Trailer Towing Guide available at
an authorized dealer) for more
detailed information.

TOWING A TRAILER
WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
certification label. Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of your vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of vehicle control,
vehicle rollover and personal
injury. Note:
There may be electrical
items such as fuses or relays that
can affect trailer towing operation.
See Fuses (page 202).
The load capacity of your vehicle
is designated by weight not
volume. You may not necessarily
be able to use all available space
when loading your vehicle or
trailer.
Towing a trailer places extra load
on the engine, transmission, axle,
brakes, tires, and suspension.
Inspect these components before,
during and after towing. Load Placement
To help minimize how trailer
movement affects the vehicle
when driving:
•
Load the heaviest items closest
to the trailer floor.
• Load the heaviest items in the
center of the left and right side
trailer tires.
• Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
• Select a tow bar with the
correct rise or drop. When both
the loaded vehicle and trailer
are connected, the trailer frame
should be level, or slightly
angled down toward the
vehicle, when viewed from the
side.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in the Load Carrying
chapter. See
Load Limit (page
168). You can also find the
information in the RV & Trailer
Towing Guide, available at an
authorized dealer.

When Towing a Trailer
•
Do not drive faster than 70 mph (113
km/h) during the first 500 miles (800
kilometers).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 miles (80
kilometers).
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in park (P) (automatic
transmission) or neutral (manual
transmission) to aid engine and
transmission cooling and to help air
conditioning performance.
• Switch off the speed control with
heavy loads or in hilly terrain. The
speed control may turn off
automatically when you are towing on
long, steep grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission in park (P) or manual transmission in a
low gear. 4. Place wheel chocks in front and back
of the trailer wheels. (Chocks not
included with vehicle.)
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than 6 inches (15 centimeters) above
the bottom edge of the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Any time the rear axle submerges in water,
replace the rear axle lubricant. Water may
contaminate the rear axle lubricant, which
is not a normal maintenance inspection
item unless there is a possibility of a leak
or other axle repair is required.
