What to do if the Vehicle is Stuck in
Sand, Mud, Snow or Ice
WARNING
DO NOT spin the wheels faster than
35 mph (55 km/h). Spinning a tire at
speedometer readings faster than 35
mph (55 km/h) can be dangerous.
Tires can explode from spinning too
fast. Under some conditions, a tire
may be spinning at a speed twice that
shown on the speedometer. Any re-
sulting tire explosion could cause in-
jury or death to a bystander or passen-
ger, as well as extensive vehicle dam-
age: including tire, transmission,
and/or rear axle malfunction.
These suggestions are provided to improve
the ability to free a vehicle if the vehicle
gets stuck in sand, mud, snow, or ice:
• Move the gearshift lever or selector
from First to Reverse
• Apply light pressure on the
accelerator pedal while the
transmission is in gear
• Remove your foot from the
accelerator while shifting
• Do not race the engine
• For best traction and safety, avoid
spinning the wheels
Follow these practices to avoid
transmission damage:
• Always start vehicle in motion with
the shift lever in first gear.
• Be sure that transmission is fully
engaged in gear before releasing
the clutch pedal (manual only).
• Do not shift into reverse while the
vehicle is moving.
• If the vehicle needs to be
recovered from being stuck, do not
permit the vehicle to be towed for
long distances without removing
the driveshaft.
If tire chains are needed, make sure they
are installed on both sides of the driving
axle. Installing chains on only one side of
the axle can cause equipment damage.
CAUTION
Chains on the tires of only one tandem
axle can damage the driveline U-joints
and the inter-axle differential. Repairs
could be costly and time-consuming.
Failure to comply may result in equip-
ment damage.
Towing the Vehicle
A dealer or commercial towing service will
have the necessary equipment to safely
tow the vehicle and should be able to make
arrangements to limit any damage to the
vehicle. The towing service and the dealer
should be aware of towing regulations and
safety precautions.
The towing service will ensure that the
following precautions are taken:
• Use of a safety chain system
• Abide by all local towing
regulations
• Ensure that the towing device does
not contact any surfaces that could
be damaged while in transit
• If towing from the front, ensure that
the rear axles are prepared for
towing
• If towing from the rear, ensure that
all body components such as roof,
side, and chassis fairings are
secured properly to avoid damage
while in transit
