Lighting Features
Entry Lighting
Some exterior lamps and the interior lamps
turn on briefly at night, or in areas with
limited lighting, when
Kis pressed on the
Remote Keyless Entry (RKE) transmitter.
When a door is opened, the interior lamps
come on if the dome lamp control is in the
Hposition. After about 30 seconds the
exterior lamps turn off. Entry lighting can be
disabled manually by changing the ignition
out of the OFF position, or by pressing
Q
on the RKE transmitter.
This feature can be changed. See “Vehicle
Locator Lights” underVehicle Personalization
0 98.
Exit Lighting
Some exterior lamps and the interior lamps
come on at night, or in areas with limited
lighting when the key is removed from the
ignition. The exterior and interior lamps
remain on for a set amount of time and
then automatically turn off. The interior
lamps do not come on if the dome lamp
control is in the Off position. The exterior lamps turn off immediately by
turning the exterior lamps control off.
This feature can be changed. See
Vehicle
Personalization 098.
Battery Load Management
The vehicle has Electric Power Management
(EPM), which 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. The
voltmeter gauge or the voltage display on
the Driver Information Center (DIC),
if equipped, may show the voltage moving
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 the power that
is needed for very high electrical loads. A high electrical load occurs when several of
the following are on, such as: headlamps,
high beams, fog lamps, 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 dome and reading
lamps, if they are left on for more than
10 minutes after the ignition is turned off.

Lighting 107
The cargo lamp shuts off after 20 minutes.
This prevents 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
Oposition
and then back to the
;or2position.
To keep the lamps on for more than
10 minutes, the ignition must be on or in
ACC/ACCESSORY.

134 Infotainment System
.The GPS signal is not received.
.A roof carrier is installed on the vehicle.
.Tire chains are installed on the vehicle.
.The tires are replaced or worn.
.The tire pressure for the tires is incorrect.
.This is the first navigation use after the
map data is updated.
.The 12-volt battery has been disconnected
for several days.
.The vehicle is driving in heavy traffic
where driving is at low speeds, and the
vehicle is stopped and started repeatedly.
Problems with Route Guidance
Inappropriate route guidance can occur
under one or more of the following
conditions:
.The turn was not made on the road
indicated.
.Route guidance might not be available
when using automatic rerouting for the
next right or left turn.
.The route might not be changed when
using automatic rerouting.
.There is no route guidance when turning
at an intersection.
.Plural names of places might be
announced occasionally.
.It could take a long time to operate
automatic rerouting during high-speed
driving.
.Automatic rerouting might display a route
returning to the set waypoint if heading
for a destination without passing through
a set waypoint.
.The route prohibits the entry of a vehicle
due to a regulation by time or season or
any other regulation which may be given.
.Some routes might not be searched.
.The route to the destination might not be
shown if there are new roads, if roads
have recently changed, or if certain roads
are not listed in the map data. SeeMaps
0 126.
To recalibrate the vehicle's position on the
map, park with the vehicle running for two
to five minutes, until the vehicle position
updates. Make sure the vehicle is parked in
a location that is safe and has a clear view
of the sky and away from large
obstructions.
If the System Needs Service
If the navigation system needs service, see
your dealer.
Map Data Updates
The map data in the vehicle is the most
up-to-date information available when the
vehicle was produced. The map data is
updated periodically, provided that the map
information has changed and the vehicle has
a relevant service plan.
Over-the-Air-Vehicle Map Updates
If equipped, the infotainment system can
receive map updates over the air. Map
updates occur within a 161 km (100 mi)
radius around the home address on file. This
boundary will adjust over time based on
driving patterns. The vehicle uses a
Cloud-connected service to receive the date
and downloads it to the system’s onboard
SD card, if equipped. A data plan or
compatible mobile device hotspot is
required. The SD card is required for
navigation system function.
When a map update is available, a prompt
will appear on the infotainment display.
Once the update is accepted, it will
download and run in the background
without interruption any infotainment
functions. The download will carry over

178 Driving and Operating
For Slippery Road Driving:
.Accelerate gently. Accelerating too quickly
causes the wheels to spin and makes the
surface under the tires slick.
.Turn on Traction Control. SeeTraction
Control/Electronic Stability Control 0202.
.The Antilock Brake System (ABS) improves
vehicle stability during hard stops, but
the brakes should be applied sooner than
when on dry pavement. See Antilock
Brake System (ABS) 0201.
.Allow greater following distance and
watch for slippery spots. Icy patches can
occur on otherwise clear roads in shaded
areas. The surface of a curve or an
overpass can remain icy when the
surrounding roads are clear. Avoid sudden
steering maneuvers and braking while
on ice.
.Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place and signal
for help. Stay with the vehicle unless there
is help nearby. If possible, use Roadside
Assistance. See Roadside Assistance Program
0 331. To get help and keep everyone in the
vehicle safe:
.Turn on the hazard warning flashers.
.Tie a red cloth to an outside mirror.
{Warning
Snow can trap engine exhaust under the
vehicle. This may cause exhaust gases to
get inside. Engine exhaust contains
carbon monoxide (CO), which cannot be
seen or smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in snow:
.Clear snow from the base of the
vehicle, especially any blocking the
exhaust pipe.
.Open a window about 5 cm (2 in) on
the vehicle side that is away from the
wind, to bring in fresh air.
.Fully open the air outlets on or under
the instrument panel.
.Adjust the climate control system to
circulate the air inside the vehicle and
set the fan speed to the highest
setting. See “Climate Control Systems.”
For more information about CO, see
Engine Exhaust 0190. To save fuel, run the engine for short
periods to warm the vehicle and then shut
the engine off and partially close the
window. Moving about to keep warm also
helps.
If it takes time for help to arrive, when
running the engine, push the accelerator
pedal slightly so the engine runs faster than
the idle speed. This keeps the battery
charged to restart the vehicle and to signal
for help with the headlamps. Do this as
little as possible, to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the wheels to
free the vehicle when stuck in sand, mud,
ice, or snow. See
“Rocking the Vehicle to Get
It Out” later in this section.
If equipped, the front and rear axles may be
locked to improve traction. See Locking Front
Axle 0207 and
Locking Rear Axle 0206.
The Traction Control System (TCS) can often
help to free a stuck vehicle. See Traction
Control/Electronic Stability Control 0202.
If TCS cannot free the vehicle, see “Rocking
the Vehicle to Get it Out” following.
