Driving
TERRAIN MANAGEMENT SYSTEM FAULT: If this message is
displayed, cycling the key may clear the fault. If the fault is not cleared
after a key cycle, have the system serviced by an authorized dealer.
MODE CHANGE NOT ACCEPTED, RETRY: If this message is
displayed, a vehicle system cannot support a mode change at the time of
driver request. Try the mode change again.
DRIVING THROUGH WATER
If driving through deep or standing
water is unavoidable, proceed very
slowly especially when the depth is
not known. Never drive through
water that is higher than the bottom
of the wheel rims (for cars) or the
bottom of the hubs (for trucks).
When driving through water, traction or brake capability may be limited.
Also, water may enter your engine's air intake and severely damage your
engine or your vehicle may stall. Driving through deep water where
the transmission vent tube is submerged may allow water into the
transmission and cause internal transmission damage.
Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal.
Wet brakes do not stop the vehicle as quickly as dry brakes.
