rized dealer to service your cabin air filter,
and to have it replaced when needed.
WINDOWS
Power Window Controls
The window controls on the driver's door
control all the door windows.
There are single window controls on each
passenger door trim panel, which operate the
passenger door windows. The window con-
trols will operate only when the ignition is in
the ACC or ON/RUN position.If equipped, the key fob may also be used to
raise or lower vehicle windows while the igni-
tion is in the “OFF” position. Refer to “Keys”
in “Getting To Know Your Vehicle” for further
information.
WARNING!
Never leave children unattended in a ve-
hicle, and do not let children play with
power windows. Do not leave the key fob in
or near the vehicle, or in a location acces-
sible to children, and do not leave the
ignition of a vehicle equipped with Keyless
Enter-N-Go in the ACC or ON/RUN mode.
Occupants, particularly unattended chil-
dren, can become entrapped by the win-
dows while operating the power window
switches. Such entrapment may result in
serious injury or death.

• The power liftgate will not operate in tem-
peratures below −22°F (−30°C) or tem-
peratures above 150° F (65° C). Be sure to
remove any buildup of snow or ice from the
liftgate before pushing any of the power
liftgate switches.
• If anything obstructs the power liftgate
while it is closing or opening, the liftgate
will automatically reverse to the closed or
open position, provided it meets sufficient
resistance.
• There are also pinch sensors attached to
the side of the liftgate. Light pressure any-
where along these strips will cause the
liftgate to return to the open position.
• If the liftgate is not fully open, push the
liftgate button on the key fob twice to
operate the liftgate.
• If the electronic liftgate release is pushed
while the power liftgate is closing, the lift-
gate will reverse to the full open position.• If the electronic liftgate release is pushed
while the power liftgate is opening, the
liftgate motor will disengage to allow
manual operation.
• If the power liftgate encounters multiple
obstructions within the same cycle, the
system will automatically stop and the lift-
gate must be opened or closed manually.
WARNING!
• Driving with the liftgate open can allow
poisonous exhaust gases into your ve-
hicle. You and your passengers could be
injured by these fumes. Keep the liftgate
closed when you are operating the
vehicle.
• If you are required to drive with the
liftgate open, make sure that all win-
dows are closed, and the climate control
blower switch is set at high speed. Do
not use the recirculation mode.

For vehicles not equipped with an instrument
cluster display, perform 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 con-
trol 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 Indica-
tor Light” will blink several times to con-
firm HSA is disabled.
9. Repeat these steps if you want to return
this feature to its previous setting.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 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 roll-
ing down an incline while resuming ac-
celeration, manually activate the trailer
brake or apply more vehicle brake pres-
sure prior to releasing the brake pedal.
• HSA is not a parking brake. Always apply
the parking brake fully when exiting your
vehicle. Also, be certain to place the
transmission in PARK.
• Failure to follow these warnings can re-
sult in a collision or serious personal
injury.
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 re-
duce engine power to provide enhanced ac-
celeration and stability. A feature of the TCS,
Brake Limited Differential (BLD), functions
similar to a limited slip differential and con-
trols 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 power to be applied to the wheel
that is not spinning. BLD may remain en-
abled 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. ESC corrects for oversteering or
understeering of the vehicle by applying the
brake of the appropriate wheel(s) to assist in
counteracting the oversteer or understeer
condition. Engine power may also be reduced
to help the vehicle maintain the desired path.

Hazard Warning flasher. When the
switch is activated, all directional
turn signals will flash on and off to
warn oncoming traffic of an emergency. Push
the switch a second time to turn off the
Hazard Warning flashers.This is an emergency warning system and it
should not be used when the vehicle is in
motion. Use it when your vehicle is disabled
and it is creating a safety hazard for other
motorists.
When you must leave the vehicle to seek
assistance, the Hazard Warning flashers will
continue to operate even though the ignition
is placed in the OFF position.
NOTE:
With extended use, the Hazard Warning
flashers may discharge the battery.

the cover is properly positioned and fully
latched. Failure to do so may allow water
to get into the power distribution center
and possibly result in an electrical sys-
tem failure.
• When replacing a blown fuse, it is impor-
tant to use only a fuse having the correct
amperage rating. The use of a fuse with
CAUTION!
a rating other than indicated may result
in a dangerous electrical system over-
load. If a properly rated fuse continues
to blow, it indicates a problem in the
circuit that must be corrected.
