excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or s lick roads.
■ Stopping distance when the ABS or Multi Terrain ABS is operatin g may
exceed that of normal conditions
The ABS and Multi Terrain ABS are not designed to shorten the v ehicle’s
stopping distance. Always maintain a safe distance from the vehicle in front
of you, especially in the following situations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or uneven surfaces
■ TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Drive the vehicle carefully in conditions where stability and p ower may be
lost.
■ Hill-start assist control does not operate effectively when
● Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on steep inclines and roads covered wit h ice.
● Unlike the parking brake, hill-st art assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.

• Engine coolant
• Washer fluid
● Have a service technician inspec t the condition of the battery.
● Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the rear tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
Perform the following according to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is fr ozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to p revent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
● Check for and remove any excess ic e or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to roa d con-

■ The protection circuit may be act ivated to cut the power supply if any of
the following conditions apply:
● The engine is started with the power outlet main switch on.
● Use of electrical appliances exceeding the maximum capacity is attempted.
A sound may be heard when the protection circuit is activated. This is nor-
mal and does not indicate a malfunction.
● Electrical appliances, which consume power exceeding 100 W, have been
used continuously for a long time period.
● The total power usage by all electrical features (headlights, a ir conditioning,
etc.) has exceeded the total vehicle maximum for an extended period of
time.
■ If the protection circuit is act ivated and the power supply is cut, conduct
the following procedure:
Park the vehicle in a safe place, and then securely apply the parking
brake.
Check and ensure the following conditions:
Vehicles with an automatic transmission
The shift lever is in P or N.
