HILL DESCENT CONTROL (HDC)
S
YSTEM — IF EQUIPPED
The HDC function is an integral part of the
Electronic Stability Control (ESC) system, keeping
the vehicle at a constant speed while descending
a hill by actively controlling the brakes.
HDC aims to create vehicle stability and safer
driving in various situations, including poor grip
conditions and steep descents.
The system has three different modes:
Off: the system is deactivated
Enabled: the system is enabled and ready
to intervene when the activation conditions
are met
Active: the system actively controls the
vehicle speed Enabling The System
To enable the system, push the HDC switch
located on the steering wheel.
HDC Switch
The system is enabled if the car speed is below
20 mph (30 km/h). The system stays enabled
until the car speed reaches 37 mph (60 km/h),
the system is disabled at speeds above 37 mph
(60 km/h).
Activation of the HDC system is indicated by the
white icon appearing in the instrument
cluster display.
HDC Symbol Activation Of The System
Once enabled, the HDC system will activate
automatically if the vehicle is driven on a downhill
slope with sufficient gradient, greater than 8%.
The speed set for the HDC system can be
adjusted using the SET switch located on the
steering wheel.
HDC Speed SET Switch
Once the desired speed has been reached,
release the SET switch and the HDC system will
maintain the set speed. After set speed is
established, the HDC system will automatically
brake to keep the vehicle at the set speed if the
accelerator pedal is released and the vehicle gets
close to the set speed.
It is possible to reduce the set speed with the
brake pedal. When the pedal is released, the
system will adjust the set speed to the new
current speed.
Vehicle modifications, or failure to properly
maintain your vehicle, may change the
handling characteristics of your vehicle, and
may negatively affect the performance of the
ESC system. Changes to the steering system,
suspension, braking system, tire type and
size or wheel size may adversely affect ESC
performance. Improperly inflated and
unevenly worn tires may also degrade ESC
performance. Any vehicle modification or
poor vehicle maintenance that reduces the
effectiveness of the ESC system can
increase the risk of loss of vehicle control,
vehicle rollover, personal injury and death.

Insufficient Tire Pressure Indication
If an insufficient pressure value is detected on
one or more tires, the warning light in the
instrument cluster will display alongside the
dedicated messages, the system will highlight the
tire or tires with insufficient pressure graphically,
and an acoustic signal will be emitted.In this case, stop the vehicle, check the inflation
pressure of each tire, and inflate the necessary
tire or tires to the correct cold inflation pressure
value, shown on the display or in the dedicated
TPMS menu.
TPMS Temporarily Disabled:
TPMS Check Message
When a system fault is detected, the TPMS
Warning Light will flash on and off for 75 seconds,
and then remain on solid. The system fault will
also sound a chime. If the ignition is cycled, this
sequence will repeat, provided that the system
fault still exists. The TPMS Warning Light will turn
off when the fault condition no longer exists. A
system fault can occur due to any of the following:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPMS sensors.
Installing some form of aftermarket window
tinting that affects radio wave signals.
Packed snow or ice around the wheels or
wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with
TPMS sensors.
After the punctured tire has been repaired with
the original tire sealant contained in the tire kit,
the previous condition must be restored so that
the warning light is off during normal driving.
TPMS Deactivation
The TPMS can be deactivated by replacing all
four wheel and tire assemblies (road tires) with
wheel and tire assemblies that do not have TPMS
sensors, such as when installing winter wheel
and tire assemblies on your vehicle. To deactivate the TPMS, first replace all four
wheel and tire assemblies (road tires) with tires
not equipped with Tire Pressure Monitoring
System (TPMS) sensors. Then, drive the vehicle
for 20 minutes above 15 mph (24 km/h). The
TPMS will chime, the TPMS Warning Light will
flash on and off for 75 seconds and then remain
on. The instrument cluster will display the
“SERVICE TPM SYSTEM” message and then
display dashes (--) in place of the pressure values.
Beginning with the next ignition switch cycle, the
TPMS will no longer chime or display the
“SERVICE TPM SYSTEM” message in the
instrument cluster. Instead, dashes (--) will
remain in place of the pressure values.
To reactivate the TPMS, replace all four wheel
and tire assemblies (road tires) with tires
equipped with TPMS sensors. Then, drive the
vehicle for up to 20 minutes above 15 mph
(24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for 75 seconds
and then turn off. The instrument cluster will
display the “SERVICE TPM SYSTEM” message
and then display pressure values in place of the
dashes. On the next ignition switch cycle the
“SERVICE TPM SYSTEM” message will no longer
be displayed, as long as no system fault exists.

NOTE:

The TPMS is not intended to replace normal
tire care and maintenance, or to provide
warning of a tire failure or condition.
The TPMS should not be used as a tire
pressure gauge while adjusting your tire
pressure.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS
pressures and warning have been
established for the tire size equipped on your
vehicle. Undesirable system operation or
sensor damage may result when using
replacement equipment that is not of the
same size, type, and/or style. The TPMS
sensor is not designed for use on
aftermarket wheels and may contribute to a
poor overall system performance or sensor
damage. Customers are encouraged to use
Original Equipment Manufacturer (OEM)
wheels to ensure proper TPMS feature
operation.
Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended
that you take your vehicle to an authorized
dealer to have your sensor function checked.
After inspecting or adjusting the tire pressure
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the TPMS
sensor.
23_GU_OM_EN_USC_t.book Page 156

Driving on a significantly underinflated tire will
cause the tire to overheat, and can lead to tire
failure. Underinflation also reduces fuel
efficiency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsi-
bility to maintain correct tire pressure using an
accurate tire pressure gauge, even if underin -
flation has not reached the level to trigger
illumination of the TPMS Warning Light.
Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the actual
tire pressure in the tire

OCCUPANT RESTRAINT
SYSTEMS
Some of the most important safety features in
your vehicle are the restraint systems:
OCCUPANT RESTRAINT SYSTEMS
F
EATURES
Seat Belt Systems
Supplemental Restraint Systems (SRS)
Air Bags
Child Restraints
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on others.
If you are not sure, ask an authorized dealer.
IMPORTANT SAFETY PRECAUTIONS
Please pay close attention to the information in
this section. It tells you how to use your restraint
system properly, to keep you and your
passengers as safe as possible.
Here are some simple steps you can take to
minimize the risk of harm from a deploying
air bag:
1. Children 12 years old and under should always ride buckled up in the rear seat of a
vehicle with a rear seat.
2. A child who is not big enough to wear the vehicle seat belt properly must be secured in
the appropriate child restraint or belt-posi -
tioning booster seat in a rear seating position

Ú
page 170.
3. If a child from 2 to 12 years old (not in a rear-facing child restraint) must ride in the
front passenger seat, move the seat as far
back as possible and use the proper child
restraint

Ú
page 170.
4. Never allow children to slide the shoulder belt behind them or under their arm.
5. You should read the instructions provided with your child restraint to make sure that you
are using it properly.
6. All occupants should always wear their lap and shoulder belts properly. 7. The driver and front passenger seats should
be moved back as far as practical to allow the
front air bags room to inflate.
8. Do not lean against the door or window. If your vehicle has side air bags, and deploy -
ment occurs, the side air bags will inflate
forcefully into the space between occupants
and the door and occupants could be injured.
9. If the air bag system in this vehicle needs to be modified to accommodate a disabled
person, see

Ú
page 255 for customer
service contact information.
WARNING!
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious
injury to a child 12 years or younger,
including a child in a rear-facing child
restraint.
Never install a rear-facing child restraint in
the front seat of a vehicle. Only use a
rear-facing child restraint in the rear seat.
If the vehicle does not have a rear seat, do
not transport a rear-facing child restraint in
that vehicle.

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and
uneven wear patterns. Check for stones, nails,
glass, or other objects lodged in the tread or
sidewall. Inspect the tread for cuts and cracks.
Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the
tires (including spare) for proper cold inflation
pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel, or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
EXHAUST GAS
The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
Whenever a change is noticed in the sound of the
exhaust system, when exhaust fumes can be
detected inside the vehicle, or when the
underside or rear of the vehicle is damaged, have
a competent mechanic inspect the complete
exhaust system and adjacent body areas for
broken, damaged, deteriorated, or mispositioned parts. Open seams or loose connections could
permit exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust
system each time the vehicle is raised for
lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
WARNING!

Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (CO), follow these safety tips:

Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/
liftgate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to
prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in a
closed area, such as a garage, and never sit
in a parked vehicle with the engine running
for an extended period. If the vehicle is
stopped in an open area with the engine
running for more than a short period, adjust
the ventilation system to force fresh, outside
air into the vehicle.
Guard against carbon monoxide with proper
maintenance. Have the exhaust system
inspected every time the vehicle is raised.
Have any abnormal conditions repaired
promptly. Until repaired, drive with all side
windows fully open.
When exiting the vehicle, always make sure
the ignition is in the off position, remove the
key fob from the vehicle, and lock your
vehicle.

If the vehicle battery connection fails due to a
collision or accident, the system can support an
SOS Emergency Call for a limited period of time. If
the battery is disconnected for service, the
system turns off. In this case, it will be possible to
make an SOS Emergency Call only when the
battery is reconnected to the vehicle’s electrical
system.
System Requirements
Vehicle must have an operable 4G network
connection.
Vehicle must be powered with a properly
functioning electrical system.
The ignition must be in the RUN or ACC
position.
Frequently Asked Questions:
What happens if I accidentally push the SOS
Emergency Call Button?
You have 10 seconds
after pushing the emergency button to cancel the
call. To cancel the call, push the button again.
What type of information is sent when I make an
SOS Emergency Call from my vehicle? Certain
vehicle information, such as the VIN, is
transmitted along with last known GPS location.
Also note that emergency service operators may
record conversations and sounds within your
vehicle once a connection is made, and by using
the service you consent to having this information
shared.
When can I use the SOS Emergency Call
button? You can ONLY use the SOS
Emergency Call button to make a call if
you or someone else needs emergency
assistance.
WARNING!
Never place anything on or near the vehicle’s
4G and GPS aerials. You could prevent
4G and GPS signal reception, which can
prevent your vehicle from placing an
emergency call. An operable 4G network
connection and a GPS signal is required
for the SOS-Emergency Call system to
function properly.
Do not add any 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-Emergency 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
AND SYSTEM LOSES BATTERY POWER FOR
ANY REASON (INCLUDING DURING OR AFTER
AN ACCIDENT) THE SOS FEATURES, APPS
AND SERVICES AMONG OTHERS WILL
NOT OPERATE.
The Occupant Restraint Controller (ORC)
turns on the air bag warning light in the
instrument cluster if a malfunction in any
part of the air bag system is detected. If the
air bag warning light is illuminated, the air
bag system may not be working properly and
the SOS-Emergency Call system may not be
able to send a signal to an emergency
service operator. If the air bag warning light
is illuminated, contact the Service Network
to have the air bag system checked
immediately.
Ignoring the LED on the SOS-Emergency Call
button could mean you will not have
emergency call services if needed. If the LED
on SOS-Emergency Call button is illuminated
red, contact the Service Network to have the
emergency call system checked
immediately.
