DRIVING AND OPERATING 285
When electrical grid power is
completely blocked, the vehicle will
delay charging until the utility
interruption has expired. The vehicle
should be left plugged in so that the
vehicle can automatically begin
charging.
Changing the charge mode to
Immediate or performing a delayed
charging override will not disable a
utility interruption.
A pop-up will appear in the
infotainment display during the key
cycle following any utility
interruption. See“Charging
Interrupted or Overridden Pop-Up ”
under Programmable Charging
(PLUG-IN Only) 0152.
A message will display on the
instrument cluster indicating that a
utility interruption has occurred.
See Instrument Cluster (Base Level)
0 127 orInstrument Cluster (Uplevel)
0 130.Charging Station
Troubleshooting
If the vehicle does not charge after
being plugged in to a residential
240-volt charging station:
1. Verify that the charge mode is set to Immediate.
2. Verify that the charging station’s circuit breaker has not been
tripped.
3. Plug the portable charge cord into the wall outlet, verify that
the indicator light on the charge
cord is solid green, and connect
it to the vehicle. See “Charge
Cord Status Indicators ”in Charge
Cord (PLUG-IN Only) 0279.
4. If the vehicle charges with the portable charge cord, there may
be a problem with the charging
station. Try to charge the vehicle
with a different 240-volt charging
station, such as a public station.
If both attempts charge the
vehicle, contact the charging
station manufacturer.

Doing Your Own
Service Work
{Warning
It can be dangerous to work on
your vehicle if you do not have the
proper knowledge, service manual,
tools, or parts. Always follow
owner’s manual procedures and
consult the service manual for your
vehicle before doing any
service work.
If doing some of your own service
work, use the proper service manual.
It tells you much more about how to
service the vehicle than this manual
can. To order the proper service
manual, see Service Publications
Ordering Information 0416.
This vehicle has an airbag system.

VEHICLE CARE 383
Caution
Using petroleum-based tire dressing
products on the vehicle may
damage the paint finish and/or
tires. When applying a tire dressing,
always wipe off any overspray from
all painted surfaces on the vehicle.
Wheels and Trim—Aluminum or
Chrome
Use a soft, clean cloth with mild soap
and water to clean the wheels. After
rinsing thoroughly with clean water,
dry with a soft, clean towel. A wax
may then be applied.
Caution
Chrome wheels and other chrome
trim may be damaged if the vehicle
is not washed after driving on roads
that have been sprayed with
magnesium, calcium, or sodium
chloride. These chlorides are used
on roads for conditions such as ice
and dust. Always wash the chrome
with soap and water after exposure.
Caution
To avoid surface damage, do not
use strong soaps, chemicals,
abrasive polishes, cleaners, brushes,
or cleaners that contain acid on
aluminum or chrome-plated wheels.
Use only approved cleaners. Also,
never drive a vehicle with
aluminum or chrome-plated wheels
through an automatic car wash that
uses silicone carbide tire cleaning
brushes. Damage could occur and
the repairs would not be covered by
the vehicle warranty.
Brake System
Visually inspect brake lines and hoses
for proper hook-up, binding, leaks,
cracks, chafing, etc. Inspect disc brake
pads for wear and rotors for surface
condition. Inspect brake linings/shoes
for wear or cracks. Inspect all other
brake parts.
Steering, Suspension, and
Chassis Components
Visually inspect steering, suspension,
and chassis components for damaged,
loose, or missing parts or signs of
wear at least once a year.
Inspect power steering for proper
attachment, connections, binding,
leaks, cracks, chafing, etc.
Visually check constant velocity joint
boots and axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders, hood
hinges, liftgate hinges, and the steel
fuel door hinges, unless the
components are plastic. Applying
silicone grease on weatherstrips with a
clean cloth will make them last
longer, seal better, and not stick or
squeak.
Underbody Maintenance
At least twice a year, spring and fall,
use plain water to flush any corrosive
materials from the underbody. Take
care to thoroughly clean any areas
where mud and other debris can
collect.
