216 STARTING AND OPERATING

NEUTRAL (N)
Use this range when the vehicle is standing for pro-
longed periods with the engine running. The engine
may be started in this range. Apply the parking brake
and shift the transmission into PARK if you must leave
the vehicle.
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 traf-
fic 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. Refer to
“Recreational Towing” in “Starting And Operating”
and “Towing A Disabled Vehicle” in “What To Do
In Emergencies” for further information.DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through all forward gears. The
DRIVE position provides optimum driving characteris-
tics under all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading con-
ditions, in hilly terrain, or traveling into strong head
winds), use the AutoStick shift control (refer to
AutoStick in this section for further information) to
select a lower gear. Under these conditions, using a
lower gear will improve performance and extend trans-
mission life by reducing excessive shifting and heat
buildup.
If the transmission temperature exceeds normal operat-
ing limits, the transmission controller will expand the
range of torque converter clutch engagement. This is
done to prevent transmission damage due to overheat-
ing.

STARTING AND OPERATING 225

CAUTION!(Continued)
is indicated. Have the brake system serviced by an
authorized dealer immediately.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems loses
normal capability, the remaining system will still func-
tion. However, there will be some loss of overall brak-
ing effectiveness. You may notice increased pedal travel
during application, greater pedal force required to slow
or stop, and potential activation of the “Brake System
Warning Light”.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off), the
brakes will still function. However, the effort required
to brake the vehicle will be much greater than that
required with the power system operating.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with a advanced electronic
brake control system that includes the Anti-Lock Brake
System (ABS), Brake Assist System (BAS), Traction
Control System (TCS), Hill Start Assist (HSA), Dynamic Steering Torque (DST), and Electronic Stability Control
(ESC). All systems work together to enhance vehicle
stability and control in various driving conditions and
are commonly referred to as ESC.
Four-Wheel Anti-Lock Brake System (ABS)
The Four-Wheel ABS is designed to aid the driver in
maintaining vehicle control under adverse braking con-
ditions. The system operates with a separate computer
to modulate hydraulic pressure, to prevent wheel
lock-up and to help avoid skidding on slippery sur-
faces.
The system’s pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
The ABS includes an amber ABS Warning Light. When
the light is illuminated, the ABS is not functioning. The
system reverts to standard non-anti-lock brakes. Turn-
ing the ignition Off and On again may reset the ABS if
the fault detected was only momentary.
232 STARTING AND OPERATING

WARNING!(Continued)
vehicle, nor can it increase the traction afforded
by prevailing road conditions.
• The BAS cannot prevent collisions, including
those resulting from excessive speed in turns,
driving on very slippery surfaces, or hydroplan-
ing.
• The capabilities of a BAS-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user ’s safety
or the safety of others.
Traction Control System (TCS)
The Traction Control System (TCS) monitors the
amount of wheel spin of each of the driven wheels. If
wheel spin is detected, brake pressure is applied to the
slipping wheel(s) and engine power is reduced to
provide enhanced acceleration and stability. A feature of
the TCS system, Brake Limited Differential (BLD), func-
tions 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. This feature remains active even if
TCS and ESC are in the Partial Off mode or Full Off
mode. Refer to “Electronic Stability Control (ESC)” in
this section for further information.
Hill Start Assist (HSA)
The HSA system is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will
maintain the level of brake pressure the driver applied
for a short period of time after the driver takes his foot
off the brake pedal. If the driver does not apply the
throttle during this short period of time, the system will
release brake pressure and the vehicle will roll down
the hill. The system will release brake pressure in
proportion to the amount of throttle applied as the
vehicle starts to move in the intended direction of
travel.
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
•
Vehicle must be stopped.
• Vehicle must be on a 5% grade or greater hill.
234 STARTING AND OPERATING

•Gear selection matches vehicle uphill direction (i.e.,
vehicle in NEUTRAL (manual transmission), vehicle
facing uphill is in forward gear; vehicle backing
uphill is in REVERSE gear).
WARNING!
There may be situations on minor hills with a
loaded vehicle, or while pulling a trailer, when the
system will not activate and slight rolling may
occur. This could cause a collision with another
vehicle or object. Always remember the driver is
responsible for braking the vehicle.
Disabling/Enabling HSA
If you wish to turn the HSA system on or off, it can be
done using the Customer Programmable Features in the
Uconnect Settings. Refer to “Uconnect Settings” in for
further information.
Dynamic Steering Torque (DST)
The DST function uses the integration of the ESC
system with the electric power steering to increase the
safety level of the whole vehicle. In critical situations (braking with different grip condi-
tions), through the DST function the ESC system con-
trols the steering to implement an additional torque
contribution on the steering wheel, to suggest the most
correct manoeuvre to the driver.
The coordinated action of brakes and steering increases
the safety and vehicle control feeling.
NOTE:
The DST is a driving aid system and does not
replace the driver’s actions while driving the vehicle.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for oversteering or understeering of the vehicle by
applying the brake of the appropriate wheel to assist in
counteracting the oversteering or understeering condi-
tion. 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 the
intended path, ESC applies the brake of the appropriate
wheel to assist in counteracting the oversteer or under-
steer condition.

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the pointer rises to the H (red) mark,
the instrument cluster will sound a chime. When
safe, pull over and stop the vehicle with the engine
at idle. Turn off the air conditioning and wait until
the pointer drops back into the normal range. If the
pointer remains on the H (red) mark for more than
a minute, turn the engine off immediately and call
for service.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle the lug nuts/bolts should be torqued using a
properly calibrated torque wrench.

WHAT TO DO IN EMERGENCIES 275

Inspect the wheel mounting surface prior to mounting
the tire and remove any corrosion or loose particles.
Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice.After 25 miles (40 km) check the lug nut/bolt torque to
be sure that all the lug nuts/bolts are properly seated
against the wheel.
WARNING!
To avoid the risk of forcing the vehicle off the jack,
do not tighten the lug nuts fully until the vehicle
has been lowered. Failure to follow this warning
may result in personal injury.

8. Install the wheel bolts with the threaded end of thewheel bolt toward the wheel. Lightly tighten the
wheel bolts.
WARNING!
•To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts fully until the
vehicle has been lowered. Failure to follow this
warning may result in personal injury.
• To avoid possible personal injury, handle the
wheel covers with care to avoid contact with any
sharp edges.
9. Lower the vehicle to the ground by turning the jack handle counterclockwise.
10. Finish tightening the wheel bolts. Push down on the wrench while at the end of the handle for increased
leverage. Tighten the wheel bolts in a star pattern
until each wheel bolt has been tightened twice.
Refer to Torque Specifications in this section for
proper lug nut torque. If in doubt about the correct
tightness, have them checked with a torque wrench
by your authorized dealer or at a service station. 11. Stow the jack, tools and flat tire.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the
vehicle. Always stow the jack parts and the spare
tire in the places provided. Have the deflated (flat)
tire repaired or replaced immediately.
Spare Tire Stowage
Rotate the jack wrench tool on the winch drive nut
clockwise (the flat tire must not be connected to the
winch) until effort becomes heavy and an audible click
is heard indicating the winch is properly stowed.
Cover the flat tire with the Emergency Spare Tire Bag
and stow the flat tire into the trunk.
CAUTION!
The winch mechanism is designed for use with the
jack wrench extension tool only. Use of air wrench
or power tool may damage the winch.

WHAT TO DO IN EMERGENCIES 285

Automatic Transmission
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. Refer to “Fluids, Lubricants, And Genuine Parts”
in this section for fluid specifications. It is important to
maintain the transmission fluid at the correct level
using the recommended fluid. No chemical flushes
should be used in any transmission; only the approved
lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufac-
turer ’s recommended fluid may cause deterioration
in transmission shift quality and/or torque con-
verter shudder. Refer to “Fluids, Lubricants, And
Genuine Parts” in this section for fluid specifica-
tions.
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. The only exception to this
policy is the use of special dyes for diagnosing fluid
leaks. Avoid using transmission sealers as they may
adversely affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission com-
ponents. Such damage is not covered by the New
Vehicle Limited Warranty.
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. Your authorized dealer
can check your transmission fluid level using special
service tools. If you notice fluid leakage or transmission
malfunction, visit your authorized dealer immediately
to have the transmission fluid level checked. Operating
