GETTING TO KNOW YOUR VEHICLE63
NOTE:If the vehicle is moving less than 10 mph (16 km/h), delay
times will be doubled.
Windshield Washer Operation
To use the washer, pull the lever rearward toward you and
hold. If the lever is pulled while on the intermittent setting,
the wipers will turn on and operate for several wipe cycles
after the lever is released, and then resume the
intermittent interval previously selected. If the lever is
pulled while the wipers are in the off position, the wipers
will operate several cycles, then turn off.
NOTE:
As a protective measure, the pump will stop if the
switch is held for more than 20 seconds. Once the
switch is released the pump will resume normal
operation.
 If the front window washer feature is activated, all of
the front cameras (if equipped) on the vehicle will be
washed as well.
Mist
Use the Mist feature when weather conditions make
occasional usage of the wipers necessary. Push the lever
upward to the MIST position and release for a single
wiping cycle.
NOTE:The Mist feature does not activate the washer pump;
therefore, no washer fluid will be sprayed on the wind -
shield. The washer function must be used in order to spray
the windshield with washer fluid.
For information on wiper care and replacement, see
Úpage 324.
RAIN SENSING WIPERS — IF EQUIPPED
This feature senses rain or snowfall on the windshield and
automatically activates the wipers. Rotate the end of the
windshield wiper lever to one of the four detent positions
to activate this feature.
The sensitivity of the system is adjustable from the
windshield wiper lever. Wiper sensitivity position 1 is the
least sensitive, and wiper sensitivity position 4 is the most
sensitive.
NOTE:
 The Rain Sensing feature will not operate when the
wiper switch is in the low or high position.
 The Rain Sensing feature may not function properly
when ice or dried saltwater is present on the wind -
shield.
 Use of products containing wax or silicone may reduce
rain sensor performance. 
The Rain Sensing feature can be turned on and off
through the Uconnect system
Úpage 197.
The Rain Sensing system has protective features for the
wiper blades and arms. It will not operate under the
following conditions:
 Low Temperature Wipe Inhibit — The Rain Sensing
feature will not operate when the ignition is first placed
in the ON position, when the vehicle is stationary and
the outside temperature is below 32°F (0°C), unless
the wiper control on the windshield wiper lever is
moved, the vehicle speed becomes greater than 3 mph
(5 km/h) or the outside temperature rises above
freezing.
 Neutral Wipe Inhibit — The Rain Sensing feature will not
operate when the ignition is ON, when the transmission
gear selector is in the NEUTRAL position and the
vehicle speed is less than 3 mph (5 km/h), unless the
wiper control on the windshield wiper lever is moved,
the vehicle speed is greater than 3 mph (5 km/h) or
the gear selector is moved out of the NEUTRAL posi -
tion.
 Remote Start Mode Inhibit — On vehicles equipped with
the Remote Start system, Rain Sensing wipers are not
operational when the vehicle is in the Remote Start
mode. Once the operator is in the vehicle and has
placed the ignition switch in the ON/RUN position, rain
sensing wiper operation can resume, if it has been
selected, and no other inhibit conditions
(mentioned previously) exist.
WARNING!
Sudden loss of visibility through the windshield could
lead to a collision. You might not see other vehicles or
other obstacles. To avoid sudden icing of the windshield
during freezing weather, warm the windshield with the
defroster before and during windshield washer use.

112GETTING TO KNOW YOUR INSTRUMENT PANEL
Air Suspension Fault Warning Light
This light will illuminate when there is a fault
detected in the air suspension system.
Drowsy Driver Detected System Fault
Warning Light — If Equipped
This warning light will illuminate when the
Drowsy Driver Detected (DDD) system is not
operating correctly and requires service.
Please see an authorized dealer.
Electric Park Brake Warning Light
This warning light will illuminate to indicate the
Electric Park Brake is not functioning properly
and service is required. Contact an authorized
dealer.
Electronic Stability Control (ESC) Active
Warning Light
This warning light will indicate when the ESC
system is Active. The ESC Indicator Light in the
instrument cluster will come on when the
ignition is placed in the ON/RUN position, and
when ESC is activated. It should go out with the engine
running. If the ESC Indicator Light comes on continuously
with the engine running, a malfunction has been detected
in the ESC system. If this warning light remains on after
several ignition cycles, and the vehicle has been driven
several miles (kilometers) at speeds greater than 30 mph
(48 km/h), see an authorized dealer as soon as possible
to have the problem diagnosed and corrected. 
The ESC OFF Indicator Light and the ESC Indicator Light
come on momentarily each time the ignition is placed
in the ON/RUN position.
 The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive.
 This light will come on when the vehicle is in an ESC
event.
Electronic Stability Control (ESC) OFF
Warning Light
This warning light indicates the ESC is off.
Each time the ignition is turned to ON/RUN, the
ESC system will be on, even if it was turned off
previously.
Service Active Lane Management
Warning Light — If Equipped
This warning light will illuminate when the
Active Lane Management system is not
operating and requires service. Please see an
authorized dealer.
Active Lane Management Warning
Light — If Equipped
The Active Lane Management Warning Light
will be solid yellow when the vehicle is
approaching a lane marker. The warning light
will flash when the vehicle is crossing the lane
marker
Úpage 167.
Low Fuel Warning Light
When the fuel level reaches approximately
2 gal (7.5 L), this light will turn on and a chime
will sound. The light will remain on until fuel is
added.
Fuel Cutoff Failure Light — If Equipped
This light will illuminate if there is a fuel cutoff
failure. If this light illuminates, take it to an
authorized dealer and have them inspect it.
Low Washer Fluid Warning Light
This warning light will illuminate when the
windshield washer fluid is low Úpage 317.
Engine Check/Malfunction Indicator
Warning Light (MIL)
The Engine Check/Malfunction Indicator Light
(MIL) is a part of an Onboard Diagnostic System
called OBD II that monitors engine and
automatic transmission control systems.
This warning light will illuminate when the ignition is in the
ON/RUN position before engine start. If the bulb does not
come on when turning the ignition switch from OFF to
ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap,
poor quality fuel, etc., may illuminate the light after engine
start. The vehicle should be serviced if the light stays on
through several typical driving styles. In most situations,
the vehicle will drive normally and will not require towing.

23_WS_OM_EN_USC_t.book Page 112

128STARTING AND OPERATING
NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking brake
and shift the transmission into PARK (P) if you must exit
the vehicle.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission
automatically upshifts through all forward gears. When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong head
winds, or while towing a heavy trailer), use the Electronic
Range Select (ERS) shift control to select a lower gear
Úpage 129. Under these conditions, using a lower gear
will improve performance and extend transmission life by
reducing excessive shifting and heat build-up.
During cold temperatures, transmission operation may be
modified depending on engine and transmission
temperature as well as vehicle speed. This feature
improves warm-up time of the engine and transmission to
achieve maximum efficiency. Engagement of the torque
converter clutch is inhibited until the transmission fluid is
warm. Normal operation will resume once the
transmission temperature has risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
mode is activated. In this mode, the transmission may
operate only in certain gears, or may not shift at all.
Vehicle performance may be severely degraded and the
engine may stall. In some situations, the transmission may
not re-engage if the engine is turned off and restarted. The
Malfunction Indicator Light (MIL) may be illuminated. A
message in the instrument cluster will inform the driver of
the more serious conditions, and indicate what actions
may be necessary. In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
NOTE:In cases where the instrument cluster message indicates
the transmission may not re-engage after engine
shutdown, perform this procedure only in a desired
location (preferably, at an authorized dealer).

1. Stop the vehicle.

2. Shift the transmission into PARK (P), if possible.
If not, shift the transmission to NEUTRAL (N).
3. Push and hold the ignition switch until the engine turns off.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to
normal operation.
NOTE:Even if the transmission can be reset, we recommend that
you visit an authorized dealer at your earliest possible
convenience. An authorized dealer has diagnostic
equipment to assess the condition of your transmission.
If the transmission cannot be reset, authorized dealer
service is required.
WARNING!
Do not coast in NEUTRAL and never turn off the ignition
to coast down a hill. These are unsafe practices that
limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage.
For Recreational Towing see
Úpage 190.
For Towing A Disabled Vehicle see
Úpage 306.

23_WS_OM_EN_USC_t.book Page 128

326SERVICING AND MAINTENANCE
To minimize the possibility of catalytic converter damage:
Do not interrupt the ignition when the transmission is
in gear and the vehicle is in motion.
 Do not try to start the vehicle by pushing or towing the
vehicle.
 Do not idle the engine with any ignition components
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating conditions.
COOLING SYSTEM
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant is dirty, the system
should be drained, flushed, and refilled with fresh Organic
Additive Technology (OAT) coolant (conforming to
MS.90032) by an authorized dealer. Check the front of the
A/C condenser for any accumulation of bugs, leaves, etc.
If dirty, clean by gently spraying water from a garden hose
vertically down the face of the condenser.
Check the engine cooling system hoses for brittle rubber,
cracking, tears, cuts, and tightness of the connection at
the coolant recovery bottle and radiator. Inspect the entire
system for leaks. DO NOT REMOVE THE COOLANT
PRESSURE CAP WHEN THE COOLING SYSTEM IS HOT.
Cooling System — Drain, Flush And Refill
NOTE:Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could lead
to severe internal engine damage. If any coolant is needed
to be added to the system please contact an authorized
dealer.
If the engine coolant (antifreeze) is dirty or contains visible
sediment, have an authorized dealer clean and flush with
Organic Additive Technology (OAT) coolant (conforming to
MS.90032).
For the proper maintenance intervals
Úpage 310.
Selection Of Coolant
Refer to Engine Fluids And Lubricants Úpage 376.
NOTE:
Mixing of engine coolant (antifreeze) other than speci-
fied Organic Additive Technology (OAT) engine coolant,
may result in engine damage and may decrease corro -
sion protection. OAT engine coolant is different and
should not be mixed with Hybrid Organic Additive Tech -
nology (HOAT) engine coolant or any “globally compat -
ible” coolant. If a non-OAT engine coolant is introduced
into the cooling system in an emergency, the cooling
system will need to be drained, flushed, and refilled
with fresh OAT coolant (conforming to MS.90032), by
an authorized dealer as soon as possible.
 Do not use water alone or alcohol-based engine
coolant products. Do not use additional rust inhibitors
or antirust products, as they may not be compatible
with the radiator engine coolant and may plug the radi -
ator.
 This vehicle has not been designed for use with
propylene glycol-based engine coolant. Use of
propylene glycol-based engine coolant is not recom -
mended.
 Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could
lead to severe internal engine damage. If any coolant is
needed to be added to the system please contact an
authorized dealer.
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 open a cooling system pressure cap
when the radiator or coolant bottle is hot.
 Keep hands, tools, clothing, and jewelry away from
the radiator cooling fan when the hood is raised. The
fan starts automatically and may start at any time,
whether the engine is running or not.
 When working near the radiator cooling fan, discon -
nect the fan motor lead or turn the ignition to the OFF
position. The fan is temperature controlled and can
start at any time the ignition is in the ON position.

SERVICING AND MAINTENANCE329
AUTOMATIC TRANSMISSION
Special Additives
The manufacturer strongly recommends against using any
special additives in the transmission. Automatic
Transmission Fluid (ATF) is an engineered product and its
performance may be impaired by supplemental additives.
Therefore, do not add any fluid additives to the
transmission. Avoid using transmission sealers as they
may adversely affect seals.
Fluid Level Check
The fluid level is preset at the factory and does not require
adjustment under normal operating conditions. Routine
fluid level checks are not required; therefore the
transmission has no dipstick. An authorized dealer can
check your transmission fluid level using special service
tools. If you notice fluid leakage or transmission
malfunction, visit an authorized dealer immediately to
have the transmission fluid level checked. Operating the
vehicle with an improper fluid level can cause severe
transmission damage.
Fluid And Filter Changes
Under normal operating conditions, the fluid installed at
the factory will provide satisfactory lubrication for the life
of the vehicle.
Routine fluid and filter changes are not required. However,
change the fluid and filter if the fluid becomes
contaminated (with water, etc.), or if the transmission is
disassembled for any reason.
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer's specified transmission fluid
Úpage 377. It is important to maintain the transmission
fluid at the correct level using the recommended fluid.
NOTE:No chemical flushes should be used in any transmission;
only the approved lubricant should be used.

To avoid contamination from foreign matter or mois -
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master
cylinder reservoir cap secured at all times. Brake
fluid in an open container absorbs moisture from the
air resulting in a lower boiling point. This may cause
it to boil unexpectedly during hard or prolonged
braking, resulting in sudden brake failure. This could
result in a collision.
 Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
 Do not allow petroleum-based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
WARNING!CAUTION!
Do not use chemical flushes in your transmission as the
chemicals can damage your transmission components.
Such damage is not covered by the New Vehicle Limited
Warranty.
CAUTION!
If a transmission fluid leak occurs, visit an authorized
dealer immediately. Severe transmission damage may
occur. An authorized dealer has the proper tools to
adjust the fluid level accurately.
CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may cause
deterioration in transmission shift quality and/or torque
converter shudder.8
