218 Four-Wheel Drive (If Equipped) If your vehicle gets stuck WARNING: Do not spin the wheels at over 35 mph (56 km/h). The tires may fail and injure a passenger or bystander. Note: Do not rock the vehicle if the engine is not at normal operating temperature or damage to the transmission may occur. Note: Do not rock the vehicle for more than a few minutes or damage to the transmission and tires may occur or the engine may overheat. If your vehicle gets stuck in mud or snow it may be rocked out by shifting between forward and reverse gears, stopping between shifts, in a steady pattern. Press lightly on the accelerator in each gear. Emergency maneuvers • In an unavoidable emergency situation where a sudden sharp turn must be made, remember to avoid over-driving your vehicle, i.e., turn the steering wheel only as rapidly and as far as required to avoid the emergency. Excessive steering will result in less vehicle control, not more. Additionally, smooth variations of the accelerator and/or brake pedal pressure should be utilized if changes in vehicle speed are called for. Avoid abrupt steering, acceleration or braking which could result in an increased risk of loss of vehicle control, vehicle rollover and/or personal injury. Use all available road surface to return the vehicle to a safe direction of travel. • In the event of an emergency stop, avoid skidding the tires and do not attempt any sharp steering wheel movements. • If the vehicle goes from one type of surface to another (i.e., from concrete to gravel) there will be a change in the way the vehicle responds to a maneuver (steering, acceleration or braking). Again, avoid these abrupt inputs. Sand When driving over sand, try to keep all four wheels on the most solid area of the trail.

If your vehicle gets stuck

WARNING:

Do not spin the wheels at over 35 mph (56 km/h).

The tires may fail and injure a passenger or bystander.

Note:

Do not rock the vehicle if the engine is not at normal operating

temperature or damage to the transmission may occur.

Note:

Do not rock the vehicle for more than a few minutes or damage to

the transmission and tires may occur or the engine may overheat.

If your vehicle gets stuck in mud or snow it may be rocked out by

shifting between forward and reverse gears, stopping between shifts,

in a steady pattern. Press lightly on the accelerator in each gear.

Emergency maneuvers

•

In an unavoidable emergency situation where a sudden sharp turn

must be made, remember to avoid over-driving your vehicle, i.e., turn

the steering wheel only as rapidly and as far as required to avoid the

emergency. Excessive steering will result in less vehicle control, not

more. Additionally, smooth variations of the accelerator and/or brake

pedal pressure should be utilized if changes in vehicle speed are called

for. Avoid abrupt steering, acceleration or braking which could result

in an increased risk of loss of vehicle control, vehicle rollover and/or

personal injury. Use all available road surface to return the vehicle

to a safe direction of travel.

•

In the event of an emergency stop, avoid skidding the tires and do not

attempt any sharp steering wheel movements.

•

If the vehicle goes from one type of surface to another (i.e., from

concrete to gravel) there will be a change in the way the vehicle

responds to a maneuver (steering, acceleration or braking). Again,

avoid these abrupt inputs.

Sand

When driving over sand, try to keep all four wheels on the most solid

area of the trail. Avoid reducing the tire pressures but shift to a lower

gear and drive steadily through the terrain. Apply the accelerator slowly

and avoid spinning the wheels.

Avoid excessive speed because vehicle momentum can work against you

and cause the vehicle to become stuck to the point that assistance may

be required from another vehicle. Remember, you may be able to back

out the way you came if you proceed with caution.
