WARNING
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the information display
monitor may respond slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and t he new gear
number appearing on the display. This lag could cause the drive r to down-
shift again, causing rapid and excessive engine braking and pos sibly an
accident resulting in personal death or injury.
NOTICE
■ To prevent damage to the engine and its components
● Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
● The engine may be overheating if the engine coolant temperature gauge is
in the red zone (H). In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. ( P. 6 1 7 )

Driving
WARNING
●Do not leave a door or window open if the curved glass is coate d with a
metallized film such as a silver-colored one. Reflected sunligh t may cause
the glass to act as a lens, causing a fire.
● On vehicles with an automatic transmission, always apply the pa rking
brake, shift the shift lever to P, stop the engine and lock the vehicle.
Do not leave the vehicle unattended while the engine is running .
If the vehicle is parked with the shift lever in P but the park ing brake is not
set, the vehicle may start to move, possibly leading to an acci dent.
● Do not touch the exhaust pipes while the engine is running or i mmediately
after turning the engine off.
Doing so may cause burns.
■ When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift
lever or depress the accelerator pedal, this could cause an acc ident or fire
due to engine overheating. Additionally, if the vehicle is park ed in a poorly
ventilated area, exhaust gases may collect and enter the vehicl e, leading to
death or a serious health hazard.
■ When braking
● When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this ma y cause
one side of the vehicle to brake differently than the other sid e. Also, the
parking brake may not securely hold the vehicle.
● If the power brake assist function does not operate, do not fol low other
vehicles closely and avoid hills or sharp turns that require br aking.
In this case, braking is still possible, but the brake pedal sh ould be
depressed more firmly than usual. Also, the braking distance wi ll increase.
Have your brakes fixed immediately.
● Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.
● The brake system consists of 2 individual hydraulic systems; if one of the
systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking dist ance will
increase. Have your brakes fixed immediately.
■ If the vehicle becomes stuck
Do not spin the wheels excessively when any of the tires is up in the air, or
the vehicle is stuck in sand, mud, etc. This may damage the driveline com-
ponents or propel the vehicle forward or backward, causing an a ccident.

1864-1. Before driving
●Slow down before making a turn, in crosswinds, on wet or slippe ry
surfaces, etc.
Increasing vehicle speed can destabilize the trailer.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the lengt h of
your trailer, and be sure you have plenty of room before changi ng
lanes.
● Vehicles with an automatic transmission: To maintain engine bra k-
ing efficiency and charging system performance when using engin e
braking, do not use the transmission in D. If in the S mode, th e
transmission shift range posit ion must be in 5 or lower.
● Vehicles with a manual transmiss ion: To maintain engine braking
efficiency and charging system performance when using engine
braking, do not use the sixth gear.
● Instability happens more frequently when descending steep or lo ng
downhill grades. Before descending, slow down and downshift. Do
not make sudden downshifts while descending steep or long down-
hill grades.
● Avoid holding the brake pedal down too long or applying the bra kes
too frequently. This could cause the brakes to overheat and result in
reduced braking efficiency.
● Due to the added load of the trailer, your vehicle’s engine may over-
heat on hot days (at temperatures over 85°F [30°C]) when drivin g
up a long or steep grade. If the engine coolant temperature gau ge
indicates overheating, immediately turn off the air conditionin g (if in
use), pull your vehicle off the road and stop in a safe spot.
(  P. 617)
