Pop-up Pictograms
TCS traction control system and electronic stability control
At vehicle ignition, the TCS icon appears for approximately 2 seconds and then
disappears.
If it remains on steadily (not flashing) after ignition, or if it is on steadily while you are
driving, the TCS system may not be fully functional or the operation may be completely
disabled. If this happens, your vehicle will still have normal service braking and it still can
be driven, although without the benefits of the TCS system.
Flashes slowly when TCS Mud/Snow mode is turned on using the Mud/Snow switch.
Flashes quickly when TCS intervenes to reduce risk of loss of control.

This pictogram indicates that the A/C system pressure is too high. If the A/C pressure is

NOTE

A/C System Pressure Low
This pictogram indicates that the A/C system pressure is too low. If the A/C pressure is
too low, the compressor clutch disengages and the fan stops.
NOTE
