2424-6. Driving tips
■Tire chain installation
Observe the following precautions when installing and removing chains:
●Install and remove tire chains in a safe location.
● Install tire chains on the rear tires. Do not install tire chains on the front tires.
● Install tire chains on rear tires as tightly as possible. Retighten chains after
driving 1/4  1/2 mile (0.5  1.0 km).
● Install tire chains following the instructions provided with the tire chains.
CAUTION
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
● Use tires of the specified size.
● Maintain the recommended level of air pressure.
● Do not drive in excess of 75 mph (120 km/h), regardless of the type of
snow tires being used.
● Use snow tires on all, not just some wheels.
● 4WD models: Do not mix tires of different makes, models, tread patterns
or treadwear.
■ Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
● Do not drive in excess of the speed limit specified for the tire chains being
used, or 30 mph (50 km/h), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.

Driving
NOTICE
■To prevent the water damage
Take all necessary safety measures to ensure that water damage to the
engine or other components does not occur.
● Water entering the engine air intake will cause severe engine damage.
● Water entering the automatic transmission will cause deterioration in shift
quality, locking up of your transmission accompanied by vibration, and ulti-
mately damage.
● Water can wash the grease from wheel bearings, causing rusting and pre-
mature failure, and may also enter the differentials, transmission and
transfer case, reducing the gear oil’s lubricating qualities.
■ When you drive through water
If driving through water, such as when crossing shallow streams, first check
the depth of the water and the bottom of the river bed for firmness. Drive
slowly and avoid deep water.
■ Inspection after off-road driving
● Sand and mud that has accumulated in brake drums and around brake
discs may affect braking efficiency and may damage brake system compo-
nents.
● Always perform a maintenance inspection after each day of off-road driv-
ing that has taken you through rough terrain, sand, mud, or water. For
scheduled maintenance information, refer to the “Scheduled Maintenance
Guide” or “Owner’s Manual Supplement”.

■ Caution regarding interfer ence with electronic devices
● Your audio unit is fitted with Bluetooth
® antennas. People with implanted
pacemakers or cardiac defibrillators should maintain a reasonable dis-
tance between themselves and the Bluetooth
® antennas. The radio waves
may affect the operation of such devices.
● Before using Bluetooth
® devices, users of any electrical medical device
other than implanted pacemakers and implanted cardiac defibrillators
should consult the manufacturer of the device for information about its
operation under the influence of radio waves. Radio waves could have
unexpected effects on the operation of such medical devices.

Interior features
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the
windshield effectively.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ Outside/recirculated air mode
When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode button to the recirculated air mode. This is effective
in preventing outside air from entering the vehicle interior. During cooling
operation, setting the recirculated air mode will also cool the vehicle interior
effectively.
■ When the outside temperature exceeds 75 F (24 C) and air conditioning
system is on
● In order to reduce the air conditioning power consumption, the air condition-
ing system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
● Recirculated air mode is selected as a default mode when the engine switch
is in the “ON” position.
● It is possible to switch to outside air mode at any time by pressing .
■ When the outside temperature falls to nearly 32 F (0C)
The dehumidification function may not operate even when is
pressed.
■ Air conditioning odors
●During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
● To reduce potential odors from occurring:
It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.

3426-1. Using the air conditioning system
CAUTION
■To prevent the windshield from fogging up
● Do not use
during cool air operation in extremely humid weather. The
difference between the temperature of the outside air and that of the wind-
shield can cause the outer surface of the windshield to fog up, blocking
your vision.
■ To prevent burns (vehicles with rear view mirror defoggers and wind-
shield wiper de-icer)
● Do not touch the rear view mirror surfaces when the outside rear view mir-
ror defoggers are on.
● Do not touch the glass at lower part of the windshield or to the side of the
front pillars, when the windshield wiper de-icer is on.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.
● Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers to
defog.
