Before You Begin Programming HomeLink®
Be sure that your vehicle is parked outside of the garage
before you begin programming.For more efficient programming and accurate transmis-
sion of the radio-frequency signal it is recommended that
a new battery be placed in the hand-held transmitter of
the device that is being programmed to the HomeLink®
system.
To erase the channels place the ignition in the ON/RUN
position and push and hold the two outside HomeLink®
buttons (I and III) for up 20 seconds or until the red
indicator flashes.
NOTE:
•Erasing all channels should only be performed when
programming HomeLink® for the first time. Do not
erase channels when programming additional buttons.
•If you have any problems, or require assistance, please

NOTE:If your vehicle has experienced any damage in
the area where the sensor is located, even if the fascia is
not damaged, the sensor may have become misaligned.
Take your vehicle to an authorized dealer to verify sensor
alignment. Having a sensor that is misaligned will result
in the BSM not operating to specification.

CAUTION!(Continued)
damage is not covered by the New Vehicle Limited
Warranty.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.NOTE:
•Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
•Upon initial start-up in cold weather, the power steer-
ing pump may make noise for a short amount of time.
This is due to the cold, thick fluid in the steering
system. This noise should be considered normal, and it
does not in any way damage the steering system.
CAUTION!
Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.
422 STARTING AND OPERATING

WARNING!(Continued)
•Do not leave the Key Fob in or near the vehicle or
in a location accessible to children, and do not
leave the ignition of a vehicle equipped with
Keyless Enter-N-Go™ in the ACC or ON/RUN
mode. A child could operate power windows, other
controls, or move the vehicle.
•Be sure the parking brake is fully disengaged
before driving; failure to do so can lead to brake
failure and a collision.
•Always fully apply the parking brake when leav-
ing your vehicle, or it may roll and cause damage or
injury. Also be certain to leave the transmission in
PARK. Failure to do so may allow the vehicle to roll
and cause damage or injury.
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
