seat position is greater than or equal to
2.7 inches (67.7 mm) forward of the rear
stop. The seat will return to its previously set
position when you place the vehicle’s ignition
in the ACC or RUN position.
The Easy Entry/Easy Exit feature is disabled
when the driver seat position is less than
0.9 of an inch (22.7 mm) forward of the rear
stop. At this position, there is no benefit to
the driver by moving the seat for Easy Exit or
Easy Entry.
Each stored memory setting will have an
associated Easy Entry and Easy Exit position.
NOTE:
The Easy Entry/Exit feature is not enabled when
the vehicle is delivered from the factory. The
Easy Entry/Exit feature is enabled (or later
disabled) through the programmable features
in the Uconnect system. Refer to “Uconnect
Settings” in “Multimedia”.
HEATED SEATS — IF EQUIPPED
On some models, the front and rear seats may
be equipped with heaters located in the seat
cushions and seat backs.
Front Heated Seats
The front heated seat control buttons are
located within the climate or controls screen of
the touchscreen.
You can choose from HI, LO, or OFF heat

If the HI-level setting is selected, the system will
automatically switch to LO-level after
approximately 60 minutes of continuous
operation. At that time, the display will change
from HI to LO, indicating the change. The
LO-level setting will turn off automatically after
approximately 45 minutes.
NOTE:
Once a heat setting is selected, heat will be
felt within two to five minutes.
The engine must be running for the heated
seats to operate.
WARNING!
Persons who are unable to feel pain to the
skin because of advanced age, chronic
illness, diabetes, spinal cord injury, medica -
tion, alcohol use, exhaustion or other phys -
ical condition must exercise care when
using the seat heater. It may cause burns
even at low temperatures, especially if
used for long periods of time.
Do not place anything on the seat or seat -
back that insulates against heat, such as a
blanket or cushion. This may cause the seat
heater to overheat. Sitting in a seat that has
been overheated could cause serious
burns due to the increased surface
temperature of the seat.

Manual Operation Override
This system offers a full complement of manual
override features. The AUTO symbol in the front
ATC display will be turned off when the system
is being used in the manual mode.
OPERATING TIPS
NOTE:
Refer to the chart at the end of this section for
suggested control settings for various weather
conditions.
Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to provide
proper corrosion protection and to protect
against engine overheating. OAT coolant
(conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and
defroster performance, make sure the engine
cooling system is functioning properly and the
proper amount, type, and concentration of
coolant is used. Use of the Air Recirculation mode during Winter months is not
recommended, because it may cause window
fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more,
run the air conditioning system at idle for about
five minutes, in fresh air with the blower setting
on high. This will ensure adequate system
lubrication to minimize the possibility of
compressor damage when the system is started
again.
Window Fogging
Vehicle windows tend to fog on the inside in
mild, rainy, and/or humid weather. To clear the
windows, select Defrost or Mix mode and
increase the front blower speed. Do not use the
Recirculation mode without A/C for long
periods, as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in
front of the windshield, is free of obstructions,
such as leaves. Leaves collected in the air
intake may reduce airflow, and if they enter the
plenum, they could plug the water drains. In
Winter months, make sure the air intake is clear
of ice, slush, and snow.
CAUTION!
Failure to follow these cautions can cause
damage to the heating elements:
Use care when washing the inside of the
rear window. Do not use abrasive window
cleaners on the interior surface of the
window. Use a soft cloth and a mild
washing solution, wiping parallel to the
heating elements. Labels can be peeled off
after soaking with warm water.
Do not use scrapers, sharp instruments, or
abrasive window cleaners on the interior
surface of the window.
Keep all objects a safe distance from the
window.

The warning / indicator Lights will briefly illumi -
nate for a bulb check when the ignition is first
cycled.
INSTRUMENT CLUSTER DISPLAY
Your vehicle is equipped with an instrument
cluster display, which offers useful information
to the driver. With the ignition in the OFF mode,
opening/closing of a door will activate the
display for viewing, and display the total miles,
or kilometers, in the odometer. Your instrument
cluster display is designed to display important
information about your vehicle’s systems and
features. Using a driver interactive display
located on the instrument panel, your
instrument cluster display can show you how systems are working and give you warnings
when they are not. The steering wheel mounted
controls allow you to scroll through the main
menus and submenus. You can access the
specific information you want and make
selections and adjustments.
LOCATION AND CONTROLS
The instrument cluster display features an
interactive display which is located in the
instrument cluster.
This system conveniently allows the driver to
select a variety of useful information by pushing
the arrow buttons located on the left side of the
steering wheel. The instrument cluster display
menu items consist of the following:
Speedometer
Vehicle Info
Driver Assist — If Equipped
Fuel Economy
Trip
Audio
Messages
Screen Setup
WARNING!
A hot engine cooling system is dangerous.
You or others could be badly burned by steam
or boiling coolant. You may want to call an
authorized dealer for service if your vehicle
overheats.
CAUTION!
Driving with a hot engine cooling system
could damage your vehicle. If the
temperature gauge reads “H,” pull over and
stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops

Electronic Stability Control (ESC) OFF
Warning Light — If Equipped
This warning light indicates the
Electronic Stability Control (ESC) is
off.
Each time the ignition is turned to ON/RUN or
ACC/ON/RUN, the ESC system will be on, even
if it was turned off previously.
Low Washer Fluid Warning Light — If
Equipped
This warning light will illuminate when
the windshield washer fluid is low.
Refer to “Engine Compartment” in “Servicing
And Maintenance” for further information.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a
message is displayed to indicate that
the tire pressure is lower than the
recommended value and/or that slow
pressure loss is occurring. In these cases,
optimal tire duration and fuel consumption may
not be guaranteed. Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitoring
System (TPMS) that illuminates a low tire
pressure warning light when one or more of your
tires is significantly under-inflated. Accordingly,
when the low tire pressure warning light illuminates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure warning light.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure warning light. When the system
detects a malfunction, the warning light will
flash for approximately one minute and then
remain continuously illuminated. This sequence
will continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the
malfunction indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
CAUTION!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop
the vehicle, avoiding sharp braking and
steering. If a tire puncture occurs, repair
immediately using the dedicated tire repair
kit and contact an authorized dealer as soon
as possible.

on current vehicle speed and gear). Lack of
accelerator pedal activity will cause the
transmission to revert to automatic opera -
tion.
If AutoStick is engaged while the transmis -
sion gear selector is in the SPORT position,
manual gear selection will be maintained
until the gear selector is returned to DRIVE, or
as described below. The transmission will not
upshift automatically at redline in this mode,
nor will downshifts be obtained if the acceler -
ator pedal is pressed to the floor.
In either DRIVE or SPORT mode, the transmis -
sion will automatically downshift as the
vehicle slows (to prevent engine lugging) and
will display the current gear.
The transmission will automatically down -
shift to FIRST gear when coming to a stop.
After a stop, the driver should manually
upshift (+) the transmission as the vehicle is
accelerated.
You can start out, from a stop, in FIRST or
SECOND gear. Tapping (+) at a stop will allow
starting in SECOND gear. Starting out in
SECOND gear can be helpful in snowy or icy
conditions.
If a requested downshift would cause the
engine to over-speed, that shift will not occur.
The system will ignore attempts to upshift at
too low of a vehicle speed.
Holding the (-) paddle depressed will down -
shift the transmission to the lowest gear
possible at the current speed.
Transmission shifting will be more noticeable
when AutoStick is enabled.
The system may revert to automatic shift
mode if a fault or overheat condition is
detected.
To disengage AutoStick mode, press and hold
the (+) shift paddle until "D" or "S" is once again
indicated in the instrument cluster. Shifting out
of SPORT mode will also disable AutoStick. You
can shift in or out of AutoStick mode at any time
without taking your foot off the accelerator
pedal.
SPORT MODE — IF EQUIPPED

SPORT Mode Button

If your vehicle is equipped with SPORT mode,
this mode is a configuration set up for typical
enthusiast driving. The engine, transmission
and steering systems are all set to their SPORT
settings. SPORT Mode will provide improved
throttle response and modified shifting for an
enhanced driving experience, as well the
greatest amount of steering feel. This mode
may be activated and deactivated by pushing
the SPORT button on the instrument panel
switch bank.
WARNING!

Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.

20_LX_OM_EN_USC_t.book Page 159

198STARTING AND OPERATING
AutoStick — If Equipped
When using the AutoStick shift control, select
the highest gear that allows for adequate
performance and avoids frequent down -
shifts. For example, choose “5” if the desired
speed can be maintained. Choose “4” or “3”
if needed to maintain the desired speed.
To prevent excess heat generation, avoid
continuous driving at high RPM. Reduce
vehicle speed as necessary to avoid
extended driving at high RPM. Return to a
higher gear or vehicle speed when grade and
road conditions allow.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
In city traffic — while stopped, place the trans -
mission in NEUTRAL, but do not increase
engine idle speed.
Highway Driving
Reduce speed.
Temporarily turn off air conditioning.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Recreational towing (with all four wheels on the
ground, or using a tow dolly) is NOT ALLOWED.
The only acceptable method for towing this
vehicle (behind another vehicle) is on a vehicle
trailer with all four wheels OFF the ground.
DRIVING TIPS
DRIVING ON SLIPPERY SURFACES
Information in this section will aid in safe
controlled launches in adverse conditions.
Acceleration
Rapid acceleration on snow covered, wet, or
other slippery surfaces may cause the driving
wheels to pull erratically to the right or left. This
phenomenon occurs when there is a difference
in the surface traction under the rear (driving)
wheels.
CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe transmission
and/or transfer case damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
WARNING!
Rapid acceleration on slippery surfaces is
dangerous. Unequal traction can cause
sudden pulling of the front wheels. You could
lose control of the vehicle and possibly have a
collision. Accelerate slowly and carefully
whenever there is likely to be poor traction
(ice, snow, wet, mud, loose sand, etc.).

20_LX_OM_EN_USC_t.book Page 198

IN CASE OF EMERGENCY225
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL, but do not increase the
engine idle speed while preventing vehicle
motion with the brakes.
NOTE:
There are steps that you can take to slow down
an impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off.
The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the
heater core to act as a supplement to the
radiator and aids in removing heat from the
engine cooling system.
MANUAL PARK RELEASE
To move the vehicle in cases where the
transmission will not shift out of PARK (such as
a depleted battery), a Manual Park Release is
available.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming
from under the hood, do not open the hood
until the radiator has had time to cool. Never
try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the
vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on HOT (H), and you hear continuous
chimes, turn the engine off immediately and
call for service.
WARNING!
Always secure your vehicle by fully applying
the parking brake before activating the
Manual Park Release. In addition, you should
be seated in the driver's seat with your foot
firmly on the brake pedal when activating the
Manual Park Release. Activating the Manual
Park Release will allow your vehicle to roll
away if it is not secured by the parking brake,
or by proper connection to a tow vehicle.
Activating the Manual Park Release on an
unsecured vehicle could lead to serious injury
or death for those in or around the vehicle.
