Lighting Features
Entry Lighting
Some exterior lamps and interior lamps turn
on briefly at night, or in areas with limited
lighting, when
Kis pressed on the Remote
Keyless Entry (RKE) transmitter. After about
30 seconds the exterior lamps turn off.
Entry lighting can be disabled manually by
turning the ignition on or to ACC/
ACCESSORY, or by pressing
Qon the RKE
transmitter. When any door is opened or
remote unlock pressed, all interior lights
turn on and then interior lamps dim to off
after 20 seconds.
The entry lighting feature for exterior
lighting can be changed. See “Vehicle
Locator Lights” underVehicle Personalization
0 104.
Exit Lighting
Some exterior lamps come on at night or in
areas with limited lighting when the driver
door is opened after the ignition is
turned off.
The interior lamps come on after the
ignition is turned off or any door is opened. The exterior and interior lamps remain on
after the door is closed for a set amount of
time then automatically turn off.
Exit lighting for exterior lights can be
changed. See
Vehicle Personalization 0104.
Theater Dimming
This feature allows for a three to five
second fade out of the interior lamps
instead of having them turn off
immediately.
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.

Driving and Operating 201
Mode. The instruments and audio systems
will operate as they do in ON/RUN, but the
vehicle will not be able to be driven. The
engine will not start in Service Mode. Press
the button again to turn the vehicle off.
Starting the Engine
Place the transmission in the proper gear.
Caution
If you add electrical parts or accessories,
you could change the way the engine
operates. Any resulting damage would
not be covered by the vehicle warranty.
SeeAdd-On Electrical Equipment 0233.
Automatic Transmission
Move the shift lever to P (Park) or
N (Neutral). To restart the vehicle when it is
already moving, use N (Neutral) only.
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you could
damage the transmission. Shift to P (Park)
only when the vehicle is stopped. Manual Transmission
The shift lever should be in Neutral and the
parking brake engaged. Hold the clutch
pedal down to the floor, press the brake
pedal, and start the engine.
Starting the Vehicle
The RKE transmitter must be inside the
vehicle for the ignition to work.
Cell phone chargers can interfere with the
operation of the Keyless Access system.
Battery chargers should not be plugged in
when starting or turning off the engine.
To start the vehicle:
1. For vehicles with an automatic transmission, press the brake pedal, then
press ENGINE START/STOP on the
instrument panel. For a manual
transmission, place the shift lever in
Neutral with the parking brake engaged.
Hold the clutch pedal down to the floor,
press the brake pedal, then press ENGINE
START/STOP.
If there is no RKE transmitter in the
vehicle or if there is something causing
interference with it, the Driver
Information Center (DIC) will display a
message. 2. When the engine begins cranking, let go
of the button and the engine cranks
automatically until it starts. If the
battery in the RKE transmitter is weak,
the DIC will display a message. The
vehicle can still be driven.
See “Starting the Vehicle with a Low
Transmitter Battery” underRemote
Keyless Entry (RKE) System Operation 07
. If the RKE transmitter battery is dead,
insert it into the rear cupholder to
enable engine starting.
3. Do not race the engine immediately after starting it. Operate the engine and
transmission gently until the oil warms
up and lubricates all moving parts.
4. If the engine does not start and no DIC message is displayed, wait 15 seconds
before trying again to let the cranking
motor cool down.
If the engine does not start after five to
10 seconds, especially in very cold
weather (below −18 °C or 0 °F), it could
be flooded with too much gasoline. Try
pushing the accelerator pedal all the way
to the floor while cranking for up to
15 seconds maximum. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down. When
