9-36 Driving and Operating
Parking Brake
The parking brake lever is located
to the right of the center console.
To set the parking brake, hold the
brake pedal down. Pull the parking
brake lever up. If the ignition is on,
the brake system warning light will
come on.
To release the parking brake, hold
the brake pedal down. Then push
the release button in as you move
the parking brake lever all the
way down.
Notice:Driving with the parking
brake on can overheat the brake
system and cause premature
wear or damage to brake system
parts. Make sure that the parking
brake is fully released and the
brake warning light is off before
driving.
Brake Assist
This vehicle has a brake assist
feature designed to assist the driver
in stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle.
The stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.
Minor brake pedal pulsation or
pedal movement during this time
is normal and the driver should
continue to apply the brake pedal
as the driving situation dictates.
The brake assist feature will
automatically disengage when
the brake pedal is released or
brake pedal pressure is quickly
decreased.
Ride Control Systems
Traction Control
System (TCS)
The vehicle has a Traction Control
System (TCS) that limits wheel spin.
This is especially useful in slippery
road conditions. The system
operates only if it senses that the
rear wheels are spinning too much
or are beginning to lose traction.
When this happens, the system
works the rear brakes and reduces
engine power (by closing the throttle
and managing engine spark) to limit
wheel spin.
The TRACTION SYSTEM ACTIVE
message displays on the Driver
Information Center (DIC) when TCS
is limiting wheel spin. See Ride
Control System Messages on
page 5‑44. The system may be
heard or felt while it is working, but
this is normal.

Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might want to step on the
accelerator pedal to maintain
the vehicle speed. When going
downhill, you might have to brake or
shift to a lower gear to keep the
vehicle's speed down. When the
brakes are applied the cruise control
is disengaged.
Cruise Control in Sport and
Manual Paddle Shift Gear
Selection
When the vehicle is in S (Sport) and
the manual paddle shift controls are
not being used, cruise control
operates in the same manner as
D (Drive).When the vehicle is in S (Sport) and
the manual paddle shift controls are
being used, cruise control operates
as follows:
.If cruise control is active and a
gear is selected with the manual
paddle shift controls, the vehicle
speed is maintained in the driver
selected gear and will not
automatically up-shift or
down-shift the transmission
while the driver
’s gear selection
is active.
.If driving in hilly terrain, cruise
control may not be able to
maintain vehicle speed if an
up-shift or down-shift is not
selected by the driver. While
driving on hilly terrain and cruise
control is active with a manual
paddle shift gear selection, the
driver must select the proper
gear for the terrain or select
D (Drive) on the gear range
selector for full automatic
transmission operation. Ending Cruise Control
.To disengage cruise control,
step lightly on the brake pedal.
If the vehicle has a manual
transmission, lightly tap the
clutch to end the cruise control
session.
.To turn off the cruise control
system, move the cruise control
switch to
9.
When cruise control is disengaged,
the CRUISE DISENGAGED
message displays on the Driver
Information Center (DIC). See
Cruise Control Messages on
page 5‑38.
Erasing Speed Memory
The cruise control set speed is
erased from memory by moving
the switch to
9or if the ignition is
turned off.

When to Check Power Steering
Fluid
It is not necessary to regularly
check power steering fluid unless
there is a leak suspected in the
system or an unusual noise is
heard. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.
How to Check Power Steering
Fluid
Notice:Extremely small amounts
of contamination can cause
steering system damage and
cause it to not work properly.
Do not allow contaminants to
contact the fluid side of the
reservoir cap/dipstick or to enter
the reservoir.
To check the power steering fluid:
1. Turn the ignition off and let the engine compartment cool down.
2. Wipe the cap and the top of the reservoir clean. 3. Unscrew the cap and wipe the
dipstick with a clean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the fluid level on the dipstick.
There are markings on both
sides of the dipstick.
The level should be at the FULL
COLD mark. If necessary, add only
enough fluid to bring the level up to
the mark.
When the engine compartment
is hot, the level should be at
the HOT mark. When the engine compartment is
cool, the level should be at the
FULL COLD mark.
What to Use
To determine what kind of fluid to
use, see
Recommended Fluids
and Lubricants on page 11‑12.
Always use the proper fluid.
Notice: Use of the incorrect fluid
may damage the vehicle and the
damages may not be covered by
the vehicle's warranty. Always
use the correct fluid listed in
Recommended Fluids and
Lubricants on page 11‑12.
