To Estimate the Tongue Load1. Park the vehicle on level ground.
2. Measure and record the distancefrom the ground to the bottom of
the trailer hitch.
3. Connect the fully loaded trailer to the hitch.
4. Measure again from the ground to the same spot on the bottom of the
hitch.
5. Subtract the second measurement from the first measurement, then
refer to the following table.

If the indicated required service is
not done and the remaining engine
oil life becomes 0%, the multi-
information display will show a
‘‘SERVICE PAST DUE ’’message, the
total distance traveled after the
remaining oil life became 0%, and the
maintenance item code(s). This message is displayed when you
drive over 10 miles (for U.S. models)
or 10 km (for Canadian models) after
seeing the 0% message.
Immediately have the service
performed, and make sure to reset
the display as previously described.
The message will be canceled if the
INFO (
/
) button on the steering
wheel is pressed. Press the INFO
(
/
) button to see the message
again.
When you press the SEL/RESET
button to select the engine oil life,
the message ‘‘SERVICE ’’, along with
the maintenance item code and the
total negative mileage after the oil life
became 0%, will be displayed on the
lower part of the multi-information
display.

in the multi-information display are in
code.
For an explanation of the
maintenance codes, see page 508.Resetting the Engine Oil Life
Display
Your dealer will reset the display
after completing the required
maintenance service. You will see
‘‘
OIL LIFE 100% ’’on the display the
next time you turn the ignition
switch to the ON (II) position.
If maintenance service is done by

steering wheel repeatedly until the
multi-information display shows blank,
SH-AWD and tire pressure.
3. Press and hold the SEL/RESET button on the steering wheel for more than 10
seconds. The remaining engine oil life

Check the air pressures when the
tires are cold. This means the vehicle
has been parked for at least 3 hours,
or driven less than 1 mile (1.6 km).
Add or release air, if needed, to
match the recommended cold tire
pressures.
If you check air pressures when the
tires are hot [driven for several miles
(kilometers)], you will see readings 4
to 6 psi (30 to 40 kPa, 0.3 to 0.4
kgf/cm
2) higher than the cold
readings. This is normal. Do not let
air out to match the recommended
cold air pressure. The tire will be
underinflated.
While tubeless tires have some
ability to self-seal if they are
punctured, you should look closely
for punctures if a tire starts losing
pressure. You should get your own tire
pressure gauge and use it whenever
you check your tire pressures. This
will make it easier for you to tell if a
pressure loss is due to a tire problem
and not due to a variation between
gauges.
Recommended Tire Pressures
The following chart shows the
recommended cold tire pressures for
most normal driving conditions.

High Speed Driving
We strongly recommend that you do
not drive faster than the posted
speed limits and conditions allow. If
you ever drive in a sanctioned
competitive event at sustained high
speeds (over 99 mph or 160 km/h),
be sure to adjust the cold tire
pressures as shown below. If you do
not, excessive heat can build up and
cause sudden tire failure.U.S. Advance Package, AdvancePackage with Entertainment, andCanadian Elite Package models
Tire Size Cold Tire Pressure for High Speed Driving
P255/50R19 103H Front: 33 psi (230 kPa, 2.3 kgf/cm
2)
Rear: 36 psi (260 kPa, 2.6 kgf/cm2)
Tire Inspection
Every time you check inflation, you
should also examine the tires for
damage, foreign objects, and wear.
You should look for:●
Bumps or bulges in the tread or
side of the tire. Replace the tire if
you find either of these conditions.
●
Cuts, splits, or cracks in the side of
the tire. Replace the tire if you can
see fabric or cord.
●
Excessive tread wear.
Your tires have wear indicators
molded into the tread. When the
tread wears down, you will see a 1/2
inch (12.7 mm) wide band across the
tread. This shows there is less than
1/16 inch (1.6 mm) of tread left on
the tire.
A tire this worn gives very little
traction on wet roads. You should
replace the tire if you can see three
or more tread wear indicators.

It is best to replace all four tires at
the same time. If that is not possible
or necessary, replace the two front
tires or two rear tires as a pair.
Replacing just one tire can seriously
affect your vehicle's handling.
If you ever replace a wheel, make
sure that the wheel's specifications
match those of the original wheels.
Also be sure you use only TPMS
specific wheels. If you do not, the tire
pressure monitoring system will not
work.
Replacement wheels are available at
your dealer.
Installing improper tires on your
vehicle can affect handling and
stability. This can cause a crash
in which you can be seriously
hurt or killed.
Always use the size and type of
tires recommended in this
owner's manual.

Winter Driving
Tires marked ‘‘M ＋ S’’ or ‘‘All
Season ’’on the sidewall have an all-
weather tread design suitable for
most winter driving conditions.
For the best performance in snowy
or icy conditions, you should install
snow tires or tire chains. They may
be required by local laws under
certain conditions.

passenger's side.
To open it, push the tabs as shown. Checking and Replacing Fuses
If something electrical in your
vehicle stops working, the first thing
you should check for is a blown fuse.
Determine from the chart on pages
563, 564, and 565, or the diagram on
the fuse box lid, which fuse or fuses
control that device. Check those
fuses first, but check all the fuses
before deciding that a blown fuse is
the cause. Replace any blown fuses,
and check if the device works.
1. Turn the ignition switch to the
LOCK (0) position. Make sure the
headlights and all other
accessories are off.
2. Remove the cover from the fuse box.
