Towing recommendations
Always check with state and local authorities before attempting to tow another vehiclebecause this type of towing is subject to regula-tions regarding maximum towing speed, lengthand type of towing device, lighting, etc.
Towing your vehicle behind another
vehicle
1. After securely attaching the towing line to both vehicles, put the gear selector in posi- tion N and release the parking brake.
2. Put the ignition in mode II by turning the
start knob to START (without depressing
the brake pedal) and hold it in this position
for approx. 4 seconds. Release the knob.
3. Put the gear selector in position N and
release the parking brake.
4. The towing vehicle can now begin driving.
5. Keep the tow rope taut when the towing vehicle slows down by applying light pressure on the brake pedal. This will help prevent jar-ring movements of the vehicle being towed.
6. Be prepared to apply the brakes to stop the vehicle being towed.
CAUTION
General towing precautions:
• If the vehicle's battery is dead, an auxiliary battery will be necessary to provide cur-rent for releasing the electric parkingbrake and to move the gear selector from the
P position to N. If this is not possible,
use the shiftlock override procedure tomanually release the gear selector from P
and move it to N.
• Maximum speed: 50 mph (80 km/h). Do not exceed the maximum allowable tow-ing speed.
• Maximum distance with front wheels onground: 50 miles (80 km).
• The vehicle should only be towed in theforward direction.
WARNING
• When the vehicle is being towed, the igni- tion should be in mode
II (in mode I, all of
the vehicle's airbags are deactivated).
• The remote key must remain inside the vehicle.
• The power brakes and power steering willnot function when the engine is not run-ning. Approximately 5 times more pres-sure will be required on the brake pedaland the steering wheel will be considera-bly harder to turn.
• The towing eyelets must not be used forpulling the vehicle out of a ditch or forany similar purpose involving severestrain.

Loading modeUse the buttons in the cargo compartment to raise or lower the vehicle to make loading orunloading easier or when attaching a trailer.
Parking the vehicleWhen parking, be sure that there is adequatespace above and below the vehicle since itsground clearance may vary, e.g., depending onthe ambient temperature, how the vehicle is loa-ded, if loading mode is being used or the drivemode selected after the engine is started. The level may also be adjusted for a certain time after the vehicle has been parked to compensatefor possible height adjustments due to tempera-ture changes in the pneumatic suspension whenthe vehicle has cooled.
TransportWhen transporting the vehicle on a ferry, train ora tow truck, it may only be secured (lashed)around the tires, not using any other chassiscomponents. Changes in the pneumatic suspen-sion may occur during transport that could nega-tively affect the lashing and result in damage.
