Engine management VOLKSWAGEN TIGUAN 2010 Owners Manual

WARNING
Off-road driving can be dangerous, can lead to accidents, vehicle damage, stranding in remote areas, and serious personal injury.
x Never drive too fast or for terrain and weather conditions.
x Always adjust your speed and driving style to road, terrain, traffic, and weather conditions.
x Always avoid sudden, sharp maneuvers that increase the risk of loss of vehicle control or getting stuck.
x When driving off-road look and think ahead, expect the unexpected.
x To reduce the risk of loss of control and serious personal injury, never use the cruise control when driving off-road. Cruise control is designed for highway use. It is completely unsuitable for off-road situations and can even be dangerous when used off-road.
NOTICE
Always make sure the vehicle has enough ground clearance. Severe damage to the underbody can occur if the vehicle bottoms out. The damage could disable the vehicle and leave you stranded.
x While driving off-road do not drag the clutch or rest one foot on the clutch pedal. Otherwise, in bumpy terrain you might press the clutch accidentally, resulting in loss of vehicle control. In addition, the frictional connection between the engine and transmission is lost. Further, driving while dragging the clutch causes fast wear of the clutch lining.
“Tread lightly” is an educational program designed to increase public awareness of land use regulations and responsibilities in our nation's wilderness areas. Volkswagen supports the U.S. Forest Service and the Bureau of Land Management in encouraging you to preserve our national forests and other public and private lands by “treading lightly”.

Vehicles with Keyless Access
If the ignition will not start after reconnecting the vehicle battery, lock the vehicle from the outside and
unlock it again ⇒  Unlocking or locking the vehicle with Keyless Access. Then try to start the ignition again. If the ignition cannot be switched on, contact an authorized Volkswagen dealer, an authorized Volkswagen Service Facility, or another qualified workshop for assistance.
Automatic electrical load deactivation
If the vehicle battery drain is high, the intelligent onboard electrical system management automatically takes steps to help prevent battery drain.
x The idle speed is increased so that the alternator provides more power.
x The power to devices that consume a lot of electricity is cut back or switched off completely.
x When the engine is started, the power supply to the 12 Volt sockets is temporarily interrupted.
The onboard electrical system management cannot always keep the battery from being drained. For example, the battery will drain if the engine is not running, but the ignition is switched on or the parking lights are left on for a long time when parked.
Battery disconnection in an accident with airbag deployment
In vehicles with a battery in the luggage compartment, the electrical connection to the battery is disconnected automatically in a collision with airbag deployment. This helps to prevent a short-circuit.
What drains the battery?
x Long periods when the engine is not running, especially when the ignition is on.
x Using electrical systems or devices when the engine is switched off.
x Leaving the vehicle unlocked for several days when not in use.
x The selector lever is left for a long period of time in any position other than (P) when the ignition is
switched off ⇒  Automatic transmission: Selector lever.
WARNING
Failure to use the proper battery with proper mounting and connections may cause short circuits, fires, and serious personal injuries.
x Always use only maintenance-free or cycle-free, leakproof batteries with the same specifications and dimensions as the original equipment battery. Specifications are listed on the battery housing.
WARNING
When the vehicle battery is charged, it produces highly explosive hydrogen gas.
x Charge vehicle batteries only in well-ventilated areas.
x Never charge a frozen or thawed battery. A dead battery can freeze at temperatures around +32 °F (0 °C).
x You must replace the vehicle battery if it was frozen.
x Incorrectly connected cables can cause a short-circuit. First connect the positive cable (+) and then the negative cable (-).
