required. However, the conventional brake
system will continue to operate normally if the
brake indicator light is not on.
If the ABS light is on, the brake system should
be serviced as soon as possible to restore the
benefits of Anti-Lock Brakes. If the ABS light
does not turn on when the ignition is placed in
the ON/RUN position, have the light inspected
by an authorized dealer.

Light — If Equipped
When the ignition is cycled to ON, the
indicator light illuminates, but
should turn off as soon as the engine
is started.
ESC System Intervention : Intervention by the
system is indicated by the flashing of the indi -
cator light: it indicates that the vehicle is in crit -
ical stability and grip conditions.
ESC System Failure : If the indicator light does
not turn off, or if it stays on with the engine
running, a failure was found in the ESC
system.
Hill Start Assist System Failure : The illumina-
tion of the indicator light indicates a Hill Start
Assist system failure.
In these cases, contact an authorized dealer
as soon as possible.
Electronic Stability Control (ESC) OFF

When the active safety systems are reacti -
vated, the indicator light turns off.
Tire Pressure Low Warning Light
The indicator light will illuminate to
indicate that the tire pressure is
lower than the recommended value
and/or that slow pressure loss is
occurring. In these cases, optimal tire duration
and fuel consumption may not be guaranteed.
In any situation in which the message on the
display is “See Manual”

Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a
message is displayed to indicate
that the tire pressure is lower than
the recommended value and/or that
slow pressure loss is occurring. In these cases,
optimal tire duration and fuel consumption
may not be guaranteed. Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom
-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label.
If your vehicle has tires of a different size than
the size indicated on the vehicle placard or tire
inflation pressure label, you should determine
the proper tire inflation pressure for those
tires.
As an added safety feature, your vehicle has
been equipped with a TPMS that illuminates a
low tire pressure telltale when one or more of
your tires is significantly underinflated. Accord -
ingly, when the low tire pressure telltale illumi -
nates, you should stop and check your tires as
soon as possible, and inflate them to the
proper pressure. Driving on a significantly
underinflated tire causes the tire to overheat
and can lead to tire failure. Under inflation
CAUTION!
Do not continue driving with one or more
flat tires as handling may be compromised.
Stop the vehicle, avoiding sharp braking
and steering. If a tire puncture occurs,
repair immediately using the dedicated tire
repair kit and contact an authorized dealer
as soon as possible.

also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the
driver’s responsibility to maintain correct tire
pressure, even if under inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the
malfunction indicator is illuminated, the
system may not be able to detect or signal low
tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including
the installation of replacement or alternate
tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check
the TPMS malfunction telltale after replacing
one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires
and wheels allow the TPMS to continue to
function properly.
Rear Fog Lights
The indicator illuminates when the
rear fog light is activated.
Engine Check/Malfunction Indicator Light
(MIL)
In normal conditions, when the igni-
tion is cycled to ON, the indicator
light illuminates, but it should turn
off as soon as the engine is started.
The operation of the indicator light may be
checked by the traffic police using specific
devices. Comply with the laws and regulations
of the country where you are driving. Under these conditions, the vehicle can
continue traveling at moderate speed but
without demanding excessive effort from the
engine or high speed. Prolonged use of the
vehicle with the indicator light on constantly
may cause damage. Contact an authorized
dealer as soon as possible.
Forward Collision Warning (FCW) System
This indicator light informs the driver
that the frontal collision alarm func
-
tion is not enabled.
Drive carefully and contact an authorized
dealer as soon as possible.
Fuel Reserve/Limited Range
The indicator light (or the symbol in
the display) illuminates when about
2.4 gallons (9 liters) of fuel is left in
the tank.
WARNING!
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. Aftermarket
wheels can cause sensor damage. 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 dealership to have your
sensor function checked.
CAUTION!
If, turning the ignition device to ON, the
warning light does not turn on or if it
turns on steadily or flashing when traveling
(on some versions together with the
message on the display), contact an
authorized dealer as soon as possible.

Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of
your vehicle including driver, passengers,
vehicle, options and cargo. The label also
specifies maximum capacities of front and
rear axle systems (GAWR). Total load must be
limited so GVWR and front and rear GAWR are
not exceeded.
Payload
The payload of a vehicle is defined as the
allowable load weight a truck can carry,
including the weight of the driver, all passen-
gers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load
on the front and rear axles. The load must be
distributed in the cargo area so that the GAWR
of each axle is not exceeded.
Each axle GAWR is determined by the compo -
nents in the system with the lowest load
carrying capacity (axle, springs, tires or
wheels). Heavier axles or suspension compo -
nents sometimes specified by purchasers for
increased durability do not necessarily
increase the vehicle's GVWR.
Tire Size
The tire size on the Vehicle Certification Label
represents the actual tire size on your vehicle.
Replacement tires must be equal to the load
capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the
tire size listed.
Inflation Pressure
This is the cold tire inflation pressure for your
vehicle for all loading conditions up to full
GAWR.
Curb Weight
The curb weight of a vehicle is defined as the
total weight of the vehicle with all fluids,
including vehicle fuel, at full capacity condi -
tions, and with no occupants or cargo loaded
into the vehicle. The front and rear curb weight
values are determined by weighing your
vehicle on a commercial scale before any
occupants or cargo are added.
Loading
The actual total weight and the weight of the
front and rear of your vehicle at the ground can
best be determined by weighing it when it is
loaded and ready for operation.
The entire vehicle should first be weighed on a
commercial scale to ensure that the GVWR
has not been exceeded. The weight on the
front and rear of the vehicle should then be
determined separately to be sure that the load
is properly distributed over the front and rear
axle. Weighing the vehicle may show that the
GAWR of either the front or rear axles has
been exceeded but the total load is within the specified GVWR. If so, weight must be shifted
from front to rear or rear to front as appro
-
priate until the specified weight limitations are
met. Store the heavier items down low and be
sure that the weight is distributed equally.
Stow all loose items securely before driving.
Improper weight distributions can have an
adverse effect on the way your vehicle steers
and handles and the way the brakes operate.
TRAILER TOWING
In this section you will find safety tips and
information on limits to the type of towing you
can reasonably do with your vehicle. Before
towing a trailer, carefully review this informa -
tion to tow your load as efficiently and safely
as possible.
To maintain the New Vehicle Limited Warranty
coverage, follow the requirements and recom -
mendations in this manual concerning vehi -
cles used for trailer towing.
CAUTION!
Do not load your vehicle any heavier than
the GVWR or the maximum front and rear
GAWR. If you do, parts on your vehicle can
break, or it can change the way your vehicle
handles. This could cause you to lose
control. Also overloading can shorten the
life of your vehicle.

Common Towing Definitions
The following trailer towing related definitions
will assist you in understanding the following
information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers,
cargo and tongue weight. The total load must
be limited so that you do not exceed the GVWR

Ú
page 135.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the
weight of all cargo, consumables, and equip -
ment (permanent or temporary) loaded in or
on the trailer in its "loaded and ready for oper -
ation" condition.
The recommended way to measure GTW is to
put your fully loaded trailer on a vehicle scale.
The entire weight of the trailer must be
supported by the scale.
Gross Combination Weight Rating (GCWR)

The GCWR is the total allowable weight of your
vehicle and trailer when weighed in combination.

Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the
front and rear axles. Distribute the load over
the front and rear axles evenly. Make sure that
you do not exceed either front or rear GAWR

Ú
page 135.
Tongue Weight (TW)
The tongue weight is the downward force
exerted on the hitch ball by the trailer. You
must consider this as part of the load on your
vehicle.
Trailer Frontal Area
The frontal area is the maximum height multi -
plied by the maximum width of the front of a
trailer.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer
tongue weight, just as if it were luggage
located at a hitch ball or some other
connecting point of the vehicle. These kinds of
hitches are the most popular on the market
today and they are commonly used to tow
small and medium sized trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying
leverage through spring (load) bars. They are
typically used for heavier loads to distribute
trailer tongue weight to the tow vehicle's front axle and the trailer axle(s). When used in
accordance with the manufacturer's direc
-
tions, it provides for a more level ride, offering
more consistent steering and brake control
thereby enhancing towing safety. The addition
of a friction/hydraulic sway control also
dampens sway caused by traffic and cross -
winds and contributes positively to tow vehicle
and trailer stability. Trailer Sway Control and a
weight distributing (load equalizing) hitch are
recommended for heavier Tongue Weights
(TW) and may be required depending on
vehicle and trailer configuration/loading to
comply with Gross Axle Weight Rating (GAWR)
requirements.
Trailer Hitch Classification
The following chart provides the industry stan -
dard for the maximum trailer weight a given
trailer hitch class can tow and should be used
to assist you in selecting the correct trailer
hitch for your intended towing condition.
WARNING!
It is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating is
exceeded. You could lose control of the
vehicle and have a collision.
WARNING!
An improperly adjusted Weight Distrib -
uting Hitch system may reduce handling,
stability, braking performance, and could
result in a collision.
Weight Distributing Systems may not be
compatible with Surge Brake Couplers.
Consult with the hitch and trailer manu -
facturer or a reputable Recreational
Vehicle dealer for additional information.
21_GU_OM_EN_USC_t.book Page 137

139
(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.

Hill Descent Control (HDC) System — 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.
WARNING!
Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase
the traction afforded by prevailing road
conditions. ESC cannot prevent accidents,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also
cannot prevent accidents resulting from
loss of vehicle control due to inappro -
priate driver input for the conditions. Only
a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an
ESC equipped vehicle must never be
exploited in a reckless or dangerous
manner which could jeopardize the user’s
safety or the safety of others.
Vehicle modifications, or failure to prop -
erly 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 perfor-
mance. Improperly inflated and unevenly
worn tires may also degrade ESC perfor -
mance. 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.

will turn off only after the tires are inflated to the
vehicle’s recommended cold placard pressure
value.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 infla
-
tion pressure of each tire, and inflate the
necessary tire or tires to the correct cold infla -
tion 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.
CAUTION!
The TPMS has been optimized for the orig -
inal equipment tires and wheels. TPMS
pressures and warning have been estab -
lished 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 after -
market wheels and may contribute to a
poor overall system performance or
sensor damage. Customers are encour -
aged to use OEM wheels to assure 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 pres -
sure always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could
damage the TPMS sensor.

23. Remove the jack.
24. Use the wheel wrench to fully tighten thebolts, passing alternately from one bolt to
the diagonally opposite one.
To obtain a more accurate reading, it is advis -
able 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.
TIRE SERVICE KIT — IF
EQUIPPED
Description
If a tire is punctured, you can make an emer -
gency repair using the Tire Service Kit located
in the rear storage area under the load plat -
form.
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.
Load Floor
The Tire Service Kit consists of:
Sealant cartridge containing the sealing
fluid
Filler Tube
Air compressor, complete with pressure
gauge and connectors
Adhesive label with the writing "Max.
50 mph (80 km/h)”, to be attached in a
position easily visible to the driver (e.g. on
the dashboard) after repairing the tire
WARNING!
To avoid the risk of forcing the vehicle off
the jack, do not tighten the wheel nuts fully
until the vehicle has been lowered. Failure
to follow this warning may result in serious
injury.
WARNING!
A loose tire or jack thrown forward in a
collision or hard stop could endanger the
occupants of the vehicle. Always stow the
jack parts and the spare tire in the places
provided. Have the deflated (flat) tire
repaired or replaced immediately.
