27. Electronic Throttle Control (ETC) LightThis light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected, the light will come on
while the engine is running. Cycle the ignition
key when the vehicle has completely stopped and the
shift lever is placed in the NEUTRAL position. The light
should turn off. If the light remains lit with the engine
running, your vehicle will usually be drivable; however,
see an authorized dealer for service as soon as possible. If
the light is flashing when the engine is running, imme-
diate service is required and you may experience reduced
performance, an elevated/rough idle or engine stall and
your vehicle may require towing. The light will come on
when the ignition is first turned to ON/RUN and remain
on briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer. 28. Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON/RUN position and
may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer.

UNDERSTANDING YOUR INSTRUMENT PANEL 167

Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
before the ignition switch can be turned to the full OFF
(key removal) position. The key can only be removed
from the ignition when the ignition is in the full OFF
position, and once removed, the transmission is locked in
PARK.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in PARK
unless the brakes are applied. To shift the transmission
out of PARK, the ignition switch must be turned to the
ON/RUN position (engine running or not), and the
brake pedal (and the lock button on the shift lever) must
be pressed.
Six-Speed Euro Twin Clutch Transmission — If
Equipped
The transmission gear position display (located in the
instrument panel cluster) indicates the transmission gear
range. You must press the brake pedal and the lock
button on the shift lever to move the shift lever out of the
PARK (refer to “Brake/Transmission Shift Interlock Sys-
tem” in this section). To drive, move the shift lever from
PARK or NEUTRAL to the DRIVE position. The
electronically-controlled transmission provides a precise
shift schedule. The transmission electronics are self-
calibrating; therefore, the first few shifts on a new vehicle
may be somewhat abrupt. This is a normal condition, and
precision shifts will develop within a few hundred miles
(kilometers).
218 STARTING AND OPERATING

•When stopped on an incline, always use the brakes to
hold the vehicle in place. On steep inclines, Hill Start
Assist (HSA) will temporarily hold the car in position
when the brake pedal is released. If the accelerator
pedal is not applied after a short time, the car will roll
back. Either reapply the brake (to hold the vehicle) or
press the accelerator to climb the hill.
• Before and after the engine is started, you may hear a
hydraulic pump for a short period of time. This noise
is normal and will not damage the transmission.
• 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
transmission life by reducing excessive shifting and
heat buildup.
• During extremely cold temperatures, the transmission
will not operate if the oil temperature is -22° F (-30° C)
or below. Allow the engine to idle briefly with the
transmission in PARK in order to warm the fluid.
Normal operation will resume once the transmission
temperature has risen to a suitable level.

MESSAGEDESCRIPTION
SHIFT TO NEUTRAL – THEN D or R The transmission has shifted itself into NEUTRAL (due to a fault condition, or overheat due to excessive idling when stopped in
DRIVE with the brakes released), but the shift lever remains in gear. Shift into NEUTRAL and then back into gear for continued driving. If the transmission will not re-engage, see your authorized dealer.
AUTOSTICK NOT AVAILABLE AutoStick® mode is unavailable due to a shift lever fault. See your authorized dealer for diagnosis and service.
AUTOMATIC MODE NOT AVAILABLE The transmission is unable to shift itself automatically, due to a fault condition. Use the AutoStick® mode to shift the transmission manu-ally. See your authorized dealer for diagnosis and service.
REDUCE GEAR CHANGES The transmission pump is overheating. In AutoStick® mode, try to drive in one specific gear as much as possible, avoiding frequent
gear changes. In DRIVE, the transmission will automatically modify its shift schedule to reduce the number of shifts.

Flowing/Rising Water
WARNING!
Do not drive on or across a road or path where water
is flowing and/or rising (as in storm run-off). Flow-
ing water can wear away the road or path’s surface
and cause your vehicle to sink into deeper water.
Furthermore, flowing and/or rising water can carry
your vehicle away swiftly. Failure to follow this
warning may result in injuries that are serious or
fatal to you, your passengers, and others around you.
Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following Cautions
and Warnings before doing so.
WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
• Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stopping
distances. Therefore, after driving through stand-
ing water, drive slowly and lightly press on the
brake pedal several times to dry the brakes.
• Failure to follow these warnings may result in
injuries that are serious or fatal to you, your pas-
sengers, and others around you.

STARTING AND OPERATING 233

CAUTION!
If the Brake Warning Light remains on with the
parking brake released, a brake system malfunction
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 braking
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) thebrakes will still function. However, the effort required to
brake the vehicle will be much greater than that required
with the power system operating.
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 surfaces.
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. Turning
5
STARTING AND OPERATING 237

the ignition Off and On again may reset the ABS if the
fault detected was only momentary.
WARNING!
•Pumping the Anti-Lock Brakes will diminish their
effectiveness and may lead to a collision. Pumping
makes the stopping distance longer. Just press
firmly on your brake pedal when you need to slow
down or stop.
• The Anti-Lock Brake System (ABS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase braking or steering
efficiency beyond that afforded by the condition of
the vehicle brakes and tires or the traction afforded.
• The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
(Continued)
WARNING! (Continued)
•The capabilities of an ABS-equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user’s safety or
the safety of others.
When you are in a severe braking condition involving the
use of the ABS, you will experience some pedal drop as
the vehicle comes to a stop. This is the result of the
system reverting to the base brake system.
Engagement of the ABS may be accompanied by a
pulsing sensation. You may also hear a clicking noise.
These occurrences are normal and indicate that the
system is functioning properly.
238 STARTING AND 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 Con-
trol 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.
Anti-Lock Brake System (ABS)
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lockup and
help avoid skidding on slippery surfaces during braking.
Refer to “Four-Wheel Anti-Lock Brake System” in “Start-
ing and Operating” for further information.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must applycontinuousbrak-
ing pressure during the stopping sequence (do not
“pump” the brakes). Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.
5
STARTING AND OPERATING 239

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 car.
In critical situations (understeering, oversteering, brak-
ing with different grip conditions), through the DST
function the ESC system controls the steering to imple-
ment 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 car control feeling.
NOTE:The DST is a driving aid system and does not
replace the driver’s actions while driving the car.
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 understeer condition.
• Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
242 STARTING AND OPERATING

result in unsatisfactory engine coolant (antifreeze)
performance, poor gas mileage, and increased emis-
sions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting or
riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. Riding the brakes may also
reduce braking capacity in an emergency.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the “Brake Warning Light” is on.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the
fluid level up to the requirements described on the brake
fluid reservoir. Fluid level can be expected to fall as the
brake pads wear. The brake fluid level should be checked
when the pads are replaced. However, low fluid level
may be caused by a leak and a checkup may be needed.
