Lighting Features
Entry Lighting
Some exterior lamps and interior
lamps turn on briefly at night, or in
areas with limited lighting, when
K
is pressed on the Remote Keyless
Entry (RKE) transmitter. When a
door is opened, the interior lamps
come on. They stay on for about
20 seconds. When all of the doors
have been closed or the ignition is
turned on, they gradually fade out.
This feature can be changed. See
“Vehicle Locator Lights” under
Vehicle Personalization 0135.
Exit Lighting
Some exterior lamps and interior
lamps come on at night, or in areas
with limited lighting, when the driver
door is opened after the ignition is
turned off. The dome lamp comes
on after the ignition is turned off.
The exterior lamps and dome lamp
remain on for a set amount of time,
then automatically turn off.

Vehicle Personalization0135.
Battery Load
Management
The vehicle has Electric Power
Management (EPM) that estimates
the battery's temperature and state
of charge. It then adjusts the voltage
for best performance and extended
life of the battery.
When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), you may see the
voltage move up or down. This is
normal. If there is a problem, an
alert will be displayed. The battery can be discharged at
idle if the electrical loads are very
high. This is true for all vehicles.
This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all of the
power needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, rear
window defogger, climate control fan
at high speed, heated seats, engine
cooling fans, trailer loads, and loads
plugged into accessory power
outlets.
EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs.
It can increase engine idle speed to
generate more power whenever
needed. It can temporarily reduce
the power demands of some
accessories.
Normally, these actions occur in
steps or levels, without being
noticeable. In rare cases at the
highest levels of corrective action,this action may be noticeable to the
driver. If so, a DIC message might
be displayed and it is recommended
that the driver reduce the electrical
loads as much as possible.
Battery Power Protection
This feature shuts off the interior
lamps if they are left on for more
than 10 minutes when the ignition is
off. This helps to prevent the battery
from running down.
Exterior Lighting Battery
Saver
The exterior lamps turn off about
10 minutes after the ignition is
turned off, if the parking lamps or
headlamps have been manually left
on. This protects against draining
the battery. To restart the 10-minute
timer, turn the exterior lamp control
to the off position and then back to
the parking lamp or headlamp
position.
To keep the lamps on for more than
10 minutes, the ignition must be on
or in ACC/ACCESSORY.

{Warning
During DPF self-cleaning or
during extended idling in P (Park),
the exhaust system and exhaust
gases are very hot. Things that
burn could touch hot exhaust
parts under the vehicle and ignite.
You or others could be burned.
Do not park, or idle for an
extended period of time, near or
over papers, leaves, dry grass,
or other things that can burn.
Keep the exhaust area clear of
material that could ignite or burn.
SeeParking over Things That
Burn 0190.
Caution
Avoid extended idling because
the DPF system is not capable of
self-cleaning at idle. During
extended idling, monitor the
instrument cluster lights and DIC
(Continued)
Caution (Continued)
for messages and take
appropriate action. Continued
idling with the warning light/
message on could cause damage
to the DPF requiring repair and
possible replacement that might
not be covered by the vehicle
warranty.
During self-cleaning there will be a
change in the exhaust sound and
engine idle speed. Along with this, a
burning smell and reduction in fuel
economy may be noticed. This is
normal.
If the vehicle is idled or driven on
very short trips with the DPF
warning message on and the
exhaust filter is not cleaned as
required, the malfunction indicator
lamp and a DIC message will
display. See your dealer. Also see
Malfunction Indicator Lamp (Check
Engine Light) 0115. If equipped with Power
Take-Off (PTO), monitor the
instrument cluster for lights related
to the DPF.

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

{Warning
ACC has limited braking ability
and may not have time to slow
the vehicle down enough to avoid
a collision with another vehicle
you are following. This can occur
when vehicles suddenly slow or
stop ahead, or enter your lane.
Also see“Alerting the Driver” later
in this section. Complete attention
is always required while driving
and you should be ready to take
action and apply the brakes. See
Defensive Driving 0164.
{Warning
ACC will not detect or brake for
children, pedestrians, animals,
or other objects.
