16 GETTING TO KNOW YOUR VEHICLE

Turn Signals
Move the multifunction lever up or down and the arrows
on each side of the instrument cluster flash to show proper
operation of the front and rear turn signal lights.
NOTE:
•If either light remains on and does not flash, or there is
a very fast flash rate, check for a defective outside light
bulb. If an indicator fails to light when the lever is
moved, it would suggest that the indicator bulb is
defective. •
A tone will chime if the turn signals are left on for more
than 1 mile (2 km).
Lane Change Assist — If Equipped
Tap the lever up or down once, without moving beyond
the detent, and the turn signal (right or left) will flash three
times then automatically turn off.
Lights-On Reminder
If the headlights, parking lights or cargo lights are left on
after the ignition is turned OFF, a chime will sound when
the driver ’s door is opened.
INTERIOR LIGHTS
Courtesy/Reading Lights
Two courtesy/reading lights are located in the bottom of
the rearview mirror. You can turn these lights on and off
from the switches in the mirror or from the dimmer control
in the multifunction lever. These lights are also controlled
automatically by the Illuminated Entry System.
Turn Signal Operation
54 GETTING TO KNOW YOUR VEHICLE

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 ve-
hicles, people, and objects, and most importantly brake
operation to ensure safe operation of the vehicle under
all road conditions. Your complete attention 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.
Disabling And Enabling HSA
This feature can be turned on or turned off. To change the
current setting, proceed as follows:
• If disabling HSA using your instrument cluster display,
refer to “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.
• If disabling HSA using Uconnect Settings, refer to
“Uconnect Settings” in “Multimedia” for further infor-
mation.

SAFETY 217

For vehicles not equipped with an instrument cluster
display, perform the following steps:
1. Center the steering wheel (front wheels pointingstraight 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 four times within 20
seconds. The “ESC Off Indicator Light” should turn on
and turn off two times.
7. Rotate the steering wheel back to center and then an additional slightly more than one-half turn to the right.
8. Turn the ignition to the OFF mode and then back to ON. If the sequence was completed properly, the “ESC Off
Indicator Light” will blink several times to confirm HSA
is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, the TCS may
apply brake pressure to the spinning wheel(s) and/or
reduce engine power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited Differential
(BLD), functions similar to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This
will allow more engine torque to be applied to the wheel
that is not spinning. BLD may remain enabled even if TCS
and ESC are in a reduced mode.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. The ESC
corrects for over/under steering of the vehicle by applying
the brake of the appropriate wheel to assist in counteract-
ing the over/under steer condition. Engine power may also
be reduced to help the vehicle maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match

4L Range (4WD Models)
ESC Full Off
This is the normal operating mode for ESC in 4L range.
Whenever the vehicle is started in 4L range, or the transfer
case (if equipped) is shifted from 4H range or NEUTRAL to
4L range, the ESC system will be in this mode. In 4L range,
ESC and TCS, except for the Brake Limited Differential (BLD)
feature described in the TCS section, are turned off until the
vehicle reaches an approximate speed of 40 mph (64 km/h).
For speeds at or exceeding approximately 40 mph (64 km/h)
the ESC goes intoESC Partial OffWhen the vehicle speed
drops below 35 mph (56 km/h), the ESC system goes back to
ESC Full Off. The ESC is in ESC Full Offat low vehicle
speeds in 4L range so that it will not interfere with off-road
driving, but the ESC function returns to provide the stability
feature at speeds above 40 mph (64 km/h). The “ESC OFF
Indicator Light” will always be illuminated in 4L range when
ESC is in ESC Full Off orESC Partial Off.
NOTE:The “ESC OFF” message will display and an audible
chime will sound when the gear selector is placed in the
PARK position from any other position, and then moved out
of the PARK position. This will occur even if the message was
previously cleared.
WARNING!
With the ESC in ESC Full Offmode, the engine
torque reduction and stability features offered by ESC
and ERM are disabled. In an emergency evasive ma-
neuver, the ESC and ERM systems will not engage to
assist in maintaining stability. The ESC Full Off
mode is intended for off-road use only.
2H Range (4WD Models) Or 2WD Models
ESC On
This is the normal operating mode for ESC in 2H range and
on 2WD vehicles.
ESC Partial Off
When in ESC Partial Off mode, the TCS portion 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.
This mode is intended to be used if the vehicle is in deep
snow, sand, or gravel conditions and more wheel spin than
ESC would normally allow is required to gain traction. To
turn ESC on again, momentarily push the ESC OFF switch.
This will restore the normal ESC Onmode of operation.
222 SAFETY

POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will provide mechanical steering
capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:
•Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
• Upon initial start-up in cold weather, the power steering
pump may make noise for a short amount of time. This
is due to the cold, thick fluid in the steering system. This
noise should be considered normal, and it does not in
any way damage the steering system.
CAUTION!
Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.
Power Steering Fluid Check
Checking the power steering fluid level at a defined service
interval is not required. The fluid should only be checked
if a leak is suspected, abnormal noises are apparent,
and/or the system is not functioning as anticipated. Coor-
dinate inspection efforts through an authorized dealer.
CAUTION!
Do not use chemical flushes in your power steering
system as the chemicals can damage your power steer-
ing components. Such damage is not covered by the
New Vehicle Limited Warranty.

•When installing the Integrated Power Module cover,
it is important to ensure the cover is properly posi-
tioned and fully latched. Failure to do so may allow
water to get into the Integrated Power Module, and
possibly result in an electrical system failure.

CAUTION! (Continued)
•When replacing a blown fuse, it is important to use
only a fuse having the correct amperage rating. The
use of a fuse with a rating other than indicated may
result in a dangerous electrical system overload. If a
properly rated fuse continues to blow, it indicates a
problem in the circuit that must be corrected.
352 IN CASE OF EMERGENCY

If a Non-FFV vehicle is inadvertently fueled with E-85 fuel,
the engine will have some or all of these symptoms:
•Operate in a lean mode.
• OBD II “Malfunction Indicator Light” on.
• Poor engine performance.
• Poor cold start and cold drivability.
• Increased risk for fuel system component corrosion.
CNG And LP Fuel System Modifications
Modifications that allow the engine to run on compressed
natural gas (CNG) or liquid propane (LP) may result in
damage to the engine, emissions, and fuel system compo-
nents. Problems that result from running CNG or LP are
not the responsibility of the manufacturer and may void or
not be covered under the New Vehicle Limited Warranty.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (MMT) is
a manganese-containing metallic additive that is blended
into some gasoline to increase octane. Gasoline blended
with MMT provides no performance advantage beyond
gasoline of the same octane number without MMT. Gaso-
line blended with MMT reduces spark plug life and reduces emissions system performance in some vehicles.
The manufacturer 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
the gasoline contains MMT. MMT is prohibited in Federal
and California reformulated gasoline.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•
The use of leaded gasoline is prohibited by Federal
law. Using leaded gasoline can impair engine perfor-
mance and damage the emissions control system.
• An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your authorized dealer for service assistance.
