brake the vehicle. This can help avoid
or lessen the severity of crashes when
driving in a forward gear.
SeeForward Automatic Braking (FAB)
0 215.
Lane Departure
Warning (LDW)
If equipped, LDW may help avoid
unintentional lane departures at
speeds of 56 km/h (35 mph) or greater.
LDW uses a camera sensor to detect
the lane markings. The LDW light,
@,
is green if a lane marking is detected.
If the vehicle departs the lane, the
light will change to amber and flash.
In addition, beeps will sound or the
driver seat will pulse.
See Lane Departure Warning (LDW)
0 219.
Lane Keep Assist (LKA)
If equipped, LKA may help avoid
crashes due to unintentional lane
departures. It may assist by gently
turning the steering wheel if the
vehicle approaches a detected lane marking without using a turn signal in
that direction. It may also provide a
Lane Departure Warning (LDW) alert
as the lane marking is crossed. The
system will not assist or alert if it
detects that you are actively steering.
Override LKA by turning the steering
wheel. LKA uses a camera to detect
lane markings between 60 km/h (37
mph) and 180 km/h (112 mph).
See
Lane Departure Warning (LDW)
0 219 and Lane Keep Assist (LKA)
0 220.
Side Blind Zone
Alert (SBZA)
If equipped, SBZA will detect moving
vehicles in the next lane over in the
vehicle's side blind zone area. When
this happens, the SBZA display will
light up in the corresponding outside
side mirror and will flash if the turn
signal is on.
See Side Blind Zone Alert (SBZA) 0217.
Lane Change Alert (LCA)
If equipped, the LCA system is a
lane-changing aid that assists drivers
with avoiding lane change crashes
that occur with moving vehicles in the
side blind zone (or spot) areas or with
vehicles rapidly approaching these
areas from behind. The LCA warning
display will light up in the
corresponding outside mirror and will
flash if the turn signal is on. The Side
Blind Zone Alert (SBZA) system is
included as part of the LCA system.
See Side Blind Zone Alert (SBZA) 0217
and Lane Change Alert (LCA) 0217.
Surround Vision
If equipped, views around the vehicle
appear in the infotainment display to
aid with parking and low-speed
maneuvers.
See “Surround Vision ”under
Assistance Systems for Parking or
Backing 0207.

Control 0193.
Tire Pressure Monitor
This vehicle may have a Tire Pressure
Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in pressure
of one of the vehicle's tires. If the
warning light comes on, stop as soon
as possible and inflate the tires to the
recommended pressure shown on the
Tire and Loading Information label.
See Vehicle Load Limits 0176. The
warning light will remain on until the
tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the tire pressures are getting low and the tires
need to be inflated to the proper
pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See
Tire Pressure Monitor System

Fuel (LFX 3.6L V6 Engine)
Regular Fuel
Use only unleaded gasoline rated
87 octane or higher in your vehicle.
Do not use gasoline with an octane
rating lower as it may result in vehicle
damage and lower fuel economy. See
Fuel 0222.
Fuel (LF3 3.6L Twin Turbo
V6 Engine)
Premium Required Fuel
Use premium 93 octane unleaded
gasoline in your vehicle. Unleaded
gasoline with a 91 octane rating may
be used, but it will reduce
performance and fuel economy. See
Fuel 0222.

transmitter will start the vehicle.
If the transmitter is ever damaged,
you may not be able to start your
vehicle.
When trying to start the vehicle, the
security light may come on briefly
when the ignition is turned on.
If the engine does not start and the
security light stays on, there is a
problem with the system. Turn the
ignition off and try again.
If the vehicle will not change ignition
modes (ACC/ACCESSORY, on, off), and
the RKE transmitter appears to be
undamaged, try another transmitter.
Or, you may try placing the
transmitter in the transmitter pocket
in the center console.
If the ignition modes will not change
with the other transmitter, or with the
transmitter in the transmitter pocket,
your vehicle needs service. If the
ignition does change modes, the first
transmitter may be faulty. See your
dealer who can service the
theft-deterrent system and have a new
RKE transmitter programmed to the
vehicle.It is possible for the immobilizer
system to learn new or replacement
RKE transmitters. Up to eight
transmitters can be programmed for
the vehicle. To program additional
transmitters, see

Transmitters to the Vehicle ”under
Remote Keyless Entry (RKE) System

Do not leave the transmitter or device
that disarms or deactivates the
theft-deterrent system in the vehicle.Exterior Mirrors
Convex Mirrors
{Warning
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you cut
too sharply into the right lane, you
could hit a vehicle on the right.
Check the inside mirror or glance
over your shoulder before changing
lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from the
driver seat.

this applies force to the strong
pelvic bones and you would be
less likely to slide under the lap
belt. If you slid under it, the belt
would apply force on your
abdomen. This could cause serious
or even fatal injuries.
. Wear the shoulder belt over the
shoulder and across the chest.
These parts of the body are best
able to take belt restraining forces.
The shoulder belt locks if there is
a sudden stop or crash.
{Warning
You can be seriously injured,
or even killed, by not wearing your
seat belt properly.
. Never allow the lap or
shoulder belt to become loose
or twisted.
. Never wear the shoulder belt
under both arms or behind
your back.
. Never route the lap or
shoulder belt over an armrest.
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt.
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. If the seat has a seat belt guide, the seat belt must be routed
through the guide to properly
position the shoulder belt. If the
seat belt is not routed through
the guide, slide the edge of the
belt webbing through the
opening on the guide. Be sure
the belt is not twisted.
2. Adjust the seat, if the seat is adjustable, so you can sit up
straight. To see how, see “Seats”
in the Index.
3. Pick up the latch plate and pull
the belt across you. Do not let it
get twisted.
The lap-shoulder belt may lock if
you pull the belt across you very
quickly. If this happens, let the
belt go back slightly to unlock it.
Then pull the belt across you
more slowly.
If the shoulder portion of a
passenger belt is pulled out all
the way, the child restraint
locking feature may be engaged.
If this happens, let the belt go
back all the way and start again.
