GETTING TO KNOW YOUR INSTRUMENT PANEL 145
Loss of the battery charge may indicate one or more of the
following conditions:
• The charging system cannot deliver enough electricalpower 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, overloaded power
outlets +12V, 115V AC, USB ports) during certain driving
conditions (city driving, towing, frequent stopping).

• Installing options like additional lights, upfitter electrical 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, +12V
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 +12V,115V AC, USB ports.
• Check HVAC settings (blower, temperature).
• Check the audio settings (volume).
After a trip:
• Check if any aftermarket equipment was installed (addi -
tional 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.

IN CASE OF EMERGENCY 395
5. Remove the lug nuts and pull the wheel off. Install thespare wheel and lug nuts with the cone shaped end of the
nuts toward the wheel on single rear wheel (SRW)
models. On dual rear wheel models (DRW) the lug nuts
are a two-piece assembly with a flat face. Lightly tighten
the nuts. To avoid risk of forcing the vehicle off the jack,
do not fully tighten the nuts until the vehicle has been
lowered.
6. Using the lug wrench, finish tightening the nuts using a crisscross pattern. For the proper lug nut torque specifica -
tions refer to “Wheel And Tire Torque Specifications” in
“Technical Specifications.” If in doubt about the correct
tightness, have them checked with a torque wrench by an
authorized dealer or at a service station. 7. Install wheel center cap (if equipped) and remove wheel
blocks. Do not install chrome or aluminum wheel center
caps on the spare wheel. This may result in cap damage.
8. Lower the jack to its fully closed position. If the jack will not lower by turning the dial (thumbwheel) by hand, it
may be necessary to use the jack driver in order to lower
the jack. Stow the replaced tire, jack, and tools as previ -
ously described.
9. Adjust the tire pressure when possible.
WARNING!
Raising the vehicle higher than necessary can make the
vehicle less stable. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to
remove the tire.WARNING!
A loose tire or jack thrown forward in a collision or hard
stop, could endanger the occupants of the vehicle.
Always stow the jack parts and the spare tire in the
places provided.

Wheel Mounting Surface
Retighten the wheel nuts in the same sequence to the torques
listed in the table. Go through the sequence a second time to
verify that specific torque has been achieved. Retighten to
specifications after 25 miles (40 km) and check the lug nut/
bolt torque to be sure that all the lug nuts/bolts are properly
seated against the wheel. 8/10 Lug Nuts/Bolts Torque Patterns
It is recommended that wheel stud nuts be kept torqued to
specifications at all times. Torque wheel stud nuts to specifi -
cations at each lubrication interval.
All wheel nuts should be tightened occasionally to eliminate
the possibility of wheel studs being sheared or the bolt holes
in the wheels becoming elongated. This is especially
important during the first few hundred miles/kilometers of
operation to allow the wheel nuts to become properly set. All
wheel nuts should first be firmly seated against the wheel.
