Tire Inflation Pressures
The proper cold tire inflation pressure is
listed on the driver's side B-Pillar or rear edge
of the driver's side door.
At least once a month:
• Check and adjust tire pressure with a goodquality pocket-type pressure gauge. Do not
make a visual judgement when determining
proper inflation. Tires may look properly
inflated even when they are under-inflated.
• Inspect tires for signs of tire wear or visible damage.
CAUTION!
After inspecting or adjusting the tire pres-
sure, always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could dam-
age the valve stem.
Inflation pressures specified on the placard
are always “cold tire inflation pressure”. Cold
tire inflation pressure is defined as the tire
pressure after the vehicle has not been driven
for at least three hours, or driven less than 1 mile (1.6 km) after sitting for a minimum of
three hours. The cold tire inflation pressure
must not exceed the maximum inflation pres-
sure molded into the tire sidewall.
Check tire pressures more often if subject to
a wide range of outdoor temperatures, as tire
pressures vary with temperature changes.
Tire pressures change by approximately 1 psi
(7 kPa) per 12°F (7°C) of air temperature
change. Keep this in mind when checking
tire pressure inside a garage, especially in the
Winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature = 32°F
(0°C) then the cold tire inflation pressure
should be increased by 3 psi (21 kPa), which
equals 1 psi (7 kPa) for every 12°F (7°C) for
this outside temperature condition.
Tire pressure may increase from 2 to 6 psi
(13 to 40 kPa) during operation. DO NOT
reduce this normal pressure build up or your
tire pressure will be too low.
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe
speeds and within posted speed limits.
Where speed limits or conditions are such
that the vehicle can be driven at high speeds,
maintaining correct tire inflation pressure is
very important. Increased tire pressure and
reduced vehicle loading may be required for
high-speed vehicle operation. Refer to your
authorized tire dealer or original equipment
vehicle dealer for recommended safe operat-
ing speeds, loading and cold tire inflation
pressures.
WARNING!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to
fail. You could have a serious collision. Do
not drive a vehicle loaded to the maximum
capacity at continuous speeds above
75 mph (120 km/h).SERVICING AND MAINTENANCE

WARNING!
• ALWAYS obey traffic laws and pay atten-tion to the road. Some features are lim-
ited while the vehicle is in motion. Some
services, including SOS, will NOT work
without a subscription and an operable
network connection.
• Ignoring the rearview mirror light could
mean you may not have SOS Call service
if needed. If the rearview mirror light is
illuminated, have an authorized dealer
service the SOS Call system immedi-
ately.
• The Occupant Restraint Controller
(ORC) turns on the Air Bag Warning
Light on the instrument panel if a mal-
function is detected in any part of the
airbag system. If the Air Bag Warning
Light is illuminated, the air bag system
may not be working properly and the
SOS Call system may not send a signal to
a SOS Call operator if an air bag is
deployed. If the Air Bag Warning Light is
illuminated, have an authorized dealer
service your vehicle immediately.
WARNING!
• If anyone in the vehicle could be indanger (e.g., fire or smoke is visible,
dangerous road conditions or location),
do not wait for voice contact from a SOS
Call operator. All occupants should exit
the vehicle immediately and move to a
safe location.
• The SOS Call system is embedded into
the vehicle’s electrical system. Do not
add aftermarket electrical equipment to
the vehicle’s electrical system. This may
prevent your vehicle from sending a sig-
nal to initiate an emergency call. To
avoid interference that can cause the
SOS Call system to fail, never add after-
market equipment (e.g., two-way mobile
radio, CB radio, data recorder, etc.) to
your vehicle’s electrical system or
modify the antennas on your vehicle.
• IF YOUR VEHICLE LOSES BATTERY
POWER FOR ANY REASON (INCLUD-
ING DURING OR AFTER AN ACCI-
DENT), the Uconnect features, apps,
and SiriusXM Guardian services, among
others, will not operate. NOTE:
Your vehicle may be transmitting data as
authorized by the subscriber.

ASSIST Call (4C NAV) —
The rearview mirror
contains an ASSIST button, allowing you to
speak to a call center agent for support:
• Roadside Assistance Call
— If you get a
flat tire, or need a tow, you’ll be con-
nected to someone who can help any-
time. Additional fees may apply. Addi-
tional information in this section.

TIPS CONTROLS AND GENERAL
INFORMATION
Steering Wheel Audio Controls
The steering wheel audio controls are located
on the rear surface of the steering wheel.
Reception Conditions
Reception conditions change constantly
while driving. Reception may be interfered
with by the presence of mountains, buildings
or bridges, especially when you are far away
from the broadcaster.The volume may be increased when receiving
traffic alerts and news.
Care And Maintenance
Observe the following precautions to ensure
the system is fully operational:
• The display lens should not come into con-
tact with pointed or rigid objects which
could damage its surface; use a soft, dry
anti-static cloth to clean and do not press.
• Never use alcohol, gas and derivatives to clean the display lens.
• Prevent any liquid from entering the sys- tem: this could damage it beyond repair.
Anti-Theft Protection
The system is equipped with an anti-theft
protection system based on the exchange of
information with the electronic control unit
(Body Computer) on the vehicle.
This guarantees maximum safety and pre-
vents the secret code from being entered
after the power supply has been discon-
nected. If the check has a positive outcome, the
system will start to operate, whereas if the
comparison codes are not the same or if the
electronic control unit (Body Computer) is
replaced, the system will ask the user to enter
the secret code. See an authorized dealer for
further information.
