SUGGESTIONS FOR
DRIVING
SAVING FUEL
The following suggestions may help you save fuel
and lower the amount of harmful emissions
released into the atmosphere.
Vehicle Maintenance
Checks and operations should be carried out in
accordance with the Maintenance Plan

Ú
page 199. Tires
Check the tire pressures at least once every four
weeks: if the pressure is too low, consumption
levels increase as resistance to rolling is higher.

NOTE:
Tire pressure that is too high can cause prema
-
ture tire wear, reduced control, etc.
Unnecessary Loads
Do not travel with an overloaded liftgate. The
weight of the vehicle and its arrangement greatly
affect fuel consumption and stability.
Electric Devices
Use electrical systems only for the amount of
time needed. The rear window defroster,
additional headlights, windshield wipers and
heater blower fan require a considerable amount
of energy; increasing the current uptake
increases fuel consumption (by up to +25% when
city driving).
Climate Control System
Using the climate control system will increase
consumption: use standard ventilation when the
temperature outside permits.
Devices For Aerodynamic Control
The use of non-certified devices for aerodynamic
control may adversely affect air drag and
consumption levels.

SAFETY

144

The PBA system is deactivated when the brake
pedal is released.
TRACTION CONTROL SYSTEM (TCS)
The TCS automatically operates in the event of
slipping, loss of grip on wet roads (hydroplaning),
and acceleration on one or both drive wheels on
roads that are slippery, snowy, icy, etc.
Depending on the slipping conditions, two
different control systems are activated:
If the slipping involves both drive wheels, the
system intervenes, reducing the power
transmitted by the engine.
If the slipping only involves one of the drive
wheels, the Brake Limited Differential (BLD)
function is activated, automatically braking the
wheel which is slipping (the behavior of a
self-locking differential is simulated). This will
increase the engine torque transferred to the
wheel which isn't slipping.System Intervention
The intervention of the system is indicated by the
flashing of the ESC Warning Light on the
instrument panel, to inform the driver that the
vehicle stability and grip are critical.
AUXILIARY DRIVING
SYSTEMS
The following auxiliary driving systems may be
available in this vehicle:
Blind Spot Monitoring (BSM) — if equipped
Active Blind Spot Assist (ABSA) — if equipped
Forward Collision Warning Plus (FCW+)
Tire Pressure Monitoring System (TPMS)
The vehicle may also be fitted with the following
driving assistance systems:
Driver Attention Assist (DAA)
Lane Departure Warning (LDW)
Lane Keeping Assist (LKA)
Highway Assist System (HAS)
Traffic Jam Assist (TJA)
Adaptive Cruise Control (ACC)
Intelligent Speed Control (ISC)
Traffic Sign Recognition (TSR)
For the operation of the DAA, LDW, LKA, HAS, TJA,
ACC, ISC, or TSR systems, see

Ú
page 86.

NOTE:
When driving on two-way roads where there is no
lane dividing center line (e.g. on unpaved roads),
the use of the ABSA, HAS, TJA, and LKA systems is strongly discouraged as the system could
detect the entire road as single-lane dividing
lines.

NOTE:
The driving assistance systems are designed to
aid in driving the car. The driver must always
maintain a sufficient level of attention to the
traffic and road conditions and control the
trajectory of the car.
BLIND SPOT MONITORING (BSM)
S
YSTEM — IF EQUIPPED
The BSM system uses radar sensors, located in
the rear fascia/bumper, to detect the presence of
other vehicles in the rear side blind spots of your
vehicle.
Rear Sensor Location
The system warns the driver about the presence
of other vehicles in the detection area by illumi -
nating the warning light located within the door
mirror on the side in which the other vehicle was
detected. If equipped, an audible chime will also
be heard to alert the driver (if option is selected
within the radio system).
WARNING!
The Panic Brake Assist (PBA) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction
afforded by prevailing road conditions.
PBA cannot prevent collisions, including
those resulting from excessive speed in
turns, driving on very slippery surfaces, or
hydroplaning. The capabilities of a
PBA-equipped vehicle must never be exploited
in a reckless or dangerous manner, which
could jeopardize the user's safety or the
safety of others.

TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The vehicle is equipped with a Tire Pressure
Monitoring System (TPMS) that sends the
inflation pressure information of each tire to the
control unit, and will signal the driver in the event
of insufficient tire pressure.
The TPMS uses wireless technology with wheel
rim mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each wheel
as part of the valve stem, transmit tire pressure
readings to the receiver module.
Tire pressure will vary with temperature by
approximately 1 psi (7 kPa) for every 12°F
(6.5°C). This means that when the outside
temperature decreases, the tire pressure will also
decrease. Tire pressure should always be set
based on cold inflation tire pressure. This 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 a three hour
period. The cold tire inflation pressure must not
exceed the maximum inflation pressure molded
into the tire sidewall. The tire pressure will also
increase as the vehicle is driven. This is normal,
and there should be no adjustment for this
increased pressure.
See

Ú
page 224 for information on how to
properly inflate the vehicle’s tires.
The TPMS will signal the driver if pressure falls
below the warning limit for any reason, including
the effects of low temperature and normal loss of
pressure from the tire.
The TPMS will stop indicating insufficient tire
pressure when pressure is equal to or greater than
the prescribed cold inflation level. Therefore, if
insufficient tire pressure is indicated by the ( )
warning light displaying in the instrument cluster,
increase the inflation pressure up to the
prescribed cold inflation value.

The system will automatically update, and the
TPMS Warning Light will turn off once the system
receives the updated tire pressures. The vehicle
may need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to
receive this information.

NOTE:
The TPMS cannot indicate sudden tire pressure
drops (e.g. if a tire bursts). In this case, proceed
with caution and avoid abrupt steering.
Operating Example
For example, your vehicle may have a
recommended cold (parked for more than three
hours) placard pressure of 33 psi (227 kPa). If the
ambient temperature is 68°F (20°C), and the
measured tire pressure is 28 psi (193 kPa), a
temperature drop to 20°F (-7°C) will decrease
the tire pressure to approximately 24 psi
(165 kPa). This tire pressure is low enough to turn
on the Tire Pressure Monitoring Warning Light.
Driving the vehicle may cause the tire pressure to
rise to approximately 28 psi (193 kPa), but the
TPMS Warning Light will still be on. In this
situation, the TPMS Warning Light will turn off
only after the tires are inflated to the vehicle’s
recommended cold placard pressure value.
WARNING!
The system has not been designed to
prevent impacts and cannot detect possible
conditions leading to an accident in
advance. Failure to take into account this
warning may lead to serious or fatal injuries.
The system may activate, assessing the
trajectory of the vehicle, for the presence of
reflecting metal objects different from other
vehicles, such as safety barriers, road signs,
barriers before parking lots, tollgates, level
crossings, gates, railways, objects near road
constructions sites or higher than the vehicle
(e.g. a fly-over). In the same way, the system
may intervene inside multi-story parking lots
or tunnels, or due to a glare on the road
surface. These possible activations are a
consequence of the real driving scenario
coverage by the system and must not be
regarded as faults.
The system has been designed for road use
only. If the vehicle is driven on a track, the
system must be deactivated to avoid
unnecessary warnings. Automatic deacti
-
vation is signaled by the dedicated warning
light/symbol switching on in the instrument
panel

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

157

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.

IN CASE OF EMERGENCY

188

14. Raise the vehicle by turning the jack screwclockwise, using the swivel wrench. Raise the
vehicle only until the tire just clears the
surface and enough clearance is obtained to
install the compact spare tire. Minimum tire
lift provides maximum stability.
15. Remove the five wheel bolts and take the wheel off.
16. Make sure the contact surfaces between compact spare tire and hub are clean so that
the fastening bolts will not come loose.
17. Fit the compact spare tire by inserting the first wheel bolt for two threads into the hole
closest to the valve.
18. Take the wheel wrench and tighten the wheel bolts.
19. Inflate the compact spare tire by removing the cap from its inflation valve and screwing
on the compressor inflation hose fitting. 20. Make sure that the switch on the compressor
is in the O (off) position, open the liftgate and
insert the plug into the power socket in the
cargo area, or on the center console and
start the engine. Place the on/off switch in
the I (on) position.
Attaching Compressor To Tire
21. Inflate the compact spare tire to a pressure of 43.5 psi (3 bar).

NOTE:
If spare tire is overinflated, be sure to lower the
psi in the tire to the recommended amount by
using the deflation button on the air compressor.
22. Operate the wheel wrench on the jack to lower the vehicle.
23. Remove the jack. 24. Use the wheel wrench to fully tighten the
bolts, passing alternately from one bolt to the
diagonally opposite one.
To obtain a more accurate reading, it is advisable
to check the pressure of the compact spare tire
on the pressure gauge with the compressor off.

NOTE:
Do not stow the deflated tire in the compact
spare tire location.
The compressor was designed for inflating the
compact spare tire. Do not use it for inflating
mattresses, rafts, etc.

NOTE:
Spare tires are intended for temporary use only.
Have the full-sized tire repaired or replaced, as
soon as possible.
WARNING!
Raising the vehicle higher than necessary can
make the vehicle less stable. It could slip off
the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
CAUTION!
Be sure to mount the spare tire with the valve
stem facing outward. The vehicle could be
damaged if the spare tire is mounted
incorrectly.

TIRE SERVICE KIT —
IF EQUIPPED
DESCRIPTION
If a tire is punctured, you can make an emergency
repair using the Tire Service Kit located in the rear
storage area under the load platform.
1. Stop the vehicle in a position where you can repair the tire safely. You should be as far as
possible from the side of the road, and in a
position that is not dangerous for oncoming
traffic. Turn on the Hazard Warning Flashers,
remove the safety triangle from the luggage
compartment, and place it at a suitable
distance from the vehicle to make other
drivers aware of your presence.
2. Verify that the valve stem (on the wheel with the deflated tire) is in a position that is near
to the ground. This will allow the tire repair kit
hoses to reach the valve stem and keep the
tire service kit flat on the ground.
3. Place the gear selector in PARK (P).
4. Apply the electric park brake and turn the engine OFF. To access the Tire Service Kit, open the liftgate
and lift the load floor.
