■Air conditioning system opera-
tion in Eco drive mode
In Eco drive mode, heating/cooling
operations and the fan speed is con-
trolled to improve fuel efficiency.
Perform the following procedures to
increase the air conditioning perfor-
mance.
●Vehicles with automatic air condi-
tioning system: Turn eco air condi-
tioning mode off ( P.523)
●Adjust the fan speed ( P.516,

●Normal mode and Eco drive mode
are not canceled until another
driving mode is sel ected. (Even if
the engine switch is turned off,
normal mode and Eco drive mode
will not be a utomatically can-
celed.)
Multi-terrain Select
(AWD vehicles)
When driving over muddy,
sandy or rough road sur-
faces, Multi-terrain Select
selects a suitable driving
mode to switch AWD, brake
and drive force control to
perform control suitable for
the road condition.
WARNING
■Before using Multi-terrain
Select
Make sure to observe the follow-
ing precautions. Failure to
observe these precautions may
result in an unexp ected accident.
●Check that the Mud & Sand and
Rock & Dirt indicators are illumi-
nated before driving. Multi-ter-
rain Select will not operate
when the indicators are off.
●Do not rely solely upon the
Multi-terrain Select. This func-
tion is not inten ded to expand
the limits of the vehicle. If the
system is continuously used for
a long period of time, the load
on related parts increases and
the system may be unable to
operate normally, which may
lead to an accident. Thoroughly
check the road c onditions and
driving route before driving, and
drive with caution.

3764-6. Driving tips
WARNING
●When driving off-road or in rug-
ged terrain, do not drive at
excessive speeds, jump, make
sharp turns, strike objects, etc.
This may cause loss of control
or vehicle rollover causing
death or serious injury. You are
also risking expensive damage
to your vehicle’s suspension
and chassis.
NOTICE
■To prevent the water damage
Take all necessary safety mea-
sures to ensure that water dam-
age 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 deterio-
ration in shift quality, locking up
of your transmission accompa-
nied by vibration, and ultimately
damage.
●Water can wash the grease
from wheel bearings, causing
rusting and premature failure,
and may also enter the differen-
tials, transmission and transfer
case (AWD models), reducing
the gear oil’s lub ricating quali-
ties.
■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 riverbed for
firmness. Drive slowly and avoid
deep water.
■Inspection after off-road driv-
ing
●Sand and mud that has accu-
mulated around brake discs
may affect braking efficiency
and may damage brake system
components.
●Always perform a maintenance
inspection after each day of off-
road driving 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”.
