the airbags may have also
damaged important functions in
the vehicle, such as the fuel

appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough toinflate the airbag, windshields arebroken by vehicle deformation.
Additional windshield breakage mayalso occur from the front outboardpassenger airbag.

Engine Oil Pressure
Gauge
Metric
English
The oil pressure gauge shows theengine oil pressure in psi (poundsper square inch) or kPa (kilopascals)when the engine is running.
Oil pressure may vary with enginespeed, outside temperature and oilviscosity, but readings above thelow pressure zone indicate thenormal operating range.
Areadinginthelowpressurezonemay be caused by a dangerouslylow oil level or other problemcausing low oil pressure.

engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty. Check
the oil level as soon as possible.
Add oil if required, but if the oil
level is within the operating range
and the oil pressure is still low,
have the vehicle serviced. Always
follow the maintenance schedule
for changing engine oil.
Engine Coolant
Temperature Gauge
Metric
English
This gauge shows the enginecoolant temperature.
It also provides an indicator of howhard the vehicle is working. During amajority of the operation, the gaugewill read 100 °C (210 °F) or less.If the vehicle is pulling a load orgoing up hills, it is normal for thetemperature to fluctuate andapproach the 122 °C (250 °F) mark.If the gauge reaches the 125 °C(260 °F) mark, it indicates that thecooling system is working beyondits capacity.

Voltmeter Gauge
When the engine is not running, butthe ignition is on, this gauge showsthe battery's state of charge inDC volts.
When the engine is running, thegauge shows the condition of thecharging system. Readings betweenthe low and high warning zonesindicate the normal operating range.
Readings in the low warning zonemay occur when a large number ofelectrical accessories are operatingin the vehicle and the engine is leftat an idle for an extended period.This condition is normal since the
charging system is not able toprovide full power at engine idle. Asengine speeds are increased, thiscondition should correct itself ashigher engine speeds allow thecharging system to create maximumpower.
The vehicle can be only driven for ashort time with the reading in eitherwarning zone. If it must be driven,turn off all unnecessaryaccessories.
Readings in either warning zoneindicate a possible problem in theelectrical system. Have the vehicleserviced as soon as possible.
