Manual regeneration can only be
used when the DPF has become at
least 90% full. At 100% full, it will
attempt to automatically self-clean if
proper driving conditions are met.
The DPF will clean itself if the
vehicle can be driven for about
30 minutes.
A DIC message displays when
manual regeneration is possible.
Scroll through the DIC pages to find
the Exhaust Cleaning menu.
Depending on whether the vehicle
has a base or uplevel cluster, it may
be under the Settings menu.
If the vehicle cannot be stopped
when the DIC message first
indicates cleaning is available,
automatic self-cleaning may have
begun. If conditions cannot be met
for self-cleaning to complete, and
manual regeneration is selected, it
may take up to four minutes for the
system to switch to manual
regeneration. When the switch
occurs, a DIC message prompts to
start the cleaning process.{Warning
Do not leave the vehicle during
the regeneration.
Make sure that there are no
flammable materials near the
muffler, DPF, and exhaust pipe
which may result in a fire.
The temperature of exhaust
gases is high enough to burn you.
You and others could be seriously
injured.
Before starting manual
regeneration, make sure all of the
following safety conditions are met:
. The vehicle is parked on level
ground, away from any
flammable materials.
. The vehicle is parked outdoors,
away from any walls or
buildings.
. The vehicle is at least 3 m (10 ft)
from any obstructions or
materials that may combust
or melt. .
The shift lever is in P (Park).
. The fuel tank is at least
one-eighth full.
. All fluids are at the proper level.
. No diagnostic trouble codes
have been set, and the
malfunction indicator lamp is
not on.
. The engine coolant temperature
is above 71 °C (160 °F).
After making sure all safety
conditions have been met, press the
trip odometer reset stem or
thumbwheel on the steering wheel
for at least one second to select
Start on the infotainment display.
Follow the instructions in the DIC
messages. Touch ACCEPT to
acknowledge that all of these safety
conditions have been met and to
activate regeneration.
If the infotainment display returns to
the previous screen, then one or

The system will automatically
command downshifts to reduce
vehicle speed. The normal shift
pattern will return once the vehicle
is on a low grade or when the
accelerator pedal is pressed.
While in the Electronic Range
Select (ERS) mode, grade braking
is deactivated, allowing the driver to
select a range and limiting the
highest gear available. Grade
braking is available for normal
driving and in Tow/Haul Mode.

All-Wheel Drive
For information on All-Wheel
Drive (AWD), see Driver Mode
Control 0214.
Brakes
Antilock Brake
System (ABS)
The Antilock Brake System (ABS)
helps prevent a braking skid and
maintain steering while
braking hard.
ABS performs a system check when
the vehicle is first driven.
A momentary motor or clicking noise
may be heard while this test is going
on, and the brake pedal may move
slightly. This is normal.
If there is a problem with ABS, this
warning light stays on. See Antilock
Brake System (ABS) Warning Light
0 118.

Driving and Operating 207
ABS does not change the time
needed to get a foot on the brake
pedal and does not always
decrease stopping distance. If you
get too close to the vehicle ahead,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room ahead to stop,
even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly.
Hearing or feeling ABS operate is
normal.
Braking in Emergencies
ABS allows steering and braking at
the same time. In many
emergencies, steering can help
even more than braking.
Electric Parking Brake
The vehicle has an Electric Parking
Brake (EPB). The EPB can always
be activated, even if the ignition is
off. To prevent draining the battery,
avoid repeated cycles of the EPB
system when the engine is not
running.
The system has a
Yor PARK
Electric Parking Brake light, and a
8
Service Parking Brake light or
Service Parking Brake message. See
Electric Parking Brake Light
0 118 and
Service Electric Parking Brake Light
0 118.
Before leaving the vehicle, check for
the
Yor PARK light to ensure that
the parking brake is applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Press the EPB switch momentarily.
The
Yor PARK light will flash and
then stay on once the EPB is fully
applied. If the
Yor PARK light
flashes continuously, then the EPB
is only partially applied or there is a
problem with the EPB. A Driver
Information Center (DIC) message
will display. Release the EPB and
try to apply it again. If the light does
not come on, or keeps flashing,
have the vehicle serviced. Do not
drive the vehicle if the

stop the vehicle during the
parking maneuver.
Press
Oon the center console to
enable the system to search for a
parking space that is large enough
and within 1.5 m (5 ft) of the vehicle.
The vehicle speed must be below
30 km/h (18 mph). The system
cannot:
. Detect whether it is a legal
parking space.
. Park exactly lined up with the
vehicle next to it if the spot is
approached at an angle or if the
parking space is angled.
. Park exactly centered in a spot
that is marked too large.
. Always detect short curbs. When enabled, APA searches for
parallel parking spaces to the right
of the vehicle. To search for a
parking space to the left, turn on the
left turn signal or, if available,
change the side selection in the

If the vehicle is in R (Reverse), but
does not steer into the expected
space, this may be because the system is maneuvering the vehicle
into a previously detected space.
The APA system does not need
service.
APA will instruct the vehicle to stop
once a large enough space is found.
Follow the displayed instructions.
When instructed to drive in reverse,
shift to R (Reverse) to engage
automatic steering. The steering
wheel will briefly vibrate as a
