Driving Through Water
Although your vehicle is capable of driving through
water, there are a number of precautions that must be
considered before entering the water.
NOTE: Your vehicle is capable of water fording in up to
20 inches (51 cm) of water, while crossing small rivers or
streams. To maintain optimal performance of your vehi-
cle’s heating and ventilation system it is recommended to
switch the system into recirculation mode during water
fording.
CAUTION!
When driving through water, do not exceed 5 mph
(8 km/h). Always check water depth before entering,
as a precaution, and check all fluids afterward. Driv-
ing through water may cause damage that may not be
covered by the new vehicle limited warranty.
Driving through water more than a few inches/centi-
meters deep will require extra caution to ensure safety
and prevent damage to your vehicle. If you must drive
through water, try to determine the depth and the bottom
condition (and location of any obstacles) prior to enter-
ing. Proceed with caution and maintain a steady con-
trolled speed less than 5 mph (8 km/h) in deep water to
minimize wave effects.
Flowing Water
If the water is swift flowing and rising (as in storm run-off),
avoid crossing until the water level recedes and/or the
flow rate is reduced. If you must cross flowing water avoid
depths in excess of 9 inches (23 cm). The flowing water can
erode the streambed, causing your vehicle to sink into
deeper water. Determine exit point(s) that are downstream
of your entry point to allow for drifting.
