If the engine has just been started, it
may take a short time for the system
to display the rearview.
The camera display brightness is
adjusted automatically by sensors. If
you use the camera display
continuously at high temperature,
the image will gradually dim and
eventually turn off automatically. If
you change to another shift position,
the camera display will come on
again when you return to reverse.
The inside mirror will be hot when
you use the monitor for an extended
period of time.
If a bright light (such as sunlight) is
reflected on the mirror, the image
may be difficult to see.
Rearview Camera Guide Line
The camera display has parking
guide lines that indicate distance
from your vehicle.
1st Line 24in (0.6m)
2nd Line 39in (1m)
3rd Line 79in (2m)
4th Line 118in (3m)
NOTE●The rearview camera has a unique
lens that makes objects appear
closer than they actually are.●The rearview camera display has a
limited coverage, and the size and
position of objects may appear
different than they actually are.
Make sure to check the
surrounding area carefully.
To turn the guide line on and off,
hold the power button for more than
3 seconds when the shift is in
reverse, the on/off setting will be
kept when you change gear and
return to reverse.

Engine Coolant CheckLook at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, seeAdding
Engine Coolant on page 424 for
information on adding the proper
coolant. Refer to
Owner's Maintenance
Checks on page 417 for information
about checking other items on your
vehicle. Actual Mileage and EPA Fuel
Economy Estimates Comparison.
Fuel economy is not a fixed number.
It varies based on driving conditions,
driving habits and vehicle condition.
Therefore, it is not possible for one
set of estimates to predict fuel
economy precisely for all drivers in
all environments.
The EPA fuel economy estimates
shown in the example to the right are
a useful tool for comparison when
buying a vehicle. EPA estimates
include:
City MPG
－Represents urban
driving in a vehicle in light traffic. A
range of miles per gallon achieved is
also provided.
Highway MPG －Represents a
mixture of rural and interstate
driving, in a warmed-up vehicle,
typical of longer trips in free-flowing
traffic. A range of miles per gallon
achieved is also provided.

You should do these checks and
adjustments before you drive your
vehicle:1. Make sure all windows, mirrors, and outside lights are clean and
unobstructed. Remove frost, snow,
or ice.
2. Check that the hood is fully closed.
3. Visually check the tires. If a tire looks low, use a gauge to check its
pressure.
4. Check that any items you may be carrying are stored properly or
fastened down securely. 5. Check the seat adjustment (see
page 134).
6. Check the adjustment of the inside and outside mirrors (see page
146).
7. Check the steering wheel adjustment (see page 122).
8. Make sure the doors and the tailgate are securely closed and
locked.
9. Fasten your seat belt. Check that your passengers have fastened
their seat belts (see page 15). 10. When you start the engine, check
the gauges and indicators in the
instrument panel, and the
messages on the multi-information
display (see pages 63, 73 and 74).

Each torque indicator is displayed as
a bar graph divided into 5 segments.
The number of segments represents
the amount of torque distributed to
each wheel.
When there is only a slight change in
torque distribution while driving,
such as cruising on level roads at the
same speed, the torque distribution
monitor may stop displaying the
amount of torque. This is not a
system problem. The monitor will
show the amount if the system
senses any change in torque
distribution.
If the SH-AWD indicator blinks while
driving, it indicates the differential
temperature is too high. You will also
see an‘‘SH-AWD DIFF TEMP
HIGH ’’message on the multi-
information display. If this happens,
pull to the side of the road when it is
safe, shift to Park, and let the engine
idle until the indicator goes out. If
the indicator does not go out, take
your vehicle to a dealer to have it
checked.
If the SH-AWD indicator on the
instrument panel stays on, and the
‘‘ CHECK SH-AWD SYSTEM ’’
message also appears on the multi-
information display, there is a
problem with the SH-AWD system.
Your vehicle still has normal front-
wheel drive with vehicle stability
assist (VSA), but does not have the
advantages of SH-AWD. Have your
vehicle checked by a dealer as soon
as possible.

Your vehicle is equipped with disc
brakes at all four wheels. A power
assist using negative pressure
generated by the engine and the
electric vacuum pump helps reduce
the effort needed on the brake pedal.
The anti-lock brake system (ABS)
helps you retain steering control
when braking very hard.
When the electric vacuum pump is in
operation, it makes some mechanical
noises come from the engine
compartment. This is normal.
When you drive in cold weather or
thinner air at high altitude, the
electric vacuum pump operates more
frequently after the engine is started.
For more information about the
electric vacuum pump, see page 468.Resting your foot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their effectiveness
and reduces brake pad life. In
addition, fuel economy can be
reduced. It also keeps your brake
lights on all the time, confusing
drivers behind you.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their
effectiveness. Use the engine to
assist the brakes by taking your foot
off the accelerator and downshifting
to a lower gear.
Check your brakes after driving
through deep water. Apply the
brakes moderately to see if they feel
normal. If not, apply them gently and
frequently until they do. Be extra
cautious and alert in your driving.Braking System Design
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the left-front brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
Brake Pad Wear Indicators
All four brakes have audible brake
wear indicators.
If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal for
the brakes to occasionally squeal or
squeak when you apply them.

Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes significantly low, the sensor
in that tire immediately sends a
signal that causes the low tire
pressure/TPMS indicator in the
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
information display along with a
‘‘CHECK TIRE PRESSURE ’’
message.
Low Tire Pressure/TPMS
Indicator
When the low tire pressure/TPMS
indicator is on, one or more of your
tires is significantly underinflated.
You should stop and check your tires
as soon as possible, and inflate them
to the proper pressure as indicated
on the vehicle's tire information
placard.
It is possible that the pressures
shown on the multi-information
display and the pressures you
manually measure are slightly
different.
If the difference is significant or you
cannot make the low tire pressure/
TPMS indicator and message on the
multi-information display go out after
inflating the tires to the specified
values, have your dealer check the
system as soon as possible. If you think you can safely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure.
If the tire is flat, or if the tire pressure
is too low to continue driving, replace
the tire with the compact spare tire
(see page 454).
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.
Because tire pressure varies by
temperature and other conditions,
the low tire pressure/TPMS
indicator may come on unexpectedly.

Diagnosing why the engine won't
start falls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position:●You hear nothing, or almost
nothing. The engine's starter
motor does not operate at all, or
operates very slowly.●You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
faster than normal, but the engine
does not start up and run.Nothing Happens or the Starter
Motor Operates Very Slowly
When you turn the ignition switch to
the START (III) position, you do not
hear the normal noise of the engine
trying to start. You may hear a
clicking sound, a series of clicks, or
nothing at all.
Check these things:
●Check the transmission interlock.
The transmission must be in Park
or neutral or the starter will not
operate.●Turn the ignition switch to the ON
(II) position. Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See
Jump Starting
on page 461.
●Turn the ignition switch to the
START (III) position. If the
headlights do not dim, check the
condition of the fuses. If the fuses
are OK, there is probably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualified mechanic to
determine the problem (see
Emergency Towing on page 475).
If the headlights dim noticeably or go
out when you try to start the engine,
either the battery is discharged or
the connections are corroded. Check
the condition of the battery and
terminal connections (see page 450).
You can then try jump starting the
vehicle from a booster battery (see
page 461).
