4X4 provides electronically locked four-wheel drive power to front and
rear wheels. The RTT location in the message center will display “4X4”
when this position is selected. This position is not recommended for use
on dry pavement. This position is only intended for severe winter or
off-road conditions, such as deep snow, ice or shallow sand.
Utility and four-wheel drive vehicles are not designed for cornering
at speeds as high as passenger cars any more than low-slung sports
cars are designed to perform satisfactorily under off-road conditions.
Avoid sharp turns or abrupt maneuvers in these vehicles.
Note: The Control Trac selector switch should not be changed while the
rear wheels are slipping.
Shifting between modes
Press any button (4X2, 4X4 AUTO or 4X4) at any forward speed up to
55 mph (88 km/h). The message center may display “4X4 SHIFT IN
PROGRESS” during the system shift. The RTT location in the message
center will then display “4X4 AUTO” if 4X4 AUTO is selected or “4X4” if
4X4 is selected.
Note: Some noise may be heard as the system shifts or engages.
Driving off-road with truck and utility vehicles
Four–wheel drive vehicles are specially equipped for driving on sand,
snow, mud and rough terrain and have operating characteristics that are
somewhat different from conventional vehicles, both on and off the road.
The AdvanceTrac威 with RSC stability enhancement system can be turned
off manually by pressing the AdvanceTrac威 with RSC button (refer to
AdvanceTrac威 with Roll Stability Control (RSC) Stability
Enhancement System in this chapter) while operating in 4X2, 4X4
AUTO or 4X4 while driving in deep sand, very deep snow or more
strenuous off-road maneuvers. This will disable the engine management
feature, allowing the vehicle to maintain full power and enhanced
momentum through the obstacle.
How your vehicle differs from other vehicles
Truck and utility vehicles can differ from some other vehicles. Your
vehicle may be higher to allow it to travel over rough terrain without
getting hung up or damaging underbody components.
The differences that make your vehicle so versatile also make it handle
differently than an ordinary passenger car.
