Power Folding
With the power mirror control knob in the
neutral position, move it to the power
folding position. Move the knob again to
return the mirrors to the driving position.
If the power mirror control knob is moved
again during door mirror folding (from
closed to open position and vice versa),
the movement direction is reversed.
Automatic Activation
Activating the central door locking
system from outside the vehicle
automatically folds the mirrors. The
mirrors return to the driving position
when the vehicle is then unlocked.
If the door mirrors were folded using the
power mirror control knob, they can only
be returned to the driving position by
rotating the knob again.
Note:The power folding operation can
be enabled only when the vehicle speed is
lower than 31 mph (50 km/h). They can
only be manually controlled up to that
speed.
Automatic Dimming Mirrors
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

Each tire, including the spare (if
provided), should be checked monthly
when cold and inflated to the inflation
pressure recommended 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 Tire Pressure
Monitoring System (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible and inflate
them to the proper pressure. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation 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.
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.

Oversteeroccurs when the vehicle 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. 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.
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 the system. 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.
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.

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 “Tire Pressure
Monitoring Telltale Light” will still be on.
In this situation, the “Tire Pressure
Monitoring Warning Light” will turn off
only after the tires are inflated to the
vehicle’s recommended cold placard
pressure value.
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 TPM
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
OEM wheels to assure proper TPM 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
your 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.
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 “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.
Accumulation 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 Tire Repair Kit, the
previous condition must be restored so
that the
warning light is off during
normal driving.

SAFETY

The steering wheel hub trim cover and
the upper passenger 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
Passenger Knee Air Bag mounted in the
instrument panel below the glove
compartment. The Supplemental Knee Air Bags provide enhanced protection
during a frontal impact by working
together with the seat belts,
pretensioners, and front air bags.
Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air
Bags (SABs)
This vehicle is equipped with Supplemental
Seat-Mounted Side Air Bags (SABs).
Supplemental Seat-Mounted Side Air
Bags (SABs) are located in the outboard
side of the front seats. The SABs are
marked with a “SRS AIRBAG” or
“AIRBAG” on a label or on the seat trim on
the outboard side of the seats.
The SABs may help to reduce the risk of
occupant injury during certain side
impacts, in addition to the injury
reduction potential provided by the seat
belts and body structure.
When the SAB deploys, it opens the seam
on the outboard side of the seatback’s
trim cover. The inflating SAB deploys
through the seat seam into the space
between the occupant and the door.

Air Bags only. Vehicle damage by itself is
not a good indicator of whether or not
Side Air Bags should have deployed.
The Side Air Bags will not deploy in all
side collisions, including some collisions
at certain angles, or some side collisions
that do not impact the area of the
passenger compartment. The Side Air
Bags may deploy during angled or offset
frontal collisions where the front air bags
deploy.
Side Air Bags are a supplement to the
seat belt restraint system. Side Air Bags
deploy in less time than it takes to blink
your eyes.
Warning!
Occupants, including children, who are up
against or very close to Side Air Bags can be
seriously injured or killed. Occupants,
including children, should never lean on or
sleep against the door, side windows, or
area where the side air bags inflate, even if
they are in an infant or child restraint.
Seat belts (and child restraints where
appropriate) are necessary for your
protection in all collisions. They also help
keep you in position, away from an inflating
Side Air Bag. To get the best protection
from the Side Air Bags, occupants must
wear their seat belts properly and sit
upright with their backs against the seats.
Children must be properly restrained in a
child restraint or booster seat that is
appropriate for the size of the child.
Warning!
Side Air Bags need room to inflate. Do not
lean against the door or window. Sit upright
in the center of the seat.
Being too close to the Side Air Bags
during deployment could cause you to be
severely injured or killed.
Relying on the Side Air Bags alone could
lead to more severe injuries in a collision.
The Side Air Bags work with your seat belt
to restrain you properly. In some collisions,
Side Air Bags won’t deploy at all. Always
wear your seat belt even though you have
Side Air Bags.
Note: Air bag covers may not be obvious
in the interior trim, but they will open
during air bag deployment.
Rollover Events
Side Air Bags are designed to activate in
certain rollover events. The ORC
determines whether the deployment of
the Side Air Bags in a particular rollover
event is appropriate, based on the
severity and type of collision. Vehicle
damage by itself is not a good indicator
of whether or not Side Air Bags should
have deployed.
The Side Air Bags will not deploy in all
rollover events. The rollover sensing
system determines if a rollover event
may be in progress and whether
deployment is appropriate. In the event the vehicle experiences a rollover or near
rollover event, and deployment of the
Side Air Bags is appropriate, the rollover
sensing system will also deploy the seat
belt pretensioners on both sides of the
vehicle.
The SABICs may help reduce the risk of
partial or complete ejection of vehicle
occupants through side windows in
certain rollover or side impact events.

Warning!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open
or the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the MIL to
turn on.
A fire may result if gasoline is pumped
into a portable container that is inside of a
vehicle. You could be burned. Always place
gas containers on the ground while filling.
Note: If the filler compartment is
washed with a pressure washer, keep it at
a distance of at least 8 inches (20 cm).
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.

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.
