222 STARTING AND OPERATING

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) 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 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.
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

STARTING AND OPERATING 257

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 en-
hanced acceleration and stability. A feature of the TCS
system, Brake Limited Differential (BLD), functions simi-
lar 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 “Elec-
tronic 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.
260 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 brak-
ing 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
Electronic Vehicle Information Center (EVIC). Refer to
“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion.
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.

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.
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.
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 313

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.
TIRE SERVICE KIT — IF EQUIPPED
Small punctures up to¼” (6 mm) in the tire tread can be
sealed with Tire Service Kit. Foreign objects (e.g., screws
or nails) should not be removed from the tire. Tire Service
Kit can be used in outside temperatures down to approxi-
mately -4°F (-20°C).Torque Patterns
