Automatic Dimming Mirrors —
If Equipped
Like the electrochromic mirror, an
automatic dimming feature is also
available on the outside rear view
mirrors to prevent glare. The automatic
dimming button is the same for all rear
view mirrors.
Warning!
Vehicles and other objects seen in an
outside convex mirror will look smaller and
farther away than they really are. Relying
too much on side convex mirrors could
cause you to collide with another vehicle or
other object. Use your inside mirror when
judging the size or distance of a vehicle
seen in a side convex mirror.
Heated Mirrors
Push the rear defrostbutton in the
climate controls to activate the heated
mirrors.

GETTING TO KNOW YOUR VEHICLE

Warning LightWhat It Means What To Do
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. 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.
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. Immediately
restore the correct inflation pressure using the Tire
Repair Kit (refer to “Tire Repair Kit” in “In Case Of
Emergency”) and contact an authorized dealer as soon
as possible.
Tire Pressure Low
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", it is ESSENTIAL to refer to “Driving
Assistance Systems” in “Safety,” strictly complying with
the indications that you find there.

conditions require better traction, the
vehicle automatically goes to AWD
mode.
The driving mode, RWD or AWD, is
shown on the instrument cluster
display.
Note:If the system failure symbol
switches on, after starting the engine or
while driving, it means that the AWD
system is not working properly. If the
warning message activates frequently,
it is recommended to carry out the
maintenance operations.
Electronic Stability
Control (ESC) System
The ESC system improves the
directional control and stability of the
car in various driving conditions.
The ESC system corrects the car’s
understeer and oversteer, distributing
the brake force on the appropriate
wheels. The torque supplied by the
engine can also be reduced in order to
maintain control of the vehicle.
The ESC system uses sensors installed
on the car to determine the path that
the driver intends to follow and
compares it with the car’s effective
path. When the real path deviates from
the desired path, the ESC system
intervenes to counter the vehicle’s
understeer or oversteer.
Oversteer occurs when the car is
turning more than it should according
to the angle of the steering wheel.
Understeer occurs when the vehicle
is turning less than it should according
to the angle of the steering wheel.
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.
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 inappropriate 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
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.
Traction Control System
(TCS)
The system 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.

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. 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.
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.
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 car, 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
“Tire Pressure Monitoring Telltale 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 “Tire Pressure Monitoring
Telltale 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.
Lots of 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 TireKit, 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 (TPM) Sensors.
Then, drive the vehicle for 10 minutes
above 15 mph (24 km/h). The TPMS
will chime, the "TPM Telltale 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 TPM sensors.

The first stage inflator is triggered
immediately during an impact that
requires air bag deployment. A low
energy output is used in less severe
collisions. A higher energy output is
used for more severe collisions.
This vehicle may be equipped with a
driver and/or front passenger seat belt
buckle switch that detects whether the
driver or front passenger seat belt is
buckled. The seat belt buckle switch
may adjust the inflation rate of the
Advanced Front Air Bags.
This vehicle may be equipped with
driver and/or front passenger seat track
position sensors that may adjust the
inflation rate of the Advanced Front Air
Bags based upon seat position.
Warning!
No objects should be placed over or
near the air bag on the instrument panel or
steering wheel because any such objects
could cause harm if the vehicle is in a
collision severe enough to cause the air
bag to inflate.
Do not put anything on or around the air
bag covers or attempt to open them
manually. You may damage the air bags
and you could be injured because the air
bags may no longer be functional. The
protective covers for the air bag cushions
are designed to open only when the air
bags are inflating.
Relying on the air bags alone could lead
to more severe injuries in a collision. The air
bags work with your seat belt to restrain
you properly. In some collisions, air bags
won’t deploy at all. Always wear your seat
belts even though you have air bags.
Front Air Bag Operation
Front Air Bags are designed to provide
additional protection by supplementing
the seat belts. Front air bags are not
expected to reduce the risk of injury in
rear, side, or rollover collisions. The front
air bags will not deploy in all frontal
collisions, including some that may
produce substantial vehicle damage —
for example, some pole collisions, truck
underrides, and angle offset collisions.
On the other hand, depending on the
type and location of impact, front air
bags may deploy in crashes with little
vehicle front-end damage but that
produce a severe initial deceleration.
Because air bag sensors measure
vehicle deceleration over time, vehicle
speed and damage by themselves are
not good indicators of whether or not
an air bag should have deployed.
Seat belts are necessary for your
protection in all collisions, and also are
needed to help keep you in position,
away from an inflating air bag.
When the ORC detects a collision
requiring the front air bags, it signals the
inflator units. A large quantity of non-toxic gas is generated to inflate the
front air bags.
The steering wheel hub trim cover and
the upper right side of the instrument
panel separate and fold out of the way
as the air bags inflate to their full size.
The front air bags fully inflate in less
time than it takes to blink your eyes.
The front air bags then quickly deflate
while helping to restrain the driver and
front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect
the knees of the driver and front
passenger, and position the front
occupants for improved interaction with
the front air bags.
Warning!
Do not drill, cut, or tamper with the knee
impact bolsters in any way.
Do not mount any accessories to the
knee impact bolsters such as alarm lights,
stereos, citizen band radios, etc.
Supplemental Driver And Front
Passenger Knee Air Bags
This vehicle is equipped with a
Supplemental Driver Knee Air Bag
mounted in the instrument panel below
the steering column and a Supplemental

VEHICLE LOADING
Certification Label
As required by National Highway Traffic
Safety Administration regulations, your
vehicle has a certification label affixed to
the driver's side door or pillar.
This label contains the month and year
of manufacture, Gross Vehicle Weight
Rating (GVWR), Gross Axle Weight
Rating (GAWR) front and rear, and
Vehicle Identification Number (VIN). A
Month-Day-Hour (MDH) number is
included on this label and indicates the
Month, Day and Hour of manufacture.
The bar code that appears on the
bottom of the label is your VIN.
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 passengers, 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
components in the system with the
lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles
or suspension components sometimes
specified by purchasers for increased
durability does 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 conditions, 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
insure 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
appropriate 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.

Spare Tires — If Equipped
Note:
For vehicles equipped with Tire Repair
Kit instead of a spare tire, please refer
to “Tire Repair Kit” in “In Case Of
Emergency” for further information.
Caution!
Because of the reduced ground clearance,
do not take your vehicle through an
automatic car wash with a compact or
limited use temporary spare installed.
Damage to the vehicle may result.
Spare Tire Matching Original
Equipped Tire And Wheel —
If Equipped
Your vehicle may be equipped with a
spare tire and wheel equivalent in look
and function to the original equipment
tire and wheel found on the front or rear
axle of your vehicle. This spare tire may
be used in the tire rotation for your
vehicle. If your vehicle has this option,
refer to an authorized tire dealer for the
recommended tire rotation pattern.
Compact Spare Tire —
If Equipped
The compact spare is for temporary
emergency use only. You can identify if
your vehicle is equipped with a
compact spare by looking at the spare
tire description on the Tire and Loading
Information Placard located on the
driver’s side door opening or on the
sidewall of the tire. Compact spare tire
descriptions begin with the letter “T” or
“S” preceding the size designation.
Example: T145/80D18 103M.
T,S=Temporary Spare Tire
Since this tire has limited tread life, the
original equipment tire should be
repaired (or replaced) and reinstalled on
your vehicle at the first opportunity.
Do not install a wheel cover or attempt
to mount a conventional tire on the
compact spare wheel, since the wheel
is designed specifically for the compact
spare tire. Do not install more than one
compact spare tire and wheel on the
vehicle at any given time.
Warning!
Compact and collapsible spares are for
temporary emergency use only. With these
spares, do not drive more than 50 mph
(80 km/h). Temporary use spares have
limited tread life. When the tread is worn to
the tread wear indicators, the temporary
use spare tire needs to be replaced. Be
sure to follow the warnings, which apply to
your spare. Failure to do so could result in
spare tire failure and loss of vehicle control.
Full Size Spare — If Equipped
The full size spare is for temporary
emergency use only. This tire may look
like the originally equipped tire on the
front or rear axle of your vehicle, but it is
not. This spare tire may have limited
tread life. When the tread is worn to the
tread wear indicators, the temporary
use full size spare tire needs to be
replaced. Since it is not the same as
your original equipment tire, replace
(or repair) the original equipment tire
and reinstall on the vehicle at the first
opportunity.
225

Check tire pressures more often if
subject to a wide range of outdoor
temperatures, as tire pressures vary
with temperature changes.
Tire pressures change by approximately
1 psi (7 kPa) per 12°F (7°C) of air
temperature change. Keep this in mind
when checking tire pressure inside a
garage, especially in the Winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature =
32°F (0°C) then the cold tire inflation
pressure should be increased by 3 psi
(21 kPa), which equals 1 psi (7 kPa) for
every 12°F (7°C) for this outside
temperature condition.
Tire pressure may increase from 2 to
6 psi (13 to 40 kPa) during operation.
DO NOT reduce this normal pressure
build up or your tire pressure will be too
low.
Tire Pressures For High Speed
Operation
The manufacturer advocates driving at
safe speeds and within posted speed
limits. Where speed limits or conditions
are such that the vehicle can be driven
at high speeds, maintaining correct tire
inflation pressure is very important.
Increased tire pressure and reduced
vehicle loading may be required for
high-speed vehicle operation. Refer to
your authorized tire dealer or original
equipment vehicle dealer forrecommended safe operating speeds,
loading and cold tire inflation pressures.
Warning!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to
fail. You could have a serious collision. Do
not drive a vehicle loaded to the maximum
capacity at continuous speeds above
75 mph (120 km/h).
Radial Ply Tires
Warning!
Combining radial ply tires with other types
of tires on your vehicle will cause your
vehicle to handle poorly. The instability
could cause a collision. Always use radial
ply tires in sets of four. Never combine
them with other types of tires.
Tire Repair
If your tire becomes damaged, it may
be repaired if it meets the following
criteria:
The tire has not been driven on when
flat.
The damage is only on the tread
section of your tire (sidewall damage is
not repairable).
The puncture is no greater than a ¼
of an inch (6 mm).
Consult an authorized tire dealer for tire
repairs and additional information.
Damaged Run Flat tires, or Run Flat
tires that have experienced a loss of
pressure should be replaced
immediately with another Run Flat tire
of identical size and service description
(Load Index and Speed Symbol).
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to
drive 50 miles (80 km) at 50 mph
(80 km/h) after a rapid loss of inflation
pressure. This rapid loss of inflation is
referred to as the Run Flat mode. A Run
Flat mode occurs when the tire inflation
pressure is of/or below 14 psi (96 kPa).
Once a Run Flat tire reaches the run flat
mode it has limited driving capabilities
and needs to be replaced immediately.
A Run Flat tire is not repairable.
It is not recommended driving a vehicle
loaded at full capacity or to tow a trailer
while a tire is in the run flat mode.
See the tire pressure monitoring section
for more information.
Tire Spinning
When stuck in mud, sand, snow, or ice
conditions, do not spin your vehicle's
wheels above 30 mph (48 km/h) or for
longer than 30 seconds continuously
without stopping.
