Lighting 137
Rear Reading Lamps
Press the buttons to turn the rear passenger
reading lamps on or off.
Lighting Features
Entry Lighting
The interior lamps turn on when pressingK
on the Remote Keyless Entry (RKE)
transmitter or opening any doors, and the
dome lamp control is in the DOOR position.
Some exterior lamps also turn on when
pressing
Kon the RKE transmitter or
opening any doors. Low-Beam lamps will
only turn on briefly at night, or in areas
with limited lighting.
All lamps will gradually fade out after about
30 seconds. Entry lighting can be disabled manually by
closing all doors, pressing
Qon the RKE
transmitter, or starting the vehicle.
This feature can be changed. See “Vehicle
Locator Lights” underVehicle Personalization
0 124.
Exit Lighting
Some exterior lamps and interior lamps turn
on when the key is removed from the
ignition.
The exterior and interior lamps remain on
for a set amount of time, then automatically
turn off. If equipped with Keyless Access,
the exterior lamps automatically turn on
when the driver door is opened after the
ignition is turned off.
The interior lights turn on when the ignition
is turned off.
The exterior lamps turn off immediately by
turning the exterior lamp control off.
This feature can be changed. See Vehicle
Personalization 0124.
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.

Driving and Operating 213
Caution (Continued)
.Avoid making hard stops for the first
300 km (200 mi) or so. During this
time the new brake linings are not yet
broken in. Hard stops with new linings
can mean premature wear and earlier
replacement. Follow this breaking-in
guideline every time you get new
brake linings.
.Do not tow a trailer during break-in.
SeeTrailer Towing 0261 for the trailer
towing capabilities of the vehicle and
more information.
Following break-in, engine speed and load
can be gradually increased.
On new vehicles, the various mechanical and
electrical systems experience a “break-in”
period during the first 6 400 km (4,000 mi)
of routine driving. As the vehicle is driven,
the mechanical systems adjust to provide
optimal fuel economy and transmission shift
performance.
Electrical systems will adapt and calibrate
during the break-in period. A one-time
occurrence of clicks and similar vehicle
noises is normal during this process. Normal driving charges the vehicle’s battery
to achieve the best operation of the vehicle,
including fuel economy and the Stop/Start
System. See
Stop/Start System 0215.
Ignition Positions
The vehicle has an electronic keyless ignition
with pushbutton start.
The Remote Keyless Entry (RKE) transmitter
must be in the vehicle for the system to
operate. If the pushbutton start is not
working, the vehicle may be near a strong
radio antenna signal causing interference to
the Remote Keyless Entry (RKE) system. See
Remote Keyless Entry (RKE) System
Operation 07. To shift out of P (Park), the vehicle must be
on and the brake pedal must be applied.
Stopping the Engine/LOCK/OFF (No Indicator
Lights) :
When the vehicle is stopped, press
ENGINE START/STOP once to turn the
engine off.
If the vehicle is in P (Park), the ignition will
turn off, and Retained Accessory Power (RAP)
will remain active. See Retained Accessory
Power (RAP) 0217.
If the vehicle is in R (Reverse), D (Drive) or
L (Low), the vehicle will shift to P (Park), the
ignition will turn off, and Retained Accessory
Power (RAP) will remain active. If the vehicle
is in N (Neutral), the ignition will return to
ACC/ACCESSORY and display the message
SHIFT TO PARK in the Driver Information
Center (DIC). When the vehicle is shifted
into P (Park), the ignition will turn off.
Do not turn the engine off when the vehicle
is moving. This will cause a loss of power
assist in the brake and steering systems and
disable the airbags.

Mexico-15170041) - 2022 - CRC - 10/6/21
Driving and Operating 215
Starting Procedure
1. With the Keyless Access system, the RKEtransmitter must be in the vehicle. Press
ENGINE START/STOP with the brake pedal
applied. When the engine begins
cranking, let go of the button.
The idle speed will go down as the
engine gets warm. Do not race the
engine immediately after starting it.
If the RKE transmitter is not in the
vehicle, if there is interference, or if the
RKE battery is low, the Driver
Information Center (DIC) will display a
message.
Caution
Cranking the engine for long periods of
time, by trying to start the engine
immediately after cranking has ended,
can overheat and damage the cranking
motor, and drain the battery. Wait at
least 15 seconds between each try, to let
the cranking motor cool down.
2. 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 and holding it there as you
press ENGINE START/STOP, for up to a
maximum of 15 seconds. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down. When
the engine starts, let go of the button
and the accelerator. If the vehicle starts
briefly but then stops again, do the
same thing. This clears the extra gasoline
from the engine. 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.
Stop/Start System
The Stop/Start system will shut off the
engine to help conserve fuel. It has
components designed for the increased
number of starts.
{Warning
The automatic engine Stop/Start feature
causes the engine to shut off while the
vehicle is still on. Do not exit the vehicle
before shifting to P (Park). The vehicle
may restart and move unexpectedly.
Always shift to P (Park), and then turn
the ignition off before exiting the vehicle.
Auto Engine Stop/Start
When the brakes are applied and the vehicle
is at a complete stop, the engine may turn
off. When stopped, the tachometer displays
AUTO STOP. See
Tachometer0103. When
the brake pedal is released or the
accelerator pedal is pressed, the engine will
restart.
To maintain vehicle performance, other
conditions may cause the engine to
automatically restart before the brake pedal
is released.
Auto Stops may not occur and/or auto
restarts may occur because:
.The climate control settings require the
engine to be running to cool or heat the
vehicle interior.
.The vehicle battery needs to charge.
.The vehicle battery has recently been
disconnected.
.Minimum vehicle speed has not been
reached since the last Auto Stop
.The accelerator pedal is pressed.
.The engine or transmission is not at the
required operating temperature.
.The outside temperature is not in the
required operating range.
