Maintenance-Free Battery
Your vehicle is equipped with a mainte
-
nance-free battery. You will never have to
add water, nor is periodic maintenance
required.
Pressure Washing
WARNING!
Battery fluid is a corrosive acid solution
and can burn or even blind you. Do not
allow battery fluid to contact your eyes,
skin, or clothing. Do not lean over a
battery when attaching clamps. If acid
splashes in eyes or on skin, flush the
area immediately with large amounts of
water. Refer to “Jump Starting Proce-
dure” in “In Case Of Emergency” for
further information.
Battery gas is flammable and explosive.
Keep flame or sparks away from the
battery. Do not use a booster battery or
any other booster source with an output
greater than 12 Volts. Do not allow cable
clamps to touch each other.
Battery posts, terminals, and related
accessories contain lead and lead
compounds. Wash hands after handling.

Vehicles with the Stop/Start system will be
equipped with two batteries. Bot the main
and the supplemental batteries must be
disconnected to completely de-energize the
12 volt electrical system.

Serious injury or death could result if you
do not disconnect both batteries. To
learn how to properly disconnect, see
your authorized dealer.
CAUTION!
It is essential when replacing the cables
on the battery that the positive cable is
attached to the positive post and the
negative cable is attached to the nega-
tive post. Battery posts are marked posi -
tive (+) and negative (-) and are
identified on the battery case. Cable
clamps should be tight on the terminal
posts and free of corrosion.

If a “fast charger” is used while the battery is
in the vehicle, disconnect both vehicle
battery cables before connecting the charger
to the battery. Do not use a “fast charger” to
provide starting voltage.

WARNING! (Continued)
Vehicles with the Stop/Start system will
be equipped with two batteries. Both the
main and the supplemental batteries
must be disconnected to completely
de-energize the 12 volt electrical
system.
If the negative battery cables are not
isolated properly it can cause a potential
power spike or surge in the system,
resulting in damage to essential elec-
trical components.
CAUTION!
Cleaning the engine compartment with a
high pressure washer is not recommended.
Precautions have been taken to safeguard
all parts and connections however, the
pressures generated by these machines is
such that complete protection against
water ingress cannot be guaranteed.
CAUTION! (Continued)

If you are storing your vehicle for more than
21 days, we recommend that you take the
following steps to minimize the drain on your
vehicle's battery:
Disconnect the negative cable from
battery.
If your vehicle is equipped with Stop/Start
system then disconnect both the main and
supplemental negative battery cables.
Any time you store your vehicle or keep it
out of service (i.e., vacation) for two weeks
or more, run the air conditioning system at
idle for about five minutes in the fresh air
and high blower setting. This will ensure
adequate system lubrication to minimize
the possibility of compressor damage
when the system is started again.
If assistance is needed to disconnect the
battery system, see your authorized dealer.Battery Cable Disconnect
NOTE:
You must isolate the supplemental battery
connection point, as well as the main
battery terminal from the post, as shown in
the image, to fully de-energize both
batteries for storage. If assistance is
needed to disconnect the battery system,
see an authorized dealer.
Do not disconnect the Intelligent Battery
Sensor (IBS), or your Stop/Start system
may not function for up to 24 hours, due
to the IBS being set into learn mode.
BODYWORK
Body And Underbody Maintenance
Cleaning Headlights
Your vehicle is equipped with plastic head -
lights and fog lights that are lighter and less
susceptible to stone breakage than glass
headlights.
Plastic is not as scratch resistant as glass
and therefore different lens cleaning proce -
dures must be followed.
To minimize the possibility of scratching the
lenses and reducing light output, avoid
wiping with a dry cloth. To remove road dirt,
wash with a mild soap solution followed by
rinsing.
Do not use abrasive cleaning components,
solvents, steel wool or other aggressive mate -
rial to clean the lenses.
CAUTION!
If the negative battery cables are not
isolated properly it can cause a potential
power spike or surge in the system,
resulting in damage to essential electrical
components.

Helpful Tips And Common Questions To
Improve Bluetooth® Performance With
Your Uconnect System
Mobile Phone won’t reconnect to system after
pairing:
Set mobile phone to auto-connect or
trusted device in mobile phone
Bluetooth® settings (Blackberry®
devices).
Many mobile phones do not automatically
reconnect after being restarted (hard
reboot). Your mobile phone can still be
connected manually. Close all applica-
tions that may be operating (refer to
mobile phone manufacturer’s instruc-
tions), and follow “Pairing (Wirelessly
Connecting) Your Mobile Phone To The
Uconnect System”.
Perform a factory reset on your mobile
phone. Refer to your mobile phone manu -
facturer or cellular provider for instruc-
tions. This should only be done as a last
resort. Mobile Phone won’t pair to system:

Delete pairing history in mobile phone and
Uconnect system; usually found in
phone’s Bluetooth® connection settings.
Verify you are selecting “Uconnect” in the
discovered Bluetooth® devices on your
mobile phone.
If your vehicle system generates a pin
code the default is 0000.
Perform a hard reset in the mobile phone
by removing the battery (if removable —
see your mobile phone’s owner’s manual).
This should only be done as a last resort.
Mobile Phonebook didn’t download:
Check “Do not ask again”, then accept the
“phonebook download” request on your
mobile phone.
Up to 5,000 contact names with four
numbers per contact will transfer to the
Uconnect 4/4 NAV system phonebook.
Up to 2,000 contact names with six
numbers per contact will transfer to the
Uconnect 3 system phonebook. Can’t make a conference call:
Code-Division Multiple Access (CDMA)
carriers do not support conference calling.
Refer to your mobile phone owner’s
manual for further information.
Making calls while connected to AUX:
Plugging in your mobile phone to AUX
while connected to Bluetooth® will
disable Hands-Free Calling. Do not make
calls while your mobile phone is plugged
into the AUX jack.
