Refer to local laws for maximum trailer towing speeds.

NOTE:

The trailer tongue weight must be considered as part of the combined weight of occupants and cargo, and should never exceed the weight refer -
enced on the Tire and Loading Information placard.
CAUTION!
Always load a trailer with 60% of the weight
in the front of the trailer. This places 10% of
the GTW on the tow hitch of your vehicle.
Loads balanced over the wheels or heavier
in the rear can cause the trailer to sway
severely side to side which will cause loss
of control of the vehicle and trailer. Failure
to load trailers heavier in front is the cause
of many trailer collisions.

(Continued)
Consider the following items when computing
the weight on the rear axle of the vehicle:
The tongue weight of the trailer.
The weight of any other type of cargo or
equipment put in or on your vehicle.
The weight of the driver and all passengers.

NOTE:

Remember that everything put into or on the
trailer adds to the load on your vehicle. Also,
additional factory-installed options or
dealer-installed options must be considered
as part of the total load on your vehicle. Refer
to the “Tire And Loading Information” placard
for the maximum combined weight of occu -
pants and cargo for your vehicle.
Towing Requirements
To promote proper break-in of your new
vehicle drivetrain components, the following
guidelines are recommended:
Towing Requirements — Tires
Do not attempt to tow a trailer while using a
compact spare tire.
Do not drive more than 50 mph (80 km/h)
when towing while using a full size spare
tire.
Proper tire inflation pressures are essential
to the safe and satisfactory operation of
your vehicle.
Check the trailer tires for proper tire infla -
tion pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer.
Replacing tires with a higher load carrying
capacity will not increase the vehicle's
GVWR and GAWR limits.
For proper tire inflation procedures

Ú
page 233.
WARNING!
Improper towing can lead to a collision.
Follow these guidelines to make your trailer
towing as safe as possible:
Make certain that the load is secured in
the trailer and that it will not shift during
travel. When trailering cargo that is not
fully secured, dynamic load shifts can
occur that may be difficult for the driver to
control. You could lose control of your
vehicle and have a collision.
When hauling cargo, or towing a trailer, do
not overload your vehicle or trailer. Over -
loading can cause a loss of control, poor
performance, or damage to brakes, axle,
engine, transmission, steering, suspen -
sion, chassis structure, or tires.
Safety chains must always be used
between your vehicle and trailer. Always
connect the chains to the frame or hook
retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow
enough slack for turning corners.
Vehicles with trailers should not be parked
on a grade. When parking, apply the
parking brake on the tow vehicle. Put the
tow vehicle transmission in PARK. Always
block or "chock" the trailer wheels.
GCWR must not be exceeded.
Total weight must be distributed between
the tow vehicle and the trailer such that
the following four ratings are not
exceeded:
• GVWR
• GTW
• GAWR
• Tongue weight rating for the trailer
hitch utilized.
WARNING! (Continued) CAUTION!
Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is
driven. The engine, axle or other parts
could be damaged.
Then, during the first 500 miles (805 km)
that a trailer is towed, do not drive over
50 mph (80 km/h) and do not make
starts at full throttle. This helps the engine
and other parts of the vehicle wear in at
the heavier loads.

Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake
system or vacuum system of your vehicle
with that of the trailer. This could cause
inadequate braking and possible personal
injury.
An electronically actuated trailer brake
controller is required when towing a trailer
with electronically actuated brakes. When
towing a trailer equipped with a hydraulic
surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers
over 1,000 lbs (453 kg) and required for
trailers in excess of 2,000 lbs (907 kg).
Towing Requirements — Trailer Lights And
Wiring
Whenever you pull a trailer, regardless of the
trailer size, stoplights and turn signals on the
trailer are required for motoring safety.
The Trailer Tow Package may include a four-
and seven-pin wiring harness. Use a factory
approved trailer harness and connector.

NOTE:

Do not cut or splice wiring into the vehicle’s
wiring harness.
The electrical connections are all complete to
the vehicle but you must mate the harness to
a trailer connector. Refer to the following illus -
trations.

NOTE:

Disconnect trailer wiring connector from the
vehicle before launching a boat (or any
other device plugged into vehicle’s elec -
trical connect) into water.
Be sure to reconnect once clear from water
area. Four-Pin Connector
Seven-Pin Connector
WARNING!
Do not connect trailer brakes to your
vehicle's hydraulic brake lines. It can over -
load your brake system and cause it to
fail. You might not have brakes when you
need them and could have an accident.
Towing any trailer will increase your stop -
ping distance. When towing, you should
allow for additional space between your
vehicle and the vehicle in front of you.
Failure to do so could result in an acci -
dent.
CAUTION!
If the trailer weighs more than 1,000 lbs
(453 kg) loaded, it should have its own
brakes and they should be of adequate
capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake
pedal effort, and longer stopping distances.

Towing Tips
Before setting out on a trip, practice turning,
stopping, and backing up the trailer in an area
located away from heavy traffic.
Automatic Transmission
Select the DRIVE range when towing. The
transmission controls include a drive strategy
to avoid frequent shifting when towing.
However, if frequent shifting does occur while
in DRIVE, you can use the AutoStick shift
control to manually select a lower gear.

NOTE:

Using a lower gear while operating the vehicle
under heavy loading conditions will improve
performance and extend transmission life by
reducing excessive shifting and heat build-up.
This action will also provide better engine
braking.
Cruise Control — If Equipped
Do not use on hilly terrain or with heavy
loads.
When using the Cruise Control, if you expe-
rience speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed.
Use Cruise Control in flat terrain and with
light loads to maximize fuel efficiency.
Installing The Receiver
To properly install the receiver, follow the
directions below:
1. Retrieve the receiver from the luggage compartment.
2. Push the receiver into the trailer hitch, and secure by inserting the locking pin into the
trailer hitch.
3. Insert the safety split ring into the hole on the locking pin.

NOTE:

Ensure that the locking pin is removed from
the trailer hitch before installing the receiver.

SUGGESTIONS FOR DRIVING
Saving Fuel
Below are some suggestions which 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 208.
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
premature 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, addi
-
tional 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 aerody -
namic control may adversely affect air drag
and consumption levels.
Driving Style
Starting
Do not warm up the engine at low or high revs
when the vehicle is stationary; this causes the
engine to warm up more slowly, thereby
increasing fuel consumption and emissions. It
is therefore advisable to drive off immediately,
slowly, avoiding high speeds: by doing this the
engine will warm up more quickly. Unnecessary Actions
Avoid revving up when starting at traffic lights
or before stopping the engine. This action is
unnecessary and causes increased fuel
consumption and pollution.
Gear Selection
Use a high gear when traffic and road condi
-
tions allow it. Using a low gear for faster accel -
eration will increase fuel consumption.
Improper use of a high gear increases
consumption, emissions and engine wear.
Max. Speed
Fuel consumption considerably increases as
speed increases. Maintain a constant speed,
avoiding unnecessary braking and accelera -
tion, which cost in terms of both fuel consump -
tion and emissions.
Acceleration
Accelerating violently severely affects
consumption and emissions: acceleration
should be gradual and should not exceed the
maximum torque.Conditions Of Use
Cold Starting
Short trips and frequent cold starts will not
allow the engine to reach optimum operating
temperature. This results in a significant
increase in consumption levels (from +15 to
+30% in city driving) and emissions.

Panic Brake Assist (PBA) System
The PBA system is designed to improve the
vehicle’s braking capacity during emergency
braking.
The system detects emergency braking by
monitoring the speed and force with which the
brake pedal is pressed, and consequently
applies the optimal brake pressure. This can
reduce the braking distance: the PBA system
therefore complements the ABS.
Maximum assistance from the PBA system is
obtained by pressing the brake pedal very
quickly. In addition, the brake pedal should be
pressed continuously during braking, avoiding
intermittent presses, to get the most out of thesystem. Do not reduce pressure on the brake
pedal until braking is no longer necessary.
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 (hydro
-
planing), 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 are
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)
WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight
rolling may occur, such as on minor hills or
with a loaded vehicle, or while pulling a
trailer. HSA is not a substitute for active
driving involvement. It is always the driver’s
responsibility to be attentive to distance to
other vehicles, people, and objects, and
most importantly brake operation to ensure
safe operation of the vehicle under all road
conditions. Your complete attention is
always required while driving to maintain
safe control of your vehicle. Failure to follow
these warnings can result in a collision or
serious personal injury.
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.

SAFETY

150

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) System — If
Equipped
The BSM system uses radar sensors, located
in the rear fascia/bumper, to detect the pres -
ence of other vehicles in the rear side blind
spots of your vehicle.
Rear Sensor Location The system warns the driver about the pres
-
ence of other vehicles in the detection area by
illuminating 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).
BSM Indicator Light
When the engine is started, the warning light
illuminates briefly to signal the driver that the
system is active.
Sensors
The sensors are activated when any forward
gear is engaged at a speed higher than
approximately 6 mph (10 km/h) or when
REVERSE is engaged.
The sensors are temporarily deactivated when
the vehicle is stationary or the vehicle is in
PARK.
The detection area of the system covers
approximately one lane on both sides of the
vehicle, which is around 9 ft (3 m). This area begins from the door mirror and
extends for approximately 19 ft (6 m) towards
the rear part of the vehicle.
When the sensors are active, the system moni
-
tors the detection areas on both sides of the
vehicle and warns the driver about the
possible presence of vehicles in these areas.
While driving, the system monitors the detec -
tion zone in three different situations:
when you are being overtaken by a vehicle;
when you are overtaking a vehicle;
when a vehicle approaches from the side;
to check whether it is necessary to send a
signal to the driver on both sides.

NOTE:

The system does not alert the driver of the
presence of fixed objects (e.g. safety
barriers, poles, walls, etc.). However, in
some circumstances, the system may acti -
vate in the presence of these objects. This is
normal and does not indicate a system
malfunction.
The system does not alert the driver about
the presence of vehicles coming from the
opposite direction, in the adjacent lanes.
If a trailer is hitched to the car, the system
automatically deactivates.
21_GU_OM_EN_USC_t.book Page 150

SAFETY

154

The application of torque, as well as of the
vibration, is suppressed/inhibited if:
The torque given by the driver of the
steering wheel is high
Lateral acceleration is high
The trailer is connected to the correct
control module
At least one hand is not detected on the
steering wheel for longer than a specific
time
The turn signal is turned off

NOTE:

The steering wheel torque is not applied if the
system is unable to detect a lane and if the
direction indicator for the appropriate side has
not been switched on.
The steering wheel detects the presence of
the driver’s hands by a capacitive sensor
installed in the steering wheel and by the
applied torque measured on the steering
column.
System availability
Aggressive driving of the car, or driving on the
median lines, will prevent the correct opera -
tion of the system. In case of intervention of the stability and
braking systems (FCW, ESC, ABS) they will
prevent the system from operating.
Lane change will disable the system for a
certain period of time.
The road must also comply with some specific
characteristics, such as:
Maximum/minimum lane width.
Clearly identified and defined double yellow
lines and, for a limited period of time, a lane
with a single demarcation line.

NOTE:

In some cases, for a limited period of time, the
system may be activated by a lane with a
single median line.
In cases of good road surface conditions, the
system could correctly recognize other types
of valid lane markings (e.g. road edges, side -
walks, etc.).
Hands Presence On The Steering Wheel
Detection
The system is able to detect the presence of
the driver’s hands on the steering wheel.
When the system does not detect the pres -
ence of hands on the steering wheel for 0 to 6
seconds, the following screen will be displayed
on the instrument cluster display. No acoustic
warning will be emitted in this case. Hand Presence On The Steering Wheel Not
Detected Display (Up To 6 Seconds)
When the system does not detect the pres -
ence of hands on the steering wheel from 6 to
15 seconds, the following screen will be
displayed on the instrument cluster display. A
short acoustic signal will sound if hands are
not detected on the steering wheel for 6 to
12 seconds. A continuous signal will sound if
hands are not detected on the steering wheel
for 12 to 15 seconds.

NOTE:

Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWRs) for the front
and rear axles must not be exceeded. For
further information on GAWRs, vehicle
loading, and trailer towing
Ú
page 135.
To determine the maximum loading conditions
of your vehicle, locate the statement “The
combined weight of occupants and cargo
should never exceed XXX kg or XXX lbs” on the
Tire and Loading Information placard. The
combined weight of occupants, cargo/luggage
and trailer tongue weight (if applicable) should
never exceed the weight referenced here.
Steps For Determining Correct Load
Limit—
(1) Locate the statement “The
combined weight of occupants and
cargo should never exceed XXX kg or
XXX lbs.” on your vehicle's placard.
(2) Determine the combined weight of
the driver and passengers that will be
riding in your vehicle.
(3) Subtract the combined weight of the
driver and passengers from XXX kg or
XXX lbs. (4) The resulting figure equals the avail
-
able amount of cargo and luggage load
capacity. For example, if “XXX” amount
equals 1400 lbs. and there will be five
150 lb passengers in your vehicle, the
amount of available cargo and luggage
load capacity is 650 lbs. (1400-750
(5x150) = 650 lbs.).
(5) Determine the combined weight of
luggage and cargo being loaded on the
vehicle. That weight may not safely
exceed the available cargo and luggage
load capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer,
load from your trailer will be transferred
to your vehicle. Consult this manual to
determine how this reduces the avail -
able cargo and luggage load capacity of
your vehicle.
Metric Example For Load Limit
For example, if “XXX” amount equals 635 kg
and there will be five 68 kg passengers in your
vehicle, the amount of available cargo and
luggage load capacity is 295 kg (635-340
(5x68) = 295 kg) as shown in step 4.
NOTE:

If your vehicle will be towing a trailer, load
from your trailer will be transferred to your
vehicle. The following table shows examples
on how to calculate total load, cargo/
luggage, and towing capacities of your
vehicle with varying seating configurations
and number and size of occupants. This
table is for illustration purposes only and
may not be accurate for the seating and
load carry capacity of your vehicle.
For the following example, the combined
weight of occupants and cargo should never
exceed 865 lbs (392 kg).
