CAUTION
A recommended tongue load or
king pin weight varies in accor-
dance with the types of trailers or
towing as described below.
In order to ensure the recom-
mended values shown below, the
trailer must be loaded by referring
to the following instructions.
1. Conventional Towing
The tongue load is 9 to 11 % of
the Gross Trailer weight.
If the gross trailer weight is over
907 kg (2000 lbs), it is necessary
to use a sway control device with
sufficient capacity.
If the gross trailer weight is over
2268 kg (5000 lbs), it is necessary
to use a weight distributing hitch
with sufficient capacity.
If using a weight distributing
hitch when towing, keep your ve-
hicle level with the ground.
2. Fifth wheel TowingThe king pin weight is 15 to 25
% of the Gross Trailer weight.
Current fifth wheel trailer designs
are not compatible with Short bed
(Crew Max models).Trailer hitch assemblies have differ-
ent weight capacities established by
the hitch manufacturer. Even though
the vehicle may be physically capa-
ble of towing a higher weight, the
operator must determine the maxi-
mum weight rating of the particular
hitch assembly and never exceed
the maximum weight rating speci-
fied for the trailer hitch. Exceeding
the maximum weight rating set by
the trailer hitch manufacturer can
cause an accident resulting in death
or serious personal injuries.

Keep your tire inflation pressures
at the proper level.
The recommended cold tire inflation
pressures, tire sizes and the com-
bined weight of occupants and cargo
(vehicle capacity weight) are de-
scribed on page 580 in Section 8.
They are also described on the tire
and loading information label as
shown.
You should check the tire inflation
pressure every two weeks, or at least
once a month. And do not forget the
spare! The following instructions for
checking tire inflation pressure
should be observed:
The pressure s hould be
checked only when the tires are
cold. If your vehicle has been
parked for at least 3 hours and has
not been driven for more than 1.5
km or 1 mile since, you will get
an accurate cold tire inflation pres-
sure reading.
Always use a tire pressure
gauge. The appearance of a tire
can be misleading. Besides, tire
inflation pressures that are even
just a few pounds off can degrade
ride and handling.
Do not bleed or reduce tire
inflation pressure after driving.
It is normal for the tire inflation
pressure to be higher after driving.
Never exceed the vehicle capac-
ity weight. Passenger and lug-
gage weight should be located so
that the vehicle is balanced.

INSPECTION AND ADJUSTMENT
PROCEDURE
1. Remove the tire valve cap.
2. Press the tip of the tire pressure gauge to the tire valve.
3. Read the pressure using the grad- uations of the gauge.
4. In case the tire inflation pressure
is not within the prescribed range,
insert the compressed air from the
valve. In case of applying too
much air, press the center of the
valve and release the air to adjust.

See “If you have a flat tire” on page
503 in Section 4 for tire change proce-
dure.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out −
of −balance wheels, or severe braking.
The tire pressure warning system
must be initialized when rotating
tires, in case that the specified tire
inflation pressure is different
between front and rear. See “Tire
pressure warning system” on page
254 in Section 1 7.WHEN TO USE SNOW TIRES OR
CHAINS
Snow tires or chains are recommended
when driving on snow or ice.
On wet or dry roads, conventional tires
provide better traction than snow tires.
SNOW TIRE SELECTION
If you need snow tires, select tires of
the same size, construction and load
capacity as the originally installed tires.
Also, on four wheel drive models, all
the tires must be the same brand and
have the same tread patterns.
Do not use tires other than those men-
tioned above. Do not install studded tires
without first checking local regulations for
possible restrictions.
CAUTION
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.
Do not use snow tires other than
the manufacturer ’s recommended si-
ze, as this may cause dangerous
handling characteristics resulting in
loss of control.
Four wheel drive models:
Do not use snow tires of different
brands, sizes, construction or tread
patterns, as this may cause danger-
ous handling characteristics result-
ing in loss of control.
SNOW TIRE INSTALLATION
Snow tires should be installed on all
wheels.
Installing snow tires on the rear wheels
only can lead to an excessive difference
in road grip capability between the front
and rear tires which could cause loss of
vehicle control.
When storing removed tires, you should
store them in a cool dry place.
Mark the direction of rotation and be sure
to install them in the same direction when
replacing.
CAUTION
Do not drive with the snow tires
incorrectly inflated.
Never drive over 120 km/h (75 mph)
with any type of snow tires.
