(136 kg), and should be uniformly distributed over the
load floor.
Additional storage can be found under the storage lid. To
access the lower storage, lift the handle and raise the
storage lid.

Lift Load Floor Handle

Cargo Tie-Down Hooks
The cargo tie-downs, located on the cargo area sides,
should be used to safely secure loads when the vehicle is
moving. The cargo tie downs are designed for a maximum
load of 300 lb (136 kg) per tie-down.

Tie-Down Hooks

WARNING!

Cargo tie-downs are not safe anchors for a child seat
tether strap. In a sudden stop or accident, a tie-down
could pull loose and allow the child seat to come loose.
A child could be badly injured. Use only the anchors
provided for child seat tethers.
 To help protect against personal injury, passengers
should not be seated in the rear cargo area. The rear
cargo space is intended for load carrying purposes only,
not for passengers, who should sit in seats and use seat
belts.
The weight and position of cargo and passengers can
change the vehicle center of gravity and vehicle handling.
To avoid loss of control resulting in personal injury, follow
these guidelines for loading your vehicle:
Do not carry loads that exceed the load limits described
on the label attached to the left door or left door center
pillar.
 Always place cargo evenly on the cargo floor. Put
heavier objects as low and as far forward as possible.
 Place as much cargo as possible in front of the rear axle.
Too much weight or improperly placed weight over or
behind the rear axle can cause the vehicle to sway.
 Do not pile luggage or cargo higher than the top of the
seatback. This could impair visibility or become a
dangerous projectile in a sudden stop or accident.

6. Repeat steps 2-5 for the second crossbar in the
desired position.

Installed Crossbars

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 or
roof rack.
CAUTION!
To prevent damage to the roof of your vehicle, DO
NOT carry any loads on the roof rack without the
crossbars installed. 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 crossbars 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!

108GETTING TO KNOW YOUR INSTRUMENT PANEL
When load reduction is activated, the message “Battery
Saver On” or “Battery Saver Mode” will appear in the
instrument cluster.
These messages indicate the vehicle battery has a low
state of charge and continues to lose electrical charge at
a rate that the charging system cannot sustain.
NOTE:
The charging system is independent from load reduc -
tion. The charging system performs a diagnostic on the
charging system continuously.
 If the Battery Charge Warning Light is on it may indicate
a problem with the charging system
Úpage 109.
The electrical loads that may be switched off (if equipped),
and vehicle functions which can be affected by load
reduction:
 Heated Seat/Vented Seats/Heated Wheel
 Rear Defroster And Heated Mirrors
 HVAC System
 115 Volt 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 the 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 Volt, 115 Volt AC, USB ports)
during certain driving conditions (city driving, towing,
frequent stopping, etc.).
 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 Volt, 115 Volt AC, 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 if
the evaluation and driving pattern of the vehicle did not
help to identify the cause.WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the
instrument panel together with a dedicated message and/
or acoustic signal when applicable. These indications are
indicative and precautionary and as such must not be
considered as exhaustive and/or alternative to the
information contained in the Owner’s Manual, which you
