STOW ‘N PLACE ROOF RACK — IF EQUIPPED
The crossbars and side rails are designed to carry weight
on vehicles equipped with a luggage rack. The load must
not exceed 150 lb (68 kg), and should be uniformly
distributed over the luggage rack crossbars.
The crossbars on your vehicle are delivered stowed within
the roof rack side rails. Crossbars should always be used
whenever cargo is placed on the roof rack. Check the
straps frequently to be sure that the load remains securely
attached.

(Continued)
NOTE:
To help control wind noise, stow the crossbars in the
side rails when they are not in use.
 If any metallic object is placed over the satellite radio
antenna (if equipped), you may experience interruption
of satellite radio reception.
WARNING!
Cargo must be securely tied down before driving your
vehicle. Anything improperly secured to the roof rack,
crossbars, or the roof itself can fly off the vehicle,
particularly at high speeds, resulting in collisions,
personal injury, or property damage. Follow the roof
rack cautions when carrying anything on your roof rack.
CAUTION!
To prevent damage to the roof of your vehicle, DO
NOT carry any loads on the roof rack without the
crossbars deployed. The load should be secured and
placed on top of the crossbars, not directly on the
roof. If it is necessary to place the load on the roof,
place a blanket or other protective layer between the
load and the roof surface.
 To avoid damage to the roof rack and vehicle, do not
exceed the maximum roof rack load capacity of 150
lb (68 kg). Always distribute heavy loads as evenly as
possible and appropriately secure the load and any
protective layer placed between the load and the roof
surface.Load should always be secured to cross bars first,
with tie down loops used as additional securing
points if needed. Tie loops are intended as supple -
mentary tie down points only. Do not use ratcheting
mechanisms with the tie loops. Check the straps and
thumb wheels frequently to be sure that the load
remains securely attached.
 Long loads that extend over the windshield, such as
wood panels or surfboards, or loads with large frontal
area should be secured to both the front and rear of
the vehicle.
 Travel at reduced speeds and turn corners carefully
when carrying large or heavy loads on the roof rack.
Wind forces, due to natural causes or nearby truck
traffic, can add sudden upward lift to a load. This is
especially true on large flat loads and may result in
damage to the cargo or your vehicle.
CAUTION!

 Heated Seat/Vented Seats/Heated Wheel
 Heated/Cooled Cup Holders — If Equipped
 Rear Defroster And Heated Mirrors
 HVAC System
 115 Volts AC Power Inverter System
 Audio and Telematics System
Loss of the battery charge may indicate one or more of the
following conditions:
 The charging system cannot deliver enough electrical
power to the vehicle system because the electrical
loads are larger than the capability of charging system.
The charging system is still functioning properly.
 Turning on all possible vehicle electrical loads (e.g.
HVAC to max settings, exterior and interior lights, over -
loaded power outlets +12 Volts, 150W, USB ports)
during certain driving conditions (city driving, towing,
frequent stopping).
 Installing options like additional lights, upfitter elec -
trical accessories, audio systems, alarms and similar
devices. 
Unusual driving cycles (short trips separated by long
parking periods).
 The vehicle was parked for an extended period of time
(weeks, months).
 The battery was recently replaced and was not charged
completely.
 The battery was discharged by an electrical load left on
when the vehicle was parked.
 The battery was used for an extended period with the
engine not running to supply radio, lights, chargers,
+12 Volt portable appliances like vacuum cleaners,
game consoles and similar devices.
What to do when an electrical load reduction action
message is present (“Battery Saver On” or “Battery Saver
Mode”)
During a trip:
 Reduce power to unnecessary loads if possible:
 Turn off redundant lights (interior or exterior)
 Check what may be plugged in to power outlets
+12 Volts, 150W, USB ports
 Check HVAC settings (blower, temperature)
 Check the audio settings (volume)
After a trip:
 Check if any aftermarket equipment was installed
(additional lights, upfitter electrical accessories, audio
systems, alarms) and review specifications if any (load
and Ignition Off Draw currents). 
Evaluate the latest driving cycles (distance, driving
time and parking time).
 The vehicle should have service performed if the
message is still present during consecutive trips and
the evaluation of the vehicle and driving pattern did not
help to identify the cause.

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as emissions well
within current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Although
your vehicle will usually be drivable and not need towing,
see an authorized dealer for service as soon as possible.
ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have OBD II and a connection
port to allow access to information related to the
performance of your emissions controls. Authorized
service technicians may need to access this information to
assist with the diagnosis and service of your vehicle and
emissions system
Úpage 157.
CAUTION!
 Prolonged driving with the MIL on could cause further
damage to the emission control system. It could also
affect fuel economy and driveability. The vehicle
must be serviced before any emissions tests can be
performed.
 If the MIL is flashing while the vehicle is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
WARNING!
ONLY an authorized service technician should
connect equipment to the OBD II connection port in
order to read the VIN, diagnose, or service your
vehicle.
 If unauthorized equipment is connected to the OBD II
connection port, such as a driver-behavior tracking
device, it may:
 Be possible that vehicle systems, including
safety related systems, could be impaired or a
loss of vehicle control could occur that may
result in an accident involving serious injury or
death.
 Access, or allow others to access, information
stored in your vehicle systems, including
personal information.
