364 STARTING AND OPERATING

Driving Through Water

Driving through water more than a few inches/centimeters

deep will require extra caution to ensure safety and prevent

damage to your vehicle.
Flowing/Rising Water

Shallow Standing Water

Although your vehicle is capable of driving through shallow

standing water, consider the following Cautions and Warn-

ings before doing so.

WARNING!

Do not drive on or across a road or path where water is

flowing and/or rising (as in storm run-off). Flowing

water can wear away the road or path's surface and cause

your vehicle to sink into deeper water. Furthermore,

flowing and/or rising water can carry your vehicle away

swiftly. Failure to follow this warning may result in

injuries that are serious or fatal to you, your passengers,

and others around you.

WARNING!

• Driving through standing water limits your vehicle’s

traction capabilities. Do not exceed 5 mph (8 km/h)

when driving through standing water.

• Driving through standing water limits your vehicle’s

braking capabilities, which increases stopping

distances. Therefore, after driving through standing

water, drive slowly and lightly press on the brake pedal

several times to dry the brakes.

• Failure to follow these warnings may result in injuries

that are serious or fatal to you, your passengers, and

others around you.

STARTING AND OPERATING

365

CAUTION!

• Always check the depth of the standing water before

driving through it. Never drive through standing water

that is deeper than the bottom of the tire rims mounted

on the vehicle.

• Determine the condition of the road or the path that is

under water and if there are any obstacles in the way

before driving through the standing water.

• Do not exceed 5 mph (8 km/h) when driving through

standing water. This will minimize wave effects.

• Driving through standing water may cause damage to

your vehicle’s drivetrain components. Always inspect

your vehicle’s fluids (i.e., engine oil, transmission, axle,

etc.) for signs of contamination (i.e., fluid that is milky

or foamy in appearance) after driving through standing

water. Do not continue to operate the vehicle if any

fluid appears contaminated, as this may result in

further damage. Such damage is not covered by the

New Vehicle Limited Warranty.

• Getting water inside your vehicle’s engine can cause it

to lock up and stall out, and cause serious internal

damage to the engine. Such damage is not covered by

the New Vehicle Limited Warranty.

IN CASE OF EMERGENCY

HAZARD WARNING FLASHERS

The Hazard Warning switch is located on the upper

switch bank just below the radio.

NOTE:

If your vehicle is equipped with a 12–inch Uconnect display,

the Hazard Warning switch is located above the display.
Push the switch to turn on the Hazard Warning flasher.

When the switch is activated, all directional turn signals will

flash on and off to warn oncoming traffic of an emergency.

Push the switch a second time to turn off the Hazard

Warning flashers.
This is an emergency warning system and it should not be

used when the vehicle is in motion. Use it when your vehicle

is disabled and it is creating a safety hazard for other motor-

ists.
When you must leave the vehicle to seek assistance, the

Hazard Warning flashers will continue to operate even

though the ignition is placed in the OFF position.

NOTE:

With extended use the Hazard Warning flashers may wear

down your battery.

ASSIST AND SOS SYSTEM — IF EQUIPPED

Assist And SOS Buttons

1 — ASSIST Button

2 — SOS Button

IN CASE OF EMERGENCY

367

If equipped, the overhead console contains an ASSIST and a

SOS button.

NOTE:
• Your vehicle may be transmitting data as authorized by

the subscriber.

• The SOS and ASSIST buttons will only function if you are

connected to an operable LTE (voice/data) or 4G (data)

network. Other Uconnect services will only be operable if

your SiriusXM Guardian™ service is active and you are

connected to an operable LTE (voice/data) or 4G (data)

network.

ASSIST Call
The ASSIST Button is used to automatically connect you to

any one of the following support centers:
• Roadside Assistance – If you get a flat tire, or need a tow,

just push the ASSIST button and you’ll be connected to

someone who can help. Roadside Assistance will know

what vehicle you’re driving and its location. Additional

fees may apply for roadside assistance.

• SiriusXM Guardian™ Customer Care – In-vehicle support

for SiriusXM Guardian™.

• Vehicle Customer Care – Total support for all other vehicle

issues.

SOS Call
1. Push the SOS Call button on the overhead console.
NOTE:

In case the SOS Call button is pushed in error, there will be a

ten second delay before the SOS Call system initiates a call to

a SOS operator. To cancel the SOS Call connection, push the

SOS call button on the overhead console or press the cancel-

lation button on the Device Screen. Termination of the SOS

Call will turn off the green LED light on the overhead

console.

WARNING!

ALWAYS obey traffic laws and pay attention to the road.

ALWAYS drive safely with your hands on the steering

wheel. You have full responsibility and assume all risks

related to the use of the features and applications in this

vehicle. Only use the features and applications when it is

safe to do so. Failure to do so may result in an accident

involving serious injury or death.

368 IN CASE OF EMERGENCY

(Continued)

2. The LED light located between the ASSIST and SOS

buttons on the overhead console will turn green once a

connection to a SOS operator has been made.

3. Once a connection between the vehicle and a SOS oper-

ator is made, the SOS Call system may transmit the

following important vehicle information to a SOS oper-

ator:
• Indication that the occupant placed a SOS Call.

• The vehicle brand.

• The last known GPS coordinates of the vehicle.

4. You should be able to speak with the SOS operator

through the vehicle audio system to determine if addi-

tional help is needed.

NOTE:

• Your vehicle may be transmitting data as authorized by

the subscriber.

• Once a connection is made between the vehicle’s SOS

Call system and the SOS operator, the SOS operator

may be able to open a voice connection with the vehicle

to determine if additional help is needed. Once the SOS

operator opens a voice connection with the vehicle’s

SOS Call system, the operator should be able to speak

with you or other vehicle occupants and hear sounds

occurring in the vehicle. The vehicle’s SOS Call system

will attempt to remain connected with the SOS operator

until the SOS operator terminates the connection.

5. The SOS operator may attempt to contact appropriate

emergency responders and provide them with important

vehicle information and GPS coordinates.

WARNING!

ALWAYS obey traffic laws and pay attention to the road.

ALWAYS drive safely with your hands on the steering

wheel. You have full responsibility and assume all risks

related to the use of the features and applications in this

SOS Call System Limitations
Vehicles sold in Mexico DO NOT have SOS Call system

capabilities.
SOS or other emergency line operators in Mexico may not

answer or respond to SOS system calls.
If the SOS Call system detects a malfunction, any of the

following may occur at the time the malfunction is detected,

and at the beginning of each ignition cycle:
• The overhead console light located between the ASSIST

and SOS buttons will continuously be illuminated red.

• The Device Screen will display the following message:

“Vehicle device requires service. Please contact your

dealer.”

• An In-Vehicle Audio message will state “Vehicle device

requires service. Please contact your dealer.”

• Never place anything on or near the vehicle’s operable

network and GPS antennas. You could prevent oper-

able network and GPS signal reception, which can

prevent your vehicle from placing an emergency call.

An operable network and GPS signal reception is

required for the SOS Call system to function properly.

• 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 signal to initiate

an emergency call. To avoid interference that can cause

the SOS Call system to fail, never add aftermarket

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 (INCLUDING DURING OR AFTER AN

ACCIDENT), THE UCONNECT FEATURES, APPS

AND SERVICES, AMONG OTHERS, WILL NOT

OPERATE.

WARNING! (Continued)

• Modifications to any part of the SOS Call system could

cause the air bag system to fail when you need it. You

could be injured if the air bag system is not there to

help protect you.

WARNING! (Continued)

6

370 IN CASE OF EMERGENCY

Even if the SOS Call system is fully functional, factors

beyond FCA US LLC’s control may prevent or stop the SOS

Call system operation. These include, but are not limited to,

the following factors:
• Delayed accessories mode is active.
• The ignition is in the OFF position.
• The vehicle’s electrical systems are not intact.
• The SOS Call system software and/or hardware are

damaged during a crash.

• The vehicle battery loses power or becomes disconnected

during a vehicle crash.

• LTE (voice/data) or 4G (data) network and/or Global

Positioning Satellite signals are unavailable or obstructed.

• Equipment malfunction at the SOS operator facility.
• Operator error by the SOS operator.
• LTE (voice/data) or 4G (data) network congestion.
• Weather.
• Buildings, structures, geographic terrain, or tunnels.

WARNING!

• Ignoring the overhead console light could mean you

will not have SOS Call services. If the overhead console

light is illuminated, have your authorized dealer

service the SOS Call system immediately.

• The Occupant Restraint Control module turns on the

air bag Warning Light on the instrument panel if a

malfunction in any part of the system is detected. If the

Air Bag Warning Light is illuminated, have your autho-

rized dealer service the Occupant Restraint Control

system immediately.

WARNING!

ALWAYS obey traffic laws and pay attention to the road.

ALWAYS drive safely with your hands on the steering

wheel. You have full responsibility and assume all risks

related to the use of the features and applications in this

vehicle. Only use the features and applications when it is
