To signal a lane change, raise or lower the
lever until the arrow starts to flash. The

The lever returns to its starting position
when released.
If after signaling a turn or lane change the
arrow flashes rapidly or does not come on, a
signal bulb may be burned out.
Have any burned out bulbs replaced. If a
bulb is not burned out, check the fuse. See
Fuses and Circuit Breakers 0198.

active. See Retained Accessory Power (RAP)
0 133.
A warning chime will sound when the driver
door is opened and the key is in the
ignition.
If equipped with a locking steering column,
the steering can bind with the front wheels
turned off center, which may prevent key
rotation out of LOCK/OFF. If this happens,
move the steering wheel from right to left
while turning the key to ACC/ACCESSORY.
If this does not work, then the vehicle needs
service.
{Warning
Turning off the vehicle while moving may
cause loss of power assist in the brake

pulled over and must be turned off while
driving:
1. Push the key all the way in toward the steering column, then turn the key to
ACC/ACCESSORY.
2. Brake using firm and steady pressure. Do not pump the brakes repeatedly. This
may deplete power assist, requiring
increased brake pedal force.
3. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving.
Continue braking and steer the vehicle to
a safe location.
4. Come to a complete stop.
5. Shift to P (Park).

An obstacle detection is indicated by beeps.
The time between beeps gets shorter as the
vehicle approaches the obstacle. Repeated
beeps are heard when the distance is less
than 30 cm (12 in).
To be detected, objects must be at least
25 cm (10 in) off the ground and below rear
door level. Objects must also be within 2.5 m
(8 ft) from the rear bumper. This distance
may be less during warmer or humid
weather.

When the System Does Not Seem to
Work Properly
The following messages may be displayed
on the DIC:
SERVICE PARK ASSIST : If this message
occurs, take the vehicle to your dealer for
repair. PARK ASSIST OFF :
This message occurs if
the driver disables the system or if the
vehicle is driven above 8 km/h (5 mph) in
R (Reverse).
PARK ASST BLOCKED SEE OWNERS
MANUAL : This message can occur under the
following conditions:
.The sensors are not clean. Keep the rear
bumper free of mud, dirt, snow, ice, slush,
and frost. The message may not clear
until frost or ice has melted all around
and inside the sensor.
.A trailer is attached to the vehicle, or a
bicycle or an object hanging out of the
rear door during the current or last drive
cycle. RPA will return to normal operation
after it is determined the object is
removed. This could take a few drive
cycles.
.A tow bar is attached to the vehicle.
Other conditions may affect system
performance, such as vibrations from a
jackhammer or the compression of air
brakes on a very large truck.
Forward Collision Alert (FCA)
System
If equipped, the FCA system may help to
avoid or reduce the harm caused by
front-end crashes. When approaching a
vehicle ahead too quickly, FCA provides a
red flashing alert on the windshield and
rapidly beeps. FCA also lights an amber
visual alert if following another vehicle
much too closely.
FCA detects vehicles within a distance of
approximately 60 m (197 ft) and operates at
speeds above 40 km/h (25 mph).
{Warning
FCA is a warning system and does not
apply the brakes. When approaching a
slower-moving or stopped vehicle ahead
too rapidly, or when following a vehicle
too closely, FCA may not provide a
warning with enough time to help avoid
a crash. It also may not provide any
warning at all. FCA does not warn of
pedestrians, animals, signs, guardrails,
bridges, construction barrels, or other (Continued)

Warning (Continued)
.Before touching the fill nozzle, touch a
metallic object to discharge static
electricity from your body.
.Fuel can spray out if the fuel cap is
opened too quickly. This spray can
happen if the tank is nearly full, and is
more likely in hot weather. Open the
fuel cap slowly and wait for any hiss
noise to stop, then unscrew the cap all
the way.
Turn the fuel cap counterclockwise to
remove. When refueling, hang the fuel cap
from the hook on the fuel door. Fully insert
and latch the fill nozzle, begin fueling.
{Warning
Overfilling the fuel tank by more than
three clicks of a standard fill nozzle may
cause:
.Vehicle performance issues, including
engine stalling and damage to the fuel
system.
.Fuel spills.
.Under certain conditions, fuel fires.
Be careful not to spill fuel. Wait five seconds
after you have finished pumping before
removing the fill nozzle. Clean fuel from
painted surfaces as soon as possible. See
Exterior Care 0233. Reinstall the cap by
turning it clockwise until it clicks. Push the
fuel door closed.
{Warning
If a fire starts while you are refueling, do
not remove the fill nozzle. Shut off the
flow of fuel by shutting off the pump or
by notifying the station attendant. Leave
the area immediately.
Caution
If a new fuel cap is needed, get the right
type of cap from your dealer. The wrong
type of fuel cap may not fit properly,
may turn on the malfunction indicator
lamp, and could damage the fuel system
and emissions system. See Malfunction
Indicator Lamp (Check Engine Light) 077.
Filling a Portable Fuel Container
{Warning
Never fill a portable fuel container while
it is in the vehicle. Static electricity
discharge from the container can ignite
the fuel vapor. You or others could be
badly burned and the vehicle could be
damaged. To help avoid injury to you
and others:
.Dispense fuel only into approved
containers.
.Do not fill a container while it is
inside a vehicle, in a vehicle's trunk, in
a pickup bed, or on any surface other
than the ground.
