HSA (Hill Start Assist) — Manual Transmission
Only
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 their foot off of 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
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 7% grade or greater hill.
•Gear selection matches vehicle uphill direction (i.e.,
vehicle facing uphill is in forward gear; vehicle back-
ing uphill is in REVERSE gear).
WARNING!
There may be situations on minor hills (i.e., less than
8%), 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 on or off the HSA system, it can be
done using the Customer Programmable Features in the
Electronic Vehicle Information Center (EVIC). Refer to
“Electronic Vehicle Information Center (EVIC)” in Sec-
tion 4 of this manual.

STARTING AND OPERATING 283

For vehicles not equipped with the EVIC, perform the
following steps:
NOTE:You must complete Steps 1 through 8 within
90 seconds.
1. Center the steering wheel (front wheels pointing
straight forward).
2. Shift the transmission into NEUTRAL.
3. Apply the parking brake.
4. Start the engine.
5. Release the clutch pedal.
6. Rotate the steering wheel one-half turn to the left.
7. Press the “ESP OFF” switch (located in the lower
switch bank below the climate controls) four times within
20 seconds. The “ESP/TCS Indicator Light” should turn
on and turn off two times.8. Rotate the steering wheel back to center and then an
additional half-turn to the right.
9. Turn the ignition switch to the OFF position and then
back to the ON position. If the sequence was completed
properly, the “ESP/TCS Indicator Light” will blink sev-
eral times to confirm HSA is disabled.
10. Repeat these steps if you want to return this feature
to it’s previous setting.
ESP (Electronic Stability Program) — If Equipped
This system enhances directional control and stability of
the vehicle under various driving conditions. The ESP
corrects for oversteering and understeering the vehicle
by applying the brake of the appropriate wheel. Engine
power may also be reduced to assist in counteracting the
condition of oversteer or understeer and help the vehicle
maintain the desired path.
284 STARTING AND OPERATING

The ESP uses sensors in the vehicle to determine the path
that the driver intends to steer the vehicle and compares
it to the actual path of the vehicle. When the actual path
does not match the intended path, the ESP applies the
brake of the appropriate wheel to assist in counteracting
the condition of oversteer or understeer.
•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.
The “ESP/TCS Indicator Light” located in the
instrument cluster, starts to flash as soon as the
tires lose traction and the ESP system becomes
active. The “ESP/TCS Indicator Light” also
flashes when TCS is active. If the “ESP/TCS Indicator
Light” begins to flash during acceleration, ease up on theaccelerator and apply as little throttle as possible. Be sure
to adapt your speed and driving to the prevailing road
conditions.
WARNING!
The ESP cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions. The
ESP cannot prevent accidents, including those result-
ing from excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. Only a safe, at-
tentive, and skillful driver can prevent accidents. The
capabilities of an ESP-equipped vehicle must never
be exploited in a reckless or dangerous manner that
could jeopardize the user’s safety or the safety of
others.

STARTING AND OPERATING 285

CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes, and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
•Do not connect trailer brakes to your vehicle’s
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have an
accident.
(Continued)
WARNING! (Continued)
•Towing any trailer will increase your stopping
distance. When towing, you should allow for ad-
ditional space between your vehicle and the ve-
hicle in front of you. Failure to do so could result
in an accident.
Towing Requirements — Trailer Lights and Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-
pin wiring harness. Use a factory approved trailer har-
ness and connector.
NOTE:Do not cut or splice wiring into the vehicles
wiring harness.5

364 MAINTAINING YOUR VEHICLE

WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. 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. You would not have your full
braking capacity in an emergency.
Master Cylinder - Brake Fluid Level Check
Check the fluid level in the master cylinder immediately
if the brake system warning light indicates system fail-
ure.
Check the fluid level in the master cylinder when per-
forming underhood services.
Clean the top of the master cylinder area before removing
the cap. Add fluid to bring the level up to the “MAX”
mark on the side of the master cylinder reservoir.Overfilling of fluid is not recommended because it may
cause leaking in the system.
Add enough fluid to bring the level up to the require-
ments described on the brake fluid reservoir. With disc
brakes, fluid level can be expected to fall as the brake
pads wear. However, low fluid level may be caused by a
leak and a checkup may be needed.
Use only manufacturer’s recommended brake fluid. Re-
fer to “Fluids, Lubricants, and Genuine Parts” in this
section for the correct fluid type.
390 MAINTAINING YOUR VEHICLE

•Check all lights and other electrical items for correct
operation.
At Each Oil Change
•Change the engine oil filter.
•Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
