Alert occurs, the brake system may prepare
for driver braking to occur more rapidly
which can cause a brief, mild deceleration.
Continue to apply the brake pedal as
needed.

Automatic Braking
If I-AEB detects it is about to crash into an
intersecting vehicle, and the brakes have not
been applied, I-AEB may automatically brake
moderately or hard. This can help to avoid
some crashes or lessen impact by reducing the speed of the vehicle. Always wear a seat
belt and check that all passengers are
properly restrained. I-AEB can automatically
brake between 15 km/h (9 mph) and
80 km/h (50 mph). Automatic braking levels
may be reduced under certain conditions,
such as higher speeds.
I-AEB may slow the vehicle to a complete
stop to try to avoid a potential crash. If this
happens, I-AEB may engage the Electric
Parking Brake (EPB) to hold the vehicle at a
stop. Release the EPB or firmly press the
accelerator pedal to continue driving.
I-AEB may also apply the brakes
automatically when there is an intersecting
vehicle at risk of collision and the system
determines that the driver is not braking
with sufficient force.
Minor brake pedal pulsations or pedal
movement during this time is normal and
the brake pedal should continue to be
applied as needed.
{Warning
I-AEB may automatically brake or increase
vehicle braking in situations when it may
not be necessary or desired. Your vehicle
(Continued)
Warning (Continued)
could block the flow of traffic. I-AEB may
respond to stationary or parked vehicles,
signs, and other non-moving objects. To
override AEB, firmly press the accelerator
pedal, if it is safe to do so.
{Warning
Using I-AEB while towing a trailer could
cause you to lose control of the vehicle
and crash. Turn the system to Alert or
Off when towing a trailer.
Cleaning the System
If I-AEB does not seem to operate properly,
cleaning the outside of the windshield in
front of the rearview mirror may correct the
issue.
Front Pedestrian Braking (FPB)
System
If equipped, the FPB system may help avoid
or reduce the harm caused by front-end
crashes with nearby pedestrians or bicyclists
when driving in a forward gear. FPB displays
an amber indicator,
~, when a nearby

240 Driving and Operating
Without Head-Up Display
When the vehicle approaches a pedestrian
or bicyclist ahead too rapidly, the red FPB
alert display will flash on the windshield.
Eight rapid high-pitched beeps will sound
from the front, or both sides of the Safety
Alert Seat will pulse five times. When this
Pedestrian Alert occurs, the brake system
may prepare for driver braking to occur
more rapidly which can cause a brief, mild
deceleration. Continue to apply the brake
pedal as needed. Cruise control may be
disengaged when the Front Pedestrian Alert
occurs.
Automatic Braking
If FPB detects it is about to crash into a
pedestrian or bicyclist directly ahead, and
the brakes have not been applied, FPB may
automatically brake moderately or brake
hard. This can help to avoid some very low
speed pedestrian or bicyclist crashes or
reduce pedestrian injury. FPB can automatically brake to detected pedestrians
or bicyclists or bicyclists between 8 km/h
(5 mph) and 80 km/h (50 mph). Automatic
braking levels may be reduced under certain
conditions, such as higher speeds.
If this happens, Automatic Braking may
engage the Electric Parking Brake (EPB) to
hold the vehicle at a stop. Release the EPB.
A firm press of the accelerator pedal will
also release Automatic Braking and the EPB.
{Warning
FPB may alert or automatically brake the
vehicle suddenly in situations where it is
unexpected and undesired. It could falsely
alert or brake for objects similar in shape
or size to pedestrians or bicyclists,
including shadows. This is normal
operation and the vehicle does not need
service. To override Automatic Braking,
firmly press the accelerator pedal, if it is
safe to do so.
Automatic Braking can be disabled through
vehicle settings.To view available settings
from the infotainment screen, touch Settings
> Vehicle > Collision/Detection Systems >
Front Pedestrian Detection.
{Warning
Using AEB or IBA while towing a trailer
could cause you to lose control of the
vehicle and crash. Turn the system to
Alert or Off when towing a trailer.
Cleaning the System
If FPB does not seem to operate properly,
cleaning the outside of the windshield in
front of the rearview mirror may correct the
issue.
Side Blind Zone Alert (SBZA)
If equipped, the SBZA system is a
lane-changing aid that assists drivers with
avoiding crashes that occur with moving
vehicles in the side blind zone, or blind spot
areas. When the vehicle is in a forward gear,
the left or right side mirror display will light
up if a moving vehicle is detected in that
blind zone. If the turn signal is activated and
a vehicle is also detected on the same side,
the display will flash as an extra warning
not to change lanes. Since this system is
part of the Lane Change Alert (LCA) system,
read the entire LCA section before using this
feature.

How to Add Coolant to the Surge Tank
{Warning
Spilling coolant on hot engine parts can
burn you. Coolant contains ethylene
glycol and it will burn if the engine parts
are hot enough.
{Warning
Steam and scalding liquids from a hot
cooling system are under pressure.
Turning the pressure cap, even a little,
can cause them to come out at high
speed and you could be burned. Never
turn the cap when the cooling system,
including the pressure cap, is hot. Wait
for the cooling system and pressure cap
to cool.
Caution
Failure to follow the specific coolant fill
procedure could cause the engine to
overheat and could cause system
damage. If coolant is not visible in the
surge tank, contact your dealer.The coolant surge tank pressure cap can be
removed when the cooling system, including
the surge tank pressure cap and upper
radiator hose, is no longer hot.
1. Turn the pressure cap slowly
counterclockwise. If a hiss is heard, wait
for that to stop. A hiss means there is
still some pressure left.
2. Keep turning the pressure cap slowly and remove it.
3. If topping off the level in the coolantsurge tank, add the proper mixture until
the level reaches the mark on the front
of the tank and replace the cap. Operate
the vehicle. Repeat steps 1–3, as
necessary.
If filling the system (such as after
servicing), follow the Automatic Coolant
Service Fill Instructions.
Caution
If the pressure cap is not tightly installed,
coolant loss and engine damage may
occur. Be sure the cap is properly and
tightly secured.
Automatic Coolant Service Fill
Instructions
This feature assists in filling and removing
air from the cooling system after service of
components or when coolant is added after
being too low.
To activate the fill and air removal process:
1. With a cold system, add coolant to the indicated mark on the surge tank.
2. Replace the cap on the surge tank.
3. Connect the vehicle to a battery charger.

4. Turn the ignition to Service Mode. SeeIgnition Positions 0174.
5. Turn off the air conditioning.
6. Set the parking brake.
7. At the same time, press the accelerator and the brake for automatic transmission
vehicles for two seconds, then release.
At the end of the cycle, check the coolant
level in the surge tank and add coolant if it
is low. Turn off the vehicle, allow the
Electronic Control Module (ECM) to go to
sleep, about 2 minutes, and repeat Steps 3-7.
Listen for pump activation and movement of
the control valves while watching the level
of the coolant in the surge tank. If the tank
empties, turn the ignition off, carefully
remove the surge tank cap, refill to the
indicated mark, and repeat Steps 3-6. The fill
and air removal process will run for
approximately 10 minutes.
Engine Overheating
The vehicle has several indicators to warn of
the engine overheating. There is an engine coolant temperature
gauge on the instrument cluster. See
Engine
Coolant Temperature Gauge 099. The
vehicle may also display a message on the
Driver Information Center (DIC).
If the decision is made not to lift the hood
when this warning appears, get service help
right away. See Roadside Assistance Program
0 343.
If the decision is made to lift the hood,
make sure the vehicle is parked on a level
surface. Then check to see if the engine
cooling fan is running. If the engine is
overheating, the fan should be running. If it
is not, do not continue to run the engine.
Have the vehicle serviced.
Caution
Do not run the engine if there is a leak
in the engine cooling system. This can
cause a loss of all coolant and can
damage the system and vehicle. Have
any leaks fixed right away.
If Steam Is Coming from the Engine
Compartment
{Warning
Steam and scalding liquids from a hot
cooling system are under pressure.
Turning the pressure cap, even a little,
can cause them to come out at high
speed and you could be burned. Never
turn the cap when the cooling system,
including the pressure cap, is hot. Wait
for the cooling system and pressure cap
to cool.
If No Steam Is Coming from the Engine
Compartment
If an engine overheat warning is displayed
but no steam can be seen or heard, the
problem may not be too serious. Sometimes
the engine can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
If the overheat warning is displayed with no
sign of steam: 1. Turn the air conditioning off.

Compact Spare Tire
{Warning
Driving with more than one compact
spare tire at a time could result in loss of
braking and handling. This could lead to a
crash and you or others could be injured.
Use only one compact spare tire at
a time.
If this vehicle has a compact spare tire, it
was fully inflated when new; however, it
can lose air over time. Check the inflation
pressure regularly. It should be 420 kPa
(60 psi).
Stop as soon as possible and check that the
spare tire is correctly inflated after being
installed on the vehicle. The compact spare
tire is designed for temporary use only. The
vehicle will perform differently with the
spare tire installed and it is recommended
that the vehicle speed be limited to 80 km/h
(50 mph). To conserve the tread of the spare
tire, have the standard tire repaired or
replaced as soon as convenient and return
the spare tire to the storage area. When using a compact spare tire, the AWD
(if equipped), ABS, and Traction Control
systems may engage until the spare tire is
recognized by the vehicle, especially on
slippery roads. Adjust driving to reduce
possible wheel slip.
Caution
When the compact spare is installed, do
not take the vehicle through an
automatic car wash with guide rails. The
compact spare can get caught on the rails
which can damage the tire, wheel, and
other parts of the vehicle.
Do not use the compact spare on other
vehicles.
Do not mix the compact spare tire or wheel
with other wheels or tires. They will not fit.
Keep the spare tire and its wheel together.
Caution
Tire chains will not fit the compact spare.
Using them can damage the vehicle and
the chains. Do not use tire chains on the
compact spare.
